Dear to whom it may concern

We have a license for Teechart 5.

Recently, we have upgraded operating system of web server from Windows 2000 Server(IIS 5) to Windows 2003 Server(IIS 6).

When we used Windows 2000 Server, there was no problem with Tchart 5 with our web site.

However, after the upgrade from 2000 Server to 2000 Server, a severe problem is found with Tchart 5.

There is no change in our 2003 Server's source code in comparison woth that of 2000 Server.

When a user call the following code in server's program, the other users are restricted to use the code and site.

The source code inducing the above problem : Response.BinaryWrite (Chart1.Export.asNative.SaveToStream(True))

Question : Let us know the compatible OS version with Tchart 5.
On top of that, if you give the solution to the above mentioned
problem, it will be very helpful for my team.

Hi SEC,

Have you tried running the ASP Server Examples available at TeeChart's program group. There's one concrete example which uses the statement which causes you those problems. The example is Return template Chart Example. The source code for those examples is also available at TeeChart's examples folder. Could you please try running this example on the server to see if it works?

By the way, TeeChart Pro v5 ActiveX works fine with Microsoft Windows 2000 and 2003 versions.

I'm sorry that I still have this catastrophe.
Last week, I applied the example to my server.
However, it was still hanging at the code, "Response.Binarywrite."
The symptom is that nobody can connect this web server after this
problem.
According to a Server2003 technician in my team, it is certain that the code cause this problem.

Please let me know how to solve this problem.

Hi SEC,

Can you run any ASP or ASP.NET application without TeeChart on it on that server?

SEC · Post by **SEC** » Thu Feb 02, 2006 12:38 am

Sure.

Any other ASP page is running well.
But, only a few ASP pages with teeChart are causing the problem.
As below, no one can connect all the pages after a huge data is executed
at the "Response.Binarywrite(Chart1.Export.asNative.SaveToStream(True))."
Also, request-queue in my server increases and does not return the resource.

Could you need the more information?
My team members and I have taken more effort to solve this.
Please help us.
