Migrating from ASP.NET 1.x to ASP.NET 2.0

Migrating portal app in .Net 1.1 to 3.5 - portal architecture issues

pblecha — Mon, 30 Nov 2009 21:25:52 GMT

I am migrating a web application that was built on the old IBuySpy portal technology over to .Net 3.5. Because of the amount of secure, dependent code, I'm having quite a bit of difficulty managing this migration. Here are a few points to start with (I'll have more as I'm going along, so thanks in advance to everyone who manages to help me with this):

The IBuySpy portal code made the management portal a separate solution and web application; however, because these applications are feeding from the same database layer, they need to consume the same web.config, as well as several data layer classes. In the past, this was done by inheriting the namespace from one portal to the other; but since web apps no longer build DLL files, I can't just import the DLL from one app into the other. I'm trying to incorporate all the changes into a new project that both web apps can then inherit from; but the crucial bit of info is the connection string in the web.config of the non-management portal app.
I want to "nest" these apps, so that the management side is a virtual directory under the main app; that might actually solve the first problem as well, but I need to do it in VS2008, not in IIS, so that the namespaces will be shared.
I also have an old-style web service that's not yet ready to be migrated to 3.5 code (I'm not in a position to make time for a complete development project here!), that also needs to be a virtual directory under the main app, and also share the web.config.

I've seen one, and ONLY one, website that mentions nested web apps, and it's messy as h3!!. Is there an easier, smarter solution to migrating these three separate apps into one without creating all sorts of new problems?

ConfigurationSettings.AppSettings obsolete

Robbied81 — Sat, 12 Dec 2009 23:31:06 GMT

I am going through some E-Commerce exercises in .NET 1.1. I just wanted to know if this code I have below is equivalent to the code in 1.1, as I was getting error messages regarding code being obsolete

.NET 1.1

Public Class Catalog

Private Shared ReadOnly Property connectionstring() as String

Get

Return ConfigurationSettings.AppSettings("ConnectionString")

End Get

End Property

End Class

.NET 2.0

Imports System.Configuration.ConfigurationManager

Public Class Catalog

    Private Shared ReadOnly Property connectionString() As String

        Get

            Return ConnectionStrings("ConnectionString").ConnectionString

        End Get

    End Property
End Class

"The base class includes the field 'WebUserControl1', but its type (common_WebUserControl) is not compatible with the type of control (ASP.common_webusercontrol_ascx)"

net_prog — Tue, 07 Feb 2006 19:41:50 GMT

Hello.

I tried to convert a project from ASP.NET 1.1 to 2.0 and found one big problem which stops the whole process.

An .aspx page from the subfolder "admin" includes a user control from the subfolder "common". Both subfolders ("admin" and "common" are in the root).

root
- admin
-- aspx page
- common
-- user control

The page works well when started from Visual Studio, but when the project is precompiled for deployment, the next error occurs:

"The base class includes the field 'WebUserControl1', but its type (common_WebUserControl) is not compatible with the type of control (ASP.common_webusercontrol_ascx)"

I tried to use "Reference" in the .aspx page, but that doesn't work.

Does anybody know any workaround for this?

Assemblies in web.config file creating problems

cplusplus1 — Wed, 09 Dec 2009 15:09:31 GMT

I migrated my 1.1 based project to 2.0 framework, when i did that it created all assemblies under web.config.

It started giving problems, including small things like CHR(34) it is saying CHR is not defined. also VBNULLSTRING etc.

When i removed those assemblies then it started working / recognizing.

What is the use of these asemblies in web.config file:

Got lost going from VS 2003 to VS 2008

dcwmorley — Fri, 16 Oct 2009 19:32:11 GMT

Secure Log-in using VS 2008

(A) In VS 2003 I created \Secure. Then in solution explorer I left buttoned the pages
I wanted to hide (say, for example, Page21 and Page22) into \Secure.

( I Can't do this in VS 2008 you can't drag with left mouse button anymore - what should I do ?)

(B) I added a page login.aspx and login.aspx.vb with suitable code to compare paswords etc. Then I also dragged login into \secure

(C) At the top of login.aspx.vb I added <code> Imports System.Web.Security </code>

(D) I added a first snippet to web.config

<code>

<authorisation mode="Forms" >
<forms name="Page21" login="secure\login.aspx>
<forms name="Page22" login="secure\login.aspx>
</authorisation>

</code

(E) I added a second snippet right at the bottom so that the end of web.config read

<code>

</system.web>
<location path="Secure">
<system.web>
<authorization>
<deny users = "?"/>
</system.web>
</loation>
</configuration>

</code>

At the moment web.config confuses me a lot. It's nothing like the VS 2003 version
which I more of less understood. Even when I collapse some of the sections I need a map.

I'm not sure what to put in the new web.config, and where to put it.

Questions are : How do I get login, Page21 and Page 22 inside \Secure ?

and

what should be in web.config and where should it be ?

and

Is there anything else I need ?

Hi All,

does anybody know a way to convert a .NET 1.1 application to .NET 2.0 version? Basically I want the current application that opens and compiles in visual studio 2003 to open and compile in visual studio 2008.

Any help would be great!!

migrated webapp from .net1.1 to 3.5 (now dropdownlist have duplicate items, and some controls render double)

VizualG — Tue, 17 Nov 2009 08:50:56 GMT

Hi everyone,

So my new boss asked me to migrate there old 1.1 webapp to .net 3.5, so thats what i did.
The conversion succeeded without any errors, just a few warnings about some obsolite classes (system.web.mail)

The real problems came when i first fired up the now .net 3.5 webapp,
almost all dropdownlist have duplicate items, some gridviews get rendered double.
And most other listview and sub menu's also have duplicate items.

It's almost like every control gets rendered/databound twice, or some kind of double viewstate consists.
Upon looking over the source codes i noticed that most of the Viewstate was controlled in de code-behinds,
almost like the first programmeur used the viewstate like some sort of session or chache object
reading and writing to the viewstate, but disabling it on the control it self.

I myself started programming asp.net c# from version 3.5 so i have no past experience about .net 1.1
the sources are way to big to include here, but just maybe i'm not the first one this happend to
and so maybe someone here could help me find a solution to this problem...?

thnx,

Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl).

InNeedOfAssistance — Thu, 05 Nov 2009 22:09:06 GMT

For the life of me I can't figure out what is causing this error. I have copied and pasted the namespace and the class name into inherits on the .aspx page. I had this compiled and working but now since I switched my development PC to Visual Studio 2008 on a Windows 7 OS, I can no longer compile. I don't have any old code with section12.PicturesAjax in it. Hopefully you'll see what I'm missing and clue me in. Help!

PicturesAjax.aspx code:

<%@ page language="c#" autoeventwireup="true" inherits="section12.PicturesAjax" CodeFile="PicturesAjax.aspx.cs" Codebehind="PicturesAjax.aspx.cs" %>
<html>
<%=pageContents%>
</html>

PicturesAjax.aspx.cs code:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace section12
{
    partial class PicturesAjax : System.Web.UI.Page
    {
      public string pageContents = "";

      protected void Page_Load(object sender, EventArgs e)
      {
        // This code opens an .asp picture page and strips out the code from body beginning to end body
        .
        .
        .
        pageContents = code stripped from .asp picture page
      }
    }

Use membership provider?

new2aspdotnet — Mon, 04 Aug 2008 23:03:40 GMT

Hi,

We are moving from ASP.Net 1.1 to 3.5 (yup, no 2.0).

I would like to know if we can use the Membership provider. We use SQL Server 2000. And we already have our Users table and associated sprocs, we cannot change the table design. From my little research, it looks like we cannot use the Membership provider. I just wanted to confirm.

Thanks.

I have a web service that has worked fine in an older Visual Studio 2003 version.
I am trying to add it an an upgraded Visual Studio 2005 Web Applicaiton and having some issues.

I can add the Web Reference and see the Service, its Disco, WSDl and what it calls the reference.map and reference.vb file all within the folder.

I can refer to the Web reference in code with no issues... i can also right click and do a "Go To Definition" and return to associated VB file associated to the Web Refernce.

When I go to run and compile the Web Applicaiton I get the following error.

Compiler Error Message: BC30002: Type 'DecryptTokenService.DecryptToken' is not defined.

is there some compile setting or something in the Web.config I am missing?

Sample usage of ClientScriptManager.RegisterForEventValidation

n33470 — Mon, 12 Dec 2005 18:59:13 GMT

Hi all,

I have a dropDownList on a web page that is populated by client-side
script. I get an error on PostBack of the page. I've seen quite a few
posts about this, so I understand the issue, and why it's occurring. I
know that I need to remove the automatic event validation that ASP.NET
is performing on the control. One of my options is to use the page
directive enableEventValidation="false". I'd rather not do this for
the entire page, I'd rather remove the event validation for only the
dropdownlist.

I've read that ClientScriptManager.RegisterForEventValidation can be
used for this. However, I haven't been able to figure out exactly how
to do it. I have overloaded the Render() method like this (the
object cboLookup is the DropDownList):

protected override void Render(System.Web.UI.HtmlTextWriter
writer)
{
base.Render(writer);

this.Page.ClientScript.RegisterForEventValidation(cboLookup.ID);

}

However, after doing this I still have the problem when the page is
posted back. I think I'm missing an extra step here, but I can't
figure out what it is. The method name is called
"RegisterForEventValidation", however I actually want to un-register
the control from ASP.NET event validation. How do you do this?

Can someone provide a simple example of how to bypass the automatic
event validation code on postback of the page for a single control.

from .net 2.0 to .net 3.5

aakbar — Tue, 13 Oct 2009 10:11:10 GMT

Hi,

I have recently moved from .net 2.0 to .net 3.5 framework. also i have upgraded my development environment from VS 2005 to VS2008. .net 3.5 framework was installed by VS2008 setup but it did not removed earlier version of .net. Means if i go into add remove programs i can still see .net 1.1, 2.0 and 3.0. Also if i go into GAC i can see multiple assemblies there.

my question is that if all our application are running in .net 3.5 would there be any assembly in GAC with earlier version. if not i could not find following assemblies under .net 3.5:

system.xml

system.windows.forms

system.web.services

system.web

system.security

system.data

and few other, all the above files are of version 2.0

does it mean .net 3.5 is incomplete without earlier version ..........

please help me to understand the concept.

thanks

.Net Framework 2.0 Upgrade Error : OracleClient requires Oracle client software version 8.1.7 or greater

Dejabu2009 — Wed, 30 Sep 2009 18:13:48 GMT

Recently I upgraded the whole application from .Net Framework to .Net Framework 2.0.

Also we migrated from Visual Studio.Net 2003 to 2008.

After making all the changes to the whole site, now when the application is trying to connect to Oracle 10g database, I am getting the below error message.

"OracleClient requires Oracle client software version 8.1.7 or greater"

The IIS Web Server Oracle 10 Client. I can log in to SQL plus from this machine. TNS entry is fine.

I also have the old Web application (.Net Framework 1.1) running fine from this Server.

Any help to resolve this issue, will highly be appreciated.

Make sure that the class defined in this code file matches the 'inherits' attribute, and that it extends the correct base class (e.g. Page or UserControl)

brian.wenhold — Tue, 29 Nov 2005 18:23:42 GMT

Here is the page directive for the page that throws the error:

<%@ Page language="c#" Inherits="University.AspNet.Index" CodeFile="Index.aspx.cs" %>

The code behind file Index.aspx.cs starts like this:

using University.Framework.UI;

namespace University.AspNet

{
public partial class Index : University.Framework.UI.HomePage

The code behind is extending this HomePage class, which is in turn an extenstion of another class University.Framework.UI.Page, which extends the System.Web.UI.Page class.

Am I misusing the Inherits parameter somehow?

Oddly there is a blue squiggle under only the first 'i' in University in the code behind that links to the error in the subject of this post.

Any insights as to the nature of this error would be greatly appreciated. Thanks.

Anyone has an idea of what it could be the problem?

Hi,

I just tried migrating an asp.net project that I wrote in Visual Studio 2003 years ago to a visual studio 2008 project. I went through the conversion wizard and to my surprise, it worked without any errors or warnings. I would have thought that at the very least there would be something about the DataGrid no longer being supported, but there were no problems.

Because it's been so long since I've looked at this app and because it has no logging of any kind, I'm not sure I know how to do a good job testing it top to bottom. So to those of you who are more experienced with migration, are there any common issues that I should watch out for? Any specific tests I can run? How do I make sure there are no compatability Easter eggs?
