How to connect to a personal geodatabase

Making a connection to a workspace is the foundation to accessing data. This sample will show you how to connect to a personal geodatabase stored in an .mdb file. The example code is a function that takes the path to the personal geodatabase as a string and returns a workspace.
 

How to use

  1. Paste the function in your project.
  2. Call the function from your code.
[VCPP] 
//
// openAccessWorkspace:  connect to a personal geodatabase
// connString should be full path to the access database with .mdb extension
// example "c:\temp\geodata.mdb"
//
HRESULT openAccessWorkspace(BSTR connString, IWorkspace **outWorkspace)
{

  HRESULT hr;
  CComPtr < IWorkspaceFactory > ipWorkspaceFactory;
  ipWorkspaceFactory.CoCreateInstance(CLSID_AccessWorkspaceFactory);

  return ipWorkspaceFactory->OpenFromFile(connString, NULL, outWorkspace);
}
