Using DSOFile in ASP.Net???

Curtis Tammany · Sep 26, 2003

Hello-

Can someone tell me if DSOFile.dll can be accessed within ASP.NET?

DSOFile.dll is registered and I have no problem using it in my .ASP scripts. I have tried the following:

Dim oFilePropReader As DSOleFile.PropertyReader
Dim oFileProperties As oFilePropReader.GetDocumentProperties("C:\MyDoc.doc")
Response.write ("<table>" & vbCRLF)
Response.write ("<tr><td><B>Title: </B></td><td>" & oFileProperties.Title & "</td></tr>" & vbCRLF)
..
..
Response.write ("</table>" & vbCRLF)

All I get is Type 'DSOleFile.PropertyReader' is not defined.

Also - Why isn't the functionality of DSOFile built into the System.IO class????

Thanks-

Curtis

You haven't instantiated any of your objects. In any event the following works for me:

Dim oFilePropReader As New DSOleFile.PropertyReader()
Dim oFileProperties As Object

oFileProperties = oFilePropReader.GetDocumentProperties("e:\My Documents\Product Rec
Guidelines.doc")
Console.WriteLine(oFileProperties.Title)
Console.WriteLine(oFileProperties.Author())
Console.WriteLine(oFileProperties.Comments)

oFileProperties = Nothing
oFilePropReader = Nothing

Don't know. I suppose they could have added an interface for structured storage files.

I tried that and I still get the same error. I even tried coping dsofile.dll
to the bin folder but with no luck. Can something else be different??

Did you register DSOFile.dll using Regsvr32.exe or another utility? It is a COM-based component and
needs to be registered before you can use it.

DSOFile.dll was registered with regsvr32. I have been using it in my ASP
pages without any problems...
For .NET, would DSOFile.dll also need to be located in the BIN folder of my
web app?

No location shouldn't matter as long as it is registered, but I think you might need the interop
assembly that was created for it (Interop.DSOleFile) when you distribute the application. Are you
having this problem on your development machine or your web server? I'm assuming you added it as a
COM reference in your project?

Right now it is only on my development machine. I haven't created a project-
just that aspx file above. Do I have to make a project just to get this to
work??

You don't have to create a project but then you will need to late bind on the DSOFile objects:

'Declare as late bound object
Dim FilePropReader As Object
Dim FileProperties As Object
'Create instance of late bound object
FilePropReader = CreateObject("DSOleFile.PropertyReader")

FileProperties = FilePropReader.GetDocumentProperties("e:\My Documents\Product Rec
Guidelines.doc")
Console.WriteLine(FileProperties.Title)
Console.WriteLine(FileProperties.Author())
Console.WriteLine(FileProperties.Comments)

FileProperties = Nothing
FilePropReader = Nothing

OK- THAT WORKED!
Next Problem - It doesn't seem to release the file- when I reload, I get the
following error: "System.Runtime.InteropServices.COMException: A share
violation has occurred"

Any Ideas?

Thanks- Curtis

Try releasing the DSOFile objects after retrieving the properties from a document:

System.Runtime.InteropServices.Marshal.ReleaseComObject(FilePropReader)
System.Runtime.InteropServices.Marshal.ReleaseComObject(FileProperties)

Hi,
I am also using the DSOFile.dll in my ASP.Net application but when i
try to provide the
filename to DSOFile control as
docProps = propReader.GetDocumentProperties(\\<machine>\<folder>\file)
it does not read it. When I provide the local
machine drive(like E:\Folder\file), it works fine but with
network folder, I get the error: Exception from HRESULT:
0x80030002 (STG_E_FILENOTFOUND).
Can some please tell me how to resolve this issue?
.. I am able to generate a list of files from the network drive using
the DirectoryInfo class (had to add <impersonate identity="true" in
web.config to read the network drive)
Can you please tell me if we can read the doc properties from network
drive?
Thanks,

I think the UNC path should work, however, the account under which the ASP application is running
must have read permissions to the UNC resource. If you need to supply a user ID and password when
you create the mapped drive resource then this is likely the problem.

Thanks Paul, I have mapped the drive on which "everyone" has read
permissions. It maps the drive using the windows logon information
which will be my domain account and thus does not prompt for un/pwd.
I am able to generate a list of files from this mapped drive using the
DirectoryInfo class of .Net, so the application reads the drive. But,
the DSOFile control does not read the file. I think the DSOfile works
in Windows shell namespace and cannot utilize the ASP.Net application
identity, but i am not sure..

You might want to try the Process Explorer utility to see where DSOFile is being loaded:
