Hi,
I don't think there is such restriction. How do you set text ?

Hi,
In OnInitDialog i call EnableToolTips(); m_moduleContext.SetModuleToolTipContext(); ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTW, 0, 0xFFFF, OnToolTipText) ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, OnToolTipText) And use BOOL CExResizeDialog::OnToolTipText(UINT, NMHDR* pNMHDR, LRESULT* pResult) from TooltipContextDialog sample. And here the function copy the string from AfxLoadString into the pTTTA->szText buffer. And this buffer has only 80 bytes. Jimmy |

Hi,
1. Catch A and W-Versions: ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, OnToolTipText) ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTW, 0, 0xFFFF, OnToolTipText) 2. Create two member variables: CStringA m_TooltipStringA; CStringW m_TooltipStringW; 3. Beside the ususal black magic in OnToolTipText do the following: [...] TOOLTIPTEXTA* pTTTA = reinterpret_cast<TOOLTIPTEXTA*>(pNMHDR); TOOLTIPTEXTW* pTTTW = reinterpret_cast<TOOLTIPTEXTW*>(pNMHDR); [...] if (pNMHDR->code == TTN_NEEDTEXTA) { m_TooltipStringA = [assign long tool tip text here] pTTTA->lpszText = m_TooltipStringA.GetBuffer(0); } else if (pNMHDR->code == TTN_NEEDTEXTW) { m_TooltipStringW = [assign long tool tip text here] pTTTW->lpszText = m_TooltipStringW.GetBuffer(0); } At least this works for me.

I see that this was changed from 11.1.3 to 11.2.2.
In 11.1.3 only used szText[80]. And in 11.2.2 lpszText will be used. Jimmy |
