Page turning function based on Windows API keyboard event

[jiamingl24063286]

I would like to achieve Page Turning function for an opened PDF, based on Windows API keyboard event, however I've tried:

//Turn page up

HWND hWnd = ::FindWindow(NULL, _T("xxx.pdf - Adobe Acrobat Reader DC"));

HWND hWnd_c = ::FindWindowEx(hWnd,0,_T("AVL_AVView"),NULL);

int ret = ::PostMessage(hWnd_c, WM_KEYDOWN, VK_PRIOR, 0);

int ret2 = ::PostMessage(hWnd_c, WM_KEYUP, VK_PRIOR, 0);

However it didn't work, and I'd like to solve this issue.

I have tried push "F1" in same method and it works, but push "PageUp" still doesn't work.

Are you viewing the first page already?

Certainly I've focused on center page.

Try the Acrobat SDK forum.

Since I know the Acrobat SDK​ mainly do operation towards pdf file, but I don't know whether could receive PC's keyboard message?

This is not covered in the SDK. The SDK is mainly about automating Acrobat, not Reader. Adobe will not want automating the free software to work of course!

And by the way, try all the windows and child windows. Remember that because of sandboxing there may be multiple ACRORD32.EXE processes; it's also possible that your messages are blocked by the sandbox.

I have checked the security setting, my Acrobat Reader's Protected Mode is off, so I think it's not caused by sandbox.
