What is the best way to pass a string from one form to another? I have multiple instances of a main form which allows a user to select multiple users for a query.

For layout purposes... Rather than putting the user listbox on the main form, I have a Select User (frmSelUser) form opened with the user listbox.

I would like to pass the calling formname to frmSelUser so that I know which form to pass the string of selected users back to... since there can be multiple instances of the form opened at one point in time.

Thanks!
