Hi all,

I have CWebBrowser wrapper for IWebBrowser2 class. i use it to run flash and static images.

Problem is sometimes my application crashes because of certain flash that is running inside the web browser. (i can not tell which flash causes this).

i have several computers which has visual studio debugger, so after this crash i see the debugger dialog...
someone has suggested the problem is permission...but i am not sure...

is there a way to catch or neutralizer the crash via IWebBrowser2?

thanks for any thoughts or solutions

i saw something on MSDN:

http://support.microsoft.com/kb/317024[^]

but the question is if the page creates iframe within iframe within iframe (which is out of my control) and i place on error at the top of the html (not the inner iframe) will it be caught?

String manipulation.

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[^]

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.

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.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
