good morning,
I am trying to go from mapwingis 4.9.3.4 to mapwingis 5.3.0.0 to work with visual studio 2019.
I have uninstalled version 4.9, rebooted and installed the 32 bit version of mapwingis 5.3.0.0. When adding the .Com component “MapControl” to the project there is no error, the problem is that it needs the references to AxInterop.MapWinGis and Interop.MapWinGis (I have both in version 4.9). Where can I get the updated versions to 5.3.0.0? The problem I’m having is that when performing a DrawPoint I get an error System.Runtime.InteropServices.COMException: Non-optional parameter. (Exception from HRESULT: 0x8002000F (DISP_E_PARAMNOTOPTIONAL))
The line of code is the following:
axMap1.DrawPoint(-87.093048, 70.559164, 5, 0xff0000)
I hope you can help me. Thank you.
