Compiler Warning - '_DMap.DrawBackBuffer' cannot be marshaled by the runtime marshaler

Mar 1, 2013 at 8:53 AM
Hi there,
I'm trying to run a project in C# with MapWinGIS. The project seems to work correctly, but I have several instances of the following warning:


Warning 1 Processing COM reference "MapWinGIS" from path "C:\dev\MapWinGIS\MapWinGIS.ocx". At least one of the arguments for '_DMap.DrawBackBuffer' cannot be marshaled by the runtime marshaler. Such arguments will therefore be passed as a pointer and may require unsafe code to manipulate.

A quick google search does not seem to return any results.

What does it mean, what am I doing wrong and how can I get rid of it?
Thanks,
Rik

Hi Rik,

You're not doing anything wrong. You can ignore these warnings.

Hi,

I get also those warnings, as I like to have no warning, still no way to change code avoid them ?

Thanks,
