prompting user for bitmap name

[samv12]

i have a small question. I am using the following to save a bitmap

bmap.Save("name1.bmp")

my problem is name1 is a variable name and not the name i want the bitmap to be saved under. So if the user enters ' circle1 ' in the textbox ( i.e name1 = circle1) i want the bitmap name to be circle1.
Thank You
Sam
