You could enumerate the windows looking for a tooltip control that has a parent of the required window. You'll need to supply the window together with the tool id (normally from GetDlgCtrlID
)...:
HWND hToolTipWnd = NULL;
BOOL GetToolTipText(HWND hWnd, UINT nId, std::wstring& strTooltip)
{
hToolTipWnd = NULL;
EnumWindows(FindToolTip, (LPARAM)hWnd);
if (hToolTipWnd == NULL)
return FALSE;
WCHAR szToolText[256];
TOOLINFO ti;
ti.cbSize = sizeof(ti);
ti.hwnd = hWnd;
ti.uId = nId;
ti.lpszText = szToolText;
SendMessage(hToolTipWnd, TTM_GETTEXT, 256, (LPARAM)&ti);
strTooltip = szToolText;
return TRUE;
}
BOOL CALLBACK FindToolTip(HWND hWnd, LPARAM lParam)
{
WCHAR szClassName[256];
if (GetClassName(hWnd, szClassName, 256) == 0)
return TRUE;
if (wcscmp(szClassName, L"tooltips_class32") != 0)
return TRUE;
if (GetParent(hWnd) != (HWND)lParam)
return TRUE;
hToolTipWnd = hWnd;
return FALSE;
}
