Once a user edits the label in my listview control, I need to make sure that the label is in all upper case. So I'm using the AfterLabelEdit event to view what the new label is and to change it to upper case if I need to. Here is the code I've written:
private void AfterLabelEdit(object sender, System.Windows.Forms.LabelEditEventArgs e)
{
string labelText;
int ItemIndex;
labelText = e.Label;
ItemIndex = e.Item;
listView1.Items[ItemIndex].Text = labelText.ToUpper();
}
Unfortunately, this does not work. The label still will have lower case letters. Does anybody know what I'm missing here?

Using .NET Reflector, I found this code (in ListView.WmReflectNotify):
this.inLabelEdit = false;
NativeMethods.NMLVDISPINFO nmlvdispinfo1 = (NativeMethods.NMLVDISPINFO) m.GetLParam(typeof(NativeMethods.NMLVDISPINFO));
LabelEditEventArgs args2 = new LabelEditEventArgs(nmlvdispinfo1.item.iItem, nmlvdispinfo1.item.pszText);
this.OnAfterLabelEdit(args2);
m.Result = args2.CancelEdit ? IntPtr.Zero : ((IntPtr) 1);
if (!args2.CancelEdit && (nmlvdispinfo1.item.pszText != null))
{
this.Items[nmlvdispinfo1.item.iItem].Text = nmlvdispinfo1.item.pszText;
}
return;
As you can see, the new text of the ListViewItem is set after the AfterLabelEdit event, so any changes you make in the event handler will be overwritten.
I know I'm not solving your problem, but at least I'm telling you why it happens.

That definitely explains why my text is still in lower case.....but, thanks to Luis, I figured out how to do it. I was missing one line of code. After I set the label text in the listview control so that all the text is in upper case, I then cancel the edit so that the text that I want is not overwritten.
listView1.Items[ItemIndex].Text = LabelText.ToUpper();
e.CancelEdit = true;
Thanks for the help!!!

As has been already mentioned, the reason why that happens is because the label text is set after the event.
To counter that you just need to add one more line at the end of your code:
e.CancelEdit = true;
So your new code will look like:
private void listView1_AfterLabelEdit(object sender, System.Windows.Forms.LabelEditEventArgs e)
{
string labelText;
int ItemIndex;
labelText = e.Label;
ItemIndex = e.Item;
listView1.Items[ItemIndex].Text = labelText.ToUpper();
e.CancelEdit = true;
}

In a C# application, I want to kill another application. If I use the Process.Kill method, I get unpredictable behaviour on my PC that even forces me to re-logon.
Probably, the killed application leaves open resources.
If I use the Process.CloseMainWindow, the application displays a dialog asking for confirmation to exit. How do I respond to that from my C# application?
Are there other solutions?
Thanks in advance.

In the past I've always used the Process.Kill method and it never gave me any problems. Try posting some of your code so we can find out what you might be doing wrong. Here's how I've done it in the past:
Suppose you want to write a method that takes a string as a parameter and that sting is the name of the process you'd want to kill:
<br />
private void KillProcess(string processName)<br />
{<br />
Process[] processes = Process.GetProcessesByName(processName);<br />
<br />
foreach (Process p in processes)<br />
{<br />
p.kill()<br />
}<br />
}<br />

I have stripped my code as much as possible to isolate the problem.
If I try to kill another application, say notebook, it works fine.
So I think it must be rtrobo.exe leaving resources that causes troubles.
Note: this code is only used in debug mode.
static void Main(string[] args)
{
Process robotProcess = new Process();
robotProcess.StartInfo.FileName = @"C:\Program Files\Rational\Rational Test\rtrobo.exe";
robotProcess.StartInfo.Arguments = @"Test_001 /user admin /project e:\Sobek\TestcasesNew\Testcases.rsp /build 'Build 1' /NoLoginServices /logfolder Default /play /log Mylog /nolog";
robotProcess.Start();
// In debug mode, wait until rtrobo finishes startup.
Process [] procs = Process.GetProcessesByName( "rtrobo" );

Delete both of these posts and then repost your question, but this time, check the little box under the message window that says "Do not treat <'s as HTML tags".

Hi Guys,
I’m trying to determine when files are being copied on my system.
I started off with the File System Watcher component in .NET, but a copy can’t be inferred from any combination of create or change events. So that won’t work.
I wanted to try Copy Hook Handlers next, but it turns out that Copy Hook Handlers only work with folders or printer objects.
So my question is: Are there any API calls or anything else for that matter, which can be used to monitor copy events?
Thank you

A Copy operation from any source to your machine is no different than a Create file and Write to it. So, no, there's no way to tell the difference between a file Copy and an application just saving a document to the hard drive.

Hi all!
I have a small Interop question:
I have a COM object that takes a structure as in-parameter. One of the fields in the structure is an IID*. When doing this in C++ the code:
GUID rrid = __uuidof( _InterfaceName );
parStruct.riid = &rrid;
works fine.
How would I do this in C#? I have tried several things, but can´t get it to work. The type of the struct-field in C# is intPtr. And the only way I can find such a type, that I can think of, is:
Type t = typeof( _InterfaceName );
System.RuntimeTypeHandle h = t.TypeHandle;
parStruct.riid = h.Value;
But I guess that I am way off here.
Any one that can give me a hand here?
Regards
Mikke

Hi again!
I tried to create a C++ .Net project instead, just to try and find a work-around. When I took the COM objects needed and tried to import them into my brand new cpp project i got this error message:
TlbImp warning: The type library importer could not convert the signature for the member 'RobEventParams.riid'.
And a couple of other ones like this one for other similar parameter-structs with riid fields. What does that mean for me? Is it impossible to marshal something from .Net into this COM? The purpose is to set up a sink and recieve events from the COM object, to do this I should send a ref to an object that should recieve the events and the signature of an interface implemented in the receiver. It is the interface "signature" that is the riid, and also the problem here. When I execute my C# code above I get an exception telling me that "No such interface supported". Do I have to submit a non-.net method as a sink here?
Best regards again / Mikke

Hi! I have a listview, let's say with 4 columns, with fullrow selection.
When i select one row, i want to get the element from the second column.
Can you tell me how to do that?
I know how to get the element from the first column, but to get the other element's of the row selected is kind of a problem for me.
Thanks!

How to use C++ style cast ( reinterpret_cast ) in C# ???
In C++ context :
NMHDR* pNMHDR;
NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>( pNMHDR );
Please give me the answer.
Thanks.

There are no special casting operators in C# like static_cast, dynamic_cast or reinterpret_cast. Just use the normal casting operator, like
void SomeFunc(object obj)
{
MyType t = (MyType) obj;
}
Just remember that the CLR will never allow type casts that violate casting rules, so you really cannot simulate the effect of reinterpret_cast in C# or any .NET language.

In addition to the previous answer you can also use the as keyword.
The cast operator will throw an exception when the conversion is not possible, with as you'll get a null reference.
For example:
void MyFunc(object o)<br />
{<br />
MyType t = o as MyType;<br />
if (t == null)<br />
}
