Can you please point out what your problem is?
Normally you simply import the COM DLL into Delphi and get a _TLB.pas file which allows access.

Robert,

I haven't worked with any DLL's so what I'm looking for is complete code for using the Adobe IFilter DLL to extract all the text from a PDF file.

I also don't know how to import a COM DLL... I didn't even know you could.

It is called "Component -> Import ActiveX Control"
Simply open the DLL and see what happens.
The CoGlobal.Create call is the start of all access.
It creates a COM object. Call the methods and the application will be started in the background to satisfy your calls.
What the methods really do should be documented. If not experiment.
This works for any COM object.

Highfive Gives IT Their Time Back

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Robert,

Your above comment works for any COM object library "that exposes type library information", which this filter dll does not.

Thus the reason I converted the filter.h (from windows platform SDK) so we would all have the interface definition for IFilter (as well as the error code definitions).
