How to change the default Icon of a win Form and including it in the .exe file?

Question

Dear All I am new programming in c# the first programs I am developing are not too big and I am developing them by hand it means I am not using the VS wizzards. I compile the applications (console or winapp) from the command line. My problem is that I don't know how to change the default Icon of a Form and including it in the exe file. I mean I know that I have to use : this.Icon = new Icon(myicon.ico); to assign the Icon. The application works if I have the file myicon.ico in the same directory as the application but if I try to execute the application in another directory it crashes because it doesn't find the icon file it produces a portability problem I have already try with other code like: Icon icon1 = (System.Drawing.Icon)this.FormResources.GetObject(myicon.ico); or Stream strm = (Stream) Assembly.GetExecutingAssembly().GetManifestResourceStream(myicon.ico); this.Icon = new Icon(strm); and always I get the same problem or a worse one. what ever now I am lost in a cycle and I ask for your help may be the solution is not so complicated but I would appreciate the replies and if someone help me to solve the problem. thank you very much in advance desperate Oriana

You need to add your icon file to the project Resources. Then the icon will appear to be myIcon. Your can change your code to this.Icon = Properties.Resources.myIcon;

Hi Roei thanks a lot for your Reply I tried also that code it assigns a new Icon to the .exe file. But what I mean is the default windows icon on the top of the window at the left corner. I defined the form property with: this.Icon = new Icon(myIcon.ico); and I can see the Icon in the right position in the form but If I copy the .exe file in other location the application crashes because it doesn't find the Icon file it means that I have to copy the Icon in the same directory as the .exe file. But I can not request every user of my application to copy both files. the .exe and the .ico I think there is a better way to compile the Icon togehter with the application to include it in the .exe unfortunately I haven't found the right bibliografy to do it I hope you or someone of the forum can help me to solve this problem. thank you very much in advance: Oriana

dude on the form properties you have a property called ICON just select your icon and thats it and if you want to compile via Command line add this /win32icon: .cs
