我正在尝试弹出一个框,列出一些可能为空的值。
MsgBox (res1 & vbNewLine & _
res2 & vbNewLine & _
res3 & vbNewLine & _
res4 & vbNewLine & _
res5 & vbNewLine & _
res6 & vbNewLine & _
res7 & vbNewLine & _
res8 & vbNewLine & _
res9 & vbNewLine & _
res10 & vbNewLine & _
res11 & vbNewLine & _
res12 & vbNewLine)
我想要做的就是这样:
if res1 <> "" then
res1 & vbNewLine
else
""
end if
因为此时显示的是空白行的加载:

好悲伤每个人都在努力做到这一点......
将所有字符串变量存储在一个数组中,然后创建一个接收数组的BuildMessage
函数,然后遍历它,返回最后的消息。
Public Sub Test()
Const res1 As String = vbNullString
Const res2 As String = "Hello"
Const res3 As String = vbNullString
Const res4 As String = "GoodBye"
Const res5 As String = vbNullString
Dim resArr As Variant
resArr = Array(res1, res2, res3, res4, res5)
Dim msg As String
msg = BuildMessage(resArr)
MsgBox msg
End Sub
Private Function BuildMessage(ByVal arr As Variant) As String
Dim msg As String
Dim i As Long
For i = LBound(arr) To UBound(arr)
Dim str As String
str = arr(i)
If str <> vbNullString Then
msg = msg & str & vbNewLine
End If
Next
BuildMessage = msg
End Function

如果您不想在msgbox函数调用之外创建字符串,则可以使用内联:
MsgBox (res1 & Iif(res1<>"", vbNewLine, "") & _
res2 & Iif(res2<>"", vbNewLine, "") & _
res3 & Iif(res3<>"", vbNewLine, "") & _
res4 & Iif(res4<>"", vbNewLine, "") & _
res5 & Iif(res5<>"", vbNewLine, "") & _
res6 & Iif(res6<>"", vbNewLine, "") & _
res7 & Iif(res7<>"", vbNewLine, "") & _
res8 & Iif(res8<>"", vbNewLine, "") & _
res9 & Iif(res9<>"", vbNewLine, "") & _
res10 & Iif(res10<>"", vbNewLine, "") & _
res11 & Iif(res11<>"", vbNewLine, "") & _
res12 & Iif(res12<>"", vbNewLine, "") )

您可以声明一个String,并构造字符串以显示字符。像,
Dim tmpRes As String
If Len(res1) > 0 Then _
tmpRes = tmpRes & res1 & vbCrLf
If Len(res2) > 0 Then _
tmpRes = tmpRes & res2 & vbCrLf
If Len(res3) > 0 Then _
tmpRes = tmpRes & res3 & vbCrLf
If Len(res4) > 0 Then _
tmpRes = tmpRes & res4 & vbCrLf
If Len(res5) > 0 Then _
tmpRes = tmpRes & res5 & vbCrLf
If Len(res6) > 0 Then _
tmpRes = tmpRes & res6 & vbCrLf
If Len(res7) > 0 Then _
tmpRes = tmpRes & res7 & vbCrLf
If Len(res8) > 0 Then _
tmpRes = tmpRes & res8 & vbCrLf
If Len(res9) > 0 Then _
tmpRes = tmpRes & res9 & vbCrLf
If Len(res10) > 0 Then _
tmpRes = tmpRes & res10 & vbCrLf
MsgBox tmpRes
