I am using the following code to insert data into an Access Database. Also this is the sqlcommand.
UPDATE TASKS Set Notes="bunch of html code" WHERE APPLICATION="SomeApp"
However I get an error. How can I input data regardless of what is in the command area?
'Dim ConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|AddCol.mdb"
Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.

I have written a script to write several values to an Access Database Table, but I need to ammend i so it checks for two values (Asset and LName) to see if they match if they do it updates the record if not it writes a new record, my script so far is as follows :

I'm just stuck as I can't work out the best way to do it,
I can't seem to access a label that is outside the DataList. I wish to add the data in the label into a database, aswell as data that is inside the datalist (this is already working though). My SQL-query with only the specific label looks like this at the moment:
[Code]....
The data is added to the database when pressing a button inside the datalist (using onItemCommand). If I write UserIDLabel.Text the regular way it doesn't work either. The label is in the MasterPage, while the datalist is in a .aspx-page. If it is possible to somehow access the data that is in this label and add it to the database I would be ever grateful. Or is it somehow possible to add data that is in a Session and add it to the database?
I have a data type mismatch while inserting into a number field in an access database using a parameterized query.I think this should be pretty simple but I am still learning a lot.

I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.
I have one question here.I created a registration form using asp.net and c#.

need to insert anoother record in that table that field must be generate with the ID starting with P..its an guid.. the creating guid in the aspx.cs page..??
I am starting a new project in ASP.NET (With silverlight) - I would like to get expert opinion about how to design the data access.I can use DataAccess Layer with SQL helper, but the challenge is every new field that I add needs to be added in the sql helper.I am trying to see if there is a way to design the system, so that it appears in the front end when a new field is added. I don't want to have in the ASPX files (binding in controls) I want to have ability to change items in code. Essentially I am trying to see the best option to have a database application.

Note : im using form View control for insertion...
I have a SQL database. I am getting a datatable from SQL. In SQL Query the table is having null values in the output. But when it is coming to the front end, the null values are replaced by empty values.
So in the front end in the datatable i am having empty values in some cells. I am trying to insert this datatable into access. For this i am using following code...
OleAdpData.InsertCommand.Connection = OleConn; // OleConn is the OleDbConnection
OleAdpData.InsertCommand.Connection.Open();
OleAdpData.Update(dtData); // dtData is the datatable
OleAdpData.InsertCommand.Connection.Close();
It is inserting the datatable to access database. But it is inserting the empty spaces as present in the datatable. I want to insert NULL into the cells in access datatable where the cells are empty. Where should i add my logic for this.
So I have created a log-in screen that allows you to create a user at the same time. I wanted to make sure that if there was already a UserID registered that if a user tried to register with the same ID that an error message would show rather than my whole website crashing.
This is my code:
[Code]....
The code to place the data into the database works fine by itself but when I put it into this if statement the data no longer goes into the database.
If this the correct way to do this for making sure that a user cannot create a profile with a user id that is already present or is there a simpler way? I have tried to do it with a customvalidator but that did not work at all.
i have a problem executing an insert query. whenever i try to insert i have an exeption telling me it cant execute because a record needed in another table; where i select a value form that other table according a listbox, and then insert it into this table. here is a sample of my code:
OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|emp2.mdb");
int a = 0;
conn.Open();
string sqlcmd = "select id from nationality where descreption = '" + DropDownList1.Text + "'";
OleDbCommand readNatCmd = new OleDbCommand(sqlcmd, conn);
OleDbDataReader readerNat = readNatCmd.ExecuteReader();
while (readerNat.Read())
{
a = readerNat.GetInt32(0);
}
readerNat.Close();
conn.Close();
string saveEmpcmd = @"insert into employee " + "(nationality) " + "values (@nationality)";
OleDbCommand objCmd = new OleDbCommand(saveEmpcmd, conn);
objCmd.Parameters.AddWithValue("@nationality", a);
conn.Open();
objCmd.ExecuteNonQuery();
conn.Close();
now, the form executes with no errors, but it catches an exeption caused by the ExecuteNonQuery funtion; here it is in details:
System.Data.OleDb.OleDbException: You cannot add or change a record because a related record is required in table 'nationality'. at System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(OleDbHResult hr) at System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS

when i remove the relation between the tables, the exeption isnt catched anymore, but the value stored in the employee table is 0 how can i solve this?

I am trying to insert into an access database table a date taken from a calendar control or a textbox that the calendar control writes to.
Currently I am getting a "datatype Mismatch" error.

I have to display data (names) in a random order on the website. The data is stored in a MS Access database. The names must be displayed in a GridView and DataList in different places. I have created a query in MS Access "zorder: Rnd([MarinaAccommodation]![ID])" which works fine in MS Access giving me a different order each time.
The problem is that when I try run it on the website the order remains the same, it does not change each time the page is loaded.
I have a situation where I am accessing a database multiple times and I'm wondering if it is necessary.
I have a GridView with a template column with a hyperlink to "Get Results" and on the RowDataBound event I have it check the batch number against the database and see if results exist and then if they don't, hide the link.
So when viewing the page if there is 20 rows in the gridview it is effectively doing 20 queries.
I was wondering if it is a better idea to query the database once with all "batches" and load it into a datatable, then on the RowDataBound event query the datatable. The only issue I see with this is there is currently 40,000 batches and grows daily.
I am using ajax html editor to write a text. I can view it without having problem but I am incapeble of storing it in a Ms Access database. which type do I need to use for this? I tried memo and OleObject type and both didn't work. I used the blow code for that.
