NMS Posted November 3, 2022 Posted November 3, 2022 Hello, To make things short, for various reasons I'm using $WM_NOTIFY (I am aware of $WM_MOUSEWHEEL) to call the function and an event mask to detect multiple changes inside the edit control. However I am having trouble distinguishing scroll up and down. To me it seems like there's just no way to tell the difference between the two within the method that I'm using.

Solution Nine Posted November 3, 2022 Solution Posted November 3, 2022 The wParam member of the $tagMSGFILTER structure tells whether it is mouse wheel up or down (0 or 1).

Expand I'm getting a 0 only from that parameter. Unless I'm missing a step, fairly new to WM commands.

Expand Yeah that's what I've tried earlier. Seems to me like RichEdit has own messages (https://learn.microsoft.com/en-us/windows/win32/controls/rich-edit-control-event-mask-flags) it listens to and that's why I wanted to do it using WM_NOTIFY and event mask so I could have everything under single function for future.

pixelsearch Posted November 3, 2022 Posted November 3, 2022 Glad we could help If you don't mind, I'd like you to change the "solved by pixelsearch" to "solved by Nine", thanks ! "I think you are searching a bug where there is no bug... don't listen to bad advice."
Nine Posted November 3, 2022 Posted November 3, 2022 @pixelsearch That's a nice gesture of you, but was not necessary. Anyway thanks.
