我的工作表有三列「A」=圖像，「B」=圖像名稱和「C」= URL鏈接，第1行和第2行用作頁眉和行3至1002用於用戶輸入。當前工作代碼將在您選擇的文件夾的列「B」中搜索圖像名稱，並將其插入列「A」。這個宏運行在我已經創建的用戶窗體上的命令按鈕上。通過URL鏈接將圖像放到Excel表格中
工作的代碼如下（這是公認的答案here的編輯版本）：
Private Sub Add_Images_Click()
Const EXIT_TEXT As String = ""
Const NO_PICTURE_FOUND As String = "No picture found"
Dim picName As String
Dim picFullName As String
Dim rowIndex As Long
Dim lastRow As Long
Dim selectedFolder As String
Dim data() As Variant
Dim wks As Worksheet
Dim Cell As Range
Dim pic As Picture
On Error GoTo ErrorHandler
selectedFolder = GetFolder
If Len(selectedFolder) = 0 Then GoTo ExitRoutine
Application.ScreenUpdating = False
Set wks = ActiveSheet
lastRow = wks.Cells(2, "B").End(xlDown).Row
data = wks.Range(wks.Cells(3, "B"), wks.Cells(lastRow, "B")).Value2
For rowIndex = 3 To UBound(data, 1)
If StrComp(data(rowIndex, 1), EXIT_TEXT, vbTextCompare) = 0 Then GoTo ExitRoutine
picName = data(rowIndex, 1)
picFullName = selectedFolder & picName
If Len(Dir(picFullName)) > 0 Then
Set Cell = wks.Cells(rowIndex, "A")
Set pic = wks.Pictures.Insert(picFullName)
With pic
.ShapeRange.LockAspectRatio = msoFalse
.Height = Cell.Height
.Width = Cell.Width
.Top = Cell.Top
.Left = Cell.Left
.Placement = xlMoveAndSize
End With
Else
wks.Cells(rowIndex, "A").Value = NO_PICTURE_FOUND
End If
Next rowIndex
ExitRoutine:
Set wks = Nothing
Set pic = Nothing
Application.ScreenUpdating = True
UserForm.Hide
Exit Sub
ErrorHandler:
MsgBox Prompt:="Unable to find photo", _
Title:="An error occured", _
Buttons:=vbExclamation
Resume ExitRoutine
End Sub
Private Function GetFolder() As String
Dim selectedFolder As String
With Application.FileDialog(msoFileDialogFolderPicker)
.InitialFileName = Application.DefaultFilePath & "\"
.Title = "Select the folder containing the Image/PDF files."
.Show
If .SelectedItems.count > 0 Then
selectedFolder = .SelectedItems(1)
If Right$(selectedFolder, 1) <> Application.PathSeparator Then _
selectedFolder = selectedFolder & Application.PathSeparator
End If
End With
GetFolder = selectedFolder
End Function
我正在尋找一種方式來編輯這個宏，以便它能夠使用的URL鏈接爲「C」列中的圖像，並以這種方式查找圖像並將其插入列「A」。我發現一個工作代碼（不記得在哪裏，或者我會鏈接它），我嘗試使用當前的代碼來實現期望的結果。
示例代碼我在網上找到：
Sub Images_Via_URL()
Dim url_column As Range
Dim image_column As Range
Set url_column = Worksheets(1).UsedRange.Columns("A")
Set image_column = Worksheets(1).UsedRange.Columns("B")
Dim i As Long
For i = 2 To url_column.Cells.Count
With image_column.Worksheet.Pictures.Insert(url_column.Cells(i).Value)
.Left = image_column.Cells(i).Left
.Top = image_column.Cells(i).Top
.Height = 100
.Width = 100
End With
Next
End Sub
下面的代碼是我失敗的嘗試來編輯它自己。它曾經爲7個URL鏈接列表工作過一次，然後我刪除了中間的一個鏈接，看看它是否能正確處理空白單元格，現在它平淡無味。它每次都進入「ExitRoutine」。
不工作代碼：
Option Explicit
Private Sub URL_Images_Click()
Const EXIT_TEXT As String = ""
Const NO_PICTURE_FOUND As String = "No picture found"
Dim picURL As String
Dim rowIndex As Long
Dim lastRow As Long
Dim data() As Variant
Dim wks As Worksheet
Dim Cell As Range
Dim pic As Picture
On Error GoTo ErrorHandler
Application.ScreenUpdating = False
Set wks = ActiveSheet
lastRow = wks.Cells(2, "B").End(xlDown).Row
data = wks.Range(wks.Cells(3, "C"), wks.Cells(lastRow, "C")).Value2
For rowIndex = 3 To UBound(data, 1)
**If StrComp(data(rowIndex, 1), EXIT_TEXT, vbTextCompare) = 0 Then GoTo ExitRoutine**
picURL = data(rowIndex, 1)
If Len(picURL) > 0 Then
Set Cell = wks.Cells(rowIndex, "A")
Set pic = wks.Pictures.Insert(picURL)
With pic
.ShapeRange.LockAspectRatio = msoFalse
.Height = Cell.Height
.Width = Cell.Width
.Top = Cell.Top
.Left = Cell.Left
.Placement = xlMoveAndSize
End With
Else
wks.Cells(rowIndex, "A").Value = NO_PICTURE_FOUND
End If
Next rowIndex
ExitRoutine:
Set wks = Nothing
Set pic = Nothing
Application.ScreenUpdating = True
UserForm.Hide
Exit Sub
ErrorHandler:
MsgBox Prompt:="Unable to find photo", _
Title:="An error occured", _
Buttons:=vbExclamation
Resume ExitRoutine
End Sub
我加粗是迫使它的「ExitRoutine」的路線。我不確定這條線是如何工作的，因爲我不是最初編寫它的人。任何幫助將是偉大的！
什麼'lastRow'失敗時的價值？一個簡單的測試將是'如果Len（data（rowIndex，1））= 0然後GoTo ExitRoutine' –
