Changing Form's Icon in Visual Studio 2012 C#

Question

I am trying to change the icon of the form (top left) and any other place I see little squares default icon.

I have tried:

• Clicking the form, go to "Window Style" and changing the Icon to the .ico file I have on my computer - this shows as if it actually changes - but whenever I debug or publish - it is still the original default Icon.
• Going to Project's properties- Resources - adding the Icon as Resource - back to Application under Properties - change "Icon and Manifest" to the resourced Icon. It shows the new Icon next to the browse button - but nothing changes in the actual program.

Note at first the Background Image I had selected for the form wasn't applying either - I would change it via the form - Properties - Appearance - BackgroundImage - Select from computer. Would show as changed but as soon as I would debug or publish or would not be there. -Added it to my resources and then chose it from the BackgroundImage browse - chose it from project resources and then it worked.

Answer 1

Found a solution: With the idea that my Background image wasn't working until I had it in the Resources. I went to the Form1_load event and added the following code:

System.Drawing.Icon ico = Properties.Resources.Untitled;
this.Icon = ico;

As "Properties.Resources.Untitled" being my icon that I added to my Resources.

And now seems to be workings as wanted.

Answer 2

You need to change the icon on every form as well using the Icon property of the Form.
