Setting the Cursor Position in a Win32 Console Application

Question

How can I set the cursor position in a Win32 Console application? Preferably, I would like to avoid making a handle and using the Windows Console Functions. (I spent all m

Answer 1

#include <windows.h>
#include <iostream.h>
using namespace std;
int main(int argc, char *argv[])
{
  int x,y;
  cin>>x>>y;
  SetCursorPos(x,y); //set your co-ordinate
  Sleep(500);
  mouse_event(MOUSEEVENTF_LEFTDOWN,x,y,0,0); // moving cursor leftdown
  mouse_event(MOUSEEVENTF_LEFTUP,x,y,0,0); // moving cursor leftup //for accessing your required co-ordinate
  system("pause");
  return EXIT_SUCCESS;
}

Answer 2

You were probably using ANSI excape code sequences, which do not work with Windows 32-bit console applications.

Answer 3

See SetConsoleCursorPosition API

Edit:

Use WriteConsoleOutputCharacter() which takes the handle to your active buffer in console and also lets you set its position.

int x = 5; int y = 6;
COORD pos = {x, y};
HANDLE hConsole_c = CreateConsoleScreenBuffer( GENERIC_READ | GENERIC_WRITE, 0, NULL, CONSOLE_TEXTMODE_BUFFER, NULL);
SetConsoleActiveScreenBuffer(hConsole_c);
char *str = "Some Text\r\n";
DWORD len = strlen(str);
DWORD dwBytesWritten = 0;
WriteConsoleOutputCharacter(hConsole_c, str, len, pos, &dwBytesWritten);
CloseHandle(hConsole_c);

Answer 4

Using the console functions, you'd use SetConsoleCursorPosition. Without them (or at least not using them directly), you could use something like gotoxy in the ncurses library.

Edit: a wrapper for it is pretty trivial:

// Untested, but simple enough it should at least be close to reality...
void gotoxy(int x, int y) { 
    COORD pos = {x, y};
    HANDLE output = GetStdHandle(STD_OUTPUT_HANDLE);
    SetConsoleCursorPosition(output, pos);
}

Answer 5

Yeah, you forgot to call SetConsoleActiveScreenBuffer. What exactly was the point of creating your own? Use GetStdHandle(STD_OUTPUT_HANDLE) to get a handle to the existing console.
