It was the only way I know to reload the first page (where user credentials are entered) using ASP. If it's a problem today, it should have been a problem yesterday, as well, along with the several weeks I've been using it reliably. I haven't made any aspx pages yet, so mixing pages is not a problem, either.
I've had trouble with session variables before, with some of them in global.asa being correctly intialized, but others being left undefined for no apparent reason. But this one has worked perfectly since the day I wrote it. I've read many warnings to avoid session variables as unreliable entities in books and on the web, so I haven't been concerned about the occasional eerie failure as long as there was another way to get the job done.
I just love mysteries... I can always count on Windows and IIS to keep me entertained.

The normal way is to use Response.Redirect "filename.asp"

AFAIK Server.Transfer does a whole lot more than Response.Redirect, which might be what is causing the problem. You are right though that installing the .NET Framework should not have caused a problem. Server.Transfer though generally is used on server farms where you need Session data to move from one server in the farm to the other. Response.Redirect will not do this. If I start on Server1, some Session info is captured and I am then moved to Server2 without a Server.Transfer then I loose that Session info.
I don't know actually Roger, searching Google now for people who have had a similar problem to you. As you say " I can always count on Windows and IIS to keep me entertained"

You're not going to believe this (well, maybe you will), but after spending the morning trying to figure out what is going on today that wasn't yesterday I walked away from it for a couple of hours, then returned to it. Now it's working perfectly, though I've changed nothing. I think I'll look at that Redirect option as you suggested. Thanks!

I will have to disgree with you. Response.Redirect works in conjunction with the browser. IIS sends a response with HTTP status code 302 and the new url to the browser when you call Response.Redirect. The browser than renavigates to the page. Server.Transfer is more efficient in the sense that it doesnot cause any extra network trips look at this page which explains it more clearly.

One of the things I learned involved copying & pasting the code. You'll notice that some of the code is virtually the same for each player, I had forgotten to change the files for player 2 for upgrade. I finally noticed it and provided the fix.

Yes but for one you cannot use a querystring with Server.Transfer, a big minus mark IMO.
Server.Transfer is a more recent addition. Hence why I said Response.Redirect is the normal way.
They are used for different things.

Having spent the rest of the day and most of the night trying to get Response.Redirect to work, I now have a completely non-functional site. It redirects nicely, but the page I want to display to inform the user that access is not allowed never displays. I've tried it with buffering on and off, and using Clear and Flush in various combinations - no go. The text I use for a reference recommends that the newer functions, Server.Transfer and Server.Execute, be used instead of Response.Redirect in almost all situations. One idiosyncracy I haven't been able to figure out yet is that, when it is working properly and displaying the message before transferring back to the first page, the text is merely added to the current page being displayed. There must be some way to clear the existing page out of the browser and display the message as a new page! The fun factor is rapidly diminishing here...

in this setuation Transfer won't work..
you need to redirect.
one problem with redirect is that it causes some problems if the uses is viewing the page behind a proxy..
try to use some Client script to handle your problem..

I hadn't thought of that... one of my goals in this project is to write the whole thing to execute on the server, but I've already had to break that in order to set the default focus on a specific INPUT field. Redirect makes it impossible to display any text at all, so it's useless. But adding some client side stuff might be the ticket... Thanks for the suggestion!

I know. Had to go back to a VBScript/ASP project the other day and I felt so uncomfortable coding. Kept putting in ; and wanting to use } instead of end if etc.

What exactly isn't working? I assume you get a VBS error message of some kind.

Yeah, right! No, there are no error messages - which only says that the code is perfectly valid VBS, but my understanding of what I've written is defective.
Actually, Jason, I've got everything working almost satisfactorily. It's a simple login routine - nothing fancy - that asks for id, checks its validity, and displays a 'Go Away' message if the login fails. It works, though not the way I'd like, because my intent is to display the message, wait a few seconds, then display the login screen again. What I get, though, is the message at the top of the screen, and the login appended after it, and both appear after the delay period, rather than in the order they're written (msg - delay - transfer). Very odd.

Could be the buffering. If it is buffered it will wait until the page is compelete before sending it. If you want a delay you could use a meta tag in the "go away" page that causes it to refresh after x amount of seconds. Would have the added bonus to allow the user to hit refresh for instant login screen.

Yes, I think that's somehow related, but I can't see how to correct it. I tried turning buffering on and off, but it didn't seem to change the behavior much. I'm still playing with it, though...

How do you turn off buffer, is in IIS or in the script on the page with Response.Buffer = FALSE?
Here is a little test script:
<% Response.Buffer = TRUE %>
<html>
<!-- -------------------------------------
-------------------------------------
-------------------------------------
-------------------------------------
-------------------------------------
-------------------------------------
-------------------------------------
-->
<body>
<p>Hello There</p>
<% response.flush
for i = 1 to 5000000
next
%>
<p>Something to happen</p>
<% response.flush
for i = 1 to 5000000
next
%>
<p>Ok</p>
</body>
</html>
This works on my system with a buffered page. If you turn off buffering and drop the flush lines, it should work the same. Had to add the comment section to give the page enough bulk to be accepted. If I remove them, it will process the entire page even with the flush lines before it is actual written out.
The true question here though is if you are using redirect or transfer. If you are using redirect, you can scrap this entire idea. The redirect it a special header sent that has to be sent first. Thus nothing will be displayed and it will redirect to a new page. Does not matter if you flush or not, the header has to be first.
Server.Transfer does not work since it has already output the header information for the request and the Server.Transfer just continues the stream that was already started.
The best solution in situations such as this is to use a meta tag refresh for the time you want to cycle. You can then redirect the page to itself or any other page. You would use something like:
That would refresh that page in the client's browser in 4 seconds and send it to the url listed. The added benifit is that if the user hits their refresh button before the 4 seconds is up, it will cut short their wait.

Thanks for the examples! I was using Response.Buffer to control buffering, and tried mixing in some Flush commands in various places to see how the behavior varied. It didn't. The meta tag technique is more along the line of what I actually want to accomplish, though. That helps a heap!

I'm using IXMLHTTPRequest of MSXML4 to obtain an XML file from a server. First time I query I get the correct content, but following queries seem to take the data from the local cache. I poll a newsfeed, so it's important my data is up to date. Opening the newsfeed URL with IE and hitting refresh causes the cached version to be updated, and my request returns the new data. I have this behavior with my local IIS as well as a remote Apache server. How to I get MSXML to really obtain the XML from the server and ignoring any locally cached version ?
Thanks for your time,
Tim

Hello All,
Could any of you please tell me how can i return datareader from web service .
How can i serialize datareader ???????????
Regards,
Gandhi

You cannot serialize a datareader as far as I know. It doesn't implement the ISerializable interface. However, it does inherit from MarshalByRefObject so you could return a reference to the datareader from your webservice.
So you could do something like this:
SqlDataReader dr = myWebService.GetDatareader();
Just be sure to close the connection when you're done with the datareader!
Depending on your needs, you might be better of with a DataSet, e.g. if you need to hold on to the data for a while.
HTH,
Jeffry

Ok. I finally got broadband at my house. (comcast.net)
Life is goooood!
My background is i'm an outa work oracle developer who needs some
web experience to get a FRICKEN job.
I know simple ole html and the basics, but that's mostly it.
No fancy shmancy dynamic stuff like asp or cgi yet.
I don't LIKE Oracle anymore now that I've met my new love: SqlServer2000.
I've got VisualStudio.NET enterprise.
I've got XP home edition on a 833 MHz pentium3 with plenty of ram n disk.
What should i do to play around with a database backed website?
I'm just gettin my feet wet w SqlServer2000 n C#.
I've done plenty of Oracle PL/SQL n C and C++ on windows.
Where should I go today???
IIS? Apache? Can Apache talk to SqlServer?
I don't like vb (no offense anyone) so I'd like to stick w c# asp.net
if that's possible...
Should i bother lookin for a web hoster that'll let me do full
asp? Or try to wing my own lil pc into a web server.
(dynamic ip address, not sure how dynamic).
Any recommendations?
Thanks for ANY help...
