Thread: Mouse Event

Just trying to handle a simple left-click. Code doesn't work. Tried everything.

Code:

#include<iostream>
#include<cstdlib>
#include<cstring>
#include<windows.h>
using namespace std;

#define WHITE  BACKGROUND_RED|BACKGROUND_GREEN|BACKGROUND_BLUE|BACKGROUND_INTENSITY
#define RED    FOREGROUND_RED|FOREGROUND_INTENSITY	
#define BLACK  0

typedef struct card
{
	unsigned int face_value;
	char suit;
	card *next;

	card(){next=NULL;}
 
}*mycard;


void gotoxy(int x, int y);
void paint_cards(HANDLE, card*);


int main()
{
    system("cls");

    HANDLE hIn;
    HANDLE hOut;
   
    int LoopCount = 0;
    int KeyEvents = 0;
    INPUT_RECORD InRec;
    DWORD NumRead;

	hIn  = GetStdHandle(STD_INPUT_HANDLE );
	hOut = GetStdHandle(STD_OUTPUT_HANDLE);
	

	mycard new_card = new card;

	srand(GetTickCount());

	system("color 20");
	
	paint_cards(hOut, new_card);


    for(;;)
    {
	ReadConsoleInput(hIn, &InRec, 1, &NumRead);

		if (InRec.EventType == MOUSE_EVENT)            

			if (InRec.Event.MouseEvent.dwEventFlags == 0)                
                
                               if (InRec.Event.MouseEvent.dwButtonState & 0x01)
                               {  
					system("color 70");
					system("cls");
					cout << "\a\tIt works!!";						
		               } 
     }
 

    return 0;
}


void paint_cards(HANDLE hOut, card* new_card)
{
	int cx=5, cy=5;

	for(;cx<46;cx+=10)
	{
		
		new_card->face_value = static_cast<unsigned>(rand()%8+2);

		new_card->suit = static_cast<char>(rand()%4+3);	

		SetConsoleTextAttribute(hOut, new_card->suit<5?WHITE|RED:WHITE|BLACK);

		gotoxy(cx, cy+0);	cout << endl << endl << endl;
		gotoxy(cx, cy+1);	cout << new_card->face_value	<< new_card->suit << "   \n";
		gotoxy(cx, cy+2);	cout << "     \n"; 
		gotoxy(cx, cy+3);	cout << "  "  << new_card->suit << "  \n";
		gotoxy(cx, cy+4);	cout << "     \n"; 
		gotoxy(cx, cy+5);	cout << "   " << new_card->suit << new_card->face_value;
		gotoxy(cx, cy+6);	cout << endl  << endl  << endl  << endl;	

		new_card = new card;

	}

	SetConsoleTextAttribute(hOut, WHITE|BLACK);

	gotoxy(10, 16);		cout << "         "; 
	gotoxy(10, 17);		cout << " Hit Me! ";
	gotoxy(10, 18);         cout << "         ";

	cout << endl << endl << endl;
}



void gotoxy(int x, int y)
{
  COORD coord;
  coord.X = x;
  coord.Y = y;
  SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);

you code seems fine
Check the return value of the ReadConsoleInput(). and see what GetLastError() returns

You know.. It was those pesky system( ) calls..!! For some reason, they screw everything up..! and when I took them out.. code works perfect..!!!

(i was just using system() as a cheap and easy solution until i got the program done.. and then go back and optimize/make more c++ standard compiant)
