Unit Testing: Mock Objects to the Rescue! Test Your .NET Code with NMock


The problem: unit testing libraries, especially data access components, that have a complex set of dependencies. The solution: providing a dynamic mock implementation of your data access classes. Here the author explains just how to make testing easier and more reliable using NMock.

Toolbox: Database job scheduling, Browser Analysis, and More


From a developer's perspective, once a database's schema has been defined and the tables, stored procedures, and other database objects have been created, it can be forgotten, abstracted away into the data access layer of the application's architecture.

Detailed documentation for toolbox objects


I have been developing application in Visual Web Developer 2008 Express using ASP.Net and Visual Basic.  My problem is finding documentation for each of the various toolbox "Standard" objects and the "properties" for these objects.   I have manuals that cover some of the more commonly objects  but I am hoping that somewhere there is a manual or website(s) that would provide detailed information on all (or most all) of these objects.   Does anyone know of a manual or website that provides this information.




Passing objects from Windows App build in .net 1.1 to WPF browser build in 4.0

Would it be possible to pass some values from windows application that is build in .net 1.1 to wpf browser application. Our requirment is to open a WPF brower application from a windows application. I believe that can be done by opening a wpf browser application to a new IE window. But I am not sure how to pass some objects as parameter to WPF browser application from windows form. Thank You

Cross browser Javascript Help ! (SWFObject)


Hey i have this JavaScript code:

function loadPlayer() {
	var params = {};
	params.allowScriptAccess = "always";
	params.wmode = "opaque";
	var atts = { id: "etPlayer", name: "etPlayer" };
	swfobject.embedSWF("etPlayer.swf", "etPlayerDiv", "640", "385", "10", "playerProductInstall.swf", null, params, atts);

function onetPlayerReady(playerId) {
	if (playerId && playerId != 'undefined') {
		etPlayer = document.getElementById('etPlayer');
		setInterval(updatePlayerInfo, 0.1);
		etPlayer.addEventListener('onStateChange', 'onPlayerStateChange');
		etPlayer.addEventListener('onError', 'onPlayerError');

function updatePlayerInfo() {
	// Also check that at least one function exists since when IE unloads the
	// page, it will destroy the SWF before clearing the interval.
	//alert("updatePlayerInfo() " + etPlayer); //returns updatePlayerInfo() [object]
	if (etPlayer && etPlayer.getDuration()) {
		if (gup("id") == "RSpfTbxXaf0") {
			if (etPlayer.getCurrentTime() >= 11.90 && etPlayer.getCurrentTime() <= 12.00) {

Unit Testing SharePoint - Past, Present, and Sporm

As I described in SharePoint: The Wild West of Software Development there is a serious problem when you develop for SharePoint: ensuring quality through unit testing is really, really hard. And that's where a new open source tool just released today called sporm (SharePoint Object Relational Mapper) comes in. While sporm provides many benefits besides simplified unit testing I wanted to focus on this topic first, because sporm's approach, which models the entity framework in the way it supports POCO's, is a unique feature not available with other SharePoint tools like LINQ to SharePoint.

How to setup a Mobile Browser Emulator in Windows Mobile 6:

In the following tutorial, I cover the process of Setting up Windows Mobile 6 for Mobile Browser Emulation using the Microsoft Device Emulator. This enables a user to experience Windows Mobile 6 on a PC via Emulation without even owning a Windows Mobile 6 product. It can be a great way to test drive Windows Mobile 6 before purchasing a product with it installed. In our case, it allowed us to Emulate Windows Mobile Browsing so that we could optimize our sites for the Mobile viewing audience. Installation and Emulation is simple and fairly straight forward.

Need help with objects and arrays

        Dim _hour As String
        Dim _impressions As String
        Dim _clicks As String
        Property Day() As String
                Return _day
            End Get
            Set(ByVal value As String)

            End Set
        End Property
        Property Hour() As String
                Return _hour

*.axd script references not being rendered to browser


I'm running VS2010 with .net 4.0, and am running into issues with the .net ajax script tags mysteriously not being rendered to the browser.

So far I've reduced it to a scenario where I set the DataSourceID property of a databound control.  More specifically, I've only tested it on a Gridview and a DropDownList.

This can be reproduced fairly easily on my machine by following these steps:

1. Create a new empty Web Application Project

2. Create a new Web Form

3. Add a ScriptManager inside the form

4. Add a DropDownList and a DataSource (I used an ObjectDataSource)

5. Set the DataSourceID property of the DropDownList to the ID of the DataSource.  This can be done either declaratively on the .aspx page, or in the code behind in the aspx.cs page, and both produce the same results.

6. Open the page in a browser and watch as you get a javascript error stating "Sys is not defined" and notice that the page source contains no script tags referencing *.axd scripts.

Here's my source code showing my set up:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ScriptResourceFAIL.Default" %>


WebDev.WebServer.exe has encounted a problem and needs to close when trying to view page in browser


Hi, whenever I load an aspx page in vwde2008, I get the message in the subject of this post.  After I click Ok on that, I get a dialog box, Unable to Connect to the ASP.Net development center.  What can I do to troubleshoot?

I am using Windows XP SP3, vwde2008 with SP1, on a HP desktop.  Also using Office 2003 if that is relevant at all.

Thanks, Justin

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?

How do I preserve __viewstate between cross domain posts or how do I get a __viewstate of a Remote S


Here is what I want to do:
I have a local site in which I want to display data from a remote site
Lets say: I want to display data of http://www.abc.com/Default.aspx on my localhost

Now Default.aspx requires some post-data which it sends to itself. Thus the __viewstate and __eventvalidation are posted back to it by itself. I want to directly post the data to Default.aspx from localhost without opening Default.aspx and display the Default.aspx's response on my localhost.

The WebApp on http://www.abc.com is configured for __eventvalidation i.e. I cannot post-data to it from my localhost without getting a __viewstate from it. I also have to post the current __viewstate of http://www.abc.com/Default.aspx to itself

How can I accomplish it?
