Handling Windows Messages on Another Application

Hi,

I am working on disabling menu options,tool bar options and handling windows messages on another application.
I am able to disable the menu options of another application by getting
a handle to that application using FindWindow API.

Is it possible to handle the windows messages on another Application?
I want to disable the right click option on another application.
Is it possible? Any suggestions would be appreciated.

Thanks

Windows hooks! See, for instance, the articles API hooking revealed, Hooks and DLLs and, of course, the documentation ^.

I've created a Single Document MFC Project. If I run this project,a window opens. If I select File->Print or File->Save, the corresponding Dialog opens. But If I select File->Open from the File menu
the File Open Dialog doesn't open. How can I do this? Pls help.

Revise your Menu in the resource editor and ensure that you have ID_FILE_OPEN in the Menu option File->Open.
it should be automatically included.

BTW you can always call CMyDocument::OnOpenDocument (); it should have a call to CDocument::OnOpenDocument (lpszPath) inside.

Call SetFont() function of the list box( CListBox ).

Click on the "?" button in your VC++ toolbar, go to the "index" tab in the help and write CListBox, then choose class members, look for SetFont () and click on it. You will have the info there

Haven't u heared of MSDN? Sigh | :sigh:

Create a CFont object as member variable of the class. say m_font.

After that..

m_font.CreatePointFont( 200, "Arial" );<br />
m_ListBox..SetFont( &m_font, TRUE );

See CFontListBox[^] of course I didnt see it uses of SetFont for listbox or no but I think if you are new to vc++ its helpful for you.

Why I meet a mistake when I play a WMV file using mciSendCommand?

Hi! Everyone!
Now I'm developing an application which will play a .wmv file. I do it using mciSendCommand. But a mistake will happen sometimes. The description of it is: "the alias had been used by other program, plz use the unique alias."
This mistake can't happen everytime. The application was executed only once. So it isn't make by two program executing at same time. I hope someone can tell me the reason and how to resolve it. Thx!
The code is as below:

<br />
	MCI_DGV_OPEN_PARMS mciOpen;<br />
	MCI_DGV_STATUS_PARMS mciStatus;<br />
	UINT uDeviceID;<br />
	HWND hwndVideo;<br />
	RECT video_rect;<br />
	//<br />
	ZeroMemory(&mciOpen,sizeof(MCI_DGV_OPEN_PARMS));<br />
	mciStatus.dwItem=MCI_DGV_STATUS_HWND;<br />
	mciOpen.lpstrAlias=_T("thevideo");<br />
	mciOpen.lpstrElementName=(LPWSTR)m_szVideoName.GetString();<br />
	mciOpen.hWndParent=this->m_hWnd;<br />
	mciOpen.dwCallback=(DWORD)this->m_hWnd;<br />
	mciOpen.dwStyle=WS_CHILD;<br />
	//<br />
	DWORD ret = mciSendCommand(0,MCI_OPEN,MCI_OPEN_ALIAS|MCI_OPEN_ELEMENT|MCI_DGV_OPEN_PARENT|MCI_DGV_OPEN_WS,(DWORD)&mciOpen);<br />
	if(ret != 0)<br />
	{<br />
		CString dbg_str;<br />
		wchar_t str[100];<br />
		CMajoyComLog::WriteDefaultLog(L"Can't open this file:"+m_szVideoName);<br />
		mciGetErrorString(ret,str,100);<br />
		dbg_str.Format(_T("Error occured：%s"),str);<br />
		CMajoyComLog::WriteDefaultLog(dbg_str);<br />
		MessageBox(m_szVideoName + _T("Can not open Media File"));<br />
		return 0;<br />
	}<br />
	else<br />
	{<br />
		uDeviceID=mciOpen.wDeviceID;<br />
		mciSendCommand(uDeviceID,MCI_STATUS,MCI_STATUS_ITEM,(DWORD)&mciStatus);<br />
		hwndVideo=(HWND)mciStatus.dwReturn;<br />
		// Window position.<br />
		::GetClientRect(hwndVideo,&video_rect);<br />
		//::SetWindowPos(hwndVideo,HWND_TOP,<br />
		//	video_rect.left,video_rect.top,video_rect.right-video_rect.left,video_rect.bottom-video_rect.top,<br />
		//	SWP_SHOWWINDOW|SWP_DEFERERASE);<br />
		//RECT rc;<br />
		//GetWindowRect(&rc);<br />
		//SetWindowPos(&wndTop,<br />
		//	rc.left,rc.top,video_rect.right-video_rect.left,video_rect.bottom-video_rect.top,<br />
		//	SWP_SHOWWINDOW|SWP_NOREDRAW);<br />
		ShowWindow(SW_SHOW);<br />
		UpdateWindow();<br />
	}<br />
	mciSendString(_T("play thevideo"), 0, 0, 0);<br />
	GetParent()->PostMessageW(WM_VIDEO_START);<br />
	SetTimer(1,1000,NULL);<br />
<br />
	m_szVideoName.ReleaseBuffer();<br />

Hello All,
i worked on a application which is SDI using mfc with VS 2005.
when i start this application it takes arround 20.5MB memory.
if i minimize it once than it shows only 1.7MB memory which is actual.

so please tell me what have to do so without minimze the application it should take only 1.7 MB memory.

please share your knowledge with me.

thanks
Bankey

Minimizing does not normally reduce memory footprint substantially so your program must be responding to being minimized by running some special function.
You need to look for what happens on minimize to find where the extra memory is used and if it's all needed. Also make sure your memory usage figures take into account all types of memory, ordinary ram heap, virtual memory, non-paged pool.
Memory usage is application specific so I can't advise you any further without a detailed understanding of what your app is doing.

Nothing is exactly what it seems but everything with seems can be unpicked.

Performance Profiler For Visual C ++ 6.0

Hello,
Can any body suggest the Performance Profiler For Visual C ++ 6.0 . Is there any Open source Performance Profiler Available ?

You could try and pick up and old version of NuMega Dev Partner C++, probably some on Ebay. I seem to remember that had profiling that worked OK. It needed huge amounts of RAM at the time though, perhaps even 512MB for descent performance Laugh | :laugh:

If you can afford it, use VTune from Intel. It works fantastically well.
We use it for performance analysis and to locate perforance bottlenecks.
You don't have to build your program particularly differently for it to work, either.

how to send message to a window to inform that it has focus

calvfoo14-Nov-07 23:37

hi,

i have a viewer program that will only turn pages when it's in focus.

i've created a capture program to capture the output from this viewer program.
the capture program will be the top most window.
To capture pages from the viewer, I need to capture the viewer's window
and copy the content over to the capture program.

How can i signal to the viewer program that it has focus (so that it turn the pages and
the capture program can capture the new page)?

I was thinking of using FindWindow to find handle to the viewer program.
The I'll use BitBlt to copy the bitmap from the viewer to the capture program.
But, to turn the page, I need to let the viewer know that it's in focus.

thank you.

br,
calvin
