Hi All,

Im having a hardtime to pass a parameter to below line.

'myEncoderParameter = New EncoderParameter(myEncoder, CType(20L, Int32))
      myEncoderParameter = New EncoderParameter(myEncoder, CType(xx, Int32))

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
    Dim xx As System.Int64
    xx = 20 & "L"
    Try
        If Not IO.Directory.Exists("C:\Folder\") Then IO.Directory.CreateDirectory("C:\Folder\")
        'Dim bit As Bitmap = CaptureScreen(0, 0, Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height)
        Dim myImageCodecInfo As ImageCodecInfo
        Dim myEncoder As Encoder
        Dim myEncoderParameter As EncoderParameter
        Dim myEncoderParameters As EncoderParameters

        Dim bit As Bitmap = CaptureScreen(0, 0, Screen.AllScreens.Sum(Function(s As Screen) s.Bounds.Width), Screen.AllScreens.Max(Function(s As Screen) s.Bounds.Height))

        myImageCodecInfo = GetEncoderInfo(ImageFormat.Jpeg)
        myEncoder = Encoder.Quality
        myEncoderParameters = New EncoderParameters(1)
        'myEncoderParameter = New EncoderParameter(myEncoder, CType(20L, Int32))
        myEncoderParameter = New EncoderParameter(myEncoder, CType(xx, Int32))

        'myEncoderParameter = New EncoderParameter(myEncoder, Fix(EncoderValue.CompressionLZW))
        myEncoderParameters.Param(0) = myEncoderParameter
        'myBitmap.Save("Shapes025.jpg", myImageCodecInfo, myEncoderParameters)
        bit.Save("C:\Folder\" & Format(Now, "yyyyMMdd hhmmss") & ".jpg", myImageCodecInfo, myEncoderParameters)
        bit.Dispose()
    Catch
        If Err.Number = "-2147467261" Then
            Exit Sub
        End If
    End Try
End Sub

What I have tried:

'myEncoderParameter = New EncoderParameter(myEncoder, CType(20L, Int32))
myEncoderParameter = New EncoderParameter(myEncoder, CType(xx, Int32))

What is the point to create an int64 variable if you already know that you will need an int32 value?
Have you tried:

VB.NET

Dim xx As Integer = 20
'' ...
myEncoderParameter = New EncoderParameter(myEncoder, xx)

If you really want to define an int64 in the first place, you should know that VB.NET does not use suffixes, as you can do in C#.
This would give somehing like:

VB.NET

Dim xx as Int64 = 20

This seems that you are trying to convert a code from C# to VB.NET without having a clear understanding of both languages and their differences; that's not a good idea :)
Kindly.
