Need help in using C# application out put to vb.net application

Please check some articles.

Suppose that you have an image in C# app, and you want to transfer the image to VB.NET app, placed in PictureBox1.
If both applications runs in same computer, you can use Clipboard.

Code for VB.NET app:

Private Sub ReceiveImage(ByVal state As Object)
    Dim hWait As New System.Threading.EventWaitHandle(False, System.Threading.EventResetMode.ManualReset, "Global\ImageTransfer")
    Do
        hWait.WaitOne() ' Waiting signal from your C# app
        Me.Invoke(New System.Threading.ThreadStart(AddressOf GetImageFromClipboard))
        hWait.Reset()
    Loop
End Sub

Private Sub GetImageFromClipboard()
    PictureBox1.Image = Clipboard.GetImage()
End Sub

add this line in Form Load event:

System.Threading.ThreadPool.QueueUserWorkItem(New System.Threading.WaitCallback(AddressOf ReceiveImage))

To send an Image from C# app:

Image anImage;

Clipboard.SetImage(anImage);
// Tell your VB.NET app, there is an image in Clipboard
System.Threading.EventWaitHandle.OpenExisting("Global\\ImageTransfer").Set();

I am a little confused.
As I know, both C# and VB.NET in .net application are supported.
If you want to change the c# to vb.net , just need to rewrite it.
Here is an example:

Dim barcode As BusinessRefinery.Barcode.QRCode =
New BusinessRefinery.Barcode.QRCode()
barcode.Code = "QR Code"
barcode.Resolution = 104
barcode.Rotate = BusinessRefinery.Barcode.Rotate.Rotate270
barcode.Format = System.Drawing.Imaging.ImageFormat.Gif
barcode.drawBarcode2ImageFile("c:/qr-code-vb-net.gif")

Barcode Generator for VB.NET is a professional and flexible barcode generating component, enabling users to easily integrate dynamic barcodes into Visual Basic.NET development environments, including VB.NET ASP.NET & Windows Applications, VB.NET Class & Console Applications, SSRS for VB.NET and VB.NET Crystal Report.

Hope it helps!
