Using Drawing Methods From DLL

Question:
I wanted to create a front end GUI panel using VB. This panel would have command buttons, and a picture box. When the user clicks on a command button, I want to call a DLL to draw lines and polygons in the picture box. The DLL will be written in Visual C++. Can I do this?

Answer:
All controls in VB have the hWnd property, and some have the hDC property. That can be passed into a DLL so that you can draw on it. Other than that hook, you do not need anything else from VB, except for making sure that you are using the correct call to your DLL function.
