Combobox : No vertical scrollbar!

[Frederic Faure]

Hi,

I'm just beginning with DDT, so it could be sthing ez, but the combobox below displays no vertical scrollbar when I click on the arrow even though not all items can be shown. Is it an extra setting that is not listed in the help file?

    DIM MyStrings(7) AS STRING
    MyStrings(0) = "Machine 1"
    MyStrings(1) = "W2K"
    MyStrings(2) = "Machine 3"
    MyStrings(3) = "Machine 4"
    MyStrings(4) = "Machine 5"
    MyStrings(5) = "Machine 6"
    MyStrings(6) = "Machine 7"

  CONTROL ADD COMBOBOX, hDlg, %IDCOMBO, MyStrings(), _
    27,  9, 197, 39, %CBS_DROPDOWNLIST OR %CBS_SORT OR _
    %CBS_UPPERCASE OR %WS_TABSTOP

Thx
FF.

Add %WS_VSCROLL to the style list. However, if the height of the CB is too low, you may not get a scroll thumb.

Also try adding %CBS_DISABLENOSCROLL if you always want the scrollbar even if the list is less than the combo's dropdown height.

Thanks Lance, that did it.

BTW, that switch was not mentionned in the ADD CONTROL COMBOBOX section in the PB/DLL 6 help file.

Thx

Yes, but the next one is very likely to!

The main thing to remember with DDT controls is that you can use almost any style that a conventional Windows control can use, so WIN32.HLP can still be very valuable for additional Windows-related information not covered in the PowerBASIC documentation.

If you have no done so, you can download the WIN32.HLP file from http://www.powerbasic.com/files/pub/mstools/win32.zip

Also keep you eye on the latest WIN32API.INC file set from http://www.powerbasic.com/files/pub/pbwin/win32api.zip (this one is updated on a fairly regular basis).

I hope this helps!
