CListCtrl problem, let it show color 1 in odd row and color 2 in even row

I've learned some code and idea from others, I can achieve my goal by mapping the message ON_WM_DRAWITEM, and override the method

void CMyListCtrl::DrawItem(somecode)

But I have no idea when does my CMyListCtrl trigger the DrawItem? Even I add the code AfxMessageBox(_T("tell me you DrawItem")); in void CMyListCtrl::DrawItem(somecode), it doesn't kick my ass at all. I am so confused.
My ideas got from others,

// Draw the background color<br />
	if( bHighlight )<br />
	{<br />
		pDC->SetTextColor(::GetSysColor(COLOR_HIGHLIGHTTEXT));<br />
		pDC->SetBkColor(::GetSysColor(COLOR_HIGHLIGHT));<br />
<br />
		pDC->FillRect(rcHighlight, &CBrush(::GetSysColor(COLOR_HIGHLIGHT)));<br />
	}<br />
	else<br />
	{<br />
		CRect rcClient, rcRow = rcItem;<br />
		GetClientRect(&rcClient);<br />
		rcRow.right = rcClient.right;<br />
<br />
		pDC->FillRect(rcRow, &CBrush(nItem%2 ? ::GetSysColor(COLOR_WINDOW) :<br />
	 					RGB(255,255,0)));<br />
	}<br />

So I thick I just need some demo code to teach me. Does Anybody kind to make a demo project implementing that: in the list control, in the odd row, fill color 1, but in the even row, fill color2.

pDC->FillRect(rcRow, &CBrush(nItem%2 ? ::GetSysColor(COLOR_WINDOW) :
	 					RGB(255,255,0)));

is what I want actually.
Do I describe my problem clearly?

I'm currently using the Beep method to make, well a beep Poke tongue | ;-P

, sound when an action occurs. This works well on my development machine (a laptop) in the fact that it plays the beep through the sound card to my headphones/speakers. However on the machine the program will run on the beep comes out of the system speaker (the one that makes beeps on startup). Does anyone know if there is a similar method that will allow me to always direct the output through the sound card?

I don't want to start playing sound files as all I need is to play a beep at a set frequency for a set period of time, so something very basic Big Grin | :-D

how to monitor exe and dll interactions?

Hello everyone,

Are there any tool or other methods which could be used to monitor which class/method exe is accessing a DLL?

Now I met with an issue that when I provide the DLL I developed to a 3rd parth application, it will crash sometimes and I suspect the 3rd party application is invoking some class/method which I do not implement the DLL. I have the full source codes of the DLL, but has no source codes of the exe so I am wondering whether there are some methods to monitor the interactions -- e.g. I can monitor which class/method the exe is invoking and at the same time my DLL has not implemented.

I am using Visual Studio 2005 to develop native (unmanaged) C++ DLL, and I expose the interface of the DLL to exe through COM interface.

thanks in advance,
George

Thanks Jonathan,

I have used the tool before and I think it could only find the static dependencies of an EXE, for example the DLLs which is implicited linked to the EXE. For the DLLs which the EXE uses LoadLibrary to dynamically load at runtime on demand, does this tool provide the function to monitor?

George

Hi George,

It does you need to use the profile menu item, you'll then see all dynamically loaded DLL's as your application loads them, either on start up or using LoadLibrary()

Thanks Jonathan,

I have tried to enable all the checkbox in Profile menu and it could monitor which module is loaded at runtime, but it could not tell which method is invoking -- does the tool support? Do I need some special settings?

Getting active and past local users of system

Hi All,

I m using NetWkstaUserEnum() function for getting active users of system.

1) But when I m using this function on windows XP, it works fine on some XP system & for some XP system it gives one user name twice which I don’t want.

2) In server system like windows 2k3 server, we can add other users as remote desktop users other than actual users of system. Total users of that system will be actual users & remote desktop users. More than one users can login to that system at a time.
Consider user1, user2, user3 are actual users of system & user4, user5, user6 are remote desktop users of windows 2003 server system. User1 is currently login. Remote desktop user user4 is logged in & logged out. Remote desktop users user5 & user6 are also logged in. now when I use function NetWkstaUserEnum() for getting active users, expected result is user1, user5 & user6 but it gives the user1 three times & user4, user5, user6. User4 is logged in & logged out, still it giving that user name. I verify this output with one of the tool available on codeproject, it also giving same output which I getting using that function. I don’t whether I m making mistake or is the problem with system. If I m using other API, let me know the API which will give me exact result.

3) Currently I m extracting past local users means which are not currently login from registry. I want to know the API if available for getting past local users.

Thanks,
Subhash

What is "past local users?" Are those accounts that have not been logged into for some period of time?

Ya, past local users means u can say passive users or the users which are available on system but not currently login.

You might try NetQueryDisplayInformation() or NetUserEnum(). Another item of interest is NetWkstaUserEnum().

Getting PID of process of network sockets(TCP, UDP) on windows 2000

Hi All,

I m using GetTcpTable() & GetUdpTable() for getting information of network sockets(TCP, UDP) but it doesn’t give PID of process. Therefore I used GetExtendedTcpTable() & GetExtendedUdpTable() for getting information of network sockets which gives PID also. But those two function doesn’t work on windows 2000. I want to know the API for windows 2000 which will give me the information of network sockets along with PID.

From the MSDN[^]

It looks like you just call it with a path and the ID of your control. It seems to know how to populate it.

here's a code sample from the MSDN

// If pDialog points to a CDialog object with a combo box<br />
// with the identifier IDC_COMBO1, this call will populate<br />
// the box with only the non-hidden subdirectories in the root<br />
// directory of the C:\ drive. <br />
<br />
TCHAR szPath[MAX_PATH];<br />
_tcsncpy_s(szPath, MAX_PATH, _T("C:\\"));<br />
pDialog->DlgDirListComboBox(szPath, IDC_COMBO1, 0, DDL_EXCLUSIVE | DDL_DIRECTORY);<br />
<br />
// Note that the first argument is a string and not a string <br />
// literal. This is necessary because DlgDirListComboBox <br />
// modifies the supplied string. Passing a string literal <br />
// will result in an access violation.

osVersion.dwOSVersionInfoSize = sizeof(osVersion);

GetVersionEx( &osVersion );

bool isVista = (osVersion.dwMajorVersion==6) && (osVersion.dwMinorVersion==0);
