In labview 64bit, Use PostLVUserEvent with user data cluster, unhandled exception occured.

[274130384@qq.com]

My labview is Labview 2009 64 bit, I use PostLVUserEvent to post message with cluster data to labview. The following is  the struct in dll:

typedef struct {
    int32 dimSize;
    uInt8 elt[1];
} TD1DINT8;
typedef TD1DINT8 **TD1DINT8Hdl;

typedef struct{
   int32       interruptSource;
   TD1DINT8Hdl portData;
}DIInterruptData, *PDIInterruptData, **HDIInterruptData;

In labview, the DIInterruptData corresponds to a cluster, in which there are a int32 integer and a uint8 array. 

It works well in labview 32bit. But in labview 64bit, unhanlded exception occured. why?

Hi Danil,

when complaining about double-posts one should provide a link to the other thread to guide other users...
