Editing .CS codefile through reflection?

Hello,

Wondering if anyone has any insight into how one would edit code programmatically through reflection. For example I'd like to change a method's custom attribute setting if certain criteria apply.

All I need to know is if this is possible a hint on the call necessary to make this edit.

Thanks in advance!

Greetings!
I want to create project with video abilities.
Here is short description of my needs:
Application needs to be done with .NET Framework.
Application should consist from two parts:
Client application and server application have different functionality, but they both should work with web-cams installed on their sides (client and server sides).
First part is a client application.
Client application can connect to different web – cams and see content of web – cam.
User of client application can talk to server application using microphone and listens answer from server user.
Except this, client application should have ability to save video from server side.
Server application should have similar video abilities with client application.
I analyzed different technologies for my purpose and I lost one's the head in technologies.
Please suggest me what technology best suites for my project.
Thank you all for your attention for my question
Best Regards,
Alex

Set cursor into the TextBox after TextBox is being visible

Hi
I have a problem with set cursor into TextBoxes, which are usually unvisible.
After some events the TextBoxes I set some TextBoxes to visible. To set the cursor to the actually visible TextBox use Select() or Focus(), but the cursor doesn't change it's position and stay in the last TextBox, only after a minimize and maximaize action or change to the other programs and back to this program moved to the expected TextBox. Invalidate or Refresh and DoEvents cann't help. I think it's something wrong with exessive using of my internal events, because in a testprogram witout my events the cursor behave as I expected.

Scrolling in RichTextBox [modified]

Hi
after insertion some lines the vertical scroll is coming, but the RichTextBox still show the upper side and doesn't scroll to the last line and doesn't show the last inserted line. Should I get the count of lines and scroll line by line?
Info: This RichTextBox has't any focus. It's only a logging MultiLine-TextBox .

I had the same problem with a listbox: I do not know a way to have it scroll automatically
to keep the bottom line visible, so this is what I came up with (and I assume something
similar applies to a RichTextBox):

public void Output(string s) {
	lb.Items.Add(s);
	// force maximum vertical scroll unless mouse button is pressed
	// (so we can operate the lift to concentrate on some part of the output)
	if (Control.MouseButtons==MouseButtons.None) {
		lb.TopIndex=lb.Items.Count-1;
	}
}

BTW: the value for the top index is not correct
(it should actually be Items.Count - numberOfLinesVisibleInListbox)
but it works just fine as is, so why bother. (But the -1 is necessary).

ToolboxBitmap for CF component?

I'm sorry if I post this here, because I cannot find the thread about Compact Framework. Well, to the point. We know that we can use custom image as the toolbox item (Framework). We just use the attribute ToolboxBitmap to set the component/control icon. But at .NET Compact Framework 2.0 I cannot find the attribute like this, does anyone know alternate way to use custom icon for the component/control (on designer for sure not runtime).

Thanks for helping.

It looks likes it's not supported. BTW: The CF Forum is called "Mobile Development".

The alternative is to add a 16x16 pixel BMP as an embedded resource with the same name as the control class.

With namespace or not, e.g class name is "classA" in namespace "nsA", so on resource use "nsA.classA.bmp" or only "classA.bmp"?

Thanks for the reply.

Ok another problem with .NET Remoting. Sniff | :^)

Server create object in mode='singleton' by file configuration. Object has member 'parent_'.
Like this:

-----------------------------------------------------------------------
RemotingConfiguration.Configure(@"TestServer.exe.config", false); remoteobject_ = new RemoteObject();
remoteobject_.parent_=this
-----------------------------------------------------------------------

I tried connect to this object in client like this:

-----------------------------------------------------------------------
RemotingConfiguration.Configure(@"TestClient.exe.config", false);
WellKnownClientTypeEntry[] ClientEntries = RemotingConfiguration.GetRegisteredWellKnownClientTypes();
remoteobject_ = (RemoteObject)Activator.GetObject(typeof(TestRemothing.RemoteObject),ClientEntries[0].ObjectUrl);
-----------------------------------------------------------------------

and i noticed, that client work with other remote object than server. Why? How client can work with object, that already created by server?

ReaderWriterLock [modified]

21-Dec-06 10:03

By using this, what exactly is locked? A specifiek variable or the thread itself or the variables that have been modified with 'System.Threading.Interlocked.Increment'?

I THINK 'THE VARIABLES THAT HAVE BEEN MODIFIED BY THE THREAD'. WRIGHT?

If you have the following:

public static void Synchronization_WriterLock()
{
System.Threading.ReaderWriterLock oReaderWriterLock;
oReaderWriterLock = new System.Threading.ReaderWriterLock();

miCount = 0;

try
{
oReaderWriterLock.AcquireWriterLock(100);

try
{
System.Threading.Interlocked.Increment(ref miCount);
Console.WriteLine(miCount);
}

finally
{
oReaderWriterLock.ReleaseWriterLock();
}
}

catch (ApplicationException e)
{
Console.WriteLine("Failed to get a Writer Lock");
}
}

What locks what?
