[Guest umarzaman]

<pre>hi

i have developed a windows mobile based client app ........ i only want to send a simple string to the server running on pc via wifi connection...........i have already written the code and abt 2 months back it was working fine on emulator.....but recently when i try to execute the code i didnt work on emulator nor on the device on which i deployed it..............when i press the login button the application does nothing.......and in the output screen i get....."The thread 0xb69a647e has exited with code 0 (0x0).".............it dnt send any data to the server.....but when i run the exe of the code in debug folder it works fine and sends data to the server..... i am so confused that if exe is sending data why isnt the data sent through emulator or mbl device ....i am posting the code below...any help would be much appricieated.....
