AcquiredData Event not fired

[bplatte]

Hi,

I want to write a tool for our peoples for easy calibrating our sensors.

Therefore I must use traditional NI-DAQ, because this drivers are installed on all the calibrating PCs (amount 20)

I use Visual Studio 2005 with C#

Versions:

     Measurement and Automation Explorer: 2.2.0.3010 

     AxInterop.CWDAQControlsLib    1.4.0.0

     NI-DAQ-Version   6.9

     Visual Studio 2005 with C#

Problem:

The downloaded samples doesn't running on my PC before (using the exe) and after new compiling they doesn't running too.

Please look at the attachment, its the little project.

Question: the parameter for the method "AquireData" of CWAI1 object is an object (Object browser), it must be an ref type, but a  

object data1 = new object();

object data2 = new object();

CWAI1.AcquireData(ref data1, data2);

erros with a type error, why?

What type should it be?

1.) What is wrong, why don't the event firing? (is "firing" the right word?)

2.) Which types must be used in AquireData-method?

I hope You can help me

Sorry for my bad english

Thanks

Hi!

Try using:

object data1 = null;
object data2 = null;

CWAI1.AcquireData(ref data1, ref data2);

So it should work. The object cannot be already used or refernced before, in those cases it could bring a "Type Mismatch" error.

Best regards.
