Dynamically linking a vi to a dll (vi) already loaded by an application?

[Wiebe@CARYA]

Hi,

I have a library for this, if you're interrested. If you're going to search
the forum, search for Wiebe Walstra.

Regards,

Wiebe.

Sorry, Wiebe for getting your last name wrong. I must have been in some
state of confusion here.

Wiebe,

Yeah I would be interested in your library. Does it used memory mapped files (MMF) or some other technique for the shared memory space. Not sure if MMFs are what I'm after. Also looking at the possibility of using DDE.

Thanks

Mike

About halfway into the second link I provided above is his library as
attached ZIP file Test Mapping.zip.

Hi,

you have written that you have a library for the topic "memory mapping" can you tell me where? I have searched in the forum, but I haven´t found anything.

thanks
