    Unwanted space inbetween characters

    Hi;

    i am having problem with this simple line of code.
    im getting char value at WM_CHAR and inputing it in array

    ptext[300] and use textout to output on the screen but i get this

    random unwanted spaces in between characters at times on the output screen what am i doing wrong


    Code:
    ptext[300]
    
    static int  cxchar, cychar, i = 0, x = 0, cxclient, cyclient, j = 0;
    
    WM_CREATE:
    ////////////////////
    
    GetTextMetric(,,,,,,,,,,,,,,,,,,,,,,)
    cxchar = ,,,,,,,,,,
    cychar = ,,,,,,,,,,
    
    ///////////////////
    
    WM_CHAR:
    
    ptext[x] = (char)wParam;
    x++;
    TextOut(hdc, i * cxchar, j, ptext + x, 1);
    i++;
    if((char)wParam == '\r'){
    j++;
    i = 0;
    }
    the characters as i type them appear as follow;


    ffffj kn o sssssl e

    i can do it another way by simply using

    TextOut(hdc, 0, j, ptext, x);
    and getting read of i .

    and it works but i need i somewhere down the code and i want to use the first case .

    thx

    Ok here is the code

    except that now i changed the ptext to a pointer ptextbuff
    but its still the same story
    u need to check the WM_CHAR section only.thx

    by the way the in the code in WM_COMMAND
    by using menue id 51 i wanted to show editbox but it doesnt initializes the window.


    Code:
    #include <windows.h>
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #include <commdlg.h>
    #define ID_EDIT 100
