FastExcel Sample problems and Output: FXLSampleProblemV2.zip .

Revised 12 Sep 2004. These workbooks do NOT require FastExcel.

The FastExcel samples download is approximately 1.5MB (approximately 8 minutes at 28K). The package is a ZIP file containing four Excel workbooks and a PDF manual:

  • FXLSamplProblemV2.pdf: The FastExcel Version 2 Sample problem Guide.
  • FXLSampV2.xls: contains the output from a FastExcel analysis of these workbooks, and an explanation of the analysis and the optimisations done on the After.xls and NoNamesAfter.xls workbook.
  • Before.xls: the unoptimised workbook, calculates in 22 seconds on a 1200 MHZ AMD Athlon
  • After.xls: the optimised workbook with dynamic range names, calculates in 0.17 seconds at 1200 MHZ
  • NoNamesAfter.xls: the optimised workbook with the range names removed, calculates in 0.03 seconds at 1200 MHZ

Counting Functions: fxlCountFuncs.zip :run-time functions for the FastExcel Dynamic Range Wizard

This addin contains a set of functions designed to be used in Dynamic Range Names. The addin can be used as a runtime library for workbooks whose dynamic range names have been geberated by the FastExcel Dynamic Range Wizard. The addin works with Excel 97, Excel2000, Excel 2002 and Excel 2003.

Although it is possible to duplicate some of these functions using array formulae, these functions calculate significantly faster than the equivalent array formulae.

The password for the XLA file is dm.

The Functions in the addin are registered into category 5 of the excel Function wizard (Lookup and Reference).

These functions give you the ability to find the number of rows or columns to the last empty cell, the next empty cell, or the last cell in the used range:

  • COUNTROWS and COUNTCOLS count the number of rows or columns from a referenced cell to the last visible non-empty cell in the row or column.
  • COUNTCONTIGROWS and COUNTCONTIGCOLS count the number of rows or columns from a referenced cell to before the next visible empty cell.
  • COUNTUSEDROWS and COUNTUSEDCOLS count the number of rows or columns from a referenced cell to the last cell in the used range.

You can use these functions in Dynamic Range names and for the number of rows and columns arguments in OFFSET.

COUNTROWS and COUNTCONTIGROWS can count rows in either a single column or multiple adjacent columns.
Similarly COUNTCOLS and COUNTCONTIGCOLS can count columns in either a single row or multiple adjacent rows.

All these functions are volatile functions.

Changing cell visibility using Automatic or Advanced filter will trigger a recalculation of COUNTROWS, COUNTCOLS, COUNTCONTIGROWS and COUNTCONTIGCOLS.
Changing cell visibility using Hide, Unhide or by setting width or height to zero will NOT trigger a recalculation of COUNTROWS, COUNTCOLS, COUNTCONTIGROWS and COUNTCONTIGCOLS.

Full descriptions of these functions are givrn in the downloadable FastExcel Manual (PDF).

RangeCalc Add-In: RangeCalc.zip: one of the FastExcel command buttons

This addin adds a Calculate Range button to Excel. This button calculates the currently selected cells, and times the calculation using the MicroTimer high-resolution timer. RangeCalc automatically expands the current selection to include all the cells of any multi-cell array formulae that partly intersect the selected range.

The addin works with Excel 97 through Excel 2010 (both 32 and 64 bit versions), and bypasses many of the quirks of Range.Calculate such as the Iteration and Array Formulae problems in Excel2002/3/7.

The password for this addin is dm.

Add-In Loader Version 2: AddloaderV2.ZIP

Revised 18 November 2014:

  • Handle both XLA and XLAM files

Revised 11 April 2006:

  • Runs Auto-Open and Auto-Close macros in addins when they are opened or closed.
  • Bug fix for opening addins with auto option followed by addins without auto option.

The Add-In Loader is designed to solve some of the problems of maintaining and loading Add-Ins on a network:

    Dynamic reversioning of add-ins with automatic link updating.

    Control from a central point which add-ins will be automatically loaded when Excel starts.

    Control from a central point which add-ins will be available for on-demand loading.

    Enable updated versions of an add-in to be placed on a server at the same time as previous versions are in use.

    Optionally specify and/or change the network path for each add-in.

    No Registry changes for load and unload.

The Add-In Loader helps the User:

    Improve Excel start-up time by bypassing the loading of add-ins that are only needed intermittently.

    Minimize memory use by loading add-ins when needed and easily unloading them when not needed.

    Dynamically load the latest version of an add-in, whilst unloading any version which is currently loaded.

    Dynamically update any links that point to old versions of loaded add-ins when a workbook is opened or an add-in is loaded.

The Zip file contains:

    AddLoaderV2.XLA - the Add-InLoader Add-In.

    AddinLoad.txt - example file containing test Add-In Root names.

    Add-in Loader V2.Doc - Word document explaining how to install and use the Add-In Loader V2.

You can customise the Add-In Loader code as required. The XLA is password protected to prevent accidental alteration.

To view the VBA code in the Addin unprotect the XLA using a password of dm

Version 2 Changes:

    Option to specify the network path for add-ins.

    Option to automatically load add-ins.

    Improved View/Unload command.

    Dynamic link updates when a workbook is opened or an add-in is loaded.

Version 1 Revisions:

25/May/2001: fix for chDrive and UNC Path

Calculation Tracer: CalcTrace.ZIP

This Add-In file contains User Functions and a macro designed to enable you to explore Excel's calculation sequence and dependency handling.
Note that interpreting the results and designing conclusive experiments can be complex.

The functions work by incrementing and returning a counter each time they are calculated:

    ZeroCalcSeq  - a Macro which sets the counter to zero.

    CalcSeqCountSet(theInput)  - Function - Counter is set to theInput.

    CalcSeqCountRef(theRange)  - Function - Counter is incremented as a dependency on theRange.

    CalcSeqCountVol()  - The function is volatile: - Counter is incremented at each Calculation: used to check the effect of volatile on calculation sequence.

The functions may be entered from the User section of the Function Wizard, or entered directly into a worksheet formula.

The XLA password is dm

Memory Limit example of interlinked sheets: MakeInterlinkedSheets.zip (11KB)

Updated 9 Jan 2004 to allow generating more than 255 sheets and for comments on excel 2003.

This zip file contains a workbook with a VBA macro that generates a variable number of interlinked worksheets. It demonstrates an extreme case of the memory used by interlinked sheets, some of Excel's memory limits, and that it is possible to create a workbook that you cannot re-open!

Use thuis example file to test Excels's memory limits by version.

UDF Areas Bug Example and Bypass: AreasBugBypass2.zip

Howard Kaikow http://www.standards.com, discovered a bug that can occur in Excel's processing of multi-area input arguments for a UDF, and can result in the UDF calculating incorrectly. The bug exists in Excel 97, Excel 2000, Excel 2002 and partially in Excel 2003. It has been fixed in Excel 2007. Some of Excel's own functions also have this problem (but not SUM).

The bug occurs when a UDF has a multi-area input argument that refers to the sheet containing the function formula, and the function is recalculated by Excel when a different sheet is the activeSheet. In this case the function will incorrectly use data from the activesheet.

It is possible to bypass the bug at the expense of making the UDF Volatile, modifying it and adding a dummy worksheet containing a worksheet calculate event.

The downloadable zip file contains two workbooks:

    AreasBug2.xls demonstrates the bug.

    AreasBugBypass2.xls demonstrates a method of bypassing the bug.

If you write a UDF which processes multi-area arguments you should implement a similar bypass.

With Excel 2003 the bug has been fixed for multi-area references that explicitly reference other sheets ((Sheet2!$A$1:$A$3),(Sheet3!$B$1:$B$3)) but not for implicit references (($A$1:$A$3),($B$1:$B$3)).

High Resolution Timers: Timers.ZIP

This Add-In contains VBA function wrappers for Windows API high resolution timers. These functions are useful when you need greater accuracy than is available from the VBA Timer (which turns out to be most of the time). VBA Timer is also quite slow to execute.
Portions of the code in these functions are from Ken Getz and John Green.

Mostly I use the code in these functions as timers within VBA, but you can also use them as UDF's.
To use as a timer, call the function, execute the thing you want to time, call the function again and subtratct the second time from the first.

The XLA password is dm

The functions measure elapsed time rather than processor time.
The two functions are:

    Microtimer: returns a Double containing seconds. Resolution about 1 microsecond and takes about 5 microseconds to execute in Win ME at 1200MHZ

    Millitimer:   returns a Long containing milliseconds. Resolution about 1 millisecond and takes about 5 microseconds to execute in Win ME at 1200MHZ
