Hi, How programmatically expand COMBO? POST(EVENT: what???, ?COMBO1) SELECT (?COMBO1); PRESS (CtrlDown) ! Not work :frowning: Michael

MODULE('') PostMessage(UNSIGNED hWnd,UNSIGNED wMsg,UNSIGNED wParam,| LONG lParam),BOOL,PASCAL,NAME('PostMessageA'),PROC END ShowDropDown PROCEDURE(LONG pFEQ) fCB LONG hCB LONG CB_SHOWDROPDOWN EQUATE(014Fh) CODE fCB = pFEQ{PROP:ButtonFeq} hCB = fCB{PROP:Handle} P…

This API call does it for me: See Post #11 for revised CODE [image] Is a COMBO List Dropped? I think in my testing I had arrowed down to a selection so it showed in the Entry, then I typed another value and the list remained dropped, then I tabbed out with…

Thanks, it works! :slight_smile: I combined both tips into something like this (and MAP PostMessage) ShowDropDown PROCEDURE (LONG pFEQ, BYTE RollUp = 0) fCB LONG CB_SHOWDROPDOWN EQUATE (014Fh) CODE fCB = pFEQ {PROP: ButtonFeq} PostMessage (fCB {PROP: Handle}, CB_SHOWDROPDOWN, 1-RollUp, 0)

Michael, I am curious as to when/what user input within a procedure prompts the need to drop down a combo? Douglas

@totalhip , Filter button also serves (next click) as a quick view / change of the current filtering - at the same time there will be no reports that filtering is not working - 2 in 1 :wink: Michael

If I understand correctly - a click of the filter button resets the view AND drops the combo?

@totalhip This button starts filtering, but another press without changing the conditions doesn’t change the view, so now it shows the list of combinations right away - to show what you can switch to (combo not the only filter, there are other filters checkbox). And another button clears the filte…

Just looking for ideas as to when forcing a combo drop might be useful. In my derived combo class, queue loading does not occur until x# of keys have been entered. There is also an option to do a LIKE sql select instead of an alpha select. Forcing a drop for LIKE might be very useful.

Just tested and definitely not recommended for use with AnyScreen.

My code from post #3 was missing COMBO support, your code does not handle LIST. Below code handles both Drop LIST and Drop COMBO: MAP ListDropDown PROCEDURE(LONG FeqList, BOOL RollUp=0) !0=Down 1=Up MODULE('Win32') PostMessage(LONG hWnd,LONG wMsg,LONG wParam,LONG lParam),BOOL,PROC,…

Programmatically expand COMBO to show drop down list?
