The source code in this issue is designed for Visual Basic 5.0 and above. If you want to make this source code work under VB 4.0 32-bit, just change the Enum types to normal Const values. You will also have to remove the optional parameter or change its data type to Variant.
If you have any questions about this issue, please email us at email@example.com
This issue shows one way to format a large number into a more readable number. Windows 95 uses this type of formatting when showing the total disk space and free disk space in Windows Explorer. It will automatically change the number from bytes to kilobytes to megabytes to gigabytes depending on the number. We probably should have added terabytes but thought that only a few of you might even have access to a terabyte storage device.
There is one public function that performs all the number formatting. You need to pass it a number with the data type Double. If you want a particular number format returned, you can pass an eNumberFormat enumerator as a parameter. If you do not pass it, it will default to nf_BestFit.
Public Function SmartNumberFormat(dblNumber As Double, _ Optional eReturnType As eNumberFormat = nf_BestFit) As String
Debug.Print SmartNumberFormat(212) ' will show 212 in debug window Debug.Print SmartNumberFormat(420212) ' will show 410.4KB in debug window Debug.Print SmartNumberFormat(420233927) ' will show 400.8MB in debug window Debug.Print SmartNumberFormat(42021233927) ' will show 39.1GB in debug window Debug.Print SmartNumberFormat(21123262,fsd_KiloBytes) ' will show 20,628.2KB in debug window
