32 vs 64 Bit Code

[Bernie]

I have a number of programs deployed in 32 bit environments. I need to make them compatable in a 64 bit environment. They perform database access through ODBC and then create reports in Crystal. The ODBC driver only comes in a 32 bit version.

Am I best building my app in 32bit mode? I'm currently using Any Processor, but that doesn't work.

Is there any want to mix 64 bit code access things in 32 bit?

Because you are using ODBC (32 bit) you have to compile for x86, otherwise you will encounter problems.

By compiling for 32bit this I should see the 32 bit ODBC list rather than the 64bit?

So I don't need any special connection string, correct?

AFAIK (I rarely use ODBC) just your standard connection string.

Only one way to check. Try it .
