# 2.1.27.7 GetDialogBaseUnits

## Description

This function returns the system's dialog base units, which are the average width and height of characters in the system font.

## Syntax

long GetDialogBaseUnits( void )

void

## Return

The function returns the dialog base units. The low-order word of the return value contains the horizontal dialog box base unit, and the high-order word contains the vertical dialog box base unit.

## Remark

The horizontal base unit returned by GetDialogBaseUnits is equal to the average width, in pixels, of the characters in the system font; the vertical base unit is equal to the height, in pixels, of the font.

The system font is used only if the dialog box template fails to specify a font. Most dialog box templates specify a font; as a result, this function is not useful for most dialog boxes.
