string resources in tooltips

Here is the problem, I've created a tooltip and i've set up some dialog item tools (TTM_ADDTOOL) associated with it. It all works fine but I want them to pick up text from resorce strings. Whenever the tooltip loads a string from executable resources It only loads 30-40 chars and then nothing more. Opening the resource script with notepad I can see the string fully registered in the string table. What goes wrong here? I don't think string resources have a limited length so maybe It is a load problem.
Any help is wellcome.

ok, probably when I put the string ID in lpszText member of NMTTDISPINFO structure It tries to load the string resource in szText member which is an [80] char array, so the string is cut. Manually loading should solve the problem.

Code:

case WM_NOTIFY:

if(((LPNMHDR)lParam)->code==TTN_NEEDTEXT)
{
                                       
        LPTOOLTIPTEXT        lpttt=(LPTOOLTIPTEXT) lParam;
        int                idCtrl=GetDlgCtrlID((HWND)((LPNMHDR)lParam)->idFrom);
                       
        static char        cstrToolText[512];

        switch(idCtrl)
        {
        case IDC_XXX:
              LoadString(g_hInstance,IDS_STRING_XXX,cstrToolText,512);
                pttt->lpszText = cstrToolText;
                break;
        }
}

break;
