Delphi:Delphi实现登录窗体说明:本窗体为程序的登录窗体, 其并不由程序自动创建, 详见菜单 Project -> Options -> Auto-ceate Form ，在ShowLoginForm()中创建/使用/关闭/释放。登录窗体调用方法, 使用这个方法可以减少调用处的代码量, 也方便统一的对该窗体进行操作，因为需要查询数据库, 故引用DataModule的单元。关联按钮的Action属性到对应的Action对象上, 按钮会从Action对象中获取一些属性, 如Caption等。窗体释放时, 别忘记关闭Dataset, 或者直接关闭数据库连接, 下面两个Close有什么不同, 请自己思考。
-Delphi: Delphi achieved Login Form Descr iption: This form login form for the program, it does not automatically created by the program, see the menu Project-> Options-> Auto-ceate Form, ShowLoginForm () in creating/using/off/release. Login Form calling methods, using this method can reduce the amount of code to call at, but also facilitate unified operation of the form, because of the need to query the database, it cited DataModule units. Action attributes associated with the corresponding button on the Action object, the button will get some properties from the Action object, such as Caption, etc. When the form is released, do not forget to turn off Dataset, or directly close the database connection, the following two Close any different, please think for themselves.
