圖像框控件（VBA）中的圖像

Question

我正在尋找一種簡單的方法將圖像加載到excel中的userform，vba項目中的圖像控件。

是否可以直接從表單中加載粘貼的鏈接圖像，然后將該對象作為圖像控件的源？

我發現可以這樣做，但它需要導出圖像（或將圖像保存為圖像），然后將其加載到圖像控件，但我正在尋找一種不涉及excel文件中的外部數據的方法。

謝謝。

Answer 1

好吧，在用谷歌搜索后，我找到了這個解決方案：

對於示例，您將需要：

+----------------+----------------+
| Control        | Name           |
+----------------+----------------+
| User Form      | UserForm1      |
| Image          | Image1         |
| Command Button | CommandButton1 |
+----------------+----------------+

和2個普通模塊，我用這個名字：

+---------------+
| Module Names  |
+---------------+
| Functions_VBA |
| Image_Job     |
+---------------+

在UserForm1內部使用此代碼：

Option Explicit

Private Sub CommandButton1_Click()
    Paste_ThePicture 'I will explain later...
     Me.Image1.Picture = LoadPicture(thePath) 'Just this... load the picture
     'If you want to delete the picture from directory
     'Uncomment this:
     'Kill thePath
End Sub

在Image_Job模塊里面放了這個：

Option Explicit
Public thePath As String

Sub Paste_ThePicture() 'The procedure inside UserForm1
Dim fname As String
Dim objPicture As Variant

    With ActiveSheet.Shapes("Picture 1") 'The name of the picture inside the excel sheet
                                         'you can loop over the pictures or do somenthing
                                         'to take the picture you want
        .CopyPicture xlScreen, xlBitmap
        Set objPicture = PastePicture(xlBitmap) 'Store the picture inside the var
        fname = ThisWorkbook.Path & "\" & .Name & ".bmp" 'Create the path for the picture full path
    End With
    thePath = fname 'Store the full path to use it later
SavePicture objPicture, fname 'save the picture in the directory
                              'you can delete it later
                              'Look inside the userForm code
End Sub

魔術來了！ 在Functions_VBA里面放這個：

Option Explicit
Option Compare Text

有了這一切，你將：

打開UserForm1並單擊CommandButton1這將從ActiveSheet獲取形狀名稱“Picture 1”（它是您的圖片）並將其保存在Workbook的相同路徑中，然后，取出該路徑（存儲的圖片）並插入它進入Image1 。 如果需要，可以從路徑中刪除圖片。

我試着直接從剪貼板拍照，但我不知道是否可以，如果你能做到，請告訴我你是怎么做到的，現在這是我對你問題的幫助。

注意：我從這里拿出魔法代碼： Stephen Bullen

Answer 2

使用Elbert Villarreal / Stephen Bullen（Functions_VBA / PastePicture）提供的代碼，可以直接從剪貼板粘貼圖像（不將其保存到磁盤）：

Sub Paste_ThePicture()
    With ActiveSheet.Shapes("Picture 1")
        .CopyPicture xlScreen, xlBitmap
        UserForm1.Image1.Picture = PastePicture(xlBitmap)
    End With
End Sub
