How can I implement the WM_MOUSEHWHEEL message in the tilt wheel mouse in Win200/XP DDK? [Copy link]

In Vista, there is a mouse message WM_MOUSEHWHEEL, but in 2000/XP there is no such message. I want to write a mousefilter to support this function in 2000/XP. How can I do it? In MouseServiceCallback()? I don't know how to implement it in the MOUSE_INPUT_DATA structure.

I worked on it all night yesterday, but still couldn't get it right. According to the description in MSDN, void MouseFilterDevice::MouseServiceCallback( PMOUSE_INPUT_DATA InputDataStart, PMOUSE_INPUT_DATA InputDataEnd, PULONG InputDataConsumed) { t << "ButtonData: " << InputDataStart->ButtonData << EOL; ////Output data display t << "ButtonFlags: " << InputDataStart->ButtonFlags << EOL; ////Output flag display} The data obtained is all 0x0000, which should be 0x020E according to MSDN. The corresponding 0x020A under ButtonFlags is MOUSE_WHEEL, but the actual result is 0x0400. The corresponding 0x020E under ButtonFlags is MOUSE_HWHEEL, but the actual result is 0x0000. Why is ButtonFlags What if Flags and ButtonDara corresponding to MOUSE_HWHEEL are all 0x0000? No one replied, check it yourself!

What other variables are included in the InputDataStart structure besides ButtonData and ButtonFlags? I think the wheel function is not implemented in the button.
