MFC下怎样获取一个txt文件的当前路径

MFC下怎样获取一个txt文件的当前路径,第1张

CFileDialog::GetFolderPath ,这个是顺着CFileDialog思路的。

GetCurrentDirectory,可以获取当前的路径。如果你打开txt用的只是文件名称,没有路径的话,那使用的路径就是GetCurrentDirectory获取的路径。

LPTSTR lpFilename, // path buffer 得到的文件名。

DWORD nSize // size of buffer 一般MAX_PATH就可以了

);

给你一个通用的步骤吧,看不懂我再详细说(你需要的步骤是1-2-32):

1CMDIFrameWnd pFrame = (CMDIFrameWnd)AfxGetApp()->m_pMainWnd;

2CMDIChildWnd pChild = (CMDIChildWnd ) pFrame->GetActiveFrame();

3

31获得视类:CMyView pView = (CMyView ) pChild->GetActiveView();

32获得文档类:CDocument pDocument=pChild -> GetActiveDocument();

给ComboBox绑定一个变量,如下,不绑定也可以(会比较烦)

 CString strCBText;

 m_comboxGetLBText(m_comboxGetCurSel(), strCBText);

 或

 ((CComboBox)GetDlgItem(IDC_COMBO1))->GetLBText(((CComboBox)GetDlgItem(IDC_COMBO1))->GetCurSel(), strCBText);

if(vResultboolVal!=0)

{

long x, y;

CRange Th_range; \\加入新的CRange对象

Th_rangeAttachDispatch(rangeget_MergeArea(),true); \\获取合并单元格区域

m_ecRangeAttachDispatch(Th_rangeget_Rows(),true); \\Th_range内获取行

x=m_ecRangeget_Count();

m_ecRangeAttachDispatch(Th_rangeget_Columns(),true);\\Th_range内获取列

y=m_ecRangeget_Count();

if(col_row)

return y;

else return x;

}

CMDIFrameWnd pFrame = (CMDIFrameWnd)AfxGetApp()-> m_pMainWnd;

// 获取活动的子框架

CMDIChildWnd pChild = (CMDIChildWnd ) pFrame-> GetActiveFrame();

// 或者 CMDIChildWnd pChild = pFrame-> MDIGetActive();

// 获取当前活动的视图指针

CMyView pView = (CMyView ) pChild-> GetActiveView();

CmyDocument pDoc =(CmyDocument) pView-> GetDocumnet()
