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

    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:

      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

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

          Hello.

          I do not understand how works this of WPF, but I've created a new project to
          which I've added a WPF user control, but control Textbox not have a property
          to establish a background image. Nor does works the code example of
          Microsoft, or I don't know how to do it.

          Does any idea?

          Thank you.

                      because to make a WPF project you need some more stuff than just vb2005

                      Hello.
                      >
                      I do not understand how works this of WPF, but I've created a new
                      project
                      to
                      which I've added a WPF user control, but control Textbox not have a
                      property
                      to establish a background image. Nor does works the code example of
                      Microsoft, or I don't know how to do it.

                      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).
