Ok.. I used this to change a Text Field
in my apps...
//this is where I need to change the label
if(StrCompare(ArmedState, "0") == 0)
{
StrCopy(ArmedState, "1");
Handle AText = MemHandleNew(8);
StrCopy(MemHandleLock(AText), "Armed");
MakeMyBeep(shortBeep, 3);
ChangeTextLab(MainText164Field, AText);
MemHandleUnlock(AText);
MemHandleFree(AText);
}
else
{
StrCopy(ArmedState, "0");
Handle DText = MemHandleNew(10);
StrCopy(MemHandleLock(DText), "Disarmed");
MakeMyBeep(shortBeep, 5);
ChangeTextLab(MainText164Field, DText);
MemHandleUnlock(DText); <--Invalid
Handle error
MemHandleFree(DText);
}
MemHandleUnlock(GCode);
//this is the changing label function...
static void ChangeTextLab(Word FieldID, Handle textH)
{
Handle oldTxtH;
FormPtr frm = FrmGetActiveForm();
FieldPtr fldP;
fldP = FrmGetObjectPtr(frm, FrmGetObjectIndex(frm, FieldID));
oldTxtH = FldGetTextHandle(fldP);
FldSetTextHandle(fldP, textH);
FldDrawField(fldP);
if(oldTxtH)
MemHandleFree(oldTxtH);
}
But It give me a invalid handle error...
Does someone have a clue....
Or is there a better way to make something like this
simply change the text on a label or non-editable textfield
