when using a combo box to look up some info on a form the code builder pops up titled Microsoft Visual Basic and in the pop up it says....Compile Error: Cant find project or Library
On code builder it has highlighted in yellow private sub combo38_AfterUpdate
It looks to me you just copied the source code of an application from another computer to another one. When you do that, remember also to copy your VB setup from where it was original designed. Check the Project - Reference and Components set up. YOu're missing something, a component or referencing dll's.
