The taskbar enumerates only windows with the WS_EX_APPWINDOW and WS_VISIBLE 
styles. The title is the window's text (GetWindowTextLength - warning! some 
window classes return bogus values for this, always mask out the higher 16 
bit - and GetWindowText). The icon is either the window's icon 
(WM_GETICON), the class's icon (GetClassLongEx), or a default icon of your 
choice

ok! here I go again...

Ive tried to use EnumWindows, but i did not get what I expected. I expected to get the running applications on the desktop and the ones on the system tray. But instead, I got more that 100+ windows that where enumerated by the function. Maybe I must be more General but specific in the problem.

How do I create or code a program, that would detect, name, and switch between running applications just like windows explorer does(windows taskbar)? How do I create such an application? What functions will I use?

Thanks to anyone

How do I access assembly routines in Dev-C++ ?

argv is an array of C-string pointers which has stored the arguments
given in command line. argv[0] is the name of the program itself. argc
is the number of argv elements and is at least 1 (the name of the
executable). **argv is also *argv[]. The second is the more notationally
correct (because argv is an array of c-strings). So here is some ANSI
C++ 1998 code demonstrating this:
=20
=20
#include <iostream>
#include <cstdio>
=20
int main(int argc, char *argv[])
{
     using namespace std;
    =20
     cout<<"The total number of arguments including the filename of the
program,\nargc: "<<argc<<endl;
    =20
     cout<<"\nAnd now the arguments only:\n";
    =20
     for(int i=3D1; i<argc; i++)
        cout<<argv[i]<<" ";
       =20
     cout<<endl;
    =20
     getchar();
}

=20
How i executed it:
=20
C:\c>temp 1 test
The total number of arguments including the filename of the program,
argc: 3
=20
And now the arguments only:
1 test
=20
=20
=20
Hope you got it.

I have found a really good site for C++ tutorials.  It is a web edition of 
an old book called Teach Yourself C++ in 21 days.  It's link is at 
http://members.tripod.com/~firstpod/cpp21/index.htm.

Over the 21 days it will teach you structures, streams, templates, quite a 
lot.  I found it all compiles in Dev up to chapter 18, but I'm having some 
trouble with streams in 19.

Hope this helps all you newbies.

You appear to not understand what argc and argv are. They are a standard =
part of a C/C++ program with a main() function and are linked together =
in thier use. When you execute a program and follow it with various =
parameters, i.e.:

MyProg -a 20 -b MyFile.foo

then the OS breaks the string down into each of the individual words =
(seperated by spaces (usuualy)) and uses both argc and argv together to =
make them accessible to the program. The first argc is pretty simple, it =
gives you the number of arguments passed to your program including the =
string representing the executable command. So in the above example argc =
would be 5. Note it depends on the OS as to how the command is broken =
down (AFAIK), but usualy spaces are it, possibly with commands enclosed =
in qoutes treated as one command and kept whole.

The second argv is a little more complex. I hope you are OK with =
pointers, because we are dealing with a pointer, to a pointer, to a =
string. Or if you prefer an array of pointers to strings. Basically you =
have an array of values that point to all the command strings passed. =
The OS doesn't convert numbers for you (as you seem to think) it just =
passes everything as strings. The above command would translate into:

"MyProg", "-a", "20", "-b", "MyFile.foo"

If you wanted to display the name of the program then you could use:

cout << argv[0];

or

cout << *argv;

The array version is used more often as it is easier to understand when =
seen. The fifth argument could be displayed with:

cout << argv[4];

Displaying: MyFile.foo

Using this method the OS can allow any kinds of arguments to be passed =
into a program without worrying about what is right or wrong. It leaves =
it up to you, the programmer, to detect right and wrong.

Here is a simple example (untested):

// Add.exe

#include <iostream>
#include <cstdlib>
#include <cctype>

int main(int argc, char *argv[])
{
    // make sure enough args supplied
    if(argc !=3D 3)
    {
        cout << "Usage: " << argv[0] << " A B" << endl;
        cout << "Where A and B are integers" << endl;
        exit(1);
    }

    // make sure both values are integers
    char *pch;
    // first arg
    for(pch =3D argv[1]; pch; ++pch)
    {
        if(!isdigit(*pch))
        {
            cout << "Values must be integers!" << endl;
            exit(2);
        }
    }
    // second arg
    for(pch =3D argv[2]; pch; ++pch)
    {
        if(!isdigit(*pch))
        {
            cout << "Values must be integers!" << endl;
            exit(2);
        }
    }

    // add the numbers together and output
    cout << argv[1] << " + " << argv[2] << " =3D ";
    cout << atoi(argv[1]) + atoi(argv[2]) << endl;
   =20
    return 0; // all ok
}

Try compiling that, correct any syntax or other errors I may have made, =
and it should when executed from a dos prompt output the sum of the two =
digits supplied.

If you are a newbie then I don't expect you to understand all that I did =
in that. I'm a bit lazy and didn't want to write it in a way that was =
easier to read to someone not used to pointers etc... (I hope it works =
now).

I hope this helps, Jason.

PS: when I say strings I was refering to the C style of null terminated =
array of chars, and not the container class in C++.

Hi,
I am trying to use DEV C++ 4.0. I have already build some API Routines for
Visual FoxPro 5.0 using their construction Kit. Construction Kit Contains a
header file "PRO_EXT.H". Link Library APIMSOBJ.LIB. To Compile these
routines I used VC++6.0. This works fine. But when I tried the same program
in DEV C++ 4.0 it returns many errors. Please help me.

 Hi!

 Does anyone knows tutorial on the WEB, or could me explain, how to 
use files in C++. In the books and tutorials information are only 
about text files, something like:

 ofstream myFile("file.txt");
 myFile << "Some text";

 But how to store/read structured data in files? In Turbo Pascal it 
looks like:

  { Creating a record }
  type human=record
         name:string;
          age:integer;
     end;

  var myFile:file of human; {file for storing records "human" type }
	person:human;

  person.name := "GreatName";
  person.age := 100;

  assign(myFile, 'peoples.hhh');  
  rewrite(myFile);
  write(myFile, person);

  { and so on .. }   
 
 How to do the same in C++ ?? 

 Thanks!

Hi,

is there a rule concering html in here ?

some of the user's mails (html) do appear crippled here
(does not happen with other html mails from other sources)

html also appears to be vulnerable by viri - 

???

Here is another solution, based on what Mr. Graeme suggested.

To build the binary file, untar the archive and type "make" from the 
command line.

Hi, I'm Mario from Argentina and I wrote to you last
Monday about a problem on Dev-C++.

Here's what happened:

1) After I sent the mail to you, I realised that there was an update
    available (4.01). So I downloaded it and replaced the old
    DevCpp.exe for the new one... but the error persisted.

2) Then I took a look into my C++ program and try to understand
    why I got the compiler error while my friend (who also works
    with Dev-C++) didn't.
    And there they were: I placed two comments (or remarks if
    you like) starting with "//" BEFORE the inclusion of the
    libraries.

3) I cut'em and pasted'em UNDER "#include <iostream.h>" and
    "#include <stdlib.h>"... but the compiler error persisted.

4) Then I noticed that the cursor wasn't at the top-left corner of
    the editor, and I thought to myself: "It may be an edition
    problem".

5) So I pressed Ctrl+Home to re-position the cursor and clicked
    on the "Compile project" button...
    ALL WAS JUST FINE! NO ERRORS, AND MY EXE FILE
    WAS CREATED.

So I came to a conclusion:

- YOU CAN'T PUT ANY REMARKS BEFORE THE INCLUSION
  OF THE LIBRARIES.

- YOU MUST POSITION THE CURSOR IN THE TOP-LEFT
  CORNER OF THE SCREEN BEFORE COMPILING.

These considerations stand for Dev-Pascal as well.

I hope you'll fix this in your next updates, 'cause Dev-C++ and
Dev-Pascal RULE! Thanx.

cprintf is declared in conio.h for Win32 console programs (non-Ansi,
non-Unix)
Usually outputs direct to video memory.

Unlike fprintf and printf, cprintf does not translate linefeed characters
(\n) into carriage-return/linefeed character pairs (\r\n). Tab characters
(specified by \t) are not expanded into spaces.

(This information is from Borland help files.)

following.

int STDCALL
WinMain (HINSTANCE hInst, HINSTANCE hPrev, LPSTR lpCmd, int nShow)

There are advantages and disadvantages to both. printf() is fast =
flexible and usable in c. It has the advantage that the library for =
<stdio.h> is smaller than the equivalent C++ <iostream> so in theory you =
could make smaller apps with it.

However in C++ you can create objects that have stream operators =
associated with them, which allows for a cleaner interfaces most of the =
time. Which makes it easier to output loads of data in an object, i.e =
cout << MyObject; as opposed to printf("Var A: %d, Var B: %s, etc...", =
MyObject.A, MyObject.B, etc...);

In general printf has more in common with other languages such as =
Pascal, and therefore the structured approach. In cout you don't need to =
remember any %letter combinations, as the compiler handles it all for =
you. You can use whatever suits your needs.

In the end the output is directed at STDOUT (or something similar) for =
both.

As for cprintf, does it take the same form as standard printf? It may be =
a dedicated version for a specific implementation, or it only works with =
certain values. I know that standard C does supply a few other printf =
functions i.e. vprintf (I think), but I've never really looked into =
them.
