Hello Ken,
For what you're doing, try this:
Stream strm = Assembly.GetExecutingAssembly().GetManifestResourceStream("TestIcons.App.ico");
this.Icon = new Icon(strm);
-- Matt Berther http://www.mattberther.com > OK, so I set the build action on the ICON file as indicated. I then > entered the following two lines of code in the constructor for my > form: > > Stream strm = > Assembly.GetExecutingAssembly().GetManifestResourceStream(typeof(Image > ), > "TestIcons.TestIcons.App.ico"); > this.Icon = Image.FromStream(strm); > Where "TestIcons" is the name of the solution and the project. When I > attempt to compile, I get the following error: > > Cannot implicitly convert type 'System.Drawing.Image' to > 'System.Drawing.Icon' > > It is odd that I am loading an "Image" resource when it is really an > "Icon", but the Icon class does not have a FromStream() method.
