Excel VBA - 删除最多* word *的字符串内容

Question

I'm trying to delete string content up to a certain word contained within the string. For example

"Emily has wild flowers. They are red and blue."

I'd like to use VBA in order to replace that with

"They are red and blue."

ie remove all the content up to the word "They". I don't know the string content and the number of characters contained in it.

I'm not sure how to do this and I'd really appreciate your help!

Answer 1

Here you go:

Dim s As String
s = "Emily has wild flowers. They are red and blue."

Dim indexOfThey As Integer

indexOfThey = InStr(1, s, "They")


Dim finalString As String
finalString = Right(s, Len(s) - indexOfThey + 1)

Answer 2

Simple example of dropping all text before value in string.

Sub Foo()
    Dim strOrig As String
    Dim strReplace As String
    strOrig = "The Quick brown fox jumped over the lazy dogs"
    strReplace = "jumped"

    MsgBox (DropTextBefore(strOrig, strReplace))

End Sub

Public Function DropTextBefore(strOrigin As String, strFind As String)
    Dim strOut As String
    Dim intFindPosition As Integer
    'case insensitive search
    'could made it so that case sensitivity is a parameter but this gets the idea across.
    If strOrigin <> "" And strFind <> "" Then
        intFindPosition = InStr(UCase(strOrigin), UCase(strFind))
        strOut = Right(strOrigin, Len(strOrigin) - (intFindPosition + Len(strFind) - 1))
    Else
      strOut = "Error Empty Parameter in function call was encountered."
    End If
    DropTextBefore = strOut
End Function

This worked great for me:

Sub remove_until()

Dim i, lrowA, remChar As Long
Dim mString As String

lrowA = ActiveSheet.Cells(Rows.Count, 1).End(xlUp).Row

For i = 1 To lrowA

mString = Cells(i, 1).Value


    If InStr(mString, "They") > 0 Then

    remChar = Len(mString) - InStr(mString, "They") + 1

    Cells(i, 2).Value = Left(mString, Len(mString) - remChar)

    End If


Next

End Sub

Answer 4

If the word is fixed, like "They" in the above example, you can simply do

1. CTRL + H (Replace)
2. *They (your word with a star)

in the Find box. The star * is a wildcard character which can be called as - of anything before or after (if added at end) the word.

Cautious: Take care when you have duplicate words in the same cell.
