写文本框在另一个进程在Win32中（C ++） [英] Writing to textbox in another process in Win32 (c++)

问题描述

假设你需要编写一个程序或服务（过程1），将读取或写入文本框在另一个应用程序或进程（process 2）。它是如何做？
IS进程2的文本框的名称写在某种注册表，这样我可以从某种系统调用得到它？

Suppose you need to write a process or service (process1) that will read or write to textbox in another application or process (process 2). How is it done? Is the name of the textbox of process 2 is written in some sort of a registry so i can get it from some sort of a system call?

感谢。

推荐答案

文本框是由一个ID号，你可以找到使用间谍++标识。使用FindWindow函数和EnumChildWindows寻找目标文本框的HWND。随着HWND你可以SendMessage函数WM_GETTEXT或WM_SETTEXT。注意：如果两个进程的安全等级不同，这是行不通的。

The text box is identified by an ID number that you can find using Spy++. Use FindWindow and EnumChildWindows to find the HWND of the target text box. With the HWND you can SendMessage WM_GETTEXT or WM_SETTEXT. Note: This won't work if the security level of the two processes differ.
