D2006 VCL .NET Object reference not set to instance....
Posted: Thu Jun 29, 2006 9:28 am
D 2006 VCL for .NET (update 2)
TeeChartPro V7.07 Delphi 2006
We're getting an immediate
"Object reference not set to an instance of an object."
When trying to use TChart. (version as above)
Easy to re-create:-
1) Drop a TChart & a Button on a VCL for .NET Form
2) Add this code to the onClick of the button:(from the help docs)
procedure TForm2.Button1Click(Sender: TObject);
var tmpLineSeries:TLineSeries;
begin
tmpLineSeries:=TLineSeries.Create(self);
Chart1.AddSeries(tmpLineSeries);
tmpLineSeries.FillSampleValues(10);
end;
Make sure your "Uses" includes these " TeeProcs, Chart, Series"
Run the app but dont click the button just yet.
a) Now left & right click on the blank TChart - No problems
b) Now click the button to populate the Series, NOW TRY to click the
left or right buttons - IMMEDIATE "Object reference not set to an instance of an object." ERROR!!!!
HELP!!
I can email the entire source, with PDB if required.
Thanks in advance - We're stuck without this folks...
