更改控件的颜色

[yangsaibing]

请问：如何更改dialog上一个edit控件的背景颜色？

[ahphone]

是这个问题问得太多了
9. How do I change the background color of a dialog, or draw a picture in the background of my window? (top)

Handle the WM_ERASEBKGND message. For dialogs, do not handle WM_PAINT; WM_ERASEBKGND is the message designed for just this purpose.

Search MSDN for "WM_ERASEBKGND" and you'll find several pages on this topic.

处理WM_CTLCOLOR消息来改变

[prog_st]

HBRUSH CXXXDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
//设定EDIT的背景颜色
if(nCtlColor==CTLCOLOR_EDIT)
{
pDC->SetBkColor(RGB(0,255,255));
CBrush Brush(RGB(0,255,255));
hbr=(HBRUSH)(Brush.GetSafeHandle());
}
return hbr;
}

楼上的对

To Panda_w,prog_st , Hopping
采用WM_CTLCOLOR似乎只能初始化edit控件的颜色，如果想任意时候都可以改变
edit控件的颜色，该怎么办？

这个问题很难吗？怎么每人关注回答？

好象用CWnd::OnEraseBkGround()可以解决

[yangsaibing]

To shenyc:
OnEraseBKGroud在cwnd里是一个Protect 成员函数

对啊，我也想知道这个问题的答案。

学vc还是少搞界面花样
太累人了……

void SetDefaultActiveFgcolor(BOOL bRepaint=FALSE);
void SetActiveFgcolor(COLORREF crNew,BOOL bRepaint=false);
const COLORREF GetActiveFgcolor();
//设置光标滑过按钮时，按钮文本的颜色

void SetDefaultActiveBgcolor(BOOL bRepaint=FALSE);
void SetActiveBgcolor(COLORREF crNew,BOOL bRepaint=false);
const COLORREF GetActiveBgcolor();
//设置光标滑过按钮时，按钮的颜色
