Problems with drawing icons using drawicon

Problems with drawing icons using drawicon

When I used drawicon to draw an icon, I found that the drawn icon was too large. I originally wanted to draw a 16x16 icon, but the drawn icon was obviously stretched.
It turns out that the size of the icons drawn by drawicon is the size of getsystemmetrics (sm_cxicon) and getsystemmetrics (sm_cyicon). To draw a custom size icon, you cannot call drawicon, you can call this function:
Bool drawiconex (
HDC,
Int xleft,
Int ytop,
Hicon,
Int cxwidth,
Int cywidth,
Uint istepifanicur,
Hbrush hbrflickerfreedraw,
Uint diflags
);
For example: drawiconex (pdcmem-> m_hdc, 0, 0, hicon, 16, 16, 0, null, di_normal); draws a 16x16 icon
