VC界面/窗口的一些小技巧

- VC
1、刷新窗口
|
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
|
1 |
m_pMainWnd = &dlg; |
下面加入
|
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); |
4、设置Static Test为透明背景

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”); |
