| Time Class in Managed C++? (2 replies) |
| microsoft.public.dotnet.languages.vc |
| Is there a "managed C " wrapper class for time variables? I am writing some managed wrapper classes for a series of exportable classes in a DLL written under VC 6. One of the methods of a class in the DLL returns a CTime object, and I would like the managed class to return the ..NET analogue. What is this? Thanks, Mark PS. So far I find "managed C " to be something of a misnomer managed it may be,... |

| LoadLibrary generates MessageBox when failing to loadlibrary in Managed C++ (8 replies) |
| microsoft.public.dotnet.languages.vc |
| I have a Managed C DLL that calls LoadLibrary on a VC6.0 DLL. The DLL exists and normally loads, but the DLL is statically linked to another DLL. Just as a test, I removed the statically linked DLL from the path so it wouldn't be able to load. I put error handling in the Managed C DLL to check the result of LoadLibrary. All the code works fine except that the call to LoadLibrary pops up a dialog s... |
