WMPLib.dll And Burning CDs
Feb 13, 2010
I am using Windows Media Player library (WMPLib.dll) in my application. I wanted to make CD Burning wizard, because WMPLib.dll has ability to burn audio/data CD's. I declared an object which can erase or burn CD:
Dim CDBurner As WMPLib.IWMPCdromBurn
Dim WMP As New WMPLib.WindowsMediaPlayer()
[CODE]...
I get exception with message "Attempted to read or write protected memory.". I have an option "Full Trust Application" enabled in Visual Sudio. Is there anything I can do about this error?

we developed an application. it has windows media player control.
Note 1:
2 DLL Files(Interop.WMPLib.dll And AxInterop.WMPLib.dll) is for Windows Media Player Control, and automaticly add by visual studio.
Note 2:
Visual Studio 2008 / .Net Framework 2.0 / Windows XP & Vista & 7
If use dlls for windows xp(Windows Media Player Control)
run app in windows xp = do not have any problem.
run app in windows vista and 7 we do not have media player control.
if use dlls for windows vista and 7(Windows Media Player Control)
app does not run in windows xp
and we do not have any problem in windows vista or 7.

I have to burn the program I made but I'm afraid about the directories I include in the program.
PictureBox1.Image = Image.FromFile("C:\Documents and Settings\Marvin\My Documents\Visual Studio 2010\Images\Edsger Wybe Dijkstra.jpg")
If I burn it to a Disc, the image will not show up.Even I put them in one folder, It will not work still.How am I suppose to burn it on a disc without having any problem?

There's a number of postings about IMAPI in .NET, including these:
[URL]
But I can't say they're straightforward. First link looks good, though its C# WinForms realization doesn't allow simple re-using in VB.NET project without conversion.I only need to burn a list of files to a CD/DVD and that's it. Any thoughts? Freeware/open-source is preferred.

I have been looking all over trying to find a sample to guide me through burning a basic audio or data cd using the windows media player sdk. I have been using the library at msdn as a guide so far but I am stuck at where they tell me to:
"Before you begin burning a CD, you must first call QueryInterface through an IWMPCdrom pointer to retrieve a pointer to the IWMPCdromBurn interface. By using the isAvailable method, you can determine whether a particular CD drive can burn CDs, whether there is a CD in the drive, and how the CD can be used."
I do not see any queryinterface iniwmpcdrom properties and vb.net doesn't support pointers.. so not sure what to do Does anyone have any samples?

I'm trying to understand how to route the events of my IMAPI2 burning progress but not sure how to do it. I've coded event handling before, but just not familiar with the IMAPI2 library so having some trouble.
This is their sample code in c#:

I'm trying to make a simple equalizer I have my windows media control and a trackbar, this is the code im using.
Private Sub TBGLevel_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TBGLevel.Scroll
Dim equalizer As WMPLib.IWMPEqualizerSettingsCtrl
equalizer.gainLevel1 = TBGLevel.Value
End Sub
Upon moving the trackbar I get this error
NullReferenceException was unhandled Object reference not set to an instance of an object.
I also tried
Public equalizer As WMPLib.IWMPEqualizerSettingsCtrl
Same error occured.Basically i hit play so it would go through my playlist on the form then attempted to move that gainlevel and it produced the error.

I am using Windows 7 64-bit and Visual Studio 2010 (VB.Net)
I am trying to write a media player using the wmplib.dll for playback. Everything is working but I found a one problem I can't find an answer to. How do you find the songs duration before actually playing the song? the code I am using is below.
I get an error when I try to update the slider with the current position. The messagebox returns all zeros. (i.e. 0 - 0 -0 ).
' SET FILE NAME
Dim sFile As String = "D:MusicSongsArtistsEaston Corbin�1-Easton Corbin�4 - The Way Love Looks.mp3"

Hmmmm having discovered that using the mciAPI doesn't utilise 5.1 sound, but using a virtual WMP does - I started a new approach to my multimedia project using some code from the net. BUT I keep getting exceptions (particularly with type casting). In the subrountine 'Player_PlayStateChange'.
The listing (see below) is now well commented by me. Can anybody please help concerning the damn annoying exceptions and stop me pulling my hair out.

The MSDN documentation for WMPLIB states that syncing to device is not supported in .NET programming, only C++.Is there, however, a simple wrapper class or DLL that can be used to interface between a .NET program and the nescessary C++ code?Or is there a better way to sync files to a device using VB.NET? Are all devices suited/compatible with just a simple filesystem.copyfile ?

I need to get the current song in Windows Media Player, preferably using the wmp.dll library. There's documentation on MSDN [URL] but none of the resources I've tried have worked, even though I referenced the DLL and imported. Note that I'm using Visual Basic 2010 Express

I am having another issue with WMP in VB.NET 2010.I wrote an app using WMP in VB.NET 2010, using .NET Framework 4.0 of course, but had to change the framework target to 3.5. After doing this, the WMP component does not work. How, if I even can, fix this problem so that the program will run on .NET Framework 3.5? The error says that it could not load AxInterop.WMPLib.dll because it was built in a runtime newer than the currently loaded one.

When I iterate the media items in a Windows Media Player playlist and set the properties of a user-defined class to the attributes of a media item, the first n rows of the playlist are populated with useful information; however, the remaining rows are empty. If I perform the same operation but access the media items directly (e.g., display the attributes to the console window) then all items in the playlist are populated properly.
Here is an example of the output showing the condition:
Inserting song "The Arrest" from album "Jesus Christ Superstar [MCA Original Cast Recording] Disc 2" into database...
Inserting song "Peter's Denial" from album "Jesus Christ Superstar [MCA Original Cast Recording] Disc 2" into database...
Inserting song "Pilate and Christ" from album "Jesus Christ Superstar [MCA Original Cast Recording] Disc 2" into database...

I have a Form with a Media Player in it. Which plays a Song.
[Code]...
It's playing in the background since the Form is hidden. When I play itin Debug, everything works fine. When I run the app outside Debug, I get this error: [URL] The Music File is there, but strangely, there comes this weird error.
