Hi,

program sent message to a mobile phone,phone replied a number and some informations,and my program connected a oracle database,downloading some data using the number,some data was sent to printer.

Today,my program was installed in factory...had a mistake.
Program wasn't run in some PC.

The computers has a lot in common.
1.Windows 7
2.Operation in C driver required administrator privileges.
3.if program was installed in C:\,program running would have a warning "reject access".
but if program was installed in D:\,program running would have issue phenomenon.

The following was issue phenomenon.
1.Serial communication was no problem.
2.Downloading data was no problem from database.
3.The program was running,but framework of the program crashed.
4.CPU usage rose to 58%.

Has anyone encountered this problem？plz help!

Help with what? You need to debug your code to figure what the problem is.

Everyone has encountered this problem. You have not completed the testing and debugging phase. You need to work out where the program is getting to before failing. Are you running a release or debug version? A logging window may help.

hi,thank you for your help.
I forgot to write i am a new coder and the program was my frist program.
debug version was run.
the issue phenomenon did not happen on all Win7 PC.
The C drive operation did not require administrator privileges,like this Win7 PC did not have the issue phenomenon.
And this issue phenomenon would be happened when the fist process was finish.
I think I should debug my program on issue computer.

Yes you can only debug on a computer that displays the problem. In debug version assert() statements can be a very useful tool. You can insert as many as you like and they will be ignored in release version.

your program writes some data in C:\Program which isnt allowed because it is a protected directory. Look out for the file and use a User directory.
