Export Graph to jpeg/gif

[Basstion]

Hello,

How might I export the image of a graph to jpg/gif format using measurement studio for Visual Basic .NET?

If you have Measurement Studio 7.1, you can do this via the ToFile method. For example:

' Export to a .gif file
graph.ToFile("C:\Graph.gif", ImageType.Gif)
 
' Export to a .jpg file
graph.ToFile("C:\Graph.jpg", ImageType.Jpeg)

The graph is of type   AxCWUIControlsLib.AxCWGraph (not NationalInstruments.UI.WindowsForms.Graph) and does not have a toFIle function.

Sorry, I assumed you were using the Measurement Studio .NET Windows Forms graph since this was posted to the .NET forum. If you're using the interop wrappers to the Measurement Studio ActiveX UI controls, you can call ControlImage to get an image (metafile) of the graph, then you can save the image to a file via the Image.Save method by specifying a file name and either ImageFormat.Gif or ImageFormat.Jpeg. For example:

Dim controlImage As Image = Nothing
Try
    controlImage = AxCWGraph1.ControlImage()
 
    ' Export to a .gif file
    controlImage.Save("C:\Graph.gif", System.Drawing.Imaging.ImageFormat.Gif)
 
    ' Export to a .jpg file
    controlImage.Save("C:\Graph.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)
Finally
    If Not controlImage Is Nothing Then
        controlImage.Dispose()
    End If
End Try

Just out of curiosity, why are you using the interop wrapper to the Measurement Studio ActiveX UI controls rather than using the native Measurement Studio .NET Windows Forms controls?
