listbox creation problems

I'm trying to make a win32 application consisting of one treeview and one listbox side by side. The problem i'm having is that despite seemingly passing the same size to each control on creation there's a weird offset between the two that I can't explain.....

Relevant code is.......

Code:

---

LRESULT CALLBACK WndProc(HWND hwnd,UINT uMsg,WPARAM wParam,LPARAM lParam)
{
        PAINTSTRUCT ps;
        HDC hDC;
        RECT rc;
        TEXTMETRIC tm;
        static HWND hLB;
       
    switch (uMsg)
    {
        case WM_CREATE:
                        g_hTV = CreateTreeView(hwnd);
                        InitTreeViewItems(g_hTV);
                        GetClientRect(hwnd, &rc);
                        hLB = CreateWindowEx(0, WC_LISTBOX, NULL, WS_CHILDWINDOW | WS_VISIBLE | LBS_STANDARD, (rc.right / 2)+1, 0, rc.right/2, rc.bottom, hwnd,NULL, (HINSTANCE)GetWindowLong(hwnd, GWL_HINSTANCE), NULL);

---

Then bit of CreateTreeView()....

Code:

---

        RECT rcClient;        //dim of client area
        HWND hwndTV;    // handle to our treeview
       
        InitCommonControls();
        GetClientRect(hwndParent, &rcClient);
        hwndTV = CreateWindowEx(0, WC_TREEVIEW, "Tree View", WS_VISIBLE | WS_CHILD | WS_BORDER | TVS_HASLINES | TVS_HASBUTTONS | TVS_LINESATROOT, 0, 0, rcClient.right/2, rcClient.bottom, hwndParent, NULL, (HINSTANCE)GetWindowLong(hwndParent, GWL_HINSTANCE), NULL);

---

And a pic demostrating what i might have explained poorly...the red bit shows the messed up bit...

Anybody had any experience like or any thoughts on what might be causing it? Cheers peeps.

Ignore me, I'm an idiot, 5 mins more reading and I could've avoided posting here. For anyone who's remotely interested, it's because according to MSDN "Normally, the system sizes a list box so that the list box does not display partial items." so adding LBS_NOINTEGRALHEIGHT as the list-box style sorted this.....
