The first thing to check would be if the ObjIndex is actually the index
of a "Control" or some other kind of form element. Controls are
buttons, checkboxes, triggers, etc, but NOT labels for instance. Bob.

I am facing a strange problem for the last two months in my application,
when I try to debug on palm os emulator 4.21,
Palm emulator flags an error "myapp(1.0) called SysFatalAlert with the
message "Control.c line:543 "Not a Control Object"
What I am trying to de is just setting the label to a new text string.
Running on simulator 5.0 or tungsten W/T does sometimes stops at that line
but again sometimes goes well ....... :0(
Here is the code:
Please help if anybody know what could be the reasons.
void ToolsDrawControl(FormPtr frmP,char* label, UInt16 ObjIndex)
{
ControlPtr ct=NULL;
if(label)
// if(label!=NULL)
{
UInt16 index;
//int pt;
index = FrmGetObjectIndex(frmP,ObjIndex);
//pt = FrmGetObjectType(frmP,ObjIndex);
if (index == frmInvalidObjectId)
ErrAlertCustom(ErrOKAlert,""," ToolsDrawControl-Invalid Control Specified
", label);
ct = FrmGetObjectPtr(frmP,index);
if(ct)
{
//CtlSetUsable(ct,false);
CtlSetLabel(ct,label);
//FrmCopyLabel(frmP, ObjIndex, label);
}
}
}
