Is it acceptable to answer the original question with a strictly off topic answer:) You can write a formula in the spreadsheet to do this. Ugly perhaps? but effective in the normal operating of a spreadsheet.
=indirect("R"&ArrayFormula(max((G:G<>"")*row(G:G)))&"C"&7)
(G:G<>"") gives an array of true false values representing non-empty/empty cells
(G:G<>"")*row(G:G) gives an array of row numbers with zeros where cell is empty
max((G:G<>"")*row(G:G)) is the last non-empty cell in G
This is offered as a thought for a range of questions in the script area that could be delivered reliably with array formulas which have the advantage of often working in similar fashion in excel and openoffice.
Your code should work just as you expect it to if you add @classmethod
decorators.
@classmethod
def setup_class(cls):
"Runs once per class"
@classmethod
def teardown_class(cls):
"Runs at end of class"

In your MySQL workbench, you can go to the left sidebar, under Management select "Users and Privileges", click root under User Accounts, the in the right section click tab "Account Limits" to increase the max queries, updates, etc, and then click tab "Administrative Roles" and check the boxes to give the account access. Hope that helps!
If you want to use jQuery File Download , please note this for IE. You need to reset the response or it will not download
//The IE will only work if you reset response
getServletResponse().reset();
//The jquery.fileDownload needs a cookie be set
getServletResponse().setHeader("Set-Cookie", "fileDownload=true; path=/");
//Do the reset of your action create InputStream and return
Your action can implement ServletResponseAware
to access getServletResponse()
Continuing from my comment. toString
is not the solution. Some good soul has written whole code for serialization and deserialization of an object in Java. See here: http://www.javabeginner.com/uncategorized/java-serialization
Suggested read:
The problem with using the PasswordBox is that it is not very MVVM friendly due to the fact that it works with SecureString and therefore requires a shim to bind it to a String. You also cannot use the clipboard. While all these things are there for a reason, you may not require that level of security. Here is an alternative approach that works with the clipboard, nothing fancy. You make the TextBox text and background transparent and bind the text to a TextBlock underneath it. This textblock converts characters to * using the converter specified.
<Window.Resources>
<local:TextToPasswordCharConverter x:Key="TextToPasswordCharConverter" />
</Window.Resources>
<Grid Width="200">
<TextBlock Margin="5,0,0,0" Text="{Binding Text, Converter={StaticResource TextToPasswordCharConverter}, UpdateSourceTrigger=PropertyChanged, Mode=OneWay}" FontFamily="Consolas" VerticalAlignment="Center" />
<TextBox Foreground="Transparent" Text="{Binding Text, UpdateSourceTrigger=PropertyChanged}" FontFamily="Consolas" Background="Transparent" />
</Grid>
And here is the Value Converter:
class TextToPasswordCharConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return new String('*', value?.ToString().Length ?? 0);
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
Make sure your Text property on your viewmodel implements INotifyPropertyChanged
There is Q
objects that allow to complex lookups. Example:
from django.db.models import Q
Item.objects.filter(Q(creator=owner) | Q(moderated=False))
If you don't want anything to display before the redirect, then you will need to use some server side scripting to accomplish the task before the page is served. The page has already begun loading by the time your Javascript is executed on the client side.
If Javascript is your only option, your best best is to make your script the first .js file included in the <head>
of your document.
Instead of Javascript, I recommend setting up your redirect logic in your Apache or nginx server configuration.
I had trouble trying to use the WMI method accepted above because i always got privilige not held exceptions despite running the program as an administrator.
The solution was for the process to request the privilege for itself. I found the answer at http://www.dotnet247.com/247reference/msgs/58/292150.aspx written by a guy called Richard Hill.

If you didn't push the update in remote then the simple solution is remove last local commit using following command: git reset HEAD^
. Then add all files and commit again.
Not sure what you meant, but you can permanently turn showing whitespaces on and off in Settings -> Editor -> General -> Appearance -> Show whitespaces
.
Also, you can set it for a current file only in View -> Active Editor -> Show WhiteSpaces
.
Edit:
Had some free time since it looks like a popular issue, I had written a plugin to inspect the code for such abnormalities. It is called Zero Width Characters locator and you're welcome to give it a try.
The fastest way is to do a*a
or a**2
or np.square(a)
whereas np.power(a, 2)
showed to be considerably slower.
np.power()
allows you to use different exponents for each element if instead of 2
you pass another array of exponents. From the comments of @GarethRees I just learned that this function will give you different results than a**2
or a*a
, which become important in cases where you have small tolerances.
I've timed some examples using NumPy 1.9.0 MKL 64 bit, and the results are shown below:
In [29]: a = np.random.random((1000, 1000))
In [30]: timeit a*a
100 loops, best of 3: 2.78 ms per loop
In [31]: timeit a**2
100 loops, best of 3: 2.77 ms per loop
In [32]: timeit np.power(a, 2)
10 loops, best of 3: 71.3 ms per loop
From the jQuery.each() documentation:
.each( function(index, Element) )
function(index, Element)A function to execute for each matched element.
So you'll want to use:
$('#list option').each(function(i,e){
//do stuff
});
...where index will be the index and element will be the option element in list

If it's a UI based application , then " I also need to know what I need to add to my code so that my program waits about 700 milliseconds for a keyinput before moving on to another method" you can use GlassPane or Timer class to fulfill the requirement.
For key Event:
public void keyPressed(KeyEvent e) {
int key = e.getKeyCode();
if (key == KeyEvent.VK_LEFT) {
dx = -1;
}
if (key == KeyEvent.VK_RIGHT) {
dx = 1;
}
if (key == KeyEvent.VK_UP) {
dy = -1;
}
if (key == KeyEvent.VK_DOWN) {
dy = 1;
}
}

like above mention you can use SwiftyJSON library and get your values like i have done below
Alamofire.request(.POST, "MY URL", parameters:parameters, encoding: .JSON) .responseJSON
{
(request, response, data, error) in
var json = JSON(data: data!)
println(json)
println(json["productList"][1])
}
my json product list return from script
{ "productList" :[
{"productName" : "PIZZA","id" : "1","productRate" : "120.00","productDescription" : "PIZZA AT 120Rs","productImage" : "uploads\/pizza.jpeg"},
{"productName" : "BURGER","id" : "2","productRate" : "100.00","productDescription" : "BURGER AT Rs 100","productImage" : "uploads/Burgers.jpg"}
]
}
output :
{
"productName" : "BURGER",
"id" : "2",
"productRate" : "100.00",
"productDescription" : "BURGER AT Rs 100",
"productImage" : "uploads/Burgers.jpg"
}
Generally, The DNS Domain of the URL MUST match the Certificate Subject of the certificate.
In former times this could be either by setting the domain as cn of the certificate or by having the domain set as a Subject Alternative Name.
Support for cn was deprecated for a long time (since 2000 in RFC 2818) and Chrome browser will not even look at the cn anymore so today you need to have the DNS Domain of the URL as a Subject Alternative Name.
RFC 6125 which forbids checking the cn if SAN for DNS Domain is present, but not if SAN for IP Address is present. RFC 6125 also repeats that cn is deprecated which was already said in RFC 2818. And the Certification Authority Browser Forum to be present which in combination with RFC 6125 essentially means that cn will never be checked for DNS Domain name.
Compare every key in mapB against the counterpart in mapA. Then check if there is any key in mapA not existing in mapB
public boolean mapsAreEqual(Map<String, String> mapA, Map<String, String> mapB) {
try{
for (String k : mapB.keySet())
{
if (!mapA.get(k).equals(mapB.get(k))) {
return false;
}
}
for (String y : mapA.keySet())
{
if (!mapB.containsKey(y)) {
return false;
}
}
} catch (NullPointerException np) {
return false;
}
return true;
}
after a lot of tries, I've read in other topics which someone said "delete all your apps and create it again". I did that but, as you can imagine, a new App will create a new Application ID on Facebook's page.
So, even after all the "set public things" it didn't work because the application ID was wrong in my code due to the creation of a new App on Facebook developer page.
So, as AndrewSmiley said above, you should remeber to update that in your app @strings
this should solve your problem.
\cp -rf foo/* bar/
Update The currently suggested way to start a Task is simply using Task.Run()
Task.Run(() => foo());
Note that this method is described as the best way to start a task see here
Previous answer
I like the Task Factory from System.Threading.Tasks. You can do something like this:
Task.Factory.StartNew(() =>
{
// Whatever code you want in your thread
});
Note that the task factory gives you additional convenience options like ContinueWith:
Task.Factory.StartNew(() => {}).ContinueWith((result) =>
{
// Whatever code should be executed after the newly started thread.
});
Also note that a task is a slightly different concept than threads. They nicely fit with the async/await keywords, see here.
I started to get this error when i tried to login to SSMS using 'windows Authentication'. This started to happen after i renamed the Windows SQL server. I tried everything to resolve this error and in my particular case changing the machine names in the 'hosts' file to reflect the name SQL server name change resolved the issue.

0 + $x;
}
catch {

If you're a Tidyverse kind of person, here's the stringr solution:
R> library(stringr)
R> strings = c("TGAS_1121", "MGAS_1432", "ATGAS_1121")
R> strings %>% str_replace(".*_", "_")
[1] "_1121" "_1432" "_1121"
# Or:
R> strings %>% str_replace("^[A-Z]*", "")
[1] "_1121" "_1432" "_1121"
I just stumbled upon a usage of __call__()
in concert with __getattr__()
which I think is beautiful. It allows you to hide multiple levels of a JSON/HTTP/(however_serialized) API inside an object.
The __getattr__()
part takes care of iteratively returning a modified instance of the same class, filling in one more attribute at a time. Then, after all information has been exhausted, __call__()
takes over with whatever arguments you passed in.
Using this model, you can for example make a call like api.v2.volumes.ssd.update(size=20)
, which ends up in a PUT request to https://some.tld/api/v2/volumes/ssd/update
.
The particular code is a block storage driver for a certain volume backend in OpenStack, you can check it out here: https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/nexenta/jsonrpc.py

The correct properties are
server.servlet.path
to configure the path of the DispatcherServlet
and
server.servlet.context-path
to configure the path of the applications context below that.
Strangely you must put the 'font-weight: 900' in some icons so that it shows them.

See http://git.or.cz/gitwiki/GitTips, section "How to compare two local repositories" in "General".
In short you are using GIT_ALTERNATE_OBJECT_DIRECTORIES environment variable to have access to object database of the other repository, and using git rev-parse with --git-dir
/ GIT_DIR to convert symbolic name in other repository to SHA-1 identifier.
Modern version would look something like this (assuming that you are in 'repo_a'):
GIT_ALTERNATE_OBJECT_DIRECTORIES=../repo_b/.git/objects \ git diff $(git --git-dir=../repo_b/.git rev-parse --verify HEAD) HEAD
where ../repo_b/.git
is path to object database in repo_b (it would be repo_b.git if it were bare repository). Of course you can compare arbitrary versions, not only HEADs.
Note that if repo_a and repo_b are the same repository, it might make more sense to put both of them in the same repository, either using "git remote add -f ...
" to create nickname(s) for repository for repeated updates, or obe off "git fetch ...
"; as described in other responses.

For a start the first select has 6 columns and the second has 4 columns. Perhaps make both have the same number of columns (adding nulls?).
First, we choose stable (not static) data columns to form a Primary Key, precisely because updating Keys in a Relational database (in which the references are by Key) is something we wish to avoid.
For this issue, it doesn't matter if the Key is a Relational Key ("made up from the data"), and thus has Relational Integrity, Power, and Speed, or if the "key" is a Record ID, with none of that Relational Integrity, Power, and Speed. The effect is the same.
I state this because there are many posts by the clueless ones, who suggest that this is the exact reason that Record IDs are somehow better than Relational Keys.
The point is, the Key or Record ID is migrated to wherever a reference is required.
Second, if you have to change the value of the Key or Record ID, well, you have to change it. Here is the OLTP Standard-compliant method. Note that the high-end vendors do not allow "cascade update".
Write a proc. Foo_UpdateCascade_tr @ID, where Foo is the table name
Begin a Transaction
First INSERT-SELECT a new row in the parent table, from the old row, with the new Key or RID value
Second, for all child tables, working top to bottom, INSERT-SELECT the new rows, from the old rows, with the new Key or RID value
Third, DELETE the rows in the child tables that have the old Key or RID value, working bottom to top
Last, DELETE the row in the parent table that has the old Key or RID value
Commit the Transaction
The other answers are incorrect.
Disabling constraints and then enabling them, after UPDATing the required rows (parent plus all children) is not something that a person would do in an online production environment, if they wish to remain employed. That advice is good for single-user databases.
The need to change the value of a Key or RID is not indicative of a design flaw. It is an ordinary need. That is mitigated by choosing stable (not static) Keys. It can be mitigated, but it cannot be eliminated.
A surrogate substituting a natural Key, will not make any difference. In the example you have given, the "key" is a surrogate. And it needs to be updated.
There is nothing "tricky" about cascading all the required changes. Refer to the steps given above.
There is nothing that can be prevented re the universe changing. It changes. Deal with it. And since the database is a collection of facts about the universe, when the universe changes, the database will have to change. That is life in the big city, it is not for new players.
People getting married and hedgehogs getting buried are not a problem (despite such examples being used to suggest that it is a problem). Because we do not use Names as Keys. We use small, stable Identifiers, such as are used to Identify the data in the universe.
Don't update the PK! is the second-most hilarious thing I have read in a while. Add a new column is the most.
Try this:
CharSequence[] charArray = {"a","b","c"};
for (int i = 0; i < charArray.length; i++){
String str = charArray.toString().join("", charArray[i]);
System.out.print(str);
}
I've merged some solutions together:
public static int getStatusBarHeight(final Context context) {
final Resources resources = context.getResources();
final int resourceId = resources.getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0)
return resources.getDimensionPixelSize(resourceId);
else
return (int) Math.ceil((VERSION.SDK_INT >= VERSION_CODES.M ? 24 : 25) * resources.getDisplayMetrics().density);
}
another alternative:
final View view = findViewById(android.R.id.content);
runJustBeforeBeingDrawn(view, new Runnable() {
@Override
public void run() {
int statusBarHeight = getResources().getDisplayMetrics().heightPixels - view.getMeasuredHeight();
}
});
EDIT: Alternative to runJustBeforeBeingDrawn: https://stackoverflow.com/a/28136027/878126
I like Rubo77's solution, I hadn't seen it before I modified Paul's. This one will backup a single database, excluding any tables you don't want. It will then gzip it, and delete any files over 8 days old. I will probably use 2 versions of this that do a full (minus logs table) once a day, and another that just backs up the most important tables that change the most every hour using a couple cron jobs.

Just in case you have a preference for how negative numbers are formatted:
p "%x" % -1 #=> "..f"
p -1.to_s(16) #=> "-1"
You should be able to invoke it as python scriptname.py
e.g.
# !/bin/bash
python /home/user/scriptname.py
Also make sure the script has permissions to run.
You can make it executable by using chmod u+x scriptname.py

{ email: payload.email },
{ phoneNumber: payload.phoneNumber }
] })
if (userDB) {
if (payload.email == userDB.email) {
throw new BadRequest({ message: 'E-mail already exists' })
} else if (payload.phoneNumber == userDB.phoneNumber) {
throw new BadRequest({ message: 'phoneNumber already exists' })
}
}
Daniel Kutik's answer is correct, but it can be even more safe, with database renaming.
So, the truly safe way is:
In case of emergency, just rename DBs back
Performance wise both can do equally the same, so the question becomes which saves more development time?
Bash relies on calling other commands, and piping them for creating new ones. This has the advantage that you can quickly create new programs just with the code borrowed from other people, no matter what programming language they used.
This also has the side effect of resisting change in sub-commands pretty well, as the interface between them is just plain text.
Additionally Bash is very permissive on how you can write on it. This means it will work well for a wider variety of context, but it also relies on the programmer having the intention of coding in a clean safe manner. Otherwise Bash won't stop you from building a mess.
Python is more structured on style, so a messy programmer won't be as messy. It will also work on operating systems outside Linux, making it instantly more appropriate if you need that kind of portability.
But it isn't as simple for calling other commands. So if your operating system is Unix most likely you will find that developing on Bash is the fastest way to develop.
When to use Bash:
When to use Python:
Multiple inheritance is not supported in C#.
But if you want to "inherit" behavior from two sources why not use the combination of:
There is a basic but important OOP principle that says: "Favor composition over inheritance".
You can create a class like this:
public class MySuperClass
{
private IDependencyClass1 mDependency1;
private IDependencyClass2 mDependency2;
public MySuperClass(IDependencyClass1 dep1, IDependencyClass2 dep2)
{
mDependency1 = dep1;
mDependency2 = dep2;
}
private void MySuperMethodThatDoesSomethingComplex()
{
string s = mDependency1.GetMessage();
mDependency2.PrintMessage(s);
}
}
As you can see the dependecies (actual implementations of the interfaces) are injected via the constructor. You class does not know how each class is implemented but it knows how to use them. Hence, a loose coupling between the classes involved here but the same power of usage.
Today's trends show that inheritance is kind of "out of fashion".
You may use something like this to call the handler written on click:
import { shallow } from 'enzyme'; // Mount is not required
page = <MyCoolPage />;
pageMounted = shallow(page);
// The below line will execute your click function
pageMounted.instance().yourOnClickFunction();
You need to specify workseet. Change line
If Worksheet.Cells(i, 1).Value = "X" Then
to
If Worksheets("Sheet2").Cells(i, 1).Value = "X" Then
UPD:
Try to use following code (but it's not the best approach. As @SiddharthRout suggested, consider about using Autofilter):
Sub LastRowInOneColumn()
Dim LastRow As Long
Dim i As Long, j As Long
'Find the last used row in a Column: column A in this example
With Worksheets("Sheet2")
LastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
End With
MsgBox (LastRow)
'first row number where you need to paste values in Sheet1'
With Worksheets("Sheet1")
j = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
End With
For i = 1 To LastRow
With Worksheets("Sheet2")
If .Cells(i, 1).Value = "X" Then
.Rows(i).Copy Destination:=Worksheets("Sheet1").Range("A" & j)
j = j + 1
End If
End With
Next i
End Sub
Change [
to [[
, and ]
to ]]
.
In order to select an element by attribute having a specific characteristic you may create a new selector like in the following snippet using a regex pattern. The usage of regex is intended to make flexible the new selector as much as possible:
jQuery.extend(jQuery.expr[':'], {
nameMatch: function (ele, idx, selector) {
var rpStr = (selector[3] || '').replace(/^\/(.*)\/$/, '$1');
return (new RegExp(rpStr)).test(ele.name);
}
});
//
// use of selector
//
$('input:nameMatch(/^pages_title\\[\\d\\]$/)').each(function(idx, ele) {
console.log(ele.outerHTML);
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" value="2" name="pages_title[1]">
<input type="text" value="1" name="pages_title[2]">
<input type="text" value="1" name="pages_title[]">
_x000D_
Another solution can be based on:
[name^=”value”]: selects elements that have the specified attribute with a value beginning exactly with a given string.
.filter(): reduce the set of matched elements to those that match the selector or pass the function's test.
var selectedEle = $(':input[name^="pages_title"]').filter(function(idx, ele) {
//
// test if the name attribute matches the pattern.....
//
return /^pages_title\[\d\]$/.test(ele.name);
});
selectedEle.each(function(idx, ele) {
console.log(ele.outerHTML);
});
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" value="2" name="pages_title[1]">

For perl,
To run perl script use this procedure
Requirement: You need to setup classpath variable.
Go to plugins->NppExec->Execute
In command section, type this
cmd /c cd "$(CURRENT_DIRECTORY)"&&"$(FULL_CURRENT_PATH)"
Save it and give name to it.(I give Perl).
Press OK. If editor wants to restart, do it first.
Now press F6 and you will find your Perl script output on below side.
Note: Not required seperate config for seperate files.
For java,
Requirement: You need to setup JAVA_HOME
and classpath
variable.
Go to plugins->NppExec->Execute
In command section, type this
cmd /c cd "$(CURRENT_DIRECTORY)"&&"%JAVA_HOME%\bin\javac""$(FULL_CURRENT_PATH)"
your *.class
will generate on location of current folder; despite of programming error.
For Python,
Use this Plugin Python Plugin
Go to plugins->NppExec-> Run file in Python intercative
By using this you can run scripts within Notepad++.
For PHP,
No need for different configuration just download this plugin.
PHP Plugin and done.
For C language,
Requirement: You need to setup classpath variable.
I am using MinGW compiler.
Go to plugins->NppExec->Execute
paste this into there
NPP_SAVE
CD $(CURRENT_DIRECTORY)
C:\MinGW32\bin\gcc.exe -g "$(FILE_NAME)"
a
(Remember to give above four lines separate lines.)
Now, give name, save and ok.
Restart Npp.
Go to plugins->NppExec->Advanced options.
Menu Item->Item Name (I have C compiler)
Associated Script-> from combo box select the above name of script.
Click on Add/modify and Ok.
Now assign shortcut key as given in first answer.
Press F6 and select script or just press shortcut(I assigned Ctrl+2).
For C++,
Only change g++ instead of gcc
and *.cpp
instead on *.c
That's it!!
How about that?
function internalHandler(e) {
e.preventDefault(); // required in some browsers
e.returnValue = ""; // required in some browsers
return "Custom message to show to the user"; // only works in old browsers
}
if (window.addEventListener) {
window.addEventListener('beforeunload', internalHandler, true);
} else if (window.attachEvent) {
window.attachEvent('onbeforeunload', internalHandler);
}
Never do a git -f
to do push
as it can result in later disastrous consequences.
You just need to do a git pull
of your local branch.
Ex:
git pull origin 'your_local_branch'
and then do a git push
As other guys commented before you can write your own procedure with anonymous function to solve this issue.
I used two ways to solve it:
func Find(slice interface{}, f func(value interface{}) bool) int {
s := reflect.ValueOf(slice)
if s.Kind() == reflect.Slice {
for index := 0; index < s.Len(); index++ {
if f(s.Index(index).Interface()) {
return index
}
}
}
return -1
}
Uses example:
type UserInfo struct {
UserId int
}
func main() {
var (
destinationList []UserInfo
userId int = 123
)
destinationList = append(destinationList, UserInfo {
UserId : 23,
})
destinationList = append(destinationList, UserInfo {
UserId : 12,
})
idx := Find(destinationList, func(value interface{}) bool {
return value.(UserInfo).UserId == userId
})
if idx < 0 {
fmt.Println("not found")
} else {
fmt.Println(idx)
}
}
Second method with less computational cost:
func Search(length int, f func(index int) bool) int {
for index := 0; index < length; index++ {
if f(index) {
return index
}
}
return -1
}
Uses example:
type UserInfo struct {
UserId int
}
func main() {
var (
destinationList []UserInfo
userId int = 123
)
destinationList = append(destinationList, UserInfo {
UserId : 23,
})
destinationList = append(destinationList, UserInfo {
UserId : 123,
})
idx := Search(len(destinationList), func(index int) bool {
return destinationList[index].UserId == userId
})
if idx < 0 {
fmt.Println("not found")
} else {
fmt.Println(idx)
}
}
None of these solutions worked for me. But I was able to get vertical centering by using <div class="form-row align-items-center">
for each form row, per the Bootstrap examples.
spinner.setSelection(Adapter.NO_SELECTION, false);
I ran into this same issue, but I think I know what's causing the confusion. If you use MySql Query Analyzer, you can do this just fine:
SELECT myvalue
INTO @myvar
FROM mytable
WHERE anothervalue = 1;
However, if you put that same query in MySql Workbench, it will throw a syntax error. I don't know why they would be different, but they are. To work around the problem in MySql Workbench, you can rewrite the query like this:
SELECT @myvar:=myvalue
FROM mytable
WHERE anothervalue = 1;
Made an improvement code by @Ipsita - for use asynchronous read\write file I/O
readonly string logPath = @"FilePath";
...
public async Task WriteToLogAsync(string dataToWrite)
{
TextReader tr = new StreamReader(logPath);
string data = await tr.ReadLineAsync();
tr.Close();
TextWriter tw = new StreamWriter(logPath);
await tw.WriteLineAsync(data + dataToWrite);
tw.Close();
}
...
await WriteToLogAsync("Write this to file");
SELECT OTHER_COLUMNS FROM posted WHERE link in (
SELECT DISTINCT link FROM posted WHERE ad='$key' )
ORDER BY day, month
This is my aproximation:
Declare
Variableclob Clob;
Temp_Save Varchar2(32767); //whether it is greater than 4000
Begin
Select reportClob Into Temp_Save From Reporte Where Id=...;
Variableclob:=To_Clob(Temp_Save);
Dbms_Output.Put_Line(Variableclob);
End;
I used Custom Action separately coded in C++ DLL and used the DLL to call appropriate function on Uninstalling using this syntax :
<CustomAction Id="Uninstall" BinaryKey="Dll_Name"
DllEntry="Function_Name" Execute="deferred" />
Using the above code block, I was able to run any function defined in C++ DLL on uninstall. FYI, my uninstall function had code regarding Clearing current user data and registry entries.

Microsoft is moving away from software and database diagramming using Visio and instead transitioning into Visual Studio. See the "Modeling" Projects. Component Diagrams, Sequence Diagrams, Use Cases, Layer Diagrams are all part of the modeling project. While I am experimenting with it (but question its viability), you can generate code from the models creating in the code generation sense.

Here's what I have available in vs2013 ultimate
This works on Windows with Cygwin installed:
System.getenv("NUMBER_OF_PROCESSORS")
I would suggest
sapply(foo, typeof)
if you need the actual types of the vectors in the data frame. class()
is somewhat of a different beast.
If you don't need to get this information as a vector (i.e. you don't need it to do something else programmatically later), just use str(foo)
.
In both cases foo
would be replaced with the name of your data frame.
For anyone else stuck with this, it's probably not working because the ajax call is interpreting your returned data as text - i.e. it's not yet a JSON object.
You can convert it to a JSON object by manually using the parseJSON command or simply adding the dataType: 'json' property to your ajax call. e.g.
jQuery.ajax({
type: 'POST',
url: '<?php echo admin_url('admin-ajax.php'); ?>',
data: data,
dataType: 'json', // ** ensure you add this line **
success: function(data) {
jQuery.each(data, function(index, item) {
//now you can access properties using dot notation
});
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert("some error");
}
});
If you want to allow 1
and 1.2
:
(?<=^| )\d+(\.\d+)?(?=$| )
If you want to allow 1
, 1.2
and .1
:
(?<=^| )\d+(\.\d+)?(?=$| )|(?<=^| )\.\d+(?=$| )
If you want to only allow 1.2
(only floats):
(?<=^| )\d+\.\d+(?=$| )
\d
allows digits (while \D
allows anything but digits).
(?<=^| )
checks that the number is preceded by either a space or the beginning of the string. (?=$| )
makes sure the string is followed by a space or the end of the string. This makes sure the number isn't part of another number or in the middle of words or anything.
Edit: added more options, improved the regexes by adding lookahead- and behinds for making sure the numbers are standalone (i.e. aren't in the middle of words or other numbers.
How it works: It is a variable that can store another pointer.
When would you use them : Many uses one of them is if your function wants to construct an array and return it to the caller.
//returns the array of roll nos {11, 12} through paramater
// return value is total number of students
int fun( int **i )
{
int *j;
*i = (int*)malloc ( 2*sizeof(int) );
**i = 11; // e.g., newly allocated memory 0x2000 store 11
j = *i;
j++;
*j = 12; ; // e.g., newly allocated memory 0x2004 store 12
return 2;
}
int main()
{
int *i;
int n = fun( &i ); // hey I don't know how many students are in your class please send all of their roll numbers.
for ( int j=0; j<n; j++ )
printf( "roll no = %d \n", i[j] );
return 0;
}
Be careful with the slash, change "\" for "/" , like this: adb.exe push SuperSU-v2.79-20161205182033.apk /storage
You need to make sure images come first and put in a comma after the background image call. then it actually does work:

background:url(egg.png) no-repeat 70px 2px, linear-gradient(top, #82d4fe 0%,#1db2ff 78%); /* W3C */
I had the same problem. I was able to solve the problem from application side, under the following scenario:
JDK8, spring framework 4.2.4.RELEASE, apache tomcat 7.0.63, Oracle Database 11g Enterprise Edition 11.2.0.4.0
I used the database connection pooling apache tomcat-jdbc

A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.
The Runnable Interface requires of the class to implement the method run()
like so:
public class MyRunnableTask implements Runnable {
public void run() {
// do stuff here
}
}
And then use it like this:
Thread t = new Thread(new MyRunnableTask());
t.start();
If you did not have the Runnable
interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run()
method in your class, so you could get errors. That is why you need to implement the interface.
Note that you do not need to define a class as usual, you can do all of that inline:
Thread t = new Thread(new Runnable() {
public void run() {
// stuff here
}
});
t.start();
This is similar to the above, only you don't create another named class.
What parsers and lexers have in common:
*
, ==
, <=
, ^
will be classified as "operator" token by the C/C++ lexer.[number][operator][number]
, [id][operator][id]
, [id][operator][number][operator][number]
will be classified as "expression" nonterminal by the C/C++ parser.[TXT][TAG][TAG][TXT][TAG][TXT]...
.As you can see, parsers and tokenizers have much in common. One parser can be a tokenizer for other parser, which reads its input tokens as symbols from its own alphabet (tokens are simply symbols of some alphabet) in the same way as sentences from one language can be alphabetic symbols of some other, higher-level language. For example, if *
and -
are the symbols of the alphabet M
(as "Morse code symbols"), then you can build a parser which recognizes strings of these dots and lines as letters encoded in the Morse code. The sentences in the language "Morse Code" could be tokens for some other parser, for which these tokens are atomic symbols of its language (e.g. "English Words" language). And these "English Words" could be tokens (symbols of the alphabet) for some higher-level parser which understands "English Sentences" language. And all these languages differ only in the complexity of the grammar. Nothing more.
So what's all about these "Chomsky's grammar levels"? Well, Noam Chomsky classified grammars into four levels depending on their complexity:
a
,b
), their concatenations (ab
,aba
,bbb
etd.), or alternatives (e.g. a|b
).(()()(()()))
, nested HTML/BBcode tags, nested blocks etc. It's because state automata to deal with it should have to have infinitely many states to handle infinitely many nesting levels.x+3
and in one context this x
could be a name of a variable, and in other context it could be a name of a function etc.EDIT After some hunting around, this seems to be the best option:

You can see a customised version of this InfoBubble that I used on Dive Seven, a website for online scuba dive logging. It looks like this:
There are some more examples here. They definitely don't look as nice as the example in your screenshot, however.
If you have only these regular shapes, there is a simple procedure as follows :
approxPolyDP
function.Below is my example in Python:
import numpy as np
import cv2
img = cv2.imread('shapes.png')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
ret,thresh = cv2.threshold(gray,127,255,1)
contours,h = cv2.findContours(thresh,1,2)
for cnt in contours:
approx = cv2.approxPolyDP(cnt,0.01*cv2.arcLength(cnt,True),True)
print len(approx)
if len(approx)==5:
print "pentagon"
cv2.drawContours(img,[cnt],0,255,-1)
elif len(approx)==3:
print "triangle"
cv2.drawContours(img,[cnt],0,(0,255,0),-1)
elif len(approx)==4:
print "square"
cv2.drawContours(img,[cnt],0,(0,0,255),-1)
elif len(approx) == 9:
print "half-circle"
cv2.drawContours(img,[cnt],0,(255,255,0),-1)
elif len(approx) > 15:
print "circle"
cv2.drawContours(img,[cnt],0,(0,255,255),-1)
cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()
Below is the output:
Remember, it works only for regular shapes.

The situation you describe is pretty fishy. Whenever you close your program's startup form, the entire application should quit automatically, including closing all other open forms. Make sure that you're closing the correct form, and you should not experience any problems.
The other possibility is that you've changed your project (using its Properties page) not to close until all open windows have been closed. In this mode, your application will not exit until the last remaining open form has been closed. If you've chosen this setting, you have to make sure that you call the Close
method of all forms that you've shown during the course of application, not just the startup/main form.
The first setting is the default for a reason, and if you've changed it, you probably want to go fix it back.
It is by far the most intuitive model for normal applications, and it prevents exactly the situation you describe. For it to work properly, make sure that you have specified your main form as the "Startup form" (rather than a splash screen or log-in form).
The settings I'm talking about are highlighted here:
But primarily, note that you should never have to call Application.Exit
in a properly-designed application. If you find yourself having to do this in order for your program to close completely, then you are doing something wrong. Doing it is not a bad practice in itself, as long as you have a good reason. The other two answers fail to explain that, and thus I feel are incomplete at best.

A lambda solution for current python 3.x versions:
d1 = dict(alice='apples', bob='bananas')
d2 = dict(map(lambda key: (d1[key], key), d1.keys()))
print(d2)
Result:
{'apples': 'alice', 'bananas': 'bob'}
This solution does not check for duplicates.
Some remarks:
for
loop. It also avoids using a list comprehension
for those who are bad at math ;-)If you only got one IP on the server, there is no chance to do that. DNS is a simple name to number (IP) resolver. If you have two IPs on the server, you can point each subdomain to each of the IP-addresses and run both servers on the default port on each IP.
one.example.com -> 127.0.0.1 (server: 127.0.0.1:25565)
two.example.com -> 127.0.0.2 (server: 127.0.0.2:25565)
Looks like you are hitting the limit on connections per server. I see you are loading a lot of static files and my advice is to separate them on subdomains and serve them directly with Nginx for example.
Create a subdomain called img.yoursite.com and load all your images from there.
Create a subdomain called scripts.yourdomain.com and load all your JS and CSS files from there.
Create a subdomain called sounds.yoursite.com and load all your MP3s from there... etc..
Nginx has great options for directly serving static files and managing the static files caching.
You can use a tool called: NETSH
To view your system proxy information via command line:
netsh.exe winhttp show proxy
Another way to view it is to open IE, then click on the "gear" icon, then Internet options -> Connections tab -> click on LAN settings
Use fmod()
from <cmath>
. If you do not want to include the C header file:
template<typename T, typename U>
constexpr double dmod (T x, U mod)
{
return !mod ? x : x - mod * static_cast<long long>(x / mod);
}
//Usage:
double z = dmod<double, unsigned int>(14.3, 4);
double z = dmod<long, float>(14, 4.6);
//This also works:
double z = dmod(14.7, 0.3);
double z = dmod(14.7, 0);
double z = dmod(0, 0.3f);
double z = dmod(myFirstVariable, someOtherVariable);
Improvement to kaiser's answer:
var myEl = $document.find('#some-id');
Don't forget to inject $document
into your directive
If copy assignment operator of foo and bar is cheap (eg. int, char, pointer etc), you can do the following:
foo f; bar b;
BOOST_FOREACH(boost::tie(f,b),testing)
{
cout << "Foo is " << f << " Bar is " << b;
}
Use execfile for Python 2:
>>> execfile('C:\\test.py')
Use exec for Python 3
>>> exec(open("C:\\test.py").read())
This isn't exactly the answer, but it's a solution that is similar. It may help people who were in the same boat as I was.
My image, an application logo, had a transparent background, and I was applying an XML gradient as the image background. I added the necessary padding/margins to the imageView in XML, then added this as my background:
<?xml version="1.0" encoding="utf-8"?>
<item>
<shape>
<gradient
android:type="linear"
android:startColor="@color/app_color_light_background"
android:endColor="@color/app_color_disabled"

/>
<!-- Round the top corners. -->
<corners
android:topLeftRadius="@dimen/radius_small"
android:topRightRadius="@dimen/radius_small"
/>
</shape>
</item>
Let me expand a bit on a VonC's very comprehensive answer:
First, if I remember it correctly, the fact that Git by default doesn't create merge commits in the fast-forward case has come from considering single-branch "equal repositories", where mutual pull is used to sync those two repositories (a workflow you can find as first example in most user's documentation, including "The Git User's Manual" and "Version Control by Example"). In this case you don't use pull to merge fully realized branch, you use it to keep up with other work. You don't want to have ephemeral and unimportant fact when you happen to do a sync saved and stored in repository, saved for the future.
Note that usefulness of feature branches and of having multiple branches in single repository came only later, with more widespread usage of VCS with good merging support, and with trying various merge-based workflows. That is why for example Mercurial originally supported only one branch per repository (plus anonymous tips for tracking remote branches), as seen in older revisions of "Mercurial: The Definitive Guide".
Second, when following best practices of using feature branches, namely that feature branches should all start from stable version (usually from last release), to be able to cherry-pick and select which features to include by selecting which feature branches to merge, you are usually not in fast-forward situation... which makes this issue moot. You need to worry about creating a true merge and not fast-forward when merging a very first branch (assuming that you don't put single-commit changes directly on 'master'); all other later merges are of course in non fast-forward situation.

Since java 7 you can the java.nio package to achieve the same result:
Path dir = ...;

try (DirectoryStream<Path> stream = Files.newDirectoryStream(dir, "*.{java,class,jar}")) {
for (Path entry: stream) {
files.add(entry.toFile());
}
return files;

You can display flex items inline, providing your assumption is based on wanting flexible inline items in the 1st place. Using flex implies a flexible block level element.
The simplest approach is to use a flex container with its children set to a flex property. In terms of code this looks like this:
.parent{
display: inline-flex;
}
.children{
flex: 1;
}
flex: 1
denotes a ratio, similar to percentages of a element's width.
Check these two links in order to see simple live Flexbox examples:
If you use the 1st example:
https://njbenjamin.com/flex/index_1.htm
You can play around with your browser console, to change the display
of the container element between flex
and inline-flex

Controller as version (recommended)
Here the template
<div ng-app="example" ng-controller="myController as $ctrl">
<input type="text" ng-model="$ctrl.searchText" />
<button ng-click="$ctrl.check()">Check!</button>
{{ $ctrl.searchText }}
</div>
The JS
angular.module('example', [])
.controller('myController', function() {
var vm = this;
vm.check = function () {
console.log(vm.searchText);
};
});
An example: http://codepen.io/Damax/pen/rjawoO
The best will be to use component with Angular 2.x or Angular 1.5 or upper
########Old way (NOT recommended)
This is NOT recommended because a string is a primitive, highly recommended to use an object instead
Try this in your markup
<input type="text" ng-model="searchText" />
<button ng-click="check(searchText)">Check!</button>
{{ searchText }}
and this in your controller
$scope.check = function (searchText) {
console.log(searchText);
}
I was in a situation where Linq binding was not available and had to expand lambda explicitly. It resulted in a simple function:
public static T KeyByValue<T, W>(this Dictionary<T, W> dict, W val)
{
T key = default;
foreach (KeyValuePair<T, W> pair in dict)
{
if (EqualityComparer<W>.Default.Equals(pair.Value, val))
{
key = pair.Key;
break;
}
}
return key;
}
Call it like follows:
public static void Main()
{
Dictionary<string, string> dict = new Dictionary<string, string>()
{
{"1", "one"},
{"2", "two"},
{"3", "three"}
};
string key = KeyByValue(dict, "two");
Console.WriteLine("Key: " + key);
}

int main()
{
struct student s1;
char myname[30] = "John";
strcpy_s (s1.name, strlen(myname) + 1 ,myname );
s1.age = 21;
cout << " Name: " << s1.name << " age: " << s1.age << endl;
return 0;

Actually you're close to your goal, you just need to use nodes() method to split your rows and then get values:
select
s.SqmId,
m.c.value('@id', 'varchar(max)') as id,
m.c.value('@type', 'varchar(max)') as type,
m.c.value('@unit', 'varchar(max)') as unit,
m.c.value('@sum', 'varchar(max)') as [sum],
m.c.value('@count', 'varchar(max)') as [count],
m.c.value('@minValue', 'varchar(max)') as minValue,
m.c.value('@maxValue', 'varchar(max)') as maxValue,
m.c.value('.', 'nvarchar(max)') as Value,
m.c.value('(text())[1]', 'nvarchar(max)') as Value2
from sqm as s
outer apply s.data.nodes('Sqm/Metrics/Metric') as m(c)
Check out pyftpdlib from Giampaolo Rodola. It is one of the very best ftp servers out there for python. It's used in google's chromium (their browser) and bazaar (a version control system). It is the most complete implementation on Python for RFC-959 (aka: FTP server implementation spec).
To install:
pip3 install pyftpdlib
From the commandline:
python3 -m pyftpdlib
Alternatively 'my_server.py':
#!/usr/bin/env python3
from pyftpdlib import servers
from pyftpdlib.handlers import FTPHandler
address = ("0.0.0.0", 21) # listen on every IP on my machine on port 21
server = servers.FTPServer(address, FTPHandler)
server.serve_forever()
There's more examples on the website if you want something more complicated.
To get a list of command line options:
python3 -m pyftpdlib --help
Note, if you want to override or use a standard ftp port, you'll need admin privileges (e.g. sudo).

Have puzzled over this whilst developing a quick prototype web app under iOS4.2 (dev build). Solution is actually quite simple. Note that you can't seem to already have the tag in your HTML page, you actually need to insert the tag into the document dynamically (note this example uses Prototype 1.7 for some extra Javascript snazziness):
this.soundFile = new Element("audio", {id: "audio-1", src: "audio-1.mp3", controls: ""});
document.body.appendChild(this.soundFile);
this.soundFile.load();
this.soundFile.play();
As you've not set a controller, there shouldn't be any need to do anything tricksy with CSS to hide it / position it off-screen.
This seems to work perfectly.
Quick answer:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
Boolean Music;
public static final String PREFS_NAME = "MyPrefsFile";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//restore preferences
SharedPreferences settings = this.getSharedPreferences(PREFS_NAME, 0);
Music = settings.getBoolean("key", true);
}
@Override
public void onClick() {
//save music setup to system
SharedPreferences settings = this.getSharedPreferences(PREFS_NAME, 0);
SharedPreferences.Editor editor = settings.edit();
editor.putBoolean("key", Music);
editor.apply();
}
}
In case if you need create text file based on one single string:
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
public class StringWriteSample {
public static void main(String[] args) {
String text = "This is text to be saved in file";
try {
Files.write(Paths.get("my-file.txt"), text.getBytes());
} catch (IOException e) {
e.printStackTrace();
}
}
}
For latest Swift Version:
Create a file, name it UIWindowExtension.swift
and paste the following snippet:
import UIKit
public extension UIWindow {
public var visibleViewController: UIViewController? {
return UIWindow.getVisibleViewControllerFrom(self.rootViewController)
}
public static func getVisibleViewControllerFrom(vc: UIViewController?) -> UIViewController? {
if let nc = vc as? UINavigationController {
return UIWindow.getVisibleViewControllerFrom(nc.visibleViewController)
} else if let tc = vc as? UITabBarController {
return UIWindow.getVisibleViewControllerFrom(tc.selectedViewController)
} else {
if let pvc = vc?.presentedViewController {
return UIWindow.getVisibleViewControllerFrom(pvc)
} else {
return vc
}
}
}
}
func getTopViewController() -> UIViewController? {
let appDelegate = UIApplication.sharedApplication().delegate
if let window = appDelegate!.window {
return window?.visibleViewController
}
return nil
}
Use it anywhere as:
if let topVC = getTopViewController() {
}
<select name="aa" onchange="report(this.value)">
<option value="">Please select</option>
<option value="daily">daily</option>
<option value="monthly">monthly</option>
</select>
using
function report(period) {
if (period=="") return; // please select - possibly you want something else here
const report = "script/"+((period == "daily")?"d":"m")+"_report.php";
loadXMLDoc(report,'responseTag');
document.getElementById('responseTag').style.visibility='visible';
document.getElementById('list_report').style.visibility='hidden';
document.getElementById('formTag').style.visibility='hidden';
}
Unobtrusive version:
<select id="aa" name="aa">
<option value="">Please select</option>
<option value="daily">daily</option>
<option value="monthly">monthly</option>
</select>
using
window.addEventListener("load",function() {
document.getElementById("aa").addEventListener("change",function() {
const period = this.value;
if (period=="") return; // please select - possibly you want something else here
const report = "script/"+((period == "daily")?"d":"m")+"_report.php";
loadXMLDoc(report,'responseTag');
document.getElementById('responseTag').style.visibility='visible';
document.getElementById('list_report').style.visibility='hidden';
document.getElementById('formTag').style.visibility='hidden';
});
});
jQuery version - same select with ID
$(function() {
$("#aa").on("change",function() {
const period = this.value;
if (period=="") return; // please select - possibly you want something else here
var report = "script/"+((period == "daily")?"d":"m")+"_report.php";
loadXMLDoc(report,'responseTag');
$('#responseTag').show();
$('#list_report').hide();
$('#formTag').hide();
});
});
Simply outputting something is PowerShell is a thing of beauty - and one its greatest strengths. For example, the common Hello, World! application is reduced to a single line:
"Hello, World!"
It creates a string object, assigns the aforementioned value, and being the last item on the command pipeline it calls the .toString()
method and outputs the result to STDOUT
(by default). A thing of beauty.
The other Write-*
commands are specific to outputting the text to their associated streams, and have their place as such.
For python you could use openpyxl for all 2010 and newer file formats (xlsx).
Al Sweigart has a full tutorial from automate the boring parts on working with excel spreadsheets its very indepth and the whole book and accompanying Udemy course are great resources.
From his example
>>> import openpyxl
>>> wb = openpyxl.load_workbook('example.xlsx')
>>> wb.get_sheet_names()
['Sheet1', 'Sheet2', 'Sheet3']
>>> sheet = wb.get_sheet_by_name('Sheet3')
>>> sheet
<Worksheet "Sheet3">
Understandably once you have this access you can now use psycopg to parse the data to postgres as you normally would do.
This is a link to a list of python resources at python-excel also xlwings provides a large array of features for using python in place of vba in excel.
Writing the actual condition can be the tricky part, so I tend to
Advantages of using the Immediate window:
This example breaks when the code is referring to a table with the name "Setting":
table.GetTableName().Contains("Setting")
Here is another way...
It adds "others" to the enum definition of the column "rtipo" of the table "firmas".
set @new_enum = 'others';
set @table_name = 'firmas';
set @column_name = 'rtipo';
select column_type into @tmp from information_schema.columns
where table_name = @table_name and column_name=@column_name;
set @tmp = insert(@tmp, instr(@tmp,')'), 0, concat(',\'', @new_enum, '\'') );
set @tmp = concat('alter table ', @table_name, ' modify ', @column_name, ' ', @tmp);
prepare stmt from @tmp;
execute stmt;
deallocate prepare stmt;
where returns ActiveRecord::Relation
Now take a look at find_by implementation:
def find_by
where(*args).take
end
As you can see find_by is the same as where but it returns only one record. This method should be used for getting 1 record and where should be used for getting all records with some conditions.
You should target the smallest, not the largest, supported pixel resolution by the devices your app can run on.
Say if there's an actual Mac computer that can run OS X 10.9 and has a native screen resolution of only 1280x720 then that's the resolution you should focus on. Any higher and your game won't correctly run on this device and you could as well remove that device from your supported devices list.
You can rely on upscaling to match larger screen sizes, but you can't rely on downscaling to preserve possibly important image details such as text or smaller game objects.
The next most important step is to pick a fitting aspect ratio, be it 4:3 or 16:9 or 16:10, that ideally is the native aspect ratio on most of the supported devices. Make sure your game only scales to fit on devices with a different aspect ratio.
You could scale to fill but then you must ensure that on all devices the cropped areas will not negatively impact gameplay or the use of the app in general (ie text or buttons outside the visible screen area). This will be harder to test as you'd actually have to have one of those devices or create a custom build that crops the view accordingly.
Alternatively you can design multiple versions of your game for specific and very common screen resolutions to provide the best game experience from 13" through 27" displays. Optimized designs for iMac (desktop) and a Macbook (notebook) devices make the most sense, it'll be harder to justify making optimized versions for 13" and 15" plus 21" and 27" screens.
But of course this depends a lot on the game. For example a tile-based world game could simply provide a larger viewing area onto the world on larger screen resolutions rather than scaling the view up. Provided that this does not alter gameplay, like giving the player an unfair advantage (specifically in multiplayer).
You should provide @2x images for the Retina Macbook Pro and future Retina Macs.
Sounds like you want a mirror of the remote repository:
git clone --mirror url://to/remote.git local.git

In .net2.0 you can use the variable Application.UserAppDataPath
Text inputs do not fire the change
event until they lose focus. Click outside of the input and the alert will show.
If the callback should fire before the text input loses focus, use the .keyup()
event.
If you want a variable to be accessible across the entire page, it works well to define it at the top of the file. (You can use either an implicit or explicit type.)

Your problem comes from the 32/64 bit version of your JDK/JRE... Your shared lib is searched for a 32 bit version.
Your default JDK is a 32 bit version. Try to install a 64 bit one by default and relaunch your `.sh file.
Optional
api provides methods for getting the values. You can check isPresent()
for the presence of the value and then make a call to get()
or you can make a call to get()
chained with orElse()
and provide a default value.
The last thing you can try doing is using @Query()
over a custom method.
Check your remote with git remote -v Something like ssh:///gituser@myhost:/git/dev.git
is wrong because of the triple /// slash
Remove the \s
from your new regex and it should work - whitespace is already included in "anything but alphanumerics".
Note that you may want to add a +
after the ]
so you don't get sequences of more than one underscore. You can also chain onto .replace(/^_+|_+$/g,'')
to trim off underscores at the start or end of the string.
For completely silencing the output, here what works for me

error = FALSE
warning = FALSE

Below is how I got this working.
The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.
[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]
[HttpPost]
public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)
{
var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
}
The JQuery script used to call this action method:
var requestData = {
InvoiceNumber: $.trim(this.value),
SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
};
$.ajax({
url: '/en/myController/GetDataForInvoiceNumber',
type: 'POST',
data: JSON.stringify(requestData),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
error: function (xhr) {
alert('Error: ' + xhr.statusText);
},
success: function (result) {
CheckIfInvoiceFound(result);
},
async: true,
processData: false
});
Simple, correct, solution - define the background image and colour in html, not body. Unless you've defined a specific height (not a percentage) in the body, its height will be assumed to be as tall as required to hold all content. so your background styling should go into html, which is the entire html document, not just the body. Simples.
I think you are looking for the Dictionary object, found in the Microsoft Scripting Runtime library. (Add a reference to your project from the Tools...References menu in the VBE.)
It pretty much works with any simple value that can fit in a variant (Keys can't be arrays, and trying to make them objects doesn't make much sense. See comment from @Nile below.):
Dim d As dictionary
Set d = New dictionary
d("x") = 42
d(42) = "forty-two"
d(CVErr(xlErrValue)) = "Excel #VALUE!"
Set d(101) = New Collection
You can also use the VBA Collection object if your needs are simpler and you just want string keys.
I don't know if either actually hashes on anything, so you might want to dig further if you need hashtable-like performance. (EDIT: Scripting.Dictionary does use a hash table internally.)
The ugly workaround would be to pass a boolean param to Papa indicating that you do not wish to parse the code contained in it's constructor. i.e:
// main class that everything inherits
class Grandpa
{
public function __construct()
{
}
}
class Papa extends Grandpa
{
public function __construct($bypass = false)
{
// only perform actions inside if not bypassing
if (!$bypass) {
}
// call Grandpa's constructor
parent::__construct();
}
}
class Kiddo extends Papa
{
public function __construct()
{
$bypassPapa = true;
parent::__construct($bypassPapa);
}
}
Think about somebody doing help(yourmodule)
at the interactive interpreter's prompt — what do they want to know? (Other methods of extracting and displaying the information are roughly equivalent to help
in terms of amount of information). So if you have in x.py
:
"""This module does blah blah."""
class Blah(object):
"""This class does blah blah."""
then:
>>> import x; help(x)
shows:
Help on module x:
NAME
x - This module does blah blah.
FILE
/tmp/x.py
CLASSES
__builtin__.object
Blah
class Blah(__builtin__.object)
| This class does blah blah.
|
| Data and other attributes defined here:
|
| __dict__ = <dictproxy object>
| dictionary for instance variables (if defined)
|
| __weakref__ = <attribute '__weakref__' of 'Blah' objects>
| list of weak references to the object (if defined)
As you see, the detailed information on the classes (and functions too, though I'm not showing one here) is already included from those components' docstrings; the module's own docstring should describe them very summarily (if at all) and rather concentrate on a concise summary of what the module as a whole can do for you, ideally with some doctested examples (just like functions and classes ideally should have doctested examples in their docstrings).
I don't see how metadata such as author name and copyright / license helps the module's user — it can rather go in comments, since it could help somebody considering whether or not to reuse or modify the module.
This will redirect the stderr (which is descriptor 2) to the file descriptor 1 which is the the stdout.
2>&1
Now when perform this you are redirecting the stdout to the file sample.s
myprogram > sample.s
Combining the two commands will result in redirecting both stderr and stdout to sample.s
myprogram > sample.s 2>&1
Redirect to /dev/null
if you want to completely silent your application.
myprogram >/dev/null 2>&1
I've spent the last few months messing around with Gemfiles and Gemfile.locks a lot whilst building an automated dependency update tool1. The below is far from definitive, but it's a good starting point for understanding the Gemfile.lock format. You might also want to check out the source code for Bundler's lockfile parser.
You'll find the following headings in a lockfile generated by Bundler 1.x:

These are dependencies sourced from a Rubygems server. That may be the main Rubygems index, at Rubygems.org, or it may be a custom index, such as those available from Gemfury and others. Within this section you'll see:
remote:
one or more lines specifying the location of the Rubygems index(es)specs:
a list of dependencies, with their version number, and the constraints on any subdependenciesGIT (optional)
These are dependencies sourced from a given git remote. You'll see a different one of these sections for each git remote, and within each section you'll see:
remote:
the git remote. E.g., [email protected]:rails/rails
revision:
the commit reference the Gemfile.lock is locked totag:
(optional) the tag specified in the Gemfilespecs:
the git dependency found at this remote, with its version number, and the constraints on any subdependenciesPATH (optional)
These are dependencies sourced from a given path
, provided in the Gemfile. You'll see a different one of these sections for each path dependency, and within each section you'll see:
remote:
the path. E.g., plugins/vendored-dependency
specs:
the git dependency found at this remote, with its version number, and the constraints on any subdependenciesPLATFORMS
The Ruby platform the Gemfile.lock was generated against. If any dependencies in the Gemfile specify a platform then they will only be included in the Gemfile.lock when the lockfile is generated on that platform (e.g., through an install).
DEPENDENCIES
A list of the dependencies which are specified in the Gemfile
, along with the version constraint specified there.
Dependencies specified with a source other than the main Rubygems index (e.g., git dependencies, path-based, dependencies) have a !
which means they are "pinned" to that source2 (although one must sometimes look in the Gemfile to determine in).
RUBY VERSION (optional)
The Ruby version specified in the Gemfile, when this Gemfile.lock was created. If a Ruby version is specified in a .ruby_version
file instead this section will not be present (as Bundler will consider the Gemfile / Gemfile.lock agnostic to the installer's Ruby version).
BUNDLED WITH (Bundler >= v1.10.x)
The version of Bundler used to create the Gemfile.lock. Used to remind installers to update their version of Bundler, if it is older than the version that created the file.
PLUGIN SOURCE (optional and very rare)
In theory, a Gemfile can specify Bundler plugins, as well as gems3, which would then be listed here. In practice, I'm not aware of any available plugins, as of July 2017. This part of Bundler is still under active development!
Accepted answer throws a java.lang.StackOverflowError
when calling the setParent
or addChild
methods.
Here's a slightly simpler implementation without those bugs:
public class MyTreeNode<T>{
private T data = null;
private List<MyTreeNode> children = new ArrayList<>();
private MyTreeNode parent = null;
public MyTreeNode(T data) {
this.data = data;
}
public void addChild(MyTreeNode child) {
child.setParent(this);
this.children.add(child);
}
public void addChild(T data) {
MyTreeNode<T> newChild = new MyTreeNode<>(data);
this.addChild(newChild);
}
public void addChildren(List<MyTreeNode> children) {
for(MyTreeNode t : children) {
t.setParent(this);
}
this.children.addAll(children);
}
public List<MyTreeNode> getChildren() {
return children;
}
public T getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
private void setParent(MyTreeNode parent) {
this.parent = parent;
}
public MyTreeNode getParent() {
return parent;
}
}
Some examples:
MyTreeNode<String> root = new MyTreeNode<>("Root");
MyTreeNode<String> child1 = new MyTreeNode<>("Child1");
child1.addChild("Grandchild1");
child1.addChild("Grandchild2");
MyTreeNode<String> child2 = new MyTreeNode<>("Child2");
child2.addChild("Grandchild3");
root.addChild(child1);
root.addChild(child2);
root.addChild("Child3");
root.addChildren(Arrays.asList(
new MyTreeNode<>("Child4"),
new MyTreeNode<>("Child5"),
new MyTreeNode<>("Child6")
));
for(MyTreeNode node : root.getChildren()) {
System.out.println(node.getData());
}
Try to delete the app.iml in your project directory and restart android studio
You might actually look into the internationally standardized format E.164, recommended by Twilio for example (who have a service and an API for sending SMS or phone-calls via REST requests).
This is likely to be the most universal way to store phone numbers, in particular if you have international numbers work with.
You can use phonenumber_field
library. It is port of Google's libphonenumber library, which powers Android's phone number handling
https://github.com/stefanfoulis/django-phonenumber-field
In model:
from phonenumber_field.modelfields import PhoneNumberField
class Client(models.Model, Importable):
phone = PhoneNumberField(null=False, blank=False, unique=True)
In form:
from phonenumber_field.formfields import PhoneNumberField
class ClientForm(forms.Form):
phone = PhoneNumberField()
Get phone as string from object field:
client.phone.as_e164
Normolize phone string (for tests and other staff):
from phonenumber_field.phonenumber import PhoneNumber
phone = PhoneNumber.from_string(phone_number=raw_phone, region='RU').as_e164
One note for your model: E.164 numbers have a max character length of 15.
To validate, you can employ some combination of formatting and then attempting to contact the number immediately to verify.
I believe I used something like the following on my django project:
class ReceiverForm(forms.ModelForm):
phone_number = forms.RegexField(regex=r'^\+?1?\d{9,15}$',
error_message = ("Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed."))
EDIT
It appears that this post has been useful to some folks, and it seems worth it to integrate the comment below into a more full-fledged answer. As per jpotter6, you can do something like the following on your models as well:
models.py:
from django.core.validators import RegexValidator
class PhoneModel(models.Model):
...
phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed.")
phone_number = models.CharField(validators=[phone_regex], max_length=17, blank=True) # validators should be a list
<script>
var deg = 0
function rotate(id)
{
deg = deg+45;
var txt = 'rotate('+deg+'deg)';
$('#'+id).css('-webkit-transform',txt);
}
</script>
What I do is something very easy... declare a global variable at the start... and then increment the variable however much I like, and use .css of jquery to increment.
<context:annotation-config>
declares support for general annotations such as @Required
, @Autowired
, @PostConstruct
, and so on.
<mvc:annotation-driven />
declares explicit support for annotation-driven MVC controllers (i.e. @RequestMapping
, @Controller
, although support for those is the default behaviour), as well as adding support for declarative validation via @Valid
and message body marshalling with @RequestBody
/ResponseBody
.
Simply use This:
driver.find_elements_by_xpath('//*[text() = "My Button"]')
In C, fgets(), and you need to know the maximum size to prevent truncation.
it's simple , and it's really worked for me .
run you wamp server => click right mouse button => and click on "put online"
then open your cmd as an administrateur , and pass in this commande word
ipconfig => and press enter
then lot of adresses show-up , then you have just to take the first one , it's look like this example: Adresse IPv4. . . . . . . . . . . . . .: 192.168.67.190
well done ! , that's the adresse, that you will use to cennecte to your wampserver in local.
You are trying to read the value of your checkbox before it is loaded. The script runs before the checkbox exists. You need to call your script when the page loads:
<body onload="dosomething()">
Example:
http://jsfiddle.net/jtbowden/6dx6A/
You are also missing a semi-colon after your first assignment.
Add a system variable named "node", with value of your node path. It solves my problem, hope it helps.
Reload the datasource of your grid after the update
myGrid.ItemsSource = null;
myGrid.ItemsSource = myDataSource;
To add to the previous explanations, static method calls are bound to a specific method at compile-time, which rather rules out polymorphic behavior.
We can use pathlib
; .glob
still doesn't support globbing multiple arguments or within braces (as in POSIX shells) but we can easily filter
the result.
For example, where you might ideally like to do:
# NOT VALID
Path(config_dir).glob("*.{ini,toml}")
# NOR IS
Path(config_dir).glob("*.ini", "*.toml")
you can do:
filter(lambda p: p.suffix in {".ini", ".toml"}, Path(config_dir).glob("*"))
which isn't too much worse.
You could git fetch origin
to update the remote branch in your repository to point to the latest version. For a diff against the remote:
git diff origin/master
Yes, you can use caret notation as well.
If you want to accept the remote changes:
git merge origin/master
Pure JSP comments look like this:
<%-- Comment --%>
So if you want to retain the "=
".you could do something like:
<%--= map.size() --%>
The key thing is that <%=
defines the beginning of an expression, in which you can't leave the body empty, but you could do something like this instead if the pure JSP comment doesn't appeal to you:
<% /*= map.size()*/ %>
Code Conventions for the JavaServer Pages Technology Version 1.x Language has details about the different commenting options available to you (but has a complete lack of link targets, so I can't link you directly to the relevant section - boo!)
For multiple columns you can do:
df = pd.DataFrame(np.zeros([nrow, ncol])*np.nan)
Go to your info.plist and check the key "Application does not run in background". This time when the user clicks the home button, the application exits completely.

Enabling SQL Server Service Broker requires a database lock. Stop the SQL Server Agent and then execute the following:
USE master ;
GO
ALTER DATABASE [MyDatabase] SET ENABLE_BROKER ;
GO
Change [MyDatabase] with the name of your database in question and then start SQL Server Agent.
If you want to see all the databases that have Service Broker enabled or disabled, then query sys.databases, for instance:
SELECT
name, database_id, is_broker_enabled
FROM sys.databases
Just add in: border-bottom: none;

Since I've asked this question, I've started using python-symmetric-jsonrpc. It is quite good, can be used between python and non-python software and follow the JSON-RPC standard. But it lacks some examples.
I eventually used:
weather["Temp"] = weather["Temp"].convert_objects(convert_numeric=True)
It worked just fine, except that I got the following message.
C:\ProgramData\Anaconda3\lib\site-packages\ipykernel_launcher.py:3: FutureWarning:
convert_objects is deprecated. Use the data-type specific converters pd.to_datetime, pd.to_timedelta and pd.to_numeric.
Yes, calling System.gc() doesn't guarantee that it will run, it's a request to the JVM that may be ignored. From the docs:
Calling the gc method suggests that the Java Virtual Machine expend effort toward recycling unused objects
It's almost always a bad idea to call it because the automatic memory management usually knows better than you when to gc. It will do so when its internal pool of free memory is low, or if the OS requests some memory be handed back.
It might be acceptable to call System.gc() if you know that it helps. By that I mean you've thoroughly tested and measured the behaviour of both scenarios on the deployment platform, and you can show it helps. Be aware though that the gc isn't easily predictable - it may help on one run and hurt on another.
There's always a lowercase "v". But seriously, aside from Unicode, all I can find would be &darr

You need to follow these steps before the token authentication
Create a Cluster Admin service account
kubectl create serviceaccount dashboard -n default
Add the cluster binding rules to your dashboard account
kubectl create clusterrolebinding dashboard-admin -n default --clusterrole=cluster-admin --serviceaccount=default:dashboard
Get the secret token with this command
kubectl get secret $(kubectl get serviceaccount dashboard -o jsonpath="{.secrets[0].name}") -o jsonpath="{.data.token}" | base64 --decode
Choose token authentication in the Kubernetes dashboard login page
Now you can able to login
I'd like to add that of the three algoritms mentioned so far (mergesort, quicksort and heap sort) only mergesort is stable. That is, the order does not change for those values which have the same key. In some cases this is desirable.
But, truth be told, in practical situations most people need only good average performance and quicksort is... quick =)
All sort algorithms have their ups and downs. See Wikipedia article for sorting algorithms for a good overview.
Replication is not very hard to create.
Here's some good tutorials:
http://www.ghacks.net/2009/04/09/set-up-mysql-database-replication/
http://dev.mysql.com/doc/refman/5.5/en/replication-howto.html
http://www.lassosoft.com/Beginners-Guide-to-MySQL-Replication
Here some simple rules you will have to keep in mind (there's more of course but that is the main concept):
This way, you will avoid errors.
For example: If your script insert into the same tables on both master and slave, you will have duplicate primary key conflict.
You can view the "slave" as a "backup" server which hold the same information as the master but cannot add data directly, only follow what the master server instructions.
NOTE: Of course you can read from the master and you can write to the slave but make sure you don't write to the same tables (master to slave and slave to master).
I would recommend to monitor your servers to make sure everything is fine.
Let me know if you need additional help
Once I also got that same type of error.
I.E:
C:\oracle\product\10.2.0\db_2>SQLPLUS SYS AS SYSDBA
Error 6 initializing SQL*Plus
Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
This error is occurring as the home path is not correctly set. To rectify this, if you are using Windows, run the below query:
C:\oracle\product\10.2.0\db_2>SET ORACLE_HOME=C:\oracle\product\10.2.0\db_2
C:\oracle\product\10.2.0\db_2>SQLPLUS SYS AS SYSDBA

Or if you are using Linux, then replace set
with export
for the above command like so:
C:\oracle\product\10.2.0\db_2>EXPORT ORACLE_HOME='C:\oracle\product\10.2.0\db_2'
C:\oracle\product\10.2.0\db_2>SQLPLUS SYS AS SYSDBA

What ended up finally working for me was to add the remote repository name to the git fetch

git fetch core
Now you can see all of them like this:

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
If you want to use a specific transform function, then all you need to do is include that function in the value. For example:
$('.user-text').css('transform', 'scale(' + ui.value + ')');
Secondly, browser support is getting better, but you'll probably still need to use vendor prefixes like so:
$('.user-text').css({
'-webkit-transform' : 'scale(' + ui.value + ')',
'-moz-transform' : 'scale(' + ui.value + ')',
'-ms-transform' : 'scale(' + ui.value + ')',
'-o-transform' : 'scale(' + ui.value + ')',
'transform' : 'scale(' + ui.value + ')'
});
jsFiddle with example: http://jsfiddle.net/jehka/230/
Set min-width: inherit /* Reset the min-width */
Try this. It will work.
$startDatedt = strtotime($start_date)
$endDatedt = strtotime($end_date)
$usrDatedt = strtotime($date_from_user)
if( $usrDatedt >= $startDatedt && $usrDatedt <= $endDatedt)
{
//..falls within range
}
The following is my take on the problem. This directive would compare against a form value instead of the scope.
'use strict';
(function () {
angular.module('....').directive('equals', function ($timeout) {
return {
restrict: 'A',
require: ['^form', 'ngModel'],
scope: false,
link: function ($scope, elem, attrs, controllers) {
var validationKey = 'equals';
var form = controllers[0];
var ngModel = controllers[1];
if (!ngModel) {
return;
}
//run after view has rendered
$timeout(function(){
$scope.$watch(attrs.ngModel, validate);
$scope.$watch(form[attrs.equals], validate);
}, 0);
var validate = function () {
var value1 = ngModel.$viewValue;
var value2 = form[attrs.equals].$viewValue;
var validity = !value1 || !value2 || value1 === value2;
ngModel.$setValidity(validationKey, validity);
form[attrs.equals].$setValidity(validationKey,validity);
};
}
};
});
})();
in the HTML one now refers to the actual form instead of the scoped value:
<form name="myForm">
<input type="text" name="value1" equals="value2">
<input type="text" name="value2" equals="value1">
<div ng-show="myForm.$invalid">The form is invalid!</div>
</form>
saving in any format is very much possible. Check following- http://docs.oracle.com/javase/tutorial/uiswing/components/filechooser.html
2ndly , What exactly you are expecting the save dialog to work , it works like that, Opening a doc file is very much possible- http://srikanthtechnologies.com/blog/openworddoc.html
Try this:
TypeScript file code:
(<HTMLInputElement>document.getElementById("name")).value
HTML code:
<input id="name" type="text" #name />
As some of my servers are on an old Ubuntu LTS versions, I can't easily upgrade git to the latest version (which supports the -C option as described in some answers).
This trick works well for me, especially because it does not have the side effect of some other answers that leave you in a different directory from where you started.
pushd /X/Y
git pull
popd
Or, doing it as a one-liner:
pushd /X/Y; git pull; popd
Both Linux and Windows have pushd and popd commands.
Try this:
Custom formula is
=countif(A:A,A1)>1
(or change A
to your chosen column)A1:A100
).Anything written in the A1:A100 cells will be checked, and if there is a duplicate (occurs more than once) then it'll be coloured.
For locales using comma (,
) as a decimal separator, the argument separator is most likely a semi-colon (;
). That is, try: =countif(A:A;A1)>1
, instead.
For multiple columns, use countifs
.
Instead of tying myself in a knot with hard-to-write and hard-to-maintain CSS (that also needs careful cross-browser validation!) I find it far better to give up on CSS and use instead wonderfully simple HTML 1.0:
<table id="outerDiv" cellpadding="0" cellspacing="0" border="0">
<tr>
<td valign="middle" id="innerDiv">
</td>
</tr>
</table>
This accomplishes everything the original poster wanted, and is robust and maintainable.
How does the virtual keyword work?
Assume that Man is a base class, Indian is derived from man.
Class Man
{
public:
virtual void do_work()
{}
}
Class Indian : public Man
{
public:
void do_work()
{}
}
Declaring do_work() as virtual simply means: which do_work() to call will be determined ONLY at run-time.
Suppose I do,
Man *man;
man = new Indian();
man->do_work(); // Indian's do work is only called.
If virtual is not used, the same is statically determined or statically bound by the compiler, depending on what object is calling. So if an object of Man calls do_work(), Man's do_work() is called EVEN THOUGH IT POINTS TO AN INDIAN OBJECT
I believe that the top voted answer is misleading - Any method whether or not virtual can have an overridden implementation in the derived class. With specific reference to C++ the correct difference is run-time (when virtual is used) binding and compile-time (when virtual is not used but a method is overridden and a base pointer is pointed at a derived object) binding of associated functions.
There seems to be another misleading comment that says,
"Justin, 'pure virtual' is just a term (not a keyword, see my answer below) used to mean "this function cannot be implemented by the base class."
THIS IS WRONG! Purely virtual functions can also have a body AND CAN BE IMPLEMENTED! The truth is that an abstract class' pure virtual function can be called statically! Two very good authors are Bjarne Stroustrup and Stan Lippman.... because they wrote the language.
iframe now supports srcdoc which can be used to specify the HTML content of the page to show in the inline frame.
table { width: 100%; }
Will not produce the exact result you are expecting, because of all the margins and paddings used in body. So IF scripts are OKAY, then use Jquery.
$("#tableid").width($(window).width());
If not, use this snippet
<style>
body { margin:0;padding:0; }
</style>
<table width="100%" border="1">
<tr>
<td>Just a Test
</td>
</tr>
</table>
You will notice that the width is perfectly covering the page.
The main thing is too nullify the margin
and padding
as I have shown at the body, then you are set.
transferring file from local to remote host
scp -i (path of your key) (path for your file to be transferred) (username@ip):(path where file to be copied)
e.g scp -i aws.pem /home/user1/Desktop/testFile ec2-user@someipAddress:/home/ec2-user/
P.S. - ec2-user@someipAddress of this ip address should have access to the destination folder in my case /home/ec2-user/
the problem with ping is if the host is not alive often your local machine will return an answer that the pinged host is not available, thus the errorcode of ping will be 0 and your code will run in error because not recognizing the down state.
better do it this way
ping -n 4 %1 | findstr TTL
if %errorlevel%==0 (goto :eof) else (goto :error)
this way you look for a typical string ttl which is always in the well done ping result and check error on this findstr instead of irritating ping
overall this looks like this:
@echo off
SetLocal
set log=path/to/logfile.txt
set check=path/to/checkfile.txt
:start
echo. some echo date >>%log%
:check
for /f %%r in (%check%) do (call :ping %%r)
goto :eof
:ping
ping -n 4 %1 | findstr TTL
if %errorlevel%==0 (goto :eof) else (goto :error)
:error
echo. some errormessage to >>%log%
echo. some blat to mail?
:eof
echo. some good message to >>%log%
You can build on the command line with ant. See this guide.
Then, you can install it by using adb
on the command line.
adb install -r MyApp.apk
The -r
flag is to replace the existing application.
I did not have much success with the above setTimeout
methods in Firefox.
Instead of a setTimeout, I've used an onload function:
window.onload = function () {
if (location.hash) {
window.scrollTo(0, 0);
}
};
It's still very glitchy, unfortunately.
Use .keyup
instead of keypress.
Also use $(this).val()
or just this.value
to access the current input value.
DEMO here
Info about .keypress
from jQuery docs,
The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except in the case of key repeats. If the user presses and holds a key, a keydown event is triggered once, but separate keypress events are triggered for each inserted character. In addition, modifier keys (such as Shift) trigger keydown events but not keypress events.
A solution suggested by my girlfriend is a variation of merge sort. The only modification is that during the merge step, just disregard duplicated values. This solution would be as well O(n log n). In this approach, the sorting/duplication removal are combined together. However, I'm not sure if that makes any difference, though.
It is possible using ssh. Python accepts hyphen(-) as argument to execute the standard input,
cat hello.py | ssh [email protected] python -
Run python --help for more info.
The Podfile.lock
keeps track of the resolved versions of each Pod installed. If you want to double check that FlurrySDK is using 4.2.3, check that file.
Note: You should not edit this file. It is auto-generated when you run pod install
or pod update
There is extensive paramiko API documentation you can find at: http://docs.paramiko.org/en/stable/index.html
I use the following method to execute commands on a password protected client:
import paramiko
nbytes = 4096
hostname = 'hostname'
port = 22
username = 'username'
password = 'password'
command = 'ls'
client = paramiko.Transport((hostname, port))
client.connect(username=username, password=password)
stdout_data = []
stderr_data = []
session = client.open_channel(kind='session')
session.exec_command(command)
while True:
if session.recv_ready():
stdout_data.append(session.recv(nbytes))
if session.recv_stderr_ready():
stderr_data.append(session.recv_stderr(nbytes))
if session.exit_status_ready():
break
print 'exit status: ', session.recv_exit_status()
print ''.join(stdout_data)
print ''.join(stderr_data)
session.close()
client.close()
The W3C has a good introduction.
In short:
HTML is a text markup language. Text means any characters, not just ones in ASCII.
You can also represent any unicode character with ASCII
What about
string[] filesPNG = Directory.GetFiles(path, "*.png");
string[] filesJPG = Directory.GetFiles(path, "*.jpg");
string[] filesJPEG = Directory.GetFiles(path, "*.jpeg");
int totalArraySizeAll = filesPNG.Length + filesJPG.Length + filesJPEG.Length;
List<string> filesAll = new List<string>(totalArraySizeAll);
filesAll.AddRange(filesPNG);
filesAll.AddRange(filesJPG);
filesAll.AddRange(filesJPEG);
You could use escapeJavaStyleString
from org.apache.commons.lang.StringEscapeUtils
.
Got the error (in the function init) with the following code ;
"use strict" ;
var hdr ;
function init(){ // called on load
hdr = document.getElementById("hdr");
}
... while using the stock browser on a Samsung galaxy Fame ( crap phone which makes it a good tester ) - userAgent ; Mozilla/5.0 (Linux; U; Android 4.1.2; en-gb; GT-S6810P Build/JZO54K) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30
The same code works everywhere else I tried including the stock browser on an older HTC phone - userAgent ; Mozilla/5.0 (Linux; U; Android 2.3.5; en-gb; HTC_WildfireS_A510e Build/GRJ90) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1
The fix for this was to change
var hdr ;
to
var hdr = null ;
You can use statement body in lamba expression for IEnumerable collections. try this one:
Obj[] myArray = objects.AsEnumerable().Select(o =>
{
var someLocalVar = o.someVar;
return new Obj()
{
Var1 = someLocalVar,
Var2 = o.var2
};
}).ToArray();
Notice:
Think carefully when using this method, because this way, you will have all query result in memory, that may have unwanted side effects on the rest of your code.
if you are using the MySQLWorkbench you have the option to change the to change the query_alloc_block_size= 16258 and save it.
Step 1. click on the options file
at the left side.
Step 2: click on General
and select the checkBox
of query_alloc_block_size and increase their size. for example change 8129 --> 16258
Call cURL from your console app is not a good idea.
But you can use TinyRestClient which make easier to build requests :
var client = new TinyRestClient(new HttpClient(),"https://api.repustate.com/");
client.PostRequest("v2/demokey/score.json").
AddQueryParameter("text", "").
ExecuteAsync<MyResponse>();
If you are reencoding in your ffmpeg command line, that may be the reason why it is CPU intensive. You need to simply copy the streams to the single container. Since I do not have your command line I cannot suggest a specific improvement here. Your acodec and vcodec should be set to copy is all I can say.
EDIT: On seeing your command line and given you have already tried it, this is for the benefit of others who come across the same question. The command:
ffmpeg -i rtsp://@192.168.241.1:62156 -acodec copy -vcodec copy c:/abc.mp4
will not do transcoding and dump the file for you in an mp4. Of course this is assuming the streamed contents are compatible with an mp4 (which in all probability they are).
SELECT *
FROM ...
WHERE EXISTS(SELECT 1
FROM sys.columns c
WHERE c.[object_id] = OBJECT_ID('dbo.Tags')
AND c.name = 'ModifiedByUser'
)
Alternative way to check would be:
if (!$('#myModal').is(':visible')) {
// if modal is not shown/visible then do something
}
You're storing the .Text
properties of the textboxes directly into the database, this doesn't work. The .Text
properties are String
s (i.e. simple text) and not typed as DateTime
instances. Do the conversion first, then it will work.
Do this for each date parameter:
Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) )
Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse
or DateTime.TryParseExact
, but implementing that is an exercise for the reader.
Add this code where you want to click and load Fragment. I hope it's work for you.
Fragment fragment = new yourfragment();
FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragment_container, fragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
A simple solution that worked for me is to close the Terminal and restart it.
The default behaviour of divs is to take the full width available in their parent container.
This is the same as if you'd give the inner divs a width of 100%.
By floating the divs, they ignore their default and size their width to fit the content. Everything behind it (in the HTML), is placed under the div (on the rendered page).
This is the reason that they align theirselves next to each other.
The float CSS property specifies that an element should be taken from the normal flow and placed along the left or right side of its container, where text and inline elements will wrap around it. A floating element is one where the computed value of float is not none.
Source: https://developer.mozilla.org/en-US/docs/Web/CSS/float
Get rid of the float, and the divs will be aligned under each other.
If this does not happen, you'll have some other css on divs or children of wrapper defining a floating behaviour or an inline display.
If you want to keep the float, for whatever reason, you can use clear
on the 2nd div to reset the floating properties of elements before that element.
clear
has 5 valid values: none | left | right | both | inherit
. Clearing no floats (used to override inherited properties), left or right floats or both floats. Inherit means it'll inherit the behaviour of the parent element
Also, because of the default behaviour, you don't need to set the width and height on auto.
You only need this is you want to set a hardcoded height/width. E.g. 80% / 800px / 500em / ...
<div id="wrapper">
<div id="inner1"></div>
<div id="inner2"></div>
</div>
CSS is
#wrapper{
margin-left:auto;
margin-right:auto;
height:auto; // this is not needed, as parent container, this div will size automaticly
width:auto; // this is not needed, as parent container, this div will size automaticly
}
/*
You can get rid of the inner divs in the css, unless you want to style them.
If you want to style them identicly, you can use concatenation
*/
#inner1, #inner2 {
border: 1px solid black;
}
You urls are not in the same repository, so you can't do it with the svn diff
command.
svn: 'http://svn.boost.org/svn/boost/sandbox/boost/extension' isn't in the same repository as 'http://cloudobserver.googlecode.com/svn'
Another way you could do it, is export each repos using svn export
, and then use the diff command to compare the 2 directories you exported.
// Export repositories
svn export http://svn.boost.org/svn/boost/sandbox/boost/extension/ repos1
svn export http://cloudobserver.googlecode.com/svn/branches/v0.4/Boost.Extension.Tutorial/libs/boost/extension/ repos2
// Compare exported directories
diff repos1 repos2 > file.diff
