Hallo,
Habe jetz aber weiter gesuch und folgenden source gefunden:
| C++: |
#include "stdafx.h"
// BeginProcedureParametersCpp
// ADO COM Komponente einbinden (-> steckt in der DLL msado15.dll)
#import "C:\Programme\Gemeinsame Dateien\System\ado\msado15.dll" rename("EOF","ADOEOF")
// #import "msado15.dll"
#import "C:\Programme\Gemeinsame Dateien\System\ado\msadox.dll" no_namespace
// #include "iostream.h"
#include "stdio.h"
#include "conio.h"
using namespace std;
//Function declarations
inline void TESTHR(HRESULT x) {if FAILED(x) _com_issue_error(x);};
void ProcedureParametersX(void);
//////////////////////////////////////////////////////////
// //
// Main Function //
// //
//////////////////////////////////////////////////////////
void main()
{
if(FAILED(::CoInitialize(NULL)))
return;
ProcedureParametersX();
::CoUninitialize();
}
//////////////////////////////////////////////////////////
// //
// ProcedureParametersX Function //
// //
//////////////////////////////////////////////////////////
void ProcedureParametersX()
{
HRESULT hr = S_OK;
// Define ADOX object pointers.
// Initialize pointers on define.
// These are in the ADOX:: namespace.
_CatalogPtr m_pCatalog = NULL;
//Define ADODB object pointers.
ADODB::_ConnectionPtr m_pCnn = NULL;
ADODB::_CommandPtr m_pCommand = NULL;
ADODB::_ParameterPtr m_pParameter = NULL;
try
{
TESTHR(hr = m_pCnn.CreateInstance(__uuidof(ADODB::Connection)));
//Open the Connection
m_pCnn->Open("Provider='Microsoft.JET.OLEDB.4.0';"
"Data Source='c:\\Nordwind.mdb';","","",NULL);
TESTHR(hr = m_pCatalog.CreateInstance(__uuidof(Catalog)));
//Open the catalog
m_pCatalog->PutActiveConnection(_variant_t((IDispatch *)m_pCnn));
//Get the command object
m_pCommand = m_pCatalog->Procedures->GetItem("Benutzer")->GetCommand();
_variant_t vIndex;
//Retrieve Parameter information
m_pCommand->Parameters->Refresh();
for (long lIndex = 0; lIndex < m_pCommand->Parameters->Count;
lIndex ++)
{
vIndex = lIndex;
m_pParameter = m_pCommand->Parameters->GetItem(vIndex);
cout << m_pParameter->Name << ":" << m_pParameter->Type <<
"\n" << endl;
}
}
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 ProcedureParametersX...."<< endl;
}
}
// EndProcedureParametersCpp
|
Er Kompeliert es und macht die verbindung zur Datenbank.
Aber bei:
| C++: |
m_pCommand = m_pCatalog->Procedures->GetItem("Benutzer")->GetCommand();
|
bricht er ab und sagt das er das Objekt nicht finden kann.
Die Tabelle existiert aber.
Hat dazu jemand eine idee ??
Gruß und Danke
