1. In my code whenever I set optimization level 3 with time, i got warning:
"warning: C4017W: __x__1 may be used before being set"
2. In the file in which this error, I have included "math.h"
3. When I remove "math.h", warning gets removed.
4. Tool Version Numbers:

I had the same problem
typedef struct POINT_XY { /* "POINT_XY" structure type */ INT16 x; /* X coordinate */ INT16 y; /* Y coordinate */ }POINT_XY ;
void On_CliquerUnAngle( POINT_XY pt ) { POINT_XY ptHere ; INT16 MemoXOrigin_LAlpha_Here , MemoYOrigin_LAlpha_Here ;
MemoXOrigin_LAlpha_Here = GetOriginX ();
MemoYOrigin_LAlpha_Here = GetOriginY ();
SetOrigin(MemoXOrigin_LAlpha, MemoYOrigin_LAlpha);
ptHere.x = XScreenToImage(pt.x); ptHere.y = YScreenToImage(pt.y); if (CliquerUnAngle( ptHere , ListSauvePosAngle_L_Alpha )) { SetOrigin(MemoXOrigin_LAlpha_Here, MemoYOrigin_LAlpha_Here); CallAfficheLaPieceCall(); } else { SetOrigin(MemoXOrigin_LAlpha_Here, MemoYOrigin_LAlpha_Here); } }
..\..\..\General\MAIN\Dessin2D\Pli_2D\Xp2dP2dP.cpp(4206): warning: C4017W: ptHere may be used before being set
>> I did
ptHere.x = XScreenToImage(pt.x); ptHere.y = YScreenToImage(pt.y);
thank
This would be a lot clearer if you followed the simple posting tips with regards to placing source code in a post, and you identified which line the error falls, as we're missing 4200+ of them.
