I am developing a chat in an application using the SGCWebSocket library, I was able to do the exchange of messages and the list of my users when connecting and disconnecting in the system, however I am encountering some problems when accessing objects in the client application when I try to access the objects in an event of the SGC protocols, generating an access violation. below has the source code that I use in the onEvent of the message protocol, the commented line is where error occur, when trying to display a notification on the screen(groChat.Show;): procedure TfrChat.WSProtClientEvent(Connection: TsgcWSConnection; const Channel, Text: string); var groChat : TIDSiGrowl; begin groChat := TIDSiGrowl.Create(nil); groChat.Text := Text; groChat.Title := Channel; // groChat.Show; end;
