Bob, with any .Net DLL you need to create a COM wrapper for it to let
it be seen by COM based applications. AFAIK this is not a difficult
task, but it does need to be done in Visual Studio. I was always of
the belief that it could be done with the Express versions. So maybe
with VB Express or C# Express you can create a COM wrapper. You might
need to dig through the net a bit and find a custom made project type
that eases the creation process. I did this years ago for creating a
service in VB Express as there was not a project already there for it.
I am sure there will be one around. From memory it was simply a
wrapper class that exposed COM methods and properties for each of
the .Net methods and properties and that was it.

Bob, I think I have the answer for you. See this article:
http://support.microsoft.com/default...b;en-us;317535
This is the clearest explanation I have seen on the topic. It seems
like it is only a compiler option when building the class DLL.

Cheers

I mentioned Lebans code because all he needs is the following code to
use his DLL.

Public Declare Function ConvertUncompressedSnapshot Lib
"StrStorage.dll" _
(ByVal UnCompressedSnapShotName As String, _
ByVal OutputPDFname As String, _
Optional ByVal CompressionLevel As Long = 0, _
Optional ByVal PasswordOpen As String = "", _
Optional ByVal PasswordOwner As String = "", _
Optional ByVal PasswordRestrictions As Long = 0, _
Optional ByVal PDFNoFontEmbedding As Long = 0, _
Optional ByVal PDFUnicodeFlags As Long = 0 _
) As Boolean

Exactly. You declare it just like you do Windows APIs, with a
function for each function provided by the DLL.

Hi Bob,

Did you get this going?

Hi Bob,

Does that mean that the Express versions dont support the necessary
compiler options to achieve this? Can you post the .Net code to me, or
email it to me at the address I use for this NG? I'll see if I can
find a way around the problem.

Hi Bob,

I have had a small brainwave about this topic. I am not sure if it
will work or not, but might be worth a try just the same. Perhaps
instead of needing Visual Studio (not the express versions) you could
try and use Mono (the open source development version). There is the
ability to build and compile .Net code with a Mono IDE (such as
Eclipse perhaps?). It might be worth a look since all you want to do
is compile the thing with a few options set.

Just a thought
