请问怎样在delphi4里调用winapi函数锁定，解锁键盘？

您好！谢谢您回答我的问题。<br>&nbsp; 您说的方法我试了，但行不通。并且delphi4中关于SystemParametersInfo函数的文档帮<br>助很少，那4个参数我不知道怎么用。是不是我的问题提得不太清楚？我说的锁定键盘特指<br>不让键盘输入输出，让键盘没有响应。<br>&nbsp; &nbsp;另外，我手头上的WINAPI参考资料少得可怜，能不能发给我一些（如果有的话）或介绍<br>相关下载站点。<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 再次感谢您回答我的问题，请回信。<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; lyang_1<br>········································<br>1.我的理解有误。<br>2.cakk,126.com 有WINAPI参考资料。<br>3.请不要另外再开多帐号。<br>

wjiachun锁的是系统热建,所整个键盘没用.<br>印象中没有这样的api,不过用钩子应该很好写.
