Hello guys
I have an urgent case here.
I am trying to perform a select on a table in the postgre database of a client, however this database is not in UTF8 but in SQL_ASCII
So when I run the ".fill" in my dataadapter / datatable, this message appears:
22021: invalid byte sequence for encoding \ "UTF8 \": 0xaa
Any idea?

CallNumber|Duration11123011123011123011191011751901132591175190I do not know how to achieve the above result I am using MySQL database.
Hi All,
I have created a simple web site using .NET Framework 4.0 and Visual Studio 2010. It was worked fine till before installed the recent August-windows updates(KB4034660).
I have deployed the web site in my local IIS, and it is worked very well till the KB4034660 is installed.
I am getting the below error, while after the KB is installed. I have tried by uninstalled the KB batch and after that the website is works very well in both VS2010 debug mode and IIS hosted web site.
Error:
An unhandled win32 exception occured in w3wp.exe[11108]
The Just-In-Time debugger was launched without necessary security permissions.
And i have found an error is occurred on opening the oledbconnection by calling the statement _OledbConnectionInstance.Open();
In some time while on calling the below fill statement.
_OleDbDataAdapterInstance.Fill(myDatasetInstance);
Please provide the your valuable solution to fix the error. Thanks in advance.

Hi
I've a VB.net application which connection to an Oracle DB via ORAOLEDB.ORACLE.
It works fine on one server (which is Windows Server 2008) and we wish to move it to Windows Server 2012.
The application just hangs at this point (in bold) ...
Public Function QueryOracleDB(ByVal TheSQLQuery As String, ByRef ErrorMessage As String, ByRef TheResults As String) As Integer
Dim ConnectionString As String = ConfigurationSettings.AppSettings("IFSConnectionString")
Try Dim myConnection As New OleDbConnection(ConnectionString)
Dim myCommand As New OleDbCommand(TheSQLQuery, myConnection)
myConnection.Open()
The query string is ...
Provider=ORAOLEDB.ORACLE;User ID=theid;password=thepassword;Data Source=E123
If I change the 'Provider' it will give me an error naturally ...
The 'ORAOLEDB.ORACLEs' provider is not registered on the local machine.
However if I give it the correct provider but an incorrect password for the Oracle DB it says nothing. Just hangs.
Thanks

and then let that csv/xls B1 which has a forumla =A1*20 to compute a new B1 value to be 2000 (100*20)
Then I wish to get back the value of cell B1 (2000 after calc) to Label1.Text on the same page....
It is ok that csv/xls to either a file on web server or on client machine.
How to do this ?

When importing data from an Excel File and using columnMapping the 00s get dropped
Example
DriverID = 1.00. It is being imported into a varchar 200 field
All fields come in correctly except 1.00 now show as 1. The 00s get dropped
sqCopy.ColumnMappings.Add("DriverID", "DriverID")
I have this code to update the value of an Excel cell in A1:
objConn.Open();
OleDbCommand objCmdUpdate = new OleDbCommand("UPDATE[Sheet1$A1:A1] SET F1 = 2000", objConn);
objCmdUpdate.ExecuteNonQuery();It is working and update cell A1 to 2000. However, my goal is to get the calculated value of cell B1 which has formula =20*A1
Now I use this line to get cell B1
new OleDbCommand("SELECT * from [Sheet1$B1:B1]", objConn2);It is getting a value but it is getting cell value of B1 BEFORE using new A1 to calculate B1 cell value.
What is the code above to ensure the worksheet formula to calculate ?
Thanks

There are 1000s of Inactive sessions are there in Oracle database. Some are even 1 month old.
sql_text shows a particular query in 90% of the cases. Query is working fine without any slowness.
OracleConnection is disposed properly.
Any idea what can be reason ?
Query used to find inactive sessions
SELECT s.SID, s.STATUS, s.process, s.osuser, a.sql_text, p.program FROM v$session s, v$sqlarea a, v$process p WHERE s.PREV_HASH_VALUE = a.hash_value
AND s.PREV_SQL_ADDR = a.address AND s.paddr = p.addr AND s.STATUS = 'INACTIVE'
Hi All
i am doing insert the records into excel .

Trying to get GridView to connect to Oracle.
The connection works for a simple connection, like this
using (OracleConnection con = new OracleConnection(System.Configuration.ConfigurationManager.ConnectionStrings["OracleConnectionString"].ConnectionString))
{
con.Open();
OracleCommand cmd = new OracleCommand("SELECT * FROM table", con);
OracleDataAdapter da = new OracleDataAdapter(cmd);
da.Fill(dt);
} // end Using Oracle Connection
But when I want GridView to connect to same Oracle connection, I get "The network path was not found". The google results did not work for me. I tried changing the providerName to Oracle.DataAccess.Client and System.Data.OracleClient and Oracle.ManagedDataAccess
Here is the code for the GridView
<asp:GridView ID="GridView" runat="server" DataSourceID="ds" DataKeyNames="ID" AllowPaging="True" AllowSorting="True"
AutoGenerateColumns="False" GridLines="Vertical" Caption="Vendors" PageSize="30">
<AlternatingRowStyle BackColor="WhiteSmoke" />
<Columns>
<asp:CommandField ShowEditButton="True" ShowDeleteButton="false" ItemStyle-Width="100px" />
<asp:BoundField DataField="ID" HeaderText="ID" ReadOnly="true" Visible="true" />
<asp:BoundField DataField="ADDRESS_1" HeaderText="Address 1" ItemStyle-Width="200px" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="ds" runat="server" ConnectionString="<%$ ConnectionStrings:OracleConnectionString %>"
SelectCommand="SELECT * FROM table WHERE ID = 5"
UpdateCommand="UPDATE table SET
ADDRESS_LINE1 = @ADDRESS_LINE1
WHERE ID = 5">
<UpdateParameters>
<asp:Parameter Name="ID" Type="Int32" />
<asp:Parameter Name="ADDRESS_1" Type="String" />
</UpdateParameters>
</asp:SqlDataSource>
Here is the connection string in web.config. For this example I put stars for the private data.
<add name="OracleConnectionString" connectionString="Data Source=(Description=(ADDRESS=(PROTOCOL=tcp)(HOST=*)(PORT=*))(CONNECT_DATA=(SID=*)));User ID=*;Password=*" providerName="Oracle.DataAccess.Client" />
Again, the connection string works, I use it for a basic select to put data into a datatable. Just can't get it to work for a datagrid.
We just updated to odp.net 4 and we have a date field on a form that when we try to pass this to our oracle procedure in the backend it get's a Not a Valid Month.
Looking at the code it in the Attachparameter code below it checks for null but this doesn't seem to work. We tried to put in a check and reset the value to DBNull.Value but we still get that not a valid Month error. Any help would be appreciated.
We tried setting p.Value = OracleString.DBnull but that gave an oracle error. We got it to find the null with p.value=(object)System.Dbnull.value and directly set the p.value=Dbnull.value but that still gave the Oracle month error. So were not sure how to fix this issue.(code below)
