Using window dll

[magic]

Hi, can someone write me a code to use window MessageBoxA()
Just write a code display "Hi there" using window dll MessageBoxA()
I really confuse how to import dll staticlly.

Thanks

this is my code(not working)

Code: [Select]

int __cdecl MessageBoxA(int a,char *s1,char *s2,int b);

#include <stdio.h>

/* entry point */
int main(void)
{
MessageBoxA(0,"Hi there","Hi there",0);
    return 0;
}

MessageBoxA is __stdcall not __cdecl but you don't need to know that. Include the right header file and library and the import is done for you.

Code: [Select]

//int __cdecl MessageBoxA(int a,char *s1,char *s2,int b);

#include <windows.h>
#include <stdio.h>

/* entry point */
int main(void)
{
MessageBoxA(0,"Hi there","Hi there",0);
    return 0;
}

You do not need to use MessageBoxA, MessageBox will do, the header file will decide which version to use, ANSI or UNICODE, based on the setting of a variable.
Check the Windows header for the variables name.
