Word文件滚动位置 [英] Word File scroll position

问题描述

有人知道如何从C ++应用程序获取和设置正在运行的Word文件的滚动位置吗?例如，我在程序中使用Shellexecute调用运行Word，但是我想恢复文件中的最后一个已知滚动位置.

Does anyone know how to get and set the scroll position of a running Word file from a C++ application? For example I am running Word using a Shellexecute call in my program but I want to restore the last known scroll position in the file.

推荐答案

您可以尝试发送 SBM_SETSCROLLINFO [ FindWindowEx [ SBM_GETPOS [

You could try sending the SBM_SETSCROLLINFO[^] message directly to the scroll bar control in Word. The vertical scrollbar should have the caption "Vertical". You can use FindWindowEx[^] to find the vertical scrollbar if you have the parent handle. I believe you can call SBM_GETPOS [^] to get the current position of the scroll bar.

回答第二个问题:

例如，使用Word应用程序的父句柄(parent_hwndN)，可以尝试以下操作:

To answer your second question:

For example, using the parent handle (parent_hwndN) for the Word application, you can try this:

vscr_hwnd= FindWindowEx( 
parent_hwndN,
NULL,
"NUIScrollbar",
"Vertical",
);

感谢您的回复.我确实有父句柄，但是在使用FindWindowEx时遇到了麻烦.这是获取垂直滚动条的正确形式吗?

vscr_hwnd = :: FindWindowEx(
parent_hwndN，
NULL，
垂直"，
NULL
);

Thanks for your response. I do have the parent handle but I am having trouble w/FindWindowEx. Is this the proper form to get the vertical scrollbar?

vscr_hwnd=::FindWindowEx(
parent_hwndN,
NULL,
"Vertical",
NULL
);
