If you have a console application, then: printf ("\7"); will do the trick. Unfortunately in a GUI based project this method will also leave a console window visible afterwards...

The Windows SDK defines a function named Beep(), which allows you to play a specified frequency for a specified amount of time on the PC speaker.

if it is not already done, you need to install the Windows SDK which is bundled with CVI, and of course, #include <windows.h>.

yes,I used the Beep(),but no beep sound on PC Speaker. There is beep sound on the sound card.

The Programmer's Toolbox (toolslib\toolbox\toolbox.fp) provides StartPCSound() and StopPCSound(). They should do.
