    Database Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied

    Hi guys,

    I just downloaded the CuteChat v1 and runs on a Win2003 Web Edition server and MSDE, no other dotnet forum softwareinstalled, so I used the CuteChatSample. I manually installed the CuteChat and when I enter the admin and password credential on the default page, it turns out these errors:
     
    Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    Exception Details: System.Data.SqlClient.SqlException: SQL Server does not exist or access denied.

    Source Error:

    An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

    My configurations on Web.Config are:
    server=MSDESQL;database=CuteChatSample;UID=websqlquiry;PWD=abcde;App=CuteChat (websqlquiry is made the dbo of the cutechatsample database)
    3. Configuration/cuteChat/Providers/Provider@
    name ="Sample" sqlDataProviderType="CuteChatSample.SQLOLEDB,CuteChatSample"
     
    Can you advise me any part of the configuration is wrong, or it is something else?
    Thanks in advance.

    Re: Database Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied

    Hi Rgain :

     
    Your connection string is :
    server=MSDESQL;database=CuteChatSample;UID=websqlquiry;PWD=abcde;App=CuteChat
     
    Is the MSDESQL the name of your pc ? or it's just an instance of SqlServer on your pc?
    If so , the connection string should be :
     
    server=localhost\MSDESQL;database=CuteChatSample;UID=websqlquiry;PWD=abcde;App=CuteChat
     
    and the provider 'Sample' should be :
    <provider name="Sample" sqlDataProviderType="CuteChatSample.MySqlDataProvider,CuteChatSample" />
     
    (The CuteChatSample.MySqlDataProvider is an buildin class for the sample , please see CuteChatSample/MySqlDataProvider.cs for more)
     
    --------
     
    You could run [START]-[Program]-[CuteChat]-[CuteChat Configuration] to help you create a new sample application too.
     
    Hope this helps.

    Re: Database Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied

    Thanks alot CuteChat. Yup, I made a mistake on the providertype and gave the wrong name of the server, it should have been (local).

     
    By the way, why can't I type any thing in the editor after I logged in? I tried on both your Source Projects Demo and my new installation. The page loaded perfect, but when I type something into the editor box and click send, there isn't any response. Same case when I click on the "Bold", "Smiley", etc buttons. In fact, those are not buttons on the page.
     
    Appreciate your advices anyway. Pretty neat and cool app.

    Glad that I could help :-)
     
    Do you see these words on the screen ?
     
    Please wait, connecting to server... ... ...

    Connected!

    'MyName' joined the room.
     
    And see 'MyName' in the Online List panel ?

    Re: Database Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied

    Hi Lijian,

    No, there isn't any thing like that. I can see the chatroom screen, but not "MyName" and "connecting to server". The page is simple static.

    Re: Database Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied

    By the way, if I get a proper installation of the CuteChat, is there any changes I'm supposed to see under IIS WebServiceExtensions, like there will be an cutechat.dll and cutechatsample.dll displayed?

    Re: Database Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied

    Rgain:

     
    Maybe , the 'Norton AntiVirus' block the script ?
    Could you test the chat room in another pc that the AntiVirus softwares are not installed ?
     
    If you depoy the CuteChat using the 'CuteChat Configuration' program , after all step runs , these things would be done:
     
    1.the DataBase would be setuped.
    2.the web.config would be merge to target application.
    3.the CuteChat/*.* would be copied to target application
    4.the CuteChat.dll,CuteChat....dll would be copied to target\bin

    Re: Database Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied

    Hi Adam & Lijian,

    Thank you so much for the point out. It was the Norton AV script block that caused the problem. I tested on three computers and the results are follow:
    1. Norton AV installed, script block on = can't work
    2. Norton AV installed, script block off = can't work
    3. Norton AV not installed = works normally. However, sometime the chat windows will hang if three connecting retries were attempted
     
    I just installed the ASP.Net Forum v.2 and worked properly. Then I tried to use the CuteChat config wizard to integrate it with the ASPNF2. It all worked fine until I click "Next" on the "Setup the web.config" page. The errors as follow:

    ************** JIT Debugging **************
    To enable just in time (JIT) debugging, the config file for this
    application or machine (machine.config) must have the
    jitDebugging value set in the system.windows.forms section.
    The application must also be compiled with debugging
    enabled.

    For example:

    <configuration>
        <system.windows.forms jitDebugging="true" />
    </configuration>

    When JIT debugging is enabled, any unhandled exception
    will be sent to the JIT debugger registered on the machine
    rather than being handled by this dialog.

     
    I couldn't proceed from here onwards. So I skipped the Web.Config setup and proceed on.
    The next thing I did was to open the "web.config" file in the ASPNF2 root directory and changed the following in red:
     
    1. Configuration\CuteChat\Providers@defaultProvider="AspNetForums"
    2. Configuration\CuteChat\Providers\Provider : name="AspNetForums" sqlDataProviderType="CuteChat.AspNetForums2Lib.AspNetForumsSqlDataProvider,CuteChat.AspNetForums2Lib" userIdentityAdapterType="CuteChat.AspNetForums2Lib.SqlServerUserIdentityAdapter,CuteChat.AspNetForums2Lib"
     
    At first it displayed just like the one in your demo. but ever since I clicked the CHAT button on the forum, it becomes like:
     
     

    Server Error in '/Forums' Application.

    Re: Database Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied

    Hi again,

    The problem's found:
     
    In the decompressed package of the CuteChat, there's a folder (C:\Program Files\CuteSoft\CuteChat\Toolkit\bin\Debug) which contains another CuteChat.dll and CuteChat.pdb which seem different from the ones in the (C:\Program Files\CuteSoft\CuteChat\CuteChatSample\bin). The wizard copys the CuteChatSample version into the ASPNF2 instead of the ones from Toolkit.
     
    Now the app works fine.
    Thank you anyway.
     
    Best regards,

    Re: Database Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied

    Rgain :

     
        Thanks for verifying the antivirus problem . We would mention developers that issue.
     
    You get the known problem , which is resolved , but not be published .
     
    The reason is that the 'Culture' has not been binded anything. 
     
    It's wired , you could wait for the next release in few days, or try this :
     
    When get in the setup of DataBase configuration , choose 'Skip DataBase Configuration' , and click 'Next'
     
    and then , the 'Culture' would fill with 'en-us' and more .
     
    and then you could fill the ConnectionString manually , and continue
     
    ---------------
     
    The 'Metadata file' not found bug is known bug in Asp.Net 1.0/1.1
    To resolve this problem , the ASP.NET must re-copy the 'shadow assemblies' , there are some ways :
     
    A. iisreset
    B. re-copy the dll into the bin
    C. create a new file in the bin folder , and modify it and save it .
     
    Regards , Lijian .

    Re: Database Error : System.Data.SqlClient.SqlException: SQL Server does not exist or access denied

    I haven't resolved all the problem, coz I still can't open the chatroom with the ASPDNF2 integration.
    Anyway, Thanks alot, Lijian. I will wait for the next release of the CuteChat.
     
    I really appreciate your quick response on product support. I'm looking forward to purchase a copy of CuteChat once I get a successful installation soon. By the way, after I purchased a license, do I have to change anything on the installed trial copy?
     
    Best regards,
     
    Rgain
     
    Keep up the good work.

    Rgain,

     
    All you need to do is overwrite the trial license file with the license file we send to you.
