webparts & sqlclientpermission

A

António Pinho

Hi,

I have a big problem with an webpart/assembly. i'm trying to connect to sql
server but i get the error "Request for the permission of type
System.Data.SqlClient.SqlClientPermission, System.Data, Version=1.0.5000.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.". i've searched for
it and can't find a clear answer. but one thing i'm sure: permissions. if i
change the trust level in the web.config of the sharepoint portal that i
created to full, everything works fine.

can someone help me?

TIA


code of the assembly, web.config, wss_minimaltrust_Custom.config

webpart/assembly

protected override void RenderWebPart(HtmlTextWriter output)
{
String strConn =
"server=myserver;database=mydb;uid=myuser;password=mypwd;";
SqlClientPermission permission = new
SqlClientPermission(PermissionState.Unrestricted);

try
{
permission.Demand();
permission.Assert();

SqlConnection Conn = new SqlConnection(strConn);
Conn.Open();
Conn.Close();
Conn.Dispose();
}
catch (Exception ex)
{
output.Write(ex.Message);
}
finally
{
output.Write(" the end");
};
}

Try to add in web.config the SQL Assembly in the SAFE section:

<SafeControls>
<SafeControl Assembly="System.Data.SqlClient, Version=1.0.5000.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
Namespace="System.Web.UI.WebControls" TypeName="*" Safe="True" />
of course IISReset - don't forget where you are :)

Hi Mihai,

Thanks for your reply, but it didn't work. The error message is still there.
This is a default sharepoint installation, and a portal with just one site
(a blank site) on it. Any other suggestion?

Isn't there anyone that uses webparts with sql server, without raising the
trust level to full?



TIA

Try to add in web.config the SQL Assembly in the SAFE section:

<SafeControls>
<SafeControl Assembly="System.Data.SqlClient, Version=1.0.5000.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

of course IISReset - don't forget where you are :)

Hi,

I have a big problem with an webpart/assembly. i'm trying to connect to sql
server but i get the error "Request for the permission of type
System.Data.SqlClient.SqlClientPermission, System.Data, Version=1.0.5000.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.". i've searched for
it and can't find a clear answer. but one thing i'm sure: permissions.

if
i
change the trust level in the web.config of the sharepoint portal that i
created to full, everything works fine.

can someone help me?

TIA

You need to edit the wss_minimaltrust.config file.

Add:

<SecurityClass Name="SqlClientPermission"
Description="System.Data.SqlClient.SqlClientPermission, System.Data,
Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
/>

to the SecurityClasses section and

<IPermission class="SqlClientPermission" version="1"
Unrestricted="true" />

to the PermissionSet section with the attribute Name="ASP.Net"

If you're still having trouble, look through the
wss_mediumtrust.config for the SqlClientPermissions entries and try to
add them to wss_minimaltrust.config.

Be forewarned that it's possible that later patches to SPS2003 may
blow out your changes. There's a way to use a different file other
than wss_minimaltrust.config but I haven't looked for it yet.
