Are you sure that it is not just a formatting problem, are you formatting them as unsigned?

Can you tell Where the values are changing?
Do you mean the function getting different values other than you want to pass (or) the parameters changed after the function call?
Without source code its difficult to guess what is the problem.

A char represents a signed byte.
The bit patterns of the unsigned chars {225,226,227} are, of course, the same of the chars {-31,-32,-33}{-31,-30,-29}. You have to cast the data unsigned char, before passing it to your function.

It is part of platform SDK. Get latest platform SDK from MS site.

Hi peopl..
is there any way i can know the APIs included in each of the headers of C++ ? i use dm for simple C++ programs.. i do have vc++.. but the binaries i get from that runs only on systems that have .net framework installed..
i jus want to the list of functions included in each headers that is available with any C++ compiler..
also i use dm and its a command-line compiler.. do IDE compilers have integrated help with the headers? if so which is preferred over VC++ ?

You need to open that header, to know that.

MDI maximized child bug

hsuch5-Apr-07 19:03

Hi all,
It is very common to create a mdi child in a initially maximized state in some cases. I set SW_MAXIMIZE style in the MDICREATESTRUCT structure then send a message to mdi client window. After that, I saw twin sizing boxes on the top-right corner of my frame window (a pair of [Min][Max][Close] tri-buttons). If I restore the child window, the child got one and there was still one remaining on the corner. I was using Win32 SDK, not MFC. The code I used to create the child is like this:

HWND child_createWnd(HWND hwndClient, int x, int y, int w, int h, TCHAR szCaption[], TCHAR szFilename[])
{
	HWND hwndChild ;
	MDICREATESTRUCT mdicreate ;

	if(!childClass) childClass = zw_child_registerClass();

	mdicreate.szClass = szChildClass ;
	mdicreate.szTitle = szCaption ;
	mdicreate.hOwner  = GetModuleHandle(0) ;
	mdicreate.x       = CW_USEDEFAULT ;
	mdicreate.y       = CW_USEDEFAULT ;
	mdicreate.cx      = CW_USEDEFAULT ;
	mdicreate.cy      = CW_USEDEFAULT ;
	mdicreate.style   = WS_VSCROLL | WS_HSCROLL | WS_MAXIMIZE; <code>//MAXIMIZE window style</code>
	mdicreate.lParam  = (LPARAM)szFilename ;

	hwndChild = (HWND) SendMessage (hwndClient,
		WM_MDICREATE, 0,
		(LPARAM) (LPMDICREATESTRUCT) &mdicreate) ;

	return hwndChild;
}

I followed Petzold's sample code (cha18, Programming Windows 5ed.)to do this. I wander if I missed something. So I tried it on the sample code directly and add the flag to the style, but still happened.
Did anyone ever get this problem? I'm very thankful if anyone can help me.

I read "Daniel Bowen, Creating a new MDI child: maximization and focus issues" and got some idea. I should handle redraw and focus issues. Set the client window as MDIS_ALLCHILDSTYLES style and change the function to :

HWND child_createWnd(HWND hwndClient, int x, int y, int w, int h, TCHAR szCaption[], TCHAR szFilename[])
{
	HWND hwndChild ;
	MDICREATESTRUCT mdicreate ;
	int fMax = 0;
	
	if(!childClass) childClass = zw_child_registerClass(); 
	
	mdicreate.szClass = szChildClass ;
	mdicreate.szTitle = szCaption ;
	mdicreate.hOwner  = GetModuleHandle(0) ;
	mdicreate.x       = CW_USEDEFAULT ;
	mdicreate.y       = CW_USEDEFAULT ;
	mdicreate.cx      = CW_USEDEFAULT ;
	mdicreate.cy      = CW_USEDEFAULT ;
	mdicreate.style   = <code>WS_OVERLAPPEDWINDOW | WS_CHILD | WS_CLIPSIBLINGS | WS_VSCROLL | WS_HSCROLL;</code>
	mdicreate.lParam  = (LPARAM)szFilename ;	
	
	<code>SendMessage(hwndClient, WM_SETREDRAW, FALSE, 0); /* Disable redraw */ </code>

	hwndChild = (HWND) SendMessage (hwndClient,
		WM_MDICREATE, 0,
		(LPARAM) (LPMDICREATESTRUCT) &mdicreate) ; 

		
<code>	/* Should maximize? */
	SendMessage(hwndClient, WM_MDIGETACTIVE, 0, &fMax);
	fMax? ShowWindow(hwndChild, SW_MAXIMIZE) : ShowWindow(hwndChild, SW_NORMAL);
	
	/* Handle focus here */
	SetFocus(hwndChild);
	
	/* Enable and redraw */
	SendMessage(hwndClient, WM_SETREDRAW, TRUE, 0); 
	RedrawWindow(hwndClient, NULL, NULL, RDW_INVALIDATE | RDW_ALLCHILDREN);</code>	
	

	return hwndChild;

Right now everything is correct except very slow. If you have better idea, please let me know, thanks.

OK then I've got a problem, because my version of gl.h doesn't have it.

hi,all
Here I have a dialog box, a edit control and a list control, dialog box is the parent of both edit and list.
Now I want to overlap a edit control onto a list control, I use m_Edit->SetWindowPos(&m_List,.....), However, when I click mouse in edit control, message still pass to list control not edit control, how to solve this?Thanks.

try calling m_Edit->BringWindowToTop() in the onInitDialog() funtion.

are you trying to make the cells in the listctrl editable? If so its better to make the edit control as the child of the list ctrl.
