meaning of error message

[shmokarami]

Could you Please help me? what's the meaning of this error message?
"Windows has triggered a breakpoint in Network1.exe.

This may be due to a corruption of the heap, which indicates a bug in Network1.exe or any of the DLLs it has loaded.

This may also be due to the user pressing F12 while Network1.exe has focus.

The output window may have more diagnostic information."

Windows stopped executing the program. It may be due to a corruption of the heap, which is most likely a bug in the program or one of its DLLs. You could also have accidentally pressed F12 on it. Try checking the console/debugger window.
