Visual Basic Source Code Request.

Could someone make a quick example or source code for VB express 2005, for a screen recorder that would record sound and pictures and put it in a file such as avi? I would like this as refrence for something I am trying to work on, but am not shure how to do all those things...

Hi anthrax123,

Firstly, Visual BASIC is not a suitable language for media capture at such a level.

For capture of sound/video you will need to 'talk' directly to their corrosponding device drivers. This is typically accomplished by installing a filter-driver which intercepts the media throughput.

To develop a filter-driver you will need a good knowledge of operating systems and low-level development. This is mainly because you will be operating in kernel-mode where-in there is little to no security which means a poorly written driver can easily corrupt your whole system.

Although, I'm sure there are pre-written interfaces available which would enable you to still use VB. I suggest you just google for one.
