What solves my problem: I am using 64 bit Windows 7, so I thought I could install 64 bit Wamp. After I Installed the 32-bit version the error does not appear. So something in the developing process at Wamp went wrong...

'It' requires a dll file called cvextern.dll . 'It' can be either your own cs file or some other third party dll which you are using in your project.

To call native dlls to your own cs file, copy the dll into your project's root\lib directory and add it as an existing item. (Add -Existing item) and use Dllimport with correct location.

For third party , copy the native library to the folder where the third party library resides and add it as an existing item.

After building make sure that the required dlls are appearing in Build folder. In some cases it may not appear or get replaced in Build folder. Delete the Build folder manually and build again.

DLL Export Viewer by NirSoft can be used to display exported functions in a DLL.

This utility displays the list of all exported functions and their virtual memory addresses for the specified DLL files. You can easily copy the memory address of the desired function, paste it into your debugger, and set a breakpoint for this memory address. When this function is called, the debugger will stop in the beginning of this function.

     {
          // now use XSD
          returnVal =
            await DoProcess(
              @helperRoot + "xsd.exe", "/c /namespace:RuleBook /language:CS " + "\"" + @destinationfilename + "\"");

I had the same problem and my problem had nothing to do with paths. One of my dll-s was written in c++ and it turnes out that if your visual studio doesn't know how to open a dll file it will say that it did not find it. What i did was locate which dll it did not find, than searched for that dll in my directories and opened it in a separate visual studio window. When trying to navigate through Solution explorer of that project, visual studio said that it cannot show what is inside and that i need some extra extensions, so that it can open those files. Surely enough, after installing the recomended extension (in my case something to do with c++) the

"This application has failed to start because xxx.dll was not found."

error miraculously dissapeared.

If you want plain C exports, use a C project not C++. C++ DLLs rely on name-mangling for all the C++isms (namespaces etc...). You can compile your code as C by going into your project settings under C/C++->Advanced, there is an option "Compile As" which corresponds to the compiler switches /TP and /TC.

If you still want to use C++ to write the internals of your lib but export some functions unmangled for use outside C++, see the second section below.

Exporting/Importing DLL Libs in VC++

What you really want to do is define a conditional macro in a header that will be included in all of the source files in your DLL project:

#ifdef LIBRARY_EXPORTS
#    define LIBRARY_API __declspec(dllexport)
#else
#    define LIBRARY_API __declspec(dllimport)
#endif

Then on a function that you want to be exported you use LIBRARY_API:

LIBRARY_API int GetCoolInteger();

In your library build project create a define LIBRARY_EXPORTS this will cause your functions to be exported for your DLL build.

Since LIBRARY_EXPORTS will not be defined in a project consuming the DLL, when that project includes the header file of your library all of the functions will be imported instead.

If your library is to be cross-platform you can define LIBRARY_API as nothing when not on Windows:

#ifdef _WIN32
#    ifdef LIBRARY_EXPORTS
#        define LIBRARY_API __declspec(dllexport)
#    else
#        define LIBRARY_API __declspec(dllimport)
#    endif
#elif
#    define LIBRARY_API
#endif

When using dllexport/dllimport you do not need to use DEF files, if you use DEF files you do not need to use dllexport/dllimport. The two methods accomplish the same task different ways, I believe that dllexport/dllimport is the recommended method out of the two.

Exporting unmangled functions from a C++ DLL for LoadLibrary/PInvoke

If you need this to use LoadLibrary and GetProcAddress, or maybe importing from another language (i.e PInvoke from .NET, or FFI in Python/R etc) you can use extern "C" inline with your dllexport to tell the C++ compiler not to mangle the names. And since we are using GetProcAddress instead of dllimport we don't need to do the ifdef dance from above, just a simple dllexport:

The Code:

#define EXTERN_DLL_EXPORT extern "C" __declspec(dllexport)

EXTERN_DLL_EXPORT int getEngineVersion() {
  return 1;
}

EXTERN_DLL_EXPORT void registerPlugin(Kernel &K) {
  K.getGraphicsServer().addGraphicsDriver(
    auto_ptr<GraphicsServer::GraphicsDriver>(new OpenGLGraphicsDriver())
  );
}

And here's what the exports look like with Dumpbin /exports:

  Dump of file opengl_plugin.dll

  File Type: DLL

  Section contains the following exports for opengl_plugin.dll

    00000000 characteristics
    49866068 time date stamp Sun Feb 01 19:54:32 2009
        0.00 version
           1 ordinal base
           2 number of functions
           2 number of names

    ordinal hint RVA      name

          1    0 0001110E getEngineVersion = @ILT+265(_getEngineVersion)
          2    1 00011028 registerPlugin = @ILT+35(_registerPlugin)

So this code works fine:

m_hDLL = ::LoadLibrary(T"opengl_plugin.dll");

m_pfnGetEngineVersion = reinterpret_cast<fnGetEngineVersion *>(
  ::GetProcAddress(m_hDLL, "getEngineVersion")
);
m_pfnRegisterPlugin = reinterpret_cast<fnRegisterPlugin *>(
  ::GetProcAddress(m_hDLL, "registerPlugin")
);

I was having the same problem. Turned out I was missing the ./Views/Web.config file, because I created the project from an empty ASP.NET application instead of using an ASP.NET MVC template.

For ASP.NET MVC 5, a vanilla ./Views/Web.config file contains the following:

You should think carefully about changes over time, versioning, stability, compatibility, etc.

If there are two apps that use the shared code, do you want to force those apps to change together, in case they need to be compatible with each other? Then use the dll. All the exe's will be using the same code.

Or do you want to isolate them from each other, so that you can change one and be confident you haven't broken the other. Then use the static lib.

DLL hell is when you probably SHOULD HAVE used a static lib, but you used a dll instead, and not all the exes are comaptible with it.

It has been pointed out in 2016 by Andrew Cuthbert that git diff locks files as well until you quit out of it.

That won't be the case with Git 2.23 (Q3 2019).

See commit 3aef54e (11 Jul 2019) by Johannes Schindelin (dscho).

diff: munmap() file contents before running external diff

When running an external diff from, say, a diff tool, it is safe to assume that we want to write the files in question.
On Windows, that means that there cannot be any other process holding an open handle to said files, or even just a mapped region.

So let's make sure that git diff itself is not holding any open handle to the files in question.

In fact, we will just release the file pair right away, as the external diff uses the files we just wrote, so we do not need to hold the file contents in memory anymore.

This fixes git-for-windows#1315

Running "git diff"^(man) while allowing external diff in a state with unmerged paths used to segfault, which has been corrected with Git 2.30 (Q1 2021).

See commit d668518, commit 2469593 (06 Nov 2020) by Jinoh Kang (iamahuman).

diff: allow passing NULL to diff_free_filespec_data()

^{Signed-off-by: Jinoh Kang
Signed-off-by: Junio C Hamano}

Commit 3aef54e8b8 ("diff: munmap() file contents before running external diff", Git v2.22.1) introduced calls to diff_free_filespec_data in run_external_diff, which may pass NULL pointers.

Fix this and prevent any such bugs in the future by making diff_free_filespec_data(NULL) a no-op.

Fixes: 3aef54e8b8 ("diff: munmap() file contents before running external diff")

This is not exactly a hot topic, but I have a factory class that allows a dll to create an instance and return it as a DLL. It is what I came looking for but couldn't find exactly.

It is called like,

IHTTP_Server *server = SN::SN_Factory<IHTTP_Server>::CreateObject();
IHTTP_Server *server2 =
      SN::SN_Factory<IHTTP_Server>::CreateObject(IHTTP_Server_special_entry);

where IHTTP_Server is the pure virtual interface for a class created either in another DLL, or the same one.

DEFINE_INTERFACE is used to give a class id an interface. Place inside interface;

An interface class looks like,

class IMyInterface
{
    DEFINE_INTERFACE(IMyInterface);

public:
    virtual ~IMyInterface() {};

    virtual void MyMethod1() = 0;
    ...
};

The header file is like this

#if !defined(SN_FACTORY_H_INCLUDED)
#define SN_FACTORY_H_INCLUDED

#pragma once

The libraries are listed in this macro definition. One line per library/executable. It would be cool if we could call into another executable.

#define SN_APPLY_LIBRARIES(L, A)                          \
    L(A, sn, "sn.dll")                                    \
    L(A, http_server_lib, "http_server_lib.dll")          \
    L(A, http_server, "")

Then for each dll/exe you define a macro and list its implementations. Def means that it is the default implementation for the interface. If it is not the default, you give a name for the interface used to identify it. Ie, special, and the name will be IHTTP_Server_special_entry.

#define SN_APPLY_ENTRYPOINTS_sn(M)                                     \
    M(IHTTP_Handler, SNI::SNI_HTTP_Handler, sn, def)                   \
    M(IHTTP_Handler, SNI::SNI_HTTP_Handler, sn, special)

#define SN_APPLY_ENTRYPOINTS_http_server_lib(M)                        \
    M(IHTTP_Server, HTTP::server::server, http_server_lib, def)

#define SN_APPLY_ENTRYPOINTS_http_server(M)

With the libraries all setup, the header file uses the macro definitions to define the needful.

#define APPLY_ENTRY(A, N, L) \
    SN_APPLY_ENTRYPOINTS_##N(A)

#define DEFINE_INTERFACE(I) \
    public: \
        static const long Id = SN::I##_def_entry; \
    private:

namespace SN
{
    #define DEFINE_LIBRARY_ENUM(A, N, L) \
        N##_library,

This creates an enum for the libraries.

    enum LibraryValues
    {
        SN_APPLY_LIBRARIES(DEFINE_LIBRARY_ENUM, "")
        LastLibrary
    };

    #define DEFINE_ENTRY_ENUM(I, C, L, D) \
        I##_##D##_entry,

This creates an enum for interface implementations.

    enum EntryValues
    {
        SN_APPLY_LIBRARIES(APPLY_ENTRY, DEFINE_ENTRY_ENUM)
        LastEntry
    };

    long CallEntryPoint(long id, long interfaceId);

This defines the factory class. Not much to it here.

    template <class I>
    class SN_Factory
    {
    public:
        SN_Factory()
        {
        }

        static I *CreateObject(long id = I::Id )
        {
            return (I *)CallEntryPoint(id, I::Id);
        }
    };
}

#endif //SN_FACTORY_H_INCLUDED

Then the CPP is,

#include "sn_factory.h"

#include <windows.h>

Create the external entry point. You can check that it exists using depends.exe.

extern "C"
{
    __declspec(dllexport) long entrypoint(long id)
    {
        #define CREATE_OBJECT(I, C, L, D) \
            case SN::I##_##D##_entry: return (int) new C();

        switch (id)
        {
            SN_APPLY_CURRENT_LIBRARY(APPLY_ENTRY, CREATE_OBJECT)
        case -1:
        default:
            return 0;
        }
    }
}

The macros set up all the data needed.

namespace SN
{
    bool loaded = false;

    char * libraryPathArray[SN::LastLibrary];
    #define DEFINE_LIBRARY_PATH(A, N, L) \
        libraryPathArray[N##_library] = L;

    static void LoadLibraryPaths()
    {
        SN_APPLY_LIBRARIES(DEFINE_LIBRARY_PATH, "")
    }

    typedef long(*f_entrypoint)(long id);

    f_entrypoint libraryFunctionArray[LastLibrary - 1];
    void InitlibraryFunctionArray()
    {
        for (long j = 0; j < LastLibrary; j++)
        {
            libraryFunctionArray[j] = 0;
        }

        #define DEFAULT_LIBRARY_ENTRY(A, N, L) \
            libraryFunctionArray[N##_library] = &entrypoint;

        SN_APPLY_CURRENT_LIBRARY(DEFAULT_LIBRARY_ENTRY, "")
    }

    enum SN::LibraryValues libraryForEntryPointArray[SN::LastEntry];
    #define DEFINE_ENTRY_POINT_LIBRARY(I, C, L, D) \
            libraryForEntryPointArray[I##_##D##_entry] = L##_library;
    void LoadLibraryForEntryPointArray()
    {
        SN_APPLY_LIBRARIES(APPLY_ENTRY, DEFINE_ENTRY_POINT_LIBRARY)
    }

    enum SN::EntryValues defaultEntryArray[SN::LastEntry];
        #define DEFINE_ENTRY_DEFAULT(I, C, L, D) \
            defaultEntryArray[I##_##D##_entry] = I##_def_entry;

    void LoadDefaultEntries()
    {
        SN_APPLY_LIBRARIES(APPLY_ENTRY, DEFINE_ENTRY_DEFAULT)
    }

    void Initialize()
    {
        if (!loaded)
        {
            loaded = true;
            LoadLibraryPaths();
            InitlibraryFunctionArray();
            LoadLibraryForEntryPointArray();
            LoadDefaultEntries();
        }
    }

    long CallEntryPoint(long id, long interfaceId)
    {
        Initialize();

        // assert(defaultEntryArray[id] == interfaceId, "Request to create an object for the wrong interface.")
        enum SN::LibraryValues l = libraryForEntryPointArray[id];

        f_entrypoint f = libraryFunctionArray[l];
        if (!f)
        {
            HINSTANCE hGetProcIDDLL = LoadLibraryA(libraryPathArray[l]);

            if (!hGetProcIDDLL) {
                return NULL;
            }

            // resolve function address here
            f = (f_entrypoint)GetProcAddress(hGetProcIDDLL, "entrypoint");
            if (!f) {
                return NULL;
            }
            libraryFunctionArray[l] = f;
        }
        return f(id);
    }
}

Each library includes this "cpp" with a stub cpp for each library/executable. Any specific compiled header stuff.

#include "sn_pch.h"

Setup this library.

#define SN_APPLY_CURRENT_LIBRARY(L, A) \
    L(A, sn, "sn.dll")

An include for the main cpp. I guess this cpp could be a .h. But there are different ways you could do this. This approach worked for me.

#include "../inc/sn_factory.cpp"

Right now, you're creating an instance of every type defined in the assembly. You only need to create a single instance of Class1 in order to call the method:

class Program
{
    static void Main(string[] args)
    {
        var DLL = Assembly.LoadFile(@"C:\visual studio 2012\Projects\ConsoleApplication1\ConsoleApplication1\DLL.dll");

        var theType = DLL.GetType("DLL.Class1");
        var c = Activator.CreateInstance(theType);
        var method = theType.GetMethod("Output");
        method.Invoke(c, new object[]{@"Hello"});

        Console.ReadLine();
    }
}

Windows dll error 126 can have many root causes. The most useful methods I have found to debug this are:

1. Use dependency walker to look for any obvious problems (which you have already done)
2. Use the sysinternals utility Process Monitor http://technet.microsoft.com/en-us/sysinternals/bb896645 from Microsoft to trace all file access while your dll is trying to load. With this utility, you will see everything that that dll is trying to pull in and usually the problem can be determined from there.

There is an command line application called "ShowVer" at CodeProject:

ShowVer.exe command-line VERSIONINFO display program

As usual the application comes with an exe and the source code (VisualC++ 6).

Out outputs all the meta data available:

Only static functions are called with class name.

classname::Staicfunction();

Non static functions have to be called using objects.

classname obj;
obj.Somefunction();

This is exactly what your error means. Since your function is non static you have to use a object reference to invoke it.

This might be impossible or at least very hard. The DLL's contents don't depend (a lot) on it being written in C++; it's all machine code. That code might have been optimized so a lot of information that was present in the original source code is simply gone.

That said, here is one article that goes through a lot of material about doing this.

The .exe is the program. The .dll is a library that a .exe (or another .dll) may call into.

What sakthivignesh says can be true in that one .exe can use another as if it were a library, and this is done (for example) with some COM components. In this case, the "slave" .exe is a separate program (strictly speaking, a separate process - perhaps running on a separate machine), but one that accepts and handles requests from other programs/components/whatever.

However, if you just pick a random .exe and .dll from a folder in your Program Files, odds are that COM isn't relevant - they are just a program and its dynamically-linked libraries.

Using Win32 APIs, a program can load and use a DLL using the LoadLibrary and GetProcAddress API functions, IIRC. There were similar functions in Win16.

COM is in many ways an evolution of the DLL idea, originally concieved as the basis for OLE2, whereas .NET is the descendant of COM. DLLs have been around since Windows 1, IIRC. They were originally a way of sharing binary code (particularly system APIs) between multiple running programs in order to minimise memory use.

Creating DLL File

1. Open Visual Studio then select File -> New -> Project

2. Select Visual C# -> Class library

3. Compile Project Or Build the solution, to create Dll File

4. Go to the class library folder (Debug Folder)

Gory details

A DLL uses the PE executable format, and it's not too tricky to read that information out of the file.

See this MSDN article on the PE File Format for an overview. You need to read the MS-DOS header, then read the IMAGE_NT_HEADERS structure. This contains the IMAGE_FILE_HEADER structure which contains the info you need in the Machine member which contains one of the following values

• IMAGE_FILE_MACHINE_I386 (0x014c)
• IMAGE_FILE_MACHINE_IA64 (0x0200)
• IMAGE_FILE_MACHINE_AMD64 (0x8664)

This information should be at a fixed offset in the file, but I'd still recommend traversing the file and checking the signature of the MS-DOS header and the IMAGE_NT_HEADERS to be sure you cope with any future changes.

Use ImageHelp to read the headers...

You can also use the ImageHelp API to do this - load the DLL with LoadImage and you'll get a LOADED_IMAGE structure which will contain a pointer to an IMAGE_NT_HEADERS structure. Deallocate the LOADED_IMAGE with ImageUnload.

...or adapt this rough Perl script

Here's rough Perl script which gets the job done. It checks the file has a DOS header, then reads the PE offset from the IMAGE_DOS_HEADER 60 bytes into the file.

It then seeks to the start of the PE part, reads the signature and checks it, and then extracts the value we're interested in.

#!/usr/bin/perl
#
# usage: petype <exefile>
#
$exe = $ARGV[0];

open(EXE, $exe) or die "can't open $exe: $!";
binmode(EXE);
if (read(EXE, $doshdr, 64)) {

   ($magic,$skip,$offset)=unpack('a2a58l', $doshdr);
   die("Not an executable") if ($magic ne 'MZ');

   seek(EXE,$offset,SEEK_SET);
   if (read(EXE, $pehdr, 6)){
       ($sig,$skip,$machine)=unpack('a2a2v', $pehdr);
       die("No a PE Executable") if ($sig ne 'PE');

       if ($machine == 0x014c){
            print "i386\n";
       }
       elsif ($machine == 0x0200){
            print "IA64\n";
       }
       elsif ($machine == 0x8664){
            print "AMD64\n";
       }
       else{
            printf("Unknown machine type 0x%lx\n", $machine);
       }
   }
}

close(EXE);

I had this happen to me with a file referenced in the same assembly, not a separate dll. Once I excluded the file from the project and then included it again, everything worked fine.

In My Visual Studio 2015, I ensured that the offending Visual Studio Project's Reference Paths List is empty:

To browse .NET code dependencies, you can use the capabilities of the tool NDepend. The tool proposes:

• a dependency graph
• a dependency matrix,
• and also some C# LINQ queries can be edited (or generated) to browse dependencies.

For example such query can look like:

from m in Methods 
let depth = m.DepthOfIsUsing("NHibernate.NHibernateUtil.Entity(Type)") 
where depth  >= 0 && m.IsUsing("System.IDisposable")
orderby depth
select new { m, depth }

And its result looks like: (notice the code metric depth, 1 is for direct callers, 2 for callers of direct callers...) (notice also the Export to Graph button to export the query result to a Call Graph)

The dependency graph looks like:

The dependency matrix looks like:

The dependency matrix is de-facto less intuitive than the graph, but it is more suited to browse complex sections of code like:

Disclaimer: I work for NDepend

ctypes will be the easiest thing to use but (mis)using it makes Python subject to crashing. If you are trying to do something quickly, and you are careful, it's great.

I would encourage you to check out Boost Python. Yes, it requires that you write some C++ code and have a C++ compiler, but you don't actually need to learn C++ to use it, and you can get a free (as in beer) C++ compiler from Microsoft.

To incorporate third-party DLLs into my VS 2008 C++ project I did the following (you should be able to translate into 2010, 2012 etc.)...

I put the header files in my solution with my other header files, made changes to my code to call the DLLs' functions (otherwise why would we do all this?). :^) Then I changed the build to link the LIB code into my EXE, to copy the DLLs into place, and to clean them up when I did a 'clean' - I explain these changes below.

Suppose you have 2 third-party DLLs, A.DLL and B.DLL, and you have a stub LIB file for each (A.LIB and B.LIB) and header files (A.H and B.H).

• Create a "lib" directory under your solution directory, e.g. using Windows Explorer.
• Copy your third-party .LIB and .DLL files into this directory

(You'll have to make the next set of changes once for each source build target that you use (Debug, Release).)

1. Make your EXE dependent on the LIB files

   • Go to Configuration Properties -> Linker -> Input -> Additional Dependencies, and list your .LIB files there one at a time, separated by spaces: A.LIB B.LIB
   • Go to Configuration Properties -> General -> Additional Library Directories, and add your "lib" directory to any you have there already. Entries are separated by semicolons. For example, if you already had $(SolutionDir)fodder there, you change it to $(SolutionDir)fodder;$(SolutionDir)lib to add "lib".

2. Force the DLLs to get copied to the output directory

   • Go to Configuration Properties -> Build Events -> Post-Build Event
   • Put the following in for Command Line (for the switch meanings, see "XCOPY /?" in a DOS window):

   XCOPY "$(SolutionDir)"\lib\*.DLL "$(TargetDir)" /D /K /Y

   • You can put something like this for Description:

   Copy DLLs to Target Directory

   • Excluded From Build should be No. Click OK.

3. Tell VS to clean up the DLLs when it cleans up an output folder:

   • Go to Configuration Properties -> General -> Extensions to Delete on Clean, and click on "..."; add *.dll to the end of the list and click OK.

ieshims.dll is an artefact of Vista/7 where a shim DLL is used to proxy certain calls (such as CreateProcess) to handle protected mode IE, which doesn't exist on XP, so it is unnecessary. wer.dll is related to Windows Error Reporting and again is probably unused on Windows XP which has a slightly different error reporting system than Vista and above.

I would say you shouldn't need either of them to be present on XP and would normally be delay loaded anyway.

You can compile with either Cygwin's g++ or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll (and others) PATH to the system Windows PATH, before any cygwin style paths.

Thus add: ;C:\cygwin64\bin to the end of your Windows system PATH variable.

Also, to compile for use in CMD or PowerShell, you may need to use:

x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe

_{(This invokes the cross-compiler, if installed.)}

VS2019 V16.6.3

For me the problem was somehow the main .proj file ended up with an entry like this for the project whose DLL wasn't getting copied to the parent project bin folder:

<ProjectReference Include="Project B.csproj">
  <Project>{blah blah}</Project>
  <Name>Project B</Name>
  <Private>True</Private>
</ProjectReference>

I manually deleted the line <Private>True</Private> and the DLL was then copied to the main project bin folder on every build of the main project.

If you go to the reference of the problem project in the references folder of the main project, click it and view properties there is a "Copy Local" setting. The private tag equates to this setting, but for me for some reason changing copy local had no effect on the private tag in the .proj file.

Annoyingly I didn't change the copy local value for the reference, no idea how it got set that way and another day wasted tracking down a stupid problem with VS.

Thanks to all the other answers that helped zone me in on the cause.

When I changed the .Net frame work version of the App pool in which the particular project was hosted, I was able to resolve this particular issue.

App pool -> advanced settings -> .Net frame work version (changed v2.0 to v4.0)

If you are using laragon open the php.ini

In the interface of laragon menu-> php-> php.ini

when you open the file look for ; extension_dir = "./"

create another one without **; ** with the path of your php version to the folder ** ext ** for example

extension_dir = "C: \ laragon \ bin \ php \ php-7.3.11-Win32-VC15-x64 \ ext"

I was getting the below error in my 32 bit application.

System.Reflection.Assembly.GetExecutingAssembly().Location

To Fix The "Missing "server" JVM at C:\Program Files\Java\jre7\bin\server\jvm­­.dll, please install or use the JRE or JDK that contains these missing components.

Follow these steps:

Go to oracle.com and install Java JRE7 (Check if Java 6 is not installed already)

After that, go to C:/Program files/java/jre7/bin

Here, create an folder called Server

Now go into the C:/Program files/java/jre7/bin/client folder

Copy all the data in this folder into the new C:/Program files/java/jre7/bin/Server folder

This happens because Oracle dropped support for Windows XP (which doesn't have RegDeleteKeyExA used by the installer in its ADVAPI32.DLL by the way) as described in http://mail.openjdk.java.net/pipermail/openjfx-dev/2013-July/009005.html. Yet while the official support for XP has ended, the Java binaries are still (as of Java 8u20 EA b05 at least) XP-compatible - only the installer isn't...

Because of that, the solution is actually quite easy:

1. get 7-Zip (or any other good unpacker), unpack the distribution .exe manually, it has one .zip file inside of it (tools.zip), extract it too,

2. use unpack200 from JDK8 to unpack all .pack files to .jar files (older unpacks won't work properly); JAVA_HOME environment variable should be set to your Java unpack root, e.g. "C:\Program Files\Java\jdk8" - you can specify it implicitly by e.g.

   SET JAVA_HOME=C:\Program Files\Java\jdk8
   

   • Unpack all files with a single command (in batch file):

     FOR /R %%f IN (*.pack) DO "%JAVA_HOME%\bin\unpack200.exe" -r -v "%%f" "%%~pf%%~nf.jar"
     

   • Unpack all files with a single command (command line from JRE root):

     FOR /R %f IN (*.pack) DO "bin\unpack200.exe" -r -v "%f" "%~pf%~nf.jar"
     

   • Unpack by manually locating the files and unpacking them one-by-one:

     %JAVA_HOME%\bin\unpack200 -r packname.pack packname.jar
     

   where packname is for example rt

3. point the tool you want to use (e.g. Netbeans) to the %JAVA_HOME% and you're good to go.

Note: you probably shouldn't do this just to use Java 8 in your web browser or for any similar reason (installing JRE 8 comes to mind); security flaws in early updates of major Java version releases are (mind me) legendary, and adding to that no real support for neither XP nor Java 8 on XP only makes matters much worse. Not to mention you usually don't need Java in your browser (see e.g. http://nakedsecurity.sophos.com/2013/01/15/disable-java-browsers-homeland-security/ - the topic is already covered on many pages, just Google it if you require further info). In any case, AFAIK the only thing required to apply this procedure to JRE is to change some of the paths specified above from \bin\ to \lib\ (the file placement in installer directory tree is a bit different) - yet I strongly advise against doing it.

See also: How can I get the latest JRE / JDK as a zip file rather than EXE or MSI installer?, JRE 1.7 - java version - returns: java/lang/NoClassDefFoundError: java/lang/Object

DLLs are shared libraries which are used by other windows programs while EXEs are the files which are actually executed and are linked to DLL files so that they can use DLLs.
Both are of same format, PE(portable executable or format of machine code in windows in simple words).
In other words EXEs contain the entry point(main) and the DLLs contain the library functions.. You cannot execute a file which just contains library functions you can just use them via other programs.

But still there are programs like rundll32.exe which provides that entry point and some minimal framework required by DLL functions to be called.
The point that I want to make is, you can never execute a DLL file you can just use it's code by providing an entry point through an EXE or some other program.

Here is the solution I found:

How to fix the missing MSVCR711.dll problem

You can find MSVCR71.dll file in following location of your installed SQL Developer 2.1 directory:

sqldeveloper-2.1.0.63.10\sqldeveloper\jdk\jre\bin\MSVCR71.dll

Or you could check out the freeware StampVer for Win32 exe/dll files.
It will only change the file and product versions though if they have a version resource already. It cannot add a version resource if one doesn’t exist.

I've had the same issue in a VB6 program I'm writing, where a Form uses a ScriptControl object to run VBScripts selected by the User.

It worked fine until the other day, when it suddenly started displaying 'Runtime error 429' when the VBScript attempted to create a Scripting.FileSystemObject.

After going mad for an entire day, trying all the solutions proposed here, I began suspecting the problem was in my application.

Fortunately, I had a backup version of that form: I compared their codes, and discovered that inadvertently I had set UseSafeSubset property of my ScriptControl object to True.

It was the only difference in the form, and after restoring the backup copy it worked like a charm.

Hope this can be useful to someone. Up with VB6! :-)

This answer is totally unrelated to the OP's situation, and is a very unlikely scenario for anyone else too, but just in case it may help someone ...

In my case I was getting "Could not load file or assembly 'System.Windows.Forms, Version=4.0.0.0 ..." because I had disassembled and reassembled the program using ILDAsm.exe and ILAsm.exe from .Net Framework / SDK version 2. Switching to ILDAsm.exe and ILAsm.exe from .Net Framework / SDK version 4 fixed the problem.

(Strangely, even though doing what I did may seem like an obvious error, the resulting EXE file that didn't work did indicate that it targeted .Net 4 when examined with JetBrains dotPeek.)

Information about missing entry point error installing legacy VB6 compiled applications on Windows 10 which I hope could be useful to someone.

Missing OCX files can be found in the "OS\System folder" of the Visual Basic 6.0 installer package. Today I copied the relevant OCX file (from our network) to the local computer

And then I typed the commands below, as administrator, which normally work to register it.

cd \windows\syswow64
regsvr32.exe /u mscomctl.ocx
regsvr32.exe /i mscomctl.ocx

(add the path to the locally copied file for the /i command)

However today I got errors from both these regsvr32.exe commands.

The second error was giving the DllImport missing entry point error which is similar to the error mentioned by the original poster.

To resolve, one of the things I tried was leaving out the switch -

regsvr32.exe mscomctl.ocx

To my surprise it then said it was successful. To confirm, the application started up properly afterwards.

A static library(.a) is a library that can be linked directly into the final executable produced by the linker,it is contained in it and there is no need to have the library into the system where the executable will be deployed.

A shared library(.so) is a library that is linked but not embedded in the final executable, so will be loaded when the executable is launched and need to be present in the system where the executable is deployed.

A dynamic link library on windows(.dll) is like a shared library(.so) on linux but there are some differences between the two implementations that are related to the OS (Windows vs Linux) :

A DLL can define two kinds of functions: exported and internal. The exported functions are intended to be called by other modules, as well as from within the DLL where they are defined. Internal functions are typically intended to be called only from within the DLL where they are defined.

An SO library on Linux doesn't need special export statement to indicate exportable symbols, since all symbols are available to an interrogating process.

try "configuration properties -> debugging -> environment" and set the PATH variable in run-time

If you need to load a file that's relative to some directory where you already are (like in the current directory), here's an easy solution:

File f;

if (System.getProperty("sun.arch.data.model").equals("32")) {
    // 32-bit JVM
    f = new File("mylibfile32.so");
} else {
    // 64-bit JVM
    f = new File("mylibfile64.so");
}
System.load(f.getAbsolutePath());

I also ran into this problem, but the solution that seems to be a common thread here, and I saw elsewhere on the web, is "[re]install the redistributable package". However, for me that does not work, as the problem arose when running the installer for our product (which installs the redistributable package) to test our shiny new Visual Studio 2015 builds.

The issue came up because the DLL files listed are not located in the Visual Studio install path (for example, C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\redist) and thus had not been added to the install. These api-ms-win-* dlls get installed to a Windows 10 SDK install path as part of the Visual Studio 2015 install (e.g. C:\Program Files (x86)\Windows Kits\10\Redist).

Installing on Windows 10 worked fine, but installing on Windows 7 required adding these DLL files to our product install. For more information, see Update for Universal C Runtime in Windows which describes the addition of these dependencies caused by Visual Studio 2015 and provides downloads for various Windows platforms; also see Introducing the Universal CRT which describes the redesign of the CRT libraries. Of particular interest is item 6 under the section titled Distributing Software that uses the Universal CRT:

Updated September 11, 2015: App-local deployment of the Universal CRT is supported. To obtain the binaries for app-local deployment, install the Windows Software Development Kit (SDK) for Windows 10. The binaries will be installed to C:\Program Files (x86)\Windows Kits\10\Redist\ucrt. You will need to copy all of the DLLs with your app (note that the set of DLL files are necessary is different on different versions of Windows, so you must include all of the DLL files in order for your program to run on all supported versions of Windows).

I get this every time I want to create an application in VC++.

Right-click the project, select Properties then under 'Configuration properties | C/C++ | Code Generation', select "Multi-threaded Debug (/MTd)" for Debug configuration.

Note that this does not change the setting for your Release configuration - you'll need to go to the same location and select "Multi-threaded (/MT)" for Release.

I got the same error but I solved by using regsvr32.exe in C:\Windows\SysWOW64. Because we use x64 system. So if your machine is also x64, the ocx/dll must registered also with regsvr32 x64 version

I had a similar problem. I had installed JDK7 update 1 but couldn't use it (probably because I found a JRE6 that I deleted after installing JDK7). Uninstalling JDK7 was impossible. The solution was to add the JRE registry entries by hand.

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment]
"CurrentVersion"="1.7"

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.7]
"JavaHome"="C:\\Program Files\\Java\\jre7"
"RuntimeLib"="C:\\Program Files\\Java\\jre7\\bin\\client\\jvm.dll"

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.7.0_01]
"JavaHome"="C:\\Program Files\\Java\\jre7"
"RuntimeLib"="C:\\Program Files\\Java\\jre7\\bin\\client\\jvm.dll"

You'll have to adjust the above to your own directories and version.

If this doesn't help, there's still JavaRa http://raproducts.org/wordpress/ .

After:

C:\app\oracle32\product\12.1.0\client_1\bin;
C:\app\oracle64\product\12.1.0\client_1\bin;

started working... Hope this helps everyone.

You have to add reference to

Microsoft.VisualStudio.QualityTools.UnitTestFramework.dll 

It can be found at C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\PublicAssemblies\ directory (for VS2010 professional or above; .NET Framework 4.0).

or right click on your project and select: Add Reference... > .NET:

Use the free DLL Export Viewer, it is very easy to use.

The details in the comments section above did not work for me (VS 2013) when trying to copy the output dll from one C++ project to the release and debug folder of another C# project within the same solution.

I had to add the following post build-action (right click on the project that has a .dll output) then properties -> configuration properties -> build events -> post-build event -> command line

now I added these two lines to copy the output dll into the two folders:

xcopy /y $(TargetPath) $(SolutionDir)aeiscontroller\bin\Release
xcopy /y $(TargetPath) $(SolutionDir)aeiscontroller\bin\Debug

I use the csc.exe compiler called from a .vbs script.

In your xyz.cs script, add the following lines after the directives (my example is for the Renci SSH):

using System;
using Renci;//FOR THE SSH
using System.Net;//FOR THE ADDRESS TRANSLATION
using System.Reflection;//FOR THE Assembly

//+ref>"C:\Program Files (x86)\Microsoft\ILMerge\Renci.SshNet.dll"
//+res>"C:\Program Files (x86)\Microsoft\ILMerge\Renci.SshNet.dll"
//+ico>"C:\Program Files (x86)\Microsoft CAPICOM 2.1.0.2 SDK\Samples\c_sharp\xmldsig\resources\Traffic.ico"

The ref, res and ico tags will be picked up by the .vbs script below to form the csc command.

Then add the assembly resolver caller in the Main:

public static void Main(string[] args)
{
    AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve);
    .

...and add the resolver itself somewhere in the class:

    static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
    {
        String resourceName = new AssemblyName(args.Name).Name + ".dll";

        using (var stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName))
        {
            Byte[] assemblyData = new Byte[stream.Length];
            stream.Read(assemblyData, 0, assemblyData.Length);
            return Assembly.Load(assemblyData);
        }

    }

I name the vbs script to match the .cs filename (e.g. ssh.vbs looks for ssh.cs); this makes running the script numerous times a lot easier, but if you aren't an idiot like me then a generic script could pick up the target .cs file from a drag-and-drop:

    Dim name_,oShell,fso
    Set oShell = CreateObject("Shell.Application")
    Set fso = CreateObject("Scripting.fileSystemObject")

    'TAKE THE VBS SCRIPT NAME AS THE TARGET FILE NAME
    '################################################
    name_ = Split(wscript.ScriptName, ".")(0)

    'GET THE EXTERNAL DLL's AND ICON NAMES FROM THE .CS FILE
    '#######################################################
    Const OPEN_FILE_FOR_READING = 1
    Set objInputFile = fso.OpenTextFile(name_ & ".cs", 1)

    'READ EVERYTHING INTO AN ARRAY
    '#############################
    inputData = Split(objInputFile.ReadAll, vbNewline)

    For each strData In inputData

        if left(strData,7)="//+ref>" then 
            csc_references = csc_references & " /reference:" &         trim(replace(strData,"//+ref>","")) & " "
        end if

        if left(strData,7)="//+res>" then 
            csc_resources = csc_resources & " /resource:" & trim(replace(strData,"//+res>","")) & " "
        end if

        if left(strData,7)="//+ico>" then 
            csc_icon = " /win32icon:" & trim(replace(strData,"//+ico>","")) & " "

1. There is a program called "Depends"
2. If you have cygwin installed, nothing simpler then ldd file.exe

After a bit of googling, it seems that there never was a separate redistributable for Visual C++ 2003 (7.1). At least that is what a post on the microsoft forum says.

You may however be able to extract the runtime DLLs from the VC 7.1 DST timezone update.

I have come across the same problem, In my case I had two 32 bit pcs. One with .NET4.5 installed and other one was fresh PC.

my 32-bit cpp dll(Release mode build) was working fine with .NET installed PC but Not with fresh PC where I got the below error

Unable to load DLL 'PrinterSettings.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

finally,

I just built my project in Debug mode configuration and this time my cpp dll was working fine.

You need to do a couple of things to use the library:

1. Make sure that you have both the *.lib and the *.dll from the library you want to use. If you don't have the *.lib, skip #2

2. Put a reference to the *.lib in the project. Right click the project name in the Solution Explorer and then select Configuration Properties->Linker->Input and put the name of the lib in the Additional Dependencies property.

3. You have to make sure that VS can find the lib you just added so you have to go to the Tools menu and select Options... Then under Projects and Solutions select VC++ Directories,edit Library Directory option. From within here you can set the directory that contains your new lib by selecting the 'Library Files' in the 'Show Directories For:' drop down box. Just add the path to your lib file in the list of directories. If you dont have a lib you can omit this, but while your here you will also need to set the directory which contains your header files as well under the 'Include Files'. Do it the same way you added the lib.

After doing this you should be good to go and can use your library. If you dont have a lib file you can still use the dll by importing it yourself. During your applications startup you can explicitly load the dll by calling LoadLibrary (see: http://msdn.microsoft.com/en-us/library/ms684175(VS.85).aspx for more info)

Remember to use #include < Foo.h > as opposed to #include "foo.h". The former searches the include path. The latter uses the local project files.

Answer is very simple use the .NET Framework tools sn.exe. So open the Visual Studio 2008 Command Prompt and then point to the dll’s folder you want to get the public key,

Use the following command,

sn –T myDLL.dll

This will give you the public key token. Remember one thing this only works if the assembly has to be strongly signed.

Example

C:\WINNT\Microsoft.NET\Framework\v3.5>sn -T EdmGen.exe

Microsoft (R) .NET Framework Strong Name Utility  Version 3.5.21022.8
Copyright (c) Microsoft Corporation.  All rights reserved.

Public key token is b77a5c561934e089

Quoting http://php.net/manual/en/intro.mssql.php:

The MSSQL extension is not available anymore on Windows with PHP 5.3 or later. SQLSRV, an alternative driver for MS SQL is available from Microsoft: » http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx.

Once you downloaded that, follow the instructions at this page:

• Loading the Microsoft Drivers for PHP for SQL Server

In a nutshell:

Put the driver file in your PHP extension directory.
Modify the php.ini file to include the driver. For example:

extension=php_sqlsrv_53_nts_vc9.dll  

Restart the Web server.

See Also (copied from that page)

• System Requirements (Microsoft Drivers for PHP for SQL Server)
• Getting Started
• Programming Guide
• SQLSRV Driver API Reference (Microsoft Drivers for PHP for SQL Server)

The PHP Manual for the SQLSRV extension is located at http://php.net/manual/en/sqlsrv.installation.php and offers the following for Installation:

The SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. The SQLSRV download comes with several driver files. Which driver file you use will depend on 3 factors: the PHP version you are using, whether you are using thread-safe or non-thread-safe PHP, and whether your PHP installation was compiled with the VC6 or VC9 compiler. For example, if you are running PHP 5.3, you are using non-thread-safe PHP, and your PHP installation was compiled with the VC9 compiler, you should use the php_sqlsrv_53_nts_vc9.dll file. (You should use a non-thread-safe version compiled with the VC9 compiler if you are using IIS as your web server). If you are running PHP 5.2, you are using thread-safe PHP, and your PHP installation was compiled with the VC6 compiler, you should use the php_sqlsrv_52_ts_vc6.dll file.

The drivers can also be used with PDO.

There are static libraries (LIB) and dynamic libraries (DLL) - but note that .LIB files can be either static libraries (containing object files) or import libraries (containing symbols to allow the linker to link to a DLL).

Libraries are used because you may have code that you want to use in many programs. For example if you write a function that counts the number of characters in a string, that function will be useful in lots of programs. Once you get that function working correctly you don't want to have to recompile the code every time you use it, so you put the executable code for that function in a library, and the linker can extract and insert the compiled code into your program. Static libraries are sometimes called 'archives' for this reason.

Dynamic libraries take this one step further. It seems wasteful to have multiple copies of the library functions taking up space in each of the programs. Why can't they all share one copy of the function? This is what dynamic libraries are for. Rather than building the library code into your program when it is compiled, it can be run by mapping it into your program as it is loaded into memory. Multiple programs running at the same time that use the same functions can all share one copy, saving memory. In fact, you can load dynamic libraries only as needed, depending on the path through your code. No point in having the printer routines taking up memory if you aren't doing any printing. On the other hand, this means you have to have a copy of the dynamic library installed on every machine your program runs on. This creates its own set of problems.

As an example, almost every program written in 'C' will need functions from a library called the 'C runtime library, though few programs will need all of the functions. The C runtime comes in both static and dynamic versions, so you can determine which version your program uses depending on particular needs.

keep sqljdbc_auth.dll in your windows/system32 folder and it will work.Download sqljdbc driver from this link Unzip it and you will find sqljdbc_auth.dll.Now keep the sqljdbc_auth.dll inside system32 folder and run your program

You can have separate configuration file, but you'll have to read it "manually", the ConfigurationManager.AppSettings["key"] will read only the config of the running assembly.

Assuming you're using Visual Studio as your IDE, you can right click the desired project ? Add ? New item ? Application Configuration File

This will add App.config to the project folder, put your settings in there under <appSettings> section. In case you're not using Visual Studio and adding the file manually, make sure to give it such name: DllName.dll.config, otherwise the below code won't work properly.

Now to read from this file have such function:

string GetAppSetting(Configuration config, string key)
{
    KeyValueConfigurationElement element = config.AppSettings.Settings[key];
    if (element != null)
    {
        string value = element.Value;
        if (!string.IsNullOrEmpty(value))
            return value;
    }
    return string.Empty;
}

And to use it:

Configuration config = null;
string exeConfigPath = this.GetType().Assembly.Location;
try
{
    config = ConfigurationManager.OpenExeConfiguration(exeConfigPath);
}
catch (Exception ex)
{
    //handle errror here.. means DLL has no sattelite configuration file.
}

if (config != null)
{
    string myValue = GetAppSetting(config, "myKey");
    ...
}

You'll also have to add reference to System.Configuration namespace in order to have the ConfigurationManager class available.

When building the project, in addition to the DLL you'll have DllName.dll.config file as well, that's the file you have to publish with the DLL itself.

The above is basic sample code, for those interested in a full scale example, please refer to this other answer.

When the DLL was created an import lib is usually automatically created and you should use that linked in to your program along with header files to call it but if not then you can manually call windows functions like LoadLibrary and GetProcAddress to get it working.

The error indicates that the DLL is either not a COM DLL or it's corrupt. If it's not a COM DLL and not being used as a COM DLL by an application then there is no need to register it.
From what you say in your question (the service is not registered) it seems that we are talking about a service not correctly installed. I will try to reinstall the application.

Argh :D not the fastest

Process.Start("notepad C:\test.txt");

Contrary to the suggestions by some of the other answers, using the DllImport attribute is still the correct approach.

I honestly don't understand why you can't do just like everyone else in the world and specify a relative path to your DLL. Yes, the path in which your application will be installed differs on different people's computers, but that's basically a universal rule when it comes to deployment. The DllImport mechanism is designed with this in mind.

In fact, it isn't even DllImport that handles it. It's the native Win32 DLL loading rules that govern things, regardless of whether you're using the handy managed wrappers (the P/Invoke marshaller just calls LoadLibrary). Those rules are enumerated in great detail here, but the important ones are excerpted here:

Before the system searches for a DLL, it checks the following:

• If a DLL with the same module name is already loaded in memory, the system uses the loaded DLL, no matter which directory it is in. The system does not search for the DLL.
• If the DLL is on the list of known DLLs for the version of Windows on which the application is running, the system uses its copy of the known DLL (and the known DLL's dependent DLLs, if any). The system does not search for the DLL.

---

If SafeDllSearchMode is enabled (the default), the search order is as follows:

1. The directory from which the application loaded.
2. The system directory. Use the GetSystemDirectory function to get the path of this directory.
3. The 16-bit system directory. There is no function that obtains the path of this directory, but it is searched.
4. The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
5. The current directory.
6. The directories that are listed in the PATH environment variable. Note that this does not include the per-application path specified by the App Paths registry key. The App Paths key is not used when computing the DLL search path.

So, unless you're naming your DLL the same thing as a system DLL (which you should obviously not be doing, ever, under any circumstances), the default search order will start looking in the directory from which your application was loaded. If you place the DLL there during the install, it will be found. All of the complicated problems go away if you just use relative paths.

Just write:

[DllImport("MyAppDll.dll")] // relative path; just give the DLL's name
static extern bool MyGreatFunction(int myFirstParam, int mySecondParam);

But if that doesn't work for whatever reason, and you need to force the application to look in a different directory for the DLL, you can modify the default search path using the SetDllDirectory function.
Note that, as per the documentation:

After calling SetDllDirectory, the standard DLL search path is:

1. The directory from which the application loaded.
2. The directory specified by the lpPathName parameter.
3. The system directory. Use the GetSystemDirectory function to get the path of this directory.
4. The 16-bit system directory. There is no function that obtains the path of this directory, but it is searched.
5. The Windows directory. Use the GetWindowsDirectory function to get the path of this directory.
6. The directories that are listed in the PATH environment variable.

So as long as you call this function before you call the function imported from the DLL for the first time, you can modify the default search path used to locate DLLs. The benefit, of course, is that you can pass a dynamic value to this function that is computed at run-time. That isn't possible with the DllImport attribute, so you will still use a relative path (the name of the DLL only) there, and rely on the new search order to find it for you.

You'll have to P/Invoke this function. The declaration looks like this:

[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern bool SetDllDirectory(string lpPathName);

You may need to install ATL if your COM objects use ATL, as described by this KB article:

These libraries will probably have to be supplied by developers to ensure the correct version.

use the relevant RegSvcs as specified in the above link

c:\Windows\Microsoft. NET\Framework\v4.0.30319\RegSvcs.exe ....\Shared\Your.dll /tlb:Your.tlb

I am on a 64 bit system, and I only got this to work after installing both the 32 and 64 bit versions of the redistributable. I did not try the 64 bit version by itself due to the other posters' warnings about using the 32 bit version (and am too lazy to uninstall the 32 bit version now that I have it working), so I don't know if the 32 bit version is needed or not in cases like mine.

I had the same problem. Here's what I did:

1. I downloaded pywin32 Wheel file from here, then

2. I uninstalled the pywin32 module. To uninstall execute the following command in Command Prompt.

   pip uninstall pywin32

3. Then, I reinstalled pywin32. To install it, open the Command Prompt in the same directory where the pywin32 wheel file lies. Then execute the following command.

   pip install <Name of the wheel file with extension> Wheel file will be like: piwin32-XXX-cpXX-none-win32.whl

It solvs the problem for me. You may also like to give it a try. Hope it work for you as well.

you also should specify def name in the project settings here:

Configuration > Properties/Input/Advanced/Module > Definition File

I should add: You should not be putting your dll's into \system32\ anyway! Modify your code, modify your installer... find a home for your bits that is NOT anywhere under c:\windows\

For example, your installer puts your dlls into:

\program files\<your app dir>\

or

\program files\common files\<your app name>\

(Note: The way you actually do this is to use the environment var: %ProgramFiles% or %ProgramFiles(x86)% to find where Program Files is.... you do not assume it is c:\program files\ ....)

and then sets a registry tag :

HKLM\software\<your app name>
-- dllLocation

The code that uses your dlls reads the registry, then dynamically links to the dlls in that location.

The above is the smart way to go.

You do not ever install your dlls, or third party dlls into \system32\ or \syswow64. If you have to statically load, you put your dlls in your exe dir (where they will be found). If you cannot predict the exe dir (e.g. some other exe is going to call your dll), you may have to put your dll dir into the search path (avoid this if at all poss!)

system32 and syswow64 are for Windows provided files... not for anyone elses files. The only reason folks got into the bad habit of putting stuff there is because it is always in the search path, and many apps/modules use static linking. (So, if you really get down to it, the real sin is static linking -- this is a sin in native code and managed code -- always always always dynamically link!)

The command should be the following script:

ilmerge myExe.exe Dll1.dll /target:winexe /targetplatform:"v4,c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.0\" /out:merged.exe /out:merged.exe

Let’s say you are making an executable that uses some functions found in a library.

If the library you are using is static, the linker will copy the object code for these functions directly from the library and insert them into the executable.

Now if this executable is run it has every thing it needs, so the executable loader just loads it into memory and runs it.

If the library is dynamic the linker will not insert object code but rather it will insert a stub which basically says this function is located in this DLL at this location.

Now if this executable is run, bits of the executable are missing (i.e the stubs) so the loader goes through the executable fixing up the missing stubs. Only after all the stubs have been resolved will the executable be allowed to run.

To see this in action delete or rename the DLL and watch how the loader will report a missing DLL error when you try to run the executable.

Hence the name Dynamic Link Library, parts of the linking process is being done dynamically at run time by the executable loader.

One a final note, if you don't link to the DLL then no stubs will be inserted by the linker, but Windows still provides the GetProcAddress API that allows you to load an execute the DLL function entry point long after the executable has started.

Installing vc_redist.x86.exe works for me even though you have a 64-bit machine.

Knowing the error message would be rather valuable. It is meant to provide info, even though it doesn't make any sense to you it does to us. Being forced to guess, I'd say that the DLL is a 32-bit DirectX filter. In which case this should be the proper course of action:

cd c:\windows\syswow64
move ..\system32\dllname.ax .
regsvr32.exe dllname.ax

This must be run at an elevated command prompt so that UAC cannot stop the registry access that's required. Ask more questions about this at superuser.com

For VB6:

You need to declare your C functions as __stdcall, otherwise you get "invalid calling convention" type errors. About other your questions:

can I take arguments by pointer/reference from the VB front-end?

Yes, use ByRef/ByVal modifiers.

Can the DLL call a theoretical function in the front-end?

Yes, use AddressOf statement. You need to pass function pointer to dll before.

Or have a function take a "function pointer" (I don't even know if that's possible) from VB and call it?)

Yes, use AddressOf statement.

update (more questions appeared :)):

to load it into VB, do I just do the usual method (what I would do to load winsock.ocx or some other runtime, but find my DLL instead) or do I put an API call into a module?

You need to decaler API function in VB6 code, like next:

Private Declare Function SHGetSpecialFolderLocation Lib "shell32" _
   (ByVal hwndOwner As Long, _
    ByVal nFolder As Long, _
    ByRef pidl As Long) As Long

Use the SC (service control) command, it gives you a lot more options than just start & stop.

If you are using httpclient 4.2, then you need to write a small bit of extra code. I wanted to be able to customize both the "TLS enabled protocols" (e.g. TLSv1.1 specifically, and neither TLSv1 nor TLSv1.2) as well as the cipher suites.

public class CustomizedSSLSocketFactory
    extends SSLSocketFactory
{
    private String[] _tlsProtocols;
    private String[] _tlsCipherSuites;

    public CustomizedSSLSocketFactory(SSLContext sslContext,
                                      X509HostnameVerifier hostnameVerifier,
                                      String[] tlsProtocols,
                                      String[] cipherSuites)
    {
        super(sslContext, hostnameVerifier);

        if(null != tlsProtocols)
            _tlsProtocols = tlsProtocols;
        if(null != cipherSuites)
            _tlsCipherSuites = cipherSuites;
    }

    @Override
    protected void prepareSocket(SSLSocket socket)
    {
        // Enforce client-specified protocols or cipher suites
        if(null != _tlsProtocols)
            socket.setEnabledProtocols(_tlsProtocols);

        if(null != _tlsCipherSuites)
            socket.setEnabledCipherSuites(_tlsCipherSuites);
    }
}

Then:

    SSLContext sslContext = SSLContext.getInstance("TLS");

    sslContext.init(null, getTrustManagers(), new SecureRandom());

    // NOTE: not javax.net.SSLSocketFactory
    SSLSocketFactory sf = new CustomizedSSLSocketFactory(sslContext,
                                                         null,
                                                         [TLS protocols],
                                                         [TLS cipher suites]);

    Scheme httpsScheme = new Scheme("https", 443, sf);
    SchemeRegistry schemeRegistry = new SchemeRegistry();
    schemeRegistry.register(httpsScheme);

    ConnectionManager cm = new BasicClientConnectionManager(schemeRegistry);

    HttpClient client = new DefaultHttpClient(cmgr);
    ...

You may be able to do this with slightly less code, but I mostly copy/pasted from a custom component where it made sense to build-up the objects in the way shown above.

I think you would like this interactive website, which often helps me build complex Crontab directives: https://crontab.guru/

Documentation can be found e.g. at MDN. Note that .split() is not a jQuery method, but a native string method.

If you use .split() on a string, then you get an array back with the substrings:

var str = 'something -- something_else';
var substr = str.split(' -- ');
// substr[0] contains "something"
// substr[1] contains "something_else"

If this value is in some field you could also do:

tRow.append($('<td>').text($('[id$=txtEntry2]').val().split(' -- ')[0])));

For those of you that do need a non jQuery answer you can simple add the following:

xmlhttp.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'));

A very simple example can be sen here:

xmlhttp.open("POST","example.html",true);
xmlhttp.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'));
xmlhttp.send();

try this:

final String currentTime    = String.valueOf(System.currentTimeMillis());

Any server side stuff such as php declaration must get evaluated in the host file (file with a .php extension) inside the script tags such as below

<script type="text/javascript">
    var1 = "<?php echo 'Hello';?>";
</script>

Then in the .js file, you can use the variable

alert(var1);

If you try to evaluate php declaration in the .js file, it will NOT work

Here is what worked for me.

Install the userspace USB programming library development files

sudo apt-get install libusb-1.0-0-dev
sudo updatedb && locate libusb.h

The path should appear as (or similar)

/usr/include/libusb-1.0/libusb.h

Include the header to your C code

#include <libusb-1.0/libusb.h>

Compile your C file

gcc -o example example.c -lusb-1.0

DOMDocument is a great choice. It's a module specifically designed for creating and manipulating XML documents. You can create a document from scratch, or open existing documents (or strings) and navigate and modify their structures.

$xml = new DOMDocument();
$xml_album = $xml->createElement("Album");
$xml_track = $xml->createElement("Track");
$xml_album->appendChild( $xml_track );
$xml->appendChild( $xml_album );

$xml->save("/tmp/test.xml");

To re-open and write:

$xml = new DOMDocument();
$xml->load('/tmp/test.xml');
$nodes = $xml->getElementsByTagName('Album') ;
if ($nodes->length > 0) {
   //insert some stuff using appendChild()
}

//re-save
$xml->save("/tmp/test.xml");

DecimalFormat df=new DecimalFormat("0.00");

Use this code to get exact two decimal points. Even if the value is 0.0 it will give u 0.00 as output.

Instead if you use:

DecimalFormat df=new DecimalFormat("#.00");  

It wont convert 0.2659 into 0.27. You will get an answer like .27.

This command:

git ls-tree --full-tree -r --name-only HEAD

In order to use Qt with dynamic linking you have to specify the lib files (usually qtmaind.lib, QtCored4.lib and QtGuid4.lib for the "Debug" configration) in
Properties » Linker » Input » Additional Dependencies.

You also have to specify the path where the libs are, namely in
Properties » Linker » General » Additional Library Directories.

And you need to make the corresponding .dlls are accessible at runtime, by either storing them in the same folder as your .exe or in a folder that is on your path.

This is the most coder-friendly version of specifying a unicode character:

degree_sign= u'\N{DEGREE SIGN}'

Note: must be a capital N in the \N construct to avoid confusion with the '\n' newline character. The character name inside the curly braces can be any case.

It's easier to remember the name of a character than its unicode index. It's also more readable, ergo debugging-friendly. The character substitution happens at compile time: the .py[co] file will contain a constant for u'°':

>>> import dis
>>> c= compile('u"\N{DEGREE SIGN}"', '', 'eval')
>>> dis.dis(c)
  1           0 LOAD_CONST               0 (u'\xb0')
              3 RETURN_VALUE
>>> c.co_consts
(u'\xb0',)
>>> c= compile('u"\N{DEGREE SIGN}-\N{EMPTY SET}"', '', 'eval')
>>> c.co_consts
(u'\xb0-\u2205',)
>>> print c.co_consts[0]

This answer is similar to others with requests and BeautifulSoup, but using list comprehension.

Because find_all() is the most popular method in the Beautiful Soup search API, you can use soup("a") as a shortcut of soup.findAll("a") and using list comprehension:

import requests
from bs4 import BeautifulSoup

URL = "http://www.yourwebsite.com"
page = requests.get(URL)
soup = BeautifulSoup(page.content, features='lxml')
# Find links
all_links = [link.get("href") for link in soup("a")]
# Only external links
ext_links = [link.get("href") for link in soup("a") if "http" in link.get("href")]

https://www.crummy.com/software/BeautifulSoup/bs4/doc/#calling-a-tag-is-like-calling-find-all

Just to reiterate what has been posted for other shells, in Bash the following works:

alias blah='function _blah(){ echo "First: $1"; echo "Second: $2"; };_blah'

Running the following:

blah one two

Gives the output below:

First: one
Second: two

You can use json_decode() to convert a json string to a PHP object/array.

Eg.

Input:

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));
var_dump(json_decode($json, true));

Output:

object(stdClass)#1 (5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

    ["a"] => int(1)
    ["b"] => int(2)

    ["e"] => int(5)
}

Few Points to remember:

• json_decode requires the string to be a valid json else it will return NULL.
• In the event of a failure to decode, json_last_error() can be used to determine the exact nature of the error.
• Make sure you pass in utf8 content, or json_decode may error out and just return a NULL value.

I searched for multiple options to get my git reset to specific commit, but most of them aren't so satisfactory.

I generally use this to reset the git to the specific commit in source tree.

1. select commit to reset on sourcetree.

2. In dropdowns select the active branch , first Parent Only

3. And right click on "Reset branch to this commit" and select hard reset option (soft, mixed and hard)

4. and then go to terminal git push -f

You should be all set!

If you go thru this IBM link on java, it says that on 32 bit windows the recommended heap size is 1.5 GB and the Maximum heap size is 1.8 GB. So your jvm does not gets initialized for -Xmx2G and above.

Also if you go thru this SO answer, clearly the DLL bindings are an issue for memory reservation changing which is no trivial task. Hence what may be recommended is that you go for 64-bit Windows and a 64-bit JVM. while it will chew up more RAM, you will have much more contiguous virtual address space.

Accessing a name and assigning a name are different. In your case, you are just accessing a name.

If you assign to a variable within a function, that variable is assumed to be local unless you declare it global. In the absence of that, it is assumed to be global.

>>> x = 1         # global 
>>> def foo():
        print x       # accessing it, it is global

>>> foo()
1
>>> def foo():   
        x = 2        # local x
        print x 

>>> x            # global x
1
>>> foo()        # prints local x

In case that you are interested in writing a test, then github.com/stretchr/testify/assert is your friend.

Import the library at the very beginning of the file:

import (
    "github.com/stretchr/testify/assert"
)

Then inside the test you do:

func TestEquality_SomeSlice (t * testing.T) {
    a := []int{1, 2}
    b := []int{2, 1}
    assert.Equal(t, a, b)
}

The error prompted will be:

To a kill a specific port in Linux use below command

sudo fuser -k Port_Number/tcp

replace Port_Number with your occupied port.

In the first example, you are reassigning the variable a, while in the second one you are modifying the data in-place, using the += operator.

See the section about 7.2.1. Augmented assignment statements :

An augmented assignment expression like x += 1 can be rewritten as x = x + 1 to achieve a similar, but not exactly equal effect. In the augmented version, x is only evaluated once. Also, when possible, the actual operation is performed in-place, meaning that rather than creating a new object and assigning that to the target, the old object is modified instead.

+= operator calls __iadd__. This function makes the change in-place, and only after its execution, the result is set back to the object you are "applying" the += on.

__add__ on the other hand takes the parameters and returns their sum (without modifying them).

comboBox1.Text = " ";

This is the best and easiest way to set your combo box back to default settings without erasing the contents of the combo box.

I had exactly the same problem with my VS 2013 solutions when I install VS 2017 and Crystal Reports SP21. In fact it's because VS does not necessarily convert the solution in the first launch.

Once you have installed Crystal Report SP 21, make sure that VS 2017 upgrade your solution : a window must appear "SAP Crystal Reports, version for Visual" with a radio button "Convert the solution".

Screenshot in french :

When I used the menu "File / Open / Project/Solution", the conversion was not done.

I have to do that :

1. Add VS 2017 on the tasks bar
2. Run VS 2017 and Open the solution with File menu
3. Try to build the project, errors appear with Crystal Reports
4. Close VS 2017
5. Right click on VS 2017 shortcur in then tasks bar and open the solution directly
6. The conversion run this time, you can open .rpt and the solution build without error.

There is an important bit that is not mentioned in the article to which you linked and that is flex-basis. By default flex-basis is auto.

From the spec:

If the specified flex-basis is auto, the used flex basis is the value of the flex item’s main size property. (This can itself be the keyword auto, which sizes the flex item based on its contents.)

Each flex item has a flex-basis which is sort of like its initial size. Then from there, any remaining free space is distributed proportionally (based on flex-grow) among the items. With auto, that basis is the contents size (or defined size with width, etc.). As a result, items with bigger text within are being given more space overall in your example.

If you want your elements to be completely even, you can set flex-basis: 0. This will set the flex basis to 0 and then any remaining space (which will be all space since all basises are 0) will be proportionally distributed based on flex-grow.

li {
    flex-grow: 1;
    flex-basis: 0;
    /* ... */
}

This diagram from the spec does a pretty good job of illustrating the point.

And here is a working example with your fiddle.

Better and clean example using JS only

Step 1 - Create your java script and place it in your HTML page.

<script type="text/javascript">
    function ShowLoading(e) {
        var div = document.createElement('div');
        var img = document.createElement('img');
        img.src = 'loading_bar.GIF';
        div.innerHTML = "Loading...<br />";
        div.style.cssText = 'position: fixed; top: 5%; left: 40%; z-index: 5000; width: 422px; text-align: center; background: #EDDBB0; border: 1px solid #000';
        div.appendChild(img);
        document.body.appendChild(div);
        return true;
        // These 2 lines cancel form submission, so only use if needed.
        //window.event.cancelBubble = true;
        //e.stopPropagation();
    }
</script>

in your form call the java script function on submit event.

<form runat="server"  onsubmit="ShowLoading()">
</form>

Soon after you submit the form, it will show you the loading image.

Use java -cp myjar.jar com.mypackage.myClass.

1. If the class is not in a package then simply java -cp myjar.jar myClass.

2. If you are not within the directory where myJar.jar is located, then you can do:

   1. On Unix or Linux platforms:

      java -cp /location_of_jar/myjar.jar com.mypackage.myClass

   2. On Windows:

      java -cp c:\location_of_jar\myjar.jar com.mypackage.myClass

It does work in Firefox (including 2.0.0.20). See http://jsbin.com/akili (add /edit to the url to edit):

<p id="one">One</p>
<a href="#" onclick="document.getElementById('one').id = 'two'; return false">Link2</a>

The first click changes the id to "two", the second click errors because the element with id="one" now can't be found!

Perhaps you have another element already with id="two" (FYI you can't have more than one element with the same id).

pod setup works and should only take 10 mins on a solid connection. After that run: pod install --verbose and you should see all the comments you would normally see when running a dependancy manager.

You can create a plethora of different chart types relatively quickly with loads of customizable options.

I did it in my project ,

make a div with back ground url as gif , which is nothing but animation gif

<div class="busyindicatorClass"> </div>

.busyindicatorClass
{
background-url///give animation here
}

in your ajax call , add this class to the div and in ajax success remove the class.

it will do the trick thatsit.

let me know if you need antthing else , i can give you more details

in the ajax success remove the class

success: function(data) {
    remove class using jquery
  }

I never managed to make the '\t' metacharacter work with grep. However I found two alternate solutions:

1. Using <Ctrl-V> <TAB> (hitting Ctrl-V then typing tab)
2. Using awk: foo | awk '/\t/'

SQL 2005 and above has this feature built-in. Use the ROW_NUMBER() function. It is excellent for web-pages with a << Prev and Next >> style browsing:

Syntax:

SELECT
    *
FROM
    (
        SELECT
            ROW_NUMBER () OVER (ORDER BY MyColumnToOrderBy) AS RowNum,
            *
        FROM
            Table_1
    ) sub
WHERE
    RowNum = 23

You may use it with like the following.

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_marginTop="15dp">
    <Space
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"/>
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Save"/>
    <Space
        android:layout_weight="1"
        android:layout_height="wrap_content"

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Reset"/>
    <Space
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"/>
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="cancel"/>
    <Space
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"/>

Use a parameterized query to prevent Sql injections (secutity problem)

Use the using statement so the connection will be closed and resources will be disposed.

using(var connection = new SqlConnection("connectionString"))
{
    connection.Open();
    var sql = "INSERT INTO Main(FirstName, SecondName) VALUES(@FirstName, @SecondName)";
    using(var cmd = new SqlCommand(sql, connection))
    {
        cmd.Parameters.AddWithValue("@FirstName", txFirstName.Text);
        cmd.Parameters.AddWithValue("@SecondName", txSecondName.Text);

        cmd.ExecuteNonQuery();

Scandit is a startup whose goal is to replace bulky, expensive laser barcode scanners with cheap mobile phones.

There are SDKs for Android, iOS, Windows, C API/Linux, React Native, Cordova/PhoneGap, Xamarin.

There is also Scandit Barcode Scanner SDK for the Web which the WebAssembly version of the SDK. It runs in modern browsers, also on phones.

There's a client library that also provides a barcode picker component. It can be used like this:

<div id="barcode-picker" style="max-width: 1280px; max-height: 80%;"></div>

<script src="https://unpkg.com/scandit-sdk"></script>
<script>
    console.log('Loading...');
    ScanditSDK.configure("xxx", {
engineLocation: "https://unpkg.com/scandit-sdk/build/"
    }).then(() => {
      console.log('Loaded');
      ScanditSDK.BarcodePicker.create(document.getElementById('barcode-picker'), {
        playSoundOnScan: true,
        vibrateOnScan: true
      }).then(function(barcodePicker) {
        console.log("Ready");
        barcodePicker.applyScanSettings(new ScanditSDK.ScanSettings({
          enabledSymbologies: ["ean8", "ean13", "upca", "upce", "code128", "code39", "code93", "itf", "qr"],
          codeDuplicateFilter: 1000
        }));
        barcodePicker.onScan(function(barcodes) {
          console.log(barcodes);
        });
      });
    });
</script>

This is the fastest way:

if ($coll->isEmpty()) {...}

Other solutions like count do a bit more than you need which costs slightly more time.

Plus, the isEmpty() name quite precisely describes what you want to check there so your code will be more readable.

Try this

$('input:checkbox:checked').click(function(){
    var val=(this).val(); // it will get value from checked checkbox;
})

Here flag is true if checked otherwise false

var flag=$('#ans').attr('checked');

Again this will make cheked

$('#ans').attr('checked',true);

The video tag can play audio as well. Given the audio tag doesn't seem to be behaving as it should be, you can just use the video tag for audio:

<video autoplay muted id="audio1" src="your.mp3" type="audio/mp3">
    Your browser does not support the <code>video</code> element.
</video>
<script>
    unmuteButton.addEventListener('click', function() 
        { 
            if ( unmuteButton.innerHTML == "unmute" )
            {
                unmuteButton.innerHTML = "mute";
                audio1.muted = false; 
            } else {
                unmuteButton.innerHTML = "unmute";
                audio1.muted = true; 
            }
        });
</script>

<xsl:call-template> is a close equivalent to calling a function in a traditional programming language.

You can define functions in XSLT, like this simple one that outputs a string.

<xsl:template name="dosomething">
  <xsl:text>A function that does something</xsl:text>
</xsl:template>

This function can be called via <xsl:call-template name="dosomething">.

<xsl:apply-templates> is a little different and in it is the real power of XSLT: It takes any number of XML nodes (whatever you define in the select attribute), iterates them (this is important: apply-templates works like a loop!) and finds matching templates for them:

<!-- sample XML snippet -->
<xml>
  <foo /><bar /><baz />
</xml>

<!-- sample XSLT snippet -->
<xsl:template match="xml">
  <xsl:apply-templates select="*" /> <!-- three nodes selected here -->
</xsl:template>

<xsl:template match="foo"> <!-- will be called once -->
  <xsl:text>foo element encountered</xsl:text>
</xsl:template>

<xsl:template match="*"> <!-- will be called twice -->
  <xsl:text>other element countered</xsl:text>
</xsl:template>

This way you give up a little control to the XSLT processor - not you decide where the program flow goes, but the processor does by finding the most appropriate match for the node it's currently processing.

If multiple templates can match a node, the one with the more specific match expression wins. If more than one matching template with the same specificity exist, the one declared last wins.

You can concentrate more on developing templates and need less time to do "plumbing". Your programs will become more powerful and modularized, less deeply nested and faster (as XSLT processors are optimized for template matching).

A concept to understand with XSLT is that of the "current node". With <xsl:apply-templates> the current node moves on with every iteration, whereas <xsl:call-template> does not change the current node. I.e. the . within a called template refers to the same node as the . in the calling template. This is not the case with apply-templates.

This is the basic difference. There are some other aspects of templates that affect their behavior: Their mode and priority, the fact that templates can have both a name and a match. It also has an impact whether the template has been imported (<xsl:import>) or not. These are advanced uses and you can deal with them when you get there.

This should work:

DataTable dtTable;

MySQLProcessor.DTTable(mysqlCommand, out dtTable);

// On all tables' rows
foreach (DataRow dtRow in dtTable.Rows)
{
    // On all tables' columns
    foreach(DataColumn dc in dtTable.Columns)
    {
      var field1 = dtRow[dc].ToString();
    }
}

step 1. select * from <tablename>;

step 2. just right click on your output(t.e data) then go to last option export it will give u some extension then click on your required extension then apply u will get new file including data.

You need to change the password directly in the database because at mysql the users and their profiles are saved in the database.

So there are several ways. At phpMyAdmin you simple go to user admin, choose root and change the password.

alter table /** paste the tabal's name **/ add id int IDENTITY(1,1)

delete from /** paste the tabal's name **/ where id in

(

select a.id FROM /** paste the tabal's name / as a LEFT OUTER JOIN ( SELECT MIN(id) as id FROM / paste the tabal's name / GROUP BY / paste the columns c1,c2 .... **/

) as t1 
ON a.id = t1.id

WHERE t1.id IS NULL

)

alter table /** paste the tabal's name **/ DROP COLUMN id

It's not directly possible to reverse sort an array of primitives (i.e., int[] arr = {1, 2, 3};) using Arrays.sort() and Collections.reverseOrder() because those methods require reference types (Integer) instead of primitive types (int).

However, we can use Java 8 Stream to first box the array to sort in reverse order:

// an array of ints
int[] arr = {1, 2, 3, 4, 5, 6};

// an array of reverse sorted ints
int[] arrDesc = Arrays.stream(arr).boxed()
    .sorted(Collections.reverseOrder())
    .mapToInt(Integer::intValue)
    .toArray();

System.out.println(Arrays.toString(arrDesc)); // outputs [6, 5, 4, 3, 2, 1]

Here's what worked for me:

$a = Get-ChildItem \\server\XXX\Received_Orders\*.* | Where{$_.LastWriteTime -ge (Get-Date).AddDays(-7)}
if ($a = (Get-ChildItem \\server\XXX\Received_Orders\*.* | Where{$_.LastWriteTime -gt (Get-Date).AddDays(-7)}  
#Im using the -gt switch instead of -ge
{}
Else
{
'STORE XXX HAS NOT RECEIVED ANY ORDERS IN THE PAST 7 DAYS'
}


$b = Get-ChildItem \\COMP NAME\Folder\*.* | Where{$_.LastWriteTime -ge (Get-Date).AddDays(-1)}
if ($b = (Get-ChildItem \\COMP NAME\TFolder\*.* | Where{$_.LastWriteTime -gt (Get-Date).AddDays(-1)))}
{}
Else
{
'STORE XXX DID NOT RUN ITS BACKUP LAST NIGHT'
}

I am a bit late to the party (by almost 10 years, 2 months), but one way for future coders is to do it using while loop and indexOf()

let haystack = "I learned to play the Ukulele in Lebanon.";
let needle = "le";
let pos = 0; // Position Ref
let result = []; // Final output of all index's.
let hayStackLower = haystack.toLowerCase();

// Loop to check all occurrences 
while (hayStackLower.indexOf(needle, pos) != -1) {
  result.push(hayStackLower.indexOf(needle , pos));
  pos = hayStackLower.indexOf(needle , pos) + 1;
}

console.log("Final ", result); // Returns all indexes or empty array if not found

If you append json data to query string, and parse it later in web api side. you can parse complex object. It's useful rather than post json object style. This is my solution.

//javascript file 
var data = { UserID: "10", UserName: "Long", AppInstanceID: "100", ProcessGUID: "BF1CC2EB-D9BD-45FD-BF87-939DD8FF9071" };
var request = JSON.stringify(data);
request = encodeURIComponent(request);

doAjaxGet("/ProductWebApi/api/Workflow/StartProcess?data=", request, function (result) {
    window.console.log(result);
});

//webapi file:
[HttpGet]
public ResponseResult StartProcess()
{
    dynamic queryJson = ParseHttpGetJson(Request.RequestUri.Query);
        int appInstanceID = int.Parse(queryJson.AppInstanceID.Value);
    Guid processGUID = Guid.Parse(queryJson.ProcessGUID.Value);
    int userID = int.Parse(queryJson.UserID.Value);
    string userName = queryJson.UserName.Value;
}

//utility function:
public static dynamic ParseHttpGetJson(string query)
{
    if (!string.IsNullOrEmpty(query))
    {
        try
        {
            var json = query.Substring(7, query.Length - 7); //seperate ?data= characters
            json = System.Web.HttpUtility.UrlDecode(json);
            dynamic queryJson = JsonConvert.DeserializeObject<dynamic>(json);

            return queryJson;
        }
        catch (System.Exception e)
        {
            throw new ApplicationException("can't deserialize object as wrong string content!", e);
        }
    }
    else
    {
        return null;
    }
}

ng-show and ng-hide work in opposite way. But the difference between ng-hide or ng-show with ng-if is,if we use ng-if then element will created in the dom but with ng-hide/ng-show element will be hidden completely.

ng-show=true/ng-hide=false:
Element will be displayed

ng-show=false/ng-hide=true:
element will be hidden

ng-if =true
element will be created

ng-if= false
element will be created in the dom. 

The concept of NULL is questionable, to say the least. Codd introduced the relational model and the concept of NULL in context (and went on to propose more than one kind of NULL!) However, relational theory has evolved since Codd's original writings: some of his proposals have since been dropped (e.g. primary key) and others never caught on (e.g. theta operators). In modern relational theory (truly relational theory, I should stress) NULL simply does not exist. See The Third Manifesto. http://www.thethirdmanifesto.com/

The SQL language suffers the problem of backwards compatibility. NULL found its way into SQL and we are stuck with it. Arguably, the implementation of NULL in SQL is flawed (SQL Server's implementation makes things even more complicated due to its ANSI_NULLS option).

I recommend avoiding the use of NULLable columns in base tables.

Although perhaps I shouldn't be tempted, I just wanted to assert a corrections of my own about how NULL works in SQL:

NULL = NULL evaluates to UNKNOWN.

UNKNOWN is a logical value.

NULL is a data value.

This is easy to prove e.g.

SELECT NULL = NULL

correctly generates an error in SQL Server. If the result was a data value then we would expect to see NULL, as some answers here (wrongly) suggest we would.

The logical value UNKNOWN is treated differently in SQL DML and SQL DDL respectively.

In SQL DML, UNKNOWN causes rows to be removed from the resultset.

For example:

CREATE TABLE MyTable
(
 key_col INTEGER NOT NULL UNIQUE, 
 data_col INTEGER
 CHECK (data_col = 55)
);

INSERT INTO MyTable (key_col, data_col)
   VALUES (1, NULL);

The INSERT succeeds for this row, even though the CHECK condition resolves to NULL = NULL. This is due defined in the SQL-92 ("ANSI") Standard:

11.6 table constraint definition

3)

If the table constraint is a check constraint definition, then let SC be the search condition immediately contained in the check constraint definition and let T be the table name included in the corresponding table constraint descriptor; the table constraint is not satisfied if and only if

EXISTS ( SELECT * FROM T WHERE NOT ( SC ) )

is true.

Read that again carefully, following the logic.

In plain English, our new row above is given the 'benefit of the doubt' about being UNKNOWN and allowed to pass.

In SQL DML, the rule for the WHERE clause is much easier to follow:

The search condition is applied to each row of T. The result of the where clause is a table of those rows of T for which the result of the search condition is true.

In plain English, rows that evaluate to UNKNOWN are removed from the resultset.

You should use @RequestParam on those resources with method = RequestMethod.GET

In order to post parameters, you must send them as the request body. A body like JSON or another data representation would depending on your implementation (I mean, consume and produce MediaType).

Typically, multipart/form-data is used to upload files.

Looks like there is an entry in the official FAQ for this. The source code is in C but the same principle applies, as outlined here in this mailing list post.

Use cursors.

A cursor can be thought of like a buffered reader, when reading through a document. If you think of each row as a line in a document, then you would read the next line, perform your operations, and then advance the cursor.

DBCC CHECKIDENT(table_name, RESEED, value)

table_name = give the table you want to reset value

value=initial value to be zero,to start identity column with 1

I know the perfect answer:

1. double click on The password TextBox.
2. write your textbox name like textbox2.
3. write PasswordChar = '*';.

4. I prefer going to windows character map and find a perfect hide like ?.

   example:TextBox2.PasswordChar = '?';
   

You can make it a non-submitting button (<button type="button">) and hook something like window.location = 'http://where.you.want/to/go' into its onclick handler. This does not work without javascript enabled though.

Or you can make it a submit button, and do a redirect on the server, although this obviously requires some kind of server-side logic, but the upside is that is doesn't require javascript.

(actually, forget the second solution - if you can't use a form, the submit button is out)

Just add this one line:

    .your-class {
        height: 100vh;
    }

vh is viewport height. This will automatically scale to fit the device' browser window.

Check more here: Make div 100% height of browser window

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

If you decide to use ggplot2, you can set transparency of overlapping points using the alpha argument.

e.g.

library(ggplot2)
ggplot(diamonds, aes(carat, price)) + geom_point(alpha = 1/40)

Another simple way is

transform: scale(1.5);

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

For those who use ASP.NET Identity 2.1 and have changed the primary key from the default string to either int or Guid, if you're still getting

EntityType 'xxxxUserLogin' has no key defined. Define the key for this EntityType.

EntityType 'xxxxUserRole' has no key defined. Define the key for this EntityType.

you probably just forgot to specify the new key type on IdentityDbContext:

public class AppIdentityDbContext : IdentityDbContext<
    AppUser, AppRole, int, AppUserLogin, AppUserRole, AppUserClaim>
{
    public AppIdentityDbContext()
        : base("MY_CONNECTION_STRING")
    {
    }
    ......
}

If you just have

public class AppIdentityDbContext : IdentityDbContext
{
    ......
}

or even

public class AppIdentityDbContext : IdentityDbContext<AppUser>
{
    ......
}

you will get that 'no key defined' error when you are trying to add migrations or update the database.

if ( $("#txt").val().length == 0 )
{
  // do something
}

I had to add in the == to get it to work for me, otherwise it ignored the condition even with empty text input. May help someone.

Follow these steps with Notepad++

1- Copy the original text

2- In Notepad++, open new file, change Encoding -> pick an encoding you think the original text follows. Try as well the encoding "ANSI" as sometimes Unicode files are read as ANSI by certain programs

3- Paste

4- Then to convert to Unicode by going again over the same menu: Encoding -> "Encode in UTF-8" (Not "Convert to UTF-8") and hopefully it will become readable

The above steps apply for most languages. You just need to guess the original encoding before pasting in notepad++, then convert through the same menu to an alternate Unicode-based encoding to see if things become readable.

Most languages exist in 2 forms of encoding: 1- The old legacy ANSI (ASCII) form, only 8 bits, was used initially by most computers. 8 bits only allowed 256 possibilities, 128 of them where the regular latin and control characters, the final 128 bits were read differently depending on the PC language settings 2- The new Unicode standard (up to 32 bit) give a unique code for each character in all currently known languages and plenty more to come. if a file is unicode it should be understood on any PC with the language's font installed. Note that even UTF-8 goes up to 32 bit and is just as broad as UTF-16 and UTF-32 only it tries to stay 8 bits with latin characters just to save up disk space

The emulator does not provide virtual hardware for Wi-Fi if you use API 24 or earlier. From the Android Developers website:

When using an AVD with API level 25 or higher, the emulator provides a simulated Wi-Fi access point ("AndroidWifi"), and Android automatically connects to it.

You can disable Wi-Fi in the emulator by running the emulator with the command-line parameter -feature -Wifi.

https://developer.android.com/studio/run/emulator.html#wi-fi

What's not supported

The Android Emulator doesn't include virtual hardware for the following:

• Bluetooth
• NFC
• SD card insert/eject
• Device-attached headphones
• USB

The watch emulator for Android Wear doesn't support the Overview (Recent Apps) button, D-pad, and fingerprint sensor.

If you are using C function fgetc then you should check a next character whether it is equal to the new line character or to EOF. For example

unsigned int count = 0;
while ( 1 )
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
      if ( c == EOF ) break;
   }
   else
   {
      ++count;
   }
}    

or maybe it would be better to rewrite the code using do-while loop. For example

unsigned int count = 0;
do
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
   }
   else
   {
      ++count;
   }
} while ( c != EOF );

Of course you need to insert your own processing of read xgaracters. It is only an example how you could use function fgetc to read lines of a file.

But if the program is written in C++ then it would be much better if you would use std::ifstream and std::string classes and function std::getline to read a whole line.

Add double quotes to use caret operator in version number.

Just for kicks, here's the functions I wrote to do it before I had the .PadRight bit:

    public string insertSpacesAtEnd(string input, int longest)
    {
        string output = input;
        string spaces = "";
        int inputLength = input.Length;
        int numToInsert = longest - inputLength;

        for (int i = 0; i < numToInsert; i++)
        {
            spaces += " ";
        }

        output += spaces;

        return output;
    }

    public int findLongest(List<Results> theList)
    {
        int longest = 0;

        for (int i = 0; i < theList.Count; i++)
        {
            if (longest < theList[i].title.Length)
                longest = theList[i].title.Length;
        }
        return longest;
    }

    ////Usage////
    for (int i = 0; i < storageList.Count; i++)
    {
        output += insertSpacesAtEnd(storageList[i].title, longest + 5) +   storageList[i].rank.Trim() + "     " + storageList[i].term.Trim() + "         " + storageList[i].name + "\r\n";
    }

To update a subset of fields, you can use update_fields:

survey.save(update_fields=["active"]) 

The update_fields argument was added in Django 1.5. In earlier versions, you could use the update() method instead:

Survey.objects.filter(pk=survey.pk).update(active=True)

Say your model is 'Shop'

class Shop(models.Model):
    street = models.CharField(max_length=150)
    city = models.CharField(max_length=150)

    # some of your models may have explicit ordering
    class Meta:
        ordering = ('city')

Since you may have the Meta class ordering attribute set, you can use order_by() without parameters to clear any ordering when using distinct(). See the documentation under order_by()

If you don’t want any ordering to be applied to a query, not even the default ordering, call order_by() with no parameters.

and distinct() in the note where it discusses issues with using distinct() with ordering.

To query your DB, you just have to call:

models.Shop.objects.order_by().values('city').distinct()

It returns a dictionnary

or

models.Shop.objects.order_by().values_list('city').distinct()

This one returns a ValuesListQuerySet which you can cast to a list. You can also add flat=True to values_list to flatten the results.

See also: Get distinct values of Queryset by field

If the other answers fail, importing it as

import moment from 'moment/moment.js'

may work.

I've used XDocument.Root.Add to add elements. Root returns XElement which has an Add function for additional XElements

Try this snippet:

function stripAndExecuteScript(text) {
    var scripts = '';
    var cleaned = text.replace(/<script[^>]*>([\s\S]*?)<\/script>/gi, function(){
        scripts += arguments[1] + '\n';
        return '';
    });

    if (window.execScript){
        window.execScript(scripts);
    } else {
        var head = document.getElementsByTagName('head')[0];
        var scriptElement = document.createElement('script');
        scriptElement.setAttribute('type', 'text/javascript');
        scriptElement.innerText = scripts;
        head.appendChild(scriptElement);
        head.removeChild(scriptElement);
    }
    return cleaned;
};


var scriptString = '<scrip' + 't + type="text/javascript">alert(\'test\');</scr' + 'ipt><strong>test</strong>';
document.getElementById('element').innerHTML = stripAndExecuteScript(scriptString);

It's unclear how you want to handle fractional years, but perhaps like this:

DateTime now = DateTime.Now;
DateTime origin = new DateTime(2007, 11, 3);
int calendar_years = now.Year - origin.Year;
int whole_years = calendar_years - ((now.AddYears(-calendar_years) >= origin)? 0: 1);
int another_method = calendar_years - ((now.Month - origin.Month) * 32 >= origin.Day - now.Day)? 0: 1);

Try this:

$('#parent').on('click', '#child', function() {
    // Code
});

From the $.on() documentation:

Event handlers are bound only to the currently selected elements; they must exist on the page at the time your code makes the call to .on().

Your #child element doesn't exist when you call $.on() on it, so the event isn't bound (unlike $.live()). #parent, however, does exist, so binding the event to that is fine.

The second argument in my code above acts as a 'filter' to only trigger if the event bubbled up to #parent from #child.

You should use let keyword as to declare local variables e.g *ngFor="let talk of talks"

You can use Linq to cleverly initialize your list with a default value. (Similar to David B's answer.)

var defaultStrings = (new int[10]).Select(x => "my value").ToList();

Go one step farther and initialize each string with distinct values "string 1", "string 2", "string 3", etc:

int x = 1;
var numberedStrings = (new int[10]).Select(x => "string " + x++).ToList();

    public static void main(String[] args) {

            for(int i=0;i<3;i++){
                String s1=sc.next();
                int x=sc.nextInt();
                System.out.println(String.format("%-15s%03d",s1,x));
            }
            System.out.println("================================");

    }
}

Java solution

• The "-" is used to left indent

• The "15" makes the String's minimum length it takes up be 15

• The "s" (which is a few characters after %) will be substituted by our String
• The 0 pads our integer with 0s on the left
• The 3 makes our integer be a minimum length of 3

Although solution to this problem is hardly coded in regeneration of your .htaccess file; indeed it din't worked for most of you specially when the site is migrated to some new server.

Let's dive into some basics.

Let's assume that for most of us, WordPress environment is running on a PHP server APACHE where this server is controlling most of our environment's initial dependencies. Meanwhile .htaccess generation is also mainly dependent on Apache configurations.

So if that been said, the contribution of .htaccess creation conflict mainly occurs when a WordPress website is migrated from a server running the WordPress environment on old version of Apache and PHP to a newer version of PHP and Apache.

Because dependencies of nrwer and older versions are different that's why the newer version of Apache2 won't allow the .htaccess directives to create a .htaccess file by default; because of which we have to manually set the WordPress website's root directory permissions from "AllowOverride None" to "AllowOverride All".

Comparatively, AllowOverride directive is used to allow the use of .htaccess within the web server to allow overriding of the Apache config on a per directory basis.

Use the following fix to change the apache2.conf directory permission settings:

To define Optional Protocol in swift you should use @objc keyword before Protocol declaration and attribute/method declaration inside that protocol. Below is a sample of Optional Property of a protocol.

@objc protocol Protocol {

  @objc optional var name:String?

}

class MyClass: Protocol {

   // No error

}

Do you mean something like this:

s1 = '00000001'
s2 = '11111110'
int(s1,2) ^ int(s2,2)

Boost has something to help: the Boost.Iterator library.

More precisely this page: boost::iterator_adaptor.

What's very interesting is the Tutorial Example which shows a complete implementation, from scratch, for a custom type.

template <class Value>
class node_iter
  : public boost::iterator_adaptor<
        node_iter<Value>                // Derived
      , Value*                          // Base
      , boost::use_default              // Value
      , boost::forward_traversal_tag    // CategoryOrTraversal
    >
{
 private:
    struct enabler {};  // a private type avoids misuse

 public:
    node_iter()
      : node_iter::iterator_adaptor_(0) {}

    explicit node_iter(Value* p)
      : node_iter::iterator_adaptor_(p) {}

    // iterator convertible to const_iterator, not vice-versa
    template <class OtherValue>
    node_iter(
        node_iter<OtherValue> const& other
      , typename boost::enable_if<
            boost::is_convertible<OtherValue*,Value*>
          , enabler
        >::type = enabler()
    )
      : node_iter::iterator_adaptor_(other.base()) {}

 private:
    friend class boost::iterator_core_access;
    void increment() { this->base_reference() = this->base()->next(); }
};

The main point, as has been cited already, is to use a single template implementation and typedef it.

                begin
                    Set @OpenQty=0
                end
            else
                begin
                   Select   @OpenQty=IsNull(Sum(ClosingQty),0)  
                   From  ProductAndDepotWiseMonitoring  
                   Where   Pcd=@PCd And PtpCd=@PTpCd And TransDt=@LstTransDt      
                end 

See if this helps.

You are replacing the starting tag and then putting that back in innerHTML, so the code will be invalid. Make all the replacements before you put the code back in the element:

var html = strMessage1.innerHTML;
html = html.replace( /aaaaaa./g,'<a href=\"http://www.google.com/');
html = html.replace( /.bbbbbb/g,'/world\">Helloworld</a>');
strMessage1.innerHTML = html;

I'm quite late to the party, but one approach is to use a static inner class to unwrap values:

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

class Scratch {
    private final String aString;
    private final String bString;
    private final String cString;
    private final static String jsonString;

    static {
        jsonString = "{\n" +
                "  \"wrap\" : {\n" +
                "    \"A\": \"foo\",\n" +
                "    \"B\": \"bar\",\n" +
                "    \"C\": \"baz\"\n" +
                "  }\n" +
                "}";
    }

    @JsonCreator
    Scratch(@JsonProperty("A") String aString,
            @JsonProperty("B") String bString,
            @JsonProperty("C") String cString) {
        this.aString = aString;
        this.bString = bString;
        this.cString = cString;
    }

    @Override
    public String toString() {
        return "Scratch{" +
                "aString='" + aString + '\'' +
                ", bString='" + bString + '\'' +
                ", cString='" + cString + '\'' +
                '}';
    }

    public static class JsonDeserializer {
        private final Scratch scratch;

        @JsonCreator
        public JsonDeserializer(@JsonProperty("wrap") Scratch scratch) {
            this.scratch = scratch;
        }

        public Scratch getScratch() {
            return scratch;
        }
    }

    public static void main(String[] args) throws JsonProcessingException {
        ObjectMapper objectMapper = new ObjectMapper();
        Scratch scratch = objectMapper.readValue(jsonString, Scratch.JsonDeserializer.class).getScratch();
        System.out.println(scratch.toString());
    }
}

However, it's probably easier to use objectMapper.configure(SerializationConfig.Feature.UNWRAP_ROOT_VALUE, true); in conjunction with @JsonRootName("aName"), as pointed out by pb2q

My take is a combination of a couple of posted answers, with some modifications to make them easier to use from within a running python environment.

The idea is to provide a entirely new command (modeled after the install command) that gives you an instance of the package finder to use. The upside is that it works with, and uses, any indexes that pip supports and reads your local pip configuration files, so you get the correct results as you would with a normal pip install.

I've made an attempt at making it compatible with both pip v 9.x and 10.x.. but only tried it on 9.x

If you just want to check the type, you can use jQuery's .is() function,

Like in my case I used below,

if($("#id").is("select")) {
 alert('Select'); 
else if($("#id").is("input")) {
 alert("input");
}

Use ==:

pip install django_modeltranslation==0.4.0-beta2

1.Use git reflog to get all references update.

2.git reset <id_of_commit_to_which_you_want_restore>

declare @ModelID uniqueidentifer

--make sure to use brackets
set @ModelID = (select modelid from models
where areaid = 'South Coast')

select @ModelID

Make sure your code is in DOM Ready as pointed by rocket-hazmat

.click()

$('#RootNode').click(function(){
  //do something
});

document.getElementById("RootNode").onclick = function(){//do something}

Use event Delegation/

$(document).on("click", "#RootNode", function(){
   //do something
});

Wrap Code in Dom Ready

$(document).ready(function(){
    $('#RootNode').click(function(){
     //do something
    });
});

You can get all the required file properties by using the code below:

FOR %%? IN (file_to_be_queried) DO (
    ECHO File Name Only       : %%~n?
    ECHO File Extension       : %%~x?
    ECHO Name in 8.3 notation : %%~sn?
    ECHO File Attributes      : %%~a?
    ECHO Located on Drive     : %%~d?
    ECHO File Size            : %%~z?
    ECHO Last-Modified Date   : %%~t?
    ECHO Parent Folder        : %%~dp?
    ECHO Fully Qualified Path : %%~f?
    ECHO FQP in 8.3 notation  : %%~sf?
    ECHO Location in the PATH : %%~dp$PATH:?
)

Up until jQuery 1.11.1, you could use the following URLs to get the latest version of jQuery:

• https://code.jquery.com/jquery-latest.min.js - jQuery hosted (minified)
• https://code.jquery.com/jquery-latest.js - jQuery hosted (uncompressed)
• https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js - Google hosted (minified)
• https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js - Google hosted (uncompressed)

For example:

<script src="https://code.jquery.com/jquery-latest.min.js"></script>

However, since jQuery 1.11.1, both jQuery and Google stopped updating these URL's; they will forever be fixed at 1.11.1. There is no supported alternative URL to use. For an explanation of why this is the case, see this blog post; Don't use jquery-latest.js.

Both hosts support https as well as http, so change the protocol as you see fit (or use a protocol relative URI)

In full generality, this functionality is impossible. The Java ClassLoader mechanism guarantees only the ability to ask for a class with a specific name (including pacakge), and the ClassLoader can supply a class, or it can state that it does not know that class.

Classes can be (and frequently are) loaded from remote servers, and they can even be constructed on the fly; it is not difficult at all to write a ClassLoader that returns a valid class that implements a given interface for any name you ask from it; a List of the classes that implement that interface would then be infinite in length.

In practice, the most common case is an URLClassLoader that looks for classes in a list of filesystem directories and JAR files. So what you need is to get the URLClassLoader, then iterate through those directories and archives, and for each class file you find in them, request the corresponding Class object and look through the return of its getInterfaces() method.

Although this shouldn't be a real solution, it does work locally if you are stuck

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '';

Visibility change itself can be easy animated by overriding setVisibility method. Look at complete code:

public class SimpleViewAnimator extends FrameLayout
{
    private Animation inAnimation;
    private Animation outAnimation;

    public SimpleViewAnimator(Context context)
    {
        super(context);
    }

    public void setInAnimation(Animation inAnimation)
    {
        this.inAnimation = inAnimation;
    }

    public void setOutAnimation(Animation outAnimation)
    {
        this.outAnimation = outAnimation;
    }

    @Override
    public void setVisibility(int visibility)
    {
        if (getVisibility() != visibility)
        {
            if (visibility == VISIBLE)
            {
                if (inAnimation != null) startAnimation(inAnimation);
            }
            else if ((visibility == INVISIBLE) || (visibility == GONE))
            {
                if (outAnimation != null) startAnimation(outAnimation);
            }
        }

        super.setVisibility(visibility);
    }
}

My autocomplete also didn't work because Visual Studio Tools for Unity wasn't installed. So, after you install that, delete the auto generated Visual Studio files. Others said that you open file again and the problem is solved but it's not.

The trick is: instead of normally double-clicking the file, you need to open the C# file from Unity by right click and then "Open C# Project".

Because you have this:

Blowfish(BlowfishAlgorithm algorithm);

It's not a default constructor. The default constructor is one which takes no parameters. i.e.

Blowfish();

You can use a try-except

try:
   print(str.to.id)
except AttributeError: # Not a Retweet
   print('null')

There are two cases in which you might want to clear a list:

1. You want to use the name old_list further in your code;
2. You want the old list to be garbage collected as soon as possible to free some memory;

In case 1 you just go on with the assigment:

    old_list = []    # or whatever you want it to be equal to

In case 2 the del statement would reduce the reference count to the list object the name old list points at. If the list object is only pointed by the name old_list at, the reference count would be 0, and the object would be freed for garbage collection.

    del old_list

It depends on what you want the behaviour to be. An int cannot hold many of the values that an unsigned int can.

You can cast as usual:

int signedInt = (int) myUnsigned;

but this will cause problems if the unsigned value is past the max int can hold. This means half of the possible unsigned values will result in erroneous behaviour unless you specifically watch out for it.

You should probably reexamine how you store values in the first place if you're having to convert for no good reason.

EDIT: As mentioned by ProdigySim in the comments, the maximum value is platform dependent. But you can access it with INT_MAX and UINT_MAX.

For the usual 4-byte types:

4 bytes = (4*8) bits = 32 bits

If all 32 bits are used, as in unsigned, the maximum value will be 2^32 - 1, or 4,294,967,295.

A signed int effectively sacrifices one bit for the sign, so the maximum value will be 2^31 - 1, or 2,147,483,647. Note that this is half of the other value.

Update April 2013: Don't do this. It wasn't a good idea in 2009 when I first answered the question and it really isn't a good idea now. See this answer by hackbod for reasons:

Avoid reloading activity with asynctask on orientation change in android

Add android:configChanges="keyboardHidden|orientation" to your AndroidManifest.xml. This tells the system what configuration changes you are going to handle yourself - in this case by doing nothing.

<activity android:name="MainActivity"
     android:screenOrientation="portrait"
     android:configChanges="keyboardHidden|orientation">

See Developer reference configChanges for more details.

However, your application can be interrupted at any time, e.g. by a phone call, so you really should add code to save the state of your application when it is paused.

Update: As of Android 3.2, you also need to add "screenSize":

<activity
    android:name="MainActivity"
    android:screenOrientation="portrait"
    android:configChanges="keyboardHidden|orientation|screenSize">

From Developer guide Handling the Configuration Change Yourself

Caution: Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), you must include the "screenSize" value in addition to the "orientation" value. That is, you must declare android:configChanges="orientation|screenSize". However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device).

The following is what I want.

Test Data

class Base:
    b = 'b'


class MyClass(Base):
    a = '12'

    def __init__(self, name):
        self.name = name

    @classmethod
    def c(cls):
        ...

    @property
    def p(self):
        return self.a

    def my_fun(self):
        return self.name

print([name for name, val in inspect.getmembers(MyClass) if not name.startswith('_') and not callable(val)])  # need `import inspect`
print([_ for _ in dir(MyClass) if not _.startswith('_') and not callable(getattr(MyClass, _))])
# both are equ: ['a', 'b', 'p']

my_instance = MyClass('c')
print([_ for _ in dir(my_instance) if not _.startswith('_') and not callable(getattr(my_instance, _))])
# ['a', 'b', 'name', 'p']

I was working also on web scraping project and same issue found, below code applied and it worked nicely. If you are not aware about TLS versions then you can apply all below otherwise you can apply specific.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11;

I've used min-height: 100vh; with great success on some of my projects. See example.

More one tip very simple. You also could use to_char function, look:

For Month:

to_char(happened_at , 'MM') = 01

to_char(happened_at , 'YYYY') = 2009

to_char(happened_at , 'DD') = 01

to_char funcion is suported by sql language and not by one specific database.

I hope help anybody more...

Abs!

++i (Prefix operation): Increments and then assigns the value
(eg): int i = 5, int b = ++i In this case, 6 is assigned to b first and then increments to 7 and so on.

i++ (Postfix operation): Assigns and then increments the value
(eg): int i = 5, int b = i++ In this case, 5 is assigned to b first and then increments to 6 and so on.

Incase of for loop: i++ is mostly used because, normally we use the starting value of i before incrementing in for loop. But depending on your program logic it may vary.

As has been said, using unset is different with arrays as well

$ foo=(4 5 6)

$ foo[2]=

$ echo ${#foo[*]}
3

$ unset foo[2]

$ echo ${#foo[*]}
2

I had missing application context in the Tomcat Run\Debug configuration:

Adding it, solved the problem and I got the right response instead of "The origin server did not find..."

I can think of at least two situations where you would want to have multiple .gitignore files in different (sub)directories.

• Different directories have different types of file to ignore. For example the .gitignore in the top directory of your project ignores generated programs, while Documentation/.gitignore ignores generated documentation.

• Ignore given files only in given (sub)directory (you can use /sub/foo in .gitignore, though).

Please remember that patterns in .gitignore file apply recursively to the (sub)directory the file is in and all its subdirectories, unless pattern contains '/' (so e.g. pattern name applies to any file named name in given directory and all its subdirectories, while /name applies to file with this name only in given directory).

To avoid reinit(affect performance) of prefix use TextUtils.isEmpty:

            String prefix = "";
            for (String item : list) {
                sb.append(prefix);
                if (TextUtils.isEmpty(prefix))
                    prefix = ",";
                sb.append(item);
            }

Many thanks for the information about using the QueryDefs collection! I have been wondering about this for a while.

I did it a different way, without using VBA, by using a table containing the query parameters.

E.g:

SELECT a_table.a_field 
FROM QueryParameters, a_table 
WHERE a_table.a_field BETWEEN QueryParameters.a_field_min 
AND QueryParameters.a_field_max

Where QueryParameters is a table with two fields, a_field_min and a_field_max

It can even be used with GROUP BY, if you include the query parameter fields in the GROUP BY clause, and the FIRST operator on the parameter fields in the HAVING clause.

Had the same problem. found some videos on Youtube. So here is an even simpler suggestion. This is all the code you need:

#include <QDebug>

int main(int argc, char *argv[])  
{
   qDebug() <<"Hello World"<< endl;
   return 0;
}

The above code comes from Qt5 Tutorial: Building a simple Console application by

If you want to extract structured data from Wikipedia, you may consider using DbPedia http://dbpedia.org/

It provides means to query data using given criteria using SPARQL and returns data from parsed Wikipedia infobox templates

Here is a quick example how it could be done in .NET http://www.kozlenko.info/blog/2010/07/20/executing-sparql-query-on-wikipedia-in-net/

There are some SPARQL libraries available for multiple platforms to make queries easier

I have replaced the printf calls with calls to warning in the C-code now. It will be effective in the version 2.17.2 which should be available tomorrow night. Then you should be able to avoid the warnings with suppressWarnings() or any of the other above mentioned methods.

suppressWarnings({ your code })

To see list of all packages that are installed.

$ npm ls --parseable | awk '{gsub(/\/.*\//,"",$1); print}'| sort -u

show parseable of npm packages list https://docs.npmjs.com/cli/ls#parseable

You are printing the wrong value. Instead if the string you print the scanners object. Try this

Scanner input = new Scanner(System.in);
String s = input.next();
System.out.println(s);

make in, and off itself, handles directory targets just the same as file targets. So, it's easy to write rules like this:

outDir/someTarget: Makefile outDir
    touch outDir/someTarget

outDir:
    mkdir -p outDir

The only problem with that is, that the directories timestamp depends on what is done to the files inside. For the rules above, this leads to the following result:

$ make
mkdir -p outDir
touch outDir/someTarget
$ make
touch outDir/someTarget
$ make
touch outDir/someTarget
$ make
touch outDir/someTarget

This is most definitely not what you want. Whenever you touch the file, you also touch the directory. And since the file depends on the directory, the file consequently appears to be out of date, forcing it to be rebuilt.

However, you can easily break this loop by telling make to ignore the timestamp of the directory. This is done by declaring the directory as an order-only prerequsite:

# The pipe symbol tells make that the following prerequisites are order-only
#                           |
#                           v
outDir/someTarget: Makefile | outDir
    touch outDir/someTarget

outDir:
    mkdir -p outDir

This correctly yields:

$ make
mkdir -p outDir
touch outDir/someTarget
$ make
make: 'outDir/someTarget' is up to date.

TL;DR:

Write a rule to create the directory:

$(OUT_DIR):
    mkdir -p $(OUT_DIR)

And have the targets for the stuff inside depend on the directory order-only:

$(OUT_DIR)/someTarget: ... | $(OUT_DIR)

2014 and above at least you can set a default and it will take that and NOT error when you do not pass that parameter. Partial Example: the 3rd parameter is added as optional. exec of the actual procedure with only the first two parameters worked fine

exec getlist 47,1,0

create procedure getlist
   @convId int,
   @SortOrder int,
   @contestantsOnly bit = 0
as

Check out this snippet:

Private Sub openDialog()
    Dim fd As Office.FileDialog

    Set fd = Application.FileDialog(msoFileDialogFilePicker)

   With fd

      .AllowMultiSelect = False

      ' Set the title of the dialog box.
      .Title = "Please select the file."

      ' Clear out the current filters, and add our own.
      .Filters.Clear
      .Filters.Add "Excel 2003", "*.xls"
      .Filters.Add "All Files", "*.*"

      ' Show the dialog box. If the .Show method returns True, the
      ' user picked at least one file. If the .Show method returns
      ' False, the user clicked Cancel.
      If .Show = True Then
        txtFileName = .SelectedItems(1) 'replace txtFileName with your textbox

      End If
   End With
End Sub

I think this is what you are asking for.

You can also use the sqldf package which performs selects on R data frames as :

df1 <- sqldf("select A, B, E from df")

This gives as the output a data frame df1 with columns: A, B ,E.

for me "1.0" didn't work, but '0' worked. This is Python 2.7.12, just FYI. Also depends on how you import the module. Here's how:

import Tkinter as tk
window = tk.Tk()
textBox = tk.Entry(window)
textBox.pack()

And the following code is called when you need to clear it. In my case there was a button Save that saves the data from the Entry text box and after the button is clicked, the text box is cleared

textBox.delete('0',tk.END)

I know this is really old, but I'm posting my solution anyways since google finds this thread.

background-image: url('./imagefolder/image.jpg');

That is what I do. Two dots means drill back one directory closer to root ".." while one "." should mean start where you are at as if it were root. I was having similar issues but adding that fixed it for me. You can even leave the "." in it when uploading to your host because it should work fine so long as your directory setup is exactly the same.

I like the answers for this question. But to be creative, I would like to share one more way:

<script>if (document.URL.substring(0,5) == "http:") window.location.replace('https:' + document.URL.substring(5));</script>

$scope.actions.data.concat is not a function 

same problem with me but i solve the problem by

 $scope.actions.data = [].concat($scope.actions.data , data)

You definitely can achieve that with nbconvert using the following command:

jupyter nbconvert --to python while.ipynb 

However, having used it personally I would advise against it for several reasons:

1. It's one thing to be able to convert to simple Python code and another to have all the right abstractions, classes access and methods set up. If the whole point of you converting your notebook code to Python is getting to a state where your code and notebooks are maintainable for the long run, then nbconvert alone will not suffice. The only way to do that is by manually going through the codebase.
2. Notebooks inherently promote writing code which is not maintainable (https://docs.google.com/presentation/d/1n2RlMdmv1p25Xy5thJUhkKGvjtV-dkAIsUXP-AL4ffI/edit#slide=id.g3d7fe085e7_0_21). Using nbconvert on top might just prove to be a bandaid. Specific examples of where it promotes not-so-maintainable code are imports might be sprayed throughout, hard coded paths are not in one simple place to view, class abstractions might not be present, etc.
3. nbconvert still mixes execution code and library code.
4. Comments are still not present (probably were not in the notebook).
5. There is still a lack of unit tests etc.

So to summarize, there is not good way to out of the box convert python notebooks to maintainable, robust python modularized code, the only way is to manually do surgery.

Have you looked into rasdial?

Just incase anyone wanted to do this and finds this in the future, you can use rasdial.exe from command prompt to connect to a VPN network

ie rasdial "VPN NETWORK NAME" "Username" *

it will then prompt for a password, else you can use "username" "password", this is however less secure

If you're using at least Java 8, see my other answer.

If you're already using Google Guava, see Sean Patrick Floyd's answer.

If you're stuck at Java 7 and don't want to include Google Guava, you can write your own (read-only) Iterables.concat() using no more than Iterable and Iterator:

Constant number

public static <E> Iterable<E> concat(final Iterable<? extends E> iterable1,
                                     final Iterable<? extends E> iterable2) {
    return new Iterable<E>() {
        @Override
        public Iterator<E> iterator() {
            return new Iterator<E>() {
                final Iterator<? extends E> iterator1 = iterable1.iterator();
                final Iterator<? extends E> iterator2 = iterable2.iterator();

                @Override
                public boolean hasNext() {
                    return iterator1.hasNext() || iterator2.hasNext();
                }

                @Override
                public E next() {
                    return iterator1.hasNext() ? iterator1.next() : iterator2.next();
                }
            };
        }
    };
}

Variable number

@SafeVarargs
public static <E> Iterable<E> concat(final Iterable<? extends E>... iterables) {
    return concat(Arrays.asList(iterables));
}

public static <E> Iterable<E> concat(final Iterable<Iterable<? extends E>> iterables) {
    return new Iterable<E>() {
        final Iterator<Iterable<? extends E>> iterablesIterator = iterables.iterator();

        @Override
        public Iterator<E> iterator() {
            return !iterablesIterator.hasNext() ? Collections.emptyIterator()
                                                : new Iterator<E>() {
                Iterator<? extends E> iterableIterator = nextIterator();

                @Override
                public boolean hasNext() {
                    return iterableIterator.hasNext();
                }

                @Override
                public E next() {
                    final E next = iterableIterator.next();
                    findNext();
                    return next;
                }

                Iterator<? extends E> nextIterator() {
                    return iterablesIterator.next().iterator();
                }

                Iterator<E> findNext() {
                    while (!iterableIterator.hasNext()) {
                        if (!iterablesIterator.hasNext()) {
                            break;
                        }
                        iterableIterator = nextIterator();
                    }
                    return this;
                }
            }.findNext();
        }
    };
}

To read more than one json tip (array, attribute) I did the following.

var jVariable = JsonConvert.DeserializeObject<YourCommentaryClass>(jsonVariableContent);

change to

var jVariable = JsonConvert.DeserializeObject <List<YourCommentaryClass>>(jsonVariableContent);

Because you cannot see all the bits in the method used in the foreach loop. Example foreach loop

foreach (jsonDonanimSimple Variable in jVariable)
                {    
                    debugOutput(jVariable.Id.ToString());
                    debugOutput(jVariable.Header.ToString());
                    debugOutput(jVariable.Content.ToString());
                }

I also received an error in this loop and changed it as follows.

foreach (jsonDonanimSimple Variable in jVariable)
                    {    
                        debugOutput(Variable.Id.ToString());
                        debugOutput(Variable.Header.ToString());
                        debugOutput(Variable.Content.ToString());
                    }

Try this

$('#myModal').on('shown.bs.modal', function () {
   alert('hi');
});

Using shown instead of show also make sure you have your semi colons at the end of your function and alert.

If you're using ASP.NET MVC you might also need to remove the HandleErrorAttribute from the Global.asax.cs file:

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
    filters.Add(new HandleErrorAttribute());
}

Easiest solution:

plot([0,0],[0.0], xData, yData);

This creates an invisible line between the points [0,0] to [0,0] and since Matlab wants to include these points it will shows the axis.

I would avoid to do a query for each entry.

if(is_array($EMailArr)){

    $sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) values ";

    $valuesArr = array();
    foreach($EMailArr as $row){

        $R_ID = (int) $row['R_ID'];
        $email = mysql_real_escape_string( $row['email'] );
        $name = mysql_real_escape_string( $row['name'] );

        $valuesArr[] = "('$R_ID', '$email', '$name')";
    }

    $sql .= implode(',', $valuesArr);

    mysql_query($sql) or exit(mysql_error()); 
}

$().live(function(){}); and jQuery.browser is undefined in jquery 1.9.0 - $.browser was deprecated in jquery update

sounds like you are using a different version of jquery 1.9 in godaddy so either change your code or include the migrate plugin http://code.jquery.com/jquery-migrate-1.0.0.js

color and fill are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:

d + scale_color_manual(values=c("#CC6666", "#9999CC"))

is what you want.

Javascript arrays have a length property. Use it like this:

st.itemb.length

Let's try this way:

select 
    a.ip, 
    a.os, 
    a.hostname, 
    a.port, 
    a.protocol, 
    b.state
from a
left join b 
    on a.ip = b.ip 
        and a.port = b.port /*if you has to filter by columns from right table , then add this condition in ON clause*/
where a.somecolumn = somevalue /*if you have to filter by some column from left table, then add it to where condition*/

So, in where clause you can filter result set by column from right table only on this way:

...
where b.somecolumn <> (=) null

There is also a compact form for that, if you do not want to rely on strlen. Assuming that the character array you are considering is "msg":

  unsigned int len=0;
  while(*(msg+len) ) len++;

I'm adding up to the original answer given by Guy which is still valid today (soon 2020).

Overriding the default docker registry, like you would do with maven, is actually not a good practice.

When using maven, you pull artifacts from Maven Central Repository through your local repository management system that will act as a proxy. These artifacts are plain, raw libs (jars) and it is quite unlikely that you will push jars with the same name.

On the other hand, docker images are fully operational, runnable, environments, and it makes total sens to pull an image from the Docker Hub, modify it and push this image in your local registry management system with the same name, because it is exactly what its name says it is, just in your enterprise context. In this case, the only distinction between the two images would precisely be its path!!

Therefore the need to set the following rule: the prefix of an image indicates its origin; by default if an image does not have a prefix, it is pulled from Docker Hub.

The easiest way to determine the size and position of an element is to call its getBoundingClientRect() method. This method returns element positions in viewport coordinates. It expects no arguments and returns an object with properties left, right, top, and bottom. The left and top properties give the X and Y coordinates of the upper-left corner of the element and the right and bottom properties give the coordinates of the lower-right corner.

element.getBoundingClientRect(); // Get position in viewport coordinates

Supported everywhere.

sp_who2 'active'

Check values under CPUTime and DiskIO. Note the SPID of process having large value comparatively.

kill {SPID value}

The simplest is to call stop propagation on an event handler. $event works the same in Angular 2, and contains the ongoing event (by it a mouse click, mouse event, etc.):

(click)="onEvent($event)"

on the event handler, we can there stop the propagation:

onEvent(event) {
   event.stopPropagation();
}

With ES6:

function test(a, b = 3) {
   console.log(a, ' ', b);
}

test(1);      // Output: 1 3
test(1, 2);   // Output: 1 2

Use:

svn copy http://svn.example.com/project/trunk \
      http://svn.example.com/project/tags/1.0 -m "Release 1.0"

Shorthand:

cd /path/to/project
svn copy ^/trunk ^/tags/1.0 -m "Release 1.0"

I keep hitting this answer. But none of them list the easiest solution for xsltproc (and probably most XSLT 1.0 processors):

1. Add the exslt strings name to the stylesheet, i.e.:

<xsl:stylesheet
  version="1.0"
  xmlns:str="http://exslt.org/strings"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

2. Then use it like:

<xsl:value-of select="str:replace(., ' ', '')"/>

Is this what you're looking for?

if (request instanceof HttpServletRequest) {
 String url = ((HttpServletRequest)request).getRequestURL().toString();
 String queryString = ((HttpServletRequest)request).getQueryString();
}

To Reconstruct:

System.out.println(url + "?" + queryString);

Info on HttpServletRequest.getRequestURL() and HttpServletRequest.getQueryString().

ASP.NET web forms page already have a JavaScript method for handling PostBacks called "__doPostBack".

function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}

Use the following in your code file to generate the JavaScript that performs the PostBack. Using this method will ensure that the proper ClientID for the control is used.

protected string GetLoginPostBack()
{
    return Page.ClientScript.GetPostBackEventReference(btnLogin, string.Empty);
}

Then in the ASPX page add a javascript block.

<script language="javascript">
function btnLogin_Click() {
  <%= GetLoginPostBack() %>;
}
</script>

The final javascript will be rendered like this.

<script language="javascript">
function btnLogin_Click() {
  __doPostBack('btnLogin','');
}
</script>

Now you can use "btnLogin_Click()" from your javascript to submit the button click to the server.

I ran into this issue when I wanted to temporarily disable the sending of an email while working on another part of the code.

Commenting the use of the service triggered a lot of cascade errors, so instead of commenting I used a condition

if false {
    // Technically, svc still be used so no yelling
    _, err = svc.SendRawEmail(input) 
    Check(err)
}

you need to put a dot between the class like

class="column.wrapper">

You could use the Laravel query builder, but this is not the best way to do it.

Check Wader's answer below for the Eloquent way - which is better as it allows you to check that there is actually a user that matches the email address, and handle the error if there isn't.

DB::table('users')
        ->where('email', $userEmail)  // find your user by their email
        ->limit(1)  // optional - to ensure only one record is updated.
        ->update(array('member_type' => $plan));  // update the record in the DB. 

If you have multiple fields to update you can simply add more values to that array at the end.

var d = new Date();
var n = d.getFullYear();

Yes, n will give you the 4 digit year, but you can always use substring or something similar to split up the year, thus giving you only two digits:

var final = n.toString().substring(2);

This will give you the last two digits of the year (2013 will become 13, etc...)

If there's a better way, hopefully someone posts it! This is the only way I can think of. Let us know if it works!

Yes it remains the same. but why not easily test it? Make an ArrayList, fill it and then retrieve the elements!

Here I have an example of Bootstrap 3 popover showing an image with the tittle above it when the mouse hovers over some text. I've put in some inline styling that you may want to take out or change.....

This also works pretty well on mobile devices because the image will popup on the first tap and the link will open on the second. html:

you are trying to open a socket to a file on the remote host which is not correct. you could make a socket connection (TCP/UDP) to a port number on a remote host. so your code should be like this:

fsockopen('www.mysite.com', 80);

if you are trying to create a file pointer resource to a remote file, you may use the fopen() function. but to do this, you need to specify the application protocol as well.

PHP provides default stream wrappers for URL file opens. based on the schema of the URL the appropriate stream wrapper will be called internally. the URL you are trying to open does not have a valid schema for this solution. make sure there is a schema like "http://" or "ftp://" in it.

so the code would be like this:

$fp = fopen('http://www.mysite.com/path/file.txt');

Besides I don't think the HTTP stream wrapper (that handles actions on file resources on URLs with http schema) supports writing of data. you can use fread() to read contents of a the URL through HTTP, but I'm not sure about writing.

EDIT: from comments and other answers I figured out you would want to send a HTTP request to the specified URL. the methods described in this answer are for when you want to receive data from the remote URL. if you want to send data, you can use http_request() to do this.

An easy solution which avoids looping over the ticklabes is to just use

fig.autofmt_xdate()

This command automatically rotates the xaxis labels and adjusts their position. The default values are a rotation angle 30° and horizontal alignment "right". But they can be changed in the function call

fig.autofmt_xdate(bottom=0.2, rotation=30, ha='right')

The additional bottom argument is equivalent to setting plt.subplots_adjust(bottom=bottom), which allows to set the bottom axes padding to a larger value to host the rotated ticklabels.

So basically here you have all the settings you need to have a nice date axis in a single command.

A good example can be found on the matplotlib page.

To add all file at a time, use git add -A

To check git whole status, use git log

In my case, a template had a typo so instead of checking for equivalency (==) it was using an assignment equals (=).

So I changed the template logic from:

if (user1.id = user2.id) ...

to

if (user1.id == user2.id) ...

and now everything is fine. So, check your views as well!

you put this css for svg circle.

svg:hover circle{
    fill: #F6831D;
    stroke-dashoffset: 0;
    stroke-dasharray: 700;
    stroke-width: 2;
}

Run php -f /common/configs/config_templates.inc.php to verify the validity of the PHP syntax in the file.

Good cocoa function:

-(BOOL) NSStringIsValidEmail:(NSString *)checkString
{
   BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
   NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
   NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
   NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
   NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
   return [emailTest evaluateWithObject:checkString];
}

Discussion on Lax vs. Strict - http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/

And because categories are just better, you could also add an interface:

@interface NSString (emailValidation) 
  - (BOOL)isValidEmail;
@end

Implement

@implementation NSString (emailValidation)
-(BOOL)isValidEmail
{
  BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
  NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
  NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
  NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
  NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
  return [emailTest evaluateWithObject:self];
}
@end

And then utilize:

if([@"[email protected]" isValidEmail]) { /* True */ }
if([@"InvalidEmail@notreallyemailbecausenosuffix" isValidEmail]) { /* False */ }

Select * from (Select orgName,id,
ROW_NUMBER() OVER(Partition By OrgName ORDER by id DESC) Rownum
From organizations )tbl Where Rownum>1

So the records with rowum> 1 will be the duplicate records in your table. ‘Partition by’ first group by the records and then serialize them by giving them serial nos. So rownum> 1 will be the duplicate records which could be deleted as such.

I was having a problem with ASP.NET MVC 5 where CheckBoxFor would not check my checkboxes on server-side validation failure even though my model clearly had the value set to true. My Razor markup/code looked like:

@Html.CheckBoxFor(model => model.MyBoolValue, new { @class = "mySpecialClass" } )

To get this to work, I had to change this to:

@{
    var checkboxAttributes = Model.MyBoolValue ?
        (object) new { @class = "mySpecialClass", @checked = "checked" } :
        (object) new { @class = "mySpecialClass" };
}
@Html.CheckBox("MyBoolValue", checkboxAttributes)

@roo: Encapsulation is not broken here because the class itself dictates who can access its private members. Encapsulation would only be broken if this could be caused from outside the class, e.g. if your operator << would proclaim “I'm a friend of class foo.”

friend replaces use of public, not use of private!

Actually, the C++ FAQ answers this already.

Use Thread.sleep(2000); //2000 for 2 seconds

Try the asyncproc module. For example:

import os
from asyncproc import Process
myProc = Process("myprogram.app")

while True:
    # check to see if process has ended
    poll = myProc.wait(os.WNOHANG)
    if poll != None:
        break
    # print any new output
    out = myProc.read()
    if out != "":
        print out

The module takes care of all the threading as suggested by S.Lott.

Not Bootstrap specific really... You can use inline styles or define a custom class to specify the desired "background-color".

On the other hand, Bootstrap does have a few built in background colors that have semantic meaning like "bg-success" (green) and "bg-danger" (red).

As you know the display property cannot be animated BUT just by having it in your CSS it overrides the visibility and opacity transitions.

The solution...just removed the display properties.

nav.main ul ul {_x000D_
  position: absolute;_x000D_
  list-style: none;_x000D_
  opacity: 0;_x000D_
  visibility: hidden;_x000D_
  padding: 10px;_x000D_
  background-color: rgba(92, 91, 87, 0.9);_x000D_
  -webkit-transition: opacity 600ms, visibility 600ms;_x000D_
  transition: opacity 600ms, visibility 600ms;_x000D_
}_x000D_
nav.main ul li:hover ul {_x000D_
  visibility: visible;_x000D_
  opacity: 1;_x000D_
}

<nav class="main">_x000D_
  <ul>_x000D_
    <li>_x000D_
      <a href="">Lorem</a>_x000D_

      </ul>_x000D_
    </li>_x000D_
  </ul>_x000D_
</nav>

The difference is, re.match() misleads anyone accustomed to Perl, grep, or sed regular expression matching, and re.search() does not. :-)

More soberly, As John D. Cook remarks, re.match() "behaves as if every pattern has ^ prepended." In other words, re.match('pattern') equals re.search('^pattern'). So it anchors a pattern's left side. But it also doesn't anchor a pattern's right side: that still requires a terminating $.

Frankly given the above, I think re.match() should be deprecated. I would be interested to know reasons it should be retained.

This was my solution:

I added required to the select tag:

                <div class="col-lg-10">
                <select class="form-control" name="HoursEntry" id="HoursEntry" required>

If you patch /Developer/Platforms/iPhoneOS.platform/Info.plist and then try to debug a application running on the device using a real development provisionen profile from Apple it will probably not work. Symptoms are weird error messages from com.apple.debugserver and that you can use any bundle identifier without getting a error when building in Xcode. The solution is to restore Info.plist.

Using awk:

awk '/cdef/{print $0 RS "line1" RS "line2" RS "line3" RS "line4";next}1' input.txt 

Explanation:

• You find the line you want to insert from using /.../
• You print the current line using print $0
• RS is built-in awk variable that is by default set to new-line.
• You add new lines separated by this variable
• 1 at the end results in printing of every other lines. Using next before it allows us to prevent the current line since you have already printed it using print $0.

$ awk '/cdef/{print $0 RS "line1" RS "line2" RS "line3" RS "line4";next}1' input.txt
abcd
accd
cdef
line1
line2
line3
line4
line
web

To make changes to the file you can do:

awk '...' input.txt > tmp && mv tmp input.txt

[HttpPost]
public string MyMethod([FromBody]JObject data)
{
    Customer customer = data["customerData"].ToObject<Customer>();
    Product product = data["productData"].ToObject<Product>();
    Employee employee = data["employeeData"].ToObject<Employee>();
    //... other class....
}

using referance

using Newtonsoft.Json.Linq;

Use Request for JQuery Ajax

var customer = {
    "Name": "jhon",
    "Id": 1,
};
var product = {
    "Name": "table",
    "CategoryId": 5,
    "Count": 100
};
var employee = {
    "Name": "Fatih",
    "Id": 4,
};

var myData = {};
myData.customerData = customer;
myData.productData = product;
myData.employeeData = employee;

$.ajax({
    type: 'POST',
    async: true,
    dataType: "json",
    url: "Your Url",
    data: myData,
    success: function (data) {
        console.log("Response Data ?");
        console.log(data);
    },
    error: function (err) {
        console.log(err);
    }
});

You should check out heroku_san, it solves this problem quite nicely.

For example, you could:

git checkout BRANCH
rake qa deploy

It also makes it easy to spin up new Heroku instances to deploy a topic branch to new servers:

git checkout BRANCH
# edit config/heroku.yml with new app instance and shortname
rake shortname heroku:create deploy # auto creates deploys and migrates

And of course you can make simpler rake tasks if you do something frequently.

Don't declare the variable in the userform. Declare it as Public in the module.

Public pass As String

In the Userform

Private Sub CommandButton1_Click()
    pass = UserForm1.TextBox1
    Unload UserForm1
End Sub

In the Module

Public pass As String

Public Sub Login()
    '
    '~~> Rest of the code
    '
    UserForm1.Show
    driver.findElementByName("PASSWORD").SendKeys pass
    '
    '~~> Rest of the code
    '
End Sub

You might want to also add an additional check just before calling the driver.find... line?

If Len(Trim(pass)) <> 0 Then

This will ensure that a blank string is not passed.

In my case, I found (after much hair-pulling) that the "pending" status was caused by the AdBlock extension. The image that I couldn't get to load had the word "ad" in the URL, so AdBlock kept it from loading.

Disabling AdBlock fixes this issue.

Renaming the file so that it doesn't contain "ad" in the URL also fixes it, and is obviously a better solution. Unless it's an advertisement, in which case you should leave it like that. :)

You are trying access a non-static class in a static way. Change Builder to static class Builder and it should work.

The example usage you give fails because there is no instance of Builder present. A static class for all practical purposes is always instantiated. If you don't make it static, you'd need to say:

Widget = new Widget.Builder(10).setparm1(1).setparm2(3).build();

Because you would need to construct a new Builder every time.

tuple_list = [("pineapple", 5), ("cherry", 7), ("kumquat", 3), ("plum", 11)]

def eachtuple(tupple, pos1, val):
    for e in tupple:
        if e == val:
            return True

for e in tuple_list:
    if eachtuple(e, 1, 7) is True:
        print tuple_list.index(e)

for e in tuple_list:
    if eachtuple(e, 0, "kumquat") is True:
        print tuple_list.index(e)

Simply u can add this to jquery.validationEngine-en.js file

    "onlyLetterNumberSp": {
                "regex": ^[A-Za-z0-9 _]*[A-Za-z0-9][A-Za-z0-9 _]*$,
                "alertText": "* No special characters allowed"
          },

and call it in text field as

<input type="text" class="form-control validate[required,custom[onlyLetterNumberSp]]"  id="title" name="title" placeholder="Title"/>

So interestingly enough this error "Transport endpoint is not connected" was caused by my having more than one Veracrypt device mounted. I closed the extra device and suddenly I had access to the drive. Hmm..

With absolute or relative positioning, you can do all sorts of overlapping. You've probably want the logo to be styled as such:

div#logo {
  position: absolute;
  left: 100px; // or whatever
}

Note: absolute position has its eccentricities. You'll probably have to experiment a little, but it shouldn't be too hard to do what you want.

Try http://www.sql-server-helper.com/tips/date-formats.aspx. Lists all formats needed. In this case select Convert(varchar(10),CONVERT(date,YourDateColumn,106),103) change 103 to 104 id you need dd.mm.yyyy

Following code works on my machine

1. you probably have something missing in your code.
2. please also check the code files's encoding.

3. make sure you have PIL package installed

   import Tkinter as tk
   from PIL import ImageTk, Image
   
   path = 'C:/xxxx/xxxx.jpg'
   
   root = tk.Tk()
   img = ImageTk.PhotoImage(Image.open(path))
   panel = tk.Label(root, image = img)
   panel.pack(side = "bottom", fill = "both", expand = "yes")
   root.mainloop()
