An AV occurs when destroying a TdxGPImage object whose image was loaded from a file or stream and immediately after that was resized via a TdxGPImage.Resize method call

created 12 years ago

Hi,

i'm using tdxTilecontrol and create my item with following code:

try tctilecontrol.BeginUpdate;
while not mydataset.Eof do begin
AItem := tctilecontrol.createItem(true); AItem.Glyph.Image.LoadFromFieldValue(mydataset.FieldByName('PHOTO').Value);; AItem.Glyph.Align := oaMiddleRight; AItem.Glyph.Image.resize(60, 60); AItem.Tag := StrToInt(mydataset.FieldByName('TA_PER_ID').AsString); AItem.Style.Font.Size := 10; AItem.Style.Font.Color := clBlack; AItem.Text1.Value := mydataset.FieldByName('NAM').AsString + ' ' + mydataset.FieldByName('FSTNAM').AsString; AItem.Text1.IndentHorz := 5; AItem.Text1.IndentVert := 10; AItem.Text2.Value := mydataset.FieldByName('PHNB').AsString; AItem.Text2.Align := oaTopLeft; AItem.Text2.IndentHorz := 10; AItem.Text2.IndentVert := 30; AItem.IsLarge := true; AItem.Style.GradientBeginColor := RGB(242, 199, 119); AItem.Style.GradientEndColor := RGB(242, 199, 119); AItem.OnClick := OnItemClick; aPer.Next; end; finally tctilecontrol.EndUpdate; end;

procedure TfrExposes.OnItemClick(Sender: TdxTileControlItem);begin tePersonne.Properties.OnChange := nil; try label.Text := Sender.Text1.Value; finally tePersonne.Properties.OnChange := tePersonnePropertiesChange; end;end;

To clear the tdxtilecontrol i m using:

tcxtilecontrol.BeginUpdate(); try for I := pred(tcxtilecontrol.Items.Count) downto 0 do begin tcxtilecontrol.Items.Delete(I); end; finally tcxtilecontrol.EndUpdate(); end;
And i got a violation acces error.
This error is due to the resize procedure (when i comment it, it works)

Thx for your help
