Wnerwiało mnie wstawianie kwadracików, zamiast kasowanie ostaniego wyrazu (CTRL+Backspace), i nie obsługiwanie CTRL+A w standardowym editboxie windowsowym, więc poprawiłem

WNDPROC editProcOld;



//usage:

//include it & put it after CreateWindow(”edit”,…)

//editProcOld = (WNDPROC)SetWindowLongPtr(my_edit,GWLP_WNDPROC,
(LONG_PTR)editProc);





LRESULT CALLBACK editProc(HWND hWnd,UINT iMsg,WPARAM wParam, LPARAM
lParam){


 switch(iMsg) { //podobnie jak w tb_proc_new


 case WM_CHAR:{
 short tmp =
GetKeyState(VK_CONTROL); 
 short flag =
(HIBYTE(tmp))?MOD_CONTROL:0;
 if(flag==MOD_CONTROL
&& HIBYTE(GetKeyState(VK_BACK))){
 int dlugosc =
SendMessage (hWnd, WM_GETTEXTLENGTH, 0, 0 ) + 1;

body_tmp = new char[dlugosc];

GetWindowText(hWnd,body_tmp,dlugosc);
