Concurrency issue

I am currently trying to display multiple items on a single page. I am not sure as to how to tackle this. What I have is a database table that has all the page data in. I have this run as a PagesController and this works fine. However what I would like to do is, if say the Products page is selected via the menu, I want to pull back not only the Products page html but also get all the products, and even be able to pull them through via category. I was trying to use a partial view, but I can't get it to work. The same would be for other pages, having partial views to display the other content, ie if Gallery is selected, the page html for Gallery shows and it then can push to a partial view that pulls all the gallery images from the gallery db table and so on. 

Maybe I am tackling this the wrong way. I have the pages stored in the db to allow for a CMS system I have setup. Maybe I need to use models for all the other items(Products, Gallery, Videos and such) and use the partial for the page html?

Any help would be greatly appreciated as I am confused.

I have run into a problem with optimistic concurrency in my dynamic data application (where all relevant settings are at their default values); when I try to update or delete one of my tables, I see the following error:

 Exception type: ChangeConflictException
 Exception message: Row not found or changed.

I am the only user of my database at the moment, so I can guarantee that the data both exists and has not been changed outside the application!

Various forums have suggested that the way to deal with this is to set the column attributes so that the concurrency checking is disabled; i.e.

[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_PropSurname", DbType="NVarChar(255)", UpdateCheck=UpdateCheck.Never)]

However, to do this manually through the Visual Studio designer will take me hours (I have a lot of tables) and if I then change the schema of one of the tables in the DB, won't I then have to do it all again?  I've tried editing the .designer.cs file directly but my changes are subsequently overwritten (as expected).

All suggestions gratefully received!

Hi,

I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names.

So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".

But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.

-Thanks

I need the funcitonality to have two methods run concurrently of each other and the parent thread (aka the method that makes these two calls) to halt until BOTH are done. After the threads are done, I need to perform logic on the returns of the method, so it is essential for both of them to be complete before the parent thread continues. I have searched the internet and tried varous attacks, and I always come up with the same result, this being the parent thread continues operation after the first thread finishes, leaving the second thread running.  Can someone show me a quick example of how I can do this. I have tried checking states of the threads, halting the threads, but I always end up with the same thing. Any help would be great. Thanks.

Hi ,

I'm using Enterprise Library Logging  feature for logging. The issue i am facing is when the Logging message is too large(more than 65534 chars) ,complete data  is not logged in the Formatted Mesage column which is  of data Type nText .

I am able insert complete data if i try inserting from Sql insert Query from sql management studio. Do i need to add any attributes to data base listener or do i need to change the sp.

 Is there any way to increase the WriteLog stored proc param size in EnterpriseLibrary.Logging config file ? . Please let me know.

Thanks In Advance.

Hi,

The problem I am posting here is that I was facing nearly 2 weeks around. Any body comes with this stuff please help.

Word Automation in sample ASP.NET(C#) application.

I am using Microsoft.Office.Inetrop.Word Assembly for automation. Here I am reading a XXX.dot template file and fill the contents with dynamic data.

When i am executing my code in localhost:someportnumber the automation is working fine and I could get expected result and when I am hosting in my inetmgr(Windows XP is my OS) it is also working fine.

But the problem is that when I am hosting in my production server(Windows Server 2008 Standard Edition) I am not able to perform automation and results in the following error.

Data: System.Collections.ListDictionaryInternal
Message: Word has encountered a problem.
Source: Microsoft Word

The code gets failed in the following line:

ApplicationClass wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();

Document wordDoc = wordApp.Documents.Add(ref oTemplate, ref oFalse, ref oMissing, ref oMissing); // Error in this line

I cannot able to proceed further. Can anybody please help me in solving this issue?

Thank you.

Hi,

This is very strange to me. I have spent 2hrs looking into this inside out , but dont seem to get it

I have an if statement that inserts data into the database. But i check to make sure the name is not entered twice. Now when the name is already in the db, then it should insert else put out a message saying its already in the db

My code works fine except that  when its not in the db, its inserts but still puts out the message that says "Name is already in use" Not sure if am not seeing something. But thought i did bring it to the forum. Here is my code...Pretty simple

Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click

        Dim objConnection As SqlConnection
        Dim objCommand As SqlCommand
        Dim strSQLQuery1 As String

        ' If there's nothing to Add for then don't search
        ' o/w build our SQL Query and execute it.
        If String.IsNullOrEmpty(txtAdd.Text) Or Leadbank.SelectedValue = "000" Then

This article describes how to integrate the new parallel computing libraries in the Visual Studio 2010 Beta into existing C++ projects. Based on four common scenarios, the column explains a few of the ways developers can use the APIs and classes that are part of the Parallel Pattern Library (PPL), Asynchronous Agents Library, and Concurrency Runtime.

As more and more multi-threaded software applications get developed, software development professionals need to adopt new tools, techniques and metrics that can deal with multi-threaded software. Synchronization coverage is a simple, practical way to do this and this article covers a prototype synchronization coverage tool for .NET, called Sync Cover.
