Installation Instructions for Office add-ins

I updated the installation instructions for Office VBA add-ins to include Office 2010, Office 2007, and Office 2003. The updated material is at http://www.tushar-mehta.com/excel/software/installation/index.htm.

Minimum and maximum values of numeric data types

There has been many an occasion when I have wanted programmatic access to the maximum or minimum or smallest value of a data type. Some programming languages have built-in support through names like MaxInt. VBA, unfortunately, is not one of them.

I decided to “translate” the documentation defining the different data types into code. The functions Max{datatype}, Min{datatype}, and Smallest{datatype} return the appropriate value. The Max and Min functions should be self-evident. The Smallest function returns the smallest non-zero value supported by the data type. Since this is simply 1 for all data types associated with integers (Byte, Integer, Long, LongPtr, LongLong, and Currency), Smallest is defined only for data types associated with real numbers (Single, Double, and Decimal).

Highlight row and column of active cell

By default, when the user selects a cell, Excel highlights the row and column by changing the color of the associated row and column headers. This tip shares multiple ways to highlight the row and column in more obvious ways as well as a way to highlight the cell in a specific column in the same row.


The emphasis is on the use of conditional formatting to accomplish the task. The minimal VBA code required to make it work is the same single executable statement for all of the different highlighting options!
