How do I change the MessageBox location?

Question

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

MessageBox.Show(\"Hello\");

Answer 1

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();

Answer 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.

Answer 3

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().

Answer 4

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).

Answer 5

Since I already use AutoIt for several other tasks in my project so I just create another thread to move the Message box

using System.Threading;
using AutoIt;
//Namespace, class, function stuffs
//New thread BEFORE create message box - safety measure
Thread autoItThread = new Thread(delegate ()
                {
                    AutoItX.WinWait("New Message box");
                    AutoItX.WinMove("New Message box", "This box will be moved", 400, 300);
                });
                autoItThread.Start();
MessageBox.Show("This box will be moved", "New Message box");

Please note

• The coordinate 400,300 is absolute. 0,0 will be top left corner.
• This is screen-dependent. If you want to be exact, other code to determine location is needed
• This task is to change the absolute position of the Message box rather than move it.
• How to get/install AutoIt is not addressed here. Please look for instruction on that if you need to.
