ASP.NET Secure QueryString (Encrypt/Decrypt)

From my experience in web development most developers keep the query string variables unsecured which will lead into lots of security risks.

I have created three functions that will cover the above issue and make sure all your query string variables are secured.Get Source Code

Thanks for posting that link as its somthing im currently working on.

I also found this article
on the subject very helpful and it also contains VB code to do the same kind of thing (though I am working in C#).

One problem I have at the moment, along these very lines, that I was hoping to get help on is:

I have a menu dymanicly generated from an XML file, formatted with an XSL then displayed as an inline list using the ASP.NET XML tool and CSS.

I want to be able to call my <%EncryptQueryString()%> from within the XSL for-each loop, that is used to populate the HTML list. So that the querystrings in my menu http links cant be seen with a mouseover or viewing the source or in the url bar....

Becuase the menu is generated dynamicly the encryptquerystring and its parameters need to be called and set dynamicly also ... within the XSL for-each loop seemed the neatest way of doing this though i am stuggling to find any resources on getting <%%> tagged script to work under XSL.

So many thanks in advance if anyone can help me on this Smile | :)

Hey,

Regarding your problem i think it can besolved by assigning the xml source of your control at runtime, so in the code behinde you generate the XML source with all the querystring encrypted and whatever, then you can assign this XML document to the XML /XSL .NET control and you will be ready to Go.
Please let me know if this makes sense to you.

Hi guys !
I am trying to search my database with some value enterd by the user in a textbox.The search result has to be displayed in a ListBox on click of search button.

The problem is that when i use the LIKE predicate with 'A%' it gives all the values in ListBox but when i use LIKE predicate as LIKE '"+TextBox1.Text+"' the result is not shown and i get an error saying one or more Parameters are not given values.
PLease Please PLease Help me guys !

My code snippet is as follows:
void Search_Click(object Source, EventArgs e)
{
if (RadioButtonList1.SelectedIndex == 0)
{
// ....Intializing the Strings....//

tring connectionstring;
string queryString;

DataSet ds = new DataSet();
OleDbConnection dbconnection;
OleDbDataAdapter ad;
connectionstring = "Provider=Microsoft.Jet.OLeDb.4.0;DATA SOURCE=" +
Server.MapPath("\\Database\\New_Tool.mdb") ;
queryString = "SELECT Company_Name FROM CompanyName WHERE Company_Name LIKE '"TextBox1.Text"' ";

dbconnection = new OleDbConnection(connectionstring);
dbconnection.Open();
ad = new OleDbDataAdapter(queryString, dbconnection);

ad.Fill(ds,"Company_Name");

ListBox1.DataSource = ds;
ListBox1.DataTextField = "Company_Name";
ListBox1.DataValueField = "Company_Name";
ListBox1.DataBind();

}

The problem is in this line. In order for this to work you need to actually concatenate the content of textBox1.text with the sql string, not literally put the text "TextBox1.Text" within the string.

queryString = "SELECT Company_Name FROM CompanyName WHERE Company_Name LIKE '" + TextBox1.Text + "' ";

However, that said you should really get in the habit of using Parameterised queries, which allows you to just put a placeholder in the string

queryString = "SELECT Company_Name FROM CompanyName WHERE Company_Name LIKE '@SearchString'";

and then use the Parameters collection on the Command.

Hai All,

How can we call a codebehind function on onblur event of a control in asp.net 1.1?The control may be a web server control,html control,html server control or a web user control.
Actually, we can call a script function on such an event.But, how to call a codebehind one?

Or else, how to call a codebehind function from a javascript function?
Any suggestions?? Please welcome...
