Re: Sending Key messages to a Windows App

New Message on dotNET User Group Hyd Sending Key messages to a Windows App Reply   Reply to Sender   Recommend Message 5 in Discussion From: Mahendrakumar8 yeah, we can do that, send messages to other/third party windows application. For this, we need to have the handle to the control where you want to send the message. In windows, all the child controls have handles with them and we need to know them. once we know the handle, then we need to import the win32 api call by using DllImport attribute and import SendMessage api call. And in our program, we should passon the handle to the control, along with the message. Sample Code : using Microsoft.Win32; [DllImport("user32")] public static extern int SendMessageA(int handle, int command, int instruction, StringBuilder str) My_Method() { //get the handle to the destination window/control SendMessageA(handle, WM_NOTIFY, CMD, null); } Handle -> Destination window Handle CMD -> It's enum. KeyDown, KeyUp Thanks & Regards, A. Mahendra kumar View other groups in this category.
