c#如何 实现QQ登陆界面的的小键盘功能？

Question

c#如何 实现QQ登陆界面的的小键盘功能？只是针对的textbox就可以了比如现在textbox 里面的值是 abc 然后 点击按钮a 后 textbox里面的值变成abca....
同时有删除 等功能...

Answer 1

用sendkey这个方法，意思就是说在鼠标点击的时候将点击的键对应的值用sendkey发送到键盘。

Answer 2

不过QQ的我觉得应该不是sendkey,如果是sendkey就会被hook钩到,就不能防盗号木马了.
应该是别的方式.

Answer 4

YES,不过LZ似乎想要软键盘，既然这样的话：
首先，你建立一个FORM，自己做的像个键盘样子，要放很多Button，够你忙乎的。
其次，每隔Button都要响应Click事件，也很夸张，但是你必须要做。
再次，VC中使用setWindowsText()，C#中我就不太清楚了。
