Something very strange happened here in Visual Studio 2008 (C#).
After deleting an icon resource from my project all my menu items and toolbar buttons disappeared. I checked my form Designer.cs file and the code to the items are still there. Also, I tried to search for the deleted resource file name (warning.ico) in the entire solution, and nothing was found.
What happened and how can I fix this?
Just discovered.
Somehow, Visual Studio messed the Designer.cs file of my form. After close inspection, the AddRange Method of my menu and toolbar was missing.
Just fixed manually by adding:
this.mainToolbar.Items.AddRange(new System.Windows.Forms.ToolStripItem[] { this.lsbPort });
