Thanks alot guys,

the comments are very useful.

Tim, are you saying a BOOL type variable can be more than just TRUE (1) and FALSE (0) ?

actually, yes. But I've not seen any app setting the value of a BOOL to anything other apart from TRUE and FALSE.

TRUE is just a #define (1), while FALSE is a #define (0)

Don;t be too sure about it... TrackPopupMenu return BOOL and it can be made to return which menu item was selected in the popup menu (setting via parameters).

Thanks; that's why I said "I haven't seen any app....". Now I know there IS at least one API doing such things Smile | :)

The WIN32 API is a bit of a minefield when it comes to BOOL processing. On NT the API might return a true TRUE/FALSE while on Win9x, then API might return ==0/!=0. This is why I always say to play it safe and never test for "== TRUE".

if your BOOL > 0 it is TRUE.
if your BOOL = 0 it is FALSE.
Don't know for sure for values < 0.

their are apps eg. where your BOOL has value 2 or 3 , ...
then you can do if(YOURBOOL){ ... }

personally I think BOOL is against the whole idea of the basic datatype of a boolean. I would recommend a bool if you want to use true or false and an int or something if you have more values (and do if(yourint == 3){...})
but it's MFC Unsure | :~

it is

BOOL == 0 is FALSE
BOOL != 0 is TRUE

Using MFC in Win32 Application

Hi Everybody,

I have a question regarding "Using MFC in Win32 Application". I am using Visual Studio6.0. I want to use MFC in my Win32 Application. I started File->New->Win32 Application->A Simple Win32 Application. And I get the following code pasted below. Now I want to use MFC, say, CString, How do I do it? I tried to use as "CString str" and included the header file <afx.h> but of no use. It gives compile errors as "CString undeclared identifier" Can anybody help? Can anybody tell me which header files and .lib files to use, or any other settings to be made to the editor???

----------------------------------------------------------
// FirstSample.cpp : Defines the entry point
// for the application.
//

#include "stdafx.h"

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
// TODO: Place code here.
CString str;
return 0;
}
-----------------------------------------------------------

after:
am using Visual Studio6.0. I want to use MFC in my Win32 Application. I started File->New->Win32 Application->A Simple Win32 Application. And I get the following code pasted below.
click the "Project" menu
then choose Settings.
In the "General" tab you will see that you project ins't currrently using MFC. You can choose to use MFC in a static LIBRARY or in a DLL. I f you choose to have it in a library you'll have to include these files in stdafx.h
:
#include <afxwin.h> // MFC core and standard components
#include <afxext.h> // MFC extensions
#include <afxdisp.h> // MFC Automation classes
#include <afxdtctl.h> // MFC support for Internet Explorer 4 #include #include <afxcmn.h> // MFC support for Windows Common

I haven't used MFC in a dll and I don't know if you have to include them there but i know that you won't have to carry all those DLL's if you want to check your app on a computer without VC++ installed

problem with console app

here is a relevent snippets:

TCHAR buf[20]; 

fdwMode = ENABLE_LINE_INPUT |       //ReadConsole() should wait and read 
                                   // characters until ENTER is pressed 
                 ENABLE_ECHO_INPUT |   // show characters as you type 
                 ENABLE_PROCESSED_INPUT;    // let system process all 
                                                // control keystrikes 
SetConsoleMode(hStdin, fdwMode) ; 
        
fdwMode = ENABLE_PROCESSED_OUTPUT; 
SetConsoleMode(hStdout, fdwMode); 


while (1) 
{ 
    WriteConsole(hStdout, "\npress [1] for codepage: ", 25, &ch, NULL); 
     ReadConsole(hStdin,buf,1,&ch,NULL); 
     buf[ch]='\0'; 
     FlushConsoleInputBuffer(hStdin); 
    WriteConsole(hStdout, buf, 3, &ch, NULL); 
}

the problem is that the first time while executes everything is ok:
i get on screen:

press [1] for codepage:

i enter 1 and press enter then it prints the character.

from this point something strange happens...
while loop continue to execute two more times despite the fact that ReadConsole() should wait for input...

anyone understand where is the problem?

Considering you only request one char, and '1' + CR + LF is three chars...

but i using FlushConsoleInputBuffer() after call to ReadConsole()

and i using also ENABLE_PROCESSED_INPUT flag. the documantation says that in this case system processes the control keys and doesn't put them to input buffer

Hi.
I am trying, unsuccessing, to operate the outp command in C++ (Visual Studio
Ver 6.0) through the address of the printer.

I have an OS windows XP.

I wrote: "outp(0x378,0x24);" trying to operate the LPT1 address, and nothing
happened.

Please, show me how to do it rigth.

Thank you.

Hi all,
I would like to open a dialog box from a console application. Basically, I have an app that looks for new processes and if certain processes appear I want to pop up a dialog box.
Any pointers to tutorials, articles, sample code would be appreciated.

You may want to instead consider building a standard Windows app that runs in the system tray a la anti-virus, firewall and similar daemon apps.

It can list all the running processes. From the list search for the process you are looking for.

CString into a non-MFC app

Hi,
I'd like to use a XML parsing library (http://www.codeproject.com/soap/markupclass.asp) that uses CString (I guess that's the only MFC thing it uses). I'd like to use it in a pure WinAPI app, is there a way to add CString there Confused | :confused:

? (which files/libs to link, never worked with MFC really). An alternate solution would be another XML library.

Thanks for your answers
