如何使用python和win32 api将颜色文本写入文本框？ [英] How can I write color text to a textbox using python and the win32 api's?

问题描述

基本上我想使用python将彩色文本写入另一个应用程序的文本框窗口。

Basically I want to write colored text to a textbox window of another application using python.

一般的想法是：

win32gui.SendMessage( hwnd, EM_SETCHARFORMAT, SCF_SELECTION, format);

其中format是 CHARFORMAT 。

我的问题是EM_SETCHARFORMAT和SCF_SELECTION

My problem is that EM_SETCHARFORMAT and SCF_SELECTION are not included in the win32con library (I think) and I am unsure how to create a CHARFORMAT object.

在python中是否可能？

Is this possible in python?

推荐答案

事实证明，这是很难实现的。问题是 EM_SETCHARFORMAT 通过引用传递结构。 EM_SETCHARFORMAT 不是常见的Windows消息之一，它在 WM_USER 范围内。 lParam 指向的内存没有在进程边界之间编组。

It turns out that this is quite difficult to achieve. The problem is that the EM_SETCHARFORMAT passes a structure by reference. The EM_SETCHARFORMAT is not one of the common Windows messages, it's in the WM_USER range. The memory pointed to by lParam is not marshalled across the process boundary. The receiver of the message receives a pointer to memory that is only meaningful in the sender's process.

这意味着你唯一的解决方案是使用 WriteProcessMemory 将 CHARFORMAT 缓冲区写入目标进程中分配的内存块。这是可能的，但相当麻烦，尤其是在Python。

This means that your only solution will be to use WriteProcessMemory to write the CHARFORMAT buffer into a block of memory allocated in the target process. This is all possible but quite cumbersome, especially in Python.

如果我是你，我会考虑一个替代解决方案你的问题。

If I were you, I would consider an alternative solution to your problem.
