[英]Changing the value of a a cell if another cell is equal to a certain value using VBA
[英]VBA - Copy value if cell CONTAINS certain value rather than equal to or not equal to
我有一個工作宏,循環文件夾打開文件,從名稱“HOLDER”和“CUTTING TOOL”的列中獲取重要信息,並將所有信息打印到一個excel文檔,masterfile。
我遇到的問題是,在“HOLDER”欄中,有時會有“Holder / Toolbox”這樣的額外信息,但它並不一致。 我讓它與“HOLDER”一起工作,但我想知道是否仍然可以這樣做,無論HOLDER標題名稱中是否有額外的文本,或者它是小寫而不是所有大寫。 感謝您提供任何幫助!
這是處理“HOLDER”部分的代碼。 下面是完整的代碼以便更好地參考(第4節關於我正在修改的部分,第8部分是它引用的功能)。
'find the headers on the sheet
Set hc1 = HeaderCell(StartSht.Range("B1"), "HOLDER")
...
'(4)
'find HOLDER on the source sheet
Set hc3 = HeaderCell(ws.Cells(ROW_HEADER, 1), "HOLDER")
If Not hc3 Is Nothing Then
Set dict = GetValues(hc3.Offset(1, 0))
If dict.count > 0 Then
Set d = StartSht.Cells(Rows.count, hc1.Column).End(xlUp).Offset(1, 0)
'add the values to the master list, column 2
d.Resize(dict.count, 1).Value = Application.Transpose(dict.items)
End If
Else
'header not found on source worksheet
End If
...
'(8)
'get all unique column values starting at cell c
Function GetValues(ch As Range, Optional vSplit As Variant) As Object
Dim dict As Object
Dim rng As Range, c As Range
Dim v
Dim spl As Variant
Set dict = CreateObject("scripting.dictionary")
For Each c In ch.Parent.Range(ch, ch.Parent.Cells(Rows.count, ch.Column).End(xlUp)).Cells
v = Trim(c.Value)
If Len(v) > 0 And Not dict.exists(v) Then
If Not IsMissing(vSplit) Then
spl = Split(v, ";")
v = spl(0)
End If
If Not IsMissing(vSplit) Then
spl = Split(v, ",")
v = spl(0)
End If
dict.Add c.Address, v
End If
Next c
Set GetValues = dict
End Function

好吧, InStr
有助於找出字符串中是否包含子字符串。 基本上,它返回的是字符串中子字符串的位置; 所以,一行如下:
Instr ("hello world!", "h")
將返回1第一個參數是您要查看的字符串,第二個參數是您要查找的子字符串。
因此,如果返回值不為零,則表示包含子字符串。 你會這樣檢查:
If InStr(string, substring) <> 0 then
'do code
End If
此外,對於區分大小寫的方案:
您可能希望將單元格值放入字符串變量中,但轉換為大寫字母; 然后檢查“HOLDER”等等。 這不會改變單元格中的值,只是為了比較。 做就是了:
dim uString as String
uString = UCase(c.Value)
需要調整的部分是搜索標題行,比較值的部分。 看起來這是在HeaderCell函數中。 看起來比較的具體線是:
If Trim(c.Value) = sHeader Then
這是將標題行中每個單元格的內容與傳入的值(在您的情況下為sHeader =“Holder”)進行比較。
你最好做一個測試,看看sHeader是否在單元格值中,不等於單元格值。 InStr功能非常適合這種情況。 (未經測試的航空代碼):
If InStr(c.Value, sHeader) <> 0 Then
這將搜索標題行中每個單元格的內容,以查看傳遞給sHeader的值是否在值的任何位置。
