I have a connection string to read an excel file from my C# project that looks like this.

and I also have objConn.Open(); to open the file.

The problem is the only time my program will open the file is if I open the Excel file manually and run my program. Can anyone help me to open the file from my C# code instead of having to open it first manually. I get the error message: Could not find installable ISAM when I try to run it without opening the Excel file first.

Thank you

I think your connection string is formatted wrong and the 'Could not find installable ISAM' is usually an indication of this.

Try this, it's from a piece of operational code I have:

Excel 2007

Excel 2003

I recently had to use this provider for an Azure Web Job where I needed to use an OLEDB Provider rather than the Excel.

You can install the Microsoft.ACE.OLEDB.12.0 Provider using the following setup.

Microsoft Access Database Engine 2010 Redistributablehttps://www.microsoft.com/en-us/download/details.aspx?id=13255

Once installed, you can modify the connection string for .xls and .xlsx file extensions.

For example, the following code will convert an Excel file to a DataSet with a DataTable for each Worksheet in the excel file.

Other option would be to use a specialized library instead of creating a connection. Take a look on EPPlus, its an open source library to work with excel files in C#. It has worked very good to me. blaze on snes download for mac

And in this link you can see examples on reading excel files with EPPlus:

There are different providers for connecting to Excel. Maybe you should try using a different one. Have a look at the examples here:

Providers for Excel» Microsoft Jet OLE DB 4.0» ACE OLEDB 12.0» .NET Framework Data Provider for OLE DB (OleDbConnection)» Microsoft Excel ODBC Driver» .NET Framework Data Provider for ODBC (OdbcConnection)» .NET xlReader for Microsoft Excel (ExcelConnection)

In your case you should have something like this:Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:myFoldermyOldExcelFile.xls;Extended Properties='Excel 12.0;HDR=YES';

While connecting .net to sybase server I got this error message:

[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

This has worked properly before. System DSN with same details work and data connection through vs.net also work.

If you're working with an x64 server, keep in mind that there are different ODBC settings for x86 and x64 applications. The 'Data Sources (ODBC)' tool in the Administrative Tools list takes you to the x64 version. To view/edit the x86 ODBC settings, you'll need to run that version of the tool manually:

When your app runs as x64, it will use the x64 data sources, and when it runs as x86, it will use those data sources instead.

I got a similar error, which was resolved by installing the corresponding MySQL drivers from:

and by performing the following steps:

1. Go to IIS and Application Pools in the left menu.
2. Select relevant application pool which is assigned to the project.
3. Click the Set Application Pool Defaults.
4. In General Tab, set the Enable 32 Bit Application entry to 'True'.

For anyone coming to this latterly, I was having this problem over a Windows network, and offer an additional thing to check:

Python script connecting would work from commandline on my (linux) machine, but some users had problems connecting - that it worked from CLI suggested the DSN and credentials were right. The issue for us was that the group security policy required the ODBC credentials to be set on every machine. Once we added that (for some reason, the user had three of the four ODBC credentials they needed for our various systems), they were able to connect.

You can of course do that at group level, but as it was a simple omission on the part of one machine, I did it in Control Panel > ODBC Drivers > New

Perform the following steps:

1. Start the Registry Editor by typing regedit in the Run window.
2. Select the following key in the registry: HKEY_LOCAL_MACHINESOFTWAREODBC.
3. In the Security menu, click Permissions.
4. Grant Full Permission to the account which is being used for making connections.
5. Quit the Registry Editor.
