How do I change the MessageBox location?

问题

I need to change the message box location. I don't want it to be in the center of the page.

MessageBox.Show("Hello");

回答1:

Normally, you can't change startup location of standard message box.

Solutions for your question:

• Create your own custom message box. There is example of creation on CodeProject.
• Complicated way using Windows Hook Procedure (WinAPI).

回答2:

You will need to create a new form that inherits from the MessageBox form. That is the only way to access the position properties.

There is a way to change the location, but its way too complicated for such a small task.
If you really need to change its location, you could display it, then use GetForegroundWindow to get a window handle, then MoveWindow to your desired location.
But, as I already mensioned, this is way too complicated.
Just create your own form with a label on it an a "OK" button. Set the button as the default window button, and then, in Form1 do MyWndName.ShowDialog();

What you can do is to create a new window, set the property AllowsTransparency to true and set the Background to Transparent. In that window you can put a TextBlock, or a label and also add Yes/No Buttons. Set the location of this window using Canvs.SetTop(Window,TopPosition) and Canvas.SetLeft(Window,LeftPosition). next, call the window with the method Show() or ShowDialog().
