I have a Labview dll need to call in CVI. but it always shows error.

void __cdecl Idx_RW_Reg(uint16_t Register, int32_t RegLength,
 LVBoolean Data_in[], uint8_t OperationRd1Wr0, TD1Hdl *read_reg_table_in,
 uint16_t PortAddress, TD1Hdl *Table_of_reg_out, LVBoolean ControlFrame[],
 uint16_t *PortAddressOut, int32_t len, int32_t len2);

TD1Hdl *read_reg_table_in:What's this,who can tell me  

typedef struct {
 int32_t dimSizes[2];
 LVBoolean BoolEn[1];
 } TD1;
typedef TD1 **TD1Hdl;

Any help is greatly appreciated.

Thanks.

Hi,

What is your call code?

I advise you to read: Calling a LabVIEW DLL from a CVI or Other C/C++ project
