A Label control that its text can be selected with the mouse

Hi,

Is there a way to allow the Label control to select its text with the mouse
by the user?
I've looked at the Label's properties but I couldn't find anything making
this possible.
Am I missing something here? Well, it can be done with a Textbox control,
but the problem with this approach is that when I click on a read only
Textbox, a vertical line is displayed inside it.
In short, I want something similar to internet browsers, where users can
select the text and copy it to the clipboard.

Thanks for your time,

Ben

You're have to use the Windows API to do this, hiding and showing the caret
according to TextBox events. See the following:

HideCaret fails, and when i call Marshal.GetLastWin32Error, it
returns a value of 5, which i think means access denied.
How can i make this work please?

Thanks,
Ben

The declaration at pinvoke.net didn't have SetLastError=true in the
DllImport attribute. Did you add that? If not, you can't expect
GetLastWin32Error to return the right error code.

Hi Mattias,

Yes, I did add "SetLastError=true" to the attribute.
I have no idea why I get access denied when I call HideCaret.

Thanks,
Ben
