This sample, completely rewritten from an original sample at this site
by Mark Grimes (firstname.lastname@example.org),
demonstrates how to create a full VB-style Open project dialog
by taking advantage of the Hook support provided in the
CommonDialog/Direct DLL component.
Implementing a hook for a Common Dialog allows numerous messages in the dialog to be intercepted.
In this case, the dialog open notification is utilised to capture elements from a VB form into the
common dialog, and OK/Cancel button clicks are intercepted to determine whether to close the VB form.
The result is an excellent way of creating customised File Open dialogs which additionally show your
There is another way to implement this sort of functionality, which is to use Common Dialog Templates. Cayce
Cochran rose to the challenge of making templates work in VB, and you can see the result in
the sample Common Dialog Templates. Excellent stuff, but the approach
only supports the standard Windows controls. If you need something more, then hooking the dialog and
combining it with a VB form is the way to go.
The only difficulty with it is that the coding to get all the items in the right place, and working
out the tabbing, can be pretty tedious and error prone. Since the only way to ensure tabbing works
correctly is to use a Windows Keyboard Hook, you also might find
it difficult to debug...
