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.

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.
