This is the code:

typedef struct {	LStrHandle SerialNumber;	LStrHandle ModelName;	LStrHandle FullName;	LStrHandle VendorName;	LStrHandle DeviceClass;	LStrHandle DeviceVersion;	LStrHandle UserDefinedName;	} CamInfoCluster;typedef struct {	int32_t_Dilas dimSize;	CamInfoCluster CamInfo[1];	} CamInfoArray;typedef CamInfoArray **CamInfoArrayHdl;//DT1Hdltypedef struct {	LVBoolean status;	int32_t_Dilas code;	LStrHandle source;	} ErrorCluster;void EnumerateCameras(CamInfoArrayHdl CamArray, ErrorCluster *LVError){	int numDevicesAvail;	char* String;	numDevicesAvail = 3;	int deviceIndex;	MgErr err = mgNoErr;	if( mgNoErr == (err = DSSetHSzClr(CamArray, Offset(CamInfoArray, CamInfo) + sizeof(CamInfoCluster)*numDevicesAvail)) )	{  	(*CamArray)->dimSize = numDevicesAvail;  	//Initialize new elements????? (Example please)   	}	else	{		FillErrorCluster(LVError, TRUE, mFullErr, "mFullErr");		return;	}	for ( deviceIndex = 0; deviceIndex < numDevicesAvail; ++deviceIndex )	{		String = "Serial";		//SerialNumber		(*((*(CamArray))->CamInfo[deviceIndex].SerialNumber))->cnt = strlen(String);		NumericArrayResize(uB, 1, (UHandle*)(&((*(CamArray))->CamInfo[deviceIndex].SerialNumber)),				       4 + (*((*(CamArray))->CamInfo[deviceIndex].SerialNumber))->cnt);				strncpy((char*)(*((*(CamArray))->CamInfo[deviceIndex].SerialNumber))->str, String, (*((*(CamArray))->CamInfo[deviceIndex].SerialNumber))->cnt);	} }void FillErrorCluster(ErrorCluster *LVError, LVBoolean bStatus, int iCode,char* cSource){	LVError->status = bStatus;	LVError->code = iCode;	(*(LVError->source))->cnt = strlen(cSource);	NumericArrayResize(uB, 1, (UHandle*)(&(LVError->source)),			  	4 + (*(LVError->source))->cnt);	strncpy((char*)(*(LVError->source))->str, cSource, (*(LVError->source))->cnt);}

The incoming Array can be empty!

LV Error:

Possible reason(s):

LabVIEW: An exception occurred within the external code called by a Call Library Function Node. The exception may have corrupted LabVIEW's memory. Save any work to a new location and restart LabVIEW

Thanks Adam for your great TUT "interfacing a DLL specifically made for LabVIEW".

Everything works fine, but If I try to change the new element without Initialising, the DLL throws an error.

How can i initialize the new element?

Can you give me short example for my application?

I have an Array of Clusters with 2 Strings.
