If you find it, let me know. I wouldn't mind quoting on jobs, downloading some code, and getting paid. Although, it scares me that a hospital doesn't have better ways of checking who works on their systems

I wouldn't mind that either. Code reuse? Roll eyes | :rolleyes:

have you done any requirements gathering or consult with the hospital about what they need in the project? I'd start with these tips first rather than going the lazy way and looking for something that has already been done...

hey all, hope you're all well

i need help with creating a dvd player
well mainly just getting the dvd to play

in visual basic 2005 express

i have these two:
MSWEBDVDlib
MSVidCtlLib

its supposedly better to use MSVidCtlLib for DVD on XP according to the MSDN

but i just cant get it to play anywhere

(its for a school project)

thanks

To play a DVD, you need to do two things:

1 - use the windows media player control and
2 - make sure you have the MPEG/DVD codecs installed.

There are free DVD decoders on the web, I am pretty sure. Without one, it's just not going to work.

no i didnt want to use the windows media player control

OK - well, even if you find some harder way of doing things, it's still not going to work without the DVD codecs installed.

yeh i have the codecs

i was using:
Imports MSVidCtlLib

and than

Dim WithEvents dvdjunk As MSVidWebDVD = Nothing

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
dvdjunk = New MSVidWebDVD

dvdjunk.Run()
End Sub

and i keep getting "The method or operation is not implemented."

than if i use

Imports MSWEBDVDlib

amd

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
dvdstuff = New MSWebDVD
dvdstuff.Play()

End Sub

than i get

COMException unhandled
The data necessary to complete this operation is not yet available.

so im not sure what im missing or what im not implementing ("The method or operation is not implemented.")

??

thanks for the help though so far, i appreciate it

You're not using Vista are you ? The docs say this is available on W2000, XP and S2003, but says it could be removed in the future ( unlike windows media player )

http://msdn2.microsoft.com/en-us/library/ms787412.aspx[^]

I don't see a run method in the docs. I see 'play'.

The name implies this is designed for use in web apps, not windows apps. Why won't you use WMP ?

Its_Me_Lenny9-Jun-07 1:05

9-Jun-07 1:05

if i use WMP will WMP need to be installed on the machine?

Christian Graus9-Jun-07 1:09

9-Jun-07 1:09

Yes, but isn't it always ?

This isn't going to work for anything prior to W2000, and if it works for Vista, there's no guarentee it will work after that. I am certain that W2000, XP and Vista come with WMP installed.

Its_Me_Lenny9-Jun-07 1:14

9-Jun-07 1:14

its a "high school certificate" software project i'm working on and it's meant to show a little more difficulty than just using windows media player

hence using the MSVidCtlLib

so if all it is is using the WMP it wouldnt really go along the lines of how im meant to be building it, so its not me being picky its me trying to get good marks so i dont fail

Christian Graus9-Jun-07 1:17

OK - I'm not sure if managed directX will play DVDs, but either way, you're going to tell a component to play video for you. Really, you're not going to write a player, you're writing a wrapper for an existing player. If I was marking you, I'd mark you down for doing things the hard way ( which is never smart ). You'd do better to think of ways you can add functionality that is unique to your player ( or at least involves you writing some code that doesn't just call a built in component ).

The docs look to me like this component has an interface very similar to the WMP interface, once you get it working, it will wrap playing a dvd, just like WMP does.

Its_Me_Lenny9-Jun-07 1:24

id probably get marked down for doing it the WMP way aswell, he expects a bit from me, he looks at our programming skills sort of than says yes or no to the project that we choose.

seeing as it may be to difficult or not difficult enough do you know of some sort of project i could do?
it can be anything really from a game to a whatever, we have 8 weeks i think and it needs full documentation, the dvd player was my only idea, ity also has to be ethical, so an mp3 player wouldnt be for instance (because mp3's are technically illegal in a way)

thanks for all the help by the way, id been researching all day and just getting errors, i did actually tho get the sound playing from the dvd and that was it, it somehow leaked, but im not sure how i did that because i didnt notice than i changed the code

The mark of a good programmer (or software developer) is that he/she uses the right tool for the right job (when available - and campaigns for it when not)

Personally, if I were doing your project I'd be using the Windows Media Player and I've been programming for almost 22 years now.

Its_Me_Lenny wrote:

Then write a game. It would be a much better demonstration of your skills that wrapping an existing component with a few buttons - which is really what you are doing.

Go for something like noughts-and-crosses (Tic-Tac-Toe in some locales) or even SoDuKu.

WTF? No they are not. Only if they contain copyrighted content and you don't have the rights to that content! You can download something like Dot Net Rocks[^] as an MP3. That is not illegal.

Where on Earth did you get the idea that "MP3s are technically illegal"?

Except in Europe for Win XP N and Win Vista N, courtesy of the EU. But I've yet to encounter anyone who owns such versions!

According to my MSDN Subscription as I can download them. Not sure why I'd want to download crippled versions of Windows, but it is there all the same.
