GetMessagePos function

Retrieves the cursor position for the last message retrieved by the GetMessage function.

To determine the current position of the cursor, use the GetCursorPos function.

Syntax

DWORD GetMessagePos(

);

Parameters

This function has no parameters.

Return Value

Type: Type: DWORD

The return value specifies the x- and y-coordinates of the cursor position. The x-coordinate is the low order short and the y-coordinate is the high-order short.

Remarks

As noted above, the x-coordinate is in the low-order short of the return value; the y-coordinate is in the high-order short (both represent signed values because they can take negative values on systems with multiple monitors). If the return value is assigned to a variable, you can use the MAKEPOINTS macro to obtain a POINTS structure from the return value. You can also use the GET_X_LPARAM or GET_Y_LPARAM macro to extract the x- or y-coordinate.

Important  Do not use the LOWORD or HIWORD macros to extract the x- and y- coordinates of the cursor position because these macros return incorrect results on systems with multiple monitors. Systems with multiple monitors can have negative x- and y- coordinates, and LOWORD and HIWORD treat the coordinates as unsigned quantities.
