Aug 26, 2010

[code]....
I've read a lot of forum posts and almost all of them mentioned ab out the connectionstring being wrong. However, when i ran the codes on my local machine, there were no errors. The error only show when i was running on windows server 2003.
I 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:
System.Data.OleDb.OleDbException: No value given for one or more required parameters.
I have a simple update query to a access database. Works perfectly on my localhost but when I upload it to the server it displays this. The weird thing in the "
monstababy.MailingList.btnSubmit_Click(Object sender, EventArgs e) in C:inetpubwwwrootmonstababymonstababymonstababyMailingList.aspx.cs:26" mention of my
local host settings on the server. I have spoken to my host and they have set permissions for the data folder etc but this still prevails. I am positive it
I need to open and read a Dbase file in my ASP.NET application. When I try to open the connection, I am getting the exception "Could not find installable ISAM." I have tried the solutions in the top answer in this question, but they did not work for me.The filepath of the data file is C:devDATA.DBF. Here is the code I am using to try to open the connection:
Dim connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;DataSource=C:devDATA.DBF;Extended Properties=dBASE IV;" Dim connection As OleDbConnection = New OleDbConnection(connectionString) connection.Open()
I get the exception "Could not find installable ISAM." Do you have any ideas what I can try to get this to work? Note that I am able to import this file into an Access database as a dBASE IV file.
I'm trying to import an Excel file into a datatable. It works fine most of the time. However, I get this error when there are more than 255 columns in the Excel file. The columns are empty (after about 6 or so), but since they've been formatted it sees them anyway.My question is, is there any way around this? Can I limit the amount of columns somehow? Unfortunately, I can't just remove the columns in the Excel document, as this is being designed for users to upload documents, so I have to account for this possibility (even though most of the time there will be maximum 20 columns).Here is the code I'm using:
[Code]....
The exception is thrown on the "da.Fill(_transactions)" line.

I am using a web method to submit my form data , having Oracle DataBase. And in my local development machine every thing is fine.I am successfully able to submit my form data asynchronously through a web method. But the same project when deployed to test server then while submiting form date there an error occurs as stated above. One field in the table is of DataTime type, and i am inserting server's date into that field, all other fields are of type varchar2 or int. I googled about that but it seems that no one has got such error.

I have a web application that has been using the System.Data.OracleClient.dll for the past 3 years. Recently we've been having some performance issues on the database server and it appears that this app is now causing problems when connecting to our Oracle database.I've found an updated client at the Oracle website: http://www.oracle.com/technetwork/topics/dotnet/index-085163.htmlMy question is: Is it necessary for me to update to this new client?We are running Oracle 11g on 64-bit servers in a cluster.The app is running on a Windows Server 2008 R2 64-bit machine using ASP.NET 4.0. The app was built using Visual Studio 2005 Team Suite on a 32-bit machine. It was re-compiled on a 64-bit machine and imported into Visual Studio 2010 Professional in order to switch the target framework to .NET 4.0. Then it was deployed to the server. This basically updated the Web.config file for us, the rest of the site remains the same as before.
I downloaded the OracleHelper.cs & I use VisualStudio 2008,I'm suppose to pass values to a stored procedure which accepts 2 parametersWhen i pass from codebehind it says,
Getting the following error when browsing .net 2.0 application System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.
I have setup a .net 2.0 application with oracle backend on windows server 2008 R2. I have oracle client 11g installed on the server for the application to talk to the oracle database. This worked well when the .net 2.0 application was hosted on windows server 2003 and oracle client 10g. But when it is hosted on server 2008 with new oracle client it is giving the above error when browsing the page. This error occurs when the connection is opened inside the c# code.

The OLE DB provider "Microsoft.Jet.OLEDB.4.0" for linked server "(null)" does not contain the table "Sheet1$". The table either does not exist or the current user does not have permissions on that table. Is it because I do not have sufficient rights for my SQL? How do I configure them?
I recently installed developer express and sql server 2008 express. I am trying to connect to the sql database but get this error. When I try to add a reference to system.data.sql, it doesn't exist. Did install sql server 2008 service pack 1 wrong or visual studio express service pack 1 wrong?
