Module: Search in Category General VBA/VB6 : Searching and Sorting from Total Visual SourceBook

Binary and Linear Search routines and Soundex function in VBA and VB6.

Procedure List

Procedure Name	Type	Description
(Declarations)	Declarations	Declarations and private variables for the modSearch module.
BinarySearchVariant	Procedure	Use a binary search to find a value in an array. The array must be zero based and sorted for this procedure to function correctly. Note: This function works on arrays of variants, but not a variant array.
LinearSearchVariant	Procedure	Use a linear search to find a value in an array. The array must be zero based and sorted for this procedure to function correctly. Note: This function works on arrays of variants, but not a variant array.
LinearSearchVariantUnsorted	Procedure	Use a linear search to find a value in an array. This function is not optimized for sorted data. See LinearSearchVariant for a function that is optimized for Sorted Data. The array must be zero based and sorted for this procedure to function correctly. Note: This function works on arrays of variants, but not a variant array.
Soundex	Procedure	Create a Soundex key for a string which is helpful for finding close but not exact data, such as de-duping addresses and spelling differences/typos between names. Soundex is based on the principle that English words can be distinguished by their consonants. The Soundex algorithm generates a string based on the first character of the string, followed by the consonants contained in the string.

Example Code for Using Module: Search

' Example of modSearch
'
' To try this example, do the following:
' 1. Create a new form
' 2. Create a command button named 'cmdTest'
' 3. Paste all the code from this example to the new form's module.
' 4. Run the form

Private Sub cmdTest_Click()
  Dim avarIn() As Variant
  Dim lngIndex As Long
  Dim i As Integer
  Dim dblFindItem As Double

  Randomize Timer

  ' Create array
  ReDim avarIn(1000)
  For i = 0 To 1000
    avarIn(i) = i
  Next i

  ' Example of LinearSearchVariantUnsorted
  dblFindItem = Int((1000 - 1 + 1) * Rnd + 1)
  lngIndex = LinearSearchVariantUnsorted(avarIn, dblFindItem)
  Debug.Print " LinearSearchVariantUnsorted Item " & dblFindItem & " is at " & lngIndex

  ' Example of LinearSearchVariant
  dblFindItem = Int((1000 - 1 + 1) * Rnd + 1)
  lngIndex = LinearSearchVariant(avarIn, dblFindItem)
  Debug.Print "LinearSearchVariant Item " & dblFindItem & " is at " & lngIndex

  ' Example of BinarySearchVariant
  dblFindItem = Int((1000 - 1 + 1) * Rnd + 1)
  lngIndex = BinarySearchVariant(avarIn, dblFindItem)
  Debug.Print "BinarySearchVariant Item " & dblFindItem & " is at " & lngIndex

  ' Example of Soundex (defaults to 4 characters)
  Debug.Print Soundex("Microsoft Corporation")
  ' Generate a 7 character soundex
  Debug.Print Soundex("Microsoft Corporation", 7)

End Sub
