Hello,
I have a quick question regarding CFileDialog..

I have a SDI type app with a "Settings" dialog box.. I allow the user to click a browse button with in the settings dialog box and select a .wav file as a sound/alert setting (using CFileDialog). The problem is that when the user selects the .wav file my current working directory changes to the path of the .wav file, so, if I do a "save" behind the scenes it saves my document to the same directory as the wav file not the directory of my .exe.

How can I prevent the current working directory (my .exe dir) from being set to the CFileDialog directory??

Thanks,
Rob

How can I get the directory that the .exe sits in on startup?? GetCurrentDirectory will not work. Is there another way?

Give this a shot. Big Grin | :-D

// determine the directory and remember it
	_TCHAR drive[_MAX_DRIVE];
	_TCHAR dir[_MAX_DIR];
	_TCHAR fname[_MAX_FNAME];
	_TCHAR ext[_MAX_EXT];
	_TCHAR path[_MAX_PATH];
	::GetModuleFileName(NULL, path, _MAX_PATH);
	_tsplitpath(path, drive, dir, fname, ext);

	CString sFolder = CString(drive) + dir;

Thanks!

i know, i have posted this question some days ago ...
but this example :

CHARRANGE cr;
cr.cpMax = LONG_MAX;
cr.cpMin = LONG_MAX;
richedit.SetSel( cr ); // move selection to the bottom
richedit.ReplaceSel( (LPCSTR)string ); // insert your text

// force the rich edit to scroll to the bottom
richedit.SendMessage( SB_BOTTOM, NULL, NULL );

doesn't work correctly. (for richedit)

Maybe anybody else knows, how ara many clients prints channel text (mIRC, Client, etc... )

it would be better give some examples (full sources of small exampl-programs) ...

thanks

CListCtrl adds blank items

5-Oct-02 12:25

You could try this

// strMessage is the text you want to send to the edit control
CString strRecvd;
m_cRichEdit.GetWindowText(strRecvd);
	
if(strRecvd.IsEmpty())
     m_wndMonitor.SetWindowText(strMessage);
else if(!strRecvd.Right(1).CompareNoCase("\n"))
    m_cRichEdit.SetWindowText(strRecvd + strMessage);	
else
     m_cRichEdit.SetWindowText(strRecvd +"\n"+ strMessage );
	
// Scroll the line down
m_cRichEdit.SetSel(-1, -1);
m_cRichEdit.SendMessage(EM_SCROLLCARET);

Hope it helps

Hello,

I'm trying to implement a CListCtrl that will add items from a database but for some reason (that I can't figure out) the CListCtrl is adding only blank strings. My code is as follows:

for (i = res.begin (); i != res.end (); i++) {
    dateinfo = *i;
    lvi.mask = LVIF_TEXT;
    lvi.iItem = j++;
    lvi.iSubItem = 0;
    lvi.pszText = (LPTSTR)(LPCTSTR) dateinfo["created"].c_str ();
    m_listDate.InsertItem (&lvi);
}

I've checked the lvi.pszText attribute of the LV_ITEM struct and it contains the string right before the call to CListCrtl.InsertItem.

Any ideas as to why blank strings are being added? Any help is much appreciated.

Thanks

A quick addition to the stuff above. As you probably guessed I'm using the CListCtrl in report mode but if I use it in list mode and just use CListCtrl::InsertItem (int nItem, LPCTSTR lpszItem) the text inserts fine but it isn't one long list which is what I need. Just thought I'd let you all know that. As well if anyone knows a way to make a CListCtrl in list mode just have one long list (instead of scrolling sideways) I could just do that instead.

Thanks again.

Did you insert a column into the list?

ARGH! Nope, I didn't even think of it. If I set the style not to have column headers will I still need to add the column? I only ask because I did set it to have no column headers and it still wouldn't work.

Thanks Again!

Yes, without columns there's no place for the list to display any data.

hello!

i want to read a .txt file after i clicked a button in a dialogbased mfc-program.
can somebody give me an example code or links or tipps?

somebody gave me a short overview (here in this forum), but i make mistakes and don´t understand everything.

The overview:
create an ifstream object
call open
set file pointer to end using seekg
call tellg to get the number of bytes in the file
allocate that number of chars
set file pointer to beginning using seekg
call read
call close

Thanks
Sunny

If you're using MFC then it is easier to use CFile or CStdioFile to read the contents of a txt file.

CFile file("C:\\foo.txt", CFile::modeRead);

file.Read(...)

Make sure to check for any errors.

thanks for your reply.

i tried your idea, but what must i write behind the file.read(..??..).

i read inside the help: read(void* lpBuf, UINT nCount).

i tried several things, like file.read(*buffer, 50), file.read(buffer, 50), etc...
but each time it was wrong.
where is my error?

I do it like this..

CString strBuff;
CFile file;
if(file.Open(_T("anyfile.dat"),CFile::modeRead))
{
	//Declare a large buffer for reading the text
	char cBuf[2048];
	UINT uBytesRead;
					
	//Continue reading until no more data is read
	while(uBytesRead = file.Read(cBuf, sizeof(cBuf)-1))
	{
		//Null terminate after the last charcter
		cBuf[uBytesRead] = NULL;
		
		//add the buffer to the mapped CString
		strBuff += CString(cBuf);
	}
	// Make sure you close the file after reading		
	file.Close();

// Now do something with the string strBuff
...
}
else
{
// the file couldnt be opened get errors here
}

Hope it helps
