The type or namespace name 'Windows' does not exist in the namespace 'System' (are you missing an assembly reference?) C:\Documents and Settings\adirim\My Documents\Visual Studio 2005\Projects\project\ClassLibrary1\Class1.cs 4 14 ClassLibrary1
What is the problem ?
Thanks.

You are missing a reference to the System.Windows.Forms.dll
In order to use the System.Windows.Forms namespace and classes in your code your project must reference the dll library in which those classes are compiled. When you create a windows application project this reference is included automatically by Visual Studio. When creating a class library you have to be explicit.
In the solution explorer right click the references folder below your class library project, select add reference. In the NET tab scroll down to System.Windows.Forms.dll and select it and click ok, now the using statement will be valid and the project should compile.
