Hello,
I noticed today that the System.Runtime.InteropServices.Marshal class has overloads of the Copy method in the form: Copy(IntPtr source, int[] destination, int startIndex, int length);, but there are no overloads for unsigned data (e.g. uint). I wonder why?
Thanks in advance.
|
|
|
|
|
Perhaps because uint type is not CLS[^]-compliant.
|
|
|
|
|
Thanks. But I'm wondering, since I'm creating a class library with methods that take uint, does this mean the library will not be usable except in C#?
|

You dont have problem with existing languages like c++.net or vb.net. But someone may develop a language that uses .net components, without support for unsigned integers. For such senarios stands the CLS.

Hello @ all,
i have a problem: for our application (C#) we have create a language logic.
When you press CTRL and click with a DoubleRightMouseClick on a Control (exp: Label or other controls), a function will be called. For the most Controls no Problem, but i have a big problem to catch a DoubleRigthtMouseClick for the WindowsForm CheckBox....
What can i do??? MSDN says that the right MouseClick is not supported for checkboxes....
Maybe you can help me.
Thank you
Steven

Right click and Double click functionality are disabled in the source for the check box so you'll heve to create your own.
This should get you started
public class MyCheck : CheckBox
{
[Browsable(true)]
public new event MouseEventHandler MouseDoubleClick;
public MyCheck()
{
SetStyle(ControlStyles.StandardClick |
ControlStyles.StandardDoubleClick, true);
}
protected override void OnMouseDoubleClick(MouseEventArgs e)
{
if (e.Button== MouseButtons.Right && MouseDoubleClick != null)
MouseDoubleClick(this, e);
}
}
You'll need to stop the right click from changing the CheckedState though and there's probably other functionality that maybe a little strange or broken so test it thoroughly.

Have a look at Christian Graus' Image Processing for Dummies with C#[^] series. That should get you started

I am writing a windows application to upload file by using Backgroundworker and EventWaitHandle. But it doesn't get any respond after run the line 'handle.WaitOne();'. Can anyone help?
<br />
private void btnUpload_Click(object sender, EventArgs e)<br />
{<br />
BackgroundWorker worker = new BackgroundWorker();<br />
worker.DoWork += new DoWorkEventHandler(worker_DoWork);<br />
worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(worker_RunWorkerCompleted);<br />
MessageBox.Show("FTP 1");<br />
worker.RunWorkerAsync();<br />
MessageBox.Show("FTP 2");<br />
handle.WaitOne();
MessageBox.Show("FTP 3");<br />
}<br />
static void worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)<br />
{<br />
MessageBox.Show("FTP 4");<br />
handle.Set();<br />
}<br />
<br />

One of the nice things about BackgroundWorker is that RunWorkerCompleted is raised on the UI thread. In your example, you have blocked the UI thread with the call to handle.WaitOne(), so worker_RunWorkerCompleted can never run and signal your handle 
Also, the point of BackgroundWorker is to avoid blocking the UI thread. Why are you blocking it?
