Hi,

I have a real problem here. 2 weeks ago I upgraded to the latest version of the components (v2.70.3.0) and now I get the following problems but ONLY for projects that I originally built and compiled with the PREVIOUS version of the components (new ASP.NET and Windows forms projects work ok):-

1. I drop a MySqlDataAdaptor onto an ASP.NET page and select 'Configure Data Adaptor' from the properties page. In the properties window that appears I type in any SQL into the select command, hit OK and hit 'No' at the prompt asking if I want to regenerate the parameters. On hitting 'No' I get a message box telling that there are 'no suitable connections on form to use' even though there are!

2. I click on an existing MySqlDataAdaptor (one that I put on an asp.net page before the upgrade) and go to its properties window and expand the SelectCommand properties click on the elipsis button for the SelectCommand's parameters. When I click on the elipsis I get error 'Specified cast is not valid'.

3. When I compile the project after adding and removing data adaptors (trying to figure out the problem) a new task appears in the VS task list but the compilation still completes OK :-

Code generation for property 'Parameters' failed. Error was: ''MySqlParameterConverter' is unable to convert 'CoreLab.MySql.MySqlParameter' to 'System.ComponentModel.Design.Serialization.InstanceDescriptor'.'


I only noticed these problems yesterday because I've done no development for a few weeks.

I'm using VS 2003 and these problems occur on both of my development PCs. I've even loaded a backup of my project and it has the same problems. This is all a serious problem for me because have a big ASP.NET project that needs to rolled out in beta form this week! Any help would be greatly appreciated.

Many Thanks

Try to reinstall MySQLDirect .NET. Check before that MySQLDirect isn't installed and there are no CoreLab.MySql.dll, CoreLab.MySql.Addin.dll, CoreLab.MySql.Design.dll files in GAC.

I'm Running 2.80.5.0 and am getting the same result as above. It's not totally crippling. I just want it fixed. I have tried reinstalling, ensuring the GAC is clear and other items in the forum. How can I get the Data Adapter working?

1. Open "Configure Data Adapter" dialog.
2. Run new instance of Visual Studio and attach to process of first Visual Studio (where you opened "Configure Data Adapter" dialog) (menu "Tools"/"Debug processes").
3. Select "Common language runtime" option in the "Attach to process" dialog.
4. Open "Modules" window (menu "Debug"/"Windows"/"Modules").
5. Ensure that all "corelab*" modules have 2.80.5.0 version.
6. If some modules have another version note their paths and delete them after both instances of Visual Studio are closed. Reinstall MySQLDirect .NET.
