Apply changes to mainforms Form.Icon at runtime

Question

I have a System.Windows.Forms.Form and want to change the Form.Icon at runtime to display a status. I\'ve managed to load the icon from the projects ressources:

Answer 1

I Guess, first of all, your GetObject(...) is returning null. Thats the reason the type casting is ending up silently neither throwing error nor change the icon.

Instead,if possible, use

this.Icon = new System.Drawing.Icon(...) 

overloads and then give a try.
