This article was previously published under Q80934 SUMMARY
The FilterIndex property of the Common Dialog custom control (COMMDLG.DLL)
can be any long integer value, including negative numbers and 0 (zero).
MORE INFORMATION
Normally, the smallest value to which you would set the FilterIndex
property is 1, because the first filter is defined as 1. If you use a
number less than 1, such as 0 or any negative number (within the range
of a long integer), you will get the same result as if you set it
equal to 1.
Likewise, if you use a number greater that the total number of
filters, the FilterIndex property will function as if you set it to
the last of the filters.
For example, if you have three filters and you set FilterIndex to -2,
it will function as if you set FilterIndex to 1. If you set FilterIndex
to 23, it will function as if you set FilterIndex to 3.
