i have a textbox in form. i want to write there in the textbox, the path (ex: D:\temp) and after that, i want to create this path.
I tried to use this regex but is not working! i want the first letter be upper but is not working. Also i want the string contain ":" and "\" just once. And after ":\" i want to insert some string lowercase
 @"^*[A-Z]*[:]*[\]*[a-z]$"
Have some sugestions ? 
Thanks a lot !
