I’m converting some Foxweb stuff to asp.net. Starting with what I hope are some

  • 0

I’m converting some Foxweb stuff to asp.net. Starting with what I hope are some simple things to learn the techniques and will work on the harder problems later.

I have a case where I’m trying to use a function that is declared in another file. I anticipate this will be a common thing to do as it would probably not be put in a separate file unless it were used by (called in) separate files.

In my aspx file I have a line that looks like this:

Response.Write ( Globals.html_thingie("My Title") )

In another file I have written a class that looks something like this:

Public Class Globals
    Public Shared Function html_thingie(ByVal title As String)

        Dim str As String
        str = "<head>" &  title & "</head>" & vbCrLf
        Return str

    End Function
End Class

When I build the class (in Visual Studio) it gives no errors or warnings and creates a dll file called ClassLibrary1.dll which I copy to the same directory as the aspx file. I don’t know why it uses the name “ClassLibrary1” as I changed the solution name to “Globals” to match the class name and changed what I “think” is the project name to “clsGlobals”. In any case, I copied the dll to the same directory where the server keeps the aspx file. When I invoke the aspx from the web page, it fails. It will not tell me the error message for security reasons, but I suspect that there is something fundamental that I’m missing here.

Ideas?

    Here’s what I had to do.

    1. Putting a customErrors tag in system.web was extremely helpful. (thanks, dahrnsbrak)

    2. It does not like the term “Globals”, so I changed the name to clsCommon.

    3. Changing the assembly name was handy. (thanks again, mark)

    4. The system doesn’t care about (or apparently even use) the dll. I compile only to check for errors.

    5. It does use the vb file. So I copied clsCommon.vb to the same directory as my aspx file.

    6. There were a number of things I had to do inside the class file. Here’s a shorted, but final version of it.

      Option Explicit On

Option Strict On


Imports System

Imports System.Web.UI

Imports System.Web.UI.Page


Public Class clsCommon
    Inherits Page

Public Shared Function html_thingie(ByVal title As String) As String

    Dim str As String

    str = "<head>" & title & "</head>" & System.Environment.NewLine
    Return str

End Function

End Class

    7. I had to do the following in the aspx file to invoke this function.

    a. at the top of the file I added:

    <%@ page inherits="clsCommon" src="clsCommon.vb" %>

    b. The specific line to invoke the function was:

    <%
Response.Write ( clsCommon.html_thingie("Register for Course") )
%>
    1. In addition to your responses, I found the following page helpful:
