If I remember correctly, Visual C++ 1.0 did not run on Windows 3.0, but Windows 3.1. (Windows 3.1 displaced Windows 3.0 almost immediately.) You could still create Windows 3.0 applications with it. The final version of Visual C++ 16-bit was 1.52c and I still have my CD-ROM for it in my closet (I had to support more than one 16-bit app through the 90s.)

Visual C++ 1.52c and Windows 3.1 are [typically] both available on eBay.

Hi,

LPRECT lprect;
CRect crect(lprect);

it throws exception as Access violation..
Please let me know how to convert LPRECT to Crect

LPRECT is a pointer to a RECT structure. In your case, you didn't initialize the pointer, so whe nthe constructor of CRect is trying the content of the pointer, this causes an access violation.

Use GetWindowText() to get the button's text, and then call GetTextExtent() (or related function) to get its width and heighth.

IWebBrowser2 problem

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

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.
