Why does my icon not appear in the title bar?

Question

I have assigned an icon to my application from the Properties window in Solution Explorer in Visual Studio; the application's icon changed successfully but the title bar is still showing the default icon:

I've rebuilt my application but it still displays the default icon. What am I doing wrong?

Answer 1

Because forms have a different icaon configuration than the application. Set the icon on the form, not ONLY on the application.

Answer 2

There is another reason why the icon might not show.

If the ControlBox property of the Form is set to False the icon will not show.

(Sounds like an undesired side effect)

Answer 3

I know that it is a very old issue but I can add the following comment :

Pay attention to the 'FormBorderStyle' property. If 'FixedToolWindow' or 'SizableToolWindow' are selected, your icon will not appear, even if you specified an icon in the 'Icon' property. I encountered the same issue. Good luck.
