ADO.NET: Building a Custom Data Provider for Use with the .NET Data Access Framework


The System.Data.dll assembly in the .NET Framework contains namespaces whose base classes can be used to create custom data providers. These namespaces also define a number of data access interfaces and base classes that let developers create data providers that will interoperate with other custom providers. Using the ADO.NET classes Connection, Command, DataReader, and DataAdapter, writing a provider is easier than writing one for OLE DB. This article explains these classes and their implementation, and how they can be used to write a variety of different kinds of data providers.

Building a Custom Data Grid: Performing Ad Hoc Web Reporting with a VBScript 5.0 Class Object


A flexible, customizable grid for displaying data is a useful tool for ASP developers. It allows Web visitors to customize their view of your data. This article takes the data grid presented in "Ad Hoc Web Reporting with ADO 2.0" by John Papa and Charles Caison (MIND, December 1998) and adds handy features such as a finds feature that supports multiple finds and a mode for adding and editing records. This version also improves response time by allowing asynchronous record download and it componentizes the code so it can be used as a standalone VBScript class object that can be reused in other pages.

WCF issues sending large data - "An existing connection was forcibly closed by the remote host"

Hi Guys I have posted the following on www.asp.net but thought it might be productive posting here too.I have been pulling my hair out trying to fix an issue with sending data over WCF, I have read pretty much every THREAD on this forum regarding or similar to this issue without any successful solution.  I have a simple data object which has a [DataMember] with a data type of byte[]. I use this to send binary data from my web app as follows: Asp.net MVC website --> WCF Client (Has my Service References) --> My Services (MyServices.svc) --> Business/Data Tier Everything is being executed from within VS 2008 Pro.   Now I have successfully sent data up to 2.2MB, however it fails if i try and send a file such as 2.3MB or larger i get the following exceptions: General Exception Exception rethrown at [0]:    at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg)   at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)   at SoftApp.WCFClient.MyServiceReference.IMyService.Document_Save(DtoDocument dtoDocument, Int32 usercode)   at SoftApp.WCFClient.MyServiceReference.MyServiceClient.Document_Save(DtoDocument dtoDocument, Int32 usercode) in c:\dev\softapp\softapp.wcfclient\service references\myservicereference\refe

Facing MSDTC related issues while archiving data from one database server machine to another databas

I have a question with respect to distributed transactions when carried out between two database server machines on the same network.   Consider there are two database server machines \SOURCE_DATABASE_SERVER\ and \DESTINATION_DATABASE_SERVER\. Now we have to archive the data from one database server to other database server.   Let us suppose the database server \SOURCE_DATABASE_SERVER\ is the live production database server and \DESTINATION_DATABASE_SERVER\ is Long term storage database server. Now data from \SOURCE_DATABASE_SERVER\ needs to be archived into the database server \DESTINATION_DATABASE_SERVER\.   So I have written a dynamic stored procedure which includes distributed transaction (begin Tran, commit Tran, rollback            Tran) coding in it.   Now initially when I executed the procedure, it gave some of the following errors   1) OLE DB provider "SQLNCLI" for linked server "\DESTINATION_DATABASE_SERVER\" returned message "The partner transaction manager has disabled its support for remote/network transactions.". Msg 7391, Level 16, State 2, Line 1 The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "\DESTINATION_DATABASE_SERVER\" was unable to begin a distributed transaction.    

Data Import issues: Access 2003 .mdb to sqlce 3.5 on mobile device

I am trying to download wirelessly or cradled, data from 3 Access 2003 tables into my SQLCE 3.5 datatables.

VS 2010 and data source issues

I've been banging my head against the wall for the past 4 hours on this one and think I'm going to need a little help here. I must be missing something. I'm in VS 2010 on Windows 7. I've got a web project which has been going fine, but no matter what I do I can't get a data source to show up in the Data Source window. I've added a data source using Data > Add New Data Source, and the "wizard" appeared to complete successfully. I have a data source showing in my solution explorer, and if I open the .xsd file I see all my tables from a remote SQL 2005 database. I have a good data connection to the database server showing up in the Server Explorer window. But no matter what I do I cannot get anything to appear in the Data Sources window, which is greyed out (the commands at the top are grayed out and there's gray text in the middle of the window reading "There are no data sources to show for the selected project"). Under the main Data menu at the top of VS, the "Show Data Sources" and "Add New Data Source" commands are missing. I can sometimes get them to reappear if I restart Visual Studio or reboot the OS, but not consistently. I've been all over Google on this and have tried every suggested solution I can find, to no avail. Anybody have any ideas? Thanks.

Convert Data from TXT file and face a length issue! Need help!

Hi All, I am trying to convert some TXT files in to sqlserver database by using SSIS.  The problem I am facing right now is that some TXT files I have are fixed with line length 286.  However, for the some other TXTs they have 296 characters per line. The reason why this happened is some one added one more field before generating those TXTs.  Instead of creating two SSIS packages for converting those TXTs, can I find another way to get around this?   

SSIS Excel Connection Manager Data Type Conversion Issues with SS Agent Job

Hi All! I have an issue I've been trying to fix but can't seem to figure it out. I was hoping a kind person would point me in the right direction. :o) I have an SSIS package that uses an excel connection manager source, and I want to run this package through a job scheduled in the SQL server agent. The data types for the excel file fields are 2 (DT_WSTR) and 5 (DT_R8). When I run the package directly through the SSIS package (VS solution) all of the data fields are properly imported into the database table. But...when I run this package through the SQL server agent job, ONLY the string (DT_WSTR) fields in each row are being imported, all of the float fields are imported as NULL. I set the data types for these float fields as "float" in the SQL server import table (data type). Even though the excel source float fields are indicating a type of DT_R8 in the excel connection manager and I set the data types in the SQL server table to "float", I also used the data conversion component and set the type to "float" as a fail-safe. I guess I should add to that the data access mode in the excel connection manager is using a custom code to select only those columns that I needed and to trim rows that I didn't need. Here's my code that I have in the excel source editor: select f1, f2, f3, f5, f6, f7, f8 from [mdo$] where f2 <> 'Rep Name'

format-number issues with the Data View Web Part in SharePoint 2010

I have a number column named @Year_x0020_1_x0020_Revenue in the data view web part in SharePoint Designer 2010. In the Xpath expression builder - @Year_x0020_1_x0020_Revenue previews "500,000" If I use the format-number in the Xpath expression builder ==> format-number(@Year_x0020_1_x0020_Revenue, '$#,##0.00;-$#,##0.00'), it returns NaN. Is there any reason?
