Try this one, it displays four different styles messages, maybe you get the idea of how message boxes work. The last one prompts you with a question.

#include <windows.h>
int main(int argc, char* argv[])
{
	MessageBox(NULL, "Serious error", "<Message title here>", MB_ICONSTOP|MB_SETFOREGROUND);
	MessageBox(NULL, "Warning", "<Message title here>", MB_ICONEXCLAMATION|MB_SETFOREGROUND);
	MessageBox(NULL, "Info", "<Message title here>", MB_ICONINFORMATION|MB_SETFOREGROUND);
	if(IDYES == MessageBox(NULL, "Click Yes or No", 
		"<Message title here>", 
		MB_ICONQUESTION|MB_YESNO|MB_SETFOREGROUND))
	{
		MessageBox(NULL, "You clicked Yes", 
			"<Message title here>", 
			MB_ICONINFORMATION|MB_SETFOREGROUND);
	}
	else
	{
		MessageBox(NULL, "You clicked  No", 
			"<Message title here>", 
			MB_ICONINFORMATION|MB_SETFOREGROUND);
	}
	return 0;
}
