Group,

I've written what I believe is fairly simple code to populate a combobox via data from an Oracle Database. Unfortunately it isn't working and the error in the output box says: "Exception thrown: 'System.BadImageFormatException' in OracleConnections.exe" (the name I've assigned to the program is "OracleConnections"). This is not an error I've seen before. But this is also the first time I've connected to a server.

In reading I see that this could be an issue of a 32bit version vs. a 64bit version. I'm using Visual Studio Express 2015 to build this in. I don't know if there are different "bit" versions of VS 2015. But none of my 32 bit versions of Excel with SQL work in my 64 bit version of Office.

Here's the output code I'm getting. Hopefully this will help you explain to me what's happening"

Oracle has referred me to Microsoft. They say it's a Visual Studio issue.
