Detecting the mouse position in an Excel sheet using VBA can be a bit tricky because VBA doesn’t natively support events related to the mouse, such as its position on the worksheet. However, you can use Windows API functions to get the mouse cursor position.
First, you need to declare the necessary API functions at the top of a module. The GetCursorPos function from the user32.dll library is used to get the mouse position.
Here is an example of how you can do this:
-
Declare the API Functions:
Declare PtrSafe Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long
GetCursorPos is the function that gets the current cursor position.
POINTAPI is a custom type that will hold the X and Y coordinates of the cursor.
-
Function to Get Mouse Position:
You can then write a function that uses GetCursorPos to retrieve the mouse position.
Function GetMousePosition() As POINTAPI
-
Using the Function:
You can call GetMousePosition to get the current mouse coordinates. Note that these coordinates are relative to the entire screen, not just the Excel application or a specific worksheet.
MsgBox "Mouse Position - X: " & pt.X & ", Y: " & pt.Y
Keep in mind that this approach provides the screen coordinates of the mouse cursor, not its position relative to cells in an Excel worksheet. Calculating the mouse’s position over a specific cell would require additional calculations based on the Excel window’s position and size, and the layout of the sheet.
Also, ensure that your VBA project is set up to handle PtrSafe and API calls, which is especially important in 64-bit versions of Office.
