The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Microsoft sound object MCI32.OCX and Windows Sound Recorder Recording appears to work but length stays at zero

Asked by GHG-RCH in General Multi-Media Software, Computer Sound Cards, VB Objects

Tags: Microsoft sound object, recording, no progress, MCI32, Windows Sound Recorder

We write a Digital Dictaton Product.
We use the Microsoft sound object in MCI32.OCX
On some systems when a recording is started the recording appears to progress, no error is returned but the recording length does not increase.
This is intermittent. On one site with several hundred users it occurs maybe once or twice a day seemingly at random.
We are using USB devices, primarily Philips Speech Mikes.
When this happens closing our software and using Windows Sound Recorder (which I think uses the same object) the same thing happens.
Sometimes unplugging and re-connecting the USB device resolves the problem
If not then sometimes rebooting the machine works
Sometimes rebooting several times does not work, and the problem occurs just running Windows Sound Recorder, so I don't think anything our software is doing is causing the problem.
Any ideas as to what might be causing this problem, how to detect it and is there any way of correcting the problem in software.
I now detect the problem by monitoring the file length and reporting when the recording length is static when it should not be, but I have no way of fixing the problem in software.
