Web Forms :: How To Use Null Value In Query String

Mar 10, 2010

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?

Web Forms :: How To Web Form Is Adding /null/ To Query String

Jul 21, 2010

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.

Active Directory/LDAP :: LDAP Query To Check If An User Is In A Group Or Not. Creation Of A Portal | Query = Null

Jul 7, 2010

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.

C# - Cannot Pass A Input From Text Box To A Query String And Then Keep The String In This Box?

May 28, 2010

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?

Null Value On .net DB Query

Jul 30, 2010

I'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?

ADO.NET :: Can Get A Value Or Null From An Entity Query

Mar 28, 2011

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.

Concatenating Results From SQL Query And NULL Columns?

May 11, 2010

I need to concatenate several columns of a table into a single value, then show that value in an asp dropdownlist. The SQL code I'm issuing is as follows:

SELECT UserID, CustomerNum, UserName + ' - ' + UserAddress + ',' + UserCity + ' ' + UserState AS UserInfo
FROM Users
WHERE (CustomerNum = @CustomerNum)
ORDER BY UserName

I then set 'UserInfo' as the text field in the dropdownlist.This generally works, except occasionally one of the columns in the database is null (for example, UserState). When that happens, the entire concatenation is null, and I get an empty entry in the dropdownlist.

Is there something in SQLServer that will allow me to ignore those NULL results, or will I have to code something up in the DataBind event?

SQL Server :: SELECT Query And Null Values?

Feb 3, 2011

I have stored procedure which selects records from an SQL table based on a bunch of user-input parameters.Just discovered that if a record in the table has null values in some of the columns (I haven't figured out which ones yet), then the SELECT is not returning the record (even if it satisfies all the parameters).The SELECT statement is supposed to allow for nulls, and I've been over it a bunch of times and am not sure what I'm doing wrong.Or do I need to get rid of all the null values in the SQL table, and prevent new ones from being introduced?

How To Test A Lamda Expression Variabe Query Result Is Null?.

Mar 13, 2011

var query = from emp in dbEmp.Employees join dept in dbEmp.Departments on emp.DeptID equals dept.DeptID where dept.DepartmentName.Contains(this.TextBox1.Text) select new { EmpID = emp.EmpID, EmpName = emp.EmpName, Age = emp.Age, Address = emp.Address, DeptName
= dept.DepartmentName };

if (query==null) Label1.Text = "no results match your search";

GridView1.DataSource = query; GridView1.DataBind();

Everything works in the right way, but the label doesn't show the message when query result returns null. The label can show without condition(querry==null). So how to test if a var query result returns nothing?

Forms Data Controls :: Setting The Selectedvalue Where The Result Of The Query Is Null?

Aug 20, 2010

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.
