[vba] Excel VBA If cell.Value =... then

I have this code which works well:

Sub colortest()
Dim cell As Range
For Each cell In Range("Range1")
If cell.Value = "Word1" Then
cell.Interior.Color = XlRgbColor.rgbLightGreen
ElseIf cell.Value = "Word2" Then
cell.Interior.Color = XlRgbColor.rgbOrange
ElseIf cell.Value = "Word3" Then
cell.Interior.Color = XlRgbColor.rgbRed
End If
Next cell
End Sub

My problem is the values work only if the cell contains only that text. But my cells are usually like this: "Something, 10254, 15/15, Word1 Another Word" I only need the Word1. Thank you,

I think it would make more sense to use "Find" function in Excel instead of For Each loop. It works much much faster and it's designed for such actions. Try this:

 Sub FindSomeCells(strSearchQuery As String)   

    Set SearchRange = Worksheets("Sheet1").Range("A1:A100")
    FindWhat = strSearchQuery
    Set FoundCells = FindAll(SearchRange:=SearchRange, _
                            FindWhat:=FindWhat, _
                            LookIn:=xlValues, _
                            LookAt:=xlWhole, _
                            SearchOrder:=xlByColumns, _
                            MatchCase:=False, _
                            BeginsWith:=vbNullString, _
                            EndsWith:=vbNullString, _
                            BeginEndCompare:=vbTextCompare)
    If FoundCells Is Nothing Then
        Debug.Print "Value Not Found"
    Else
        For Each FoundCell In FoundCells
            FoundCell.Interior.Color = XlRgbColor.rgbLightGreen
        Next FoundCell
    End If

End Sub

That subroutine searches for some string and returns a collections of cells fullfilling your search criteria. Then you can do whatever you want with the cells in that collection. Forgot to add the FindAll function definition:

Function FindAll(SearchRange As Range, _
                FindWhat As Variant, _
               Optional LookIn As XlFindLookIn = xlValues, _
                Optional LookAt As XlLookAt = xlWhole, _
                Optional SearchOrder As XlSearchOrder = xlByRows, _
                Optional MatchCase As Boolean = False, _
                Optional BeginsWith As String = vbNullString, _
                Optional EndsWith As String = vbNullString, _
                Optional BeginEndCompare As VbCompareMethod = vbTextCompare) As Range
'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' FindAll
' This searches the range specified by SearchRange and returns a Range object
' that contains all the cells in which FindWhat was found. The search parameters to
' this function have the same meaning and effect as they do with the
' Range.Find method. If the value was not found, the function return Nothing. If
' BeginsWith is not an empty string, only those cells that begin with BeginWith
' are included in the result. If EndsWith is not an empty string, only those cells
' that end with EndsWith are included in the result. Note that if a cell contains
' a single word that matches either BeginsWith or EndsWith, it is included in the
' result.  If BeginsWith or EndsWith is not an empty string, the LookAt parameter
' is automatically changed to xlPart. The tests for BeginsWith and EndsWith may be
' case-sensitive by setting BeginEndCompare to vbBinaryCompare. For case-insensitive
' comparisons, set BeginEndCompare to vbTextCompare. If this parameter is omitted,
' it defaults to vbTextCompare. The comparisons for BeginsWith and EndsWith are
' in an OR relationship. That is, if both BeginsWith and EndsWith are provided,
' a match if found if the text begins with BeginsWith OR the text ends with EndsWith.

You can use the Like operator with a wildcard to determine whether a given substring exists in a string, for example:

If cell.Value Like "*Word1*" Then
'...
ElseIf cell.Value Like "*Word2*" Then
'...
End If

In this example the * character in "*Word1*" is a wildcard character which matches zero or more characters.

NOTE: The Like operator is case-sensitive, so "Word1" Like "word1" is false, more information can be found on this MSDN page.
