Barcodes are not displayed on UserConrol

I decided to convert barcode generator from VB.Net (downloaded) to C #. There are two projects MSBarcodeCS (here the form) and Shtrikh_kod (and here UserControl ). The UserConrol should be displayed on the form, but not displayed. And do not tell me what the problem? Or are there any mistakes?

Here is the code:

And here is the form: Form1.cs
