從另一個獲勝形式調用一個獲勝形式

Question

我有2個使用託管C++構建的獲勝形式。在按下一個按鈕時，應該從Client.h中打開另一個表單（login.h），但是我收到錯誤，如「錯誤C3673：'SenderApp :: Login'：類沒有複製構造函數」。

下面是login.h代碼：

我想是這樣Login lgn = gcnew Login();

我知道這個問題是真的老了，但我發現有同樣的問題是，這是沒有任何幫助，所以，當我發現我的解決方案，我想我應該張貼它...

您不必執行一個拷貝構造函數，你可以只使用一個指針，即 -

Login^ lgn = gcnew Login(); 
lgn->Show();
