if every one can buy a book and get the solution from there then why do we need a forum like this?

CCommandLineInfo cmdInfo;
ParseCommandLine (cmdInfo);
use CWinApp::ParseCommandLine to initialize a CCommandLineInfo object with values reflecting the parameters entered on the command line, which often include a document file name. The statements
if (!ProcessShellCommand (cmdInfo))
return FALSE;
"process" the command line parameters. Among other things, ProcessShellCommand calls CWinApp::OnFileNew to start the application with an empty document if no file name was entered on the command line, or CWinApp::OpenDocumentFile to load a document if a document name was specified. It's during this phase of the program's execution that the framework creates the document, frame window, and view objects using the information stored in the document template. (In case you're wondering, the document object is created first, followed by the frame window and then the view.) ProcessShellCommand returns TRUE if the initialization succeeds and FALSE if it doesn't. If initialization is successful, the statements

A handy reference is MFC Internals[^]. It's got a lot more concrete information on how the framework is put together and how it works. I didn't feel I understood MFC until I read this.
The book is a little out of date now, having originally been written for MFC 4.0, but the fundamental operation of the framework barely changed from MFC 4.0 to 6.0 (indeed, versions 4.2, 5.0 and 6.0 were upwards-compatible in binary form - a program built with 4.2 could typically run unchanged on MFC 6.0's mfc42.dll). 7.x has had more changes to accommodate the merging of ATL and MFC.

Hi !!!
this is what I have been working on
hdc = BeginPaint(hWnd, &ps);
hdc = GetDC(hWnd);
hbitmap = (HBITMAP)LoadImage(NULL,szFileName,IMAGE_BITMAP,0,0,LR_DEFAULTSIZE|LR_LOADFROMFILE);
if(hbitmap==NULL)
MessageBox(hWnd,"coudnt load ", "error ", MB_OK);
break;
// this doesnt return NULL , so the image is getting loaded properly ????
HDC hdcMem = CreateCompatibleDC(hdc);
GetObject(hbitmap ,sizeof(bmp), &bmp);
SelectObject(hdcMem, hbitmap);
BitBlt(hdc, 0, 0, bmp.bmWidth, bmp.bmHeight, hdcMem, 0, 0, SRCCOPY);
DeleteDC(hdcMem);
EndPaint(hWnd, &ps);
it would be great if you could help me out with this. thanx in advance !!!

Rest everything looks fine.

Why is the item of "IDR_***TYPE" more than "IDR_MAIN_FRAME"?
|
|
|
|
|
when our application is SDI,in working region ,in menu resource of resource,
there is only a "IDR_MAINFRAME",but if your application id MDI,this time,
you can find "IDR_MAINFRAME"and "IDR_****TYPE",then in app.cpp correspondingly,you will see when SDI,
pDocTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(C***Doc),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
RUNTIME_CLASS(C****View));
AddDocTemplate(pDocTemplate);
but when MDI,
pDocTemplate = new CMultiDocTemplate(
IDR_***TYPE,
RUNTIME_CLASS(C***Doc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame
RUNTIME_CLASS(C***View));
AddDocTemplate(pDocTemplate);
IDR_MAINFRAME is for matching with mainframe,IDR_***TYPE is for matching with ChildFrame,but only when MDI there is ChildFrame  ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Where can i get info about the timer capable of running in 10 ms(not MMtimer)
|
|
|
|
|
have a look at OnTimer()/KillTimer() function in the MSDN...
boring...

OnTimer() is limited to 55 milliseconds regardless of the time-out value you set, so this will not work.
http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/dnargame/html/msdn_dos2win.asp
The Multimedia Timer. The multimedia extensions to Windows include a high-resolution timer, invoked with timeSetEvent, that has a resolution of 1 millisecond. Besides having this higher resolution, the timer can produce more accurate results because it does not rely on WM_TIMER messages sent through the queue.
In fact, each multimedia timer is put in its own thread, and the callback function is invoked directly regardless of any pending messages or other things that may be going on. That's an important point, because it means you have to be careful about accessing global data—a variable could be changed by your timed procedure, for example, just as some other function called in the normal message-processing loop is using that data. If you do set up a multimedia timer, make sure you understand about synchronization, semaphores, and all the other apparatus of multithread programming. (Schildt [see bibliography] gives a good overview.)
To use timeSetEvent you must include MMSYSTEM.H and link in WINMM.LIB.
