我正在寻找一种简单的方法将图像加载到excel中的userform，vba项目中的图像控件。
是否可以直接从自己的工作表中加载粘贴的链接图像，然后将该对象作为图像控件的源？
我发现可以这样做，但它需要导出图像（或将图像保存为图像），然后将其加载到图像控件，但我正在寻找一种不涉及来自外部数据的方法excel文件。
感谢。

好吧，在用谷歌搜索后，我找到了这个解决方案：
对于您需要的示例：
+----------------+----------------+
| Control | Name |
+----------------+----------------+
| User Form | UserForm1 |
| Image | Image1 |
| Command Button | CommandButton1 |
+----------------+----------------+
和2个普通模块，我使用这个名字：
+---------------+
| Module Names |
+---------------+
| Functions_VBA |
| Image_Job |
+---------------+
在UserForm1内使用此代码：
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模块中放置了这个：
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
魔法来了！在Functions_VBA里面放了这个：
Option Explicit
Option Compare Text

有了这一切，你将：
打开UserForm1，然后点击CommandButton1这将取自ActiveSheet形状名称“图片1”（这是您的图片）并将其保存在相同的路径中Workbook之后，取出该路径（存储的图片）并将其插入Image1。
如果需要，可以从路径中删除图片。
我尝试直接从剪贴板拍摄照片，但我不知道这是否可行，如果你能做到，请告诉我你是怎么做到的，现在这是我对你问题的帮助。
注意：我从这里获取魔法代码：Stephen Bullen

使用Elbert Villarreal / Stephen Bullen（Functions_VBA / PastePicture）提供的代码，可以直接从剪贴板粘贴图像（而无需将其保存到磁盘）：
Sub Paste_ThePicture()
With ActiveSheet.Shapes("Picture 1")
.CopyPicture xlScreen, xlBitmap
UserForm1.Image1.Picture = PastePicture(xlBitmap)
End With
End Sub
