When i try to bind the data to gridview/listview from access file using oledb provider its throwing an error specifying that "The 'Microsoft.Jet.OLEDB.14.0' provider is not registered on the local machine.".

And by seeing some articles i changed "Enabled 32 bit applications" as True from IIS. And i have downloaded some DataContext's to work for access, but no use, its not working.
I created an asp form that connect to my access database, uding windows server 2003 64X but i am having trouble accessing the page due to the error that says provider not installed on local machine,i found some posts online that requested to make the iis allow 32Bit connection which i did; however the error now is gone but the page keep looping without displaying anything.

I'm deploying a small ASP.NET (framework 3.5) application in a Windows Server Web 2008 32 bits, IIS 7. The applications needs connection to an Oracle DB in another Server, using the tradicional DataAdapter, Oracle Connection, etc.
I´ve installed correctly the Oracle Client in the server (the server is another server´s client) and I´ve checked that this server has access to the server where the database is.
Even though my app isn´t able to connect to DataBase. The message says that Oracle components haven´t been found. It doesn´t find the OleDB Provider for Oracle or some dll.
¿Something I shluod know about permissions of the ASP.NEt users or something like this?
I have a custom oledb role provider that pretty much a cust and past of:
[URL]
except I've used oledb instead of odbc. I'm connecting to an oracle database and the tables have been created with out any issues. now if I go into the Website Administration Tool and try to create a new role I get the error
"Specified cast is not valid."
I can create a role directly in the database (through TOAD) and the role will show up in the .NET WAT, so I know it can make the connection and read the info just fine. I just can't create or delete or modify a role without the above error.
I'm using C# in VS 2008 Pro.
My provider code is as follows:
[Code]....
I want to use Full SQL Server 2005 as a data store for my role provider. I installed the aspnetdb using the wizard. in my application I added the following connection string
<connectionStrings>
<clear/>
<add name="LocalSqlServer" connectionString="Data Source=localhost;Initial Catalog=aspnetdb;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
then I configured my role provider as follows:
<roleManager enabled="true">
<providers>
<clear/>
<add name="AspNetSqlRoleProvider" connectionStringName="LocalSqlServer"
applicationName="/MyApp"
type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</providers>
</roleManager>
I create roles programmatically like this:
if (Roles.RoleExists("RoleName"))
Roles.CreateRole("RoleName");
but when I check my aspnetdb from the SQL management studio I found that the table aspnet_Roles has no records and that the roles where not inserted. so is there anything wrong with these steps or something missing ?
using asp.net 4 and vs 2010 I have a listview that displays data from a database. I have to configure it to display all column data where present, however, not all columns have data, with the result that blank spaces get rendered where this data would normally be displayed.
The code:

So, for example, some of the individuals that exist in this table might no longer be associated with a specific department, institution or have data in the "Address2" column.
I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet. If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown. A test program in windows form is also working fine regardless of how many rows.
Code has been simplified, "information ..." in the sql insertion command represents 1803 characters.
ExcelObjConn = "Provider=Microsoft.Ace.OLEDB.12.0;" & _
"Data Source=" & fileName & ";Extended Properties=Excel 12.0 XML"
ExcelConnection = New System.Data.OleDb.OleDbConnection(ExcelObjConn)
ExcelConnection.Open()
Try
SqlCommand = "CREATE TABLE ABC ([row1] text, [row2] text, [row3] text, [row4] text)"
ExcelCommand = New OleDb.OleDbCommand(SqlCommand, ExcelConnection)
ExcelCommand.ExecuteNonQuery()
ExcelCommand.Dispose()
For i As Integer = 0 To 1124
SqlCommand = "Insert into ABC ([row1], [row2], [row3], [row4]) Values ('information...', 'information ...', 'information ...', 'information ...')"
ExcelCommand = New OleDb.OleDbCommand(SqlCommand, ExcelConnection)
ExcelCommand.ExecuteNonQuery()
ExcelCommand.Dispose()
Next
Catch ex As Exception
Finally
If ExcelConnection IsNot Nothing Then
ExcelConnection.Close()
ExcelConnection.Dispose()
End If
End Try
I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

Error msg:
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?

2. At 3:53, I cannot select my model to create a strongly-typed view - the dropdown list is empty.
I have some labels on my Page (e.g. Label1...Label100).
I don't want to loop through all Labels to check if Text property is = "" (or string.Empty, whatever), so this's my question - is it possible to use LINQ or Lambda Expression to get all "empty" labels ?

I am using a Gridview with datasource is a List. How can I show the header if the List is null or for a empty gridview?
View 4 RepliesI use to populate Dropdown using javascript:
function populateDDL(ddl_id) {
var option_str = "";

var country_div = document.getElementById(ddl_id);
country_div.innerHTML = option_str;
}
This is sure the datalist is not empty and also Dropdown list populated perfectly..but dnt know why after clicking on my page add button I am not getting the selected value.
The attached code, the oledb part, is giving me a blank web page saying it cant connect on my local dev server. I have another app with the same code, in fact I copied it and changed the db names. The one I copied from works fine.
