用VC写了个颜色选取框，仿Office风格用VC写了个颜色选取框，仿Office风格，没用MFC什么的框架，调用很简单指定显示位置POINT和默认颜色就可以，如：
POINT pt；
pt.x = 100； pt.y = 100；
CColorPicker *clrpk = new CColorPicker（&pt， HexClr（0xFF0000））；
效果图：
C++的颜色拾取框
代码：
ColorPicker.h
#define HexClr(rgb) ((DWORD)(rgb>>16)|(rgb&0xFF00)|((rgb&0xFF)<<16))
#define COLORPICKERWINNAME "ColorPickerWin"
#define WM_COLORSELECTED WM_USER+2938
static DWORD ColorMap[5][8] =
{
{ HexClr(0x000000), HexClr(0x993300), HexClr(0x333300), HexClr(0x003300), HexClr(0x003366), HexClr(0x000080), HexClr(0x333399), HexClr(0x333333)},
{ HexClr(0x800000), HexClr(0xFF6600), HexClr(0x808000), HexClr(0x008000), HexClr(0x008080), HexClr(0x0000FF), HexClr(0x666699), HexClr(0x808080)},
