如何用VB实现向其他程序发送字符或文字?

为了减少重复性的输入,我想用VB编程的方式如何实现向Word或记事本等其他程序模拟键盘发送字符或文字,如中华人民共和国Chinese等等,

另请不要仅仅回复使用如Sendkeys等函数,我想要完整源码学习VB,因我认为此程序需使用API,但我对API一窃不通.多谢

但这些都是声明API，但如何具体应用这些函数呢？即我按一下“CMD”按钮，如何能让此程序向WORD发送“中华人民共和国Chinese”等等字符和文字呢？多谢指教！

多谢“狮儿”的回复：

可能是我写的不清，我的目的减少键盘的手工输入，即先将一些常用字符和文字储存起来，在需向其他程序（不专用于WORD、记事本，还可以是其他如QQ，EXCEL等等程序）输入这些常用字符和文字时，就可以调用这个VB程序来实现输入，免去手工重复地用键盘向其他程序输入字符和文字的无用功。多谢！

楼主的想法实现起来是非常复杂的. 因为QQ已经屏蔽了SendMessage函数, 要使用大没Hook才能写QQ尾巴. 而API Hook已经昌隐远远超出我的知识范围. 就算有高手写出来, 楼主也不一定能看得懂.

而且写这种程序, 还不如直接在某个地方事先输入好常用的语句字符, 然后用键盘复制粘贴(CtrlC CtrlV), 这样也很快捷. 而要写一个所有程序通用的这种输入程序, 还不如用紫光拼音输入法自造词句来得更快, 你说是不是?

我写过, 不过代码不在手头上. 如果你要往WORD里写入东西, 那不是用SendMessage的, VB可以与WORD用接口连接, 用类方法实现这种功能. 如果要往记事本等写入文本, 才用SendMessage. 以下代码用于改变标题为"无标题 - 记事本"的记事本窗口的文本. 注意, 是设置, 而不是追加文本. 我忘了追加文本是用什么消息了. 抱歉.
