I had the SAME issue today and it was driving me nuts!!! What I had done was upgrade to node 8.10 and upgrade my NPM to the latest I uninstalled angular CLI
npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
I then verified my Cache from NPM if it wasn't up to date I cleaned it and ran the install again
if npm version is < 5 then use npm cache clean --force
npm install -g @angular/cli@latest
and created a new project file and create a new angular project.
That particular package does not include assemblies for dotnet core, at least not at present. You may be able to build it for core yourself with a few tweaks to the project file, but I can't say for sure without diving into the source myself.
One important fact about NVIDIA drivers that is not very well known is that its built is done by DKMS. This allows automatic rebuild in case of kernel upgrade, this happens on system startup. Because of that, it's quite easy to miss error messages, especially if you're working on cloud VM, or server without an additional IPMI/management interface. However, it's possible to trigger DKMS build just executing dkms autoinstall
right after packages installation. If this fails then you'll have a meaningful error message about missing dependency or what so ever. If dkms autoinstall
builds modules correctly you can simply load it by modprobe
- there is no need to reboot the system (which is often used as a way to trigger DKMS rebuild).
You can check an example here
If you have been given a Session Token also, then you need to manually set it after configure
:
aws configure set aws_session_token "<<your session token>>"
See example here: Input and Output binary streams using JERSEY?
Pseudo code would be something like this (there are a few other similar options in above mentioned post):
@Path("file/")
@GET
@Produces({"application/pdf"})
public StreamingOutput getFileContent() throws Exception {
public void write(OutputStream output) throws IOException, WebApplicationException {
try {
//
// 1. Get Stream to file from first server
//
while(<read stream from first server>) {
output.write(<bytes read from first server>)
}
} catch (Exception e) {
throw new WebApplicationException(e);
} finally {
// close input stream
}
}
}
you need /q at the end
MsiExec.exe /x {2F808931-D235-4FC7-90CD-F8A890C97B2F} /q
For Windows, javac
should be a command that you can run from anywhere. If it isn't (which is strange in and of itself), you need to run javac
from where it's located, but navigate to the exact location of your Java class file in order to compile it successfully.
By default, javac
will compile a file name relative to the current path, and if it can't find the file, it won't compile it.
Please note: You would only be able to use jdk1.8.0 to actually compile, since that would be the only library set that has javac
contained in it. Remember: the Java Runtime Environment runs Java classes; the Java Development Kit compiles them.
The problem you have is related to TCP streaming nature.
The fact that you sent 100 Bytes (for example) from the server doesn't mean you will read 100 Bytes in the client the first time you read. Maybe the bytes sent from the server arrive in several TCP segments to the client.
You need to implement a loop in which you read until the whole message was received.
Let me provide an example with DataInputStream
instead of BufferedinputStream
. Something very simple to give you just an example.
Let's suppose you know beforehand the server is to send 100 Bytes of data.
In client you need to write:
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
while(!end)
{
int bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length == 100)
{
end = true;
}
}
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
Now, typically the data size sent by one node (the server here) is not known beforehand. Then you need to define your own small protocol for the communication between server and client (or any two nodes) communicating with TCP.
The most common and simple is to define TLV: Type, Length, Value. So you define that every message sent form server to client comes with:
So you know you have to receive a minimum of 2 Bytes and with the second Byte you know how many following Bytes you need to read.
This is just a suggestion of a possible protocol. You could also get rid of "Type".
So it would be something like:
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
int bytesRead = 0;
messageByte[0] = in.readByte();
messageByte[1] = in.readByte();
int bytesToRead = messageByte[1];
while(!end)
{
bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length == bytesToRead )
{
end = true;
}
}
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
The following code compiles and looks better. It assumes the first two bytes providing the length arrive in binary format, in network endianship (big endian). No focus on different encoding types for the rest of the message.
import java.nio.ByteBuffer;
import java.io.DataInputStream;
import java.net.ServerSocket;
import java.net.Socket;
class Test
{
public static void main(String[] args)
{
byte[] messageByte = new byte[1000];
boolean end = false;
String dataString = "";
try
{
Socket clientSocket;
ServerSocket server;
server = new ServerSocket(30501, 100);
clientSocket = server.accept();
DataInputStream in = new DataInputStream(clientSocket.getInputStream());
int bytesRead = 0;
messageByte[0] = in.readByte();
messageByte[1] = in.readByte();
ByteBuffer byteBuffer = ByteBuffer.wrap(messageByte, 0, 2);
int bytesToRead = byteBuffer.getShort();
System.out.println("About to read " + bytesToRead + " octets");
//The following code shows in detail how to read from a TCP socket
while(!end)
{
bytesRead = in.read(messageByte);
dataString += new String(messageByte, 0, bytesRead);
if (dataString.length() == bytesToRead )
{
end = true;
}
}
//All the code in the loop can be replaced by these two lines
//in.readFully(messageByte, 0, bytesToRead);
//dataString = new String(messageByte, 0, bytesToRead);
System.out.println("MESSAGE: " + dataString);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
finally solved my problem.
I created a new project in XCode with the sources and changed the C++ Standard Library from the default libc++ to libstdc++ as in this and this.
Code for adding fragment
public Fragment getItem(int position) {
switch (position){
case 0:
return new Fragment1();
case 1:
return new Fragment2();
case 2:
return new Fragment3();
case 3:
return new Fragment4();
default:
break;
}
return null;
}
Create an xml file for each fragment say for Fragment1, use fragment_one.xml as layout file, use the below code in Fragment1 java file.
public class Fragment1 extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_one, container, false);
return view;
}
}
Later you can make necessary corrections.. It worked for me.
cmd /c "command" syntax works well. Also, if you want to include an executable that contains a space in the path, you will need two sets of quotes.
cmd /c ""path to executable""
and if your executable needs a file input with a space in the path a another set
cmd /c ""path to executable" -f "path to file""
The below query helps to get the row number in oracle,
SELECT ROWNUM AS SNO,ID,NAME,EMAIL,BRANCH FROM student WHERE NAME LIKE '%ram%';
in cmd set Visual Studio path depending upon ur version as
Visual Studio 2010 (VS10): SET VS90COMNTOOLS=%VS100COMNTOOLS%
Visual Studio 2012 (VS11): SET VS90COMNTOOLS=%VS110COMNTOOLS%
Visual Studio 2013 (VS12): SET VS90COMNTOOLS=%VS120COMNTOOLS%
In node-master( original node module downloaded from git ) run vcbuild.bat with admin privileges. vcbild.bat will generate windows related dependencies and will add folder name Release in node-master
Once it run it will take time to build the files.
Then in the directory having .gyp file use command
node-gyp rebuild --msvs_version=2012 --nodedir="Dive Name:\path to node-master\node-master"
this will build all the dependencies.
make sure that your path is pointing to .exe file in C:\Program Files\7-Zip (may in bin directory)
If you are using GNU MCU Eclipse on Windows, make sure Windows Build Tools are installed, then check the installation path and fill the "Global Build Tools Path" inside Eclipse Window/Preferences... :

Sum of total_vm
is 847170 and sum of rss
is 214726, these two values are counted in 4kB pages, which means when oom-killer was running, you had used 214726*4kB=858904kB physical memory and swap space.
Since your physical memory is 1GB and ~200MB was used for memory mapping, it's reasonable for invoking oom-killer when 858904kB was used.
rss
for process 2603 is 181503, which means 181503*4KB=726012 rss, was equal to sum of anon-rss
and file-rss
.

The cli command I've used with python for this is:
cat myfile.json | python -mjson.tool
You should be able to find more info here:
Python 2 or Python 3 API reference:
print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)
The file argument must be an object with a
write(string)
method; if it is not present orNone
,sys.stdout
will be used. Since printed arguments are converted to text strings,print()
cannot be used with binary mode file objects. For these, usefile.write(...)
instead.
Since file object normally contains write()
method, all you need to do is to pass a file object into its argument.
with open('file.txt', 'w') as f:
print('hello world', file=f)
with open('file.txt', 'a') as f:
print('hello world', file=f)
Try the Content-Disposition
header
Content-Disposition: attachment; filename=<file name.ext>
Here's another solution, using the ast
module:
python -c "import ast; ast.parse(open('programfile').read())"
To do it cleanly from within a Python script:
import ast, traceback
filename = 'programfile'
with open(filename) as f:
source = f.read()
valid = True
try:
ast.parse(source)
except SyntaxError:
valid = False
traceback.print_exc() # Remove to silence any errros
print(valid)
A good combination of String extensions:
public static byte[] GetBytes(this string str)
{
byte[] bytes = new byte[str.Length * sizeof(char)];
System.Buffer.BlockCopy(str.ToCharArray(), 0, bytes, 0, bytes.Length);
return bytes;
}
public static Stream ToStream(this string str)
{
Stream StringStream = new MemoryStream();
StringStream.Read(str.GetBytes(), 0, str.Length);
return StringStream;
}
byte[] bytes = File.ReadAllBytes(filename)
or ...
var bytes = File.ReadAllBytes(filename)
As of 2018 there is a much shorter and elegant solution. Just use. Array.prototype.sort().
Example:
var items = [
{ name: 'Edward', value: 21 },
{ name: 'Sharpe', value: 37 },
{ name: 'And', value: 45 },
{ name: 'The', value: -12 },
{ name: 'Magnetic', value: 13 },
{ name: 'Zeros', value: 37 }
];
// sort by value
items.sort(function (a, b) {
return a.value - b.value;
});
I would recommend using CLASS.__bases__
something like this
class A:
def __init__(self):
print "I am Class %s"%self.__class__.__name__
for parentClass in self.__class__.__bases__:
print " I am inherited from:",parentClass.__name__
#parentClass.foo(self) <- call parents function with self as first param
class B(A):pass
class C(B):pass
a,b,c = A(),B(),C()
In C#:
public bool Is64bit() {
return Marshal.SizeOf(typeof(IntPtr)) == 8;
}
In VB.NET:
Public Function Is64bit() As Boolean
If Marshal.SizeOf(GetType(IntPtr)) = 8 Then Return True
Return False
End Function
You need "src/Hankees.txt"
Your file is in the source folder which is not counted as the working directory.\
Or you can move the file up to the root directory of your project and just use "Hankees.txt"
The function below will return the x86 Program Files
directory in all of these three Windows configurations:
static string ProgramFilesx86()
{
if( 8 == IntPtr.Size
|| (!String.IsNullOrEmpty(Environment.GetEnvironmentVariable("PROCESSOR_ARCHITEW6432"))))
{
return Environment.GetEnvironmentVariable("ProgramFiles(x86)");
}
return Environment.GetEnvironmentVariable("ProgramFiles");
}
I was having this same issue and after much wrangling I decided to try and isolate the problem and simply load the script manager in an empty page which still resulted in this same error. Having isolated the problem I discovered through a comparison of my site's web.config with a brand new (working) test site that changing <compilation debug="true">
to <compilation debug="false">
in the system.web section of my web.config fixes the problem.
I also had to remove the <xhtmlConformance mode="Legacy"/>
entry from system.web to make the update panel work properly. Click here for a description of this issue.
This one works for me:
sudo chown -R $(whoami) ~/.npm
I did not use the -g
because I am the only user. I used a MacBook Air.
TL;DR;
Unicode - (nchar, nvarchar, and ntext)
Non-unicode - (char, varchar, and text).
Collations in SQL Server provide sorting rules, case, and accent sensitivity properties for your data. Collations that are used with character data types such as char and varchar dictate the code page and corresponding characters that can be represented for that data type.
Assuming you are using default SQL collation SQL_Latin1_General_CP1_CI_AS
then following script should print out all the symbols that you can fit in VARCHAR
since it uses one byte to store one character (256 total) if you don't see it on the list printed - you need NVARCHAR
.
declare @i int = 0;
while (@i < 256)
begin
print cast(@i as varchar(3)) + ' '+ char(@i) collate SQL_Latin1_General_CP1_CI_AS
print cast(@i as varchar(3)) + ' '+ char(@i) collate Japanese_90_CI_AS
set @i = @i+1;
end
If you change collation to lets say japanese you will notice that all the weird European letters turned into normal and some symbols into ?
marks.
Unicode is a standard for mapping code points to characters. Because it is designed to cover all the characters of all the languages of the world, there is no need for different code pages to handle different sets of characters. If you store character data that reflects multiple languages, always use Unicode data types (nchar, nvarchar, and ntext) instead of the non-Unicode data types (char, varchar, and text).
Otherwise your sorting will go weird.
To define the file to import it's possible to use all folders common definitions. You just have to be aware that it's relative to file you are defining it. More about import option with examples you can check here.
I have been searching for this same answer all morning and have pretty much found out that it's probably impossible to verify if every email address you ever need to check actually exists at the time you need to verify it. So as a work around, I kind of created a simple PHP
script to verify that the email address is formatted correct and it also verifies that the domain name used is correct as well.

If you want to customize the message that being shown on empty table use this:
$('#example').dataTable( {
"oLanguage": {
"sEmptyTable": "My Custom Message On Empty Table"
}
} );
Since Datatable 1.10 you can do the following:
$('#example').DataTable( {
"language": {
"emptyTable": "My Custom Message On Empty Table"
}
} );
For the complete availble datatables custom messages for the table take a look at the following link reference/option/language
The format YYYY-MM-DD is part of ISO8601 a standard for the exchange of date (and time) information.
It's very brave of Oracle to adopt an ISO standard like this, but at the same time, strange they didn't go all the way.
In general people resist anything different, but there are many good International reasons for it.
I know I'm saying revolutionary things, but we should all embrace ISO standards, even it we do it a bit at a time.
As the instructions state on the iTuneconnect Developer Guidelines you need to ensure that you are the "team agent"
to delete apps. This is stated in the quote below from the developer guidelines.
If the Delete App button isn’t displayed, check that you’re the team agent and that the app is in one of the statuses that allow the app to be deleted.
I have just checked on my account by logging in as the main account holder and the delete button is there for an app that I have previously removed from sale but when I have looked in as another user they don't have this permission, only the main account holder seems to have it.

if ( query ) { ... }
If your variable is declared but can be undefined
or null

If you don't use conda, just use :
pip install openpyxl
If you use conda, I'd recommend :
conda install -c anaconda openpyxl
instead of simply conda install openpyxl
Because there are issues right now with conda updating (see GitHub Issue #8842) ; this is being fixed and it should work again after the next release (conda 4.7.6)

The answers here are not actually completely correct. Close, but there's an edge case.
The difference is that $('body') actually selects the element by the tag name, whereas document.body references the direct object on the document.
That means if you (or a rogue script) overwrites the document.body element (shame!) $('body') will still work, but $(document.body) will not. So by definition they're not equivalent.
I'd venture to guess there are other edge cases (such as globally id'ed elements in IE) that would also trigger what amounts to an overwritten body element on the document object, and the same situation would apply.
Looking at the Eclipse plugin docs I found some useful tasks that rebuilt my classpath and updated the required dependencies.
gradle cleanEclipse
to clean the Eclipse configuration completely. If this doesn;t work you may try more specific tasks:
gradle cleanEclipseProject
to remove the .project filegradle cleanEclipseClasspath
to empty the project's classpathgradle eclipse
to rebuild the Eclipse configurationIf you want to add a dictionary within a dictionary you can do it this way.
Example: Add a new entry to your dictionary & sub dictionary
dictionary = {}
dictionary["new key"] = "some new entry" # add new dictionary entry
dictionary["dictionary_within_a_dictionary"] = {} # this is required by python
dictionary["dictionary_within_a_dictionary"]["sub_dict"] = {"other" : "dictionary"}
print (dictionary)
Output:
{'new key': 'some new entry', 'dictionary_within_a_dictionary': {'sub_dict': {'other': 'dictionarly'}}}
NOTE: Python requires that you first add a sub
dictionary["dictionary_within_a_dictionary"] = {}
before adding entries.
sort
has been replaced in v0.20 by DataFrame.sort_values
and DataFrame.sort_index
. Aside from this, we also have argsort
.
Here are some common use cases in sorting, and how to solve them using the sorting functions in the current API. First, the setup.
# Setup
np.random.seed(0)
df = pd.DataFrame({'A': list('accab'), 'B': np.random.choice(10, 5)})
df
A B
0 a 7
1 c 9
2 c 3
3 a 5
4 b 2
For example, to sort df
by column "A", use sort_values
with a single column name:
df.sort_values(by='A')
A B
0 a 7
3 a 5
4 b 2
1 c 9
2 c 3
If you need a fresh RangeIndex, use DataFrame.reset_index
.
For example, to sort by both col "A" and "B" in df
, you can pass a list to sort_values
:
df.sort_values(by=['A', 'B'])
A B
3 a 5
0 a 7
4 b 2
2 c 3
1 c 9
df2 = df.sample(frac=1)
df2
A B
1 c 9
0 a 7
2 c 3
3 a 5
4 b 2
You can do this using sort_index
:
df2.sort_index()
A B
0 a 7
1 c 9
2 c 3
3 a 5
4 b 2
df.equals(df2)
# False
df.equals(df2.sort_index())
# True
Here are some comparable methods with their performance:
%timeit df2.sort_index()
%timeit df2.iloc[df2.index.argsort()]
%timeit df2.reindex(np.sort(df2.index))
605 µs ± 13.6 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
610 µs ± 24.2 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
581 µs ± 7.63 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
For example,
idx = df2.index.argsort()
idx
# array([0, 7, 2, 3, 9, 4, 5, 6, 8, 1])
This "sorting" problem is actually a simple indexing problem. Just passing integer labels to iloc
will do.
df.iloc[idx]
A B
1 c 9
0 a 7
2 c 3
3 a 5
4 b 2
Some of the answers in this Q&A are wrong. The accepted answer is also not very "practical", so I want to post an answer that explains things in simpler terms. My answer will cover 99% of the errors I see posted over and over again. For the actual reasons behind the error take a look at the accepted answer.
HTTP uses a cycle that requires one response per request. When the client sends a request (e.g. POST or GET) the server should only send one response back to it.
This error message:
Error: Can't set headers after they are sent.
usually happens when you send several responses for one request. Make sure the following functions are called only once per request:
res.json()
res.send()
res.redirect()
res.render()
(and a few more that are rarely used, check the accepted answer)
The route callback will not return when these res functions are called. It will continue running until it hits the end of the function or a return statement. If you want to return when sending a response you can do it like so: return res.send()
.
Take for instance this code:
app.post('/api/route1', function(req, res) {
console.log('this ran');
res.status(200).json({ message: 'ok' });
console.log('this ran too');
res.status(200).json({ message: 'ok' });
}
When a POST request is sent to /api/route1 it will run every line in the callback. A Can't set headers after they are sent error message will be thrown because res.json()
is called twice, meaning two responses are sent.
Only one response can be sent per request!
The error in the code sample above was obvious. A more typical problem is when you have several branches:
app.get('/api/company/:companyId', function(req, res) {
const { companyId } = req.params;
Company.findById(companyId).exec((err, company) => {
if (err) {
res.status(500).json(err);
} else if (!company) {
res.status(404).json(); // This runs.
}
res.status(200).json(company); // This runs as well.
});
}
This route with attached callback finds a company in a database. When doing a query for a company that doesn't exist we will get inside the else if
branch and send a 404 response. After that, we will continue on to the next statement which also sends a response. Now we have sent two responses and the error message will occur. We can fix this code by making sure we only send one response:
.exec((err, company) => {
if (err) {
res.status(500).json(err);
} else if (!company) {
res.status(404).json(); // Only this runs.
} else {
res.status(200).json(company);
}
});
or by returning when the response is sent:
.exec((err, company) => {
if (err) {
return res.status(500).json(err);
} else if (!company) {
return res.status(404).json(); // Only this runs.
}
return res.status(200).json(company);
});
A big sinner is asynchronous functions. Take the function from this question, for example:
article.save(function(err, doc1) {
if (err) {
res.send(err);
} else {
User.findOneAndUpdate({ _id: req.user._id }, { $push: { article: doc._id } })
.exec(function(err, doc2) {
if (err) res.send(err);
else res.json(doc2); // Will be called second.
})
res.json(doc1); // Will be called first.
}
});
Here we have an asynchronous function (findOneAndUpdate()
) in the code sample. If there are no errors (err
) findOneAndUpdate()
will be called. Because this function is asynchronous the res.json(doc1)
will be called immediately. Assume there are no errors in findOneAndUpdate()
. The res.json(doc2)
in the else
will then be called. Two responses have now been sent and the Can't set headers error message occurs.
The fix, in this case, would be to remove the res.json(doc1)
. To send both docs back to the client the res.json()
in the else could be written as res.json({ article: doc1, user: doc2 })
.
Use Arrays.asList()
to wrap the array in a List<String>

You need to define a new type and define your function to return that type.
CREATE TYPE my_type AS (f1 varchar(10), f2 varchar(10) /* , ... */ );
CREATE OR REPLACE FUNCTION get_object_fields(name text)
RETURNS my_type
AS
$$
DECLARE
result_record my_type;
BEGIN
SELECT f1, f2, f3
INTO result_record.f1, result_record.f2, result_record.f3
FROM table1
WHERE pk_col = 42;
SELECT f3
INTO result_record.f3
FROM table2
WHERE pk_col = 24;
RETURN result_record;
END
$$ LANGUAGE plpgsql;
If you want to return more than one record you need to define the function as returns setof my_type
Update
Another option is to use RETURNS TABLE()
instead of creating a TYPE
which was introduced in Postgres 8.4
CREATE OR REPLACE FUNCTION get_object_fields(name text)
RETURNS TABLE (f1 varchar(10), f2 varchar(10) /* , ... */ )
...
It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.
In Web API, it's very simple to remember how parameter binding is happening.
POST
simple types, Web API tries to bind it from the URL if you POST
complex type, Web API tries to bind it from the body of
the request (this uses a media-type
formatter).
If you want to bind a complex type from the URL, you'll use [FromUri]
in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.
public IHttpActionResult Put([FromUri] ViewModel data) { ... }
If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.
public IHttpActionResult Put([FromBody] string name) { ... }
as a side note, say you are making a PUT
request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data
parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.
var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});
and your web api action will look something like below.
public IHttpActionResult Put([FromBody] string name){ ... }
This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api
If you've already pushed things to a remote server (and you have other developers working off the same remote branch) the important thing to bear in mind is that you don't want to rewrite history
Don't use git reset --hard
You need to revert changes, otherwise any checkout that has the removed commits in its history will add them back to the remote repository the next time they push; and any other checkout will pull them in on the next pull thereafter.
If you have not pushed changes to a remote, you can use
git reset --hard <hash>
If you have pushed changes, but are sure nobody has pulled them you can use
git reset --hard
git push -f
If you have pushed changes, and someone has pulled them into their checkout you can still do it but the other team-member/checkout would need to collaborate:
(you) git reset --hard <hash>
(you) git push -f
(them) git fetch
(them) git reset --hard origin/branch
But generally speaking that's turning into a mess. So, reverting:
The commits to remove are the lastest
This is possibly the most common case, you've done something - you've pushed them out and then realized they shouldn't exist.
First you need to identify the commit to which you want to go back to, you can do that with:
git log
just look for the commit before your changes, and note the commit hash. you can limit the log to the most resent commits using the -n
flag: git log -n 5
Then reset your branch to the state you want your other developers to see:
git revert <hash of first borked commit>..HEAD
The final step is to create your own local branch reapplying your reverted changes:
git branch my-new-branch
git checkout my-new-branch
git revert <hash of each revert commit> .
Continue working in my-new-branch
until you're done, then merge it in to your main development branch.
The commits to remove are intermingled with other commits
If the commits you want to revert are not all together, it's probably easiest to revert them individually. Again using git log
find the commits you want to remove and then:
git revert <hash>
git revert <another hash>
..
Then, again, create your branch for continuing your work:
git branch my-new-branch
git checkout my-new-branch
git revert <hash of each revert commit> .
Then again, hack away and merge in when you're done.
You should end up with a commit history which looks like this on my-new-branch
2012-05-28 10:11 AD7six o [my-new-branch] Revert "Revert "another mistake""
2012-05-28 10:11 AD7six o Revert "Revert "committing a mistake""
2012-05-28 10:09 AD7six o [master] Revert "committing a mistake"
2012-05-28 10:09 AD7six o Revert "another mistake"
2012-05-28 10:08 AD7six o another mistake
2012-05-28 10:08 AD7six o committing a mistake
2012-05-28 10:05 Bob I XYZ nearly works
Better way®
Especially that now that you're aware of the dangers of several developers working in the same branch, consider using feature branches always for your work. All that means is working in a branch until something is finished, and only then merge it to your main branch. Also consider using tools such as git-flow to automate branch creation in a consistent way.
You're currently trying to remove the exact string []
- two square brackets with nothing between them. Instead, you want to remove all [
and separately remove all ]
.
Personally I would avoid using replaceAll
here as it introduces more confusion due to the regex part - I'd use:
String replaced = original.replace("[", "").replace("]", "");
Only use the methods which take regular expressions if you really want to do full pattern matching. When you just want to replace all occurrences of a fixed string, replace
is simpler to read and understand.
(There are alternative approaches which use the regular expression form and really match patterns, but I think the above code is significantly simpler.)
I found another issue, for some reason if the extensions are cached in the local AppData folder, the XNA extensions never get loaded.
You need to remove the files extensionSdks.en-US.cache
and extensions.en-US.cache
from the %LocalAppData%\Microsoft\VisualStudio\11.0\Extensions
folder. These files are rebuilt the next time you launch
If you need access to the Visual Studio startup log to debug what's happening, run devenv.exe /log
command from the C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE
directory (assuming you are on a 64 bit machine). The log file generated is located here:
%AppData%\Microsoft\VisualStudio\11.0\ActivityLog.xml
Add this in your input element
<input
action="action"
onclick="window.history.go(-1); return false;"
type="submit"
value="Cancel"
/>
For me the easiest way is definitely to use a BackgroundWorker
, which is specifically designed for this kind of task. The ProgressChanged
event is perfectly fitted to update a progress bar, without worrying about cross-thread calls
Basically, Python lists are very flexible and can hold completely heterogeneous, arbitrary data, and they can be appended to very efficiently, in amortized constant time. If you need to shrink and grow your list time-efficiently and without hassle, they are the way to go. But they use a lot more space than C arrays, in part because each item in the list requires the construction of an individual Python object, even for data that could be represented with simple C types (e.g. float
or uint64_t
).
The array.array
type, on the other hand, is just a thin wrapper on C arrays. It can hold only homogeneous data (that is to say, all of the same type) and so it uses only sizeof(one object) * length
bytes of memory. Mostly, you should use it when you need to expose a C array to an extension or a system call (for example, ioctl
or fctnl
).
array.array
is also a reasonable way to represent a mutable string in Python 2.x (array('B', bytes)
). However, Python 2.6+ and 3.x offer a mutable byte string as bytearray
.
However, if you want to do math on a homogeneous array of numeric data, then you're much better off using NumPy, which can automatically vectorize operations on complex multi-dimensional arrays.
To make a long story short: array.array
is useful when you need a homogeneous C array of data for reasons other than doing math.
Foo
variable will never ever take up memory.using
statement simply calls dispose on an IDisposable
object when it exits, so this is equivalent to your second bullet point. Both will indicate that you are done with the object and tell the GC that you are ready to let go of it. Overwriting the only reference to the object will have a similar effect.carlpett's find
-based answer (find . -maxdepth 1 -type f
) works in principle, but is not quite the same as using ls
: you get a potentially unsorted list of filenames all prefixed with ./
, and you lose the ability to apply ls
's many options;
also find
invariably finds hidden items too, whereas ls
' behavior depends on the presence or absence of the -a
or -A
options.
An improvement, suggested by Alex Hall in a comment on the question is to combine shell globbing with find
:
find * -maxdepth 0 -type f # find -L * ... includes symlinks to files
ls
's many other sorting / output-format options.Hans Roggeman's ls
+ grep
answer is pragmatic, but locks you into using long (-l
) output format.
To address these limitations I wrote the fls
(filtering ls) utility,
ls
while also providing type-filtering capability,f
for files, d
for directories, and l
for symlinks before a list of ls
arguments (run fls --help
or fls --man
to learn more).Examples:
fls f # list all files in current dir.
fls d -tA ~ # list dirs. in home dir., including hidden ones, most recent first
fls f^l /usr/local/bin/c* # List matches that are files, but not (^) symlinks (l)
Supported platforms
Note: Even if you don't use Node.js, its package manager, npm
, works across platforms and is easy to install; try
curl -L https://git.io/n-install | bash
With Node.js installed, install as follows:
[sudo] npm install fls -g
Note:
Whether you need sudo
depends on how you installed Node.js / io.js and whether you've changed permissions later; if you get an EACCES
error, try again with sudo
.
The -g
ensures global installation and is needed to put fls
in your system's $PATH
.
bash
script as fls
.chmod +x fls
.$PATH
, such as /usr/local/bin
(macOS) or /usr/bin
(Linux).The cursor is the Interface that represents a 2-dimensional
table of any database.
When you try to retrieve some data using SELECT
statement, then the database will 1st create a CURSOR object and return its reference to you.
The pointer of this returned reference is pointing to the 0th location which is otherwise called as before the first location of the Cursor, so when you want to retrieve data from the cursor, you have to 1st move to the 1st record so we have to use moveToFirst
When you invoke moveToFirst()
method on the Cursor, it takes the cursor pointer to the 1st location. Now you can access the data present in the 1st record
The best way to look :
Cursor cursor
for (cursor.moveToFirst();
!cursor.isAfterLast();
cursor.moveToNext()) {
.........
}
copy connection string to app.config
or web.config
file in the project which has set to "Set as StartUp

Rob's answer would be the most vendor-agnostic, but if you're using MySQL the safer and correct choise would be the built-in LAST_INSERT_ID()
function.
Gradle 4.9+
gradle run --args='arg1 arg2'
This assumes your build.gradle
is configured with the Application plugin. Your build.gradle
should look similar to this:
plugins {
// Implicitly applies Java plugin
id: 'application'
}
application {
// URI of your main class/application's entry point (required)
mainClassName = 'org.gradle.sample.Main'
}
Pre-Gradle 4.9
Include the following in your build.gradle
:
run {
if (project.hasProperty("appArgs")) {
args Eval.me(appArgs)
}
}
Then to run: gradle run -PappArgs="['arg1', 'args2']"
If you are doing a loading screen, just set the parameter to not keep it in activity stack. In your manifest.xml, where you define your activity do:
<activity android:name=".LoadingScreen" android:noHistory="true" ... />
And in your code there is no need to call .finish() anymore. Just do startActivity(i);
There is also no need to keep a instance of your current activity in a separate field. You can always access it like LoadingScreen.this.doSomething()
instead of private LoadingScreen loadingScreen;
For my purposes I ended up using an alternative https://www.openstreetmap.org/ .
In MySQL TRUE
and FALSE
are synonyms for TINYINT(1)
.
So therefore its basically the same thing, but MySQL is converting to 0/1 - so just use a TINYINT
if that's easier for you
P.S.
The performance is likely to be so minuscule (if at all), that if you need to ask on StackOverflow, then it won't affect your database :)
In some cases it is tied to how the field is used. In some DB engines the field differences determine how (and if) you search for text in the field. CharFields are typically used for things that are searchable, like if you want to search for "one" in the string "one plus two". Since the strings are shorter they are less time consuming for the engine to search through. TextFields are typically not meant to be searched through (like maybe the body of a blog) but are meant to hold large chunks of text. Now most of this depends on the DB Engine and like in Postgres it does not matter.
Even if it does not matter, if you use ModelForms you get a different type of editing field in the form. The ModelForm will generate an HTML form the size of one line of text for a CharField and multiline for a TextField.
This code works too:
$("input[reference=12345].myclass").css('border', '#000 solid 1px');
setAlpha(int)

You can use Resharper to change your all namespace definitions in your solution. This is the best way I tried before.

That depends on a lot of factors. Processes are more heavy-weight than threads, and have a higher startup and shutdown cost. Interprocess communication (IPC) is also harder and slower than interthread communication.
Conversely, processes are safer and more secure than threads, because each process runs in its own virtual address space. If one process crashes or has a buffer overrun, it does not affect any other process at all, whereas if a thread crashes, it takes down all of the other threads in the process, and if a thread has a buffer overrun, it opens up a security hole in all of the threads.
So, if your application's modules can run mostly independently with little communication, you should probably use processes if you can afford the startup and shutdown costs. The performance hit of IPC will be minimal, and you'll be slightly safer against bugs and security holes. If you need every bit of performance you can get or have a lot of shared data (such as complex data structures), go with threads.
Use the BigInteger
class that is a part of the Java library.
http://java.sun.com/j2se/1.5.0/docs/api/java/math/BigInteger.html
How to do this was added to the official Django docs in Django1.4
https://docs.djangoproject.com/en/1.10/topics/db/queries/#copying-model-instances
The official answer is similar to miah's answer, but the docs point out some difficulties with inheritance and related objects, so you should probably make sure you read the docs.
I had the same need and found this answer ..
This creates a record in the company table (comp), it the grabs the auto ID created on the company table and drops that into a Staff table (staff) so the 2 tables can be linked, MANY staff to ONE company. It works on my SQL 2008 DB, should work on SQL 2005 and above.
===========================
CREATE PROCEDURE [dbo].[InsertNewCompanyAndStaffDetails]
@comp_name varchar(55) = 'Big Company',
@comp_regno nchar(8) = '12345678',
@comp_email nvarchar(50) = '[email protected]',
@recID INT OUTPUT
-- The '@recID' is used to hold the Company auto generated ID number that we are about to grab
AS
Begin
SET NOCOUNT ON
DECLARE @tableVar TABLE (tempID INT)
-- The line above is used to create a tempory table to hold the auto generated ID number for later use. It has only one field 'tempID' and its type INT is the same as the '@recID'.
INSERT INTO comp(comp_name, comp_regno, comp_email)
OUTPUT inserted.comp_id INTO @tableVar
-- The 'OUTPUT inserted.' line above is used to grab data out of any field in the record it is creating right now. This data we want is the ID autonumber. So make sure it says the correct field name for your table, mine is 'comp_id'. This is then dropped into the tempory table we created earlier.
VALUES (@comp_name, @comp_regno, @comp_email)
SET @recID = (SELECT tempID FROM @tableVar)
-- The line above is used to search the tempory table we created earlier where the ID we need is saved. Since there is only one record in this tempory table, and only one field, it will only select the ID number you need and drop it into '@recID'. '@recID' now has the ID number you want and you can use it how you want like i have used it below.
INSERT INTO staff(Staff_comp_id)
VALUES (@recID)
End
-- So there you go. You can actually grab what ever you want in the 'OUTPUT inserted.WhatEverFieldNameYouWant' line and create what fields you want in your tempory table and access it to use how ever you want.
I was looking for something like this for ages, with this detailed break down, I hope this helps.
Another option could be:
$("#ulId").scroll(function () { console.log("Event Fired"); })
Reference: Here
I would suggest (jQuery needed) :
/*
* windowSize
* call this function to get windowSize any time
*/
function windowSize() {
windowHeight = window.innerHeight ? window.innerHeight : $(window).height();
windowWidth = window.innerWidth ? window.innerWidth : $(window).width();
}
//Init Function of init it wherever you like...
windowSize();
// For example, get window size on window resize
$(window).resize(function() {
windowSize();
console.log('width is :', windowWidth, 'Height is :', windowHeight);
if (windowWidth < 768) {
console.log('width is under 768px !');
}
});
Added in CodePen : http://codepen.io/moabi/pen/QNRqpY?editors=0011
Then you can get easily window's width with the var : windowWidth and Height with : windowHeight
otherwise, get a js library : http://wicky.nillia.ms/enquire.js/
In Doctrine 2.x you can't pass multiple order by using doctrine 'orderBy' or 'addOrderBy' as above examples. Because, it automatically adds the 'ASC' at the end of the last column name when you left the second parameter blank, such as in the 'orderBy' function.
For an example ->orderBy('a.fist_name ASC, a.last_name ASC')
will output SQL something like this 'ORDER BY first_name ASC, last_name ASC ASC'. So this is SQL syntax error. Simply because default of the orderBy or addOrderBy is 'ASC'.
To add multiple order by's you need to use 'add' function. And it will be like this.
->add('orderBy','first_name ASC, last_name ASC')
. This will give you the correctly formatted SQL.

Other instructors and teaching assistants occasionally tell me that constructors are specialized methods. I always argue that in Java constructors are NOT specialized methods.
If constructors were methods at all, I would expect them to have the same abilities as methods. That they would at least be similar in more ways than they are different.
Constructors must be invoked with the new
operator while methods may not be invoked with the new
operator. Related: Constructors may not be called by name while methods must be called by name.
Constructors may not have a return type while methods must have a return type.
If a method has the same name as the class, it must have a return type. Otherwise, it is a constructor. The fact that you can have two MyClass() signatures in the same class definition which are treated differently should convince all that constructors and methods are different entities:
public class MyClass {
public MyClass() { } // constructor
public String MyClass() { return "MyClass() method"; } // method
}
Constructors may initialize instance constants while methods may not.
Public and protected constructors are not inherited while public and protected methods are inherited.
Constructors may call the constructors of the super class or same class while methods may not call either super() or this().
They both have parameter lists.
They both have blocks of code that will be executed when that block is either called directly (methods) or invoked via new
(constructors).
Constructors may be: private, protected, public.
Methods may be: private, protected, public, abstract, static, final, synchronized, native, strictfp.
Data fields may be: private, protected, public, static, final, transient, volatile.
In Java, the form and function of constructors is significantly different than for methods. Thus, calling them specialized methods actually makes it harder for new programmers to learn the differences. They are much more different than similar and learning them as different entities is critical in Java.
I do recognize that Java is different than other languages in this regard, namely C++, where the concept of specialized methods originates and is supported by the language rules. But, in Java, constructors are not methods at all, much less specialized methods.
Even javadoc recognizes the differences between constructors and methods outweigh the similarities; and provides a separate section for constructors.
Neither.
Django is a framework, not a language. Python is the language in which Django is written.
Django is a collection of Python libs allowing you to quickly and efficiently create a quality Web application, and is suitable for both frontend and backend.
However, Django is pretty famous for its "Django admin", an auto generated backend that allows you to manage your website in a blink for a lot of simple use cases without having to code much.
More precisely, for the front end, Django helps you with data selection, formatting, and display. It features URL management, a templating language, authentication mechanisms, cache hooks, and various navigation tools such as paginators.
For the backend, Django comes with an ORM that lets you manipulate your data source with ease, forms (an HTML independent implementation) to process user input and validate data and signals, and an implementation of the observer pattern. Plus a tons of use-case specific nifty little tools.
For the rest of the backend work Django doesn't help with, you just use regular Python. Business logic is a pretty broad term.
You probably want to know as well that Django comes with the concept of apps, a self contained pluggable Django library that solves a problem. The Django community is huge, and so there are numerous apps that do specific business logic that vanilla Django doesn't.
Assuming two decimal places on your percentages, the data type you use depends on how you plan to store your percentages. If you are going to store their fractional equivalent (e.g. 100.00% stored as 1.0000), I would store the data in a decimal(5,4)
data type with a CHECK
constraint that ensures that the values never exceed 1.0000 (assuming that is the cap) and never go below 0 (assuming that is the floor). If you are going to store their face value (e.g. 100.00% is stored as 100.00), then you should use decimal(5,2)
with an appropriate CHECK
constraint. Combined with a good column name, it makes it clear to other developers what the data is and how the data is stored in the column.
The individual alphabets or symbols residing in a single cell can be inserted into different cells in different columns by the following code:
For i = 1 To Len(Cells(1, 1))
Cells(2, i) = Mid(Cells(1, 1), i, 1)
Next
If you do not want the symbols like colon to be inserted put an if condition in the loop.
I have written an application using WPF, Prism and MVVM to simulate hiring a cab, you can read about it on my blog, download the source here and play with it.

In JavaScript strings can be either string primitive type or string objects. The following code shows the distinction:
var a: string = 'test'; // string literal
var b: String = new String('another test'); // string wrapper object
console.log(typeof a); // string
console.log(typeof b); // object
Your error:
Type 'String' is not assignable to type 'string'. 'string' is a primitive, but 'String' is a wrapper object. Prefer using 'string' when possible.
Is thrown by the TS compiler because you tried to assign the type string
to a string object type (created via new
keyword). The compiler is telling you that you should use the type string
only for strings primitive types and you can't use this type to describe string object types.

After you've retrieved the reflect.Value
of the field by using Field(i)
you can get a
interface value from it by calling Interface()
. Said interface value then represents the
value of the field.
There is no function to convert the value of the field to a concrete type as there are,
as you may know, no generics in go. Thus, there is no function with the signature GetValue() T
with T
being the type of that field (which changes of course, depending on the field).
The closest you can achieve in go is GetValue() interface{}
and this is exactly what reflect.Value.Interface()
offers.
The following code illustrates how to get the values of each exported field in a struct using reflection (play):
import (
"fmt"
"reflect"
)
func main() {
x := struct{Foo string; Bar int }{"foo", 2}
v := reflect.ValueOf(x)
values := make([]interface{}, v.NumField())
for i := 0; i < v.NumField(); i++ {
values[i] = v.Field(i).Interface()
}
fmt.Println(values)
}
You are most likely pushing a string 'NULL'
to the table, rather then an actual NULL
, but other things may be going on as well, an illustration:
mysql> CREATE TABLE date_test (pdd DATE NOT NULL);
Query OK, 0 rows affected (0.11 sec)
mysql> INSERT INTO date_test VALUES (NULL);
ERROR 1048 (23000): Column 'pdd' cannot be null
mysql> INSERT INTO date_test VALUES ('NULL');
Query OK, 1 row affected, 1 warning (0.05 sec)
mysql> show warnings;
+---------+------+------------------------------------------+
| Level | Code | Message |
+---------+------+------------------------------------------+
| Warning | 1265 | Data truncated for column 'pdd' at row 1 |
+---------+------+------------------------------------------+
1 row in set (0.00 sec)
mysql> SELECT * FROM date_test;
+------------+
| pdd |
+------------+
| 0000-00-00 |
+------------+
1 row in set (0.00 sec)
mysql> ALTER TABLE date_test MODIFY COLUMN pdd DATE NULL;
Query OK, 1 row affected (0.15 sec)
Records: 1 Duplicates: 0 Warnings: 0
mysql> INSERT INTO date_test VALUES (NULL);
Query OK, 1 row affected (0.06 sec)
mysql> SELECT * FROM date_test;
+------------+
| pdd |
+------------+
| 0000-00-00 |
| NULL |
+------------+
2 rows in set (0.00 sec)
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
I am not sure if there is a mysql version of this but adding this line of code allows throwing mysqli_sql_exception.
I know, passed a lot of time and the question is already checked answered but I got a different answer and it may be helpful.
string varString = "15";
int i = int.Parse(varString);
or
int varI;
string varString = "15";
int.TryParse(varString, out varI);
int.TryParse
is safer since if you put something else in varString
(for example "fsfdsfs") you would get an exception. By using int.TryParse
when string can't be converted into int it will return 0
.
The simplest solution if you are just storing two strings is NSUserDefaults
, in Swift 3 this class has been renamed to just UserDefaults
.
It's best to store your keys somewhere globally so that you can reuse them elsewhere in your code.
struct defaultsKeys {
static let keyOne = "firstStringKey"
static let keyTwo = "secondStringKey"
}
// Setting
let defaults = UserDefaults.standard
defaults.set("Some String Value", forKey: defaultsKeys.keyOne)
defaults.set("Another String Value", forKey: defaultsKeys.keyTwo)
// Getting
let defaults = UserDefaults.standard
if let stringOne = defaults.string(forKey: defaultsKeys.keyOne) {
print(stringOne) // Some String Value
}
if let stringTwo = defaults.string(forKey: defaultsKeys.keyTwo) {
print(stringTwo) // Another String Value
}
// Setting
let defaults = NSUserDefaults.standardUserDefaults()
defaults.setObject("Some String Value", forKey: defaultsKeys.keyOne)
defaults.setObject("Another String Value", forKey: defaultsKeys.keyTwo)
// Getting
let defaults = NSUserDefaults.standardUserDefaults()
if let stringOne = defaults.stringForKey(defaultsKeys.keyOne) {
print(stringOne) // Some String Value
}
if let stringTwo = defaults.stringForKey(defaultsKeys.keyTwo) {
print(stringTwo) // Another String Value
}
For anything more serious than minor config, flags or base strings you should use some sort of persistent store - A popular option at the moment is Realm but you can also use SQLite or Apples very own CoreData.
C# has a few more features than Java. Take delegates for example: Many very simple C# applications use delegates, while the Java folks figures that the observer pattern was sufficient. So, in order for a tool to convert a C# application which uses delegates it would have to translate the structure from using delegates to an implementation of the observer pattern. Another problem is the fact that C# methods are not virtual by default while Java methods are. Additionally, Java doesn't have a way to make methods non virtual. This creates another problem: an application in C# could leverage non virtual method behavior through polymorphism in a way the does not translate directly to Java. If you look around you will probably find that there are lots of tools to convert Java to C# since it is a simpler language (please don't flame me I didn't say worse I said simpler); however, you will find very few if any decent tools that convert C# to Java.
I would recommend changing your approach to converting from Java to C# as it will create fewer headaches in the long run. Db4Objects recently released their internal tool which they use to convert Db4o into C# to the public. It is called Sharpen. If you register with their site you can view this link with instructions on how to use Sharpen: http://developer.db4o.com/Resources/view.aspx/Reference/Sharpen/How_To_Setup_Sharpen
(I've been registered with them for a while and they're good about not spamming)

I don't know if this solves your problem but instead of:
$("#tbIntervalos").find("td").attr("id", horaInicial);
you can just do:
$("#tbIntervalos td#" + horaInicial);
For Spring Boot 2.1.0 and later you can use
mvn spring-boot:run -Dspring-boot.run.profiles=foo,bar
libs and Assets folder in Android Studio:
Create libs folder inside app folder and Asset folder inside main in the project directory by exploring project directory.
Now come back to Android Studio and switch the combo box from Android to Project. enjoy...
Random number generation between 1000 and 9999 inclusive:
FLOOR(RAND(CHECKSUM(NEWID()))*(9999-1000+1)+1000)
"+1" - to include upper bound values(9999 for previous example)
Try deleting the meta data and rebuild project.
Use os.path.join
to concatenate the directory and file name:
for path, subdirs, files in os.walk(root):
for name in files:
print(os.path.join(path, name))
Note the usage of path
and not root
in the concatenation, since using root
would be incorrect.
In Python 3.4, the pathlib module was added for easier path manipulations. So the equivalent to os.path.join
would be:
pathlib.PurePath(path, name)
The advantage of pathlib
is that you can use a variety of useful methods on paths. If you use the concrete Path
variant you can also do actual OS calls through them, like changing into a directory, deleting the path, opening the file it points to and much more.
I had some trouble with $scope.$watch
but after a lot of testing I found out that my data-ng-model="User.UserName"
was badly named and after I changed it to data-ng-model="UserName"
everything worked fine. I expect it to be the .
in the name causing the issue.
You can just iterate over the data attributes like any other object to get keys and values, here's how to do it with $.each
:
$.each($('#myEl').data(), function(key, value) {
console.log(key);
console.log(value);
});
Post is the most secured along with SSL installed because its transmitted in the message body.
But all of these methods are insecure because the 7 bit protocol it uses underneath it is hack-able with escapement. Even through a level 4 web application firewall.
Sockets are no guarantee either... Even though its more secure in certain ways.
If you hava a fact png (1MB for 400x400 etc.):
__import__("importlib").import_module("PIL.Image").open("out.png").save("out.png")
All the solutions provided force you to know the element you will click beforehand. If you want to get the class from any element clicked you can use:
$(document).on('click', function(e) {
clicked_id = e.target.id;
clicked_class = $('#' + e.target.id).attr('class');
// do stuff with ids and classes
})
I installed IntelliJ IDEA community version from http://www.jetbrains.com/idea/download/
I tried opening my project that I started in Android studio but it failed when at gradle build. I instead opened both android studio and intellij at same time and placed one screen next to the other and simply drag and dropped my java files, xml layouts, drawables, and manifest into the project hiearchy of a new project started in IntelliJ. It worked around the gradle build issues and now I can start a new project in IntelliJ and design either an android app or a basic Java app. Thankfully this worked because I hated having so many IDEs on my pc.
For arbitrary values, something like this works for 2.x
from string import ascii_uppercase as uc, ascii_lowercase as lc, maketrans
rotate = 13 # ROT13
rot = "".join([(x[:rotate][::-1] + x[rotate:][::-1])[::-1] for x in (uc,lc)])
def rot_func(text, encode=True):
ascii = uc + lc
src, trg = (ascii, rot) if encode else (rot, ascii)
trans = maketrans(src, trg)
return text.translate(trans)
text = "Text to ROT{}".format(rotate)
encode = rot_func(text)
decode = rot_func(encode, False)
I remember I had the same problem a while back using WCF due the quantity of the data I was passing. I remember I changed timeouts everywhere but the problem persisted. What I finally did was open the connection as stream request, I needed to change the client and the server side, but it work that way. Since it was a stream connection, the server kept reading until the stream ended.
I'll take a stab at it:
/^[a-z](?:_?[a-z0-9]+)*$/i
Explained:
/
^ # match beginning of string
[a-z] # match a letter for the first char
(?: # start non-capture group
_? # match 0 or 1 '_'
[a-z0-9]+ # match a letter or number, 1 or more times
)* # end non-capture group, match whole group 0 or more times
$ # match end of string
/i # case insensitive flag
The non-capture group takes care of a) not allowing two _
's (it forces at least one letter or number per group) and b) only allowing the last char to be a letter or number.
Some test strings:
"a": match
"_": fail
"zz": match
"a0": match
"A_": fail
"a0_b": match
"a__b": fail
"a_1_c": match

Original Answer (replaced with the above on 4 December 2015)
basically
protected void Application_BeginRequest(Object sender, EventArgs e)
{
if (HttpContext.Current.Request.IsSecureConnection.Equals(false) && HttpContext.Current.Request.IsLocal.Equals(false))
{
Response.Redirect("https://" + Request.ServerVariables["HTTP_HOST"]
+ HttpContext.Current.Request.RawUrl);
}
}
that would go in the global.asax.cs (or global.asax.vb)
i dont know of a way to specify it in the web.config
As Apple DOC
targetForAction:withSender:
Returns the target object that responds to an action.
You can't use that method to set target for UIButton
.
Try
addTarget(_:action:forControlEvents:) method
I have XAMPP 1.8.3-0 and PHP 5.5.0 installed.
1) edit php.ini:
from
;extension=php_intl.dll
to
extension=php_intl.dll
Note: After modification, need to save the file(php.ini) as well as need to restart the Apache Server.
2) Simply copy all icu* * * *.dll files:
from
C:\xampp\php
to
C:\xampp\apache\bin
Then intl extension works!!!
Without actually seeing your output file for confirmation, my guess is that you've got to get rid of the FIELDS ESCAPED BY
value.
MySQL's FIELDS ESCAPED BY
is probably behaving in two ways that you were not counting on: (1) it is only meant to be one character, so in your case it is probably equal to just one quotation mark; (2) it is used to precede each character that MySQL thinks needs escaping, including the FIELDS TERMINATED BY
and LINES TERMINATED BY
values. This makes sense to most of the computing world, but it isn't the way Excel does escaping.
I think your double REPLACE
is working, and that you are successfully replacing literal newlines with spaces (two spaces in the case of Windows-style newlines). But if you have any commas in your data (literals, not field separators), these are being preceded by quotation marks, which Excel treats much differently than MySQL. If that's the case, then the erroneous newlines that are tripping up Excel are actually newlines that MySQL had intended as line terminators.
Performance testing became something of a buzzword as of late but that’s not to say that performance testing is not an important process in QA or even after the product has shipped. And while I develop the app I use many different tools, some of them mentioned above like the chrome Profiler I usually look at a SaaS or something opensource that I can get going and forget about it until I get that alert saying that something went belly up.
There are lots of awesome tools that will help you keep an eye on performance without having you jump through hoops just to get some basics alerts set up. Here are a few that I think are worth checking out for yourself.
To try and paint a clearer picture, here is a little tutorial on how to set up monitoring for a react application.
If I assume data is the name of your dataframe, you can do :
data['race'].value_counts()
this will show you the distinct element and their number of occurence.
Use the wildcard "#" but beware that at some point you will have to somehow understand the data passing through the bus!
Try the following-sibling
axis (following-sibling::td
).
Here's one approach:
SELECT cur.textID, cur.fromEmail, cur.subject,
cur.timestamp, cur.read
FROM incomingEmails cur
LEFT JOIN incomingEmails next
on cur.fromEmail = next.fromEmail
and cur.timestamp < next.timestamp
WHERE next.timestamp is null
and cur.toUserID = '$userID'
ORDER BY LOWER(cur.fromEmail)
Basically, you join the table on itself, searching for later rows. In the where clause you state that there cannot be later rows. This gives you only the latest row.
If there can be multiple emails with the same timestamp, this query would need refining. If there's an incremental ID column in the email table, change the JOIN like:
LEFT JOIN incomingEmails next
on cur.fromEmail = next.fromEmail
and cur.id < next.id
Hibernate can create a table, hibernate sequence and tables used for many-to-many mapping on your behalf but you have to explicitly configure it by calling setProperty("hibernate.hbm2ddl.auto", "create") of the Configuration object. By Default, it just validates the schema with DB and fails if anything not already exists by giving error "ORA-00942: table or view does not exist".
If you do above configuration then order of performed actions will be:- a) Drop all tables and sequence and do not give an error if they are not already present. b) create all table and sequence c) alter tables with constraints d) insert data into it.
Awk is a good option if you have to deal with trailing whitespace because it'll take care of it for you:
echo " word1 word2 " | awk '{print $1;}' # Prints "word1"
Cut won't take care of this though:
echo " word1 word2 " | cut -f 1 -d " " # Prints nothing/whitespace
'cut' here prints nothing/whitespace, because the first thing before a space was another space.
For a typical example of employees owning one or more phones, see this wikibook section.
For your specific example, if you want to do a one-to-one
relationship, you should change the next code in ReleaseDateType model:
@Column(nullable = true)
private Integer media_Id;
for:
@OneToOne(fetch = FetchType.LAZY)
@JoinColumn(name="CACHE_MEDIA_ID", nullable=true)
private CacheMedia cacheMedia ;
and in CacheMedia model you need to add:
@OneToOne(cascade=ALL, mappedBy="ReleaseDateType")
private ReleaseDateType releaseDateType;
then in your repository you should replace:
@Query("Select * from A a left join B b on a.id=b.id")
public List<ReleaseDateType> FindAllWithDescriptionQuery();
by:
//In this case a query annotation is not need since spring constructs the query from the method name
public List<ReleaseDateType> findByCacheMedia_Id(Integer id);
or by:
@Query("FROM ReleaseDateType AS rdt WHERE cm.rdt.cacheMedia.id = ?1") //This is using a named query method
public List<ReleaseDateType> FindAllWithDescriptionQuery(Integer id);
Or if you prefer to do a @OneToMany
and @ManyToOne
relation, you should change the next code in ReleaseDateType model:
@Column(nullable = true)
private Integer media_Id;
for:
@OneToMany(cascade=ALL, mappedBy="ReleaseDateType")
private List<CacheMedia> cacheMedias ;
and in CacheMedia model you need to add:
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="RELEASE_DATE_TYPE_ID", nullable=true)
private ReleaseDateType releaseDateType;
then in your repository you should replace:
@Query("Select * from A a left join B b on a.id=b.id")
public List<ReleaseDateType> FindAllWithDescriptionQuery();
by:
//In this case a query annotation is not need since spring constructs the query from the method name
public List<ReleaseDateType> findByCacheMedias_Id(Integer id);
or by:
@Query("FROM ReleaseDateType AS rdt LEFT JOIN rdt.cacheMedias AS cm WHERE cm.id = ?1") //This is using a named query method
public List<ReleaseDateType> FindAllWithDescriptionQuery(Integer id);
Since React 16.8 in 2019 with useState and useEffect Hooks, following are now equivalent (in simple cases):
AngularJS:
$scope.name = 'misko'
$scope.$watch('name', getSearchResults)
<input ng-model="name" />
React:
const [name, setName] = useState('misko')
useEffect(getSearchResults, [name])
<input value={name} onChange={e => setName(e.target.value)} />
Since originally writing this answer, a new specification has reached recommendation status thanks to the W3C. The Page Visibility API (on MDN) now allows us to more accurately detect when a page is hidden to the user.
document.addEventListener("visibilitychange", onchange);
Current browser support:
The following code falls back to the less reliable blur/focus method in incompatible browsers:
(function() {
var hidden = "hidden";
// Standards:
if (hidden in document)
document.addEventListener("visibilitychange", onchange);
else if ((hidden = "mozHidden") in document)
document.addEventListener("mozvisibilitychange", onchange);
else if ((hidden = "webkitHidden") in document)
document.addEventListener("webkitvisibilitychange", onchange);
else if ((hidden = "msHidden") in document)
document.addEventListener("msvisibilitychange", onchange);
// IE 9 and lower:
else if ("onfocusin" in document)
document.onfocusin = document.onfocusout = onchange;
// All others:
else
window.onpageshow = window.onpagehide
= window.onfocus = window.onblur = onchange;
function onchange (evt) {
var v = "visible", h = "hidden",
evtMap = {
focus:v, focusin:v, pageshow:v, blur:h, focusout:h, pagehide:h
};
evt = evt || window.event;
if (evt.type in evtMap)
document.body.className = evtMap[evt.type];
else
document.body.className = this[hidden] ? "hidden" : "visible";
}
// set the initial state (but only if browser supports the Page Visibility API)
if( document[hidden] !== undefined )
onchange({type: document[hidden] ? "blur" : "focus"});
})();
onfocusin
and onfocusout
are required for IE 9 and lower, while all others make use of onfocus
and onblur
, except for iOS, which uses onpageshow
and onpagehide
.
A query of type MyEntity
is going to return MyEntity
. You want a query for a Long
.
CriteriaBuilder qb = entityManager.getCriteriaBuilder();
CriteriaQuery<Long> cq = qb.createQuery(Long.class);
cq.select(qb.count(cq.from(MyEntity.class)));
cq.where(/*your stuff*/);
return entityManager.createQuery(cq).getSingleResult();
Obviously you will want to build up your expression with whatever restrictions and groupings etc you skipped in the example.
If this is for showing a time of day to a user, then in at least 19 out of 20 you don’t need to care about kk
, HH
nor hh
. I suggest that you use something like this:
DateTimeFormatter defaultTimeFormatter
= DateTimeFormatter.ofLocalizedTime(FormatStyle.SHORT);
System.out.format("%s: %s%n",
Locale.getDefault(), LocalTime.MIN.format(defaultTimeFormatter));
The point is that it gives different output in different default locales. For example:
en_SS: 12:00 AM fr_BL: 00:00 ps_AF: 0:00 es_CO: 12:00 a.m.
The localized formats have been designed to conform with the expectations of different cultures. So they generally give the user a better experience and they save you of writing a format pattern string, which is always error-prone.
I furthermore suggest that you don’t use SimpleDateFormat
. That class is notoriously troublesome and fortunately long outdated. Instead I use java.time, the modern Java date and time API. It is so much nicer to work with.
Of course if you need to parse a string with a specified format, and also if you have a very specific formatting requirement, it’s good to use a format pattern string. There are actually four different pattern letters to choose from for hour (quoted from the documentation):
Symbol Meaning Presentation Examples
------ ------- ------------ -------
h clock-hour-of-am-pm (1-12) number 12
K hour-of-am-pm (0-11) number 0
k clock-hour-of-day (1-24) number 24
H hour-of-day (0-23) number 0
In practice H
and h
are used. As far as I know k
and K
are not (they may just have been included for the sake of completeness). But let’s just see them all in action:
DateTimeFormatter timeFormatter
= DateTimeFormatter.ofPattern("hh:mm a HH:mm kk:mm KK:mm a", Locale.ENGLISH);
System.out.println(LocalTime.of(0, 0).format(timeFormatter));
System.out.println(LocalTime.of(1, 15).format(timeFormatter));
System.out.println(LocalTime.of(11, 25).format(timeFormatter));
System.out.println(LocalTime.of(12, 35).format(timeFormatter));
System.out.println(LocalTime.of(13, 40).format(timeFormatter));
12:00 AM 00:00 24:00 00:00 AM 01:15 AM 01:15 01:15 01:15 AM 11:25 AM 11:25 11:25 11:25 AM 12:35 PM 12:35 12:35 00:35 PM 01:40 PM 13:40 13:40 01:40 PM
If you don’t want the leading zero, just specify one pattern letter, that is h
instead of hh
or H
instead of HH
. It will still accept two digits when parsing, and if a number to be printed is greater than 9, two digits will still be printed.
DateTimeFormatter
.Dot is a dereference operator and used to connect the structure variable for a particular record of structure. Eg :
struct student
{
int s.no;
Char name [];
int age;
} s1,s2;
main()
{
s1.name;
s2.name;
}
In such way we can use a dot operator to access the structure variable
Try this out
string abc = ConfigurationManager.ConnectionStrings["CharityManagement"].ConnectionString;
The simplest is using the OpenCV Mat class:
img=cv::Scalar(blue_value, green_value, red_value);
where img
was defined as a cv::Mat
.
I think we could write in the following way to retrieve(below code is just an example, please modify as needed):
Create FUNCTION dbo.ufnGetEmployeeMultiple(@DepartmentID int)
RETURNS VARCHAR(1000) AS
BEGIN
DECLARE @Employeelist varchar(1000)
SELECT @Employeelist = COALESCE(@Employeelist + ', ', '') + E.LoginID
FROM humanresources.Employee E
Left JOIN humanresources.EmployeeDepartmentHistory H ON
E.BusinessEntityID = H.BusinessEntityID
INNER JOIN HumanResources.Department D ON
H.DepartmentID = D.DepartmentID
Where H.DepartmentID = @DepartmentID
Return @Employeelist
END
SELECT D.name as Department, dbo.ufnGetEmployeeMultiple (D.DepartmentID)as Employees
FROM HumanResources.Department D
SELECT Distinct (D.name) as Department, dbo.ufnGetEmployeeMultiple (D.DepartmentID) as
Employees
FROM HumanResources.Department D
Use this because whenever transaction open more than one transaction then below will work SELECT * FROM sys.sysprocesses WHERE open_tran <> 0
To find rows where col is NULL
, empty string or whitespace (spaces, tabs):
SELECT *
FROM table
WHERE ISNULL(LTRIM(RTRIM(col)),'')=''
To find rows where col is NOT NULL
, empty string or whitespace (spaces, tabs):
SELECT *
FROM table
WHERE ISNULL(LTRIM(RTRIM(col)),'')<>''
I changed a bit and it worked like this, dumped into one single array, provided all the images are of same dimensions.
png = []
for image_path in glob.glob("./train/*.png"):
png.append(misc.imread(image_path))
im = np.asarray(png)
print 'Importing done...', im.shape
var json = { ... };
var key = "foo";
delete json[key]; // Removes json.foo from the dictionary.
You can use splice to remove elements from an array.
Node.js nanotimer
I wrote a wrapper library/object for node.js on top of the process.hrtime
function call. It has useful functions, like timing synchronous and asynchronous tasks, specified in seconds, milliseconds, micro, or even nano, and follows the syntax of the built in javascript timer so as to be familiar.
Timer objects are also discrete, so you can have as many as you'd like, each with their own setTimeout
or setInterval
process running.
It's called nanotimer. Check it out!
In Typescript and ES6 you can also use for..of:
for (var product of products) {
console.log(product.product_desc)
}
which will be transcoded to javascript:
for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
var product = products_1[_i];
console.log(product.product_desc);
}
In addition to the accepted answers above I created a generic 'groupBy' filter using the underscore.js library.
JSFiddle (updated): http://jsfiddle.net/TD7t3/
The filter
app.filter('groupBy', function() {
return _.memoize(function(items, field) {
return _.groupBy(items, field);
}
);
});
Note the 'memoize' call. This underscore method caches the result of the function and stops angular from evaluating the filter expression every time, thus preventing angular from reaching the digest iterations limit.
The html
<ul>
<li ng-repeat="(team, players) in teamPlayers | groupBy:'team'">
{{team}}
<ul>
<li ng-repeat="player in players">
{{player.name}}
</li>
</ul>
</li>
</ul>
We apply our 'groupBy' filter on the teamPlayers scope variable, on the 'team' property. Our ng-repeat receives a combination of (key, values[]) that we can use in our following iterations.
Update June 11th 2014 I expanded the group by filter to account for the use of expressions as the key (eg nested variables). The angular parse service comes in quite handy for this:
The filter (with expression support)
app.filter('groupBy', function($parse) {
return _.memoize(function(items, field) {
var getter = $parse(field);
return _.groupBy(items, function(item) {
return getter(item);
});
});
});
The controller (with nested objects)
app.controller('homeCtrl', function($scope) {
var teamAlpha = {name: 'team alpha'};
var teamBeta = {name: 'team beta'};
var teamGamma = {name: 'team gamma'};
$scope.teamPlayers = [{name: 'Gene', team: teamAlpha},
{name: 'George', team: teamBeta},
{name: 'Steve', team: teamGamma},
{name: 'Paula', team: teamBeta},
{name: 'Scruath of the 5th sector', team: teamGamma}];
});
The html (with sortBy expression)
<li ng-repeat="(team, players) in teamPlayers | groupBy:'team.name'">
{{team}}
<ul>
<li ng-repeat="player in players">
{{player.name}}
</li>
</ul>
</li>

The documentation of MySQL says :
CREATE DATABASE creates a database with the given name. To use this statement, you need the CREATE privilege for the database. CREATE SCHEMA is a synonym for CREATE DATABASE as of MySQL 5.0.2.
So, it would seem normal that those two instruction do the same.
// calculating the difference b/w startDate and endDate
String startDate = "01-01-2016";
String endDate = simpleDateFormat.format(currentDate);
date1 = simpleDateFormat.parse(startDate);
date2 = simpleDateFormat.parse(endDate);
long getDiff = date2.getTime() - date1.getTime();
// using TimeUnit class from java.util.concurrent package
long getDaysDiff = TimeUnit.MILLISECONDS.toDays(getDiff);
You can use a css3 psuedo element (:before
and/or :after
) as shown in this article
https://www.exratione.com/2011/09/how-to-overflow-a-background-image-using-css3/
Good Luck...
You can create an array of pointers.
Car** mycars = new Car*[userInput];
for (int i=0; i<userInput; i++){
mycars[i] = new Car(...);
}
...
for (int i=0; i<userInput; i++){
delete mycars[i];
}
delete [] mycars;
or
Car() constructor does not need to be public. Add a static method to your class that builds an array:
static Car* makeArray(int length){
return new Car[length];
}
If you have a module with a class you want to import, you can do it like this.
module = __import__(filename)
instance = module.MyClass()
If you do not know what the class is named, you can iterate through the classes available from a module.
import inspect
module = __import__(filename)
for c in module.__dict__.values():
if inspect.isclass(c):
# You may need do some additional checking to ensure
# it's the class you want
instance = c()
You can also do this
public class Example extends Activity {
final Context context = this;
final Dialog dialog = new Dialog(context);
}
This worked for me !!
I tried to use socket.io on AWS, I can at most keep around 600 connections stable.
And I found out it is because socket.io used long polling first and upgraded to websocket later.
after I set the config to use websocket only, I can keep around 9000 connections.
Set this config at client side:
const socket = require('socket.io-client')
const conn = socket(host, { upgrade: false, transports: ['websocket'] })
public class GoogleSearch {
public static void main(String[] args) {
WebDriver driver=new FirefoxDriver();
driver.get("http://www.google.com");
driver.findElement(By.xpath("//input[@type='text']")).sendKeys("Cheese");
driver.findElement(By.xpath("//button[@name='btnG']")).click();
driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
driver.findElement(By.xpath("(//h3[@class='r']/a)[3]")).click();
driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
}
}
None of the other answers were working for me. I ended up creating a function within my iframe that returns the object I was looking for:
function getElementWithinIframe() {
return document.getElementById('copy-sheet-form');
}
Then you call that function like so to retrieve the element:
var el = document.getElementById("iframeId").contentWindow.functionNameToCall();
From Chorme v81 the params --user-data-dir=
requires an actual parameter, whereas in the past it didn't.
Something like this works fine for me

I think that for SQL Server Local Db you shouldn't use the Initial Catalog
property.
I suggest to use:
<add name="DefaultConnection"
connectionString="Data Source=(LocalDb)\v11.0;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\OdeToFoodDb.mdf"
providerName="System.Data.SqlClient" />
I think that local db doesn't support multiple database on the same mdf file so specify an initial catalog is not supported (or not well supported and I have some strange errors).
If you are using PHP >= 5.1.0 Just do something like this with the ErrorException class:
<?php
// Define an error handler
function exception_error_handler($errno, $errstr, $errfile, $errline ) {
throw new ErrorException($errstr, $errno, 0, $errfile, $errline);
}
// Set your error handler
set_error_handler("exception_error_handler");
/* Trigger exception */
try
{
// Try to do something like finding the end of the internet
}
catch(ErrorException $e)
{
// Anything you want to do with $e
}
?>
On http://www.synalysis.net/ you can get the hex editor I'm developing for the Mac - Synalyze It!. It costs 7 € / 40 € (Pro version) and offers some extra features like histogram, incremental search, support of many text encodings and interactive definition of a "grammar" for your file format.
The grammar helps to interpret the files and colors the hex view for easier analysis.

You can create a temp folder, move all the files and sub-folders you want to keep into the temp folder then delete the old folder and rename the temp folder to the old folder try this example until you are confident to do it live:
mkdir testit
cd testit
mkdir big_folder tmp_folder
touch big_folder/file1.pdf
touch big_folder/file2.pdf
mv big_folder/file1,pdf tmp_folder/
rm -r big_folder
mv tmp_folder big_folder
the rm -r big_folder
will remove all files in the big_folder
no matter how many. You just have to be super careful you first have all the files/folders you want to keep, in this case it was file1.pdf

Download and install Eclipse, and you're good to go.
http://www.eclipse.org/downloads/
Apple provides its own version of Java, so make sure it's up-to-date.
http://developer.apple.com/java/download/
Eclipse is an integrated development environment. It has many features, but the ones that are relevant for you at this stage is:
As you gain more experience, you'll start to appreciate the rest of its rich set of features.
The inconvenience of typing 10 < x && x < 20
is minimal compared to the increase in language complexity if one would allow 10 < x < 20
, so the designers of the Java language decided against supporting it.
This is not only a 'newbie' scenario. I just ran across this compiler message (GCC 5.4) when refactoring a class to remove some constructor parameters. I forgot to update both the declaration and definition, and the compiler spit out this unintuitive error.
The bottom line seems to be this: If the compiler can't match the definition's signature to the declaration's signature it thinks the definition is not a constructor and then doesn't know how to parse the code and displays this error. Which is also what happened for the OP: std::string
is not the same type as string
so the declaration's signature differed from the definition's and this message was spit out.
As a side note, it would be nice if the compiler looked for almost-matching constructor signatures and upon finding one suggested that the parameters didn't match rather than giving this message.
If you are feeling particularly clever and don't want to use Regex:
char[] separators = new char[]{' ',';',',','\r','\t','\n'};
string s = "this;is,\ra\t\n\n\ntest";
string[] temp = s.Split(separators, StringSplitOptions.RemoveEmptyEntries);
s = String.Join("\n", temp);
You could wrap this in an extension method with little effort as well.
Edit: Or just wait 2 minutes and I'll end up writing it anyway :)
public static class ExtensionMethods
{
public static string Replace(this string s, char[] separators, string newVal)
{
string[] temp;
temp = s.Split(separators, StringSplitOptions.RemoveEmptyEntries);
return String.Join( newVal, temp );
}
}
And voila...
char[] separators = new char[]{' ',';',',','\r','\t','\n'};
string s = "this;is,\ra\t\n\n\ntest";
s = s.Replace(separators, "\n");
Here's a non-standard but cross-browser method that may be useful if you don't want to pass any arguments:-
Html:
<div onclick=myHandler() id="my element's id">→ Click Here! ←</div>
Script:
function myHandler(){
alert(myHandler.caller.arguments[0].target.id)
}
You can try this one
function isPrime(num){_x000D_
_x000D_
// Less than or equal to 1 are not prime_x000D_
if (num<=1) return false;_x000D_
_x000D_
// 2 and 3 are prime, so no calculations_x000D_
if (num==2 || num==3 ) return true; _x000D_
_x000D_
// If mod with square root is zero then its not prime _x000D_
if (num % Math.sqrt(num)==0 ) return false;_x000D_
_x000D_
// Run loop till square root_x000D_
for(let i = 2, sqrt = Math.sqrt(num); i <= sqrt; i++) {_x000D_
_x000D_
// If mod is zero then its not prime_x000D_
if(num % i === 0) return false; _x000D_
}_x000D_
_x000D_
// Otherwise the number is prime_x000D_
return true;_x000D_
}_x000D_
_x000D_
_x000D_
for(let i=-2; i <= 35; i++) { _x000D_
console.log(`${i} is${isPrime(i) ? '' : ' not'} prime`);_x000D_
}
_x000D_
Here's a one-liner using Maven:
mvn dependency:get -Dartifact=mysql:mysql-connector-java:5.1.38
Then, with default settings, it's available in:
$HOME/.m2/repository/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar
Just replace the version number if you need a different one.

David Crawshaw project(sqlitejdbc-v056.jar) seems out of date and last update was Jun 20, 2009, source here
I would recomend Xerials fork of Crawshaw sqlite wrapper. I replaced sqlitejdbc-v056.jar with Xerials sqlite-jdbc-3.7.2.jar file without any problem.
Uses same syntax as in Bernie's answer and is much faster and with latest sqlite library.
What is different from Zentus's SQLite JDBC?
The original Zentus's SQLite JDBC driver http://www.zentus.com/sqlitejdbc/ itself is an excellent utility for using SQLite databases from Java language, and our SQLiteJDBC library also relies on its implementation. However, its pure-java version, which totally translates c/c++ codes of SQLite into Java, is significantly slower compared to its native version, which uses SQLite binaries compiled for each OS (win, mac, linux).
To use the native version of sqlite-jdbc, user had to set a path to the native codes (dll, jnilib, so files, which are JNDI C programs) by using command-line arguments, e.g., -Djava.library.path=(path to the dll, jnilib, etc.), or -Dorg.sqlite.lib.path, etc. This process was error-prone and bothersome to tell every user to set these variables. Our SQLiteJDBC library completely does away these inconveniences.
Another difference is that we are keeping this SQLiteJDBC libray up-to-date to the newest version of SQLite engine, because we are one of the hottest users of this library. For example, SQLite JDBC is a core component of UTGB (University of Tokyo Genome Browser) Toolkit, which is our utility to create personalized genome browsers.
EDIT : As usual when you update something, there will be problems in some obscure place in your code(happened to me). Test test test =)
Another way to go about it, besides the nice answers already mentioned, depends upon the fact that you can pass optional named arguments by position. For example,
def f(x,y=None):
print(x)
if y is not None:
print(y)
Yields
In [11]: f(1,2)
1
2
In [12]: f(1)
1
It is real simple. Just use:
df.columns = ['Name1', 'Name2', 'Name3'...]
And it will assign the column names by the order you put them in.
This will work:
ALTER TABLE [dbo].[company] DROP CONSTRAINT [Company_CountryID_FK]

I have always tested the number of open workbooks in Workbook_Open(). If it is 1, then the workbook was opened by the command line (or the user closed all the workbooks, then opened this one).
If Workbooks.Count = 1 Then
' execute the macro or call another procedure - I always do the latter

ThisWorkbook.Save
Application.Quit
End If
I had a situation where I needed to obtain the next available key in an array, which is the highest+1.
For example, if the array is $data=['1'=>'something,'34'=>'something else'] then I needed to calculate 35 to add a new element to the array that had a key higher than any of the others. In the case of an empty array I needed 1 as next available key.
This is the solution that worked:
$highest = 0;
foreach($data as $idx=>$dummy)
{
if($idx > $highest)$highest=$idx;
}
$highest++;
It will work in all cases, empty array or not. If you only need to find the highest key rather than highest key + 1, delete the last line. You will then get a value of 0 if the array is empty.
WebSphere Application Server V7 does support Java Platform, Standard Edition (Java SE) 6 (see Specifications and API documentation in the Network Deployment (All operating systems), Version 7.0 Information Center) and it's since the release V8.5 when Java 7 has been supported.
I couldn't find the Java 6 SDK documentation, and could only consult IBM JVM Messages in Java 7 Windows documentation. Alas, I couldn't find the error message in the documentation either.
Since java.lang.UnsupportedClassVersionError is "Thrown when the Java Virtual Machine attempts to read a class file and determines that the major and minor version numbers in the file are not supported.", you ran into an issue of building the application with more recent version of Java than the one supported by the runtime environment, i.e. WebSphere Application Server 7.0.
I may be mistaken, but I think that offset=6 in the message is to let you know what position caused the incompatibility issue to occur. It's irrelevant for you, for me, and for many other people, but some might find it useful, esp. when they generate bytecode themselves.

Answered my own question:
IPv6 addresses are normally written as eight groups of four hexadecimal digits, where each group is separated by a colon (:).
So that's 39 characters max.
For security code, please don't generate your tokens this way: $token = md5(uniqid(rand(), TRUE));
rand()
is predictableuniqid()
only adds up to 29 bits of entropymd5()
doesn't add entropy, it just mixes it deterministicallyTry this out:
session_start();
if (empty($_SESSION['token'])) {
$_SESSION['token'] = bin2hex(random_bytes(32));
}
$token = $_SESSION['token'];
Sidenote: One of my employer's open source projects is an initiative to backport random_bytes()
and random_int()
into PHP 5 projects. It's MIT licensed and available on Github and Composer as paragonie/random_compat.
session_start();
if (empty($_SESSION['token'])) {
if (function_exists('mcrypt_create_iv')) {
$_SESSION['token'] = bin2hex(mcrypt_create_iv(32, MCRYPT_DEV_URANDOM));
} else {
$_SESSION['token'] = bin2hex(openssl_random_pseudo_bytes(32));
}
}
$token = $_SESSION['token'];
Don't just use ==
or even ===
, use hash_equals()
(PHP 5.6+ only, but available to earlier versions with the hash-compat library).
if (!empty($_POST['token'])) {
if (hash_equals($_SESSION['token'], $_POST['token'])) {
// Proceed to process the form data
} else {
// Log this as a warning and keep an eye on these attempts
}
}
You can further restrict tokens to only be available for a particular form by using hash_hmac()
. HMAC is a particular keyed hash function that is safe to use, even with weaker hash functions (e.g. MD5). However, I recommend using the SHA-2 family of hash functions instead.
First, generate a second token for use as an HMAC key, then use logic like this to render it:
<input type="hidden" name="token" value="<?php
echo hash_hmac('sha256', '/my_form.php', $_SESSION['second_token']);
?>" />
And then using a congruent operation when verifying the token:
$calc = hash_hmac('sha256', '/my_form.php', $_SESSION['second_token']);
if (hash_equals($calc, $_POST['token'])) {
// Continue...
}
The tokens generated for one form cannot be reused in another context without knowing $_SESSION['second_token']
. It is important that you use a separate token as an HMAC key than the one you just drop on the page.
Anyone who uses the Twig templating engine can benefit from a simplified dual strategy by adding this filter to their Twig environment:
$twigEnv->addFunction(
new \Twig_SimpleFunction(
'form_token',
function($lock_to = null) {
if (empty($_SESSION['token'])) {
$_SESSION['token'] = bin2hex(random_bytes(32));
}
if (empty($_SESSION['token2'])) {
$_SESSION['token2'] = random_bytes(32);
}
if (empty($lock_to)) {
return $_SESSION['token'];
}
return hash_hmac('sha256', $lock_to, $_SESSION['token2']);
}
)
);
With this Twig function, you can use both the general purpose tokens like so:
<input type="hidden" name="token" value="{{ form_token() }}" />
Or the locked down variant:
<input type="hidden" name="token" value="{{ form_token('/my_form.php') }}" />
Twig is only concerned with template rendering; you still must validate the tokens properly. In my opinion, the Twig strategy offers greater flexibility and simplicity, while maintaining the possibility for maximum security.
If you have a security requirement that each CSRF token is allowed to be usable exactly once, the simplest strategy regenerate it after each successful validation. However, doing so will invalidate every previous token which doesn't mix well with people who browse multiple tabs at once.
Paragon Initiative Enterprises maintains an Anti-CSRF library for these corner cases. It works with one-use per-form tokens, exclusively. When enough tokens are stored in the session data (default configuration: 65535), it will cycle out the oldest unredeemed tokens first.
The general rule-of-thumb is, if you can do it using a single SQL statement instead of using PL/SQL, you should. It will usually be more efficient.
However, if you need to add more procedural logic (for some reason), you might need to use PL/SQL, but you should use bulk operations instead of row-by-row processing. (Note: in Oracle 10g and later, your FOR loop will automatically use BULK COLLECT to fetch 100 rows at a time; however your insert statement will still be done row-by-row).
e.g.
DECLARE
TYPE tA IS TABLE OF FOO.A%TYPE INDEX BY PLS_INTEGER;
TYPE tB IS TABLE OF FOO.B%TYPE INDEX BY PLS_INTEGER;
TYPE tC IS TABLE OF FOO.C%TYPE INDEX BY PLS_INTEGER;
rA tA;
rB tB;
rC tC;
BEGIN
SELECT * BULK COLLECT INTO rA, rB, rC FROM FOO;
-- (do some procedural logic on the data?)
FORALL i IN rA.FIRST..rA.LAST
INSERT INTO BAR(A,
B,
C)
VALUES(rA(i),
rB(i),
rC(i));
END;
The above has the benefit of minimising context switches between SQL and PL/SQL. Oracle 11g also has better support for tables of records so that you don't have to have a separate PL/SQL table for each column.
Also, if the volume of data is very great, it is possible to change the code to process the data in batches.
An alternative approach, which I've recently implemented, is to use the div-table plugin with panflute.
This creates a table from a set of fenced divs (standard in the pandoc implementation of markdown), in a similar layout to html:
---
panflute-filters: [div-table]
panflute-path: 'panflute/docs/source'
---
::::: {.divtable}
:::: {.tcaption}
a caption here (optional), only the first paragraph is used.
::::
:::: {.thead}
[Header 1]{width=0.4 align=center}
[Header 2]{width=0.6 align=default}
::::
:::: {.trow}
::: {.tcell}
1. any
2. normal markdown
3. can go in a cell
:::
::: {.tcell}

some text

If bypara=true
Then each paragraph will be treated as a separate column

any text outside a div will be ignored

Looks like:
Maybe you could take a look at JFileChooser, which allow you to use native dialogs in one line of code.
Before JavaScript 1.5: ^[a-zA-Z_$][0-9a-zA-Z_$]*$
In English: It must start with a dollar sign, underscore or one of letters in the 26-character alphabet, upper or lower case. Subsequent characters (if any) can be one of any of those or a decimal digit.
JavaScript 1.5 and later * : ^[\p{L}\p{Nl}$_][\p{L}\p{Nl}$\p{Mn}\p{Mc}\p{Nd}\p{Pc}]*$
This is more difficult to express in English, but it is conceptually similar to the older syntax with the addition that the letters and digits can be from any language. After the first character, there are also allowed additional underscore-like characters (collectively called “connectors”) and additional character combining marks (“modifiers”). (Other currency symbols are not included in this extended set.)
JavaScript 1.5 and later also allows Unicode escape sequences, provided that the result is a character that would be allowed in the above regular expression.
Identifiers also must not be a current reserved word or one that is considered for future use.
There is no practical limit to the length of an identifier. (Browsers vary, but you’ll safely have 1000 characters and probably several more orders of magnitude than that.)
Links to the character categories:
*n.b. This Perl regex is intended to describe the syntax only — it won’t work in JavaScript, which doesn’t (yet) include support for Unicode Properties. (There are some third-party packages that claim to add such support.)
Initializing a vector having struct, class or Union can be done this way
std::vector<SomeStruct> someStructVect(length);
memset(someStructVect.data(), 0, sizeof(SomeStruct)*length);
The simplest and best way to get yesterday's date is:
subdate(current_date, 1)
Your query would be:
SELECT
url as LINK,
count(*) as timesExisted,
sum(DateVisited between UNIX_TIMESTAMP(subdate(current_date, 1)) and
UNIX_TIMESTAMP(current_date)) as timesVisitedYesterday
FROM mytable
GROUP BY 1
For the curious, the reason that sum(condition)
gives you the count of rows that satisfy the condition, which would otherwise require a cumbersome and wordy case
statement, is that in mysql boolean values are 1
for true and 0
for false, so summing a condition effectively counts how many times it's true. Using this pattern can neaten up your SQL code.
Use below to check file's size and clear if it's greater,
$("input[type='file']").on("change", function () {
if(this.files[0].size > 2000000) {
alert("Please upload file less than 2MB. Thanks!!");
$(this).val('');
}
});
Use Css Selector for this, or learn more about Css Selector just go here
https://www.w3schools.com/cssref/css_selectors.asp
#main_text > .title {
/* Style goes here */
}
#main_text .title {
/* Style goes here */
}
You can do it like this and you mod function will work perfect let me know if you want a code pen
<div ng-repeat="icon in icons">
<div class="row" ng-if="$index % 3 == 0 ">
<i class="col col-33 {{icons[$index + n].icon}} custom-icon"></i>
<i class="col col-33 {{icons[$index + n + 1].icon}} custom-icon"></i>
<i class="col col-33 {{icons[$index + n + 2].icon}} custom-icon"></i>
</div>
</div>
For a minimal change:
for(int i=0; i<str.Length; i++ )
if(str[i] >= 'a' && str[i] <= 'z' || str[i] >= 'A' && str[i] <= 'Z')
errorCount++;
You could use regular expressions, at least if speed is not an issue and you do not really need the actual exact count.
I faced a similar problem. I tried everything with ports, hosts and config files.But nothing helped.
I checked apache error logs. They showed the following error
(OS 10038)An operation was attempted on something that is not a socket. : AH00332: winnt_accept: getsockname error on listening socket, is IPv6 available?
Finally this is what solved my problem.
1) Goto command prompt and run it in administrative mode. In windows 7 you can do it by typing cmd
in run and then pressing ctrl+shift+enter
2) run the following command:
netsh winsock reset
3) Restart the system
I have mysql data folder replaced by a windows directory junction. I suspect ib_logfile0/1 and/or ibdata1 is corrupted.
Just try to delete those files and computername.err. Then restart mysql service. That's what I did, with success.
Copying ibdata1 files, after a full reinstallation of mysql, to the junction dir and replacing dir by the junction, restarting mysql, was not enough.
You have to let mysql rebuild those files.
I had the same its because of version incompatibility check for version or remove version if using spring boot
If you're using a variable when searching in a string, mysql_real_escape_string()
is good for you. Just my suggestion:
$char = "and way's 'hihi'";
$myvar = mysql_real_escape_string($char);
select * from tablename where fields like "%string $myvar %";
Try this:
private void txtEntry_KeyUp(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
string trimText;
trimText = this.txtEntry.Text.Replace("\r\n", "").ToString();
this.txtEntry.Text = trimText;
btnEnter.PerformClick();
}
}
I did a SQL query in a large number of OR (350). Postgres do it 437.80ms.
Now use IN:
23.18ms
All development is done using your choice of C#, Boo, or a dialect of JavaScript.
Most of the example code in the documentation is in JavaScript; if you poke around the official forums and wiki you'll see a pretty even mix of C# and Javascript. Very few people seem to use Boo, but it's just as good; pick the language you already know or are the happiest learning.
Unity takes your C#/JS/Boo code and compiles it to run on iOS, Android, PC, Mac, XBox, PS3, Wii, or web plugin. Depending on the platform that might end up being Objective C or something else, but that's completely transparent to you. There's really no benefit to knowing Objective C; you can't program in it.
Update 2019/31/01
Starting from Unity 2017.2 "UnityScript" (Unity's version of JavaScript, but not identical to) took its first step towards complete deprecation by removing the option to add a "JavaScript" file from the UI. Though JS files could still be used, support for it will completely be dropped in later versions.
This also means that Boo will become unusable as its compiler is actually built as a layer on top of UnityScript and will thus be removed as well.
This means that in the future only C# will have native support.
unity has released a full article on the deprecation of UnityScript and Boo back in August 2017.
Just to help out anyone that is having the same issue but specifically using Zsh shell with iTerm 2. It turns out that Zsh doesn't read /etc/inputrc
properly, and so fails to understand any key bindings you set up through the preferences!
To fix this, you need to add some key bindings to your .zshrc
file, such as:
# key bindings
bindkey "\e[1~" beginning-of-line
bindkey "\e[4~" end-of-line
Note the backslashes in the example above before the "e", the linked article does not show them, so add them into your .zshrc
file when adding bindings.
SELECT MAX(id) FROM TABELNAME
This identifies the largest id and returns the value
If you don't want to have to worry about Null value issues like checking for null every time you use it or wrapping it up in some logic, and you also don't want to have to worry about offset time issues, then this is how I solved the problem:
startDate = startDate <= DateTime.MinValue.AddSeconds(1) ? keepIt : resetIt
I just check that the defaulted value is less than a day after the beginning of time. Works like a charm.
Edit 2021: If you need to check milliseconds of the beginning of time then just add ticks instead, but also maybe carbon dating is what you are really looking for. Still not sure carbon dating would even be as accurate as you need if you need accuracy to the tick.
I like Hrishikesh's answer, to which I only have this to add...because we saw a comma-delimited string coming across when multiple proxies along the way were used, we found it necessary to add an explode and grab the final value, like this:
$IParray=array_values(array_filter(explode(',',$_SERVER['HTTP_X_FORWARDED_FOR'])));
return end($IParray);
the array_filter is in there to remove empty entries.
No, MSSQL doesn't allow such queries. You should use col LIKE '...' OR col LIKE '...'
etc.
You can also find the name of the current on screen activity using
adb shell dumpsys window windows | grep 'mCurrentFocus'
I tried re-creating this, and .someclass.notip
was being generated for me but .someclass:not(.notip)
was not, for as long as I did not have the @mixin tip()
defined. Once I had that, it all worked.
http://sassmeister.com/gist/9775949
$dropdown-width: 100px;
$comp-tip: true;
@mixin tip($pos:right) {
}
@mixin dropdown-pos($pos:right) {
&:not(.notip) {
@if $comp-tip == true{
@if $pos == right {
top:$dropdown-width * -0.6;
background-color: #f00;
@include tip($pos:$pos);
}
}
}
&.notip {
@if $pos == right {
top: 0;
left:$dropdown-width * 0.8;
background-color: #00f;
}
}
}
.someclass { @include dropdown-pos(); }
EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'.
it what I get when I remove @mixin tip($pos:right) { }
What is the package name of your class? If there is no package name, then most likely the solution is:
java -cp FileManagement Main
>>> names = ['King', 'Queen', 'Joker']
>>> any(n in 'King and john' for n in names)
True
>>> all(n in 'King and Queen' for n in names)
False
It just reduce several line of code into one. You don't have to write lengthy code like:
for n in names:
if n in 'King and john':
print True
else:
print False
If you just want to run the file, right click on the class from the package explorer, and click Run File, or (Alt + R, F), or (Shift + F6)
One thing that to be remembered while solving such problems is that in JSON file, a {
indicates a JSONObject
and a [
indicates JSONArray
. If one could manage them properly, it would be very easy to accomplish the task of parsing the JSON file. The above code was really very helpful for me and I hope this content adds some meaning to the above code.
The Gson JsonReader documentation explains how to handle parsing of JsonObjects
and JsonArrays
:
- Within array handling methods, first call beginArray() to consume the array's opening bracket. Then create a while loop that accumulates values, terminating when hasNext() is false. Finally, read the array's closing bracket by calling endArray().
- Within object handling methods, first call beginObject() to consume the object's opening brace. Then create a while loop that assigns values to local variables based on their name. This loop should terminate when hasNext() is false. Finally, read the object's closing brace by calling endObject().
SOAPAction is required in SOAP 1.1 but can be empty ("").
See https://www.w3.org/TR/2000/NOTE-SOAP-20000508/#_Toc478383528
"The header field value of empty string ("") means that the intent of the SOAP message is provided by the HTTP Request-URI."
Try setting SOAPAction=""
In addition to move_to_element()
and scrollIntoView()
I wanted to pose the following code which attempts to center the element in the view:
desired_y = (element.size['height'] / 2) + element.location['y']
window_h = driver.execute_script('return window.innerHeight')
window_y = driver.execute_script('return window.pageYOffset')
current_y = (window_h / 2) + window_y
scroll_y_by = desired_y - current_y
driver.execute_script("window.scrollBy(0, arguments[0]);", scroll_y_by)
Use Point data type to store Longitude and Latitude in a single column:
CREATE TABLE table_name (
id integer NOT NULL,
name text NOT NULL,
location point NOT NULL,
created_on timestamp with time zone NOT NULL DEFAULT CURRENT_TIMESTAMP,
CONSTRAINT table_name_pkey PRIMARY KEY (id)
)
Create an Indexing on a 'location' column :
CREATE INDEX ON table_name USING GIST(location);
GiST index is capable of optimizing “nearest-neighbor” search :
SELECT * FROM table_name ORDER BY location <-> point '(-74.013, 40.711)' LIMIT 10;
Note: The point first element is longitude and the second element is latitude.
For more info check this Query Operators.
Just to augment the accepted answer with a brief newbie-friendly short answer, you probably don't need exec
.
If you're still here, the following discussion should hopefully reveal why. When you run, say,
sh -c 'command'
you run a sh
instance, then start command
as a child of that sh
instance. When command
finishes, the sh
instance also finishes.
sh -c 'exec command'
runs a sh
instance, then replaces that sh
instance with the command
binary, and runs that instead.
Of course, both of these are useless in this limited context; you simply want
command
There are some fringe situations where you want the shell to read its configuration file or somehow otherwise set up the environment as a preparation for running command
. This is pretty much the sole situation where exec command
is useful.
#!/bin/sh
ENVIRONMENT=$(some complex task)
exec command
This does some stuff to prepare the environment so that it contains what is needed. Once that's done, the sh
instance is no longer necessary, and so it's a (minor) optimization to simply replace the sh
instance with the command
process, rather than have sh
run it as a child process and wait for it, then exit as soon as it finishes.
Similarly, if you want to free up as much resources as possible for a heavyish command at the end of a shell script, you might want to exec
that command as an optimization.
If something forces you to run sh
but you really wanted to run something else, exec something else
is of course a workaround to replace the undesired sh
instance (like for example if you really wanted to run your own spiffy gosh
instead of sh
but yours isn't listed in /etc/shells
so you can't specify it as your login shell).
The second use of exec
to manipulate file descriptors is a separate topic. The accepted answer covers that nicely; to keep this self-contained, I'll just defer to the manual for anything where exec
is followed by a redirect instead of a command name.
Here's how to do it in Squarespace using the embed block classes to create responsiveness.
Put this into a code block:
<div class="sqs-block embed-block sqs-block-embed" data-block-type="22" >
<div class="sqs-block-content"><div class="intrinsic" style="max-width:100%">
<div class="embed-block-wrapper embed-block-provider-YouTube" style="padding-bottom:56.20609%;">
<iframe allow="autoplay; fullscreen" scrolling="no" data-image-dimensions="854x480" allowfullscreen="true" src="https://www.youtube.com/embed/live_stream?channel=CHANNEL_ID_HERE" width="854" data-embed="true" frameborder="0" title="YouTube embed" class="embedly-embed" height="480">
</iframe>
</div>
</div>
</div>
Tweak however you'd like!
This should work
gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "
Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:
gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')
"Yes yes for ever for ever the boys and the girls"
It looks like you already have a solution. To make things easier, why not just put your command in a bash script (with a short name) and just run that instead of typing out that 'long' command every time?
110
is the Style value for the date format.
Among other answers, I find the easiest way is to use the IDE comment functions which use the Python comment support of #
.
I am using Anaconda Spyder and it has:
It would comment/uncomment a single/multi line/s of code with #
.
I find it the easiest.
For example, a block comment:
# =============================================================================
# Sample Commented code in spyder
# Hello, World!
# =============================================================================
I typically Like to use the GridView.RowDataBound Event event for this.
protected void OrdersGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.ForeColor = System.Drawing.Color.Red;
}
}
Change your code to
<Limit GET POST>
deny from all
allow from 139.82.0.0/16
allow from 143.54.0.0/16
allow from 186.192.0.0/11
allow from 186.224.0.0/11
</Limit>
This way your htaccess will deny every except those that you explicitly allow with allow from..
A proxy within the allow range can easily be overwritten with an additional deny from..
rule.
I see the other one is closed. So basically here's the rough of my code. I think you are missing the string cmd comment. For example if my store procedure is call:DBO.Test. I would need to write cmd="DBO.test". Then do command type equal to store procedure, and blah blah blah
Connection.open();
String cmd="DBO.test"; //the command
Sqlcommand mycommand;
first, make sure you have the language pack installed by doing :
sudo apt-get install language-pack-en-base
sudo dpkg-reconfigure locales
I answered a similar question a while ago. Basically, the best way would be to use the class HttpValueCollection
, which the QueryString
property actually is, unfortunately it is internal in the .NET framework.
You could use Reflector to grab it (and place it into your Utils class). This way you could manipulate the query string like a NameValueCollection, but with all the url encoding/decoding issues taken care for you.
HttpValueCollection
extends NameValueCollection
, and has a constructor that takes an encoded query string (ampersands and question marks included), and it overrides a ToString()
method to later rebuild the query string from the underlying collection.
Although this question is related to string conversion, I stumbled upon this while wanting an easy way to write arrays to my log files. If you just want the info, and don't care about the exact cleanliness of a string you might consider:
json_encode($array)
So if you are on branch release/2.5 and you merge branch feature/new-buttons into it, then the content as found in release/2.5 is what ours refers to and the content as found on feature/new-buttons is what theirs refers to. During a merge action this is pretty straight forward.
The only problem most people fall for is the rebase case. If you do a re-base instead of a normal merge, the roles are swapped. How's that? Well, that's caused solely by the way rebasing works. Think of rebase to work like that:
Of course, that's not really what is going on but it's a nice mind model for me. And if you look at 2 and 3, you will understand why the roles are swapped now. As of 2, your current branch is now the branch from the server without any of your changes, so this is ours (the branch you are on). The changes you made are now on a different branch that is not your current one (BranchX) and thus these changes (despite being the changes you made) are theirs (the other branch used in your action).
That means if you merge and you want your changes to always win, you'd tell git to always choose "ours" but if you rebase and you want all your changes to always win, you tell git to always choose "theirs".
You can call the mklink
provided by cmd
, from PowerShell to make symbolic links:
cmd /c mklink c:\path\to\symlink c:\target\file
You must pass /d
to mklink
if the target is a directory.
cmd /c mklink /d c:\path\to\symlink c:\target\directory
For hard links, I suggest something like Sysinternals Junction.
On Windows7 the .gemrc file is not present, you can let Ruby create one like this (it's not easy to do this in explorer).
gem sources --add http://rubygems.org
You will have to confirm (it's unsafe). Now the file is created in your userprofile folder (c:\users\)
You can edit the textfile to remove the source you added or you can remove it with
gem sources --remove http://rubygems.org
If you have the entire project locally but forgot to add you git ignore and are now tracking some unnecessary files use this command to remove everything
git rm --cached -r .
make sure you are at the root of the project.
Then you can do the usual
git add .
git commit -m 'removed all and added with git ignore'
git push origin master
Hope this helps out people who have to make changes to their .gitignore
or forgot it all together.
I know this is an old post, but changing th or td color is not te right way. I was fooled by this post as well.
First load your bootstrap.css and add this in your own css. This way it is only 2 lines if you have a hovered table, else its only 1 line, unless you want to change odd and even :-)
.table-striped>tbody>tr:nth-child(odd) {
background-color: LemonChiffon;
}
.table-hover tbody tr:hover {
background-color: AliceBlue;
}
