I get the following if I try to access the form's clientwidth or height:

frmmain_fmmain.tcontainercontrol_fclientwidth is null or not an object

By the way, it's really annoying that I can't cut and paste from the error dialog.

Eric,

When/where are you trying to access the client width ?  If I try it here in
a button click handler, it works fine.

<< By the way, it's really annoying that I can't cut and paste from the

The IE embedded web browser does some really funky stuff with controls when
you enable certain functionality, so for now it has to stay disabled.

I was trying to alter the size of a panel (normally hidden/zero height) based on a button click.  I was calculating the size of a panel and a grid so they would both fit in the client area after the panel was "opened".  Unfortunately, I've since removed the offending code having moved on to some other experiments with my new "toy".

No problem - if you see anything like this again, please let me know.

Just got this kind of thing again.  I'm setting Left and Top of the main form in OnCreate.  Works ok in OnShow.

Can you send me a project that demonstrates the problem ?  I just want to
make sure that I'm getting everything exactly right.

All I did was create a new project, Add a line "Form1.Left := 100;" in the OnCreate event.  Works ok in the OnShow event.  Verified it just now.  Although the test is slightly different than my original problem, it's still complaining.  The message in this case is "unit1_form1 is null or not an object".

The problem is the use of the 'Form1' variable.  Currently (I'm looking at
solutions for this), you have to use Self in the OnCreate for a form if you
want to get at the current form.  The Form1 variable isn't initialized yet
at the point that the OnCreate is called (form creation works a little bit
differently due to the way that JS works).

So, if you use this you'll be all set:

  Self.Left := 100;

If you have any other questions, please let me know.
