Have you ever taken a look at the MSDN?
Try www.msdn.com and ask your question in there - not to brush you off or anything, but they can answer your question with a greater level of detail and you'll get more out of it that way.
Trust me, as a programmer myself, the MSDN and I have gotten very close over the years.

I am making my own version of a media player. The progress is going great except that the DS control (msvidctl.dll) will not play MPEG-2 files. I thought that the control would handle this automatically. MSDN says that we need to specifiy the MPEG-2 Demuxer and other stuff. Could anyone please post some sample code (VB would be prefered, but otherwise I can join the peices from other languages). I am not using Microsoft.DirectX.AudioVideoPlayback.dll, even thought it works great I cannot combine this assembly with anyother dll using ILMerge.
I have also built a DVD application using the same dll, the only help I need is figure out how to control the dvd navigation filter. At the moment I use
DScontrol.view("DVD:")
This snippet will allow me to play dvds but I cannot control which drive I want to play i.e. If I have 2 drives with dvd movies in the them, the drive that has the master setting on the IDE bus or lower drive letter(dont remember which one of the 2) will play everytime. If I eject one of them, the other one will play. Does anyone know how I can command a specific drive to play a dvd movie? Your help is greatly appreciated.
Thanks

Figured out the first part. I needed to install an "MPEG2 decoder." But I already have PowerDVD 6 w/ valid DX and WMP10 decoder, for some reason reinstalling PDVD allowed my MPEG2 playback. Another weird thing is that WMP10 and PDVD both played MPEG2 files and DVD but my DS app was throwing exceptions (even though they have the same base classes) ?!#!@# Gotta love Microsoft stuff  .
However I still need help on the second part, the DVD navigation filter. Any help would be great. Thanks

you could use the tag member to store any non-displayed object on your combobox (useful when used to search on another point than the caption...)

Try using visible property
Something like
If DeptID = A then
label1.visible = false
textbox1.visible = false
else
label1.visible = true.......

You may like to set AutoPostback property of control to true. Then you should be able to handle the control values using codebehind.

You didn't add a reference to System.Web.dll in your new project.

In a winform , Me.Close() will active a close event.
However , this event could not be edited in vs.net 2005 beta 2.
Why?
|
|
|
|
|
It's an event, you subscribe to it, you don't override it.
It's explained in the VS 2005 beta 2 docs, do a search there.

I search in google with these keywords:
VS 2005 beta 2 docs close event winform
The result is not good.
Should I write the close event myself?
|
|
|
|
|
Search http://msdn.microsoft.com[^] for "Form.Close" or "Form.Closing event".

Why didn't you install the documentation when you installed beta 2 ? If you don't have the docs on your hard drive, do what Dave said.
