ASP Script Takes Longer On Client Than Server
Let me paint the picture: A large MS SQL database (in 7.0) on a Win2K box (not that the Server O/S matters here really) and an ASP page that grabs data from it to present, of course, to the client browser. For the sake of conversation (since I have tested this oversimplified version of the problem) the code pulls a select * from blah (where blah is my BIG table - right now about 25,000 rows).
The problem/question is the time it takes to present the HTML to the client. The big question is...
Why would it take significantly longer to present the final (parsed) HTML on a remote client computer than right on the server? Note: I would normally consider the time it takes to "download" the HTML to the client, but in this case the actual "presented (parsed) HTML" is so small (it's only one integer inside the body tags), that could never account for the difference in time...and I mean significant..on the server...seconds...on a random client computer...many minutes...on my customer's machine...over an hour (which is, of course, my particular problem).
I obviously have to look at their ISP, but a)Again, the end-product HTML is very VERY small and b)the page does eventually present itself (so it's not timing out). I have the scripttimeout set ridicously high so that potential problem doesn't come up, but that's not the problem.
I just want to know what could be causing the significant time difference? Everything I know about the ASP "process" tells me this scenario should never happen (unless the HTML being sent is significant, of course, like a huge list, or something).

I have a Fedora Core 4 server with cPanel which is my master server shall I say. And 2 days ago, cPanel did an update which brutally murdered my MySQL 4.0.25 on the system, so I was forced to upgrade to 4.1.18. So we did that, and all is working now...
Now, my business has satelite servers that revolve around the master server. It allows people to remotely start and stop services on those satelites, and it uses ASP to remotely connect from the satelite, to the MySQL database on the master server to retrieve information regarding the users.
So yesterday, after the upgrade, my satelites seemingly connect to the MySQL server (it does not give an error), but it does not perform a correct query, thus no users on the network can start or stop their services. It just says "Invalid user or server". Now, the MySQL connection is working, because I have other software that authenticates thru the Master Server MySQL database that is working perfectly... I just think it is something wrong with the code on this Activ Serv... I had the program custom written about 2 years ago..
I have tried upgrading the MyODBC driver from 3.51.10 to 3.51.12 and that did nothing to help.
I have the entire code which is right here. Of course it uses a executable on the server to start/stop services and collect process ID information. But the queries are not working correctly so the executable never even runs... Code:

I need to know if, and how, it is possible to use ASP to download a file automatically from the web server to the client in a given path. Is that possible ? Ideally I want a page with a link that when pressed it will copy a certain file that exists on the web server down to the client.

My boss told me web application is NOT client-server application. I argued
with him because browser is the client, and the server code put in server.
Then web application should be a client-server application. My understanding
is that a web application is an application that runs on a browser. But
client-server application is not necessary a web application.

There is a client and a server. They both share a folder structure that is identical. The client is able to copy and import files to and from the server with button click.
The client is running IIS and some local scripts. The client also has a network drive mapped to the SERVER location.
Is there a way I can copy files without running IIS on the clients machine? The server needs to pass the file info to the Client. Also keeping in mind that I can't get IE to open file protocol links.

I am having a problem executing long running queries from an ASP application which connects to SQL Server 2000. Basically, I have batches of queries that are run using ADO in a loop written in VBScript. This works pretty well until the execution time of a single query starts to exceed some threshold, which I am trying to narrow down. I can typically run 2 - 10 queries in a loop, with the run time being anywhere from under a minute to an hour or more. Now that this application is being subjected to run against some large databases (25 - 40G), I'm having problems getting the application to continue beyond the first query if it takes a while to run.
I used SQL Profiler to try to diagnose what was going on. I can see the query executes to completion, but immediately after completing I can see an "Audit Logout" message, which apparently means that the client has disconnected. The query durations vary from 45 or 50 minutes to up to over 90 minutes. I have the ADO connection and query timeouts set to very large values, e.g. 1000 minutes, so I can't think its that. My guess is that there is some IIS setting or timeout that I am running up against and the connection to SQL Server is just dropped for some reason.
The configuration is
NT 4.0 SP6
SQL Server 2000 SP3
IIS 4.0
Explorer 5.5
I'm only running into this problem on the very largest databases we run against. The vast majority continue to function properly, but this is going to happen more often as time goes on the databases continue to grow in size.

At the moment I am building a small news board on my companys intranet. There are 2 different offices with 2 different domains. for each office I want to show different news relating to that office.
Is there any way with asp to get the name of the domain that the user is logged onto so I can filter different news for each domain. This will just save the hassle of putting the intranet on 2 different domains.

I want to know the possiblity and process of an ASP client, which needs to get some UDT from a ATL Server component implemented in VC++. The UDT is basically a C++ class consisting of a BSTR and a short. for eg.,
class CMyClass
{
BSTR myName;
short myNum;
};
and what actually i need is to pass a collection(vector) of this object to ASP client as well as to a VC++ client.

The jist of what i want is the obj.FileExists (how it checks for a file on the server) for the client machine.
The client will be scanning something that will put a pdf file into a shared folder on their machine (it will be the same path for all clients). I need to get the code* to pull that file so that i can take the data on the pdf.
*Code doesn't have to be ASP. i'm up for ASP, VBScript, Javascript.

Normally when I do serverside processing and if the string may contain < or > characters in the userdata I would do:
<%=Server.HTMLEncode(userdata)%>
However if I'm doing client side processing is there any equivalent VB function that I can call to do just that, or do I have to write my own routine to convert < to < and > to >, etc?

Suppose I load data from a database and store it in a VBScript array using asp (i.e. this is all done from the server)
I then want to have some client side scripts (they have to be client side because they are activated depending on what the user does on the page). Is there any way of accessing the array generated at the server, through the client side scripts???
If not, how else can I write my page?? The data is loaded from a database, which is obviously done at the server. If not by doing what I have already described, how else can i use the database data in my client side scripts???

I have a chunk of code, where based on the user's selections, it goes through a database and selects all of the records from the database and writes them to a text file (the database contains nearly 600,000 records), currently, the file is written and the user would end up having to wait for it to be written, before continuing.
Is there a way that this file could be kind of.... tagged or something, so that the server creates it in the background, instead of while the user waits, so the user can continue doing other things, rather then having to wait for the text file to be created.
The files can be quite large, as they can end up being anywhere from 1 - about 600,000 records with between 4 - 10 fields each. Here is a sample of the code that creates the text file. Code:

How do I go about calling a server-side vbscript within a client-side
javascript function? What I have is a page heavy on the javascript that has
a number of functions, one of which is to begin a visual countdown with an
onclick and also open an asp page containing the server-side vbscript, which
initiates a wake-on-lan call. I had no idea how to call the vbscript within
the javascript function, so this is why I opted for the vbscript asp page
"pop-up" via window.open. Code:

I am starting to build quite a few pages that will have
tables of data from an SQL database.
I have been building the table rows on the server side
in VBScript, but I have been thinking about having the
VBScript code just build array variables in the <head>
section (or as local variables), and then have JavaScript
functions on the client side actually populate the tables
when the page loads.
I do plan to do other things like being able to sort the
tables in JavaScript code on the client, limit the tables
height and be able to scroll the rows, and click on a row
in the table, and have the values populate a form. I will
also need to be able to export/download/? some tables into
Excel.
