Hi,

we are about to develop a programm that has to run in an  environment without admin privileges, so we won't be able to register the ActiveX-DLL.

Is it possible to use the non ActiveX-DLL in our VBA-program?

Greeting

Hi Chris!

ActiveX is the better solution but a non-ActiveX-dll works in the described environment, too.
VBA doesn't have problems calling a "normal" dll put the dll in the same directory where your app is and it will work ... and i should know it ;-)
If you need things about how to call please post it here.

Cheers and welcome here,
Ingo

Hi Ingo,

thanks for the answer. Could it be possible to use the ActiveX-DLL without registering it? Or is it better to use the other?

You can't use the activex dll without registering it. You need to use the regular non-actives dll if you are going to. The calling program entry points are different between the 2.

I have worked on for some time.

It is possible to link and load to the standard QPL DLL version but I cannot get strings to pass to and from the library successfully.

I can get VBA to load the standard DLL and calling CreateLibrary seems to work.  Call QP.UnlockKey fails.  I have tried all combinations of ByRef, ByVal, String, Variant ...  using QP.UnlockKeyA ... but the strings returned by QPL are always empty.  It could be because the strings may actually be BSTR's.
