I'm looking for a simple way to have an image loaded to the image control in a userform, vba project in excel.
Is it possible to load directly a pasted linked image from the sheet it self, and then have that object serving as source for the image control?
I found that it is possible to do so, but it takes exporting the image (or saving the image as image) and then load it to the image control, but I am looking for a way that does not involve external data from the excel file.
Thanks.
Well, after searching with google, I found this solution:
For the example you will need:
+----------------+----------------+
| Control | Name |
+----------------+----------------+
| User Form | UserForm1 |
| Image | Image1 |
| Command Button | CommandButton1 |
+----------------+----------------+
And 2 normal modules, and I use this Names:
+---------------+
| Module Names |
+---------------+
| Functions_VBA |
| Image_Job |
+---------------+
Inside the UserForm1 use this code:
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
Inside the Image_Job Module put this:
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
And the magic come heres! Inside the Functions_VBA put this:
Option Explicit
Option Compare Text

With all that, you will:
Open the UserForm1 and click the CommandButton1 this will take from the ActiveSheet the shape name "Picture 1" (it is your picture) and Save it in the same path of the Workbook, after that, take that path (the stored picture) and insert it into Image1.
If you want you can delete the picture from the path.
I try to take the picture directly from the clipboard, but I don not know if that is possible, if you can do it, please let me know how you did it, by now this is my help in your question.
Note: I take the magic code from here: Stephen Bullen
With the code provided by Elbert Villarreal/Stephen Bullen (Functions_VBA/PastePicture), it is possible to paste the image directly from the clipboard (without saving it to disk):
Sub Paste_ThePicture()
With ActiveSheet.Shapes("Picture 1")
.CopyPicture xlScreen, xlBitmap
UserForm1.Image1.Picture = PastePicture(xlBitmap)
End With
End Sub
