    Exclamation Confuse With The Simple Things~~the console programming.look for help!

    The code like this:
    Code:
    #include <stdio.h>#include <windows.h>
    
    
    int main(int argc, char *argv[])
    {
    	DWORD cNumRead, fdwMode, i, numInput; 
        INPUT_RECORD irInBuf[128]; 
        INPUT_RECORD InputInfo;
        HANDLE hIn;
        hIn = GetStdHandle( STD_INPUT_HANDLE);
    	while( 1)
    	{
    		GetNumberOfConsoleInputEvents( hIn, &numInput);
     		if( !numInput)
     			continue;
    		ReadConsoleInput( hIn, &InputInfo, 1, &cNumRead);
        	printf("%d, %d\n", 
    			InputInfo.Event.MouseEvent.dwMousePosition.X,
    			InputInfo.Event.MouseEvent.dwMousePosition.Y);
    	}
    }
    but the result dose not like what i want.

    value
    InputInfo.Event.MouseEvent.dwMousePosition.Y
    was wrong~ i don't no why~
    help~~~

    Perhaps check that InputInfo.EventType == MOUSE_EVENT before trying to print anything mouse related.
    INPUT_RECORD structure
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I thinke about it, I just wanna try the Mouse Event.
    I add the
    if( InputInfo.EventType != MOUSE_EVENT) continue;
    but the result has nothing change.the value Y was also wrong.
    it increase to about 300.

    i modify the code Reading Input Buffer Events
    but the result was also the same ~
    next is the changed
    Code:
        while (1)     { 
            // Wait for the events. 
     
            if (! ReadConsoleInput( 
                    hStdin,      // input buffer handle 
                    irInBuf,     // buffer to read into 
                    128,         // size of read buffer 
                    &cNumRead) ) // number of records read 
                ErrorExit("ReadConsoleInput"); 
     
            // Dispatch the events to the appropriate handler. 
     
            for (i = 0; i < cNumRead; i++) 
            {
                if( irInBuf[i].EventType != MOUSE_EVENT) continue;
    			printf("%d, %d\n", 
    				irInBuf[i].Event.MouseEvent.dwMousePosition.X,
    				irInBuf[i].Event.MouseEvent.dwMousePosition.Y);
            }
        }

    Because as you print new lines, the console scrolls down its buffer till it gets to the bottom (which defaults to 300).

    The docs point it out:
    dwMousePosition
    A COORD structure that contains the location of the cursor, in terms of the console screen buffer's character-cell coordinates.
