DirectShow: Cannot assign Filename property of Dexter MediaDet object

[Hartmut Schroth]

Hi,

I want to use the Dexter 1.0 Type library in a VB.NET Web
project.
So I created a project reference to the com object
Interop.DexterLib.dll and added the following code to the
load property of the main form


Dim Det As New DexterLib.MediaDet
Det.Filename = "C:\SomeFilename.avi" ' existing avi file
.........

The program hangs when it reaches the 'Det.Filename = '
command.

I tried exactly the same in a VB.NET Windows.Form project
and everything works all right!

Is it not possible to use the Dexter Lib in a Web project?

Thanks for help in advance.

Regards

Hartmut

ASP.NET runs as a local user named ASPNET, which by default has a very weak
permission set, and can't access many local directories. You can just grant
ASPNET access to the file and try again.

Hope this helps.

Hi,

that is what I tried already: ASPNET has full control over
the file. That semms to have nothing to do with the hang
up.
Do you have another idea?!

Thanks in advance

I tried the code and it seemed to be working for me. What is your
environment? Mine is Windows 2003, .NET Framework 1.1, and DirectX 9.0b.

To double-confirm that ASP.NET have access to the file, you can just create
a BinaryReader for the file and close it before using the MediaDet object.

Hope this helps.
