如何改变程序的界面--急

Question

我在网上下了个视频,发现了个改变界面的程序,我按照它的做了,界面也出来了,可是发现了一个问题,就是将开发工具最小化时,界面又恢复到了原来的样子, 代码如下:
void CMyDlg::DrawDialog(UINT Flags)
{
    m_FrameHeight   = GetSystemMetrics(SM_CYFIXEDFRAME);
m_BorderHeight  = GetSystemMetrics(SM_CYBORDER);
m_FrameWidth    = GetSystemMetrics(SM_CXFIXEDFRAME);
m_BorderWidth   = GetSystemMetrics(SM_CXBORDER);
m_CaptionHeight = GetSystemMetrics(SM_CYCAPTION); CRect Clientrect;
GetClientRect(Clientrect);
CRect WinRC,FactRC;
GetWindowRect(WinRC);
FactRC.CopyRect(CRect(0,0,WinRC.Width(),WinRC.Height()));
//获取窗口设备上下文

}void CMyDlg::DrawCaption()
{
    if(!m_Caption.IsEmpty())
{

pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(m_CapitonColor);
pDC->SetTextAlign(TA_CENTER);
CRect rect;
GetClientRect(rect);
pDC->SelectObject(&m_CaptionFont);
pDC->TextOut(rect.Width()/2, m_CaptionHeight/3 ,m_Caption);
ReleaseDC(pDC);
}
}
在onpaint()函数中调用上面的drawdialog函数,出现的问题就是当把另一个程序如word等最小化时,我写的这个程序外观就自动变成了windows的样式,而我做的程序不是windows的样式,标题栏等我用的是图片,可最小化其它程序后,标题栏的图片就不见了,又成蓝色的了

Answer 1

这两个自绘的函数都要在Onpaint中调用

Answer 2

void CMyDlg::OnPaint() 
{
if (IsIconic())
{
CPaintDC dc(this); // device context for painting SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0); // Center icon in client rectangle
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2; // Draw the icon
dc.DrawIcon(x, y, m_hIcon);
}
else
{
CDialog::OnPaint();
}
DrawDialog(FALL);
m_IsDrawForm = TRUE;
}
