How can I make DLL calls to Vision Functions in my .NET Program?

[leq_82]

Hi,All

I want to use VB.NET 2005 to do a vision acquisition,but the carema that I use  is USB carema and Measurement Studio doesn,t support it.

As far as I know,The only way that I can make it is making a dll in LabView and calling it in VB.NET2005,but I don't know how to do it.I hope you

can tell me ,many thanks!

You can contact camera vendor for driver.

Well,I have installed IMAQ for USB Camera1.1 and I have debugged the usb carema in LabVIEW8.20,It's works perfectly,so ,I think it

has no relation with the driver.Any seggestions?

It is nice hearing you use IMAQ-USB. Refer the link for create DLL in LabVIEW http://zone.ni.com/reference/en-XX/help/371361B-01/lvhowto/building_a_dll/
