I have created a web phone project. When I log in then I get a new window with logout button. My login window has two textboxes. When I log out then I get the login window but the previous information is present in that text box.

推荐答案

如果您的登录表单验证了用户名和密码，则只需在验证后设置myUserIDTextBox.Text = "";等但在关闭/隐藏登录表单之前.

如果登录表单只是将UserID和密码传递给主表单进行验证，则将信息存储在私有成员中，设置textboxes ="，然后使用私有成员将信息传递给主表单.

简而言之，在离开登录表单之前，请确保不再需要文本框的内容，然后清除它们.

If your login form verifies the user and password then simply set myUserIDTextBox.Text = ""; etc after verification but before closing/hiding the login form.

If the login form simply passes the UserID and Password to the main form for verification then store the information in private members, set the textboxes = "", and then pass the information to the main form using the private members.

To put it simply, before leaving the login form, make sure that the content of the textboxes is no longer required and clear them then.

关于答案，亨利写道myUserIDTextBox.Text = "";
如果您使用的是 C ++/clr (即托管的C ++ )，那是正确的.如果您以本机语言编写应用程序，则可以编写myUserIDTextBox.SetWindowText(_T(""));

On is answer, Henry wrote myUserIDTextBox.Text = "";
That''s is right if you are using C++/clr (i.e. managed C++). If you are writing your application as native you can write myUserIDTextBox.SetWindowText(_T(""));
