Creating an Excel VBA function that adjusts the row height to fit exactly 64 rows on the visible canvas, regardless of screen resolution, OS, window size, etc., involves a few challenges. The main issue is that Excel’s row height and column width settings do not directly correlate to pixels in a straightforward way, as they depend on the display settings, Excel’s internal scaling, and the font size used in the cells. Additionally, Excel’s VBA does not provide direct access to the Excel window size in pixels or the screen resolution.

However, I can guide you through creating a VBA function that attempts to adjust the row height dynamically to aim for displaying approximately 64 rows within the visible part of an Excel worksheet. This approach involves estimating the visible area and adjusting the row heights accordingly. Please note, due to the factors mentioned above, achieving pixel-perfect accuracy for all possible setups might not be feasible.

Here’s a conceptual approach:

1. Estimate Visible Rows: Use Excel VBA to estimate the number of visible rows in the current window.
2. Calculate Desired Row Height: Based on the estimated visible area, calculate the desired row height to make 64 rows fit in the visible area.
3. Apply Row Height Adjustment: Adjust the row height of the rows to match the calculated height.

VBA Code Example

Sub AdjustRowHeightToFit64()
    Dim totalVisibleHeight As Double
    Dim desiredRowHeight As Double
    Dim visibleRows As Integer
    Dim i As Integer

    ' Estimate the total visible height available for rows (in points)
    ' Note: This is a rough estimation. You might need to adjust the calculation based on your needs.
    With ActiveWindow
        totalVisibleHeight = .UsableHeight
    End With

    ' Calculate the desired row height to fit exactly 64 rows
    ' Subtracting a small value to account for the horizontal scrollbar height, if visible
    desiredRowHeight = (totalVisibleHeight - 5) / 64

    ' Apply the calculated row height to the first 64 rows as an example
    For i = 1 To 64
        Rows(i & ":" & i).RowHeight = desiredRowHeight
    Next i
End Sub

Instructions:

1. Open Excel and press Alt + F11 to open the VBA Editor.
2. Insert a new module: Right-click any of the objects in the Project window, choose Insert > Module.
3. Paste the VBA code into the module window.
4. Run the AdjustRowHeightToFit64 subroutine.

Important Considerations:

• Estimation and Scaling: The above code provides a starting point and may need adjustments, especially in the estimation of the visible area (totalVisibleHeight calculation). The subtraction of 5 points is an arbitrary value to account for potential scrollbars and may not be accurate for all setups.
• Excel’s Limitations: Excel and VBA have limitations in precisely controlling and measuring UI elements due to varying user interfaces across different Excel versions, screen resolutions, and display settings.

This solution offers a general approach but may require further customization to work seamlessly across all possible user environments. Experimenting and adjusting the calculations based on specific requirements and testing on target setups will be necessary for optimal results.
