Populate Label From Single Field In Sql Server?
Sep 15, 2010
I have a column in a table that contains a message and I want this message to be displayed in a label. Here is my code which currently doesn't populate the label.
Protected conString As String = ConfigurationManager.AppSettings("sqldirectory")
Dim cnn As New SqlConnection(conString)
Dim cmd As New SqlCommand("select message from [database].[dbo].[table]")
Dim dr As SqlDataReader
Try
cnn.Open()
dr = cmd.ExecuteReader()
lblMsg.Text = dr(0).ToString
Catch ex As Exception
dr = Nothing
Finally
cnn.Close()
End Try

I have an email contact form that I have successfully populated the account users Username and email address into text boxes
I also use a text box and session variables to send parameters to a stored procedure and return a single row result in a form view.
The thing I am having an incredibly hard time figuring out is how to populate a single textbox with the data from any of those fields. or the whole control as a single summary.
Just for starters I am actually an IT Manager and NOT a coder so this is entirely a hack job if there ever was one...
here is my aspx code
<%@ Page Language="C#" AutoEventWireup="true" MasterPageFile="~/RMSWeb.master" CodeFile="Service2.aspx.cs" Inherits="_Default" %>

I was thinking about the fastest way to retrieve a "set" of objects related to a specific user. For instance, if I was to create a website similar to Flickr where people upload lots and lots of photos(jpegs) what would be the fastest way to be able to retrieve those photos from the SQL Server database. Scenario 1: You store metadata about each file they upload to the website as a single row in a database table. Then when you want to retrieve a specific users uploaded files you simply scan the database file for every row matching the UserID and store them in memory.
SELECT PictureId, UserId, PathToFile, Caption, (etc.)
FROM Photos
WHERE UserId=@UserId
This, of course, gets all the information about all the photos a single user has uploaded. My concern with this approach is when the user activity goes from a few thousand to being in excess of a million.
This approach seems fine for a small website but does this method work for a million plus user website like Flicker or MySpace? When you have a million users and millions more photos does this approach still perform at acceptable speeds?
create a collection in memory of "ALL" the PictureIds' for a single user and store them in-memory, in a collection and then save this collection as a single VARBINARY(MAX) field in the SQL Server Database. So instead of having to find multiple records in the Photos database you would simply need to find one, which would include all the PhotoIds' that belong to the user. In essence, translating into the phrase, "If you find one, you have found them all". And improving server performance by leaps and bounds. I only have about a year experience in working with SQL Server and ASP.NET so Im not sure if this solution is practical, if its already been tried, if it can be done.

I am trying to populate the values of multiple rows in single row in gridview using c sharp in rowdatabound section of code behind page like:
Col1 Col6

I have changed this to
Col1 Col6
a 1

What wrong with the code below?
if (e.Row.Cells[0].Text == "" && e.Row.Cells[5].Text != "")
{
for (int a = 0; a<GridView1.Rows.Count; a++)
{
string s = GridView1.Rows[a].Cells[5].Text;
GridView1.Rows[e.Row.RowIndex - 1].Cells[5].Text += s;
}
}
What mistake I am making?
Cell[0] is Col1
Cell[5] is Col6

This is the first time I have played with the web part of Visual Studio and I would like to know how to:
1) When A user selects a date from the calendar it will populate the grid with available classes. (I have already setup the query however I don't know how to execute it using the text from Label1).
See picture, "Label1" will show the date from the selected date on calendar, from there I want the label to populate the Grid with available classes.

I'm new to .net but I'm developing this website which needs some dynamic data inserting so I'm using asp.net 3.5 c#. I've got it working on my local machine but as soon as I upload to the server it no longer populates the label fields. I'm not getting any error messages, the rest of the page appears as normal. So I know this is like asking how long a piece of string is, but what is going wrong here, as I say it's working locally just silently failing on the server. I've tried just populating the label field with a hardcoded string and even that's not going through, it's almost as if the class can't see the label.

I've been trying to find a solution to my problem for about 2 days now, and have found nothing. I am new to .net and not really sure how to accomplish this. I have 4 tables in a database, Vendors, RepairCos, Cons, ConRepairHistory. What I'm trying to do is make a page called SendOutForRepair.aspx that has a insert item template where the first control is a dropdownlist that is attached to the Cons table (got this figured out) and is populated with the Serial Number field. I would like the selection from the dropdownlist to populate the 2nd control (VendorID) that is also from the Cons table.
example record from Cons Table: Serial number VendorID
508585 1
so when 508585 is selected in the dropdownlist, it would populate VendorID with 1 (this is my issue)once this happens, the user would fill in the other fields (hours, issue, repairco (also a dropdownlist linked to RepairCos table), RA Number, DCI, DPU, DRB, Cost, Record (which is a identity field and primary key for table) and when the insert link is pressed will insert all 11 fields as a new row in the ConsRepairHistory table. so the new record in the ConsRepairHistory table would look like:
Serial Number VendorID Hours Issue RepairCoID RA Number DCI DPU DRB Cost Record
508585 1 2250 alarming 2 20222 11/16/2010 11/17/2010 null null 3
the RA Number, DCI, DPU, DRB, Cost all allow null values.

I am working on a project where the customer has a large database of products, they want to select the product by the id number and I thought it best that the description also show up. What I have is a dropdownlist that is linked to the id number in the database table and that works just fine. My problem comes when populating the corresponding description from the table into either a textbox or label(doesn't matter which one I use) I can accomplish this without ajax just fine but we would like to reduce the postbacks to the server. I have never used ajax before Here is my code from the aspx file.

I'm going to try to explain this the best I can. I have a datalist that is displaying a large amount of data based off a CollectionID number. Within each set of data are CollectorID numbers. Now there can be several different CollectorID numbers tied to each CollectionID number. So therefore, the same data is being duplicated several times with the different CollectorID number. What I would like to do is concatenate all the CollectionID numbers into a string that are related to the CollectionID number and populate that into the corresponding label.
I've tried modifying the stored procedure to concatenate the CollectorID rows from the table they are located in but that seemed like a very large challenge.
My latest attempt involved removing the CollectorID from the original query. Then I wrote a datareader on the ItemDataBound event grabbing the CollectorIDs but it is missing the first CollectorID in each set.

I am having a hard time attempting to update a single field without having to retrieve the whole record prior to saving.
For example, in my web application I have an in place editor for the Name and Description fields of an object. Once you edit either field, it sends the new field (with the object's ID value) to the web server. What I want is the webserver to take that value and ID and only update the one field. There are only two ways google tells me to do this:
1) When I get the value I want to change, the value and the ID, retrieve the record from the database, update the field in the c# object, and then send it back to the server. I don't like this method because not only does it include a completely unnecessary database read call (which includes two tables due to the way my schema is).
2) Set UpdateCheck for all the fields (but the primary keys) to UpdateCheck.Never. This doesn't work for me (I think) due to my mapping layer between the Linq to Sql and my Entity/ViewModel layer. When I convert my entity into the linq to sql db object it seems to be updating those fields regardless of the UpdateCheck setting. This might be just because of integers, since not setting an int means it is a zero (and no, I can't use int? instead).

I have a SQL Server table with a number of fields that are defined with the "Float" data type. I'm running a simple query to retrieve the data from this table and use it to populate a Data Table in my C#.net application.
I just discovered that the data type of the Data Table fields is Double, not Float as I expected. As such, when I store a value like 0.157 it ends up getting stored like this: 0.15700000524520874
I'm aware that such extra "noise" occurs when such a conversion occurs. My major question has to do with why .Net didn't set the Data Type to Float (ie. Single) when the table was first populated?

I've got an ASP.NET 4 site on which I want to allow people to put '<' in their password. However, .NET gets in the way by blocking (what it sees as) an attempt to put HTML in a form field. I know I can turn off input validation entirely, but I only want to turn it off for this one field. Does anyone know an easy way to do that?

I'm currently learning more about C#.Net via video tutorials (I'm a visual/hands on learner) and I'm learning more about Console.WriteLine functions.
What I want to do is take this code (see below) wich is a bunch of console writelines and make it so that each time the button on my page is clicked the lable field is populated with a new random number.
I understand how to use the lable field with static data (Label1.Text="") but I just can't figure out how to get the method that I want to execute into that label upon a button click.
It is somewhat difficult to explain what I am trying to do. but, essentially I just want a lable saying "Random Number Function" then a button that says "Generate Random Number" and a non-labeled lable that will populate a random number upon clicking the button. With a little help, I can get this and then I'll be able to create all the rest of my console.writeline functions into my asp page for later reference :D
And I do appologize if this is in the wrong section. I am very green to this. I've only take a half semester of C#.Net and half of Java. My Asp.Net and Visual C#.Net are self taught. And, I often hit walls with using google for what I'm after, probably due to my lack of termonology knowledge.
