Just for curiosity, i want to know i how many ways we can write the parameters in a querystring. I have encountered the following
& (is common that we use in our most of the application)
, (in some banking application)
; (bank.co.in/BANKAWAYTRAN;jsessionid, this is from my banks QS :-) )
I'm at the end of a project and have hit a wall. I'm pretty unfamiliar with VB so this is why I've left this piece of the project for last.
I have a popup window in which I pass some values via QueryString. I want to be able to pull them into my application and do some math on them and then write them out to my aspx page. The problem is I don't know where/how to begin. I've searched around the asp.net boards, but can't seem to find any good starting point.
I'm reading in some dollar amounts, a percentage and an Id that I'll use to pull a payment schedule (number of payments). I'm trying to get at a payment breakdown. I was thinking of writing it Something like this:
[Code]....
I am write code in java script
window.location=document.location.path
when I am search college then display url
http://localhost:1682/FinalTest/searchcollege.aspx?CollegeId=25
if I am overwrite url in Addressbar
after My url ---
http://localhost:1682/FinalTest/searchcollege.aspx?CollegeId=25&id=3&cid=5
I want when I am search any another college then show my url
http://localhost:1682/FinalTest/searchcollege.aspx?CollegeId=20&id=3&cid=5 means only change my CollegeId=25 to 20 and other parameter is not change. Use only javascript.
I've got a formview that does a simple 'SubTotal' calculation based on some checkbox inputs. I write out the subtotal to an asp:label control. I want to be able to also be able to write that value into the QueryString so I can carry it over to another page. I can't seem to access the label from my codebehind (intellisense doesn't find it). I assume I'm not making the correct reference to the formview label control, but I don't know how to go about getting at it.

How can i use querystring for this-
Here in below code i have used querystring for sending imagename from this page to another page. Now i just want that with this imagename in also want to send span element's text with same querystring.How can i achieve this?
[Code]....
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 am using asp.net web application and right now I have like 3000 members on the site. My question is, what other means out there that I can program or query to see how the users on the site uses the system and how frequent they log back in or come back?
View 7 RepliesWhat are the available ways to pass a parameter to a UserControl ?I know the session option but actually I don't prefer it because it'll retain when any exception is occurred. I mean I prefer something like the QueryString (rely on the call or request).Note: My UserControl will be shown throught a modal popup using JQuery.
View 1 RepliesWhat are the ways to detect a computer other than ip address. I saw some bux website where they do not store ip addresses but detects computers. How this is possible? Do this a program, or any other? Is this in anyway related to cookies, or mayby something else? A web application automatically detects computers using something other than an IP address. What could it be?

View 1 RepliesI want to know what are various ways to consume a WCF service keeping in mind the value for InstanceContextMode? If I create a proxy object and consume it within using block, I am explicitly forcing system to create a new object each time. What are other approaches? Which one is the best approach? I have heard using block is not a great option.
View 1 RepliesI have been looking at ways of encrypting querystrings and I have found a few good examples.. but, I just want some clarification on what is most often referred to as the EncryptionKey and the characters that are in that key....Is there basically an unlimited number of alphanumeric combinations that could be used in the following code as the encryption key, is there anything that someone should be CAREFUL about including in that key?
using System.Security.Cryptography;
private static string EncryptionKey = "!#$a54?3";
/// other examples: "r0b1nr0y"
///in a try-catch:
key = System.Text.Encoding.UTF8.GetBytes(EncryptionKey.Substring(0, 8));
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
inputByteArray = Convert.FromBase64String(Input);

View 2 Repliesi know that i can set a Label's text by using this syntax:
lblMessage.Text = (string)GetGlobalResourceObject("resxFile", "message");
but what's the difference(benefit/drawbacks) to using this syntax:
lblMessage.Text = Resources.resxFile.message;
also, i just found out that this second method doesn't work for local resource files. is there a different syntax used for local resource files?
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?
My new office project is based on an MVP design and is in VB.NET (.NET 3.5), using multiple libraries (like EntLib, internal corporate framework, etc.). The number of DLLs used as references is so huge (almost 50) that when I try to build/debug the application in VS2008, it takes almost 3-4 minutes to get the website running successfully.Wanted to know if there are any settings/areas which upon some modifications can help me reduce the build time? and what exactly can be the major reasons behind this long loading duration?

View 6 RepliesI'm trying to show a demo of a Web site in progress in two ways, and having two different problems:
1. I created a test domain on GoDaddy. Tried to deploy there, but I need IIS 6 on it. Having trouble finding it. I started a web host on Aspspider.net, which has ASP.NET loaded on it. I have to wait until I can create a site. 2. I hoped to pass the deployment package to the client to load it onto his local machine. However, he got the following errors running the deploy.cmd file:
"Error: The metabase key '/lm/w3svc' could not be found.
Error: The metabase Admin Base Object could not be instantiated. Perhaps the 'ISS 6 Metabase Compatibility' feature is not installed.
Error: Class not registered"
Is there anything I can do about #2, or should I wait for #1 and hope I can deploy to the site when it's created?
I currently have a function that gets some data from the database and puts it into a dataset. The return type on my function is GenericCollection (Of CustomerDetails)
If I do this:
Dim dataset As DataSet = Read(strSQL.ToString) 'Gets Data from DB
What's the most efficient way to map the dataset results to an collection of objects. More importantly, since I'm using GenericCollection, is there a way to do this in which I can call a function from the ObjectType class (CustomerDetails) that would have a means to converting that specific object.
Or is there a way in which I can use a function that would handle all types?
Is there a way to do something like:
Return returnedResults.TransformDataSet(dataset)
In which returnedResults is an object collection Of CustomerDetails, or would it simply be easier to have TransformDataSet return an object collection Of CustomerDetails by itself?

A popular example for various methods of using the animation extender is not working for me. In the example there are 4 methods detailed for invoking an animation:Markup (this works)Selectively playing the Animation Already defined in Markup for an AnimationExtender on the Page.

I have been working on web services for quite sometime.Have been creating and consuming simple to intermediate levels of web services.But now i want to start using some third party web services.I have got to know that there are good ways to troubleshoot issues in our own web services or any third party web services. For example, if a particular web method was working since 3 months and all of a sudden, it stopped working as expected or its not giving the results now. In these kind of situations, what are the best approaches to troubleshoot the issue.Can someone please share some points on this? May be some right articles having some examples will give me the clear picture.
View 2 RepliesI have a button in a Gridview that updates selections. This works fine.
I made a DropDownlist wich should put the variables "Kursistnummer" and "pcsvar" in a new table.
The button in the Gridview writes the value of "kursistnummer" and the text "pcsvar" in the new table.
But if i call the sub"btnTilmeldPc_Click" i get this error:
Procedure 'LP_KursistEksamenPc' expects parameter '@kursistnummer', which was not supplied Its friday and its a bit hard stuf for me.
I have these procedures:
[Code]....
and stores procedures in my db

and a general dropdownlist

and my Grivwiev

Suppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?
