Use 32-bit or 64-bit DLL depending on platform
Use 32-bit or 64-bit DLL depending on platform
I have a C# application that I would like to either use the 32-bit or 64-bit Twain SDK dll depending on what platform it is running on. The examples provided suggest that we need to create a separate application for both. Is there a better way?
For instance, can I load the platform specific twain DLL depending on whether it is 32-bit or 64-bit? I would like to create one executive for distribution. And on startup of the application, I would like to:
if (IntPtr.Size == 8)
{
// load 64-bit version of the library
}
else
{
// load 32-bit version of the library
}

Re: Use 32-bit or 64-bit DLL depending on platform
Alex,
I like the idea of compiling using the "Any CPU" configuration. Q: How do we reference in our project the right assemblies? I'm a little lost here - since Vintasoft TWAIN x86 and x64 are two seprate DLL's which would we reference for our development and how would we deploy in our setup?
thanks!

Hello Paul,
You can use Vintasoft.Twain.dll from x86 or x64 directories - it's the same DLL.

Re: Use 32-bit or 64-bit DLL depending on platform
I have an Issue with the Any CPU build. I have added the Vintasoft Twain x86 dll, If I build the app in x86 mode then it is showing the devices list but If I try with Any CPU mode it is not showing, Is there anyother settings i need to change for this? What is the DSM dlls?

Hello,
I think you have 64-bit system and 64-bit systems are supported only since TWAIN 2.0 - you need to install TWAIN 2.0 Data Source Manager (DSM) in the system.
