ADOX 2.7

Create Method Example (VC++)

The following code shows how to create a new Microsoft Jet database with the Create method.

// BeginCreateDatabaseCpp
#import "c:\Program Files\Common Files\system\ado\msadox.dll" no_namespace
#import "c:\Program Files\Common Files\system\ado\msado15.dll"

#define TESTHR(x) if FAILED(x) _com_issue_error(x);

#include "iostream.h"
#include "stdio.h"
#include "conio.h"

//Function declarations
void CreateDatabaseX(void);

//Purpose:  Test Driver
//------------------------------------------------------------                                       //
void main()
{
   HRESULT hr = S_OK;

   hr = ::CoInitialize(NULL);
   if(SUCCEEDED(hr))
   {
      CreateDatabaseX();

      //Wait here for the user to see the output
      printf("Press any key to continue...");
      getch();
      
      ::CoUninitialize();
   }
}

//------------------------------------------------------------                                       //
//CreateDatabaseX                        
//Purpose:  create a new Jet database with the Create method
//------------------------------------------------------------                                       //
void CreateDatabaseX()
{   
   HRESULT hr = S_OK;

   // Define ADOX object pointers.
    // Initialize pointers on define.
    // These are in the ADOX::  namespace.
   
   _CatalogPtr m_pCatalog = NULL;

   
   //Set ActiveConnection of Catalog to this string
   _bstr_t strcnn("Provider=Microsoft.JET.OLEDB.4.0;"
            "Data source = c:\\new.mdb");
   try
   {
      TESTHR(hr = m_pCatalog.CreateInstance(__uuidof (Catalog)));
      m_pCatalog->Create(strcnn);

   }   

   catch(_com_error &e)
   {
      // Notify the user of errors if any.
      _bstr_t bstrSource(e.Source());
      _bstr_t bstrDescription(e.Description());
        
      printf("\n\tSource :  %s \n\tdescription : %s \n ",(LPCSTR)bstrSource,(LPCSTR)bstrDescription);

   }

   catch(...)
   {
      cout << "Error occured in include files...."<< endl;
   }

}
// EndCreateDatabaseCpp
