[chenxuexia]

The following code is for reading raster from sde-oracle DB: /////////////////////////////////////////////////////////// BOOL DEM::sdeReadDem(const char *szFileName)
{ GDALRegister_SDE();
 GDALOpenInfo OpenInfo(szFileName , GA_ReadOnly);
 GDALDataset  *poDataset;
 poDataset=SDEDataset::Open(&OpenInfo);.....//poDataset !=NULL, read data sucessfully! SDEDataset *pTempDS=(SDEDataset *)poDataset;
 if(pTempDS)
 {
  delete pTempDS;//Access Violation occured!-------->access violate with SDE.DLL//Directly  deletepoDataset also  lead to violation.
  pTempDS = NULL;
 }
 return TRUE;
}/////////////////////////////////////////////////////////Any approach to resolve it?
