I need help!!!! Is there anyway to do subforms in VB like you can in access.... What I need a subform for is say I enter a Container Number in a text box named txtNum i need that number from that text box to automatically go into the subform textbox txtNum so i can link them together.... The main form will be used for cantainer information (stored in tbl_sampleInfo in access) and the subform will be used to put test results (tbl_testResults in access) for that container.

Have a look at THIS link. It contains several interactions with multiple forms in your project.:)
