Re: From C to VB.NET (Part III) (Background image in TextBox)

Tech-Archive recommends: Fix windows errors by optimizing your registry

1 this is not C but C#
2 you need framework 3 'cause it is WPF
3 you also have to copy the xaml code
4 it look like a custom WPF library project

I feel my delay. I had work.

First of all, thank you for reply.

I explain: I do not know use the code of the original web page in VB.NET.
Gillard made the translation from C (and thank you) but some things VB.NET
does not recognize them (for example, some "imports"). I do not also know use
the part of the code that begins for " <Page ... ", though VB.NET admits this
code if in front of every line write three characters of commentary ( ''' ).

If someone knows the method to realize this example in VB.NET I'll be very
grateful and probably many people because it is a code interesting (that
those of Microsoft might have written it also for VB).

Thank you very much again.

This is the code:
