I'm very new to asp.net and c#, I have been thrown in the deep end with a project at work and I'm really struggling to overcome this problem so any help will be very greatly appreciated. I have a form with a number of textboxes that users use to update records in a database table with the use of a stored procedure. The problem is that I can't get the form to just update the boxes that a user has filled out. The form is working at the moment only if the user fills out all the boxes on the form which obviously is a waste of time if they only want to update one field. I have tested the stored procedure and it works fine. Please find the below code I'm trying to use!
Hello, My company Intranet has a form that agents can use to post their comments about the company to upper management, but our customer service department would like to modify the form so that the agent has to pick from a comment type. The dropdown options on the form will be as follows: ComplimentsComplaintsGeneral CommentsSuggestions Each dropdown option has a designated table in a SQL DB.Using postback on the same page, I need to change which fields of the form are visible based upon which dropdown selection the user chooses, and I need the fields to then be inserted into the table that corresponds with the dropdown selection item. For example: If the Compliments dropdown selection is picked, I need a text box to show for the user's location, the name of the customer, account number, and the message box. Once the submit button is clicked, the characters in these boxes need to be inserted into the Compliments table using its data adapter. However, if the user selects Suggestions, the name of the customer and the account number should not be visible, since these fields do not exist and when the submit button is pressed, the Suggestions table should be updated. If you need more information, I will provide whatever is needed. As always, thanks for everyone's assistance. Chris
I'm trying to create a online update form to a SQL table. I've neverdone this function before, and I'm not quite sure I have the codingcorrect. Below is the coding for the Update statement.final String udc = "UPDATE INTO " + "Comm_WebSubmission Set ProjectID= request.getParameter("ProjectID")(Assigned,DateAssigned,Status,StatusDescription,Re solution,CompletionDate)values(?,?,?,?,?,?)";Any help you can give me would be greatly appreciated.Cat
I have a Table which stores data from two different databases. To update it I made a Web Form that opens a single record where you can edit the data (using TextBox). Then there is an Update Button, which is supoused to Update that record in the SQL Database. However, for some reason it does not work. I get no error and every thing seems to work fine, but the data is not updated. When running the same UPDATE statment in the SQL Query Analyzer everything works just fine. Here is the code for the button click (For test purpose I've set a spesific record to update the Task cell to "Test" and I've adde a DataGrid to be able to see if something is happening): Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click Dim objConnection As SqlConnection Dim objDataAdapter As SqlDataAdapter Dim objDataSet As DataSet Dim objDataView As DataView Dim strConnect As String Dim strSQL As String Dim strUpdate As String strConnect = "Persist Security Info=False;Integrated Security=SSPI;server=SRV01;database=DB1" strSQL = "SELECT * FROM Users WHERE UserID ='" & Request.QueryString("UserID") & "'" strUpdate = "UPDATE Users SET Task = 'Test' WHERE UserID = 36" '" & Request.QueryString("UserID") & "'" objConnection = New SqlConnection(strConnect) objDataAdapter = New SqlDataAdapter(strSQL, objConnection) objDataAdapter.UpdateCommand = New SqlCommand(strUpdate) objDataSet = New DataSet objDataAdapter.Fill(objDataSet, "User") objDataView = New DataView(objDataSet.Tables("User")) dgrTest.DataSource = objDataView dgrTest.DataBind() objDataAdapter.ContinueUpdateOnError = True Try objDataAdapter.Update(objDataSet, "User") lblTest.Text = objDataAdapter.UpdateCommand.CommandText Catch ex As Exception lblTest.Text = "Error" End Try End Sub
Bear with me plase as I am nto very familiar with the coding world. The project I am working on is giving me troubles. I am trying to set up a form that can be used on line for our sales staff. It is a call activity form that I was hoping to submit to the DB I Have created in SQL. I would like the sales staff to fill out this form and then have their information transferred to the DB so that I can generate reports from that data. The trouble I am having is getting the intial connection to the DB opened up using the submit button on the form. I go into the code behind the page, and I have entered many scripts with no success. I continue to see that I receive erros when I try to use the opening line: Dim cn As New ADODB.Connection
If anyone out there has some sample scripting that would help me with this, I would really appreciate it. Thank you.
Question related to Visual Basic Video Lesson 09 (Databinding.wmv) by Bob Tabor.
Made a table and a UI form according to this lesson (table colums: CustomerID, FirstName, LastName).
Is it possible to use the same or an identical looking query form to find "Bob" by typing Bob in the Fist Name textbox or "Tabor" by typing Tabor in the Last Name textbox as in FileMaker?

I've a weird problem in my application. In of the pages, while trying to update the text box "Name", when I enter Linda's test, it gets saved as Linda''s test. I'm not sure if this is a problem due to SQL server. When I look at the stored procedure, I don't anything different. Also, when I update the table directly in SQL Server, the result is displayed in single quote. But if I update the field thro' the application, the returned name is with double quotes instead of single quote. Has any of you faced problems like this? What am I missing? What do I need to do to get the name saved the way I entered (with single quotes) instead of double quotes?
I need to update the AcquiredFrom table from source_office table. both the tables are from different database and server. we can match them on Code and source code. Initially if we can find out the discrepancies and then how can we fix them. Also there might be some dealerships that would have to be added to acquiredfrom table from the source_office table if they are not there already.
Table 1 (AcquiredFrom) database (Service) Server(FS3) Select Code, Name, ContactName, AddLine1, AddLine2, city, state, zip, PhoneNumber FROM [dbo].[AcquiredFrom] Order by Code Table 2 (source_office) database (DCP_PROD) Server (DPROSQL) Select source_code, name, addr1, addr2, city, state_id, zip, phone FROM [dbo].[source_office] order by source_code
Hi, I got a problem. I installed Microsoft SQL Server Management Studio Express 2005 version. And I created a Compact database. I created an connection in SSMSE to connect the database and opened a query form. then, i run the following sql:
Select * from Table1
It returned 3 records to me. After that, I used program to insert record into this table. Then i ran this sql again, it still show me 3 records. I closed the query form, and re-created a new query form, then run the sql, it returned 4 records to me.
Why? It's very strange and difficult to operate, right? Is there anyone know how to make the SSMSE to return whole records without any close query form and re-create query form operation?
Hi everyone, What is the main difference between first form normalizations and second form normalization ? In my opinion, they are both generated for the same operation which is to prevent redundancy(in other words; duplication of data in several records). So would you please explain it to me ?

Relevent code of mine is as below. <script runat="server"> void addtosalelist(Object sender, EventArgs e) { .... .... dbConnection.Open(); .... .... dbConnection.Close(); }
SELECT @topicList that produces a list of all the topic_names in the database seperated by commas. That's fine.
I couldn't follow all the code in this thread (http://www.sqlteam.com/Forums/topic.asp?TOPIC_ID=18363) but I was able to extract and modify this code:
DECLARE @topicList varchar(200)
SELECT MAB_topics.topic_name INTO #tmp FROM MAB_topics, MAB_articleIndex WHERE MAB_articleIndex.article_ID = 76 AND MAB_topics.topic_ID = MAB_articleIndex.topic_ID
SELECT * FROM #tmp
drop table #tmp which returns the two topic_names that I'd expect. (Note: this is my very first day declaring variables and using temp tables.) So I keep thinking that the following code would combine the two above working functions. But, when I run it in Query Analyzer, it just returns "(2 row(s) affected)" instead of a recordset.
DECLARE @topicList varchar(200)
SELECT MAB_topics.topic_name INTO #tmp FROM MAB_topics, MAB_articleIndex WHERE MAB_articleIndex.article_ID = 76 AND MAB_topics.topic_ID = MAB_articleIndex.topic_ID
drop table #tmp What am I doing wrong? I'm sure it's something simple but I've been reading and trying and reading and trying for a few hours and haven't gotten it yet. The ideal response would figure out what I'm trying to do as well as what my mistake is and explain how I'm misthinking. A close second would be just fixing my code. :)
HiI am using Visual Web Developer 2005 Express and SQL Server Express 2005.From Northwind I can display data to Gridview.Could someone point me in the right direction on two points.How do I start a new database (.mdf) - I cannot find this option.I can change Northwind around - but I want to start my own database. Once I have that sorted - how can I "insert" data into database using a dropdown box?A "dropdown" box such as you would find online. Thanks in advance.Stephen
I need to make a query to a SQLserver db passing values from a dropdownlist and two text boxes as my criteria. Now if nothing is selected and the button is pressed, I would like to return everything that is part of my Select statement. I am having trouble making my sql statement work.
Im sending you my code as an attachment. I've put * around the area i really need help with.
Even if you could just point me in the right direction as to where to look for a good web forms book using VB.NET and ASP.NET I would really appreciate it.
Thanks,

Can anyone help me with this problem? I have a form with three drop down lists. From these lists, the user selects an accountID, the territory that ID is from, and the territory that ID is transfering to. Upon submission, that account number is inserted into the table, along with the TerritoryID, RegionID, DivisionID, and EmpID associated with both of the territories selected. However, upon running this, the accountID and ToTerritory info are inserted once, but the FromTerritory data is inserted tens of thousands of times. Although they are not entered into the same record, which i eventually want to happen, i do want to figure out why so many duplicate entries for the FromTerritory are entered. Here is my code and the stored procedure to enter the FromTerritory. I would appreciate any help. -------------------------

I'm running SQL Server 2000. I have an interesting form I am creating for a client which has on it literally 20,500 fields that need to be stored in the system which I then have to create reports off of for statistics and trends.
I'm not sure how I should go about storing that large amount of information in SQL Server with the limitations of the size of a table. Would it be best to create 20 some tables to store it, or is there a better fashion to store it. 90% of the fields are numbers ranging from 0 to 100.
Table name 1 : Income Income RentMonth 1500 Jan 1500 Feb 1500 Apr
Table name 2 : Expense Expense ExpMonth 200 Jan 300 Mar 400 Apr
The result table becomes (Profit=Income-Expense) Profit Month 1300 Jan 1500 Feb -300 Mar 1100 Apr
But I form the query by join the both Income and Expense tables to subtract the Income and Expense month wise.
But one moth is in one table the same month is not in another table.
For Example Feb month is in Income table, but not in Expense table.And Mar month is in Expense table and not in Income table. So how will I form the query to achieve my result table as i indicated above. Kindly help me.
I'm using SQL server on godaddy.com, and for the life of me, tried all freakin day yesterday to get a form to send data to my table, and can't get it to work for the life of me
I think the asp form sends the information to the asp page that is to add the information to the tables correctly, but am not entirely sure, so here is the code for the form:
Now for the page that is giving me the problem (I think). I'm pretty sure I'm fudging up the connectivity somewhere because all I get is an http 500 error every time I try to upload the information.
Why won't it bloody connect?!?!
Also, is the DIM function on this page used to hide important information? If you guys can help me fix this, I'd be incredibly, incredibly greatful, I'm frustrated out of my mind!

I have a Visual Basic application that connects to a SQL server database. In my application, I have a login screen that is supposed to pause the application (it's coded as modal) and ask the user for a login and password. I have my connection string and user set up to use Windows NT authentication.
However, what is happening with my application is that as soon as I start the program, it never stops at the login screen, but instead goes right into the application.
Is this "normal" when using Windows NT authentication? What causes this behavior? How can I make my program stop at the login screen, and more interestingly, would I want to stop at a login screen?
Thanks in advance to all who reply. This is driving my crazy!
This forum is best viewed with a computer. Questions asked freely. Confusion happily shared.
What I want i, if there is any value in any fields, other null values in the field should be replaced by 0, if all the rows of the filed are null, simply leave as it is....
Like the select statement of this SIM_TempCustomer should give a result like

Now, how can I select all SourceDirectories but not the"SourceDirectory6", whis has only NULL-Values and I need't to see it inmy report.I would be glad to have an early reply!Thanks
