Kann jemand diese C++ Code in C# schreiben

[basrix]

Hallo,

ich muss für ein Intranet Programm auf eine fremde Datenbank zugreifen und Infos reinschreiben. Ich habe eine C++ Beispiellösung gefunden, aber habe keine Ahnung von C++. Ich habe gerade mit c# angefangen.

Kann jemand mir helfen folgendes Beispiel in C# umzusetzen. DANKE IM VORAUS!
Example 1: Creating a new user account
As an example, we will try to insert a new user ”mary” into OmniTracker’s database.

• Create a new dialog-based project using the ”MFC AppWizard (exe)”.
  
  Add a button called ”Add User” to the dialog.
• Assign a handler OnAddUser() to the button, and fill it with the following code:

IOtApplicationPtr pApp;
 
HRESULT hr = pApp.CreateInstance(__uuidof(OtApplication), NULL,
CLSCTX_INPROC_SERVER);
 
if (FAILED(hr))
{ 
CString str;
 
str.Format ("CreateInstance() failed: 0x%08lx",
(ULONG) hr);
AfxMessageBox (str);
}
 
try { 
IOtSessionPtr pSession;
 
pSession = pApp->MakeSession("hostname", 4567"superuser", "password");
 
IOtUsersPtr pUsers;
pUsers = pSession->Users;
IOtUserPtr pUser;
pUser = pUsers->Add();
pUser->LoginName = "mary";
pUser->EmailAddress = "mary@company.com";
pUser->Password = "65gh45";
pUser->DisplayName = "Mary";
pUser->Save();
} catch(_com_error& e) {
_bstr_t bstrDescription(e.Description());
AfxMessageBox((LPCTSTR) bstrDescription);
}

• At the top of the file containing OnAddUser(), add the following line:

import "otaut.tlb" no_namespace
This imports the definitions from the OmniTracker Automation interface.

• Make sure, that the OmniTracker installation directory is part of the list of the C++ preprocessor ‘s include directories.
• In the InitInstance() routine of your application, initialize COM by including the following lines:

HRESULT hr = CoInitialize(NULL);
if (FAILED(hr))
{
AfxMessageBox ("Cannot initialize COM!");
return FALSE;
}

• Compile and link the source files, and execute the program.
