I made some changes to the Ads.xsd, and get the following error:
Error 101 Failed to generate code. Exception of type 'System.Data.Design.InternalException' was thrown. C:\Documents and Settings\ali\My Documents\Visual Studio 2005\Templates\ProjectTemplates\Visual Web Developer\Classifieds1\App_Code\DAL\Ads.xsd 1
btw, i just added a few columns, and changed the connection string.
here is the complete error:
Parser Error

I've had the exact same problem pop up on me over the years, and today I finally found out the cause. If you initially created the datasets by dragging and dropping from the Database or Server Explorer inside of Visual Studio, and the database reference
at some point is no longer valid (moved/deleted the database), it will cause this exception.
It's due to the fact that Visual Studio stores the connection string within the XSD. If that connection string is no longer valid, it can't dynamically generate the needed adapters. To fix this, change the ConnectionStringObject attribute on the Connection
node inside the XSD file (not at design level, but at the text editor level.) Set it to a valid connection string pointing to the database your dataset corresponds to, and you're good to go. Just right click on your dataset in the Solution Explorer, and
click "Run Custom Tool", and your problem should be fixed.
Hope this helps everyone else who is frustrated by this error message.
I tried putting the connection string in the ConnectionStringObject but I still get this error. Any other ideas?
I developed the site using my localhost db, but now I've changed all connection strings in the project (even in web.config) to the production db. Any idea why I'm still getting this same error?
I got the same problem when I move the website from one network to the another as I have 3 cn strings and I had to rename one of my cn string on the dev server. I got it fixed by adding a dummy TableAdpater --so you can verify you connection string and create
a new connection if you don't see the connection you had before. You can also right-click the DAL to bring up context menu, select 'View code' to compare the
<
Connections />
code before and after making the change.
well i had this problem too. Mine was an asp.net 2.0 web application using mysql as backend and i was using a dataset (with .xsd extension) to generate crystal reports . i cud solve this parser error problem in two ways:
1) I installed mysql.net connector on the machine u want to deploy on but this works if the connection string in ur dataset is valid.
2) or while making the dataset just dont drag the table from the server explorer as that would make the connection string.. make the dataset manually so this way a connection string wont come and populate the dataset at runtime with your own connection string
...and it worked
This was irritating me all over the place and would only show up when I tried to create a new table. Basically, I had the Oracle components installed from their site and had the tables defined in VS 2005 on an XP machine. When that machine had issues and
was upgraded to Win7 where VS2005 SP1 was installed, this was causing me all sorts of headaches.
All I did was to follow your advice and remove the connection string from the XSD file using Notepad, then did the "Run Custom Control" option and I'm back up now.

Getting same error. Not sure what is causing it. I created the DataSet yesterday and added a few tableadapters to it. Now today I get his message.

Is this the first time you've added any columns?
And did you modify the actual code in the ads.xsd file? (There's hidden code that makes it work)
Such as insertad, updatead relistad, all in the Ads.xsd code file.
Please remember to mark the post as answer that solves your issue.
This will be greatly benificial for other users.

Al reinstalar VS2005, y asumir que se usara el conector ya previamente instalado ocaciona este error,
La solucion es reinstalar el conector de MySql.
