Start with a dialog based app, there is a lot less to follow. Make the OnPain function in the dialog look like this:
if (IsIconic())
{
CPaintDC dc(this);
SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0);
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;
dc.DrawIcon(x, y, m_hIcon);
}
else
{
CPaintDC dc(this);
dc.TextOut(10, 10, "Hello World");
CDialog::OnPaint();
}
I'm not sure if you need the call to the base class, so I left it in, although removing it appears to do no harm. There's your hello world, and the simplest MFC app you'll get outside of using MFC in a console app.

I don't know about everyone, but I always use wizards to begin my projects. They save a lot of time and get me going on the functionality right away. Like yourself, in the beginning I found it a bit hard to follow the generated code, but it was only a matter of time before I became familiar with it.
As far as a little Hello World program, again use the AppWizard to create a "Win32 Console Application". Then tell it you want to support MFC. Presto! See? I told wizards are great.

first i'd like to ask if anyone here is a self taught vc6 programmer. as in no schools just books and stuff like that.
i'm finding that the prices for tuition at any school for a programming course is way out of my budget. i live canada so keep that in mind. next question:
gamedev says to start with a simple tetris like game to understand how a game is put together. i have a book that explains a breakout game and my logic tells me that programming a game like that would be easier then tetris. maybe i'm wrong. anyhoo could someone point me to some source files or code for a tetris like game so i could compare code and possibly understand.
i have to take the self taught book method.

You can teach yourself C++. In fact that's the only way I guess. Even if you have gone for some private course, you'd need to do a lot on your own in the way of self-teaching and books and MSDN and code-project before you can be a moderately competent C++ programmer

I had one basic C++ course in school but for the most part I've learned though books and experience.

Yes, I'm completely self taught and everyone at work, although they went to uni, got there knowing a lot from teaching themself. To survive in IT you need to *keep* learning your entire career, so if you can't teach yourself, you're kinda screwed.
I believe that there is a Tetris game here on CP. Yes, Pong is probably easier still, although not by much. Calculating the bounce of the ball convincingly is probably more painful than figuring if a Tetris block fits in a certain space.
A game is always a big thing to start with though, you need graphics, you need sound, you'll probably want to use DirectDraw, etc. You're better off IMO trying some non game stuff first. To give you an idea, I did a fair bit of non-game stuff to learn and when I did try a game, I was able to do a reasonable Asteroids. Had I started with that, I'd probably have given up in despair, but I kenw how a lot of other stuff fit together so I was able to concentrate on graphics and physics.

I'm a self taught programmer. However I had the easier route of moving from Sinclair Basic, to Turbo Pascal, to Turbo C, to Borland C++ and then onto Visual C++. It is a lot easier if you start at the bottom, sadly that isn't so easy nowadays. I remember my early days of the move from Pascal to C. C was a very scary language to me back then.
My advice, stick with the breakout program. Breakout is a much simplier app than Tetris. However learning to program by writing a game is very difficult, especially a Windows game if DirectX is involved.
Feel free to ask questions though, that is the best way to keep on learning.

If you want to start with C++ start with Sams Teach Yourself C++ in 24 Hours Second Edition. For game programming I would look for a Tearch Yourself DirectX. Another good book that teaches MFC is Teach Yourself Visual C++ 6 in 21 Days. If you can find it look for Game Programming Starter Kit from Macmillan Software 4.0 gives you VC++ in 21 and DX in 24 but 5.0 is the current version. It also has some game programming tools.

You send/post WM_CLOSE to a window when you want to close it. Normally the WM_CLOSE handler then calls DestroyWindow which sends a WM_DESTROY message to the window. later the WM_NCDESTROY message is sent. This is the last message that window receives

I use WM_CLOSE to ask the user if they want to save the document they are working on. If they click cancel I don't call DestroyWindow and the program returns to its previous state. I use WM_DESTROY to release all my resources.

I am creating a utility that does not have a main window. I show different dialogs, one after the other, depending on the situation. It seems the 1st put up dialog gets to be the taskbar button. I would like the next dialog to get its own taskbar button, but I can't figure out how to do it.
Please enlighten me,
Cathy

Thanks, but I already tried that with no luck. I changed it in the .rc file. Was that the correct place?

I want to get the title of Internet Explorer:
#include <windows.h>
LPSTR strIE;
LPSTR str2;
HWND IE;
int WINAPI WinMain(HINSTANCE,HINSTANCE,LPSTR,int)
{
IE = FindWindow("IEFrame",NULL);
if( IE != NULL )
{
GetWindowText(IE, strIE, GetWindowTextLength(IE));
MessageBox(NULL, (LPCTSTR) strIE,"",MB_OK);
}
return 0;
}
But no MessageBox(...) at all will appear! 
What is wrong?

The problem is that your whole app should be exploding. You haven't actually allocated any memory for your string, so the behavior will certainly be unexpected. Try allocating enough space for the string first then calll GetWindowText passing in the amount of space you actually allocated then do the message box then remember to clean up the memory you allocated. A good start would be to learn C/C++ programming before jumping head first into windows development.
Cheers,

Since the IEframe does not belong to your app's process you need to send the WM_GETTEXT message to the hwnd of the IE. This is the correct way:
TCHAR wndText[512];
::SendMessage(IE,WM_GETTEXT,sizeof(wndText)/sizeof(TCHAR),(LPARAM)(void*)wndText);

Hello, the codegurus around the world.;)
I think that your approaches works to get the text in Edit box as
Paul Delicika sais in MSDN artile. 
The following code works for me.
void CCodeTestDlg::OnOK()
{
CString ieTitle;
TCHAR title[MAX_PATH];
CWnd *pWnd = CWnd::FindWindow ("IEFrame",NULL);
if (pWnd) {
MessageBox ("IE is opened!", "Info");
pWnd->GetWindowText (ieTitle);
GetDlgItem (IDC_MYSTATIC)->SetWindowText (ieTitle);
::GetWindowText (pWnd->m_hWnd, title, MAX_PATH);
MessageBox (title, "Test");
}
else {
MessageBox ("IE isn't opened!", "Info");
}
}
Please, don't send me your email about your questions directly.
Have a nice day!

Hi All!
under MS Visual Studio, we have a tool call Package Deployment Wizard for Visual Basic. This tool helps make a setup package for an EXE file of VB. It attaches all the dll files to the VB exe file basically. Do we have anything like that for VC++? I ask this because one of my applications does not run under NT4.0 SP6 when I compile it using "use MFC in a shared dll". The file needed is MFC42.dll;
Thanks

There is InstallShield for this.

Hi!
I use install shield to make setup disk. However, the installed package does not fix the problem. The OS still complains about the MFC42.dll
Do I miss anything?
Thanks

VC++ 7 has a built-in setup feature, that should be enough for most deployment needs.

I have to detect if there is a RAS connection active on the machine, so I wrote the following code
RASCONN * lpRasConn;
DWORD lpcb;
DWORD lpcConnections;
lpRasConn = (LPRASCONN) GlobalAlloc(GPTR, sizeof(RASCONN));
lpRasConn->dwSize = sizeof(RASCONN);
lpcb = sizeof(RASCONN);
int nRet = RasEnumConnections(lpRasConn, &lpcb, &lpcConnections);
if (nRet != 0)
{
TRACE("RasEnumConnections failed: Error = %d", nRet);
return(FALSE);
}
else
{
TRACE("The following RAS connections are currently active\n\n");
return(TRUE);
for (DWORD i = 0; i < lpcConnections; i++)
{
TRACE("Entry name: %s\n", lpRasConn->szEntryName);
lpRasConn++;
}
return(TRUE);
}
The fuction fails everytime and I always have the same error message (even I test it on different computers)
the message is "632 : The structure size is incorrect".
Any help would be great..
Thanks,
Fakhri

Hello, the codegurus aroudn the world.;)
This is the latest RASCONN struct.
typedef struct _RASCONN {
DWORD dwSize;
HRASCONN hrasconn;
TCHAR szEntryName[RAS_MaxEntryName + 1];
#if (WINVER >= 0x400)
TCHAR szDeviceType[ RAS_MaxDeviceType + 1 ];
TCHAR szDeviceName[ RAS_MaxDeviceName + 1 ];
#endif
#if (WINVER >= 0x401)
TCHAR szPhonebook [ MAX_PATH ];
DWORD dwSubEntry;
#endif
#if (WINVER >= 0x500)
GUID guidEntry;
#endif
#if (WINVER >= 0x501)
DWORD dwSessionId;
DWORD dwFlags;
LUID luid;
#endif
} RASCONN ;
So, if we didn't download the latest Microsoft SDK, and didn't get the ras.h file, RASCONN struct size may be conflicted in rasapi32.dll in OS.
To avoid this kind of the conflict, you may be better explicit intialization of RASCONN struct in your code. Otherwise, you had better install the latest Microsoft SDK.
However, this is my guess. 
Please, don't send me your email about your questions directly.
Have a nice day!
