image to memory stream to MSpaint

Question

User59672602 posted

Hi,

 

I am trying to write an image to a memorystream and then read the bytes from the memory stream and open the file with Mspaint.  Below is what I have done so far.  Any help would be appreciated.

 

Try
            'MemoryStream stream = new MemorySteam();
            Dim stream As New MemoryStream()
            Dim fileName As String = "ChartPicture.bmp"
            Me.OlapChartcsi.Save(stream, fileName)
            Me.Response.Clear()
            Me.Response.AppendHeader("content-disposition", "attachment; filename=" & fileName)
            Me.Response.ContentType = "image/bmp"
            Me.Response.BinaryWrite(stream.ToArray())
            HttpContext.Current.ApplicationInstance.CompleteRequest()

            Dim oProcess As Process = New System.Diagnostics.Process()
            oProcess.StartInfo.FileName = "mspaint"

            oProcess.Start()

 

        Catch ex As Exception

        End Try

 To open de saved image with MSPaint, you have to add the full path to the filename in the oProcess.StartInfo.Arguments property.

Try to save it to "C:\test.bmp" and set the Arguments property to "C:\test.bmp" to find out what I mean.

If you want to load it in MSPaint without saving to disk, try setting the image data to the clipboard en use sendkeys to trigger a paste.
