I dont know where to put the question. But I m kind of bugged so I am putting it here. I am a Major In Metallurgy and Material Science but interested in excel. I need help on a particular topic.
I have made a userform in excel which has 1 combobox and 5 textboxes.
i have source data as an excel sheet in the same workbook.
I initialized the userform to display all values of my combobox which is in the 1st column
Now if I select a particular value from the dropdown list of the combobox I want the textbox fields to be automatically filled by their corresponding values in the spreadsheet. How to do this. Please Help???
Thanking in Advance

Something else I noticed (just a error handling piece), how do you handle the run-time error you get when you click the windows close button instead of the form close button.

(I get this funky "callee, not server callee, may have been executed, blah blah, etc etc" message).

Re parent/child: I think the class modules will be easy since they're naturally encapsulated. But filling the classes presents the problem. I can definitely create code that gets an Employees instance as an argument and fill a Paychecks class for that employee, but from where would I call that sub? Would I modify the FillEmployeesClass to call FillPaychecksClass(clsEmployee as CEmployee)? That's seems tougher particularly since the user could have modified FillEmployeesClass and I wouldn't be sure just where everything is. I could just not call it and leave that step to the user. Or I could create the call code, put it outside of a module for the user to cut and paste into the proper place. I need to do just enough to make this useful without going overboard.

Keep the suggestions coming.

Again, thinking out loud, specifically about the parent/child class thing, I'm guessing you'd need to read the available classes of whatever your target VBE Project is (or will be) and, chose one (via combobox, maybe?), then, if you choose to make that a child of the selected parent, then you'd have to do a few additional steps:
1. insert the child into the parent class
2. (and this one would be optional, but handy) set up the parent pointer

Also, looking through your example, what would be a great side-project to this one (ha, ha) would be to create the same kind of framework but for user forms (since they're really just class objects, after a fact). But just thinking about how to go about that makes my head want to explode.

But, you'd have one killer VBA Framework/Project Builder!

Something else that came to mind this morning that would make it even more dynamic is to have an additional field at the top of the form where you can browse for the MDB you're looking for using GetOpenFilename. That way you don't have to hardcode the path and filename.

Just thinking out loud, really.

Good one on the read-only, Scott. I think I’ll also let the user choose the VBProject from a dropdown rather than write to the activeworkbook. I really want to make the Paychecks class a child of the Employee class, but I’m not sure the best way to implement it yet.

Love it. Love it love it LOVE IT. I took the original code from the "Create Classes" post and started using it immediately because I found it just so very useful. But this is great stuff! It takes so much of the grunt work out of it for you.

I'm afraid I can't offer any huge suggestions about what to add or keep at this point. You might want to let users chose whether the fields they're selecting for classes are read-only or read-write (that's all I've got off the top of my head), but whatever the additions, I can't wait to see the next iteration of this thing.

The Payroll.mdb file was not included. Only the Payroll.idb locking file. Oops
