Calling a COM-Server from a ISAPI-WebModule

I work with an IIS-Webserver, who uses an  ISAPI-application, written in
Delphi. This works.
From this ISAPI-DLL I call a COM-Server. This doesn't work!
First I got the message "CoInitialize not called". I implemented this call.
Now I get the error "Initializing of DLL C:\WINNT\System32\user32.dll
failed"

Some ideas?

Thanks
Bernd

Re:Calling a COM-Server from a ISAPI-WebModule


When making COM calls from ISAPI, follow this pattern:

proc CallCOM;
var
  Foo: IFoo;
begin
  CoInitialize (nil);
  Foo := CoFoo.Create;
  Foo.CallMethod;
  Foo := nil;
  CoUninitialize;
end;

Re:Calling a COM-Server from a ISAPI-WebModule


Thats exactly the way the program works. Yesterday I learned that the
user32.dll-failed message is a known problem with NT. Now I'm looking for a
workaround...

Thanks
