How to convert VB.Net NiDAQmx code to VB6 NiDAQmx code?

Hello,

The reason you are not getting anything returned is because the string is not initialized to a certain length before it is returned.  Basically, the function that you are calling returns a pointer to a string but doesn't return the length of the string. If you use the following code it should work correctly:

Dim sDevices As String *50

Dim IReturn As Long

IReturn = DAQmx(GetSysDevNames(sDevices, 256)

MsgBox(sDevices)

This should now show you the devices you have on your system and should have a return code of 0. Have a great day!

Adam,

That worked.Thanks. Been awhile since I did any VB6... I'm looking for one other function from .Net NiDAQmx... Can you tell me what the equivalent of:

DaqSystem.Local.LoadDevice(sDAQDevice).DeviceID

Thanks!

Hello,

I don't know if there is an exact function that will do what the .NET one does, but I believe this one is pretty close: DAQmxGetDevProductType.
