怎样把 STATIC 静态文本的背景改变颜色，解决了我会把分加满！
我看论坛上有这个东西，我VC水平实在不行，根本不会用
HBRUSH CAboutDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
UINT id=pWnd->GetDlgCtrlID();
if (id==IDC_STATIC1) //改变 id为IDC_EMAIL static 的颜色
{
pDC->SetTextColor(RGB(0,0,255));
}
return hbr;
}
我就想做三个按钮，点击第一个，静态框变红色；点击第二个，静态框变绿色；点第三个，静态框变红黄色，我怎么来使用上面的函数，请大虾给细节指导！

不要用这个函数，直接
SetBkColorTop

用一个变量来记录当前的状态Top

设置一个变量，在按钮响应函数里分别赋值，在OnCtlColor里根据不同变量值返回不同颜色，按下按钮时刷新窗口就有了Top

改变背景不用这么复杂啊，你写的那个是改变字的颜色的吧～～～Top

我怎么获取我静态文本的句柄？用GetDC吗？怎么用的，给写个小实例吧！Top

CWnd *pWnd;
pWnd=(CWnd*)GetDlgItem(IDC_STATIC1);
CDC *dc=pWnd->GetDC();Top

如果实现楼主的问题我想不能用OnCtlColor这个方法，这个方法虽然能够改变背景颜色，但是不能够动态改变，楼上已经有了很多解决方法，也可以重载一个CStatic类，可以重写很多有用的操作，代码如下-------------->

3.用法(假如m_stInfo是CLabel)
m_stInfo
.SetFontName("宋体")
.SetFontSize(12)
.SetTextColor(RGB(0,255,0))
.SetFontUnderline(FALSE)
.SetBkColor(RGB(0,0,0))
.SetFontItalic(FALSE)
.SetFontBold(FALSE)
.SetBorder(FALSE)
.SetSunken(TRUE);

去网上搜索一下有好多（CLabel.h,CLabel.cpp）添加到你的项目中。然后给你的静态文本框的ID值不要用默认的，然后就可以给他添控制变量了（CLabel型的控制变量），
如你的控制变量为m_LoadLab_Con
m_LoadLab_Con.SetFontSize(40)
.SetBkColor(RGB(0,0,0))
.SetFontName("黑体")
.SetTextColor(RGB(121,251,220));
上面的你就可以看懂了吧，你的程序可以设置标志位来改变静态文本框的颜色了。Top
