Hi,

Try this code :

ACHAR* pLayerName = pEnt->layer();
bool   bOK        = ((pLayerName != NULL) && (_tcscmp(pLayerName, _T("wall")) == 0));
if (pLayerName != NULL)
  acutDelString(pLayerName);

if (bOK;)
{
  // Do something...
}

Cheers

Thierry

I'm not sure you can develop C# plugin for AutoCAD on MAC.

There is an ObjectARX SDK for MAC, you should investigate this way.

Sollution using wcsstr() function.

You can use this function instead as it provide you more flexibilty while comparing the strings.

wchar_t temp[] = L"Wall";
for (pBlkTblRcdItr->start(); !pBlkTblRcdItr->done();
pBlkTblRcdItr->step())
{

pBlkTblRcdItr->getEntity(pEnt,AcDb::kForRead);
wchar_t *temp1 = pEnt->layer();
if(wcsstr(temp1,temp)!=NULL)
{
acutPrintf(temp1);
}

}
