Create Method Example (VC++)
The following code shows how to create a new Microsoft Jet database with the Create method.
// 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;
}
}
