Note A range will always return a multi-dimensional array, usually two dimensions, regardless of the number of columns. The second dimension will contain at least one ele ment but could have more depending upon the number of columns within the range. If you need to determine the size of an array, you can use the LBound and UBound functions to give you the lower and upper boundaries of the array. LBound(var) returns the lower boundary, usually a 0 or 1, whereas UBound(var) will return the upper boundary. 185

Microsoft Office Excel 2003 Programming Inside Out To determine the boundaries of all dimensions in a multi-dimensional array, specify the dimension you want the boundary of. For example, using the statement varA = Range("JanuaryAllValues") in the Y2001ByMonth.xls workbook would read all the cells from B3:Q38. To find the number of rows, you could use UBound(varA, 1) or simply UBound(varA). Retrieving the number of columns would use the command UBound(varA, 2). When reading the values from a named range, you can also shrink or expand the number of cells being read by using the Resize method. As an example, to read only the first seven rows of data, but three hours worth of data from 1:00 P.M. in the Y2001ByQuarter.xls workbook, you could use the following statement:

Writing information back into the range is a simple reversal of the statement, Range("January1PM") = varA. However, some care should be taken when writing information back into the cells. You should ensure that the range is the same size as the array to prevent overwriting the wrong cells. This is to preserve data integrity and is easily done by combining the UBound function with the Resize method, as follows:
Range("January1PM").Resize(UBound(varA, 1), UBound(varA, 2)) = varA.
A simpler method of ensuring the integrity of your data is to fill the array with the values from the range first. This method will actually serve two purposes: it will size the array to match the range, and it will fill the array with the current values contained within the range so that when the data is written back Excel will maintain the values that have not been changed within the procedure. The following procedure helps illustrate the difference in processing times between using direct access to the cells and copying the cells to an array first. (Each method is repeated 50 times so that the time needed to perform the reads is high enough to measure.)

Getting Data Entry Right the First Time
Typing data into a worksheet or form is one of the most tedious activities known to humanity. If you ve ever typed ISBNs into a database eight hours a day and five days a week for two months, you can begin to ge an appreciation for what data entry clerks go thr ugh. Columns t o of numbers transpose in front of your eyes, books you ve already entered find their way onto your to do pile, and you change hands to avoid the worst effects of repetitive stress disorders. Add in the potential for typographical errors, and you can understand why electronic data collections are so notoriously inaccurate. You can help catch data entry errors at the source by setting validation rules for cells in your worksheets. As the name implies, a validation rule is a criterion that cell data must meet in order to ensur that only m e eaningful information is added to y ur data collection. You get to o choose whether the invalid data is accepted as input or whether the user has to re-type the data b efore b eing alowed to g o to he n cel. Y c n aso pecify w l o n t ext l ou a l s hether to alow u l sers entering data to leave cells blank. The key to creating validation rules for your cells is, as you probably guessed, the Range object s Validation property. The Validation property, which returns a Validation object, gives you the tools to set the validation rules and notification styles for your cell ranges. Table 8-4 lists the Validation object s useful properties and methods.
