I got my initial code working on the C DLL and it's creating snapshot sets as I want. I am now having a problem with a function to query ALL the snapshots.
This value can be sent to SetContext() In [39]: alphavsslib.VssSnapshotContext.All Out[39]: 4294967295 4294967295 = 0xFFFFFFFF A sample of the call is here: https://github.com/alphaleonis/AlphaVSS-Samples/blob/8482e83dd13cb8467860e8be199d265963aa6ab8/src/SnapshotQuery/Program.cs # this is the declaration of SetContext virtual void SetContext(VssSnapshotContext context); This is the declaration for All: VssSnapshotContext.All = 0xFFFFFFFF https://github.com/alphaleonis/AlphaVSS/blob/13462e657f7993da5c80f835d219bbe82079ce75/src/AlphaVSS.Common/Enumerations/VssSnapshotContext.cs#L58 However, this line results in a Type error In [40]: ctx = cmp.SetContext(alphavsslib.VssSnapshotContext.All) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) Input In [40], in <cell line: 1>() ----> 1 ctx = cmp.SetContext(alphavsslib.VssSnapshotContext.All) TypeError: No method matches given arguments for SetContext: (<class 'int'>) I've tried converting the value using: ctx = cmp.SetContext(System.Convert.ToUInt32(alphavsslib.VssSnapshotContext.All)) *And* ctx = cmp.SetContext(ctypes.c_uint32(alphavsslib.VssSnapshotContext.All).value) but the same error occurs I can get the function to succeed (albeit it doesn't show me what I want) with this: cmp.SetContext(ctypes.c_int32(alphavsslib.VssSnapshotContext.All).value) ... because ctypes.c_int32(alphavsslib.VssSnapshotContext.All).value = -1 I believe it's possible that this could be related to the link below but I can't be sure because I am not a C developer and I can't determine how this was fix from the notes in the link. Granted, the author is on CentOS, and I'm on Windows... but the backstory behind the issue sounds like it's related. https://github.com/pythonnet/pythonnet/issues/950 I'm currently running on pythonnet 2.5.2 and Python 3.9.13 (tags/v3.9.13:6de2ca5, May 17 2022, 16:36:42) [MSC v.1929 64 bit (AMD64)] on win32 Any thoughts or suggestions would be greatly appreciated.
