CB_SETMINVISIBLE will do the trick. Default is 30 items, we test 10 and 50 here:

Code: Select all

OpenWindow(0,0,0,800,600,"",#PB_Window_SystemMenu|#PB_Window_ScreenCentered)
ComboBoxGadget(0,20,5,200,20)
For i=0 To 99
  AddGadgetItem(0, -1, "Item "+Str(i))
Next

SendMessage_(GadgetID(0), #CB_SETMINVISIBLE,10,0)

ComboBoxGadget(1,250,5,200,20)
For i=0 To 99
  AddGadgetItem(1, -1, "Item "+Str(i))
Next

SendMessage_(GadgetID(1), #CB_SETMINVISIBLE,50,0)

Repeat:Until WaitWindowEvent()=#PB_Event_CloseWindow

I just tried the code you submit and works correct here KCC, what system are you using, I am on win7, I will try win8.1 later and see if that ok.

Me too i have w7...
For me the 3 combo have the same height and the same number of items

[netmaestro]

The same number of visible items, is that right? All combos have 100 items but the size of the dropdown should be different and show different numbers of items before the scrollbar appears.

Hello Netmaestro,

It's that i don't understand.
I have open each combo one by one (obviously) and the height of each combos open have 23 items if my memory is good (i can't test again i'm on my android tel)
I have even modify your number and no effect
Why kcc never be like the others ?
