ChatProvider not initialized
We are trying to install the live support stand alone version. We have the demo working on our local machine in C but are having trouble getting it to work in VB.
We are getting the error
CuteChat.AppChatIdentity identity = CuteChat.ChatProvider.Instance.GetLogonIdentity();
We have installed the global file at the root and are wondering what we are missing?

Hi northerncs,
do you missing steps below?
-----------------------------------------------------------------------
Initialize an instance of provider when the application starts:
CuteChat.ChatProvider.Instance = new MyChatProvider();
CuteChat.ChatSystem.Start(new CuteChat.AppSystem());
-----------------------------------------------------------------------

Re: ChatProvider not initialized
I have the following code in the Global.asax at the website root.
CuteChat. ChatProvider.Instance=new ExampleProvider();
CuteChat. ChatSystem.Start(new CuteChat.AppSystem());
And I get this error

Re: ChatProvider not initialized
I am trying to implement the example solution into a VB project. Is this the cause of the errors?

Re: ChatProvider not initialized
I am trying to get live support to work.
Before posting to this forum I did get the demo to work in c# but I am integrating this into a VB application. For some reason I can't get the livesupport to integrate with VB. I copied all the files from the C# application into the VB one and it gives me the error mentioned at the top of this thread.
That is why I am wondering if having the global file written in C# will interfer. Trying to figure out what I am missing as the code is identical.

Re: ChatProvider not initialized
Can you post your full "Global.asax" and chat provider here?

I call it using this. Not sure what you all need for this portion. I used the stand alone demo.

Re: ChatProvider not initialized
Hi northerncs,
Is your site online? If so, can you set up ftp access for me? I will check it and get back to you as soon as possible.

Re: ChatProvider not initialized
One other thing. When i try to connect with the software it says, Login Form return OK, but login failed!
I uploaded the CuteChat tables to SQL server and added the default username and password.

Hi northerncs,
File "CuteSoft_Client/CuteChat/SupportService.asmx" does not work on your site.
So, please make sure your site can run asmx file correct.

ken

Re: ChatProvider not initialized
When I go to the directory in question the samples appear to work. I only have a basic knoledge of SOAP and XML posts.
When you go to the above page do you get an error?

Hi northerncs,
I change your Global.asax, like below.
public override bool ValidateUser(string loginName, string pwd)
{
string nickName=null;
string password=null;
bool isAdmin=false;
bool exists=GetUserInfo(loginName,ref nickName,ref password,ref isAdmin);
if(!exists)return false;
if(password!=pwd)return false;
System.Web.Security.FormsAuthentication.SetAuthCookie(loginName,false,"/");
return true;
}
Change to
public override bool ValidateUser(string loginName, string pwd)
{
if (HttpContext.Current.User.Identity.IsAuthenticated)
{
return true;
}
else { return false; }
}
---------------------------------------------------------------------------------------
Now, please create a test account to test it. and make sure the account is administrator.
Regards,
ken

Re: ChatProvider not initialized
I have the default install with the default credentials.
Table SampleUsers
Fields
LoginName NickName, Password, Email, IsAdmin
|
admin |
admin |
admin |
admin@localhost.com |
1 |
It says "You entered an invalid password".
Is it expecting the password to be encrypted in the database?

Hi northerncs,
Just confirm something.
Do you have your own membership database? Or just use our demo database (install by CuteLiveSupport.sql)?
If you using our demo database, just need to use the "Global.asax" in our demo. Do not need create your own chat provider.
I suggest you deploy our demo as a separate application to test.
If it works, then integrate your own membership.
Regards,
Ken
