View 1 RepliesI'm just starting development on a new website and am trying to do it correctly, that is, with a DAL and not with queries in code which I had before. I understand the principles of it all, but I am finding this DAL with table adapters and wizards that do too much to be really messy to work with. Does anyone have any recommendations on what I should be using instead and a link to a tutorial on how to get going quickly with it?

View 5 RepliesI have an asp.net3.5 app. It has multiple client folders in the root folder. There are multiple web.config files. One is in root folder and one each in client folder. The web.config in client folder contains connection string for the database to be connected. I am using FORMS authentication. Each client has a specific page which are lying in root folder. This page redirects to the client specific folder and user logs in the application using the one more login page which is in client folder. And this page uses the connection string which in this client specific folder web.config.Now my problem is that I am not able to connect to the database using the client specific web.config on my live server. Live server is a Windows 2008 Datacenter and IIS7 machine. And my local system is XP IIS6 machine.Please help me to resolve this issue. Or how can I configure my application on IIS 7 &Win2008 DC system in WINDOWS authentication mode?

Ive integrated a custom asp.net web application into a Sharepoint site by creating a virual directory, that contains my web app files, that points to a directory in the Sharepoint inetpub folder.
On my local dev server I can access all my web app pages just fine by typing in /virtualdirectoryname/page.aspx
My Problem is that: When I deploy to my Live Test server that is internet facing, none of the pages that make a MS-Access database call will work.
The Error I receive is '[SecurityException: Request for the permission of type 'System.Data.Odbc.OdbcPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.]'
I have researched the issue online and tried numerous solutions which include giving all the assemblies in my application a strong name, and modifying the security policy to trust this strong name.
My Custom Web App consists of 2 projects
1. A Class Library Project (Data Layer)
2. A Web Application Project (Web Layer)
My .mdb database file is stored at root level within the Virtual Directory.
I have 1 class in the Data Layer (ClassConnect.cs) that when instantiated, creates the ODBC connection for all other pages to use (OdbcConnection dbConn = new OdbcConnection();)
I have a Connection String stored in the web.config file that is as such. When I deploy to the Live Test Server I change the path in this connection string, because I haven't figured out yet how to get a relative path that works.
I also place the dll's for my 2 projects in the Sharepoint bin folder.
Could anyone suggest what might be the dfference between my Local Dev Server and the Live Test Server and why I might be getting these errors.
what code should i write in web.config for the connection string for DB connectivity woth ado.net component??
View 2 RepliesI have added a web reference using the wsdl file that was provided to me. I also created an instance from the proxy class as follows :
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

But after this am totally confused on the next steps and how to pass username and password and test the service connectivity.I have attached the autogenerated code.
1) I notice that the module gets it's data in chunks. This is problematic for me because I'm using a regex to find and replace. If I get a partial match in one chunk and the rest of the match in the second, it will not work. Is there any way to get the entire response before I do my thing to it? I have seen code where it appends data to a string builder until it uses a matches on an "" end tag but my code must work for more that just (xml, custom tags, etc). I don't know how to detect the End Of Stream or if that is even possible.

I have been developing a quiz application in asp.net mvc. In this quiz user is give a list of topic to take quiz. On click of one of the topic the user is taken to new page. In the get part action of this page i have taken some parameters, generated questions for the quiz, register quiz for the user (save in db)and save the generated questions in db.
Now the problem is:
User see the page, if user hits the "submit" button after selecting the answer than it is ok but If user refresh the page. Then the get action is called again and new set of questions are generated and new quiz is registered to user.
How can i avoid this?
Is there any way to detect that the get action is called the second time or to detect page refresh in as.net mvc.
If you could suggest design changes that it is ok too? i just need to make sure if user refresh the page the question need not be generated again and new quiz should not be registered to user.
I have a sitemappath that I want to surpress on the home page of a website. Assuming the homepage is "www.mysite.com/default.aspx", what is the best way to detect when the base URL is being displayed?
IOW: I can do something like:
if request.servervariables("url") = "/default.aspx" then
sitemappath1.visible=false
end if
but how do I detect when the default url is being used, like:
www.mysite.com
without a page url at the end?
I tried to install MVC2 RC AspNetMVC2_RC_VS2008.exe [URL]? aiming it to use from VS2008SP1(Windows XP Pro SP3) but initially I got an error: Component Microsoft ASP.NET MVC 2 has failed to install with the following error message: "A different version of ASP.NET MVC 2 is already installed on your system. Please uninstall this version before proceeding with this install." The following components were not installed:
- Microsoft ASP.NET MVC 2 - Visual Studio 2008 Tools The following components failed to install:
- Microsoft ASP.NET MVC 2
By my distraction in "Add/Remove Programs" I deleted the entry "Microsoft ASP.NET MVC 2" instead of
"Microsoft ASP.NET MVC 2 - Visual Studio 2008 Tools" (told me by error text) and then succesfully installed
AspNetMVC2_RC_VS2008.exe Now I see entries in "Add/Remove Programs":
- Microsoft ASP.NET MVC 2
- Microsoft ASP.NET MVC 2 - Visual Studio 2008 Tools
- Microsoft ASP.NET MVC 2 - Visual Studio 2010 Tools
Well, it was the same before uninstall/install. I know that only MVC2 Preview can be used with VS 2010 and I gues that I uninstalled MVC2 Beta that was installed before for VS2008. Now I am in doubt: Had I installed MVC2 RC or what do I have with VS2008? How can I determine/check which release of MVC2 is installed with Visual Studio 2008 SP1 (or VS2010 Pro Beta 2)?

View 4 Replieswe have a situation where we log visits and visitors on page hits and bots are clogging up our database. We can't use captcha or other techniques like that because this is before we even ask for human input, basically we are logging page hits and we would like to only log page hits by humans.
Is there a list of known bot IP out there? Does checking known bot user-agents work?

View 1 RepliesWhat would be the best way to detect if the SessionState has died in order to send the user to a "Session Expired" page? I've successfully configured the app (in Web.config) to do this when the authentication cookie is gone (there's a setting for that), but so far I haven't found an effective way to do something similar when the SessionState is gone. The app in question holds some data in the Session, and should present the user with a "Session Expired - login again" page if any of them is gone.
So far, the only option I can think of doing it in each of the places I access Session, but this is obviously a less than optimal solution.
