vb.net微信消息 vb如何弹出消息框

vb.net中SendMessager的问题

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As String, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As String) As Long

改为

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As String, ByVal wMsg As integer, ByVal wParam As integer , ByVal lParam As String) As integer

再试试，

可能你的声明使用vb6。0 复制过来的，long 全部改成integer

Q3: 请问VB.NET 如何利用PostMessage 向窗口的指定Edit发送信息

你不用程序的情况能不能用TAB切换焦点。如果这样不行的话你用程序控件是没用的。

或都直接对第二个编辑框发送消息。
