<Id>0ZTNUiUrPECOfo+INVokdg=3D=3D</Id>Hi senthil:
What I've done in the past is use a tool like Fiddler [1] to compare
what my program is POSTing to the server versus what happens when I
use a browser.

System.Resources.MissingManifestResourceException: How to edit .resources file

I downladed skmMenu ( a 3rd party menu) for ASP.NET application and I have made skmmenu.dll . After that I putmenu control on my webform, and start my application.I get the following error in browser. I guess this is a library issue!! Can somebody help.

Could not find any resources appropriate for the specified culture (or the neutral culture) in the given assembly. Make sure "Menu.resources" was correctly embedded or linked into assembly "SkyMenu". baseName: Menu locationInfo: skmMenu.Menu resource file name: Menu.resources assembly: SkyMenu, Version=2.2.2078.30514, Culture=neutral, PublicKeyToken=null

Description:An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Source Error:

Line 1286:// If you are working on the skmMenu code base, this is in Menu.resx...Line 1287:ResourceManager manager = new ResourceManager( this.GetType() );Line 1288:script = manager.GetResourceSet(System.Globalization.CultureInfo.CurrentCulture, true, true).GetString("ClientScript");Line 1289:}Line 1290:this.Page.RegisterClientScriptBlock("skmMenu", script );

You need the Menu.resx file included in the dll's Project/Solution.
NC...

No Luck. Still getting same error.

System.Security.SecurityException: That assembly does not allow partially trusted callers.

I developed a web site using .net 2.0, mysql 4.0 and IIS 5.0. The server is hosted by a third party.

I am using the MySql.Data.dll library version 5.0.7.0 to connect to the database. I did not create any custom assembly and I am using the MySqlData objects directly from the code:

using MySql.Data.MySqlClient;

MySqlConnection conn;
MySqlDataAdapter data_retriever;
DataTable TextDataTable;

TextDataTable = new DataTable();

data_retriever = new MySqlDataAdapter(last_query_executed.Value.ToString(), conn);

data_retriever.Fill(TextDataTable);

This is the error I get:

System.Security.SecurityException: That assembly does not allow partially trusted callers.

My level of knowledge of .NET and Visual Studio is not advanced.

Do you have any suggestions?

Thanks,

Here is a post on the issue. It seems the current server configuration does not allow partial trusted callers.

http://bloggingabout.net/blogs/rick/archive/2006/04/07/11929.aspx -- this may not really apply becaus eyour site is hosted by a 3rd party

http://forums.mysql.com/read.php?38,95478,96748#msg-96748 -- has a link to download a new version of MySql assembly allowing partial trust. Not sure it will work, mixed results

http://forums.asp.net/t/999456.aspx -- has some other solutions. One of which is using a ODBC connection to MySql instead.

http://dev.mysql.com/tech-resources/articles/dotnet/ --see for ODBC driver details

I tried to recompile the library. However, I get a compilation error after I add the following line in the Assemplyinfo.cs:

[assembly: AllowPartialllyTrustedCallers]

Any ideas?

Christian

What error did you get? Also post your AssemblyInfo.cs file.

I fixed this problem, I was missing the following line:

using

System.Security;

however, now i am getting the error:

Unable to connect to any of the specified MySQL hosts.
