OS: Windows 7
IDE : .Net Visual Studio 2008 and 2010
Language : C#
VLC : activex axVLCPlugin v1 and v2
Project : x86

After adding the activex com component axVLCPlugin v1 or v2 to a windows form, it compiles ok. Run it and the entire IDE (Visual Studio) shuts down and restarts.

I have registered the axvlc.dll. I have tried this on 3 separate PC's with the same results.

In my project reference : AXVLC and AXAXVLC both version 1.0.0.0

The winform code is a simple form window, no other code or controls.

I have searched our forum for similiar results but no leads.

Anyone experienced this before? Thanks!

Have you tested VLC 2.0.0 ones? They are MUCH better stability wise.

Thanks for the suggestion.
No I haven't, where can I get that version?

I've tried several releases with the MSVS 2008 and 2010 IDE's on three separate PC's with the same IDE shutdown error. Any ideas or suggestions are welcome.

So it also crashes with VLC 2.0.0 versions?

6:00pm Oh, new release. I'll give it a try and report back. Thanks!

7:00pm : Dratz ! Sorry to say same results. IDE shutdown. Also tried cleaning the registry with CCleaner then reinstalling VLC 2.0.0. WinForm app using VLC Plugin as noted above.

string movie = @"C:\Lab_2008\VLC_EmbeddedTest2\VLC_EmbeddedTest2\Movies\MISP.mpg";

private void button1_Click(object sender, EventArgs e)
{
try
{
if (File.Exists(movie) == false) { MessageBox.Show("Movie not there: " + movie); return; }
axVLCPlugin21.playlist.add(movie, null, null);// "Video1", null);

axVLCPlugin21.playlist.play();
}
catch (Exception e1) { MessageBox.Show("Error Play:" + e1.Message); }

}

private void button2_Click(object sender, EventArgs e)
{
try
{
axVLCPlugin21.playlist.togglePause();
}
catch (Exception e2) { MessageBox.Show("Error Pause:" + e2.Message); }

}

private void button3_Click(object sender, EventArgs e)
{
try
{
axVLCPlugin21.playlist.stop();
}
catch (Exception e3) { MessageBox.Show("Error Stop:" + e3.Message); }

}

It was a good try. I'll continue working on this and will post any success I may find, as always : open to any ideas / suggestions.

Well, I've actually spent a lot of time testing axVLC for embedded activex in ms C# visual studio 2008 and 2010 across Windows XP and 7 with the same problems so I guess I'll have to throw in the towel on the axVLC.dll

Has anyone had any success with other embedded video display activex controls that might be similiar to VLC ? How does MPlayer match up ? Is it a possibility ?

Just a side thought : Windows Vista and Windows 7 have what's called DEP : Data Execution Prevention.

I see this causing crashes with older ActiveX controls that give the error "attampted to read or write protected memory".

I wonder if this DEP stuff is a clue.

This is an old post but I may have found a potential solution. I'm testing this now but wanted to post in case I forgot too or if anyone else wanted to try it out:
To fix: click start, type "cmd" into the search box, right click "cmd.exe" in the search results, select "run as admin",
then run this command:
regsvr32 "C:\Program Files (x86)\Internet Explorer\ieproxy.dll"
