I'am testing WinDev 12 Express with .Net assemblies
When I try to add a W-language eventhandler to a .Net event, compilation is OK but when I run the code, an error occurs on the add_Event call.
THe error is very strange because it suggests that WinDev runtime tries to load a .Net assembly with the name of the application directory.
Thanks for any suggestion.
Wilfried
The code:
dlg is object VCmdCallbackEventHandler dynamic = DotNetDelegate("VCmdCallback", "VivaUtils.VCmdCallbackEventHandler")
cb is object VCmdCallback dynamic = new VCmdCallback()
cb:add_Event(dlg)
The error
Error at line 52 of Click Days process.

Same problem here just that it happens only in the project configuration for a Windows Service, the normal client configuration does not throw the error and works fine. Even if the windows service is executed as an application the error persists.
There are no differences between the project configurations except of course one is "windows service" and the other one is "windows executable", same build folders, different install folders. |

One more observation:
- When the cleint configuration is generated a .dll library with the same name as the executable is also created. For the Windows Service executable this file is not created, if the .dll form the cleint isntallation is copied to the service installation and renamed to "executable_name".dll the assembly is found and loaded.
What is this dll sicne the actual assembly used by the project is a completly different dll always present in all instalations? |

Problem solved: In Visual Studio when creating a class library one should opt to create a .NET Framework Class Library - not .NET standard Class Library.
