: Hello!
: I'm new in VB. I have to use it because I have to do something  in Excel.
: My problem is to realize a simple drag and droop in a VB form.
: What I want to do? Simple. on the left site of my form should be some images 
: and on the right site will be  a shopping basket. For the user it should be 
: possible to drag the images and droop it in the basket. And how ever the 
: user does that, the program add something to the sheet.
: ...................

in my simple, i use the DSN to access the excel file

1��put 4 pictureboxs on the left site
2��set the dragmode to automitic in picturebox'attribute
3��put a listbox on the right site
4��add Microsoft Active Data Object Libary 2.8 reference

write these code on the dragdrop event of listbox
Private Sub lstCart_DragDrop(Source As Control, X As Single, Y As Single)
    Dim conn As New ADODB.Connection
    Dim strsql As String
    strsql = "Insert Into [SheetCart$] Values('" & Source.Tag & "','2',2,45)"  'the sql sentence for insert a record
    conn.Open "DSN=cart"                                                       'open database
    conn.Execute (strsql)                                                      'execute the command
    lstCart.AddItem Source.Tag                                                 'update the shopping cart
