the error i'm getting after moving the aspnetdb db for the login control from vs to my iis for testing, see below for how i made the move attach the vs2005/app_data db to the sql express studio, there you can add the myMachine/aspnet user to the sql security users and then the users for the db, and give it db_datareader and db_datawriter permissions. then make sure that both the aspnetdb.mdf and its aspnetdb_log.ldf files have r+w permission for the aspnet account. then copy both files to app_data directory under the application folder in iis.

View 3 RepliesI have a c# website that allows a client to connect directly to a remote SQL Server database from their PC, bypassing the web server, by using a 3rd party ActiveX control. I was originally using the SQLOLEDB provider and it was working fine. The clients are in an internal network (using Windows machines and Internet Explorer) and the website is not intended for exposure to the general internet.
I had to upgrade from using the SQLOLEDB provider to the SQLNCLI10 provider to cater for the new datatypes in SQL Server 2008. It worked on my PC, but broke in production. What I didn't realise is that it worked because the SQLOLEDB provider is part of the Windows OS (MDAC/WDAC) so already exists on the client's PC. The SQLNCLI10 provider is included as part of SQL Server 2008 and has to be installed separately on the client machine (because most of them won't have SQL Server installed, but I do).
I can provide a link for them to download a standalone Microsoft SQL Server 2008 Native Client provider from, but how do I check if they already have it installed?
I have an app that I've built with VS 2008 Pro, which I believe uses version 3.5 of the .Net Framework. I want to run this app on an older machine to test the layout with some older browsers. The site is simple static site. This older machine doesn't have version 3.5 of the framework installed.
If I install just the 3.5 Framework on this older machine, can I then run the site in the browser without having VS2008 or VWD 2008 installed? I want to tweak the css in for the older browsers.
I have asp.net application with framework v3.5 compatibility.. How do i check that which framework is currently installed in client P.C. If client using old framework version, i want to acknow. him by a message box.....

I search on the internet and install MDAC,but not help. I am using Windows 7 with IIS7 how can i proceed.I cant be able to work on the project.
I have a web site that uses the both c# and vb.net in the app_code section. The different languages are separated into their own folder and correctly configured in the web.config.
<codeSubDirectories>
<add directoryName="BasicCode"/>
<add directoryName="CSharpCode"/>
</codeSubDirectories>
This works fine 95% of the time. In production using 2 load balanced servers I sporadically receive an error message along the lines of:
"Unable to find assembly
'App_SubCode_BasicCode.xxx,
Version=0.0.0.0, Culture=netural,
PublicKeyToken=null'.
The site is hosted in IIS7 and I think it has something to do with the name of the dll assigned during dynamic compilation. I do not see this problem in a single server environment. Could this be because when the session is balanced to the second server the dynamic compiled dll name is different?

View 3 RepliesI am getting this error, without any further details, when attempting to debug my ASP.Net project in VS2010. There are other developers using the same tools and code who are not having this problem therefore I know the problem is not in the web.config file. I have found several suggestions when googling the issue and tried them all to no avail. I uninstalled and re-installed VS2010 along with the .Net 4 framework. I made sure Anonymous as well as Windows authentication is enabled in IIS. I uninstalled and reinstalled IIS. I am at a loss. I can attach to the process and debug the ASP.Net code that way, but what I really need to be working on is a Silverlight app that is called from the ASP.Net and the breakpoints don't work in Silverlight when I attach to the process manually.
