Huh? 
You're going to use the MFC CFile class instead of the .NET file classes?
If so, the solution is exacly the same.
The CFile class "provides unbuffered, binary disk input/output services".
So my answer would be the same - CStdioFile is probably a better choice if you're working with text
files. If the files are binary with embedded text, you'll probably need to search for the text yourself.

Hi,
I am connecting a device through GPRS, using SLIP. But that doesn't work. (if you can help here, ok) so I need to change the protocol from SLIP to PPP.
So does anybody know the bare minimum PPP protocol implementatation, bare minimum just to send and receive. In C?
Thank you very much.

You voted a one for the last reply you got in this forum so I am reluctant to offer you assistance. This forum is not for C/C++ questions. This forum is for C++ development on the .NET platform using the Microsoft CLI extensions to C++. C and C++ questions belong in the Visual C++ / MFC forum.

What does "doesn't work" mean?

Are you asking about developing your own PPP stack? I wouldn't think that has been done any longer after like Windows 95 and 2000 since the OS's provide those stacks.

Yeah I see what you mean. I did give him a second opportunity to show he isn't a giant jackass but he wasn't able to accomplish that task I see. This seems to prove, not that I needed proof, Windows isn't the only platform suffering from the attack of the monkey developers.

hehe I haven't seen enough of it yet to guess but I'm suspicious of any number of the Soapbox wack jobs we have in there. But the more obvious conclusion is that it's my charming teddy bear personality.

I suspect it involves more literacy than you seem to be bringing to the equation.

hi
how to get message from other window such as OnMessage in Mfc

In a form? If so, maybe override WndProc().

#define WM_MESSAGE WM_USER+1000<br />
ON_MESSAGE(WM_MESSAGE,Function)<br />
but i don't know how to create in vc.net

As Mark said, override WndProc() to react on specific messages. Here is a C# example:
protected override void WndProc(ref Message m) {
if (m.Msg==LPWIN_Constants.WM_HOTKEY) {
int lParam=(int)m.LParam;
if (lParam==0x00580003) Activate();
if (lParam==0x00410008) ArchiveWindow();
}

Using Events is also another option for notifying another window.

Hello, everyone. I am designing an application that is intended for use with a touch-screen monitor, so all of the GUI elements need to be big, friendly, and easy to poke.
I would like to provide context-sensitive help for various controls on the main form, and thought that I might just watch for the WM_HELP message that is sent whenever a control is clicked on when in "What's This?" mode, entered by clicking the "?" help button on the title bar. That bit works fine, but I am running into an unexpected problem.
Since the "?" button is much too small for my touch-screen requirements, I thought that I would include a larger help button elsewhere on the form that would accomplish the same thing. I have been totally unable to find any way to programmatically trigger "What's This?" mode, though. The "?" button doesn't even seem to send a message to WndProc() when it is clicked. Does anyone know what occurs when this button is clicked, and how to accomplish the same thing programmatically?
If not, does anyone have any suggestions for providing context-sensitive help that doesn't require something silly, like putting a check in the form of if(helpMode) { ShowHelpMessage(this); return; } at the start of the click event for every single control?
Thanks very much!

I don't know but I would not think that at all. If I needed to know I would start here[^].

Mike,
Thank you for the suggestion, but you really did not address my question. As I stated, I am recognizing when a user clicks on a control when in "What's This?" mode with no problems. Everything works great if the user can click the help ("?") button in the title bar and then on another control. Since my requirements are that a touchscreen be used for the interface, however, I need to create a larger button that operates like the titlebar help button.
I am unable to enter "What's This?" mode programmatically. That is what I was asking about. I've searched all over, including in reference books, with no results, and thought that I'd seek expert experience as a last resort. Respectfully, directing me to Google with a search phrase that general is insulting.

Yes it is, to me since I obviously did not read your post thoroughly. I apologize for that but I was not trying to insult you.

Ok, I read your OP again and this several times. Since you are on a touch screen you wan the user to click once on your button and then a second time on the control to kick off Context Sensitive Help yes? If that's correct then I don't know if this will help you but the '?' button sends a WM_SYSCOMMAND message.[^]

Mike,
I apologize for not responding sooner, but I was a victim of whatever happened to the boards yesterday, and couldn't log in. Sorry for getting snippy back there, too. I should know better than to check up on message boards when my day isn't going well to begin with. I suppose I could have made my OP a little more clear, too.
In any event, the WM_SYSCOMMAND message sounds like exactly what I need. I came to the conclusion before that the "?" button was not sending a message by trying to watch the behavior of the WndProc method when it was pressed. With how many messages go through that puppy, I missed it.
I've been playing around with Win32 messaging since yesterday, which is new to me, and I can't quite seem to get this rolling. Perhaps you could shed some more light on this for me? I believe that this is the last part of the solution to my problem. I've cobbled together the following lines in a button click handler to attempt to activate "What's This?" mode:
int WM_SYSCOMMAND = 0x112;
IntPtr SC_CONTEXTHELP = IntPtr(0xF180);
Windows::Forms::Message msg = Windows::Forms::Message::Create(this->Handle, WM_SYSCOMMAND, SC_CONTEXTHELP, IntPtr(0));
this->WndProc(msg);
It compiles without complaint, but nothing happens (that I can detect, anyway) when the button is clicked. Can you see what I am screwing up or missing?
Thanks for your patience, and I appreciate the help.
