[BUG/PRB.] VFP 9.0 FIX - THE SELECTED REPORT OBJECTS ARE PRINTED WITH SHADOW
January 2024
--------------------------------------------------------------------------------------
CCB
1. BUG:
In vfp9, if we select some report objects and save the report file, it will set the CURPOS field to true (.T.) for the selected report objects.
When we run the report in the preview window, the selected report objects are printed with shadow.
The bug only occurs in vfp9, it does not occur in vfp6, vfp7 and vfp8.
The bug only occurs when set ReportBehavior 80, it does not occur when set ReportBehavior 90.
In vfp9, it will show some shadow in the preview window, please refer to the picture testshadow0-vfp9.jpg:
and then, it will show the report in the preview window, please refer to the picture testshadow-vfp9.jpg:
2. CAUSE:
There are some BUGs in the following code.
3. RESOLUTION:
We can write some code to fix the BUG.
Fun48f7f6 :: ; proc near
push ebp ;0x0048f7f6 : 55
mov ebp , esp ;0x0048f7f7 : 8bec
sub esp , 013Ch ;0x0048f7f9 : 81ec3c010000
mov eax , dword ptr [ Data937090 ] ;0x0048f7ff : a190709300
mov dword ptr [ ebp - 4 ] , eax ;0x0048f804 : 8945fc
pushd 043h ;0x0048f807 : 6a43
lea ecx , dword ptr [ ebp + 0FFFFFEC8h ] ;0x0048f809 : 8d8dc8feffff
call Fun43c868 ;0x0048f80f : e854d0faff

;
; In vfp9, if we select some report objects and save the report file, it will set the CURPOS field to true (.T.) for the selected report objects.
; When we run the report in the preview window, the selected report objects are printed with shadow.
; In VFP Advanced, it will ALWAYS use the CURPOS field as false (.F.), so there is no the shadow in the preview window.

Now in VFP Advanced, it will ALWAYS use the CURPOS field as false (.F.), so there is no the shadow in the preview window.
