I gotta say, you are always on the ball, and prompt. Thanks a lot for that!
No worries mate, glad to help!
This is a class called VoiceRecorder.cs ... It's fairly simple to use. It's a slightly modified version of one I found on thecodeproject a while back (I'm VERY sorry, I can't find the original URL) it launches the inbuilt audio recording facilities of Windows Mobile.
You invoke it by using
-
VoiceRecorder vr = new VoiceRecorder("myFileName.wav");
-
vr.show();
-
And it behaves just like a dialogbox.
It took me AGES to try and get something like this working, so it's always nice when we can skip out all that hassle and help eachother.
