Passing parameter to Crystal report

Question

Hi All,

i have a scenario like this.

I have a windows form and it contains a crystal report too.
i can generate the crystal report without any problem. but i have one textbox in the form and i want to get that textbox value to the crystal report textbox value.

if i brief it,

i have a form with one textbox, button and a report.

user enters value and click on the button. then default report is generated and whatever the user entered value is displayed in the header section.

can anybody give me a hand to do this.

Thanks in Advance,
Max
