Rif.: Play a .wav file in LabWindows CVI

[MatGIL]

Hi everyone,

I'm a french student in intership. Currently improving my programm, I have to warn people when a certain level of electromagnetic waves is reached.

I would like to warn them by a sound and a red light. I already found an example in Labwindows/CVI data but i can't put it in my own programm. So I ask you if there is a way to play a .wav file when the critical level is reached. (Or an other type of file maybe if it's easier).

Thank you for your help,

Matthieu

Take a look at this small sample I coded a few years ago: it shows you how to use PlaySound to play a .wav file.

Hi

There is a sample project that should help you. If you go to find examples--> In search fill with "wav".

You will find sndplay.cws project. Otherwise, it is stored in :

C:\Users\Public\Documents\National Instruments\CVI2015\samples\sdk\audio

I know, i already found it, but i couldn't take the "playsound" function. I had a lot of problems. However, I'll try to use the file of Roberto.

I'll tell you if it worked.

Both PlaySound and sndPlaySound functions are available in Base and Full version of CVI, but to use them you need to:

• Install the interface to Win32 API (formerly Windows SDK)
• #include <windows.h>
• #include <mmsystem.h>
• On older versions of CVI, add WinMM.lib to your project

I'm using LW2009. The PlaySound function works, thank you ! 🙂 It helps me a lot (I had an other solution "printf ("\7"); but i was not good)

Thank you again,
