Here's one with 10 lines of code:
if (argc < 4) return (1);
CFile file(argv[1], CFile::modeRead);<br />
CString Buffer;<br />
file.Read(Buffer.GetBuffer(file.GetLength()), file.GetLength());<br />
Buffer.ReleaseBuffer(file.GetLength());<br />
file.Close();<br />
Buffer.Replace(argv[2],argv[3]);<br />
file.Open(argv[1], CFile::modeCreate|CFile::modeWrite);<br />
file.Write((LPCTSTR)Buffer, Buffer.GetLength());<br />
file.Close();<br />

Cool thanks, I think I'll use that. Although I may de-MFCify it to make the app more lightweight.

I don't know what the problem may be, but have you hovered over the IDS_SOMESTRINGID to see what its value is? Also make sure you don't have a resource defined with the same id.

I have a worker thread and need to start and stop a timer.
As I understand there are two ways to do this, using CWnd class and handling OnTimer()or SetTimer(hWnd, ....) API call, but both rely on having a UI to receive WM_TIMER messages. Is this correct? 
If yes what is the best way to implement a timer in a worker thread, that does not interact with the UI at all?

Very Much Correct ,No problem using timer in UI

You have to use Sleep api to simulate the Timer in worker thread.

Look at CreateWaitableTimer and use WaitForSingleObject or else WaitForMultipleObjects, if you have another event or such to signal your thread to exit or to perform some other work.
Instead of using Sleep() os LeepEx() which will lock up your thread until the sleep has timed out.

There are two ways to use the SetTimer API. The first is as you said where you specify an HWND that will recieve the WM_TIMER message. The second is to use the CALLBACK function that you specify in the fourth parameter of the SetTimer() function. See SetTimer[^] and TimerProc[^] in MSDN for more info.

You do not have to have a window to create a timer. You can create a timer if you supply NULL for the hWnd and supply a callback proc.

Is there a simple way to disable only the menubar ( and toolbar ) of the main frame of an MDI application ? while keeping a couple of them available ( like "quit" ).
I have an operation that, when run, needs to diable some operations, while keeping the different views active.
I could have ON_UPDATE_COMMAND_UI handlers for all menu commands that will check a state variable, but that will mean a lot of code change, but on the other hand it's failsafe.
Thanks.

That's the recommended approach. I don't think this will require a lot of code changes. Code addition maybe, but no modifications.

Have a look at ON_UPDATE_COMMAND_UI_RANGE. This will allow you to create a single function to handle enabling/disabling of an entire range of IDs.

This needs to have a sequentially continuous ID range; which is something I cannot be sure of.
I will go with the other suggestion, add one ON_UPDATE_COMMAND_UI for each menu item; luckilly, all my commands are in a couple files.

What exactly do you want ?
Can't you create your own ? Can't you download any of Code Project samples and examples ? or any of Microsoft samples ?

I'm writing a utility which uses files which reside on a network drive. In order for the application to run correctly the first time, the user must (outside of my application) open up the network drive in Windows Explorer to authenticate.
In my application, if the user is not authenticated, fopen(), etc just returns false citing improper access or whatever. Is there a way I can force windows to display the authenticate dialog before failing at fopen()?
Its a standard win32 app...
Thanks.
Mike.

While I've not ever tried it in this context, do NetShareAdd(), CreateProcessAsUser(), or NetUseAdd() help?
