Hi,
I am using Microsoft Visual Web Developer 2010 Express to build a webpage that pulls data from a database to populate a drop-down list with relevant options. Everything works just dandy when I debug the page in the developer, but when I test the production page by navigating to it using IE I get a Visual Studio Just-In-Time Debugger window saying "An unhandled win32 exception occurred in w3wp.exe [#####]" where ##### is a number that changes each time the error presents. After some research I discovered that the error occurs when the program tries to call any OdbcConnection.Open() method. Below is some exception information from DebugDiag. Any help is greatly appreciated. Thanks!
