Hi Guys,

I want to write an function which will accept an file name(along with complete path), append an prefix to it (say Admin to the file name from c:\Sample\sam.txt to c:\Sample\Adminsam.txt). I have written an function via character array manipulation and given below.

<br />
#define ADMIN_PREFIX			_T("Admin")<br />
static void RenameToAdminFile(LPCTSTR szFilePath/*in*/, LPTSTR szAdminFilePath/*out*/)<br />
{<br />
    TCHAR szTempFilePath[MAX_PATH] = _T(""), *pCh;<br />
	TCHAR szFileName[MAX_PATH] = _T("");<br />
	_tcscpy(szTempFilePath, szFilePath);<br />
	bool bValidPath = false;<br />
	<br />
    if (pCh = _tcsrchr( szTempFilePath, _T('\\')))<br />
    {<br />
        pCh++; // Keep trailing "\\"<br />
		_tcscpy(szFileName, pCh);<br />
        *pCh = _T('\0');<br />
		bValidPath = true;<br />
    }<br />
    else<br />
    {<br />
        if (pCh = _tcsrchr( szTempFilePath, _T(':')))<br />
        {<br />
            pCh++; // Keep trailing ":"<br />
			_tcscpy(szFileName, pCh);<br />
            *pCh = _T('\0');<br />
            _tcscat(szTempFilePath, _T("\\"));<br />
			bValidPath = true;<br />
        }<br />
        else<br />
        {<br />
            *szTempFilePath=_T('\0');<br />
        }<br />
    }<br />
	if(bValidPath)<br />
	{<br />
		TCHAR szTempAdminFileName[MAX_PATH] = ADMIN_PREFIX;<br />
		_tcscat(szTempAdminFileName, szFileName);<br />
		_tcscat(szTempFilePath, szTempAdminFileName);<br />
	}<br />
	_tcscpy(szAdminFilePath, szTempFilePath);<br />
	return;<br />
}

Are there any STL API's (Not CString methods)that I could use to achieve the same? An code snippet will be of great help.

Use _tsplitpath to separate the drive letter, folder name, file name and extension into separate variables.
Now you can change the filename by attaching "Admin" into another buffer using _tcscpy_s and _tcscat_s and then stitch the full path back together using _stprintf_s.

Thanks for the Info.

Yes. You can use _wsplitpath to split the file path into Drive letters, directory, filename, and file extension and now you can do any manipulation with any of the individual members like appending the file name with an string.
Now you can put individual file info togather using the api _makepath.

std::string RenameToAdminFile(std::string const& file)
{
   std::string::size_type lastSep = file.find_last_of('\\');
   if (lastSep != std::string::npos)
   {
      return file.substr(0, lastSep+1) + "Admin" + file.substr(lastSep+1);
   }
   else
   {
      return "Admin" + file;
   }
}

?

Hack-amungous, of course, as it assumes various things. As I suggested to someone else today - Boost.FileSystem[^] is a nice (and cross-platform) path manipulation library.

Hi,
the return code is S_OK, and then i try with this very simple code, and the result is the same, nothing is shown! Frown | :(

CString str_html = L"<html><head<meta http-equiv=\"Content-Type\" content=\"text/html; charset=ISO-8859-1\">Hello worls!</body></html>";
HRESULT hres;
	
if(S_OK != (hres = m_cBrowserDetails.SetDocumentHTML(str_html)))
	Sleep(10); // i have here a breakpoint

Then i try with COM and SAVEARRAY, but is the same result!

I'm just guess here, but you could try and switch off edit mode using CHtmlEditCtrlBase::SetDesignMode[^]

Hi,
im using
CDC* pObject;
Crect ButtonRect;
Buttonrect is the rect of the total button....
pObject->DrawText(_T("hi"), ButtonRect, DT_END_ELLIPSIS);

RectText is the rect of the text inside button...
and im using pObject->DrawFocusRect(Recttext);

but the issue is focusrect is drawn along the button edges instead of the text edges...
Please try to help....

RectText is the client rect of the button
CRect rCalc(RectText);

UINT nVAlign = (nAlign & (DT_VCENTER | DT_TOP | DT_BOTTOM));
nAlign &= ~(DT_VCENTER | DT_TOP | DT_BOTTOM);

int nHeight = pDC->DrawText(sText, rCalc, nAlign | DT_CALCRECT);

if (RectText.Height() > nHeight)
{
if (nVAlign & DT_VCENTER)
RectText.DeflateRect(0, (RectText.Height() - nHeight) / 2);

else if (nVAlign & DT_BOTTOM)
RectText.top = RectText.bottom - nHeight;

else // top
RectText.bottom = RectText.top + nHeight;
}

if (RectText.Width() > rCalc.Width())
{
if (nAlign & DT_CENTER)
RectText.DeflateRect((rText.Width() - rCalc.Width()) / 2, 0);

else if (nAlign & DT_RIGHT)
RectText.left = RectText.right - rCalc.Width();

else // left
RectText.right = RectText.left + rCalc.Width();
}

and im using and im using pObject->DrawFocusRect((LPRECT)Recttext);

but it doesn"t draws the focus rect just around the text but it draws a rect which is less than the boundaries of the text....

The DT_CALCRECT cannot be used with the DT_TABSTOP style. So please check whether your nAlign has DT_TABSTOP flag.

Optionaly you can use the GetTextExtent() function to find the width and height of the text.

Hi,

In my application I need to control current the view of the folder opened in windows explorer.

User will start my application....He will also open a folder in the windows explorer. When he clicks a button in my application the view of the folder will change.(View means list,thumbnails,icon)

Please let me know where should i start?

Regards and thanx,
J

Why not host the Explorer folder view in your own application[^]?

I may also need to implement keyboard shortcuts to the currently opened folder in the windows explorer to change views, so it cannot be hosted in my app.

Well, see, the trouble is that the concept of there being a single current folder open in Explorer (which you say is what you want to manipulate) is invalid. There may be any number of folders open in Explorer windows concurrently.

Try taking a step back and telling us what you're actually trying to accomplish with this - there may be ways other than the obvious, brute force method...

C C++ Eclipse plugins

hi Guys,
I just shifted from Visual Studio to Eclipse for C,C++ programming.

I downloaded the newest version Galileo and C,C++ is working fine.

However are there plugins for Eclipse that you would recommend?

Like Flowchart designers or Code re factoring tools, you know some stuff that I should be aware of.

Thanks in advance,

Cheers

Last time I tried to use Eclipse (for C++ development) it was painly slow and (IMHO) deadly counter-intuitive. I know it is just a personal feeling (and I didn't deelve into), but, anyway...Good luck!
