自定义登陆窗口

虽然本平台集成了一个现成的用户登陆界面，但是绝大多数人开发系统都是希望有一个个性化的登陆界面的，这样子显得有特色。我们平台中允许用户创建自己的用户登陆界面。理论上我们只需要在项目事件BeforeOpenUserLoginForm中，将e.LoginForm赋值一个自己自定义的登陆窗体即可。

理论上这个登陆窗口用户是可以随意设计的，但是为了配合我平台中一些常规数据的加载，最好还是在我提供的Demo基础上作修改，这样既省心，又可以作扩展，还可以做界面的自定义美化。

第一步，先根据示例，自定义一个窗体。

第二步，给各个控件写事件代码。

            SysLogin.FormAfterLoad(txtUser,chkUser,btnCancel,picBigLogo,this.SmForm);
        }
        
    }
}

第三步，在项目事件BeforeOpenUserLoginForm中，将e.LoginForm赋值一个自己自定义的登陆窗体即可。
