Hi,
So the dll problem is for me I have a driver that I access through dll
provided with the sdk (Microscope toolBox for Zeiss Axiovert 200M).
There is definitely nothing done for labview in this SDK. So This one
usually crashes labview itself probably accessing memory in a wrong
location. Moreover loading the dll through opening the VI before
sending the afxOleInit make this problem worse! There is of course the
way to load dll through a piece of C code (LoadLibrary function),
nevertheless, I am not fond of writing this. So some part of this dll
are under the form of ActiveX (unfortunately non documented) so I open
one of these, forcing in this way the afxOleInit() then I load the
SubVI in Vi Server and execute it. The dll called by the subVI are
loaded only at the time I load dynamically the SubVI (according NI
doc); of course if I call the subVi in the usual way, everything is
loaded when the top (main) Vi is loaded. I assume that when I close the
refnum related to the subVI, dll are unloaded, but I'm not sure and I
don't remember any statement about such a point in the doc. There is an
exemple in the doc of Labview 7.1.1 about doing that.
Of course I tryied to add my subMain.VI as dynamically loaded Vi in the
builder, but then it does not add automatically the SubVIs of SubMain
(I can build but executing SubMain fails). I use version 7.1.1 Which
version are you using to allows subVis to be loaded? Or is it an option
I have to switch to have the proper behaviour?
Thanks in advance for the help
