MessageBox Centering

[Chuck]

Is there anyway to get a MessageBox to center in the parent form or in
the middle of a MDI parent? The .NET standard MessageBox is centered
on the screen area, not on the application.

Specifing the owner doesn't seem to work reliably in MDI applications
public static DialogResult Show(
IWin32Window owner,
string text
);

In 1.1 you had to use a WH_CALLWNDPROC hook and look for a
WM_INITDIALOG or write your own MessageBox routine

I hate it when you do MessageBox.Show() and the messagebox pops up in
the second display or in someother non-intutive location.

thanks,

Hi Chuck,

Thanks for your post.

MessageBox.Show method internally uses MessageBox win32 API to do the
actual work. This API does not provide any interface to change the message
box location. So MessageBox.Show did not provide any interface to control
its location

Hope it helps!

Hi,

MessageBoxes are centered on screen by default. If you find that
un-intuitive, you might try to center the parent form on screen, so
that the Messagebox now shows as centered on the parent form as well.

If that isn't possible, try a custom implementation of a Messagebox.

HTH,

Not being able to center dialog box's or dialog forms is one of those
really bad missing features in .Net.

I guess I will go back to using the API and Interop, I was hoping to
have a .Net solution.

I think the best example out there is:

Sometimes the users move the parent form, from one display to another.
I'd rather not recenter the parent when I have to display a message
box or modal form. I will go back to com interop.

Don't think it's possible. I built my own messagebox that I could control
and use it in several different projects.

Hi Chuck,

Thanks for your feedback.

As I stated in the original post, .Net MessageBox.Show() method only
encapsulates the Win32 MessageBox() API. So this issue is not due to the
limitation of .Net, but Win32 API.

Yes, because message box is also a win32 window, we can use all the win32
UI technology to manipulate it.
