1. Could you explain what are you trying to achieve using such type of very dangerous castings?

   //try cast/convert original var
   (int)var += 30003;
   }

   
   The problem with this "casting" is the origin of the parameter passed to is short integer (the low WORD in Win32 environment).
   But you are then trying to interpret it (somehow) as int causing to take into account the high WORD which contain garbage!
   So what do you expect from the next manipulations with this garbage?

int tmp = (short int)var;

is this a valid cast short to int ?

C++

int tmp = (short int)var;

Looking through the Messages list in Class Wizard, I don't see anything that seems related to this. The control already has OnMouseWheel and OnVScroll handlers, and they work fine.

echo Debugging Path: $(TargetPath)
echo Executable Path: $(OutDir)$(TargetName)$(TargetExt)
