passing pointer to a dll

[Mathan]

Dear champs,

This is my requirement.

   I have five U8 inputs. The address of first data should be passed in as input to a dll. Show me some screenshot of how to establish it.

Thanks,

Mathan

Hi mathan,

create an input argument with type "array", datatype "u8" and array format "array data pointer". Connect your array to the input. I hope this helps.

Dear mike,

So what i have to declare in the dll parameter tab for that input? is it array data pointer?

If so will it take the address of first data?

Thanks,

Dear mike,

Shall i use cluster to pass the values? I saw somewhere on forums but unfortunately, not able to fully read about it.

Hai mike,

I tried both the way. But its showing some problem with dll.

While running with highlight execution it shows some 1097 error when execution crosses CLN block.

How to proceed further? Is it re-traceable?

Thanks,

Mathan

Hi mathan,

did you try it with the array of u8 and "array data pointer"?

What is your function prototype? What does the function do?

You may want to take a look at the example "Call DLL" that ships with LabVIEW. Help->Find Examples, then search for "DLL".
