Hi,
When you are creating new Objects, frmPP will be changing and you have to
use the new frmPP returned when you create the new object.
You are using the value that becomes invalid once you create a new object.
FormPtr * frmPP = &frmP;
>From the documentation you can get the explanation :
frmPP <-> "Pointer to the pointer to the form in which the new list is
installed. This value is not a handle; that is, the old formPP value is not
necessarily valid after this function returns. In subsequent calls, always
use the new formPP value returned by this function."
I have tried the code below its working fine..(here I am not using a
separate variable for frmPP)
FormPtr frmP;
ControlType * gctl;
frmP = FrmGetActiveForm();
gctl=CtlNewControl (&frmP, 1010, buttonCtl, "Test",43, 110, 12, 36, 0, 0,
false) ;
FrmHideObject(frmP, FrmGetObjectIndex(frmP, 1010));
Please try the above steps.
Thanks

Subject: FrmRemoveObject
Hi to all, I am having a problem when I try to use this funtion.
FormPtr frmP = FrmGetActiveForm();
FormPtr * frmPP = &frmP;
FrmRemoveObject ( frmPP, FrmGetObjectIndex(frmP, 7000));
The error I get when I execute the program is a memory manager error. Any
ideas or examples
on how to use the function? Just in case, the id exists since I created the
control dynamically. Can
this affect the function, if I created the control dynamically?
Thanks,
Nicolas
