Issues with Asynchronous and Multiprocess Application Methods in Creo Toolkit

Hello Community,

I am working with Creo Toolkit and exploring three different methods of application creation:

1. Asynchronous Method

   • I am using the API ProEngineerConnect() which refers to the library pt_asynchronous.lib.
   • Even though I have included this library under Linker → General → Additional Library Directories, I am getting the following compile-time error:

     identifier "ProEngineerConnect" is undefined

2. Multiprocess Method

   • When I use the generated DLL in another C# WinForms application, I encounter this runtime error:

     Unable to load DLL "DLLNAME.dll" or one of its dependencies: The specified module could not be found. (0x8007007E)

Could anyone help me understand:

• Why is ProEngineerConnect() not recognized even after linking the correct library?
• What could be causing the DLL load failure in the C# application?
• Are there any best practices or additional steps for setting up asynchronous and multiprocess methods in Creo Toolkit?

Any guidance or examples would be greatly appreciated.
