check if a control is hidden or not
Posted: Mon Sep 24, 2018 08:15 AM

Could someone please tell me how to detect a hidden control?

I've tried:

REDEFINE BUTTONBMP ID 505 OF oFld:aDialogs[3] ;   //show images
         ACTION ( msgstop( GetNMHDRHWndFrom( oBmp[3]:oDlg ) ), ;
         Show_Hide_Img(.F., .T., oDbf, oDlg, @oBmp, @cText, aPedg, cImages) );
         BITMAP ".\images\camera.bmp" 
REDEFINE IMAGE oBmp[3]   ID 400 OF oFld:aDialogs[3] ADJUST UPDATE

msgstop( IsWindowVisible( oBmp[3]:oDlg ) )
msgstop( IsWindowVisible( ::oBmp[3]:oDlg ) )
msgstop( IsWindowVisible( oBmp[3]:oDlg:hWnd ) )
msgstop( IsWindowVisible( ::oBmp[3]:oDlg:hWnd ) )

msgstop( IsWindowVisible( oDlg:hWnd ) )  //<-- this works but I do not need to know if the dialog is hidden, but if the control oBmp [3] of the dialog oDlg has been hidden

I get "Error BASE/1004 Message not found: TIMAGE:ODLG"

Since this was urgent I solve it like this:

Code (fw): Select all Collapse

LOCAL lHide:=.F.
...
REDEFINE BUTTONBMP ID 505 OF oFld:aDialogs[3] ;   //show images
         ACTION ( lHide:= !lHide, ;
         Show_Hide_Img(lHide, .T., oDbf, oDlg, @oBmp, @cText, aPedg, cImages) );
         BITMAP ".\images\camera.bmp"
REDEFINE IMAGE oBmp[3]   ID 400 OF oFld:aDialogs[3] ADJUST UPDATE
...

But it will be nice to know the "right" way

Thanks
