Unable to load data from txt file with text delimiter specified, if the data has the same character


Have come across a strange scenario and seeking your ideas/thoughts.

I'm using a ssis package to load a txt file. The txt file is text delimited by double quote (") and column delimited by tilde (~). It works fine in most scenarios and strips the enclosing "" from the columns -no problems there. However, in a specific scenario where the last column has double quote in the data as well being the text delimiter, the package throws the following exception indicating that it's missing a column delimiter

 The column delimiter for column "COL_NAME" was not found

This behaviour was not observed when double quotes were present as data in any other column in the file. Was able to workaround by disabled text delimiter only for the last column, but that isn't a perm solution. Also observed that if the " was replaced by escape sequence /" the file loaded successfully. Wondering if this a known issue ?

Could Not Load File or assembly 'MySql.data'



I am trying to test website on a remote server to see if I can read or write to a MySql Database.

In VS Web developer 2010 Express edition, I created a new website and saved it via ftp on the remote host. I have added the 'Mysql.data.dll' to the website and placed it in the bin directory of the project.

When I try to run the program i get "Could not load File or assembly MySql.Data, Version=, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The system cannot find the file specified.

Line 4:  		<compilation debug="true" urlLinePragmas="true">
Line 5:        <assemblies>
Line 6:          <add assembly="MySql.Data, Version=, Culture=neutral, PublicKeyToken=C5687FC88969C44D"/>
Line 7:        </assemblies>
Line 8:      </compilation></system.web></configuration>

The remote server supports .Net v2, so I have made my application focused on v2 framework.  I have tried similar code on my local machine and works fine.

Can anyone pls advice what I might be doing wrong?



Could not load file or assembly 'System.Data.SqlServerCe, Version=,...

We have an application that runs on both Windows Mobile and Desktop, both which are now using SQL Server Compact 3.5 SP1 as the database.  Everything is working great on the WM side in debug and runtime, but on the desktop side we are getting the following error.

"Could not load file or assembly 'System.Data.SqlServerCe, Version=, Culture=neutral, PublicKeyToken=3be235df1c8d2ad3, Retargetable=Yes' or one of its dependencies.  The given assembly name or codebase was invalid.  (Exception from HRESULT: 0x80131047)"

I do not get this error when I run in debug mode for the desktop app, but if we install the application to a Vista (32bit) or Windows Server 2003 (32bit) machine we get the error.  The only thing I can point at that is different between all the different machines we have tried this on is that it always works if Visual Studio is installed on the machine.  

Our current deployment method is to mark the System.Data.SqlServerCe ( reference to Copy Local=False and then we package the SQL Server Compact 3.5 SP1 installer with our installation program.  I have verified that the dll's are in the GAC with the correct version, but the application cannot find an assembly.  I have also tried copying all the sqlce*.dll files (a

Could not load file or assembly - Web Deployment Project



I have the following projects in a solution :

- A Web Application

- A Class Library

- A Web Deployment project

The Web Application compiles and run fine when I don't go through the Web Deployment Project. However when I try to use that, I get the following error:

Data: More Load, Less Code with the Data Enhancements of ASP.NET 2.0


A data source control is a server control that wraps some basic functions of a data source - be it a SQL Server database, an XML document, an Excel worksheet, or a sitemap description. Through the services of a similar component, data-bound controls can fetch data as well as insert new records or update and delete existing ones. Data source controls enable a consistent model across a variety of data sources and dramatically reduce the amount of code needed to implement a two-way data-binding scenario. This article provides an introduction to data source controls and other related data binding features.
