Something is missing in my masm32 v10,gdiplus_structs.inc ???
Perhaps if can have it ?

thanks ToutEnMasm, i attach the header & lib files here
this can be downloaded from the radasm website, but i cant remember exactly
the RectF structure in the gdiplus_structs.inc is probably not the same as in the cpp header file, so you may need to do a little change to it
thank you for your time and kind help!

There is something wrong here

Assembling: gdiptest.asm
;-----------------------------------------------
    local @r    :RectF
;-------------------------------------------------
RectF STRUCT
    Left REAL4 ?
    Top REAL4 ?
    Right REAL4 ?
    Bottom REAL4 ?
RectF ENDS
;-----------------------------------------------------
gdiptest.inc(72) : fstp @r.X :error A2006: undefined symbol : X
gdiptest.inc(75) : fstp @r.Y :error A2006: undefined symbol : Y
gdiptest.inc(78) : fstp @r.W:error A2006: undefined symbol : W
gdiptest.inc(81) : fstp @r.H :error A2006: undefined symbol : H

Sdk define of structure is

RectF STRUCT
      x REAL4 ?
      y REAL4 ?
      awidth REAL4 ?
      height REAL4 ?
RectF ends

NOT THE SAME !
Seems you have a patchwork of this structure

Here is a sample using the sdk rc7 translate and the libcmt,math functions atof.
all the gdiplus code is in OnPaint proc
