Control size of Message Box

[jwkNwA7f]

I have been reading Charles Petzoid's Programming Windows 5th Edition.

I have learned how to make a dialog box like this:

#include "windows.h"

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLind, int iComdShow)
{
	MessageBox (NULL, TEXT ("Hello World!"), TEXT ("HelloMsg"), 0);
	return 0;
}

But, I would like to control the size of the dialog box.

Thank you!

I don't think that you can resize the MessageBox. It resizes automatically to the text/buttons. You might want to create your own DialogBox instead.

Unfortunately, MessageBox has it's own ideas.

Why doesn't my MessageBox wrap at the right location?

If you want to control the size, you'll need to code your own dialog (or ever custom messagebox), as ats15 has already said.

I will try making a DialogBox instead.

I haven't looked at the second one yet, but the first one looks interesting.

Thank you!
