i don´t know why.
Could you please help me with this problemHello, there must be some code you're using that is generating this error, could u please post the whole error ? and some code that might be generating this error !!!
This is what I am doing. we had an app that was written in VB to take
specific dates and create an excel file.
I am using the dll in my .NET app but it displays the error while writing
the file...
I am sure that I have used regsrv32 to register the DLL
any suggestions,
Stephenyou said you are using the COM server DLL directly in .net? If thats
what you are doing.. you need to create an interop assembly before you
can access the methods in that dll
Please let me know if I understoof your question incorrectly

If you're not attempting to run the applicaiton over the network, could you
please post the complete exception details (including call stack listing),
as returned from its ToString method?

This is how I am working on this project. I have a DLL given to me by
another developer that generates Excel files and he created it using VB6.
I registered it on my box, referenced it and I am trying to use it
This is the error I am getting along with stack trace:

Does the ASPNET user, which ASP.NET runs under, have permissions to the Access database?
NC...
Your site is working in a medium trust or even low.
If you are hosting the site with a company then you have to ask them to increase the trust level. If you are running this in your server, then you should know that when you use OLD DB, this is out of the medium trust privileges. You can get that working with some modifications in the maching.config and web.config if you are using ASP.NET 2.0
Check the following articles at servertastic
http://www.servertastic.com/articles/category/aspnet/
Let me know if you need further info

You have GOT to be kidding me...
Here's a snipped stack trace:
[SecurityException: Requested registry access is not allowed.]

System.Diagnostics.EventLog.CreateEventSource(String source, String logName) +41
Thanks for any help,
You have to give the ASP.NET porcess account access to modify the event log entries. There are a number of KB articles about this and related issues. Might start here:

You have GOT to be kidding me...
Wow, so you'd be cool that the Windows Registry gave access to running code by default?
Can you image the havok created if someone had a third party dll in their web project or some other made-with-.NET programming running that was reading and reporting EventLog details back to some remote server somewhere?
Explicitly setting the permission is absolutely the best route there.... protects programmeres/end-users fromthemselves
The EventLog is the central logging facility for Windows. Duh? Let my .NET applications write entries without bothering me with these overly paranoid, annoying details. This has just been one more delay in what should have been an easy development cycle...
By the way: "If you don't have anything nice to say or constructive to add, KEEP IT SHUT!"
There's a definite security concern with allowing the .NET process to write to the Windows event logs. The proper method would be to create your own event log for your app and write to that. In all cases never allow access to the secuirty log, makes it too easy to cover your tracks when you're hacking.
As long as you're comfortable with allowing the access, it's fine with us. If you wish to avoid further delays in your development cycle due to security issues, I suggest you make the group Everyone a local administrator and change all your processes to use the Administrator account. That way you pretty much won't be pestered by security issues in your coding.

Now that's funny! What a blissful world we'd all live in if everyone everywhere did exactly that! (tongue in cheek)
I followed the following article and I still get the error:
http://support.microsoft.com/defaul...kb;en-us;329291
Any suggestions?
ThanksWhen you say write to the registry, do you mean using the EventLog? Or do
you mean explicitly writing to the registry? The account that your ASP.NET
code is running as needs the rights to do whatever you're trying to do. Under
IIS5 it's the local ASPNET account. Under IIS6 it's the local Network Service
account.

Actually the problem was that I did not creat the Installet class properly
so Gacutil was unable to create the right permissions for my ASPNET user.
Thanks for your help

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.

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.
I am using .net 2. I have a key and use the regasm tool after it the
dll is compiled
I am really lost on how to make this work any help will be appreciated
Johnyou prolly have to add this to your code:
[assembly: AllowPartiallyTrustedCallers]
