There should only be one default button in a dialog box. Use PUSHBUTTON for 
the rest.

Buttons are windows, so you can send a message to the button to disable it, 
via the EnableWindow function:  EnableWindow(HWND hWnd, BOOL bEnable)
where hWnd is the window handle, and bEnable is set to FALSE to disable the 
window.

Do you have the Win32 SDK?

Re: [Dev-C++] what is wrong with the code

[Per W. <pw...@ia...>]

On one hand, tne lines of code you sent are trivial to look at.

However, it is recommended that you always specify:
- What happens - compiler errors, linker errors, run-time behaviour etc.
- What did you expect to happen.

[Dev-C++] what is wrong with the code

[Dawood V. <da...@ku...>]

	can anybody let me know, why the code below is not running.


#include <iostream.h>
#include <stdlib.h>
#include <string>


int main()
{
   char ch = 'z';
   string p = ch;

   p.push_back(ch);

       system("PAUSE");
       return 0;
}

[Dev-C++] dev C++ producing errors on compiling 'hello world' test;

[Tom H <to...@sc...>]

Hello list,

A quick question;

I downloaded a copy of dev-C++ and opened up the hello world example. It =
looked OK
to me so I did a compile and run without changing anything. But there =
were some compiler
errors which prevented it from finishing.

Any idea what I have done to screw up these include files?
(I've posted the compiler output below;)

Cheers

T.

[Dev-C++] C++ dialog control

Use this header and you should be able to use random() and randomize().

Sorry, there was mistake in this line

      #define random(x)  (rand() % (x))
     //was #define random(x)  (rand() % (x)) +1 )

By the way, when I said "I don´t know", I mean: "There is no delay() or 
similar function in C nor C++ standard library" ;)

Use this header and you could use random() and randomize(). But you 
should get used to the rand() and srand() C standard functions

#ifndef __MY_RANDOM__	
     #define __MY_RANDOM__

     #ifndef _TIME_H_
         #include <time.h>
     #endif

     #ifndef _STDLIB_H_
         #include <stdlib.h>
     #endif

     #define randomize() srand(time(NULL))
     #define random(x)  (rand() % (x)) +1

#endif /* __MY_RANDOM__ */


I don´t know a delay(), but you could use a conio library for Dev-C++.
Here you have one (Spanish link)

RE: [Dev-C++] (no subject)

[P.D. v. Z. <pa...@my...>]

I assume you don't mean a part of the actual program code, but data
entered while running your program. Depending on whether you use C or
C++, you need to either do:

(C code)
FILE* out = fopen("somefilename", "wt");  /* or "wb" for binary files */
fprintf(out, "Blah blah blah");  /* for text files */
fwrite(buf, size_of_buf, number_of_items, out); /* for binary files */
fclose(out);

OR (C++ code):

#include <fstream>

// ....

std::ofstream out("somefile");
out << "Blah blah blah";


Hope this helped,


Paul

P.S.: Specifying a subject next time you ask a question would be nice,
and giving your brain some exercise by searching for things yourself
first would be even better.

Hi...


I have installed this version of DEV-C++ on Win98. I openned Windows =
Explorer and clicked on a C++ file to open it in DEV-C++. The file is =
openned with an error message saying "Cannot find the file 'blah blah' =
(or one of its components)."

The error is harmless because the file is openned successfully but it is =
annoying.

Maybe is your computer the one witch has a virus, so when you try to
install, it gets corrupted by the virus.
Just a chance.

Thank you, Mr. Ricardo, but...

listen for the report:
	A lot of mirror sites reported this problem.
	After post the message, I´ve tried the most distant mirror site:
		C-View.org (China)
	I downloaded it without problems and installed the software!

Are the other sites with an installer corrupted or virus infected?
Or both? Or neither?

Check this line ;)
It happened to me with a game patch. The patch refused to install
because file sizes mismatch. The file had been modified by a virus :(

If it isn´t the problem, try checking your hard drive with chkdsk command.

[Dev-C++] Problems Installing Beta 5

[<and...@su...>]

Dear Users,

   When I try to run the devcpp4980.exe (beta 5), the following
message appears:

"Installer corrupted or incomplete.
This could be the result of a failed download or corruption from
a virus.
If desperate, try the /NCRC command line switch (NOT recommended)"

   I did not try this switch. First I would like to know what is
happening with you, gurus.

ps1: I´ve tried a lot of different mirror sites and the same problem
    still appears.
ps2: WinXp computer

Regards
Andre Barros

Hrmph...

It appears I am a moron and can't manage to reply to the list instead of to
individuals. It would explain a few things... anyways the following to the
list just for reference. If anyone else has problems with DirectInput it
might help them...

Cheers,

MESSAGE 1:

Oo oi,

No more c_dfDIKeyboard errors... and yes I know what SDL is :)
Thanks to all who have offered their input (no pun intended)!

Yeah, I did, but I had to 'borrow' a few lines out of the SDL source. The
only problem you should be having is the linker error involving
c_dfDIKeyboard. Take a look at SDL_dx5video.c, and copy and paste the
definitions in your code. Copy  "static DIOBJECTDATAFORMAT KBD_fmt" and
"const DIDATAFORMAT c_dfDIKeyboard".  Its a whole lot of code, so I won't
paste it in here. Just place it at the end of your source code. You do know
what SDL is ...right?





MESSAGE 2:

Oo oi,

I tried it out and it still gives this problem-

[Linker error] undefined reference to `c_dfDIMouse'

Thanks for the help still!

Cheers,

I copied and pasted from the examples from my book and got something
working. This uses Direct Input to read the mouse. It would take some
more tweaking to get something more useful, but this is something
at least. Assuming you have some basic windows app with menu choices,
pick a menu choice to use and call the 3 functions like this:

initDImouse(MainInstance, hwnd);
readDIMouse(hwnd);
shutDownDImouse();

"MainInstance" is a global I'm using obtained from the HINSTANCE
you get from WinMain. "hwnd" you probably know..
Merge the code below with your app, or put in a separate file (you'll
need to make a header file). The only library I included was
libdinput8.a (and libwinmm.a for something else) and I'm using
DevC++ 4.9.8.0

This all compiles with no problem for me.
