如何在另一个程序中选择所有？ [英] How to select all in another program?

问题描述

我想通过使用SendKeys选择其他程序中的所有文本。

我为记事本文件做了这个：

I want to Select all a text in another program, by using "SendKeys".
I did it for a Notepad file:

IntPtr appHandle = FindWindow(null, "Untitled - Notepad");
        if (appHandle == IntPtr.Zero)
        {
            MessageBox.Show("Specified app is not running.");
            return;
        }

        SetForegroundWindow(appHandle);
        System.Threading.Thread.Sleep(500);

        SendKeys.SendWait("^a");

但是在我想要选择所有文本的程序中，ctrl + a被认为是其他命令。



我该怎么办？

but in the program that I want to select all its text, ctrl+a is considered for other command.

What should I do?

推荐答案

这取决于其他程序以及它如何响应键盘输入 - 没有系统范围选择所有功能，许多程序不要;甚至有一个 - 或需要一个 - 所以你可以;只是假设你可以做到这一点。

如你所做的那样发送CTRL + A可能会起作用 - 或者它可能什么也不做，或者根据谁编码它完全不同。



在Windows应用程序中没有通用的全选方法，保证适用于所有应用程序。

It will depend on the "other program" and how it responds to keyboard input - there is no "system wide" Select All function, many programs don;t even have one - or need one - so you can;t just assume that you can do this.
Sending CTRL+A as you have done may work - or it may do nothing, or something totally different depending on who coded it.

There is no generic way to "Select All" in a windows application that is guaranteed to work for all applications.
