C++ Listview tooltip

I've got a listview in report view that I'm trying to display tooltips for, different per item.

But I can't get any tooltip to be displayed at all...

Here's what I figured out so far:

case LVN_GETINFOTIP:
{
    LPNMLVGETINFOTIP GetInfoTip = (LPNMLVGETINFOTIP) lParam;
    GetInfoTip->pszText = L"TESTING";
    // What do I do now? How do I display the tooltip?
    return 0;
}

After I have received the LVN_GETINFOTIP message, how do I display the tooltip?

Solution

  • The problem is that you are replacing the pointer pszText. You need to modify the contents of the memory buffer instead. For example using StringCchPrintf.
