BUG: MSChart EditCopy Sends Incorrect Legends To Clipboard

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a Visual Basic Standard EXE project. Form1 is created by default.
2. From the Project menu, choose Components, which opens the Components dialog box. Click "Microsoft Chart Control", and then click OK.
3. Add a Chart control to Form1 and set the chart's ShowLegend property to True.
4. Add the following code to the General Declarations section of Form1:

         Option Explicit
   
         Private Sub Form_Load()
            ' Set the chart legends to some text value
            MSChart1.Plot.SeriesCollection.Item(1).LegendText = "Total Space"
            MSChart1.Plot.SeriesCollection.Item(2).LegendText = "Used Space"
            ' Call the EditCopy method to send the chart to the clipboard
            MSChart1.EditCopy
            ' Save the data on the clipboard as a bitmap
            ' you can also use clipboard viewer to see everything
            SavePicture Clipboard.GetData, "c:\test1.bmp"
         End Sub
   						

5. Run the program and the bitmap image of the chart control is stored in the file C:\test1.bmp.
6. Open the file test1.bmp using Paint, the Clipboard Viewer, or another image editor. The default values of the legend text were used rather than the values set by the sample program.

Steps to Workaround the Problem

1. Create a Visual Basic Standard EXE project. Form1 is created by default.
2. From the Project menu, choose Components, which opens the Components dialog box. Click "Microsoft Chart Control", and then click OK.
3. Add a Chart, a CommandButton, and a PictureBox control to Form1.
4. Set the ShowLegend property of MSChart1 to True.
5. Add the following code to the General Declarations section of Form1:

         Option Explicit
   
         Private Declare Function SendMessage Lib "user32" Alias _
          "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, _
           ByVal wParam As Long, ByVal lParam As Long) As Long
   
         Private Const WM_PAINT = &HF
         Private Const WM_PRINT = &H317
         Private Const PRF_CLIENT = &H4&    ' Draw the window's client area.
         Private Const PRF_CHILDREN = &H10& ' Draw all visible child windows.
         Private Const PRF_OWNED = &H20&    ' Draw all owned windows.
   
         Private Sub Command1_Click()
            Dim rv As Long
            ' Make sure picturebox is same size as the chart.
            With Picture1
               .Height = MSChart1.Height
               .Width = MSChart1.Width
            End With
   
            Picture1.AutoRedraw = True
            rv = SendMessage(MSChart1.hwnd, WM_PAINT, Picture1.hDC, 0)
            Picture1.Picture = Picture1.Image
            Picture1.AutoRedraw = False
   
            ' Sent the picture to the clipboard.
            Clipboard.Clear
            Clipboard.SetData Picture1.Picture
   
            ' Save the picture on disk.
            SavePicture Form1.Picture1.Picture, "c:\testpic.bmp"
         End Sub
   
         Private Sub Form_Load()
            ' Set our legends.
            With MSChart1
               .Plot.SeriesCollection.Item(1).LegendText = "Total Disk Space"
               .Plot.SeriesCollection.Item(2).LegendText = "Used Disk Space"
            End With
            Picture1.Visible = False
         End Sub
   						

6. Run the program and click Command1 to store the bitmap image of the chart control in the file C:\testpic.bmp.
7. Open the file testpic.bmp using Paint or another image editor. You can also use the clipboard viewer to directly view the clipboard contents. Since the bitmap was created using the image on the screen, the legend text appears correctly as part of the image.
