c preprocessor - How to define a define in C? -

-

is possible write #define defines #define?

for example:

#define fid_strs(x) #x #define fid_stre(x) fid_strs(x) #define fid_decl(n, v) static int fidn_##n = v;static const char *fids_##n = fid_stre(v)

but instead:

#define fid_decl2(n, v) #define fidn_##n v \                                fids_##n fid_stre(v)

fid_decl works fine creates 2 static variables. possible make fid_decl2 work , having define 2 defines?

no; preprocessing performed in single pass. if want or need more advanced behavior, consider using tool preprocess source, m4.

further, # in replacement list (at beginning of #define fidn... parsed # (stringize) operator: operand of operator must named macro parameter, define not.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
