VC雕虫小技集(四)

/develop/author/netauthor/he_zhidan/”>何志丹

1, 阅读常常要看此变量在那些地方值改变过

ctrl+f查找太麻烦

将此变量前加const

改变的地方 错

:namespace prefix = o ns = “urn:schemas–com::office” />

2, 看一个被那些函数.

方法:

1,状态下,view->de window->call Stack

2,class view 的快捷菜单中选择called by

3, 在状态栏的最左边显示时间

static UINT indicators[] =

{

ID_SEPARATOR,//我们增加的

ID_SEPARATOR,

ID_INDICATOR_CAPS,

ID_INDICATOR_NUM,

ID_INDICATOR_SCRL,

};

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)

{

…..  m_wndStatar.SetPaneInfo(1,ID_SEPARTOR,SBPS_NORMAL,60);

}

//菜单的响应函数

void CMainFrame::OnTest()

{

CTime t;

t = CTime::GetCurrentTime();

CString str = t.Format(“%H – %M  -%S”);

m_wndStatusBar.SetPaneText(0,str);

}

4,模拟鼠标

::SetCursorPos((int)ptMouse->x,(int)ptMouse->y);

::mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);

::mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);

::mouse_event(MOUSEEVENTF_LEFTDOWN,0,0,0,0);

::mouse_event(MOUSEEVENTF_LEFTUP,0,0,0,0);

5,什么是, DWORD

typedef unsigned short WORD

typedef unsigned long  DWORD

6,移动

CWnd * pWnd = GetDlgItem(IDC_BUTTON1);

CRect r;

pWnd->GetWindowRect(&r);

r.left +=50;

r.right += 50;

pWnd->MoveWindow(r);

7, 如何让对话框中的CEdit响应ENTER键回车

GetDlgItem(IDC_EDIT1)->SetWindowText(“111

22″);

右键属性

sytle -> Multiline选上

最好把want return 也选上

8,将c语言转化为

VC++ provs this feature.

Project->Settings…

C/C++ tab

Category: Choose Listing Files

Listing file type:

“Assembly with code”

9,如何获得进程所消耗的时间/p>

BOOL GetProcessTimes(

HANDLE hProcess,

LPFILETIME lpCreationTime,

LPFILETIME lpExitTime,

LPFILETIME lpKernelTime,

LPFILETIME lpUserTime

);

10,如何通过扩展名得到该扩展名所对应的图标/p>

SHGetFileInfo(path,

attr,

&i,

sizeof(SHFILEINFO),

SHGFI_USEFILEATTRIBUTES | SHGFI_ICON | SHGFI_TYPENAME);

如何在拉着对话框的边框改变大小时,让它成比例的变化.就像视频哪样

处理wm_sizing消息

void CTest 1Dlg::OnSizing(UINT fwSide, LPRECT pRect)

{

CDialog::OnSizing(fwSide, pRect);

if((fwSide==WMSZ_BOTTOM) || (fwSide==WMSZ_TOP))

pRect->right=pRect->left+(pRect->bottom-pRect->top)*2;

else

pRect->bottom=pRect->top+(pRect->right-pRect->left)*0.5;

}
