I installed OQB on delphi6. I compiled the bde demo and run it.
When I try to select a field from a table to be include in the sql statement
I get an AV at the line below. ( see ***** AV: HERE *******)
procedure TOQBLbx.ClickCheck;
var
iCol: Integer;
begin
inherited;
if FLoading then
Exit;
if Checked[ItemIndex] then
begin
TOQBForm(GetParentForm(Self)).QBGrid.Insert( // ***** AV: HERE *******
TOQBForm(GetParentForm(Self)).QBGrid.ColCount,
Items[ItemIndex], TOQBTable(Parent).FTableName);
end
Full Version: AV: when selecting a field
Thank you for bug report.

Yes, all the time I try to add a field
Hi, I have found the same error with OQB in Delphi 6. The problem seems to be that the parent of the stringGrid (TOQBGrid) is being set as nil. For some reason the parent property of (tabColumn - TOQBgrids parent) is being set as nil in delphi 6. The same code recompiles and runs ok in delphi 5.anyone got any ideas ?
Thankx in advance.

Just want to confirm the I'm having the same problem in D6. D7 is OK.
Anyone working on a fix?
I notice that after dropping in my much hacked Qbuilder.pas, which dates back to the days of Delphi 4, no such problem.
I've just placed an update at http://groups.yahoo.com/group/fastreport/f...51_MSAccess.zip
Be warned that this thing is very muched geared towards MS-Access, ie unsual table and field name delimiters, although you can easily change that be searching for
FmsAccess := True;
and changing it to
FmsAccess := False;
TIA
A very simple fix is add this line:
QBGrid.Parent := TabColumns;
in the event OnCreate of OQBForm
The problem is that TOQBForm.CreateParams if called before TabColumns is loaded. A professional fix is create a procedure Loaded in TOQBForm class which is called automatically after OQBForm is fully created. But is similar to my first fix.
QBGrid.Parent := TabColumns;
in the event OnCreate of OQBForm
