欄位

Canceled	2	對話方塊傳回值為 Canceled。 這個值通常表示使用者取消對話方塊，而沒有設定帳戶欄位。
OK	0	對話方塊傳回值為 OK。 這個值通常表示使用者已經確認帳戶屬性，並且按下 OK 按鈕來關閉對話方塊。
UseSystem	1	以系統帳戶安裝此服務，而非使用者帳戶。 這個值通常表示不會向使用者顯示此對話方塊。 例如， Account 屬性設為 User 之外的其他值。

範例

下列範例會使用 ServiceInstallerDialog 來提示使用者輸入服務安裝帳戶。

   // 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;
