Pelles C forum

I have the following code for a tootip from a toolbar. For me all seems to be correct but the tooltip is not displayed. Can anyone help me. Thanks.

I have found!

@GetDispInfos :


                     mov      rdx,[r9].NMTTDISPINFO.hdr.idFrom
                     or      [r9].NMTTDISPINFO.uFlags,TTF_DI_SETITEM or TTF_IDISHWND
                     mov      [r9].NMTTDISPINFO.hinst,0
                     mov      rax,OFFSET hInstance
                     lea      r8,[r9].NMTTDISPINFO.szText
                     mov      rcx,[rax]
                     mov      [r9].NMTTDISPINFO.lpszText,r8
                     mov      r9,80
                     call   LoadStringA

                     xor      rax,rax
                     ret


The problem was caused by this line :

OR [r9].NMTTDISPINFO.uFlags,TTF_DI_SETITEM or TTF_IDISHWND

TTF_IDISHWNDIf this flag is set, idFrom is the tool's handle. Otherwise, it is the tool's identifier.

Toolbar can load string from resource in this way too:void OnNotify(HWND hwnd, int idCtrl, NMHDR* pNMHdr)
{
switch (pNMHdr->code)
{
case TTN_NEEDTEXT:
{
((LPTOOLTIPTEXT)pNMHdr)->hinst = hInst;
((LPTOOLTIPTEXT)pNMHdr)->lpszText = MAKEINTRESOURCE(((LPTOOLTIPTEXT)pNMHdr)->hdr.idFrom);
return;
}
}
}
