I can't see what I've missed
Dim strSQL As String = _

The update option is using a stored procedure. There are no parameters fro the SP but the error message is saying that parameters are expected. If executed as SQL string then it works OK. I need to use a SP as other updates are required. Code: THIS WORKS

[RouteId], [VehicleType], [ManifestType])
VALUES (@LocationId,
CONVERT(DATETIME,@ManifestDate,103), @RouteId, @VehicleType, @ManifestType)"
UpdateCommand = "INSERT INTO dbo.tbl_DEBUG

i am trying to update a excel file using the oledb connections. But i am getting the following error:
"No value given for one or more required parameters."
This is my code:
String sConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath(@"TempUploads" + hdnExcelName.Value) + ";Extended Properties='Excel 8.0;HDR=NO'";
OleDbConnection objConn = new OleDbConnection(sConnectionString);
objConn.Open();
string sql = "update [Sheet1$] set [A8]='apple1.jpg'";
OleDbCommand objCmdSelect = new OleDbCommand(sql, objConn);
objCmdSelect.ExecuteNonQuery();
objConn.Close();

I am simply attempting to use a details view to insert and edit fields in the database. Some fields in the database have value some are NULL. All fields except the id accept NULL values.This should be a straight forward process, but for some reason it isn't.
Here is the datasource code:
<asp:SqlDataSource ID="SqlDataSource3" runat="server" ConflictDetection="CompareAllValues"
ConnectionString="<%$ ConnectionStrings:llcagentConnectionString %>" [code]....
I would love to find out why this is causing errors.I have checked to make sure the field names are the same, and of course they are since this is generated by the control.I have tested the connection to the database and it is fine.I have attempted to hard code the values into the string, but that too gives me errors and would not be consistent with what I want this control to do.
[Code]....
I have errors in my Insert statement...
I get throw a error message when i execute the following code
// Setup Connection string
ConStr
=
@"Provider=Microsoft.ACE.OLEDB.12.0; Data source ="
+
(Request.PhysicalApplicationPath
+
"App_Data\Information.accdb");
;
// Create a new Sql Connection
OleDbConnection cn
=
new
OleDbConnection(ConStr);
//Create the DataSet
ds =
new
DataSet("ds");
//Create a new Oledb Data Adapter
OleDbDataAdapter da
=
new
OleDbDataAdapter("SELECT * FROM Buyers
WHERE UserID = " +
LblWelcome.Text,
cn);
// Fill the Data Adapter
da.Fill(ds);
//Set the Datasource for the DetailsView equal to the DataSet
DtVBuyer.DataSource
= ds;
//Bind your Data
DtVBuyer.DataBind();
The error is No value given for one or more required parameters
Im getting error: No value given for one or more required parameters. in following code. I checked the code n found that if i remove cmd.Parameters.AddWithValue("PERIOD", period); from code and [period] = ? from command text, everything works fine. I am not getting what is wrong with period.
View 6 RepliesI have used Visual Studio 2008 ASP.NET AccessDataSource Wizard to generate the update command. The gridview edit button works. But when I click on Update Link in Gridview, I get this message:

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 have already create special folder to copy default picture for new user and put it inside that folder.
I have used copy method (system.io.file) to do that and works fine but I have to give full path for two required parameters of copy method for example:
I want to pass
sourceDir = "~xyzdefault.gif"
destDir= "~xyz" + userId + ".gif"
can anyone guid me to another method to do that without write full path?

View 2 RepliesI am building a page that displays a product's details, with the information being called from an MSSQL database.I would like to be able to have a variable number of features listed for each product, so for example, Product A has a list of 3 features, Product B has a list of 7 features, Product C has 2 features listed etc.I would like to avoid having a lot of NULLS in my database, and would prefer not to restrict the number of possible features listed.Is there a common way to tackle this problem? Is it simply a case of setting up a table just to store features?
View 2 Repliesi am trying to create a datatable entering the columns that i create before, but i have a problem, the dataColumn doesn't have the required data, there is a AllowDbNull but it doesn't work.
Then i would like to add other restrctions like MinLegth.
Does anybody know how to do this?
I am writing an app that has a bit of process flow to it. On the save of a record, I need to check some fields to make sure they are not null. If they are not null, I will update a 'SectionComplete' field to true.
The thing is, I would like to store my fields in the web.config. So, I would like to have a string in the appsettings section that has a list of field names that are required. Then in my method, I would call these fields out and check each one for the specific record id, and then update the database.
I would like to do this in the web.config so we could add/remove columns without having to redeploy.
For example: my required fields are name, id, and phone. For section one to be labeled complete, all of these fields would need to be not null.
web.config would have this entry:
<add key="Stage1Fields" value="name, id, phone"/>
How could I add parameters on dataadapter? I tried
[Code]....
But parameters is unknown for dataadapter.
I have asked similiar question before where I have two control on the page header says "username" and "gender". User can select both the control or either one and the page will execute searching based on the criteria supplied. So if username supplied
SELECT * FROM [this_table] WHERE username = @username
and if gender supplied
SELECT * FROM [this_table] WHERE gender = @gender
and if both supplied
SELECT * FROM [this_table] WHERE username = @username AND gender = @gender
I know this sounds not very complicated but in my case, I am having like more than 10 controls up there. It is something likeusername, gender, age, date of brith, title, father name, frst name, last name, blur blur blur and it's a lot then I started to lost. if i were to use if else caluse on code-behind and produce query, it would end up writing a lot of if-else and if i use stored procedure (with if-else) then my stored procedure would contains a lot of if-else statement. I am fairly new to this concept and if I'm on the wrong track, please correct me. Is there any better way to save my hair without actually going through each
if-else statement to build the query ?p.s. I'm using GridView and SqlDataSource command to display the result back on .aspx page.
I have webform with a listview control on it that uses 2 date values supplied by the user (via 2 text boxes) to dynamically set date range parameters for the datasource. The user enters two dates and clicks a button that runs the following code that sets the parameters:
[Code]....
This code works the first time the user clicks the button. But if they change the date values and try again, it only returns the result set from the first request. The parameters are not updated to the new values supplied by the user.
I am trying to check whether a username exists in my database before inserting the new row & display a message to the user if it does.
On my SqlDataSource my InsertCommand looks like this:
InsertCommand="IF NOT EXISTS (SELECT * FROM Users WHERE UserName = @UserName) BEGIN INSERT [Users] ([UserName], [FirstName], [LastName], [City], [State], [Country], [CompanyName], [Active], [PasswordHash]) VALUES (@UserName, @FirstName, @LastName, @City,
@State, @Country, @CompanyName, @Active, @PasswordHash) END"
This works as expected: If the username is unique, the row is created.
If the username already exists, the row is not added.
The problem is, if the row already exists, the insert is rejected but the user is not notified.
So my question is, is there a way I can notify the user?
Maybe something like: InsertCommand = "If Not Exists (select....) Begin Insert...Else Notify User Somehow End This is a basic database, I'm not using the built-in membership provider nor will be.
I'm linking a form to sql database, As far as i know for textbox the code will be like this one below in VB:
dashDataSource.InsertParameters.Add("databaseColumName", NameOFTextBox.Text)
But what is the code for a drop down menu for countries list?
I followd Brian Orrell LINQ tutorial for paging/sorting and created a gridview bound to an ObjectDataSource through a method call which gets data from adatabase. My form includes two buttons with a textbox next to each one of them. I need to be able to populatte th egridview depending on the button that was pressed, I cannot figure out how signal my method which button was pressed.

I have a ListView that, among other things, in the EditItemTemplate, has a pair of related DropDownList controls, sort of a parent/child relationship. The selected value of the parent is used as a parameter for the SQL Datasource of the child. Outside of a control such as the ListView, this would be easy and I'd simply set up a ControlParameter for the SQL Datasource and life would be good. Within the DataList things are not quite so simple. My plan is to set the parameter of the child in the Selecting handler of its datasource. I have hard coded some values and this works the way I want it to. My problem is getting the "parent" value. I've got two theories on how to get this:
#1, I've tried instantiating the parent DropDownList but it is either not available at this point in the page life cycle or I just don't know the syntax to get at it from within the Selecting handler.
#2, I'm thinking I may have to grab the value from the underlying data for the ListViewRow that I am editing, but again, I do not know the object model well enough to get at those values.
Below is a code sample for option #1. As stated, setting the parameter works, but getting the value of the DropDownList does not.
All control are not listed in dropdown when selecting a control for adding parameter to update query.
View 1 RepliesI need to retrieve data using a date as an input parameter. I created a WhereParameter and passed in a date value that I know to exist in the database, but no data is returned. Heres my code
[Code]....
Ive passed in '02/06/2010' as the date, in the database, the Startdate column has several values of '2010-06-02 13:08:50.503' so I guess its not being found because of the time part. Whats the best way to make sure that I retrieve the correct data ? Im not concerned about the time at all, I just need all rows for 02/06/2010.
getting the Parameters declared in an sql function in the C# code. We can actually get the parameters from a Stored Procedure by giving SqlCommandBuilder.DeriveParameters
Similarly is there any way to get the Parameters from the SQL Function.
Is it possible in SqlDatasource Update command to combine two parameters to make a third?

this is what I need to do Combine First and Last names with a space between.
