CHOOSECOLOR()函数怎么用

[smallcrocodile]

怎么没有人用过这个函数么？

用CColorDialog如何？

你说错了,CHOOSECOLOR是结构体,函数是ChooseColor();
ChooseColor函数的参数是一个CHOOSECOLOR结构体的指针.CHOOSECOLOR结构的定义如下:
typedef struct {
DWORD lStructSize;
HWND hwndOwner;
HWND hInstance;
COLORREF rgbResult;
COLORREF *lpCustColors;
DWORD Flags;
LPARAM lCustData;
LPCCHOOKPROC lpfnHook;
LPCTSTR lpTemplateName;
} CHOOSECOLOR, *LPCHOOSECOLOR;

调用ChooseColor函数,即会出现一个颜色选择对话框,你选中的颜色将放在你传进去的CHOOSECOLOR结构体里面返回.下面是一个例子:

CHOOSECOLOR cc; // common dialog box structure
static COLORREF acrCustClr[16]; // array of custom colors
HWND hwnd; // owner window
HBRUSH hbrush; // brush handle
static DWORD rgbCurrent; // initial color selection

// Initialize CHOOSECOLOR
ZeroMemory(&cc, sizeof(cc));
cc.lStructSize = sizeof(cc);
cc.hwndOwner = hwnd;
cc.lpCustColors = (LPDWORD) acrCustClr;
cc.rgbResult = rgbCurrent;
cc.Flags = CC_FULLOPEN | CC_RGBINIT;

if (ChooseColor(&cc)==TRUE) {
hbrush = CreateSolidBrush(cc.rgbResult);
rgbCurrent = cc.rgbResult;
}

上面说的对，要想更详细的资料，msdn中是有的，也有相应的例子
