Hi all,
On my form there is one Edit Box, in this edit i have is a short
text, in the start of my code i have this lines -
Form1->MyEdit->SelStart = 0;
Form1->MyEdit->SelLength = Form1->MyEdit->Text.Length();
Form1->MyEdit->SelectAll();
Form1->MyEdit->Refresh();
I expected that after running this lines i will see the text in
the Edit box selected (in Blue color like i selected it with my
mouse) , but although this lines of code are executed i don't
see any part of the text selected in the edit box, it's stays
black text on a normal white background.
The question is - why? .....
Thanks,
Ramy

doing so from within the class, you don't need to qualifiy it
with the class name.
In other words, if the line:
Form1->MyEdit->SelStart = 0;
is contained within the Form1 class, then you can write the
line as such:
MyEdit->SelStart = 0;
coded better, I see no reason for it not to work. Try moving
it to a button click just to be sure:
void __fastcall TForm1::Button1Click(TObject* Sender)
{
ShowMessage( "About to set the edit" );
MyEdit->SelStart = 0;
MyEdit->SelLength = MyEdit->Text.Length();
OR but not both
MyEdit->SelectAll();
}

You must either set focus to the edit-field (MyEdit->SetFocus()) or set the
HideSelection property of MyEdit to false if the selection should be visible
without focus.
