Doubt in CTreeCtrl

I have created a tree control and added few items in it.
And i have used TVN_SELCHANGED notify message as below.
But i am not able to get item names using LPNMTREEVIEW structure instead its showing junk chars.

void CMyDlg1::OnTvnSelchangingTreectrl(NMHDR *pNMHDR, LRESULT *pResult)
{
   LPNMTREEVIEW pNMTreeView = reinterpret_cast<lpnmtreeview>(pNMHDR);

   CString str = pNMTreeView->itemNew.pszText; //junk values?
   
   CString str1 = m_TreeCtrl.GetItemText(m_TreeCtrl.GetSelectedItem()); // OK

   .....
}</lpnmtreeview>

According to MSDN, that is to be expected.

"The itemOld and itemNew members of the NMTREEVIEW structure are TVITEM structures that contain information about the previously selected item and the newly selected item. Only the mask, hItem, state, and lParam members of these structures are valid. The stateMask members of the TVITEM structures specified by itemOld and itemNew are undefined on input."

To set screen resolution, you've to use ChangeDisplaySettings(). For that this[^] will help you. May need to have a look at this[^] too. And I think you can dig out better how to use them. Smile | :)

Use of SetProcessAffinityMask

Hi All !

I'm running an application that spwans several processes and threads, it runs on Windows 2003 Server OS and using 8 cpu's machine(Xeon).
We are considering the use of SetProcessAffinityMask to allocate heavy processing jobs to a spcific cpu. My question therfore is this:

Using SetProcessAffinityMask, is it possible to tell the OS that I want my process to be the only one using that cpu (i.e. no other process, mine or the OS's, is allowed to run on it) ? is it possible ? Unsure | :~

We wish to get deteministic results when system is working for long periods of time.

thanks,
Amit Smile | :)

I don't believe so.

You may want to use SetThreadAffinityMask to distribute threads among processors,
but there's no guarantee the system will actually use your suggestions.

Try it and test it thoroughly to see if you're actually getting any benefit -
from my experience, on XP and above, the OS thread scheduler does a pretty good
job without intervention.

If you wish to pass command line arguments in IDE go to "Project | Properties | Debugging | Command Arguments". Here you can specify your command line arguments.

Hope this will help you.

You can use MSXML[^] for doing XML related stuffs. The following articles will be useful.

1) Using MSXML to read XML documents[^].
2) CXml - A Wrapping Class for MSXML 3.0/4.0/5.0/6.0[^].
3) Plus a lot of articles in CodeProject XML Section[^].

Download the Microsoft XML Parser SDK and dig through the documentation. You'll probably find that using smart pointers and the DOM approach to be adequate for most scenarios.

The Rectangle function draw the border with the currently selected pen. So to get a dark border, before calling Rectangle, select a pen with dark color as show below

CPen DarkPen( PS_SOLID,1, RGB(0,0,0));
pDC->SelectObject( &DarkPen );
pDC->Rectangle(rectrect.left,rectrect.top,rectrect.right,rectrect.bottom);
