This example implements a class in Visual Basic .NET or Visual C# that can take a Measurement Studio 6.0 CWGraph object and print it in. The CWGraph controls exports a ControlImage() method that returns a System.Drawing.Image object. ControlImage() returns a metafile, and the wrapper class, which is created automatically by Visual Studio .NET, returns a .NET image. As a result, you can use a PrintDocument object to print the graph image.
When using any ActiveX controls in Visual Studio .NET, keep the following differences in mind:
1.) Visual Studio .NET generates a Runtime Callable Wrapper (RCW) around each control, and you must go through the Interop layer to use the controls. As a result, some class names differ from the names in Visual Basic 6.0.
2.) Hosting an ActiveX control in Visual Studio .NET requires unmanaged code permissions.
3.) Hosting an ActiveX control in a Windows Form increases the size of your project files because the entire control is embedded in the form.
For more information about using ActiveX controls in Visual Studio .NET, refer to the Visual Studio .NET help.
