Fields

Name	Value	Description
OK	0	The dialog return value is `OK`. This value typically indicates that the user confirmed the account properties and pressed the `OK` button to close the dialog.
UseSystem	1	Install the service with a system account rather than a user account. This value typically indicates that the dialog was not displayed to the user. For example, the Account property is set to something other than `User`.
Canceled	2	The dialog return value is `Canceled`. This value typically indicates that the user canceled out of the dialog without setting the account fields.

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;

            }

               break;
            }
         }
      }
      while (  !accountSet );

      return accountSet;
   }

public static bool GetServiceAccount(ref ServiceProcessInstaller svcInst)

                                     MessageBoxButtons.OKCancel,
                                     MessageBoxIcon.Hand);

            {
                // Break out of loop.

            }
        }
    } while (!accountSet);

    return accountSet;
}
