But there is a problem..

Consider There is an edit control and a staic control in the dialog.. Using the SetwindowPos I moved the staic control over the edit control( only half overlapped). But now if I clicked in the edit control, it will paint over staic control..

You can always process the WM_SETFOCUS (or similar) message and the bring the window to the background/front Big Grin | :-D

But consider if static control was created as popup window we need not have to take care of any message.. The underliying edit control will never draw over it..

No, that is not what I want...
I just want it as Popup, like the popup dialogs. I should not be clipped by the client of the parent.

Then,

depending on the type of the control you want to make "popup" there can be different approaches, but you can try to make a popup window (a real window) and moving the control to that window using SetParent/SetOwner.

The control is custom calendar derived from CMonthCalCtrl. It is created as a dlg item and a member variable is assigned. So it is basically a child. Now I want to give it popup style with out changing the parent, because the parent needs the messages from it.

Please note that if we create the same control dynamically with popup style it is working fine.

try using SetWindowLong and GetWindowLong

SetWindowLong(GetSafeHwnd(),GWL_STYLE,~WS_CHILD & WS_POPUP | GetWindowLong(GetSafeHwnd(),GWL_STYLE));
	RedrawWindow(NULL,NULL,RDW_ERASE | RDW_INVALIDATE | RDW_FRAME | RDW_ALLCHILDREN);

Change the hwnd parameter of the SetWindowLong And GetWindowLong of which you want to change the style.

I have tested it... and this code will do the job:

<br />
    {<br />
      long x;<br />
      // B!: Control to change<br />
<br />
      x=GetWindowLong(B1, GWL_STYLE);<br />
<br />
      x&=~WS_CHILD;<br />
      x|=WS_POPUP;<br />
<br />
      SetWindowLong(B1, GWL_STYLE, x);<br />
      UpdateWindow(B1);<br />
      SetParent(B1, NULL);<br />
<br />
      // You may want to move the control somewhere since<br />
      // previous coord was Client Coords.. control gets <br />
      // misplaced<br />
      SetWindowPos(B1, NULL, X, X, 0, 0, SWP_MOVE|SWP_NOSIZE|SWP_NOZORDER);<br />
    }<br />
<br />

I'm getting more and more confused...

WS_CHILD is not compatible with WS_POPUP, so your control is a child window or a popup window, can't be an hybrid. If you change WS_CHILD to WS_POPUP then you must change the parent window to NULL. See SetParent on MSDN remarks section:

For compatibility reasons, SetParent does not modify the WS_CHILD or WS_POPUP window styles of the window whose parent is being changed. Therefore, if hWndNewParent is NULL, you should also clear the WS_CHILD bit and set the WS_POPUP style after calling SetParent. Conversely, if hWndNewParent is not NULL and the window was previously a child of the desktop, you should clear the WS_POPUP style and set the WS_CHILD style before calling SetParent.

If the control have a parent differen than the Desktop your control MUST be WS_CHILD, otherwise it MUST be WS_POPUP.

I use ModifyStyle( WS_CHILD, WS_POPUP ); to change the style.

If I create the control dynamically as popup its parent can be dialog wnd. And it is working fine as I desired. The dialog wnd is passed as the parent to create the control. And using a spy I can identify that the parent is the dialog itself.

I just want to make the control created as child, to be the same as I created dynamically. Hope you can understand what I am trying to do. Smile | :)

The function SetWindowText expect a char array, not a long. So use sprintf to convert this value into a char array:

char szBuff[50];
sprintf(szBuff,"%l",n);
status->m_TOTAL_WORDS.SetWindowText(szBuff);

Can u please also tell me how to change it int to char ??

TCHAR buffer1[50];
int f=INDX.getTotalFiles();
_ltoa(f,buffer,10);

Oops, I misunderstood his question. I thought he was asking about the line that does the conversion.

pleast look at my reply to whitesky. And Btw, you can still use ltoa for converting ints to chars. int is not something totally different from long. but Only the size Wink | ;)
