DirectPlay Causes vb Program To Hang

Currently i am using DirectPlay8 to create a connection between the client and the server. I dont know why everytime when i played my project and when there is error, it will hang and doesn't allow me to end my project to debug the program. I would like to know this is due to what reason .

More than likely it's due to the way your code is set up? Maybe if you posted the code you're using we could tell what's going on.
