U can do the registration in 'InitInstance' method of Application derived class(before 'DoModal' of the main dialog)

WNDCLASS wc = {0};
wc.style = CS_BYTEALIGNWINDOW|CS_SAVEBITS|CS_DBLCLKS;
wc.lpfnWndProc = DefDlgProc;
wc.cbWndExtra = DLGWINDOWEXTRA;
wc.hInstance = m_hInstance;
wc.hIcon = LoadIcon(IDR_MAINFRAME);
wc.hCursor = ::LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = CreateSolidBrush(GetSysColor(COLOR_BTNFACE));
wc.lpszClassName = <Specify the class name here as well as in .rc>

ATOM cls = RegisterClass(&wc);

It strongly depends on the meaning of such expression, I suppose...
I.e. what is w(k,b)? What is (w(..),w(..),w(..))?

You can execute a particular section in an INF file using the InstallHinfSection function.

For show avi files you can see Nuri Ismail's answer although you can use of MCI functions,for moving images you can make a timer and then you can move images.

How to send a message

Hi,

How can send a message to a running application from another running application.
I tried with FindWindow(), to find the window and PostMessage() to it.
But somtimes FindWindow() is not able to figure out the desired window.

I think I have to use the registred class name instead of Window Name...
So please tell me how to do that..
My app is SDI(VS 2003). And window registration code is

<br />
BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)<br />
{<br />
	if( !CFrameWnd::PreCreateWindow(cs) )<br />
		return FALSE;<br />
	// TODO: Modify the Window class or styles here by modifying<br />
	//  the CREATESTRUCT cs<br />
<br />
	cs.dwExStyle &= ~WS_EX_CLIENTEDGE;<br />
	cs.lpszClass = AfxRegisterWndClass(NULL,NULL,NULL,AfxGetApp()->LoadIcon(IDR_MAINFRAME));<br />
	cs.style |= WS_CLIPCHILDREN|WS_CLIPSIBLINGS;<br />
	return TRUE;<br />
}<br />
<br />

But the AfxRegisterWndClass() return a window name that is like afx:0000:50000......
Is there any way to register the window with user defind name so that I can use this name with FindWindow().

You can use of EnumWindows it gives you a handle to each window and then you can use of ::SendMessage(hwnd,....);

Window taskbar activation issue [modified]

I'm working on a standard Windows SDI application (with menu, toolbar etc.) written using the API ie. no MFC. Currently it has a quirk (though one shared by apps such as Visual Studio and UEStudio). Namely, if I run through the following steps...
1. Open a modal dialog box
2. Then activate another open application by clicking on its icon in the taskbar
3. Click anywhere in that app's window
4. Click on the taskbar icon for my application
... the modal dialog box appears but over the against the background of the other application. It's only when I close the dialog box that my application window re-appears. Any ideas?

Thanks in advance.

I can't say that I see that behaviour (I followed your repro steps with Visual Studio and a couple of other apps). I would tend to say that if VS is acting like that, then your system's setup isn't quite right.

Also - if your app is acting like VS, it can't be doing too much wrong?

Help creating a help dialog

I am trying to create a help file for my program. I wrote a pdf with pictures and text describing how my program works and I wanted to put a button called "help" on my dialog that would open the pdf. But doing this seems quite hard, could someone help me do this? I have tried just opening a blank dialog and adding Static Text but quite frankly I think that looks like crap. Maybe I am approaching the problem from the wrong angle. Is there some easier way to do this? Any help would be appreciated.
