Thanks For Reply.

As you told me to read the content as linked in your reply, I read it very carefully.

And I got one confusion that In this content I found the below line.........

If you redistribute an MFC DLL, be sure you redistribute the retail version rather than the debug version. Debug versions of the DLLs are not redistributable. Debug versions of the MFC DLLs have a trailing "d" in their file names, as in Mfc80d.dll.

Here how can I redistribute my ocx of the retail version not debug version.And where this retail version is on my system. Sorry for the such silly quetions but I have no idea about this retail version.

can you suggest me something more?

Thanks.

Hi Ashish,

Retail version means release build. You have to build your OCX in release configuration. Release build does not have debug information.

Please read http://msdn2.microsoft.com/en-us/library/ms889184.aspx for more information.

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

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.

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.
