Error When Running project the second Time

[Dubya007]

I have a project that will run while I'm working on it only once. The second time I try to run it I get the following error.

The operation could not be completed. The process cannot access the file

Does anyone know what that error means and why I'd have to restart my computer every time I want to run the project a second time?

Everytime you 'run' your project, VB will attempt to compile it. Its possible that when you close your application that file is not closing correctly, ie, its still running! You can check task manager to see if this is the case, and if so terminate it. Try this first and if it is the case you should work out why your application is not closing correctly.

I Think i've got it worked out actually. When I open it on another machine to work on it, the project compiles just fine.

That doesn't exactly answer why it is wrong . App file read-only? No permissions, ie run as admin?

Thats true it doesn't. I think it may have something to do with not having serial ports on the machine in question.

So it could be that your application is not closing due to a fault on shutdown code ....

That could be. I need to learn how to program expected errors and not expected errors. Its been so long since I've done any VB(muchless vb.net). I'll have to find some tutorials on error handling
