Setting the Cursor Position in a Win32 Console Application
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 morning running down that dark alley; it creates more problems than it solves.) I seem to recall doing this relatively simply when I was in college using stdio, but I can't find any examples of how to do it now. Any thoughts or suggestions would be greatly appreciated. Thanks.
Additional Details
Here is what I am now trying to do:
COORD pos = {x, y};
HANDLE hConsole_c = CreateConsoleScreenBuffer( GENERIC_READ | GENERIC_WRITE, 0, NULL, CONSOLE_TEX开发者_如何学GoTMODE_BUFFER, NULL );
char * str = "Some Text\r\n";
DWDORD len = strlen(str);
SetConsoleCursorPosition(hConsole_c, pos);
WriteConsole(hConsole_c, str, len, &dwBytesWritten, NULL);
CloseHandle(hConsole_c)
The text string str
is never sent to the screen. Is there something else that I should be doing? Thanks.
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);
}
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);
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.
You were probably using ANSI excape code sequences, which do not work with Windows 32-bit console applications.
#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;
}
