    Unable to Integrate

    Reply Quote

    I am trying to use CuteChat in a custom web app. I got the stand alone sample up and running, but the integration into my app has been unsuccessful.

    The following code bombs:

                CuteSoft.Chat.Chat_Lobby[] lobbies = ChatWebUtility.Api.GetLobbies();

     The exception details are:

                 System.Xml.XmlException: hexadecimal value 0x12 is an invalid character. Line 1, position 2. 

    When I debug, ChatWebUtility.Api is null.

     I think I’ve created all of the required integration classes in my solution:

    • ConnectionStringProvider
    • DataProvider
    • UserAdapter

    I’ve also got the following records in my Chat_Config table:

    • DataProviderType
    • UserAdapterType
    • Announcement
    • ChannelSkins
    • Description
     In my web.config, I have the following CuteChat key:
    • CuteChat.SqlClient.ConnectionString

    I bought CuteChat but can't currently use it.

    OK .

    Please check the directory CuteSoft_Server/CuteChat/CDQ/

    make sure there only has *.config files , and please check whether the files are xml well formatted .

    Terry,
     
    Ok, now we're getting somewhere.

    We use Visual Source Safe in our dev environment. Source Safe puts a file named vssver.scc in each and every directory in a solution. When I remove this file from my /CuteSoft_Server/CuteChat/CDQ directory, the error goes away.
     
    I suggest that you modify your code so that you don't attempt to parse .SCC files as XML documents.
     
    Thank you,
    -Conrad

    The issue can be somewhat annoyingly addressed by moving the .scc files to a temporary folder while testing your app. Obviously this only an issue in a development environment as source safe files do not get published into production. It would still be nice not to have to "work around" this problem.
     
    Let me rephrase Conrad's statement, '...I suggest that you modify your code so that you don't attempt to parse .SCC files as XML documents... ' if I may...
     
    Will there be any plans to modify your code so that you don't attempt to parse .SCC files?
