Right. I would use a container instead of a raw array. But then again, you do know that City points to the first item as that is the address returned by new. I suppose that you mean that the pointer can be modified inadvertently (or even on purpose) in the program since it's not const - but hey, this is not VB, you're supposed to know what you do with your pointers! Poke tongue | ;-P

Unfortunately I don't think using a const pointer will work in this instance as the size of the array is not known at declaration/definition time but only after the XML file is read (numberofcities is read from the XML file according to the OP).

Cheers

There are some pre-build objects in that folder if you've compiled your project before. When you hit 'build', VC will try to reduce compile time by using object files that aren't changed. The problem is that VC sometimes fails in determining what's changed.
I think you could have chosen 'Rebuild' with a similar successfull result.

Probably "Rebuild all" would have worked too. But there's more. Once I had to delete a few compiler-generated files from the project's main folder. I think it was a .aps file, a .ncb file or even the classwizard .clw file. VC gets buggy from time to time, so if you are desperate, just try anything, delete every file that's not code and see what happens.

Of course, but whether you write your own class or use someone else's, the net result is the same. You can always dissect the CXListCtrl class to see how "bold" is implemented.

In ShellExecute, make nShowCmd = SW_HIDE.....

Use CreateProcess like this

STARTUPINFO si;
PROCESS_INFORMATION pi;

ZeroMemory( &si, sizeof(si) );
si.cb = sizeof(si);
ZeroMemory( &pi, sizeof(pi) );

// Start the child process.
if( !CreateProcess( NULL, // No module name (use command line).
"MyChildProcess", // Command line.
NULL, // Process handle not inheritable.
NULL, // Thread handle not inheritable.
FALSE, // Set handle inheritance to FALSE.
0, // No creation flags.
NULL, // Use parent's environment block.
NULL, // Use parent's starting directory.
&si, // Pointer to STARTUPINFO structure.
&pi ) // Pointer to PROCESS_INFORMATION structure.
)

hope this helps

By default, I do not think that WinZip can be ran without some sort of user interaction. You can, however, download the command-line add-on from here. That would allow you to use WinZip in an automated fashion.

Set background colour on a CDateTimeCtrl

roccap3-Mar-05 22:46

I'm trying to set the background color and text colour on a CDateTimeCtrl, when its in its non dropped down state. I thought I could treat it like a std window and derived a
class from CDateTimeCtrl and then overode the OnCtlColor function and set the text/background colour in there, but it doesn't seem to work.
Am I doing something wrong or this not the way to do it for such a control?

TIA

u already have an example in the msdn documentation,just incase u didnt get em,here it iz.....

// This OnCtlColor handler will change the color of a static control
// with the ID of IDC_MYSTATIC. The code assumes that the CMyDialog
// class has an initialized and created CBrush member named m_brush.
// The control will be painted with red text and a background
// color of m_brush.

HBRUSH CZilchDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
   // Call the base class implementation first! Otherwise, it may
   // undo what we're trying to accomplish here.
   HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

   // Are we painting the IDC_MYSTATIC control? We can use
   // CWnd::GetDlgCtrlID() to perform the most efficient test.
   if (pWnd->GetDlgCtrlID() == IDC_MYSTATIC)
   {
      // Set the text color to red
      pDC->SetTextColor(RGB(255, 0, 0));

      // Set the background mode for text to transparent 
      // so background will show thru.
      pDC->SetBkMode(TRANSPARENT);

      // Return handle to our CBrush object
      hbr = m_brush;
   }

   return hbr;
}

i have designed a dialog based application having many controlz(derived static controlz).....now i am supposed to add a new page to thiz dialog(what i mean is that i should be able to show the same dialog with different controlz on the dialog).....what r my chances of doing it on the same dialog without calling an another dialog????? Confused | :confused:

ps:right now i am able to load VISUALLY the second page of the panel BUT THE CONTROLZ OF THE FIRST PAGE REMAIN THERE(THOUGH VISUALLY NOT VISIBLE!!!!!)

Hi Rateep,

If u want to display second page of panel in diff dialog... you can insert New Dialog to yr workspace, and add required controls.

If you want to pass some data from first dlg to second dlg then take HWND member of first dlg to yr second dlg. and create temp dlg when u need those data( using ::FromHandle() )

when u show second dlg you can hide first dlg by calling (ShowWindow(SW_HIDE))

doing both panels in one dlg is ok if u can handle SHOW / Hide of Such controls ... if there are more controls then i suggest to use another dlg.

Hope this helps

I agree with David.
In addition to that it's too much coding effort on your part Mad | :mad:

You can make use of:

<br />
CWnd::ShowWindow(SW_SHOW / SW_HIDE);<br />

Adding a second dialog resource is cheap. Making a single dialog assume multiple personalities is, in most cases, not time well spent.

That is a very strange requirement. As has already been mentioned, use ShowWindow() to selectively show/hide the controls.

well david.....thanx again for the reply,u c i have many dc memory variables in each dailog,and loading all the dialogz at one time(three dialogz having abt 5 dc memory variablez) and hiding all except one maynot be possible coz of the limited number of dc memory variables that can be declared at a time.....so the show/hide aint a good idea.....the rpob is i have already made it a dialog based application(since the inital reqirement was just one graphics panel)now itz made two,now since it would be quite an amount of work to make it an mdi i plan to call from the main dialog(panel),the second(or third dailog or panel) and transfer then destroy the main first dialod(panel)and transfer the parent control to this panel that is called.....what do u think?will that work??
