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.

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

one question regarding dialogz!!!!!

4-Mar-05 1:23

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;
}

cheerz.....

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??

Unless they are constantly being used and not being released, the number of variables in a class is irrelevant.

rateep wrote:

Declaring a variable is not the issue here, not releasing a device context is. If the DC is private, you can have and use as many of them as you like. The limit of 5 is for common DCs.

Sounds like you might need a tabbed dialog instead.
