Autoexpand a combo box

[jamesd0142]

comboboxname = cboln03

Is it possible to click a button and the combo box expand as if a user clicked the arrow?

so click a button - cboln03 opens to reveal list of items.

Thanks

You could try this (little sample I just wrote and tested - it appears to work)
[CODE=vb]Combo1.SetFocus
SendKeys "{F4}"[/CODE]

Hi Killer42

Can you explain to us what's the function of using F4? I really have no idea. LOL

[Killer42]

When the focus is on a combobox, you can press the F4 key (also Alt-Down, I think) to expand the list.

Thanks thats what i needed!

could you use this sendkeys thingy to capture key press?

say something like:
[code=vbnet]
if sendkeys.send(" {alt+a}") = true then
'do something
end if
[/code]

I'm not familiar with the capabilities of VB.Net (I use the ten-year-old VB6) but as far as I know SendKeys is only for sending, not receiving.

SendKeys does not allow for the processing of keys inputted, however it is possible to detect keyboard actions using keydown/keypress events on different objects. The example below demonstrates how.

[CODE=vbnet]Private Sub textBox1_KeyDow n(sender As Object, e As System.Windows. Forms.KeyEventA rgs) Handles textBox1.KeyDow n

If e.KeyCode == 65 Then
' Whatever you wish to do, note you can convert the key code to its ASCII char
End If

End Sub[/CODE]

I hope this helps you with getting key input. Each character has its own decimal value and I'm not sure but I believe you can use Chr() to convert its decimal value into the ASCII character.
