VC界面/窗口的一些小技巧

目录表

1、刷新窗口

RedrawWindow(NULL, NULL,RDW_INVALIDATE | RDW_ERASE );

1	RedrawWindow(NULL, NULL,RDW_INVALIDATE \| RDW_ERASE );

2、设置对话框背景颜色

在InitInstance函数（CChatAPP类中）中的

m_pMainWnd = &dlg;

1	m_pMainWnd = &dlg;

下面加入

SetDialogBkColor(RGB(240,128,128),RGB(0,0,0));

1	SetDialogBkColor(RGB(240,128,128),RGB(0,0,0));

RGB(240,128,128)为背景颜色，RGB(0,0,0)为文本颜色

3、设置对话框背景图片

void CChatDlg::OnPaint()中
 
//CDialog::OnPaint();
CPaintDC   dc(this);  
CRect   rect;  
GetClientRect(&rect);  
CDC   dcMem;  
dcMem.CreateCompatibleDC(&dc);  
CBitmap   bmpBackground;  
bmpBackground.LoadBitmap(IDB_BITMAP1);  
//IDB_BITMAP是你自己的图对应的ID  
BITMAP   bitmap;  
bmpBackground.GetBitmap(&bitmap);  
CBitmap   *pbmpOld=dcMem.SelectObject(&bmpBackground);  
dc.StretchBlt(0,0,rect.Width(),rect.Height(),&dcMem,0,0,  
bitmap.bmWidth,bitmap.bmHeight,SRCCOPY);

void CChatDlg::OnPaint()中

//CDialog::OnPaint();

CPaintDC dc(this);

CRect rect;

GetClientRect(&rect);

CDC dcMem;

dcMem.CreateCompatibleDC(&dc);

CBitmap bmpBackground;

bmpBackground.LoadBitmap(IDB_BITMAP1);

//IDB_BITMAP是你自己的图对应的ID

BITMAP bitmap;

bmpBackground.GetBitmap(&bitmap);

CBitmap *pbmpOld=dcMem.SelectObject(&bmpBackground);

dc.StretchBlt(0,0,rect.Width(),rect.Height(),&dcMem,0,0,

bitmap.bmWidth,bitmap.bmHeight,SRCCOPY);

4、设置Static Test为透明背景

C

HBRUSH CChatDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) { HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor); // 改变所有的STATIC为透明，当然也可以将CTLCOLOR_STATIC改为CTLCOLOR_EDIT if(nCtlColor==CTLCOLOR_STATIC) { pDC->SetBkMode(TRANSPARENT); hbr=(HBRUSH)::GetStockObject(NULL_BRUSH); } // RedrawWindow(NULL, NULL,RDW_INVALIDATE | RDW_ERASE ); //改变单个的控件为透明 /* if(nCtlColor == CTLCOLOR_STATIC && pWnd->GetDlgCtrlID() == IDC_STATIC54) { // IDC_XXX_STATIC　为你想要设为透明的控件ＩＤ pDC->SetBkMode(TRANSPARENT); return (HBRUSH)GetStockObject(NULL_BRUSH); } / // TODO: Return a different brush if the default is not desired return hbr; }

HBRUSH CChatDlg::OnCtlColor(CDC pDC, CWnd* pWnd, UINT nCtlColor)
{
        HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

        // 改变所有的STATIC为透明，当然也可以将CTLCOLOR_STATIC改为CTLCOLOR_EDIT
        if(nCtlColor==CTLCOLOR_STATIC)
        {
                pDC->SetBkMode(TRANSPARENT);
                hbr=(HBRUSH)::GetStockObject(NULL_BRUSH);
       }
        // RedrawWindow(NULL, NULL,RDW_INVALIDATE | RDW_ERASE );

        //改变单个的控件为透明

        /*
        if(nCtlColor == CTLCOLOR_STATIC && pWnd->GetDlgCtrlID() == IDC_STATIC54)
       {
        // IDC_XXX_STATIC　为你想要设为透明的控件ＩＤ
        pDC->SetBkMode(TRANSPARENT);
        return (HBRUSH)GetStockObject(NULL_BRUSH);
        }
        */
        // TODO: Return a different brush if the default is not desired
        return hbr;
}

5、获取时间

CTime t=CTime::GetCurrentTime();
//CString time=t.Format(“%H:%M:%S”);
CString time=t.Format(“%Y-%m-%d %H:%M:%S”);

CTime t=CTime::GetCurrentTime();

//CString time=t.Format(“%H:%M:%S”);

CString time=t.Format(“%Y-%m-%d %H:%M:%S”);
