What I want to do is:
click on button1 in form1---> loads form2 ---->set focus to a textbox1 in form2 and show IBeam Cursor there.
I tried textbox1.Focus() in Load, but it only do it for the first time I click button1, when I click button1 again, it loads form2, if I type something now, it won't show in textbox1, I don't know where it goes, no cursor in textbox1 either.
Then I tried assigning textbox1 the lowest 'TabIndex' on form2, still won't work. Why? What else can I do?
