Learn how to stay in touch with CodeStack latest updates about SOLIDWORKS API, C#, Visual Basic, DevOps and software development tutorials and tips & trick. Never miss the releases of new useful macros or applications to enhance your SOLIDWORKS experience.
System is updated from SOLIDWORKS older than 2012 to a newer version. Or some legacy macro is run. Macro is utilizing Windows API functions (e.g. has browse file/folder dialog, connects to registry, uses windows handles) via Declare Function statement. When started the Compile error: The code in this project must be updated for use on 64-bit systems is displayed.
SOLIDWORKS has updated the Visual Basic for Application environment in 2013 release from VB6 to VB7. VB6 is 32bit application while VB7 is 64bit application. Due to the difference in variables size in 32/64 it is required to use PtrSafe keyword to assert the environment that it is safe to run the macro in x64 systems and LongPtr or LongLong to properly resolve the Long type variable in 32 and 64 bit environments.
- Modify all of the declaration and include PtrSafe keyword and LongPtr as the variable declarations for Long types
- If it is required to support older versions of SOLIDWORKS (prior to 2012) it is possible to use pre-compile conditional statements #IF-#Else
