Pass array to "Labview 7" DLL in Visual Basic

[Yabune]

Hi!

I would like to pass arrays in Visual Basic to a LV DLL made in Labview 7.

I've seen the examples of NI to create a dll in Labview for Visual Basic and for passing arrays, but all the examples were made with Labview 6.

The problem is that in the tutorial they say to define the Pass By of the argument as Array Data Pointer, but in Labview 7 when I add an array as an argument I don't have that option.. It's always defined as TD1Hdl* inArray, and in Labview 6 it was defined as float64 inArray[].

Can I use the TD1Hdl structure in Visual Basic? How do I use it?

Thanks!

Hi,

What do you will make :

Call a Visual basic dll in LabView 7 or Call a LabVIEW dll in Visual basic ?

See the link below, they are some information about this,

I want to call a LabVIEW dll in Visual basic but the problem is the link you gave me only works for 1D arrays.

I have in the dll string arrays and 2D arrays of numbers.

And those kind of arrays doesn't let me change the pass by argument, as it is said in your link.

With these arrays it only works as TD1Hdl structure..

How do I use them in VB?

Thanks!

Unfortunately, i'm not expert in Visual Basic, i need to investigate in your problem.

See link below, that explain how you can use LabVIEW DLL in Visual Basic.
