winapi - WinAPI: Handling the Left mouse double click for supressing the first click?

Question

How can I handle left mouse double click events in Windows by suppressing the first click events.For ex: Left mouse single click highlights the image object and double click zooms the image, but for now I want on double click not to highlight the image object?

This happens probably the sequence of events triggered on left mouse double click are WM_LBUTTONDOWN, WM_LBUTTONUP, WM_LBUTTONDBLCLK, and WM_LBUTTONUP. i.e it triggers the WM_LBUTTONDOWN, so how do I handle this?

你不能压制这种行为。您可以做的是在第一次单击时启动一次性计时器，其中间隔设置为报告的毫秒数GetDoubleClickTime()。如果发生双击，请停止计时器并执行双击逻辑。如果计时器到时，请停止计时器并改为执行单击逻辑。
