我的任务
分享(API)(SDK) 搞了一天还没搞定，静态文本和背景变色，，求大神，（完整代码）
SetTextColor和SetBkColor
在别的程序里都能变色，在这代码里就不行。。
case WM_CTLCOLORATSTIC 里用了也不行，不知什么原因造成的？？？

Edi控件的窗口style:
/*

*/
#define ES_LEFT 0x0000L
#define ES_CENTER 0x0001L
#define ES_RIGHT 0x0002L
#define ES_MULTILINE 0x0004L
#define ES_UPPERCASE 0x0008L
#define ES_LOWERCASE 0x0010L

#define ES_AUTOVSCROLL 0x0040L
#define ES_AUTOHSCROLL 0x0080L

#define ES_OEMCONVERT 0x0400L
#define ES_READONLY 0x0800L
#define ES_WANTRETURN 0x1000L
#if(WINVER >= 0x0400)
#define ES_NUMBER 0x2000L
#endif /* WINVER >= 0x0400 */GetWindowLong(hwnd, GWL_STYLE) & ES_READONLY != 0表示为只读！阿源是少年 2015-07-18

怎么看只读和非只读。[/quote]
只要你return (LRESULT)oldbrush;// 没初始化 返回一个非空画刷就有效果了，随便返回一个都行，如：
return (LRESULT)GetStockObject(BLACK_BRUSH);

不管什么颜色，但是在程序运行后，static控件的背景色还是系统默认的，btnface.

static控件应该在WM_CTLCOLORSTATIC消息里面设置，edit控件如果设置为只读，应该也是在WM_CTLCOLORSTATIC
消息里设置

case WM_CTLCOLORSTATIC:
SetTextColor((HDC)wParam,RGB(255,0,0));// 不分 哪个？nID = ::GetDlgCtrlID(hwnd);
SetBkColor((HDC)wParam,RGB(255,0,0));// 都是红的 ？
return (LRESULT)oldbrush;// 没初始化

[quote=引用 8 楼 shuo101 的回复:]
你去比较lParam就知道是哪个Static控件了，加一个switch(lParam){...}
quote]
case hst2:
CreateWindow返回的句柄，在 switch case 里显示不是表达式不是常量。
我用if 了，
非常感谢你。

LRESULT CALLBACK WindowProc(
HWND hwnd, // handle to window
UINT uMsg, // WM_CTLCOLORSTATIC
WPARAM wParam, // handle to DC (HDC)
LPARAM lParam // handle to static control (HWND)
);

static 的背景和文本颜色都变了。
我有6个static ，想把它们设置成6种颜色，可现在全是一种颜色。
case WM_CTLCOLORSTATIC:
SetTextColor(hdc,RGB(255,0,0));
SetBkColor((HDC)wParam,RGB(255,255,255));
hdc = GetDC(hst3);
SetTextColor(hdc,RGB(0,255,0));
ReleaseDC(hst3,hdc);
return (LRESULT)GetStockObject(WHITE_BRUSH);
我使用GetDC 获取，上面static 的句柄，然后选入，可为什么没效果。
不知道有什么方法吗？
