visual basic and cvi

[arnaud2404]

Hi,
I have to use Labwindows/CVI in order to do an automatic test bench.The component tested is controlled by an other software in Visual Basic. How can I control the Visual Basic software with Labwindows. Maybe with dll from VisualBasic but I don't know how to do. Please, help! Thanks in advance. Arnaud2404

Hi Arnaud,

If you need to call VB functions from a LabWindows/CVI application to control the tested devices then you need to create a VB DLL that you will call from LabWindows/CVI. As VB DLLs expose their functions in a particular way, you can't call them directly from LabWindows/CVI and you will need to create an ActiveX controller.
