The first problem I'm trying to resolve is when I try and remove a
Dynamically created field control, I'm creating the control with the
following code:
case ctField: // create a text field
TestControls[i].iControlID = giNextControlID;
giNextControlID++;
nfrmP = FrmGetActiveForm();
NewField=FldNewField ((void **)&nfrmP, // form
TestControls[i].iControlID, // id
TestControls[i].x, // x
y, // y
50, // width
12, // height
stdFont, // font
50, // maxchars
true, // editable
true, // underlined
true, // singleline
false, // dynamicsize
leftAlign, // justification
true, // autoshift
false, // hasscrollbar
false); // numeric
// set the value of the field
SetTextPtr(NewField, TestControls[i].Value, false);
break;
------ SetTextPtr code
Boolean SetTextPtr(FieldPtr field, char *s, Boolean redraw)
{
MemHandle h = FldGetTextHandle(field);
char* p;
if (h)
{
FldSetTextHandle(field, NULL);
if (MemHandleResize(h, StrLen(s) + 1))
return false;
}
else
{
h = MemHandleNew(StrLen(s) + 1);
if (!h)
return false;
}
p = (char *)MemHandleLock(h);
StrCopy(p,s);
MemHandleUnlock(h);
FldSetTextHandle(field,h);
if (redraw)
FldDrawField(field);
return true;
}
And then removing it with this code:
frmP = FrmGetActiveForm();
obj2NDX=FrmGetObjectIndex(frmP,TestControls[ndx].iControlID);
if (obj2NDX != frmInvalidObjectId)
{
FieldPtr field;
field = (FieldPtr)GetObjectPtr(TestControls[ndx].iControlID);
MemHandle h = FldGetTextHandle(field);
if (h)
{
SetTextPtr(field, "", false);
}
error=FrmRemoveObject (&frmP,obj2NDX);
}
When running this in the emulator (4.0 Debug rom) it reports a memory leak.
Any ideas of what I'm doing wrong?
