Update statement with CASE inconsistently updates VARCHAR column, stripping leading zeroes.


I have an update statement below that strips the leading zeroes off the front of AU. This value will have typically '0001234' or something like this. In my case statement, I have 2 scenarios: 1) when I use the commented out phrase (case when 1=1), the statement leaves AU alone as it should when the condition is met. 2) When I use the other statement, it STRIPS the leading zeroes off AU - I don't want it. I am just telling it to set it as is. Why is this doing this and what can I do to stop it. I was just attempting to set AU = AU in these conditions.

CASE WHEN NullIf(MSDN.MSDN_Import1.LOBCC,'') IS NULL            -- when I use this line, AU='0001234' becomes AU = '

ASP.Net Gridview Edit Update Cancel Commands

In ASP.Net 2.0, GridView Control also provides the functionality to edit and update the data retrieved from the database using CommandField template. You can cancel the action using Cancel Command of the CommandField. GridView consists of events that can be used to perform the actions like edit, update and cancel upon the Data items displayed in the ASP.Net GridView Data Control.

How to format and update GridView and DataGrid rows using JQuery

The behavior described in this question is as expected. When you set text of a cell in grid, it directly affects HTML that is going to be rendered. When you set text value of a cell, it means that you are setting innerText of the cell. The column that GridView creates for command fields (Edit, Delete and Select) are a (anchor) or button elements. So you can see what will happen if you set text value in that cell. It will wipe out those link or button controls and replace them with simple text string.

ASP.NET Architecture - ASP.NET Worker Process - HTTP Pipleline - Http Modules and Handlers

"ASP.NET is a powerful platform for building Web applications, that provides a tremendous amount of flexibility and power for building just about any kind of Web application. Most people are familiar only with the high level frameworks like WebForms and WebServices which sit at the very top level of the ASP.NET hierarchy. In this article I'll describe the lower level aspects of ASP.NET and explain how requests move from Web Server to the ASP.NET runtime and then through the ASP.NET Http Pipeline to process requests.

Update Vs SystemUpdate

Many of you might noticed that share point ListItem has Update() method as well as SystemUpdate().

What is the difference between these two methods and why MOSS has two different APIs for updating an ListItem

SqlCommand.ExecuteNonQuery() returns -1 when doing Insert / Update / Delete

Sometimes you end up with a return value of -1 when using the SqlClient.SqlCommand.ExecuteNonQuery method.

Why is that?

Well, the ExecuteNonQuery method is there for statements for changing data, ie. DELETE / UPDATE /INSERT, and the returned value are the number of rows affected by that statement.

When checking the documentation we can see that there are some conditions that return -1.

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command.

When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of

rows affected by the trigger or triggers. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.

>>>How to update multiple rows of gidview by one click



I want to add multiple rows of a gridview if the data for multiple fields are same.

Idea for this is that a user may search a record with some parameter e.g. Sector, plot.

For example 15 records being displayed in gridview.

There should be checkbox before every row and if user wants to update Plot and Flat No that is same for 10 rows out of 15 so he will check the rows and update.

For this a dialog box should appear asking for the parameter i.e. Plot and Flat or something else next time may be it will be City or country. Moreover, there is already an Edit button to update records, when user click it another page open for the record to be updated and whatever he wants to update, it updates.

Hope everone understand the scenario.

I don't want to disturb the already provided Edit functionality and want to provide same record to be updated.

Any idea in this regard would be appreciated.

Visual Studio closes itself by opening aspx-Page designer after Windows Update


Hey Guys,

I've a problem with my Visual Studio.

On the 13th of August 2010 i installed a Windows update on my vista sp2 pc. For this date my Visual Studio 2008 sp 1 always has closed itself by opening an aspx-page in designer view. There is no error message just closing the window. I restored a backup of my windows from the time before updating it and it helped, i could open aspx pages in the design view till the update has been installed again automatically after rebooting the pc. I can't disable windows updates, cause it's my pc at work and safety is very important. I hope you could help me out of this disaster.



HTTP Error 403 - Forbidden


(VB Express website directed me to ASP.NET Web Services which in turn redirected me to this forum).

 Hopefully someone can help me here...... 

I am using VIsual Web Developer and downloaded the small business application to use as a starting point to help my wife get a website up for her small business. When I load the application, I can F5 and it runs fine but as soon as I make any modification to the app and hit F5, I get the HTTP Error 403 - Forbidden when it tries to show the website.

I notice a pop up that occurs when I run that allows me to choose the link for my app and it displays correctly (I close the webpage that has the error on it).

This seems like a pain, is there a setting I'm missing - I would think that this should "just work".

What's up?????

HTTP Post and WebService


I am working on a application which will accept the data in the post request. My application also wants to expose a web service and want to call another web service. Considering all these 3 action that I want to do, can I create a single application which will have a web form which will accept the POST request and expose a web service at the same time.

Although it may be possible to achieve this, Is this a correct way of doing it?
