The Visual Basic "Button" class lets you create a control on your VB projects that perform an action such as auto-save. VB also includes file classes that help you create functions to save files.

I wrote a program that generates fractals in visual basic. The way it currently works is that I pass the function a handle to a device context and it uses SetPixel to draw to that hDC.

Click the "Save" icon on the VB6 toolbar to save the code. Close the code editor window for the command button. Press the "F5" key to launch the application and display a live version of the form.
