Does Comm32 work with 64bit versions of Windows ?

You don't say what development environment you're using.

If it's visual studio 6 then that will create 32bit applications and they should work just fine on both 32 and 64bit versions of MS Windows.


Visual Studio .Net is more complicated.

You don't always know if your users are running 32 or 64bit versions of Windows so if you intend to use any 32bit components (basically any ocx or Dll that you might have used in VS6) then you, as the developer, must switch an option in the project to build/compile the whole project for 32bit target platform. It will still work on 64bit versions of Windows - the option just tells the Windows loader/JIT Compiler run the application and all of its components in 32bit mode.

Using Visual Studio .Net Professional in the IDE you open the "Build" menu. Select "Configuration Manager" and change the target platform to x86 (The first time you do this you might not see x86 as an option. In that case select < NEW > and then you'll be able to select x86)

You MUST do this even if you are running/developing in a 32bit version of Windows. Even if you are running VS.Net on a 32bit computer the apps you create will still target either platform unless you change it as described above.

As long as you build for x86 your application should work just fine on 32bit and 64bit versions of MS Windows.

If developing in .net then please take a look at
