i query a database for retreiving all the columns. I will probably have many rows. Im trying to output the query results into an html table. This is what i have so far:
[code]....
How could i store the many rows and output them using html as soon as i open a page?
[Code]....
Well I'm not familiar with SP's yet, and I can't find a single example of what I want to do. basically I want to retrieve the town & county where the customers id are equal (note there will only ever be 1 result)
I can't figure out how to address the results to be stored within the output variables.
I am converting an old script from ASP to ASP.NET and would like some advice. The original ASP script used Response.Write to output information about what happened during execution. I have rewritten the entire thing in ASP.NET but it is new to me as an old-school C programmer. The job requirements include using the VB flavor of ASP.NET, btw.
I originally put up a TextBox and edited the text property to dump my final report. Now they want different colors for different message importance and I find that the TextBox can only do one color for all lines. I fell back to the old standby R.W but I get a message that it's not declared and from looking around I see that it's an issue because I'm calling it from the code behind and that is 'out of scope' from the HTML elements of the page itself.
My question is what is the best way to output information to the web page with different lines being different colors from a page's code-behind? Secondary question - if I have misunderstood anything feel free to correct my thinking. :)

View 2 RepliesTrying to output the PageName in a masterpage.
Masterpage has a Literal in which I am setting by accessing a property on the MasterPage "PageTitle".
<head runat="server">
<title><asp:Literal ID="litTitle" runat="server"/></title>
<asp:ContentPlaceHolder ID="head" runat="server" />
</head>
The child page is like this:
<asp:Content runat="server" ContentPlaceHolderID="content">
<%
MasterPage master = Master as MasterPage;
master.PageName = "Log in";
%>
</asp:Content>
And the property PageName is coded thusly:
private string _pageName;
public string PageName
{
get
{
return _pageName;
}
set
{
_pageName = value;
litTitle.Text = _pageName;
}
}
I'm guessing this is because the page output has already been rendered, but as I say I don't know enough about ASP.NET. I guess I'm after something similar to PHPs ob_start().
I have an ASP.NET website in which I have to perform a certain operation. I have to displaying the ID's from the DB on menu.aspx page in this format {1:2:3:4}. The above format is not a problem and can be just be written with

Note that I am saying that user will type this URL. I know that query string can pass the values from one form to another but this is a single web form and if I attach this ?search=yes, it should return the result. How can this be done?
I plan to use output cache for my page and also specify sql dependencyi succeded in doing it the following way
[Code]....
Suppose if i want to implement a dependency on the sql query , i create an sqlcache dependency object and specify the sql command to it.Set the notifications .But how do i add this sqldependency to the output cache?For example: if i need to add a file dependency, i give something like Response.AddFileDependency ("filepath"); is there any similiar command available for sqldependency as well? I'm confused about this because, most of the examples i've looked into, does a cache.insert , which defeats my purpose as it's object caching and not output caching. In a nutshell, is it possible to attach a sqlcachedependency to o/p cache inside the controller action
datacontextclass dc=new datacontextclass ();
var news= dc.GetNewsCompany(Int64.Parse ( _idCompany));
if (news.GetEnumerator().MoveNext())
{
foreach (var item in news)
{
drpListNews.Items.Add(item.Title);
}
}
return error:{"The query results cannot be enumerated more than once."}
how can check result != null in LINQ;

I was wondering if there was an easy way to change the output generation properties of the HTML editor.
I need to change it from the current XHTML standard (spans, etc) to legacy styles; <b>, <u>, <i>, etc.
The SQL is below - each result is coming up 3 times rather than just once.
SELECT Consignments.LegacyID, TripDate, CollectionName, DeliveryName, Pallets, Weight, BaseRate, Consignments.FuelSurcharge, AdditionalCharges, BaseRate * Quantity AS 'InvoiceValue', Consignments.Customer, InvoiceNumber,
CASE
WHEN child.LegacyID = Consignments.Customer THEN child.LegacyID
WHEN parent.LegacyID = Consignments.Customer THEN parent.LegacyID
ELSE this.LegacyID
END AS 'InvoiceAcc'
FROM SageAccount this
LEFT JOIN SageAccount parent on parent.LegacyID = this.InvoiceAccount
LEFT JOIN SageAccount child on this.LegacyID = child.InvoiceAccount
JOIN Consignments on (Consignments.Customer = this.LegacyID AND this.Customer = 'True')
OR (Consignments.Customer = parent.LegacyID AND parent.Customer = 'True')
OR (Consignments.Customer = child.LegacyID AND child.Customer = 'True')
WHERE (this.LegacyID = @Customer) AND (TripDate BETWEEN @fromdate AND @todate) AND (InvoiceNumber IS NOT NULL)
The SQL was given to me for another similar query, but this time I have modified it to try to use it for the query I'm doing now, so I'm assuming that I'm doing something stupid.
I have a query using LINQ-to-SQL. It queries an underlying database table Rooms. It uses Where conditions to narrow down the results, namely:
Gender.
Current Occupancy < Max Occupancy
Available Flag is Checked
I know this should return results but it keeps returning an empty set. Any ideas? Code is below
Dim selectedHalls = (From sh In dbHalls.Rooms _
Where sh.gender = Session("gender").ToString _
Where sh.max_occupancy > sh.current_occupancy _
Where sh.is_available = 1 _
Select sh.building_name).Distinct()
UPDATE: I've verified that the issue is with the statement where sh.is_available = 1, which doesn't make sense since this is a bit field.
I've managed to use my MS Access database with repeaters and gridviews in my website. Basically, printing the result of a query directly to the website seems easy enough using something like this :
[Code]....
After quite a bit of googling this seems to be a common way to do this. My question then seems kinda silly.
I want to use some of the data from the query in for example a variable without sending the data to a repeater or gridview and so on. Say I just want the username and a password from a database and want to store the username in one variable and the password in another for further use in the code. What do I do?
I can't seem to change the order of the results coming back from a linq to sql query, I want just to return the distinct values from the field x.manufacturer in alphabetical order, this is what I have and it isn't working:
public IQueryable<string> Dropone()
{
return (from x in CAT.CatalogueDatas
where x.Parent == null
orderby x.Manufacturer
select x.Manufacturer).Distinct();
}
Currently I get the distinct values in non-alphabetical order, in fact I'm not sure what order they're coming out in, don't think it's the order in which they appear though.
I have an asp.net intranet site hosted on IIS on my computer.
On one page you can enter two user id's and get a side by side comparison of their roles in our (custom app) system.
I often use it to add roles when I'm setting up new users. After running the query, if i change a role and run the query again it will not show updated results. It's being cached somehow. I have to go to another page and come back and them run the query to get updated results.
How can avoid having to navigate away to get the updated query results displayed.n

I have a Query which I run as an SQL. This is my SQL:
"SELECT COUNT(*) As NoDup FROM [XXX Dir] WHERE (FileName Like 'XXX_YYY_20100916.txt')"
The "XXX Dir" is a table and "FileName" is a text field within that table.
When I execute the SQL in the Query development windows, it returns a single value like 2.
I would like to assign that value to a variable so I can use it in my VB code.
Is there a tutorial on a way to query an excel and have the output displayed for the user?

However, if there are no results returned this will return an error. Is there a way for me to tell it to act as if the date is older than six months if there is no value at all? e.g., could I in pseudo do something like:

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?
I'm using Visual Web Developer 2010 Express. This is my first attempt at creating a .NET page. I have a Gridview on a page that displays the results of a GridQuery. This works.

How do I check the state of the check box so it will run the query with or without the "filter".
