I have no clue why I am getting this error when I try to run the program. I
make absolutely no reference to PrintMargins.

Anyone have any idea?

Hi Gord
I think your application is being compiled using an old version of TeeChart
(check your "Search Path"), and this old version cannot recognize the
PrintMargins property as it is new in version 7.

PrintMargins custom values should be inside the *.dfm form file.
They get persisted whenever a change in the Print Preview dialog is done
to margins.

You can try switching to Form Text mode at design-time (pressing Alt+F12),
then manually deleting the PrintMargins values and Alt+F12 again.

David,

Thanks for your reply. However, I am not getting anywhere and am pretty
frustrated.

I haven't done anything unusual that I can see. I installed TeeChart7
without changing any of the defaults. The installation seemed to have moved
the original TeeChart files (v4) to a backup directory which makes sense.

I have checked my search paths. For the Compiler they are as follows:
$(BDS)\include
$(BDS)\include\dinkumware
$(BDS)\include\vcl
...\..\..\..\program files\steema software\teechart standard 7 for delphi
2006\delphi10\include

For the Linker they are as follows:
$(BDS)\lib
$(BDS)\lib\obj
$(BDS)\lib\psdk
...\..\..\..\program files\steema software\teechart standard 7 for delphi
2006\delphi10\lib
...\..\..\..\program files\steema software\teechart standard 7 for delphi
2006\delphi10\lib\obj

I looked at the install packages and it had a check beside TeeChart 7
Standard Components
Build with Runtime Packages was checked. tee, teeui, and teedb were listed
in there.

For the life of me, I cannot see where it would be using an old version of
TeeChart.

Next, you are right, PrintMargins is in the *.dfm file. I didn't delete it
because if it is part of TeeChart7, then it should be able to stay there,
the problem is obviously elsewhere. But for some strange reason I don't
actually see a PrintMargins property on the Object inspector which makes me
suspicious.

So then, I tried a brand new project. I added a TChart component. This
time I never clicked on it at design time. I did a project build and ran
it. A form appeared successfully (no error as shown in the Subject line
above) and a blank chart was on the form. Success - to a small degree.

I added one button to the form and put the following code inside the button
click:
void __fastcall TForm1::Button1Click(TObject *Sender)
{
Chart1->BottomAxis->Title->Caption = "This is the bottom title";
}
It built fine, but when I clicked on the button, I got an exception with an
EAccessViolation. Arg.

So I abondoned that and tried to add a series and some data. I borrowed
some code of yours that you posted earlier in this newsgroup just to see if
I could add a series.
void __fastcall TForm1::Button1Click(TObject *Sender)
{
Line1=new TLineSeries(this);
Line1->ParentChart=Chart1;
// Chart1->BottomAxis->Title->Caption = "This is the bottom title";
}

I do a build and get the following three errors.
[C++ Error] Unit1.cpp(19): E2451 Undefined symbol 'Line1'
[C++ Error] Unit1.cpp(19): E2303 Type name expected
[C++ Error] Unit1.cpp(19): E2379 Statement missing ;

In case you were wondering, unit1.h does contain
#include <Classes.hpp>
#include <Controls.hpp>
#include <StdCtrls.hpp>
#include <Forms.hpp>
#include <Chart.hpp>
#include <ExtCtrls.hpp>
#include <TeEngine.hpp>
#include <TeeProcs.hpp>

Help!

BTW, if I do use TeeChart, almost all of the interaction will be coded as
opposed to doing things at design time, which is why I am trying to see if I
can do the most basic of things right now (such as adding a bottom title, or
adding a series).
