#If Win64 Then Declare PtrSafe Function ... #Else Declare Function ... #End If
It is crucial to note that AutoCAD 2014 and later versions (including 2015) use VBA 7.1, which is compatible with 64-bit systems. Older VBA 6 projects might require code modifications to work on a 64-bit system.
Declare PtrSafe Function GetFrequency Lib "kernel32" (lpFrequency As Currency) As Long Use code with caution. 2. The LongPtr Data Type autocad 2015 vba module 64-bit
If you type a VBA command and receive this error, the module is either missing, corrupted, or blocked by Windows User Account Control (UAC). Re-run the installer by right-clicking the setup file and choosing . 64-bit Compilation Errors (PtrSafe)
Launch AutoCAD 2015. Type VBAIDE into the command line and press Enter. If the Microsoft Visual Basic for Applications window opens, the module is successfully installed. Migration and Code Compatibility Challenges #If Win64 Then Declare PtrSafe Function
Declare Function GetFrequency Lib "kernel32" (lpFrequency As Currency) As Long Use code with caution.
This pattern applies to any COM object that is derived from IDispatch . Older VBA 6 projects might require code modifications
If you are moving older macros from a 32-bit AutoCAD environment to AutoCAD 2015 64-bit, your code might trigger compilation errors. The most common culprit is the handling of Windows API functions. Updating Declare Statements
Private Declare Function GetOpenFileName Lib "comdlg32.dll" Alias "GetOpenFileNameA" (pOpenfilename As OPENFILENAME) As Long
While the 64-bit module keeps legacy tools functional, Autodesk considers VBA a deprecated technology. Microsoft no longer actively develops the underlying VBA engine. For long-term automation stability, developers are encouraged to migrate complex workflows from VBA to , JavaScript , or the AutoCAD .NET API (C# or VB.NET) , which offer native 64-bit execution, better security, and superior performance.
