Hi

I need to make a combo box open upwards rather than downwards, like when they are towards the bottom of the screen.

Anyone know how to do this?

Thanks.

Create a textbox.
Put a command button on its side.
Place an invisible listbox above it.
When user clicks on the command button the listbox should show up.

Just a Q: Why to move outside standards?, it only confuses end users.

I was a user who asked for this!  It baffles me, but what to do?

Thanks for the ideas, but I have had to fudge my form enough by being forced to use flex grid and I am looking for maybe an api call on the combo.  If it cannot be done, then the user will have to stick with "normal" methods!

Well, i haven't vb installed so i cannot test it but this would be my first approach:
1) subclass combo box to intercept
Const CB_SHOWDROPDOWN = &H14F
message
2) Create a hidden list box attached to combo box trying to emulate the drop section of combo
To do this, see:
http://www.mvps.org/vbnet/code/listapi/listcopy.htm
3) Show/hide that list box that should be stay above combo box .Top porperty, taking care that they would not be overlapped each other.

In other words, cheat the combo and too much work for, IMHO,  a not useful feature.
Cheers

I will accept your answer, but Im not using the code.  Ive already got a class module with about 1000 lines of code in it to pop up combo's and text boxes on a flex grid and do validation etc and that has been a nightmare to get 100% right in product and uat testing.

The user can stick with good old fashioned drop downs!

Thanks anyway.
