В окошке хочу выделить текст в лево (до начала строки) от положения каретки. Накрапал ф-ции в Бейсике работает, а в VC++ нет. Подскажите, что тут не так.
Спасибо!

void SelectStr(HWND hwnd, POINT pt)
{
POINT pt1, ptCaret;
RECT rc;
ULONG curx, screenx, screeny, ptsperx, ptspery;
BOOL mous;
int numStr1C, offset, b;

offset = 13;

mous = FALSE;

b = GetWindowRect( hwnd, &rc );

ptCaret.x = pt.x + 2;
numStr1C = ((pt.y - rc.top) / 13 + 1);
ptCaret.y = pt.y + 13;

pt1.x = 2;
pt1.y = rc.top;

b = ClientToScreen( hwnd, &pt1 );
screenx = GetSystemMetrics(SM_CXSCREEN);
screeny = GetSystemMetrics(SM_CYSCREEN);

ptsperx = ptCaret.x * (65535 / screenx);
ptspery = ptCaret.y * (65535 / screeny);

mouse_event( MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE, ptsperx, ptspery - offset, 0, 0);
if (!mous)
mouse_event( MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_RIGHTDOWN, ptsperx, ptspery - fset, , 0);
else
mouse_event( MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTDOWN, ptsperx, ptspery - offset, 0, 0);

curx = pt1.x * (65535 / screenx);

mouse_event( MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE, curx, ptspery - offset, 0, 0);

if (mous == FALSE)
mouse_event( MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_RIGHTUP, curx, ptspery - offset, 0, 0);
else
mouse_event( MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTUP, curx, ptspery - offset, 0, 0);


SetTextToClip();
mouse_event( MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE, ptsperx, ptspery - offset, 0, 0);
}

void SetTextToClip()
{
UCHAR altscan, cscanVK_C, cscanVK_Z, cscanVK_A;
UCHAR VK_A = 65, VK_C = 67, VK_Z = 90;

altscan = MapVirtualKey(VK_CONTROL, 0);
cscanVK_C = MapVirtualKey(VK_C, 0);
keybd_event( VK_CONTROL, altscan, 0, 0);


keybd_event( VK_C, cscanVK_C, 0, 0); //copy
keybd_event( VK_C, cscanVK_C, KEYEVENTF_KEYUP, 0);
cscanVK_Z = MapVirtualKey(VK_Z, 0);
keybd_event( VK_CONTROL, altscan, 0, 0);
keybd_event( VK_Z, cscanVK_Z, 0, 0); //undo
keybd_event( VK_Z, cscanVK_Z, KEYEVENTF_KEYUP, 0);

cscanVK_A = MapVirtualKey(VK_A, 0);
keybd_event( VK_CONTROL, altscan, 0, 0);

keybd_event( VK_A, cscanVK_A, 0, 0); //redo
keybd_event( VK_A, cscanVK_A, KEYEVENTF_KEYUP, 0);

keybd_event( VK_CONTROL, altscan, KEYEVENTF_KEYUP, 0);
}

А для чего ты так делаешь?
Может быть лучше воспользоваться функцией SetSel()?
