Create メソッドの例 (VC++)

次のコードは、Create メソッドを使用して新しい Microsoft Jet データベースを作成する方法を示しています。

// BeginCreateDatabaseCpp.cpp  
// compile with: /EHsc  
#import "msado15.dll" rename("EOF", "EndOfFile")  
#import "msadox.dll" no_namespace  
  
#define TESTHR(x) if FAILED(x) _com_issue_error(x);  
  
#include "iostream"  
using namespace std;  
  
// Function declarations  
void CreateDatabaseX(void);  
  
int main() {  
   HRESULT hr = S_OK;  
  
   hr = ::CoInitialize(NULL);  
   if (SUCCEEDED(hr)) {  
      CreateDatabaseX();  
      ::CoUninitialize();  
   }  
}  
  
// Create a new Jet database with the Create method  
void CreateDatabaseX() {  
   HRESULT hr = S_OK;  
  
   // Define ADOX object pointers, initialize pointers. These are in ADODB 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);  
      printf("Database 'c:\\new.mdb' is created.\n");  
   }  
   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 occurred in CreateDatabaseX...." << endl;  
   }  
}
