I'm using webservice to integrate asp.net app with PeopleSoft. Sometimes, the value that I get from a querystring (eg in url below, request id =7) and pass it to PeopleSoft via webservice is blank, although the querystring contains key value pair. This causes the webservice integration piece to fail. What can cause this issue where the querystring value is blank? and how can I fix it?

I am using IIS 7 and have URL rewrite turned on for a friendly URL.
The problem is that in side that pages repeater (right under the captcha) when I click on the images in there the page redirects to /null/ which then throws a 404 error. I have turned off url rewrite and removed all rules and that didnt solve the problem so I dont think its related to that.
I have also noticed that in my master page if I use <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
then the client side ajax fails to load, sys becomes undefined and that may be the problem here
I'm at a loss, this is the first time I have seen these problems occur.

I'm working on a portal, and I need to check users conection on the ldap.
And if users are members of a special group then it works.
I've exactly used this link to make it works : http://msdn.microsoft.com/en-us/library/ff649227.aspx (almost work)
My point is : my ldap path seems good, no error anymore, when I log with my username and password.But when I querry it, it returns null, but I'm sure my user is in the group :
// Bind to the native AdsObject to force authentication. Object obj = entry.NativeObject; DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(SAMAccountName=" + username + ")"; search.PropertiesToLoad.Add("cn"); SearchResult result = search.FindOne(); if(null == result) { return false; }
I'm a normal user, i test with my account. I'm a member of the group that I'm looking for.

I added the iis tag because I am guessing it also depends on what server technology you use?
here is my code for selectiong some records from db table
string strSql = "select * from mtblNBD where SentTo=@SentTo and InternalStatus Is NULL order by DeadLine desc";
SqlCommand com = new SqlCommand(strSql, con);
com.Parameters.Add("@SentTo", SqlDbType.NVarChar, 50).Value = (string)Session["uname"];
here I am using parameters for SenTo field but not for NULL so it is ok... or should I use parameters for this field where value is NULL , if yes then how can I use parameter for this
I m facing some problem. i m not passing Dynamic string through query string..
I m using this code
string abc = "CPCB_" + TextBox1.Text + "_" + TextBox2.Text;
Response.Write("<script>window.open('xml.aspx?Flag=3&date='+abc,target='new');</script>");
I have a query that references many tables, however the main record doesnt necessarily have records in the other tables. In my formview itemtemplate, i bind the values of the query but I'm getting an obvious error when the value is null. This is what I'm trying to do: (the field is a boolean btw). These fields are hidden so I don't really care if it gets assigned a temp value or something.

Error: BC30452: Operator '=' is not defined for types 'Object' and 'System.DBNull'.
When using SqlDataReader.NextResult for 2 queries I am trying to I check if the second query returns any rows, but whether it has any rows or not the repeater2 is never hidden/false . I am doing something like this:

I have a simple ASP.net page:
<form id="form1" runat="server">
<p><asp:TextBox id="input_box" runat="server"></asp:TextBox>
<asp:Button Text="OK" runat="server" OnClick="run" /></p>
</form>
I want to send input from input_box to a query string, and then keep this input in the input_box when the page reloads.
That's the code behind page:
protected void Page_Load(object sender, EventArgs e)
{
input_box.Text = Request.QueryString["input"];
}
protected void run(object sender, EventArgs e)
{
string url = string.Format("?input={0}", input_box.Text);
Response.Redirect(Request.Url.AbsolutePath + url);
}
Problem is that when query string is not empty, string from input_box cannot be passed to query string. How to correct it?
We are sending an HTML encoded string in the Query string. It was working fine on IIS 6 (windows 2003). We have recently moved the website to Windows 2008 (IIS 7.x). Since the move any Query String that contains "+" sign i.e., "%2b" gives error on the server "404 -File or directory not found."
View 2 RepliesI've been working on building a back end on an access database that allows users to search records using a web search box. I've been able to successfully set up simple search query's but have run into trouble where multiple criteria with "AND" statements (OR statements would return too much to be useful). My problem is this, when all five text boxes are filled out the query returns records no problem, but if even one is left blank i get nothing what so ever. Is there any thing I can do in either SQL or VB to either ignore null values entirely or convert them to wildcard values?

I wanted to create a URL like http://localhost/menu.aspx/?id so that on typing this, it displays all the id's in the database. for eg:134
123
543
234
may be the id's which should be displayed after fetching from the database. However, it should be displayed as it it is without any control or without arranging in any gird etc. How can that be done?
Dim p = From i In context.persons
Order By i.fileNum
Select i.ID, i.fileNum, i.firstName, i.lastName, i.state, i.prPenPals.FirstOrDefault.startProfile, i.prPenPals.FirstOrDefault.endProfile
where for every person, prPenPal can have exactly one or zero records? I can do the above, but when I try to use p as the datasource of a ListView I get The cast to value type 'DateTime' failed because the materialized value is null. Either the result type's generic parameter or the query must use a nullable type.
I tried using
Select i.inmateID, i.fileNum, i.firstName, i.lastName, i.state, i.prLegals.FirstOrDefault.startProfile.ToString,
i.prLegals.FirstOrDefault.endProfile.ToString
but that didn't work. I got a blue squiggly line "Range variable name cannot match the name of a member of the 'Object' class" error I want the date if the record exists, and Null or Nothing if it dosen't.
I have drop dowm menu as follow.
<asp:ListItem Value="">none</asp:ListItem>
<asp:ListItem Value="STO">Stock</asp:ListItem>
<asp:ListItem Value="ORD">Order</asp:ListItem>
If I chose none, it stores data as "Null" If I Query the data as below, I don't get the data has value of "Null" SELECT tabale From type Where type <> STO or type <> ORD I get data that has empty string but not Null.
1, How do I write dropdown menu value in oder to get empty string instead of Null?
I did <asp:ListItem Value="">none</asp:ListItem> but this stores Null.
2, Why this Query won't pick up Null?
SELECT mytabale FROM type WHERE type <> STO or type <> ORD
