Calling App_Code objects from classic ASP?

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :Windows Application

Anyone know if there is a way to create/call/use an app_code object in classic asp code?

For example, if I have a CaseStatus object in the app_code directory, how (or is it possible) for me to server.create this object and then call its methods from classic ASP?

Need help with objects and arrays


I have an objuct that I declared like this:

    Class DailyStats

        Dim _impressions As String

        Property Day() As String
                Return _day
            End Get
            Set(ByVal value As String)
                _day = value
            End Set
        End Property
        Property Hour() As String
                Return _hour

How to check for null/empty strings on dynamic objects?


What is the proper way to check for null or empty strings on dynamic objects? This is the only solution I've found so far:

if (admin.PasswordHash.GetType() == typeof(DBNull) || admin.PasswordHash == string.Empty)

If the field is null, the object returned is DBNull.Value, but if the field is empty string, it's return as a System.String object. This makes it impossible to do regular "admin.PasswordHash == DBNull.Value" check, as that will fail whenever the field has been set to empty string. Is my example the right (and only) way to go?

Calling webservice from the server


I have a sample web service and aspx file. I deployed them to an existing website that contains classic asp files.

web-service: --- using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Services; [WebService(Namespace = "http://localhost/MyWebServices/")] public class MembershipRegisWebService : System.Web.Services.WebService { public MembershipRegisWebService () { //Uncomment the following line if using designed components //InitializeComponent(); } [WebMethod] public string HelloWorld() { return "Hello World."; } }

aspx.cs file: --- using System; using System.Collections.Generic; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.Services; public partial class CallWebService : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { MembershipRegisWebService mrWs = new MembershipRegisWebService(); Response.Write("Calling web service:" + mrWs.HelloWorld()); } }

It runs locally, but it shows an error when running it from the server:

Server Error in '/' Application. Compilation Error Description: An error occurred during the compilation of a resource required to service this request. Please review the follow

Adding .net to classic asp


we have a classic asp site, which i'm adding all theses different mods to.
i really want to slowly move to .net, 
is it possible to keep the old base site in classic asp, and build up on it with .net?

Split URL/Path in Classic AND .net 2.0


I need to be able to get the different parts of the URI (and convert from/to relative page paths) in BOTH classic ASP and .Net 2.0 (VB).

For example, if I have "http://sitename.company.com/index.aspx?sec=fred&pag=dis&mode=1" OR "/index.aspx?sec=fred&pag=dis&mode=1"

IS there a function where I can pass in either string (assuming I'm on sitename.company.com) and get back an array with:

(0): sitename.company.com
(1): index.aspx
(2): sec=fred&pag=dis&mode=1

(Or, alternately, three different functions that would return the three parts?)

Class which contains an array of objects of type "Class2"



1  Partial Class _Default
2  Inherits System.Web.UI.Page

3 Public Function Ohjoy(ByVal X As Integer) As Integer
4 Dim theClass As New Class1 '= New Class1()
5    theClass.ReSize(0)
6    theClass.myBaby(0).GetName(0) = "Hello" 'Property Chars is read only'
7    Return 1
8 End Function
I have a first class named "Class1". I have a second class named "Class2" Class2, is a member of class 1,
and is implemented as an array of objects of type Class 2.

If I try and call the Accessor GetName() my hard coded value "Hello" in my accessor is not returned? Only
an alpha character like "T"

Also if I try and assigne a value using the setter GetName() it does not work, and the compiler gives me
an error message "property Chars is ReadOnly? Does anyone know what is wrong in my code? Line 6 above


Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
End Sub
End Class

Public Class Class1
    Dim bs As Integer
    Public myBaby() As Class2
    Public myB As Class2
    Public Function ReSize(By

Changing classic asp.net Menu to CssAdapterMenu


Hello Friends,

                     I have been using asp.net menu control that is programmatically binded at runtime and has n child node levels. Now i want to use CssAdapterMenu instead because the menu control contains more than 1000 menuItems(in the near future it can also be more 2000 menuItems) and has very slow response in IE 6 or IE 7.

                    Now my question is how should i change the classic asp.net menu to CssAdapterMenu. What should be the steps? Any samples example of n child node levels would be helpful
