模拟键盘我们用Keybd_event这个api函数,模拟鼠标按键用mouse_event函数。大家不用担心,在delphi里调用api函数是很方便的事。
先介绍一下Keybd_event函数。Keybd_event能触发一个按键事件,也就是说回产生一个WM_KEYDOWN或WM_KEYUP消息。当然也可以用产生这两个消息来模拟按键,但是没有直接用这个函数方便。Keybd_event共有四个参数,第一个为按键的虚拟键值,如回车键为vk_return, tab键为vk_tab。第二个参数为扫描码,一般不用设置,用0代替就行。第三个参数为选项标志,如果为keydown则置0即可,如果为keyup则设成“KEYEVENTF_KEYUP”,第四个参数一般也是置0即可。用如下代码即可实现模拟按下i键,其中的$49表示i键的虚拟键值:
keybd_event(VK_F11,0,0,0); keybd_event(VK_F11,0,KEYEVENTF_KEYUP,0); …
mouse_event最好配合setcursorpos(x,y)函数一起使用,与Keybd_event类似,mouse_event有五个参数,第一个为选项标志,为MOUSEEVENTF_LEFTDOWN时表示左键按下,为MOUSEEVENTF_LEFTUP表示左键松开,向系统发送相应消息。第二三个参数分别表示x,y相对位置,一般可设为0,0,第四五个参数并不重要,一般也可设为0,0。若要得到Keybd_event和mouse_event函数的更详细的用法,可以查阅msdn或delphi帮助。
一、简述
记--使用C语言 打开指定网页,并模拟鼠标点击、键盘输入。实现半自动填写账号密码,并登录网站(当然现在的大部分网站都有验证码,或有检测"非人为"操作,以防止恶意注册、登录)。

五、总结
5.1 ShellExecute()函数
功能 | 对指定的文件执行操作。(可以实现调用第三方程序) | |
头文件 | Windows.h | |
原型 | HINSTANCE ShellExecuteA( HWND hwnd, LPCSTR lpOperation, LPCSTR lpFile, LPCSTR lpParameters, LPCSTR lpDirectory, INT nShowCmd ); | |
参数 | hwnd | 父窗口的句柄。如果操作与窗口不关联,则此值可以为空 |
lpOperation | 指定要执行的操作(谓词)
|
|
lpFile | 操作对象(文件等。。。) | |
lpParameters | 如果lpFile指定可执行文件,则此参数是指向以-结束的字符串的指针,该字符串指定要传递给应用程序的参数。此字符串的格式由要调用的谓词决定。如果lpFile指定文档文件,则lpParameters应为空。 | |
lpDirectory | 指定操作的默认(工作)目录。如果此值为NULL,则使用当前工作目录。 | |
nShowCmd |
指定打开应用程序时如何显示的标志。如果lpFile指定文档文件,则只需将标志传递给关联的应用程序。应该由应用程序来决定如何处理它。这些值是定义的。 SW_HIDE:隐藏 SW_MAXIMIZE :最大化 SW_MINIMIZE :最小化 。。。 |
|
返回值 | 如果函数成功,则返回大于32的值。如果函数失败,它将返回一个错误值 | |
