TODO: dialog box or debug.log warning if no rpc.user/rpc.password is set, explaining how to set.
In many of the contexts of this RPC stuff, you can print to the console with fprintf(stdout, like this: #if defined(WXMSW) && wxUSE_GUI MyMessageBox(“Warning: rpc password is blank, use -rpcpw=<password> ”, “Bitcoin”, wxOK | wxICON_EXCLAMATION); #else fprintf(stdout, “Warning: rpc password is blank, use -rpcpw=<password> ”); #endif
