Freeing Graph.

rbuser

Hi,

I'm previewing a Report with graph in it. I can preview the report first
time, but if I try to preview the graph again its shows access violation
while loading the file to the ppReport component. If this because the graph
is not freed from the memory ?

How will I free up a graph ? The line ppReport.LoadfromFile raises the
access violation while loading a report with graph.

I'm using Report Builder 6.03 Professional demo version for delphi 4.

Thanks

What does your code look like?

Hi,

I have added the code below.

if not (dbCurrentDatabase.Connected) then
dbCurrentDatabase.connected := True;

if not (dbGlobalDatabase.Connected) then
dbGlobalDatabase.connected := True;

//ppDesigner.AllowDataSettingsChange := TRUE;
//ppDesigner.DataSettings.AllowEditSQL := TRUE;
ppReport.Template.New;
ppReport.Template.FileName :=
'C:\Absence_Analysis_by_Year_with_Graph.RTM';
ppReport.Template.Loadfromfile;
ppReport.Print;
end;

You don't have to call Template.New before loading a template. You can just
load a template form file and you're good to go.

Make sure that the Designer.Report property is assigned.

Other than that it should work. I see that you are using RB 6.03 demo
version. If you aren't using Delphi 4, then download our latest: RB 7 which
works with Delphi 5, 6 and 7. www.digital-metaphors.com

If you still are having trouble, then send us a simple report project that
doesn't work and we'll run it to see what is causing the problem. Send all
attachments to support@digital-metaphors.com
