Can anyone tell me how can we get message boxes (e.g, with buttons OK, Cancel) in C ?
Please guide.
Thanks,

Try this sample code

#include<windows.h>
int main()
{
MessageBox(0,"Hello","Welcome Message",1);
return 0;
}

Change the last parameter to see various options.

This code will work fine with Windows. But I am working in Linux. In Linux, can you please tell me if there is an option to get this dialog box without GTK ?

You should mention such requirements with original question.

I have no idea of linux. Maybe someone …

I have no idea of linux. Maybe someone else can help you out in this.

Its not as easily accomplished in *nix -- you have to do lots and lots of programming to get that to work in graphics mode. Motif open source package helps a little. Or you might use console-based curses library functions.

Well, without gtk and without writing lots of code after becoming an expert of X programming, you could use xmessage which is included in almost every distro... It's not an elegant way to do what you want, but it's easy and it works. For more info: man xmessage

Anyway here is an example of a MsgBox portable in win & linux

#include <stdio.h>
#include <stdlib.h>

#if defined(WIN32) || defined(WINDOWS)

#include <windows.h>

void MsgBox(char *s){
    MessageBox(0, s, "Message", 1);
}

#else

#include <unistd.h>

void MsgBox(char *s){
    char cmd[1024];
    sprintf(cmd, "xmessage -center \"%s\"", s);
    if(fork()==0){
        close(1); close(2);
        system(cmd);
        exit(0);
    }
}

#endif

Sudo: did you notice that you answered a year-old thread?? :mrgreen: :mrgreen:

2 years after your reply: dragon, I'm glad he did answer - it's a nice solution for my problem :-)

This is what worked for me in Visual Studio:-
MessageBox(NULL,(LPCWSTR)L"Hello",(LPCWSTR)L"Welcome Message",MB_OK);
