Message Box in C

[neeludhiman]

Hi friends,
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.

Hi sunnypalsingh,
Thank you very much for your kind attention and reply to my query. 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 ?
Thanks a lot.

You should mention such requirements with original question.

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

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);
