Capturing a screen shot without using clipboard

I am trying to capture a screenshot and saving it in a file without using Clipboard and no forms are created. I just wanna to write a function, so that on calling that function it should perform the action. Is there any method of doing this without using Clipboard and Forms like PictureBox, EditBox ,etc.. I am working on a Test Automation tool which has VBA language, but doesn't support Clipboard objects. Please help me and suggest me the code to capture a screenshot. Your help will be highly appreciated!! Thanks.
