RE: Setting the text of a label

[Eric]

Are you trying to set a Label or a Field??

For Label, use FrmCopyLabel - The best!  Very easy to use and no hassle.

For Field, here is a little sample of how I set a 1 or 2 in a Field:
        Handle txtH;
        txtH = FldGetTextHandle(FrmGetObjectPtr(frmP,
FrmGetObjectIndex(frmP, 1204)));
        if (txtH == NULL) {
                txtH = MemHandleNew(2);
        }  else if (MemHandleResize(txtH, 2) != 0) {
                MemHandleFree(txtH);
                txtH = MemHandleNew(2);
        }  //IF 
        StrCopy((char *)MemHandleLock(txtH), "1\0");
        MemHandleUnlock(txtH);
        FldSetTextHandle(FrmGetObjectPtr(frmP, FrmGetObjectIndex(frmP,
1204)), txtH);
        FldDrawField(FrmGetObjectPtr(frmP, FrmGetObjectIndex(frmP, 1204)));

Hope this helps!

        I recall reading somewhere that you can 'legally' fetch the pointer
to the
        label's textfield (the char array...) and copy whatever you want in
to it.
        The drawback of doing this is that you can't exceed the size of the
string
        set at compile time. Anyway, I tried it a few months ago and it
worked.
        Can't provide you with an example though. :/

        If this was covered in the thread below then I apologize.

        Take a look at the thread: "need help using CtlSetLabel()"
        In short, a label is not a field nor a regular control.
