如何在光标处插入文字，就像输入法那样？

RT，知道要用到API函数，可具体怎么实现呢？

是你自己的程序还是别人的程序？
如果是你的程序，你用到什么控件？

[darkwalkertt]

我自己写的程序，目的是想填一些表单之类的，不用控件...

SendKeys.Send("test")

把TextBox1.Handle.ToInt32换成目标控件的句柄

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Integer, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As String) As Integer
    Private Const EM_REPLACESEL = &HC2

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        SendMessage(TextBox1.Handle.ToInt32, EM_REPLACESEL, 1, "aAAAAAk中国")
    End Sub
