ComponentOne VSFlexGrid 8.0
Picture Property

Returns a picture of the entire control.

Syntax

val% = [form!]VSFlexGrid.Picture

Remarks

This property returns a picture (bitmap) representation of the entire control, including rows and columns that are not visible on the screen. If you have a control with 1000 rows, for example, the bitmap will include all of them, and the picture will be huge. To create a picture of a part of the control, write a routine to hide all the elements you don't want to show, get the picture, and then restore the control.

To reduce memory requirements for the bitmap and increase speed, you may consider setting the PictureType property to flexPictureMonochrome. The picture will not look as nice, but it will require less memory.

The example below shows a routine that creates a picture of the current selection.  It traps out-of-memory errors and automatically switches to monochrome mode if required.

    Private Sub CopySelectionAsBitmap(fg As VSFlexGrid)   

        ' save current settings

        Dim hl%, tr&, lc&, rd%

        hl = fg.HighLight

        tr = fg.TopRow

        lc = fg.LeftCol

        rd = fg.Redraw

        fg.HighLight = 0

        fg.Redraw = flexRDNone

   

        ' hide non-selected rows and columns

        Dim i&, r1&, c1&, r2&, c2&

        fg.GetSelection r1, c1, r2, c2

        For i = fg.FixedRows To fg.Rows - 1

           If i < r1 Or i > r2 Then fg.RowHidden(i) = True

        Next

        For i = fg.FixedCols To fg.Cols - 1

           If i < c1 Or i > c2 Then fg.ColHidden(i) = True

        Next   

        ' scroll to top left corner

        fg.TopRow = fg.FixedRows

        fg.LeftCol = fg.FixedCols   

        ' copy picture (with error-trapping)

        Clipboard.Clear

        On Error Resume Next

        fg.PictureType = flexPictureColor

        Clipboard.SetData fg.Picture

        If Error <> 0 Then

            fg.PictureType = flexPictureMonochrome

            Clipboard.SetData fg.Picture

        Endif   

        ' restore control

        fg.RowHidden(-1) = False

        fg.ColHidden(-1) = False

        fg.TopRow = tr

        fg.LeftCol = lc

        fg.HighLight = hl

        fg.Redraw = rd   

    End Sub
