Hello All,
I have been tinkering around with some C# applications that I wrote
over the summer for my job. The one that I have a question about is a
simple app that connects to network printers. The user chooses which
lab printers they want to map and it will map them. I was trying to
incorporate a loading bar so that the user doesn't sit there and keep
clicking my "Map Printers" button since right now it seems like the
program just stalls.
Now my problem is that when run the program goes into a "This program
is not responding" phase but will still map the printers so to the end
user it appears that the application just crashed and didn't map their
printers.
Any help/ suggestions to make my app better would be greatly
appriciated.
Booter
