<div>
Both WM_LBUTTONUP and WM_MOUSEMOVE messages contain cursor coordinate in lParam parameter:<br />
<br />
The low-order word specifies the x-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area. <br />
The high-order word specifies the y-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area. <br />

Dear Guys.<br />
<br />
I want to capture the MouseMove and WM_LBUTTONUP Messages in WindowsCE platform, inside these messages I used the GetCursorPos function to get the mouse cursor function, the main problem that this function always returns 0, which means that the function is failed, when I used the GetLast Error, I find that the error code is 120, when I look for the this code in MSDN, MSDN tells me that this error means &quot;This function is not valid on this platform. &quot;, Now I need to get the position of the mouse cursor using another function, So how I can I do that in Windows CE ?<br />
<br />
<br />
Thank you in advance.

GetCursorPos Function

Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages. It features tools for developing and debugging C++ code, especially code written for the Microsoft Windows API, the DirectX API, and the Microsoft .NET Framework. Many applications require redistributable Visual C++ packages to function correctly and are often installed independently of applications, allowing multiple applications to make use of the package while only having to install it once
