Creating a DLL in Labview 8.6 and calling it from Visual Basic 6.0

[J.J]

Dear friends,

I need to create a DLL in Labview 8.6 and call it from Visual Basic 6.0. The system works as follows:

I made an application using Labview 8.6 + Vision Assistant 8.6 where I can obtain the x,y coordinates of a template in an certain image being captured by an USB camera. The template coordinates change every time it moves and Visual Basic 6.0 must read these x,y values in real time. I found some information in the link http://zone.ni.com/devzone/cda/tut/p/id/3925, but it works for version 6.x of Labview and 8.6 version is different. Am I in the right path? If you have an updated tutorial like the one in the link above but for Labview 8.6 It would be very nice. Please help me.

Kind regards.

Hello Osvaldo,

I analysed the updated tutorial you sent me, but the thing is that it doen't show how to create the DLL in LV 8.6 but only show how to accessing the DLL from VB6. My problem is really HOW TO CREATE THE DLL IN LV8.6. In the link http://zone.ni.com/devzone/cda/tut/p/id/3063 there is detailed information about how to do this in LV6.x, the problem is that I don't find the path Tools»Build Application or Shared Library (DLL) in LV8.6, I think the procedure in LV8.6 is a little bit different. Don´t you have an updated tutorial on how to build a dll in LV8.6?How could you help me?

Kind regards.

I've been looking for something similar... I need to write a labview DLL for access by C++.  But I'm having difficulty finding resources that really explain the process.  I'm hoping NI will consider upgrading their tutorials... (hint, hint).
