I decided to give it a go and wow it was way harder than I thought it should be.  Here is what I ultimately did. (you can try playing with ITextDocument2, ITextRange2::SetURL, but I didn't get that to work like I wanted.  I finally resorted to
directly injecting RTF into my RichEdit control.  Here is a brief example (there is a little MFC in here to save time, but the relevant stuff is pure Win32 and the MFC is trivially convertable to Win32).
m_rich.Create(WS_VISIBLE | WS_CHILD | ES_MULTILINE, CRect(10, 10, 200, 200), this, 1000);
// TODO: Add extra initialization here
m_rich.SetWindowText(L"This is a test ");
m_rich.SetSel(-1, -1);
m_rich.SetEventMask(ENM_LINK);
std::string dataStr = R"({\rtf1{\field{\*\fldinst{ HYPERLINK http://example.com }}{\fldrslt{DisplayText}}}}.)";
std::list<char> dataList(dataStr.begin(), dataStr.end());
EDITSTREAM es = {
reinterpret_cast<DWORD_PTR>(&dataList),
0,
[](DWORD_PTR dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb) -> DWORD {
auto &list = *(reinterpret_cast<std::list<char> *>(dwCookie));
*pcb = 0;
while (*pcb < cb && !list.empty()) {
pbBuff[*pcb] = list.front();
list.pop_front();
(*pcb)++;
return 0;
auto r = m_rich.SendMessage(EM_STREAMIN, SF_RTF | SFF_SELECTION, reinterpret_cast<LPARAM>(&es));
