if(dlg.DoModal() == IDOK)
{
MemDC.Attach(dlg.GetPrinterDC());//把打印設備環境附加到DC對象

di.cbSize = sizeof(DOCINFO);
di.lpszDocName = "圖形報告";
di.lpszOutput = NULL;
di.lpszDatatype = NULL;
di.fwType = 0;
MemDC.StartDoc(&di); //通知打印機驅動程序執行一新的打印任務
MemDC.StartPage();//通知打印機驅動程序打印新頁
MemDC.SetMapMode(MM_ANISOTROPIC);//(MM_HIENGLISH);//設置當前影射模式為：單位0.001英寸
CSize size = CSize(800, 560);
MemDC.SetWindowExt(size);
//確定窗口大小
//得到實際設備每邏輯英寸的象素數量
int xLogPixPerInch = MemDC.GetDeviceCaps(LOGPIXELSX);
int yLogPixPerInch = MemDC.GetDeviceCaps(LOGPIXELSY);
//得到設備坐標和邏輯坐標的比例
long xExt = (long)size.cx * xLogPixPerInch/96 ;
long yExt = (long)size.cy * yLogPixPerInch/96 ;
MemDC.SetViewportExt((int)xExt, (int)yExt);
MemDC.TextOut(350,20,"測試報告");
//在這里加入你想要進行的繪制及文字輸出

//
//
//
//
//

//
MemDC.EndPage(); //通知打印機驅動程序頁結束
MemDC.EndDoc();//通知打印機驅動程序打印完畢
DeleteDC(MemDC.Detach());

4.Re:如何改變Edit中的字體顏色 [所有相關帖子]
如何改變對話框內控件的字體?
你有沒有感到Edit,Static....控件的字體太單調,沒什么新新樣?下面的內容,給你一個解答.
[解決方法]
簡單的步驟:在Windows中,每個窗體都有自己的字體.要改變其字體首先要CFont::CreateFont創建一個字體,然后用CWnd::SetFont選擇此字體,賦給控件.但很多人可能會因為CreateFont的參數之多,望而卻步.下面我介紹一下參數.
函數原型:
BOOL CreateFont( int nHeight, int nWidth, int nEscapement, int nOrientation, int nWeight, BYTE bItalic, BYTE bUnderline, BYTE cStrikeOut, BYTE nCharSet, BYTE nOutPrecision, BYTE nClipPrecision, BYTE nQuality, BYTE nPitchAndFamily, LPCTSTR lpszFacename );
參數說明:
nHeight :字體高度.>0:字體的高度值;=0:字體采用缺省直.<0:此值的絕對值為高度.
nWidth :字體寬度.
nEscapement :文本行的傾斜度.
nOrientation :字符基線的傾斜度.
nWeight :字體的粗細.如下:
.FW_DONTCARE
.FW_THIN
.FW_EXTRALIGHT
.....
bItalic :字體是否為斜體
bUnderline :字體是否帶下劃線
cStrikeOut :字體是否帶刪除線
nCharSet :字體的字符集
.ANSI_CHARSET
.DEFAULT_CHARSET
.SYMBOL_CHARSET.....
nOutPrecision :字符的輸出精度
nClipPrecision :字符裁剪的精度
nQuality :字符的輸出質量
nPitchAndFamily :字符間距和字體族(低位說明間距,高位說明字符族)
lpszFacename :字體名稱
[程序實現]
假設你已有了名為My的對話框工程.并有一個ID=IDC_EDIT1的Edit控件.
class CMyDlg : public CDialog
{
public:
CFont m_Font;
........
};
BOOL CTMyDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// TODO: Add extra initialization here
//CFont m_Font;
m_Font.CreateFont(-11,0,0,0,100,FALSE,FALSE,0,ANSI_CHARSET,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,FF_SWISS,"Arial");
CEdit *m_Edit=(CEdit *)GetDlgItem(IDC_EDIT1);
m_Edit->SetFont(&m_Font,FALSE);
return TRUE; // return TRUE unless you set the focus to a control
}
小小說明:在OnInitDialog()中的//CFont m_Font;前的"http://"號去掉,將類聲明中的CFont m_Font;去掉會是什么結果?請自己試試.
改變Edit字體顏色！ [所有相關帖子]
HBRUSH CButtonDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
// TODO: Change any attributes of the DC here
if(nCtlColor == CTLCOLOR_EDIT)
{
if(pWnd->GetDlgCtrlID()== IDC_EDIT1)
{
pDC->SetTextColor(RGB(255,255,0));
pDC->SetBkColor(RGB(251, 247, 200));
pDC->SetBkMode(TRANSPARENT);
return (HBRUSH) m_brush.GetSafeHandle();
}
}
// TODO: Return a different brush if the default is not desired
return hbr;
}
5 如何注冊控件?
這是一個很常見的問題,最簡單用winodws自帶的regsvr32或其它工具等,其原理是利用控件的regsiterserver函數與unregsiterserver來實現注冊與取消注冊,以下是代碼實現注冊:
dword registerserver( char* szpath )
{
hinstance hinstance = ::loadlibrary( szpath );
if ( 0 == hinstance )
{
return ::getlasterror();
}
typedef void (far pascal *regserver)(void);
regserver regserver = (regserver) ::getprocaddress( hinstance, _t( "dllregisterserver" ));
if ( 0 == regserver )
{
::freelibrary( hinstance );
return ::getlasterror();
}
regserver();
::freelibrary( hinstance );
}
6模擬點擊按鈕
::SendMessage(GetParent()->GetSafeHwnd(), WM_COMMAND, (WPARAM)MAKELONG(IDOK, BN_CLICKED), (LPARAM)GetParent()->GetDlgItem(IDOK)->GetSafeHwnd());
7枚舉進程
void GetProcessID(LPTSTR pszProcessName, DWORD& th32ProcessID)
{
HANDLE hSnapshot = NULL;
__try
{
hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if (INVALID_HANDLE_VALUE == hSnapshot)
{
__leave;
}
PROCESSENTRY32 pe;
ZeroMemory(&pe, sizeof(PROCESSENTRY32));
pe.dwSize = sizeof(PROCESSENTRY32);
BOOL bProcess = Process32First(hSnapshot, &pe);
while (bProcess)
{
if (pe.szExeFile == StrStrI(pe.szExeFile, pszProcessName))
{
th32ProcessID = pe.th32ProcessID;
break;
}
bProcess = Process32Next(hSnapshot, &pe);
}
if (!bProcess)
{
__leave;
}
}
__finally
{
if (INVALID_HANDLE_VALUE != hSnapshot)
{
CloseHandle(hSnapshot);
}
}
}
