Re: MDL using C++code convert to .mke file etc.

Hello sir Yongan,

I tried to run HelloWorld. May I know the output for this? As far as I understand, this will scan for linear elements, however when I tried to run this app nothings happen.  Maybe because of the line of code below?:

// The scanning function that does most of the work

int ScanForLinearElements (DgnModelRefP modelRef)

{

   UShort              typeMask [6];

   ScanCallBackData    data;

   data.nElements = 0;

   ScanCriteriaP criteria = mdlScanCriteria_create ();

   mdlScanCriteria_setModel (criteria, modelRef);

   // Tell the scanner to call our function for each element found

   mdlScanCriteria_setReturnType (criteria, MSSCANCRIT_ITERATE_ELMREF, FALSE, TRUE);

   mdlScanCriteria_setElemRefCallback (criteria, ElementRefScanCallback, &data);

   // Tell the scanner we're interested only in certain types of element

   // See mselems.h for the TMSK0_ macros

   memset (typeMask, 0, sizeof (typeMask));

   typeMask[0] = TMSK0_LINE | TMSK0_LINE_STRING;

   mdlScanCriteria_setElementTypeTest (criteria, typeMask, sizeof (typeMask));

   // Execute the scan

   mdlScanCriteria_scan (criteria, NULL, NULL, NULL);

   mdlScanCriteria_free (criteria);

   return data.nElements;

}

Please advice. Can I modify this code to scan for LineString elements and see the result like msgbox that it counts the line string. Thank you.

Best Regards,

Aldrin
