Verifing Valid QueryString Against DB?
Nov 5, 2010
The pages on my site are generated based off data in a SQL 2008 DB, the data pulled is based off a querystring. Right now I fill a variable with the querystring info and then pull all the gamenames from the DB into a datatable. Once that is done I stepthough the entire table compairing thegame name to the querystring. If a valid entry is found I run a sub that does what I need it to do. This seams like a very slopy way of doing it. suggest a better, smother, more efficant way to veryify the querystring

What is the best way to test if a url & querystring is valid? For example, after a login redirect I want to make sure the target url is valid. If not, go to a default page.
We seem to have a problem with the querystring, starting with "ReturnUrl=", being duplicated and that throws an exception. We'd rather have it go to a default page.

The following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.

I'm intermittently seeing this exception being thrown:
A potentially dangerous Request.QueryString value detected
However when I look in the IIS logs I can see that the request that failed has no querystring logged against it.
How could this be? Are "dangerous" query strings being stripped from the log or something?

At the moment I'm trying to keep a certain site (asp.net) alive long enough for its replacement to be build in php. However I don't know much about .net or asp.net.
We are getting this error:

I'm encrypting the web.config in our web sites using aspnet_regiis. However, I want the ability to export the encryption key so if we need to move from Machine A to Machine B, asp.net will be able to decrypt it. When I run aspnetregiis -px "NetFrameworkConfigurationKey" c:keys.xml -pri, I get the following : 'Key not valid for use in specified state'. I've seen all kinds of responses online but they don't seem to apply. It's not an invalid key because when I use aspnet_regiis to encrypt sections of the web.config, they encrypt fine.

I am developing an application using ASP.NET (C#) and SQLServer 2008. In my database i have a field DepositDate and datatype is "DATE". On my data entry form i am taking dates using jquery datepicker and its returning date in textbox as dd/mm/yyyy format as per user requirement whereas i noticed in database its keeping date values as yyyy-mm-dd..i am confused.
While saving record i am getting not a valid date time as the only available conversion format is Convert.ToDateTime and my data requirement is DATE only. Can anyone suggest solution how to deal with it.?
here is the code
DateTime thedate = DateTime.Parse(txt_IDate.Text);
DateTime mdate = DateTime.Parse(txt_Mdate.Text);
db.AddInParameter(cmd, "@SIssueDate", System.Data.DbType.Date);
db.SetParameterValue(cmd, "@SIssueDate", thedate.ToShortDateString());
db.AddInParameter(cmd, "@SMaturityDate", System.Data.DbType.DateTime);
db.SetParameterValue(cmd, "@SMaturityDate", mdate.ToShortDateString());

A long running background process creates a text file to indicate the completion of the process. From the frontend, I'd need to check every few seconds if the text file has been created or not.
I am doing this check from http://DomainA.com However the file is created in http://DomainB.com/Mytext.txt
write a jquery script that checks for a file across domain?
PS: Currently, I am doing a ajax postback that executes a WebMethod in ASP.NET that creates HttpWebRequest. This works functionally, but I have major performance problems. So, I need a light weight way of finding if a URL is valid or not.

I have an access database with membership and roles. All works fine on my local computer. When I then load onto the internet, the login works OK for about a day and then I get the error
System.Exception: AccessFile is not valid: E:hshome...........
The web provider has reloaded the MDAC drivers so that doesn't seem to be the problem.The database was built around the info from this website. http://imar.spaanjaars.com/404/using-the-microsoft-access-providers-to-replace-the-built-in-sql-server-providers
I'm unsure why it works for a day or so then this error arrises ? why this error appears and disallows login / connection to the database ?

I'm putting some name/value entries into a GlobalResource file and am getting the error:
The resource name '01' is not a valid identifier
why '01' is an invalid name? Of course I will change the name to get around this for now, but am curious as to why the warning appears (in VS2010).

I imagine this would be simple, but I can't find an answer. We set the theme of a page based on a query string parameter (like '?theme=theme1' etc). I just want to know if there is an easy way to tell the theme name is valid, before setting it, or catching and handling the error if it is invalid. The error I get if the theme does not exists is:
"Theme 'theme1' cannot be found in the application or global theme directories."
I am not sure when the exception is thrown. All I can think of is searching the folder, but I would think there would be a simpler way.

I have developed an application using xmlrpc webservice and i have got some error like 'Response from server does not contain valid XML'. I have written xmlrpcstruct in the interface class and make this interface derived from xmlrpcproxy interface. In the main(), i have written the definition of the interface with xmlprcProxyGen and called the xmlprcstruct and passed the parameters to the webservice. When I am running the project, I got the error on the code for passing the parameters to the webservice point. What I am missing here?

I've written a View (form) that has a section with two radio buttons and a blank <DIV> block that will dynamically be updated. When one radio button is clicked, a <DIV> on the page is updated with fields specific to that radio button option. When the other radio button is clicked, the <DIV> on the page is updated with fields specific to that radio button option. To determine what content gets displayed when a radio option is selected, I call a JavaScript function and set the content appropriately using jQuery. Pretty easy so far. Let's assume that the User has toggled the radio buttons and filled in some data. Further down in the form, the User has entered an invalid e-mail address. When the User submits the View, the ModelState is invalid. If it is invalid, I return the View.
[Code]....
Problem is, when the View is returned, some of the form fields (that are static) are in place. However, the <DIV> that was previously updated based on User radio button selections is reset to its original state. When we return a View because of an invalid Model State, is MVC smart enough to return the View in it's modified state (in this case, with the modified DIV and dynamically added content)?
