structure using dll

[gennady cherkashinin]

Hello all,
does anyone know how to operate on the structure in LABVIEW?
I need to develope the interface in LabVIEW to call the external code WinMCL Plus (developed by GSI Lumonics),
but I do not know how to operate on the global parameter sets. I try to use DLL to call the function
"MC_set _ParamSet" (see below), but I cannot point to the parameter sets in the "Call Library Function".

MC_set_ParamSet
//         Routine Description:
//                     Set the global DLL Parameter set at Params[Index] to
//                     the values stored in *p
//
//         Parameters:
//                        Index - Parameter set index.
//                        *p             - Pointer to the parameters to set.
//
//          Return Value:
//                        WMCL_OPERATION_OK or WMCL_OPERATION_FAILED.
//
//           Comments:
//
WINMCL32_SPEC unsigned long_stdcall MC_set_ParamSet(int Index, PSET *p);


Any help would be greatly appreciated. Thanks in advance for your help.

Gennady,

Check out this link to get some more info...

https://www.ni.com/docs/en-US/bundle/labview/page/configuring-the-call-library-function-node.html

Near the bottom of this link it has the section ;

Calling Functions That Expect Other Data Types

It looks like your best solution would be to create a wrapper that splits up this structure into more basic elements for labview.  Hope this helps.

Hi Gennady,

I'm starting to work with the same WinMCL plus and LabView.Have you just developed some VIs that can be used to mark and set the card ?

Thanks in advance
