I've overriden the funx CMyButton::DrawItem(), and some lines in it are:
CDC* pDC = CDC::FromHandle( lpDrawItemStruct->hDC );
CRect rc = lpDrawItemStruct->rcItem;
CPen pen( PS_SOLID, 1, RGB(0,0,0) );
CPen *pOld = pDC->SelectObject( &pen );
pDC->LineTo( rc.right, rc.top );
pDC->LineTo( rc.right, rc.bottom );
pDC->LineTo( rc.left, rc.bottom );
pDC->LineTo( rc.left, rc.top );
pDC->SelectObject( pOld );
But the prob occurs that only the upper and left borders drawn can be seen while the lower and right can't. At first, I thought it was caused by the 3D effect of the button. But though I've added BS_FLAT, the prob still exists. In fact, I can't use the following to draw the borders:
pDC->Rectangle( &rc );
Cos I want the button background to be transparent so that the back image of the dialog isn't covered.
So anyone knows about this kinda prob and helps me out?
Really thx!

1st I miss a pDC->MoveTo( rc.left, rc.top ); for the starting point before the first LineTo()
2nd Have you tried to change rc.bottom and rc.right? Decrement both should be enough to see the right and bottom lines. The rcItem rectangle defines the controls boundaries, painting outside this boundaries is prohibited by clipping.

Really thx!
In fact, pDC->MoveTo() isn't needed cos the GDI defines the starting point as the left-top automatically.
And I use
rc.DeflateRect(0,0,1,1);
Thus the borders are all visible.

I am trying to create a windower/filterer for an old win95 game (Z) so that I can apply a choice of pixel scaling filters (sai,hq3x etc). Could anyone point me in the right direction? I have an understanding of the filtering algorithms, I just don't know how to link a frontend to the original program
thanks in advance

This is complicated to the extreme:
On windows your game will run under the VDM (Virtual Dos Machine). This will work until Windows Vista, later operating systems do not support the VDM anymore. So any solution that you build on Windows is bound for obsolescence. Anyway, intervening in the screen driver of the VDM is probably near to impossible.
I suggest tackling it in a different way:
Get yourself a copy of good open-source Virtual Machine Software (VirtualBox comes to mind). Install windows 95 and your game on a virtual machine. Locate the screen driver in the Virtual Machine Software, and adapt it to your needs.
Good Luck

I see, i'll have a look at some vm source then 
out of interest, I have seen some windowers before (for ffxi for example) any idea how they manage it? I guess they must be very specialised for the specific program

This is a problem with the monitor florescent tube (backlight) that is mounted on the notebook NOT with an external display via serial port or RS 232 technology.
I changed my OS from Windows XP MCE to XP Pro and my brightness controls no longer work. I am looking for a way to address the backlight with an OCX or API call using Visual Basic.
Here is my answer in C
http://msdn.microsoft.com/en-us/libr...8VS.85%29.aspx
I dont write C but if I could get that in an OCX I am sure I would be in business.
I could instruct the OCX from Visual Basic.
To be honest this is a HUGE problem. I am learning that ALL notebook manufacturers do it this way. They release a model with the OS installed and a driver to take care of the florescent monitor tube / baklight. If you change the OS at any time you very possibly will not find a driver for that model with that OS. I have seen and read thousands of articles so far of people asking desperately for a fix. If I can get an OCX method I intend to make a simple way to address the backlight (florescent tube behind monitor) directly and behave exactly the same as the simple driver is supposed to and I will offer it for free to anyone who wants it.

Hi All
I am using CD/DVD burning program using windows api in windows service pack2.I am using ICDBurn Interface to burn CD/DVD . When I burn CD then it works ok but when I burn DVD then It did not work.
In brief first I copied the file using SHGetSpecialFolderPathA() at the cd burn path then I use ICDBurn interface to burn the DVD. How i solve this problem.

You'll have to find some other method, DVD burning was included in the OS starting with Vista, this won't work on XP
|
|
|
|
|
I have Installed IMapiv2 on my xp service pack2 after reading and downloading from http://support.microsoft.com/kb/KB932716\ link. Still it is not working but IMapiv2 on vista capable of burning dvd. I have checked it.
|
|
|
|
|
Should work using that. Note that XP SP2 is unsupported. Can you try upgrading to SP3?
|
|
|
|
|
It is not working on xp Service pack3 too.
|
|
|
|
|
Have you re-installed the hotfix after upgrading?
If yes, I'm out of options.

Ok, im trying to get data by hooking GetQueuedCompletionStatus. Number of bytes are always correct, but im not sure how to get data. I guess it;s in OverLapped structure ?

I try to embed the window of my program in the desktop.<big>The window is under the desktop icons without covering them!</big>
I have tried the following method.
As far as I know,the desktop consists of four sub-layers.Using spy++,I find the first three layers--1.SysListView32 2.SHELLDLL_DefView 3.Program Manager.
I tried to put my window on top of the second layer.
<pre>BOOL CTestDialogDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Add "About..." menu item to system menu.
// IDM_ABOUTBOX must be in the system command range.
ASSERT((IDM_ABOUTBOX &amp; 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX &lt; 0xF000);
CMenu* pSysMenu = GetSystemMenu(FALSE);
if (pSysMenu != NULL)
{
CString strAboutMenu;
strAboutMenu.LoadString(IDS_ABOUTBOX);
if (!strAboutMenu.IsEmpty())
{
pSysMenu-&gt;AppendMenu(MF_SEPARATOR);
pSysMenu-&gt;AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
}
}
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon
// TODO: Add extra initialization here
HWND tmpHandle = ::FindWindow("Progman",NULL); //the hwnd of the third layer
tmpHandle = ::GetWindow(tmpHandle,GW_CHILD); //the hwnd of the second layer
CWnd* pWndDesktop = CWnd::FromHandle(tmpHandle); //get the window of the second layer
this->SetParent(pWndDesktop); //set the second layer window as the parent of my window
tmpHandle = ::GetWindow(tmpHandle,GW_CHILD); //the hwnd of the first layer
::SetWindowPos(tmpHandle, HWND_TOPMOST, 0, 0, 0, 0, SWP_SHOWWINDOW|SWP_NOSIZE); //bing the first layer to the top
return TRUE; // return TRUE unless you set the focus to a control
}</pre>
However,this method dosen't work.Does anybody have some guidance on how to do this?

I can think of 2 things:
1. Use Active Desktop[^], you would somehow activate the "active desktop" feature of windows (don't know if that still exists above 'windows xp' - UPDATE on this: they say under Vista this has been replaced by the Sidebar thing so i guess it is no longer there), set a local HTML page as the source and somehow embed your application into that (thorough a plugin or somesuch).
2. Try to subclass the list view and experiment with handling its WM_PAINT and/or WM_ERASEBKGND messages along with the user input as needed, you probably need to hook into explorer.exe to do this.
A combination of these 2 methods could be to enable Active Desktop, show an empty page and then try to subclass the HTML view that displays the HTML page in the background and then do your own drawing.

Packaging your C++ application as an ActiveX control would be the logical choice.

You should never, ever do this.
If you use the desktop as your parent window, and then display a modal dialog box, you will effectively hang the system.
http://blogs.msdn.com/oldnewthing/archive/2004/02/24/79212.aspx
The window you retrieve from GetDesktopWindow is the parent window of all the windows in the system, and it is not visible, (it is completely covered by it's children). You could try forcing WM_PAINT, after you get a DC through GetDCEx, setting DCX_CLIPCHILDREN to false, but this will result in painting Over the Controls.
Maybe subclass the listview which contains the icons, and do your painting on that one. That should work.
About the Active Desktop solutions mentionned here: Active desktop has been canned with Windows XP 64 bit. Vista and Weven don't carry it anymore. Desktop Gadgets is the flavor of the day.

closesocket(IPv4);

WSACleanup();
I spent sometime using Network Monitor only to find that HostName resolving isn't returning an accurate IP to the UNICODE use.
char *HostName = (char *)malloc(MB_CUR_MAX);
wctomb_s( NULL, HostName, MB_CUR_MAX, (wchar_t)Download->HostName);
If anyone has any pointers to solving the problem it will be appreciated.
