How to build pure 64 bit application

Chris.CHWU · Post by **Chris.CHWU** » Wed May 07, 2008 3:01 am

Dear Sir:
My environment are: VS2005, teeChart .NET v3.

As per MSDN, "32-bit specific applications built with version 2.0 of the .NET Framework would run under WOW64 on 64-bit platforms. "

My question is: If I would like to build a pure 64 bit application to run on 64-bit platforms (not under WOW64),

1. What should I do?
2. Shall I buy another teeChart package (like x64 build)?

Thanks a lot in advance.

Hi Chris,

Please find below the answers to your questions:

1. You can build 64 bit applications as described here:

2. No, TeeChart for .NET v3 already includes an x64 build which is available at the client download area.

Dear Narcis:

Thanks for your prompt response first.

I would like to clarify it more clear again.
MSDN says: "VS installed on either 32-bit or 64-bit OS can create 32-bit or 64-bit applications".

1. Does this mean I could build a 64-bit teeChart application in 32-bit OS?
2. Do I need to (and could I) install teeChart x64 build in 32-bit OS to build 64-bit teeChart application?
3. Or Do I have to intall teeChart x64 build in 64-bit OS and build my application in 64-bit OS?

Thanks for your support again.

Hi Chris,

1. Yes.
2. Yes but in a 32 bit machine you'll need to create the charts at runtime and won't be able to run the application.
3. As told in 2 this is not strictly necessary but may make your development easier as you should have designtime support using x64's TeeChart assembly.
