You can put a PictureBox on the MDI form.

What version of VB?  I have VB6 and the MDIForm has a Picture property.

it doesn't have  a placepicture... i can put a picture on it but i need to know how to tile a small picture across it...vb 6
Bob LearnedCommented:
You are losing me, because my MDIForm has a Picture property, and you said that you know how to tile across a normal form.  

So what is the problem?
hessAuthor Commented:
but you can't tile on the mdi one cause to do it you need a place picture method on the form you want to do it on and the mdi form has no place picture property.
Éric MoreauSenior .Net ConsultantCommented:
You simply cannot tile a small bitmap on a MDI form.

Thera are at least 2 workarounds to this:
1 - My prefered one. Use a paint editor, tile your bitmap to cover an entire screen, save it and pur this new big bitmap in the Picture property of your MDI form. So there is no tiling just one big bitmap.

2 - But a child form in which you tile your bitmap and place code to be sure that the user won't close this form.

is there a way to tile the bmp on in a picture box... then set that pictures picture to the mdi form's picture so taht the mdi gets a tiled image?
Bob LearnedCommented:
Tile the image on a regular form, and then transfer the picture image to the MDIForm Picture property.

Private Sub Background()
Dim i           As Long
Dim j           As Long

   With Form1
      .Width = Width
      .Height = Height
      With .picBkImage
         For i = 0 To Form1.ScaleWidth Step .Width
             For j = 0 To Form1.ScaleHeight Step .Height
                 Form1.PaintPicture .Picture, i, j, .Width, .Height + 30
             Next j
         Next i
      End With
    End With
    Picture = Form1.Image
End Sub

Private Sub MDIForm_Load()

End Sub
'MDIForm:The name of the MDI parent form to tile an image onto.
'bkgdtiler: The name of a form that is used to generate the tiled background. Check the rest of the docs for the -required- parameters.
'bkgdfile: The image file to load, With complete path.
'The best place to put the call I find is in the form's Form_Load() event.

Sub TileMDIBkgd(MDIForm As Form, bkgdtiler As Form, bkgdfile As String)

    If bkgdfile = "" Then Exit Sub
    Dim ScWidth%, ScHeight%
    ScWidth% = Screen.Width / Screen.TwipsPerPixelX
    ScHeight% = Screen.Height / Screen.TwipsPerPixelY
    Load bkgdtiler
    bkgdtiler.Height = Screen.Height
    bkgdtiler.Width = Screen.Width
    bkgdtiler.ScaleMode = 3
    bkgdtiler!Picture1.Top = 0
    bkgdtiler!Picture1.Left = 0
    bkgdtiler!Picture1.Picture = LoadPicture(bkgdfile)
    bkgdtiler!Picture1.ScaleMode = 3

    For n% = 0 To ScHeight% Step bkgdtiler!Picture1.ScaleHeight

        For o% = 0 To ScWidth% Step bkgdtiler!Picture1.ScaleWidth
            bkgdtiler.PaintPicture bkgdtiler!Picture1.Picture, o%, n%
        Next o%

    Next n%

    MDIForm.Picture = bkgdtiler.Image
    Unload bkgdtiler
End Sub
