/win32icon (Import an .ico File)



The .ico file that you want to add to your output file.


The /win32icon option inserts an .ico file in the output file, which gives the output file the desired appearance in the Windows Explorer. An .ico file can be created with the Resource Compiler. The Resource Compiler is invoked when you compile a Visual C++ program; an .ico file is created from the .rc file.

See /linkresource (to reference) or /resource (to attach) a .NET Framework resource file. See /win32res to import a .res file.

To set this compiler option in the Visual Studio development environment

  1. Open the project's Property Pages dialog box. For details, see Setting Visual C# Project Properties.
  2. Click the Common Properties folder.
  3. Click the General property page.
  4. Modify the Application Icon property.

To set this compiler option programmatically

See ApplicationIcon Property.


Compile in.cs and attach an .ico file rf.ico to produce in.exe:
