Hello,
I have an MDI child, which I need to be opened as long as the mainframe
is opened. The problem is that the user can close it using the X button
in the form's top-right edge.
How can I make this button disappear, or at least disabled?
I'm using C# with .NET Framework 2.0.
Thanks a lot!

Just off the top of my head....
Override the WndProc so that you can trap the WM_NCHITTEST and WM_NCPAINT
messages.
Paint your own title bar without the close button in the handler for
WM_NCPAINT
Prevent the detection of the close button in the WM_NCHITTEST.

If you don't need the other icons from control box (minimize, maximize), you
can set the ControlBox property to false.
You can also override the Closing event of your form and cancel it (look at
closing reason and set e.Cancel = true;), which will not disable or let
disappear the button, but will not let anyone to close the form.

Hello,
Description: I create panels with some controls on a page
using a new panel button. One of the controls on each panel
is the "close panel" button that is supposed to close the
panel it is on. This works fine only if one closes the
panels from last panel. Otherwise two clicks is necessary
for the last panel - ie, if you press add 3 times, close 2
and then 3 - two clicks on 3 will be necessary.

Customer wants the Close (X)-button of the forms top right corner to be
Disabled or removed from Windows Form-application, which is made using
VB.NET, but leave MinimizeBox and MaximizeBox.
I think this is not so clever to do like this way, but have to do like
customer wants - so how to do this? It seems to be not just like
changing property like with MinimizeBox and MaximizeBox. Any succestions?

Thanks in advance!

I am wondering if there is a way to disable the "X" used to close the
Access application window? I know how to disable it for individual
forms, but I would like to disable it for the application in general
and force users to use a button on the switchboard to close (because I
run important code on the close of the database from that button).
Any ideas are always appreciated.
Thanks!

Hi again,
I'm new to VBA and would really appreciate your help.
I have disabled the "X" close button and created a Close button, which I want to disable as a Form_Dirty event. So that users can only Close the form if they haven't made changes or have Saved their changes.
However, as soon as I dirty the form, I get an error message pointing at this code:
Private Sub Form_Dirty(Cancel As Integer)
cmdClose.Enabled = False

I am currently writing an application and need to remove the close option from the form (The x button at the top right). I see that there are many examples of how to disable the close button and how to remove all the buttons. But for my application I would like to have only the minimize option available and thus the examples I have seen for VB.net will not help.
Does anybody know how to just remove the close button?
Thanks

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
