pcsoft.us.windevCopyright 2026, PC SOFT2 May 2019 11:09:35 Z13 May 2010 23:27:50 ZI'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.
