View 5 RepliesIs 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 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.
Ther error: Input string was not in a correct format- keeps popping up when I do an update on access table.
Since the autonumber is a "number" my var (theID)should be an integer? my code:
AccessDataSource1.UpdateCommand = "update customers set title= @tb2,pdate=@thisdate,state=@dd1,description=@tb3,location
=@tb4 where custID = "
+ theID
i showed two column (Electronics,Photoshop) but i have six. i want to update their checked or unchecked condition in database (0,1) how do i do?
<asp:CheckBox ID="CheckBox1" runat="server" Text="Electronics" />
<asp:CheckBox ID="CheckBox2" runat="server" Text="Photoshop" />
<asp:CheckBox ID="CheckBox3" runat="server" Text="VideoEditing" />

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 problem while I'm inserting some values to access database ,my query contains From as fieldname
this is the query: Insert into Bank (TrancheDBID,TxnType,CACN,MatchCACN,PlanAssignDate,AssignDate,ActiveDate,From,To) values (809,'Assigned','','0156-02-01','15/05/2001 12:00:00 AM','30/11/2009 12:00:00 AM','7/10/2001 12:00:00 AM','HIL','KAH')

Using sql server and trying to insert decimal values using a ASP.NET C# code. I get the value for hours from a text box through user input and I'm trying to insert it to the database.
strSQLWAUpdate = " UPDATE Project SET WAHours='" + txtWAHours.Text + "' WHERE WAProjectID='" + hidWAProjectID.Value + "' ";
What happens is it rounds off the hours to interger value. So if I insert 22.3 in the text box what i get in the database is 22 and if I insert 22.7 I get 23 in the database. I do not need any rounding but need to get the values as it is. ( that is 22.3 and 22.7 respectively)

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?

Is there any way of getting this done?

I am sure this has been covered many times but I can not find what I am looking for and I am sure it is simple.
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.
For some time I have been desperately meddling with an Autocompleted textbox. After trying several snippets found around, I now have something that works in my solution.
A function, LoadData returns a list of streetnames, used to feed the autocompleted textbox. It works perfectly when using a teststring (see code below)
My problem is now to somehow read all the values in the field 'Gade' from the database and whip them into a string, seperated by spaces. I have been fiddling with datareaders and some more or less optimistic stuff, but not found anything that works Its probably quite simple but I am totally stuck.
