AV on multipage chart print

GL123 · Post by **GL123** » Mon Jan 14, 2008 4:03 pm

I'm getting an AV when I attempt to print a multi page chart. My code just calls the ChartPreview function and the AV happens after OK on the select printer dialog.

I tried the feature in the demo app (Tee8New) and it also bombed. Is this a known problem or am I missing something ?

Delphi 7 + Teechart Pro 8.01.10798

Hi GL123,

Could you please try if including OpenGL unit as described on this thread solves the problem at your end?

If it doesn't, would you be so kind to send us a simple example project we can run "as-is" to reproduce the problem here?

You can either post your files at news://www.steema.net/steema.public.attachments newsgroup or at our upload page.

Thanks in advance.

Thanks. I tried adding the OpenGL unit but no luck.

I've uploaded a simple test app on the upload page. TeeChartTestApp.zip.

Thanks. Can you suggest any sort of workaround before then? I need to release my software on Monday and this has just been raised as an issue

Try draw your charts onto Printer's canvas.
This code draws two charts side by side below the mid of the page

Code: Select all

var
  PX, PY, OrgY, OrgX : Integer;
  R: TRect;
  MetaF : tMetaFile;
begin
  PX:=Printer.PageWidth div 100;
  PY:=Printer.PageHeight div 100;
  OrgX:=PX*8;
  OrgY:=PY*6;

  YourChart1.Printing:=True;
  MetaF:=YourChart1.TeeCreateMetafile(True,Rect(0,0,313,217));
  R:=Rect(OrgX,PY*50,PX*49,PY* 70);
  _Canvas.StretchDraw(R,MetaF);
  MetaF.Free;
  YourChart1.Printing:=False;

  YourChart2.Printing:=True;
  MetaF:=YourChart2.TeeCreateMetafile(True,Rect(0,0,313,217));
  R:=Rect(PX*57,Py*50,PX*98,PY* 70);
  _Canvas.StretchDraw(R,MetaF);
  MetaF.Free;
  YourChart2.Printing:=False;

Hi GL123,

We've tested this issue with the actual sources and we aren't able to reproduce this problem. Could you please try if the latest version available to download (v8.04) solves this for you?
