Imaq refnum c#

[Seb_P]

Hi,

I'm trying to send an image from C# to labview by using Interoperability.

I have a bitmap variable in c# and i want to pass it on labview. But i have to use Imaq and the only way i found is to save this one one hdd, but this solution is very very long...

How can i generate an Imaq from C# and pass it with interop ?

You'll find in attatchment my vi and interop dll.

Thanks a lot.

I'm using LV2012, VS2010 and C#

Hi Seb,

If you're question is about how to use Interoperability with LabVIEW, you'll find several tutorials in the links below that teach you how to do so :

>> Building a .NET Interop Assembly (Windows)

>> How to Add a LabVIEW .NET Interop Assembly to the Global Assembly Cache

>> How Do I Use a LabVIEW DLL in Microsoft Visual Studio.NET?

>> Interoperability (C# Programming Guide)

Was it what you were looking for?

Have a nice day

Hi Marc,

Kind of, yes.

I already know how use generic fonction with interoperability such as Dot product, Multiply, and other.

But my real problem is, how can i use Imaq from C# ? For other function i'm using only simple type like double or array.

In my case, i must save bmp on hdd and load it after, in my LV code... Not really efficient and little long.

Ok it's a different question then. The best method for that would be to use the NI-IMAQ Function Reference Help that you'll find in a place that looks like that : C:\Program Files (x86)\National Instruments\NI-IMAQ\Docs

If the drivers are not yet installed on your computer you can download it from there : NI-IMAQ Function Reference Help

There also are some exemple that may help you and should be installed on your computer : C:\Users\Public\Documents\National Instruments\NI-IMAQ\Examples

I hope this helps,

Have a nice day,

All of exemple in C:\Users\Public\Documents\National Instruments\NI-IMAQ\Examples are very interesting. (unfortunately, no much reference about it on the net)

But i can't find any refnum to use as parameter for an interop function.

Is it in the ImaqSession ?

Thanks a lot.

Mistake 🙂

I'm trying to use Imaqdx; Then ImaqdxSession.
