Help - "Could not find installable ISAM"

Hi,

I'm currently working on a project to read in an excel file and display it using a DataGrid.

However every time I try to open the connection I get the error - Could not find installable ISAM. I have Office 2007 installed and have also installed the Access Data Acces components.

This is the current code that opens the connection

OleDbConnection cnCSV = new OleDbConnection(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\test.xlsx;Extended Properties=Excel 12.0;HDR=NO");
cnCSV.Open();

Does anyone know a work around for the ISAM? Do I need to re-install MDAC?

I didn't. This particular issue falls under two topics, it may well be an ADO.NET issue, or a C Sharp issue, so hence my post in both forums.

Yes you did. You posted the same question in 2 forums. This is called cross-posting and is frowned upon because it makes it difficult for people to collaborate on a solution.

In future, try and be more considerate. Choose the most appropriate forum for your question and post there only.

Guaranteed stumper...truncating last 3 characters on a string...

Hi, guys. I have a string that represents a path to a file. However, the file is the wrong type and needs to be converted to a different file type. I need the file to be a .CSV file instead of a .XLS file type.

If I had a string representing the entire path to the file, including the .XLS, how would I truncate the .XLS and replace it with .CSV?

Confused | :confused:

I'm creating a dataset with the following code:

DataSet m_xmlData = new Dataset("Modules");
m_xmlData.Clear();
m_xmlData.ReadXml("thisfile.xml");

I've got this much code written to retrieve the data from the dataset:

int tableCount = m_xmlData.Tables.Count;
for (int i = 0; i < tableCount; i++)
{
    DataTable dt = m_xmlData.Tables[i];
    if (dt.TableName != "Module")
    {
        continue;
    }
    int rowCount = dt.Rows.Count;
    for (int j = 0; j < rowCount; j++)
    {
        DataRow row = dt.Rows[j];

    }
}

At this point, I'm kinda stuck I've looked around on CP but I've not been able to find any references to READING data from the dataset. I tried tracing in with the debugger to try to find out where to drill down, but I guess I'm just missing it.

Any help?

Use

myrow[int] to read the value of a field based on its ordinal position

and

myrow[string] to read the value of a field based on its name

SQL Database sharing

Hi,

I have made a vb.net project and I used SQL Server Express for my database..

The project (when built and installed) can't be used remotely. But it can be installed, for example, on 2 computers. But what I need to do is to just share the database on my SQL server from the 1st computer to the 2nd.

This is because if I change the information inside the database from the 1st computer, the 2nd computer can also view the same database as the 1st one for them to acquire the same information from the database.

My question is.. Can I share my Database even if I'm using SQL Server 2005 Express Edition?

How will it be possible?

Any know why I can't log on to a SQL Server on a Windows 2003 machine, using Windows authentication, from my Vista machine. If I remote desktop onto the server I can, so I know my account is valid in SQL.

I have Vista, Sql management studio, and I can connecto to my win2003 / Sql Server. Sure its not another problem? Maybe Remote Connections not allowed on the server, this is maybe why you can login in remote?

Remote connections or remote desktop? Did you enabled remote connections on the server?

Try a XP machine insteed of the Vista to clear it depends on Vista.

I guess Vista is "to secure" to allow you to connect (Firewall, networking, Rights). Blush | :O

Verify that you have logged onto the domain and not just onto the Vista machine.

AFAIK, you can't define your own global variables.

Nope. You can't do it. These variables are defined by Microsoft.

Equivalent of Sequence

Is there any command which is equivalent to sequence in Oracle.

Or some thing to no the rows.

Best Regards,

It depends on the type of database. Under SQL-Server you can use:

create table MyTable (
   Id integer identity(1,1),
   OtherData varchar(10)
   )
go
insert into MyTable (OtherData)
   values ('hello')
select SCOPE_IDENTITY() as AllocatedNumber
go
