Examples

The following example uses a ServiceInstallerDialog to prompt the user for a service installation account.

   // Prompt the user for service installation account values.
public:
   static bool GetServiceAccount( interior_ptr<ServiceProcessInstaller^> svcInst )
   {
      bool accountSet = false;
      ServiceInstallerDialog^ svcDialog = gcnew ServiceInstallerDialog;

      // Query the user for the service account type.
      do
      {
         svcDialog->TopMost = true;
         svcDialog->ShowDialog();
         if ( svcDialog->Result == ServiceInstallerDialogResult::OK )
         {
            // Do a very simple validation on the user
            // input.  Check to see whether the user name
            // or password is blank.
            if ( (svcDialog->Username->Length > 0) && (svcDialog->Password->Length > 0) )
            {
               // Use the account and password.
               accountSet = true;
               ( *svcInst)->Account = ServiceAccount::User;
               ( *svcInst)->Username = svcDialog->Username;

            }
        }
    } while (!accountSet);

    return accountSet;
