            btnLog.Text = btnLogin;

            this.Controls.Add(TBOX);
            this.Controls.Add(PBOX);

            this.Controls.Add(lblPass);

            this.Controls.Add(btnLog);

            TBOX.Location = new Point(59, 39);
            PBOX.Location = new Point(59, 77);

            lblUName.Location = new Point(18, 42);

推荐答案

您是否在代码中注意到了这一点。

Hi,
Have you noticed this in your code.

TextBox TBOX = null;
TextBox PBOX = null;
Label lblUName = null;
Label lblPass = null;
Button btnLog = null;

你没有''初始化控件，你在构造函数中初始化它们，所以它不会出现在你的设计器中。



顺便提一下你需要查看C＃命名约定

你的命名习惯很糟糕。



问候

Jegan

you haven''t initialized the controls, you are initializing them in your constructor, so it will not show up in you designer.

By the way you do need to look up on the C# naming convention

Your naming habit is terrible.
