Need help on MCI

John502

Hi, I have created one application that will used play calls, i have developed this application using MCI (Media Control Interface). I am running my application on the machine which don't have sound cards, that time i am getting one error related MCI. but that error message is not irrelevant, now i want to change that error message. Or before starting my application i want to check whether that machine has sound cards installed or not. Can any one help me out how to check about the sound cards.. It is very urgent requirement for me... Thanks in advance...

Hi aks, Thanks for your reply.. I have checked this function on my machine, which is having sound cards, i am able to get the return value is 6. I have checked the same scenario on the machine which doesn't have sound cards, there i am getting the return value as 1. I have tried to play mp3 song on that machine, but not able to play that. I don;t know based on msdn help if no sound cards are enable, this function should return 0 instead of non zero number... Can you please explain me this scenario...? Thanks in advance...
