EXCEL-VBA。获取单元格值作为键值对

舞会

我正在尝试从列“ I”的Excel单元格获取地址值，并将其作为查询字符串传递给使用VBA的URL。在Excel中嵌入了“ Microsoft Object Browser”以加载页面。

这有可能吗？因为我担心作为查询字符串传递的数据量太高（大约1000行）。

代码无法正常工作，有什么办法可以通过将查询字符串作为数组传递来做同样的事情吗？

我也需要VBA语法来解析字典值。

我是VBA的新手。请帮忙。

    Dim Arr() As Variant ' declare an unallocated array.
Arr = Range("I:I") ' Arr is now an allocated array
Set dict = CreateObject("Scripting.Dictionary")
Dim iRow As Integer
iRow = 1
 Dim parms As Variant
   Dim rg As Range
    For Each rg In Sheet1.Range("I:I")
        ' Print address of cells that are negative
        'MsgBox (rg.Value)
         'result = result & rg.Value
          dict.Add rg.Value
          iRow = (iRow + 1)        
    Next
MsgBox (dict.Item(1))
Set dict = Nothing
'WebBrowser1.Navigate2 "http://localhost/excelmaps/maps.php?adr=" & parms
End Sub

IE的最大URL长度似乎为2083个字符：

https://support.microsoft.com/zh-CN/kb/208427

要构建查询，我将使用字符串生成器（“ System.Text.StringBuilder”）。您还需要对所有参数进行URL编码。

这是一个使用范围为[A1：B10]的名称/值构建网址的示例：

Sub BuildURL
  ' Read the names/values from a sheet
  Dim names_values()
  names_values = [A1:B10].Value2

  ' Create a string builder
  Dim sb As Object
  Set sb = CreateObject("System.Text.StringBuilder")
  sb.Append_3 "http://localhost/excelmaps/maps.php"

  ' Build the query
  Dim i&, name$, value$
  For i = 1 To UBound(names_values)
    name = names_values(i, 1)
    value = names_values(i, 2)

    If i = 1 Then sb.Append_3 ("?") Else sb.Append_3 ("&")
    sb.Append_3 URLEncode(name) ' Adds the name
    sb.Append_3 "="
    sb.Append_3 URLEncode(value) ' Adds the value
  Next

  ' Print the result
  Debug.Print sb.ToString()
End Sub


Public Function URLEncode(url As String, Optional space_to_plus As Boolean) As String
  Static ToHex(15), IsLiteral%(127), buffer() As Byte, bufferCapacity&
  Dim urlBytes() As Byte, bufferLength&, i&, u&, b&, space&

  If space_to_plus Then space = 32 Else space = -1
  If bufferCapacity = 0 Then GoSub InitializeOnce
  urlBytes = url

  For i = 0 To UBound(urlBytes) Step 2
    If bufferLength >= bufferCapacity Then GoSub IncreaseBuffer

    u = urlBytes(i) + urlBytes(i + 1) * 256&
    If u And -128 Then    ' U+0080 to U+1FFFFF '
      If u And -2048 Then ' U+0800 to U+1FFFFF '
        If (u And 64512) - 55296 Then ' U+0800 to U+FFFF '
          b = 224 + (u \ 4096):       GoSub WriteByte
          b = 128 + (u \ 64 And 63&): GoSub WriteByte

        Else  ' surrogate  U+10000 to U+1FFFFF '
          i = i + 2

        End If

        b = 192 + (u \ 64):    GoSub WriteByte
        b = 128 + (u And 63&): GoSub WriteByte
