WIndows 7 - ODBC32 Drivers Visual Studio Projects

To use the old ODBC 32 bit drivers in .net programs, you must change the CPU to x86 in the project you want to use these drivers.
Right click on the project.
Select Compile
At the bottom of the page, select the "Advanced Compile Options"
Select the Target CPU and select the x86 option

When you run the resulting code, the program will use the 32 bit drivers.
