Bruce,

It looks like the DeleteLayer support for the shapefile driver was added
for 1.6.0.  So you need to either upgrade or perhaps just delete the files
yourself with unlink().  Make sure the datasource is closed when you do so.

Best regards,

Mateusz:
  Thanks for your reply.  Unfortunately I can not get far enough to do
that.  The crash is occurring down stream from OGRRegisterAll.  That is
to say, the last call in my code space before the crash is
OGRRegisterAll. I can not get OGR initialized to be able to open a data
source.


Bruce,

Are you saying that you are unable to run this simple program successfully?

#include ogrsf_frmts.h
int main()
{
OGRRegisterAll();
}

If you indeed can not run it, it probably means your GDAL installation
is not configured properly or broken.

[gdal-dev] How to delete shapefile

2009-06-16 Thread Clay, Bruce 
I am trying to delete a temporary shapefile after running a process with
the following code.

 

int GdalWrapper::DeleteDataset(const char *datasetName)

{

  int status = -1;

 

  if (datasetName != NULL)

  {

OGRDataSource *dataSrc = OpenDatasetFile(datasetName);

if (dataSrc != NULL)

{

  try

  {

int refCnt = dataSrc-GetSummaryRefCount();

if (refCnt  0)

{

  dataSrc-Release();

}

int deleteOk =
dataSrc-TestCapability(ODsCDeleteLayer);

if (deleteOk == TRUE)

{

  dataSrc-DeleteLayer(0);

  status = 0;

}

else

{

  mLastErrorMsg = Can not delete requested
dataset;

}

  }

  catch(...)

  {

mLastErrorMsg = Could not delete layer: ;

mLastErrorMsg += datasetName;

  }

 

}

 

  }

 

  return(status);

}

 

The TestCapability always returns FALSE.  If I call DeleteLayer anyway I
get an unsupported operation error messege.

I am using GDAL 1.5.3 with Visual Studio 2005.

 

Is there an error in my code or a different way to delete a shapefile
using GDAL or do I have to go to the operating system and find all of
the files that make up the shapefile and delete them that way?
