As I know there is no API for this purpose. It is used very common, may be someone has his own code and want to share;)

Hello,
I'm new to C# .Net 2, though not to programming, and I'm having some trouble with an object I've created.
ProductStatus is an object that i have used implemented as a List<T> . It is filled from a database, each new record is a new ProductStatus.
My question is, how do I return a sepecific entry from the list, using <T>.Contains for instance, but without having to pass an entire ProductStatus in? For instance just passing in the Name, or it's ID number.
If anyone could recommend some reading about Generics and Collections in C#, that would be just fudgin awesom-o, too.
thanks

nevermind I used Dictionary<T> in the end.

For future reference, you can use the generic List's Find method. For example, if you had a list of strings, and you wanted to find the first string starting with "hello", it'd look like this:
string startsWithHello = myStrings.Find(MyCriteriaFunction);
...
bool MyCriteriaFunction(string input)
{
return input.StartsWith("hello");
}
Alternately, you can use anonymous methods to do this in a more concise manner:
string startsWithHello = myStrings.Find(delegate(string input)
{
return input.StartsWith("hello");
});
The next version of C# includes syntax for writing lambda expressions, which simplifies this further:
string startsWithHello = myStrings.Find(s => s.StartsWith("hello"));
Additionally, the next version of the .NET framework will include System.Query.dll, allowing for language integrated query syntax. C# 3 takes advantage of this, and will allow you to write something like this:
string startsWithHello = from s in myStrings where s.StartsWith("hello");

If you have an VS project, open the project settings, select the first tab called Application and choose Class Library as output type.
If you want to compile with csc.exe directly take a look at its command line options in MSDN. There is one (/o if I recall correctly) that allows you to select the output type.

if you have extra code in the same project remove that code or create a new class library project and copy your files in that projects folder include them build it and you have it
if you want the release version of your dll then build it in release mode and you have it

Hi,
Within my background worker's DO_WORK method, I have following code,
......................................................<br />
webBrowser1.navigate("http://www.google.com");<br />
while(weBrowser1.ReadyState != RedyState.Complete)<br />
Application.DoEvents()<br />
....................................................
Now, when the background worker is being executed, webbrowser1 is being loaded with the mentioned website nicely without any problem. But the problem is, when it checks the ReadyState, it stays uninitialized forever and never reaches ReadyState.Complete and thus, the thread never exists. I checked the code with so many website url so there is no chance that I am having problem to load google.com.
I dont have this problem when the same code is being executed in the standard main thread. Only problem when the code is being run in a background worker thread.
Please help... and your co-operation is appreciated.

Why don't you register to the WebBrowser.DocumentCompleted event instead of actively waiting for the ReadyState property to become Complete.?
It's always complicated to access visual controls from threads other the one they were created on. Take a look at this article to get a general idea how to bypass. What's up with BeginInvoke?[^]
Furthermore the call of Application.DoEvents from a worker thread isn't necessary as the use of the worker thread already keeps your application responsive (in a much nicer way than DoEvents).

Should that not be ReadyState.Complete?

May be the problem is using " Application.DoEvents()" in the delegate function. Using this method outside of the delegate function or DoWork method may be useful

Hello,
Let's say I have a variable named: someVar which contains the following:
href wow nice this <a href="cp.com">cow duck john</a> text etc
And I want to replace: "href" with "link". I can't do:
someVar.Replace("href", "link");
Because that will change: <a href="cp.com">!
So, how can I replace all the occurances of "href" when it's not part of an HTML tag?
Please help.
|
|
|
|
|
hi
for something simple like that just try this:
someVar = someVar.Replace("<a href","|||||||").Replace("href","link").Replace("|||||||","<a href");
the ||||||| can be replaced by anything as long as it's unique
hope that helps.
|
|

Try this REGEX, I hope it will be useful. You can use any variable instead of link word in the following snippet.
string ResultString = null;<br />
try {<br />
ResultString = Regex.Replace(someVar, "(>.*?)(href)(.*?<)", "$1link$3",<br />
RegexOptions.Singleline | RegexOptions.IgnoreCase | RegexOptions.Multiline);<br />
} catch (ArgumentException ex) {<br />
}

I was wondering if there is a way to detect if a process is executed, preferably with an event.
|
|
|
|

Hi,
You can easily create event handler for a process instance. IF you use Process Instance from Design mode, then you will see that, there is an event named EXITED available in the event list for that instance of component. If you are creating your process within your code, then you can use the following snippet.
........................................................................................<br />
<br />
System.Diagnostics.Process myProcess = new System.Diagnostics.Process();<br />
myProcess.Exited += new EventHandler(myProcess_Exited);<br />
<br />
void myProcess_Exited(object sender, EventArgs e)<br />
{<br />
throw new Exception("The method or operation is not implemented.");<br />
}<br />
<br />

i need to access a file in one form and print the contents of the file to the textbox which is in other form....

Use a delegate, or pass the form object of the parent to the child

My program edits text-based files full of nonsense.
I finally cleared up my program's commandline args thing to open a file by double-clicking on the file (with the appropriate made-up extension belonging to it).
However, when the user double-clicks on its file for the first time, and Windows asks the user what program to use to open the file (because Windows doesn't recognize the extension at first), my program has no name in the list! Please see this image:

How do I get the dialog to have my program's name in it?
By the way, I use csc.exe directly to compile it.

try write values in AssemblyInfo.cs file, like AssemblyTitle().. and so on.

I added that line, but didn't see a change, so I started digging around in my registry. I simply modified the line that was already there:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam\MUICache]<br />
" program path here"="program's title or name"
And now it works fine.
Thank you, though! I'm sure your way would have worked if I had done it in the first place and restarted or something...
