Your post is confusing

There are no functions that are managed code. Perhaps you can post the code and link to the MSDN documentation[^] for what you are using. That way we can be clear what you are doing.

Never mind. I meant CLI integration with .net etc. In any event I ripped out the CRT requirement I imposed on myself by using MS's .net crypto services, in so doing nearly halfed my executable size and replaced the functionality with some native C++. In the end the problem wasn't what I thought. I tracked it down to one uninitialized variable. For whatever reason in the IDE it ran fine but outside it didn't.

Hi,

I am using CDateTimeCtrl to display current time, but do not want to display the seconds. How can I do that?

I used like

CString formatStr= _T("''hh':'mm'");
m_TimePicker.SetFormat(formatStr);

But am/pm is not coming.

Because you've not specified such. Use a 't' for that.

CTreeCtrl strange behaviour

Dear All,

I am experiencing a strange problem using CTreeCtrl. I have a dialog in which I have changed the background colour to black using OnCtlColor method.

After that, I have placed a CTreeCtrl and set the properties "HasLines", "HasButtons" and "LinesAtRoot" to true. When I run the program to show the dialog I got Debug Assertion error and when I debug it shows error on the DoDataExhange method and sometimes on the dlgdata.cpp.

But when I change the properties to false there is no debug assertion error. Also, if I didn't change the background using the OnCtlColor and set the properties "HasLines", "HasButtons" and "LinesAtRoot" to true it works fine.

I am very confused with this behaviour. I need background color black for the dialog and want the properties to set TRUE. Please help me to sort out this issue.

Many thanks in advance.

Code snippet for OnCtlColor

HBRUSH MuxInfo::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
	HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
	
	// TODO: Change any attributes of the DC here
	
	UpdateData(TRUE);

	if (pWnd->GetDlgCtrlID() )//== IDC_ALLMSG) //|| pWnd->GetDlgCtrlID() == IDC_MESSAGE)
	{
		// either the listbox or edit box has input focus

		if (m_bFirstTime == TRUE) // First time through function... set up default color
			pDC->SetTextColor(RGB(0,0,0));
		else
		{
			pDC->SetTextColor(RGB(GetRValue(m_crColor),GetGValue(m_crColor),
				GetBValue(m_crColor)));
			pDC->SetBkColor(RGB(255 - GetRValue(m_crColor),
				255 - GetGValue(m_crColor), 255 - GetBValue(m_crColor)));
		}
	}

	return m_brush; // Paint the dialog black!!
	
	// TODO: Return a different brush if the default is not desired
	return hbr;
}

you should put the conditions accordingly on nCtlColor
valid values are :

CTLCOLOR_BTN Button control
CTLCOLOR_DLG Dialog box
CTLCOLOR_EDIT Edit control
CTLCOLOR_LISTBOX List-box control
CTLCOLOR_MSGBOX Message box
CTLCOLOR_SCROLLBAR Scroll-bar control
CTLCOLOR_STATIC Static control

use CTreeCtrl member function SetBkColor(..) to set the background color of tree control.
[added]
one more correction after the conditions return CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
for default case which you don't wish to handle.

return m_brush; // Paint the dialog black!!

// TODO: Return a different brush if the default is not desired
return hbr;

consecutive returns does not make any sense.

Problem in getting hash values [modified]

I want to get hash values from two string. I am using the following code snippet for that purpose

locale loc("English_US");
LONG lValue1 = use_facet< collate<_TCHAR> >(loc).hash(&lpszString1, &lpszString1[_tcslen(lpszString1) - 1]);
LONG lValue2 = use_facet< collate<_TCHAR> >(loc).hash(&lpszString2, &lpszString2[_tcslen(lpszString2) - 1]);

This is working fine. But in a few XP system this piece of code is getting hanged. Do you have any clue what could be the possible reason.

Thanks.

RasDial() howto

eusto23-Sep-08 1:28

I'm trying to use RasDial to connect through a modem to a network
my code:

RASDIALPARAMS rdParams;
rdParams.dwSize = sizeof(RASDIALPARAMS);
rdParams.szEntryName[0] = '\0';
lstrcpy(rdParams.szPhoneNumber, strPhoneNr);
rdParams.szCallbackNumber[0] = '\0';
lstrcpy( rdParams.szUserName, strUserNr);
lstrcpy( rdParams.szPassword, strPassword);
rdParams.szDomain[0] = '\0';

HRASCONN hRasConn = NULL;
dwRet = RasDial( NULL, NULL, &rdParams, NULL, NULL, &hRasConn );

The RasDial call results in a XP bluescreen. Anybody ever got this error? What should i check for?

Thanks

Yes, it is not returning. My whole computer dies.

The fix for me is to use the phone book feature of windows:

RASDIALPARAMS rdParams;
rdParams.dwSize = sizeof(RASDIALPARAMS);

//set the szEntryName to an already defined connection
lstrcpy(rdParams.szEntryName,strPredefinedConnectionName);
//not using these features because they're already defined in that connection
rdParams.szPhoneNumber[0] = 0;
rdParams.szPhoneNumber[0] = 0;
rdParams.szUserName[0] = 0;
rdParams.szPassword[0] = 0;
rdParams.szCallbackNumber[0] = '\0';
rdParams.szDomain[0] = '\0';

HRASCONN hRasConn = NULL;
dwRet = RasDial( NULL,
    "C:\\Documents and Settings\\"
        "All Users\\Application Data\\"
        "Microsoft\\Network\\Connections\\Pbk\\rasphone.pbk", //the system path to the phone book
        &rdParams,
        NULL,
        NULL,
        &hRasConn
        );

It's a bit frustrating that i can't use this to work with "on the fly" dialup connections. The windows blue screen really scares me Sigh | :sigh:

Re: RasDial() howto

David Crow23-Sep-08 3:40

So the only difference is the second argument? MSDN states that if this parameter is NULL, the function uses the current default phone-book file. The default phone-book file is the one selected by the user in the User Preferences property sheet of the Dial-Up Networking dialog box. Do you have this set up?

The difference is in the way i specify the connection to use. I'm telling RasDial to use the strPredefinedConnectionName (ex: a connection named MyDialup that appears in network connections) from the specified phone book.

I've read that in MSDN also but i couldn't find the dialog for this setting. Do you think that the blue screen error is caused by the fact that my default user does not have a phonebook configured?

I would hope not. The BSOD is when Windows has gotten really angry and something totally unexpected has happened in some code. Telling Windows to use a file that does not exist should simply result in a normal "error" message box (i.e., failing gracefully).

I'm sorry I do not have any better suggestions.
