Hi there

I have a index.html file that contains 3 frames. I would like the header frame to update first, then the navigation bar frame and then the content. At the moment it seems like they are loading simuteonously?? and the "content" which is the smallest of the frames appears first. Is there a method to load the header frame, then the next etc. without slowing the upload process?

ok dude..basically what you need to do is load the next frame from the previously loaded frame...

so lets say that you a have a frameset composed of 3 frames.. something like:

<br />
<frameset rows="100,*" border=0><br />
    <frame src="top.html" name="frame1" border=0 scrolling=no><br />
    <frameset cols="50,*" border=0><br />
        <frame src="blank.html" name=frame2 scrolling=auto><br />
        <frame src="blank.html" name=frame3 scrolling=auto><br />
    </frameset><br />
</frameset><br />

so you have frame1 through frame3. Notice that frame2 and frame3 have as a src a blank.html (I'll explain why in a bit).

since you want that frame2 loads after frame1 does... you will place the following code in top.html (the file in frame1)

<br />
<html><br />
<head><br />
<script language="JavaScript" type="text/JavaScript"><br />
<!--<br />
function MM_goToURL() { //v3.0<br />
  var i, args=MM_goToURL.arguments; document.MM_returnValue = false;<br />
  for (i=0; i<(args.length-1); i+=2) eval(args[i]+".location='"+args[i+1]+"'");<br />
}<br />
//--><br />
</script><br />
</head><br />
<br />
<body onLoad="MM_goToURL('top.frame2','left.html');return document.MM_returnValue"><br />

you will do the same thing in left.html (the second frame)...but changing only the target frame and the file to load:

<br />
<html><br />
<head><br />
<script language="JavaScript" type="text/JavaScript"><br />
<!--<br />
function MM_goToURL() { //v3.0<br />
  var i, args=MM_goToURL.arguments; document.MM_returnValue = false;<br />
  for (i=0; i<(args.length-1); i+=2) eval(args[i]+".location='"+args[i+1]+"'");<br />
}<br />
//--><br />
</script><br />
</head><br />
<br />
<body onLoad="MM_goToURL('top.frame3','index.html');return document.MM_returnValue"><br />

thats pretty much it. Keep in mind that every time you reload the site, the process will repeat itself.

hope it works.

luck,
Jon

FileSystemObject Problems

Dion15-Mar-03 15:21

15-Mar-03 15:21

I'm trying ot use the ASP FileSystemObject to create new folders in my web application and unable to do so.

The FolderExists call seems to work but when the CreateFolder function is called the application locks up. I've tried giving full access to iuser and shared the c:\ drive as well as shutting down zonealarm and norton (Only while offline) but nothing seems to help.

This is the simple code I'm trying to use.

Any hints would be appreciated.

<%

Dim objFSO
Set objFSO= Server.CreateObject("Scripting.FileSystemObject")

'Create the folder
If Not objFSO.FolderExists("C:\newFolder") then
objFSO.CreateFolder("C:\newFolder")
End If
%>

Usually this happens when you have Norton Antivirus installed with Script Blocking enabled (even if NA is disabled by itself). So you should disable the script blocking in Norton to be able to use FileSystemObject. To read more about this problem, here is the link:

Question about ONSELECTSTART event of HTML body.

George215-Mar-03 1:45

Hi, everyone!

I have referenced a lot of materials but still do not
understand the meaning of the event.

for example,

--------
<BODY scroll=no ONLOAD="initialize()" ONSELECTSTART="return false" TOPMARGIN="0"

LEFTMARGIN="0" topmargin="0" marginheight="0" marginwidth="0" class = "color1">
--------

Who can give me a simple explanation about the meaning and function of
ONSELECTSTART?

Thanks in advance,
George

Basically it lets you catch the begining of the onselect event of many elements on the page. Select happens when you click on an element or navigate to it (using tab, shortcut keys, autofocus etc.)

So you could catch the begining of the select event of a hyperlink, check something else and then return either true or false to let the rest of the event through or cancel it (maybe the person could only select the hyperlink if they have typed in something in anothe text box for instance.)

Frankly though it sounds overly complex and I have never seen it used (or even heard of it) before today. OnClick/OnSelect etc. give most of the control you need.

I think the more important question is: Why do you want to know about ONSELECTSTART and why are you putting it on the BODY element? What is your requirement?

I have seen it (onselectstart="return false;") used to disable the unwanted event of having selectable text disabled.

For example:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemDataOleDbOleDbConnectionClassctorTopic2.asp[^]

MSDN uses it in their tree view of the MSDN Library. They allow you to select any of the content in the main frame but want to ensure that their lovely tree design is not messed up with having parts of it selected ... at least that's my viewpoint of its usefulness ... I'm sure there could be plenty of other reasons to use it elsewhere too.

Database connection

TPN15-Mar-03 0:26

TPN

15-Mar-03 0:26

I develop a web site by ASP and SQL Server.
The connection to SQL Server is stored in the Application object : Application("Connection"). (That database connection is established in the global.asa). I use only this connection for all ASP pages. But I am so confused that what will happen if there are many pages (which are accessed from many clients) use the same connection at the same time? And can I use the Application.Lock...

Please explain me if my way is right ?

Re: Database connection

Paul Watson16-Mar-03 22:34

Paul Watson

16-Mar-03 22:34

Don't do it that way is the simple answer.

There are two ways you should do it, based on the traffic and resources of your site.

First way is for small sites where scalability etc. is not as important and where you cannot afford to do things the second way. This is to open the connection each time you need it and then close it right after you have used it. Open late, close early.

The second way is to use a COM component which has a pool of database connections. Your ASP code then never talks directly to the database, but rather speaks to your data access layer which is in the COM component and which manages the connections. There is a very good article on pooling right here on CP (but I can't find it. Just look for database connection pooling or thereabouts.)

Application.Lock is probably a bad idea because you then have to managed it very carefully and have a transactional system. What happens if an error occurs after an Application.Lock but before the unlock? Your error handling has to be very good and really it sounds like a nightmare.

Thanks so much. But please show me the risks when only one database connection was use for all pages. I'm using only one database connection for my web project but I cannot find errors...I don't know when???

Can I use the connection pooling which is provided by the ODBC 3.0 through ADO (without COM, as our ealier discussion)?

Suppose that we use the connection pooling technique and SQL Server is licensed for 5 clients (maximum 5 connections at a time), what will happen if there're more than 5 web-clients request at the same time?

You have to use a combination of 3 things:
- database;
- session vars;
- cookies

You can use cookies to leave some portion of the data in the users computer but for a session you wouldn't have to rely on persistent cookies. You should use per session cookies (see this option in Internet Options in IE) just to store an SID (session id) and the rest of the variables should be stored in the db. In every page you will get the sid, query the db and get all the variables you need for that session. It's even secured this way.

Hi,

a few ways you can do this... not sure if you wanted to do this server side or client side so here's both:

for server side (asp):
Request.ServerVariables("HTTP_REFERER")

for client side (javascript):
document.referrer

both of these will return a string which will look something like this:

Entertainment News Service

I am building a site for a DVD rental company and I am wanting to have entertainment news stories (like a mini-blog) on my front page with a short blurb, the date, and a link. Does anyone know of any entertainment news web services? I would prefer a free one, but let me know of any that you would recommend even if they cost money. I can just write a web client and parse a page using regex, but it's harder that way and destined to fail as soon as the news web site I'm pulling from changes.

Any suggestions?

Hi,

I think whatever you are saying is not a Open Relay, if I am right. You are sending mail through the SMTP servers with the mail account for which you have registered for yourself.

Perhaps for definitions of Open Relay and Third Party Relay, please check this URL.

Hi
I have a problem with font sizes on my webpage. At the moment I'm using
which shows fine on my browser, but way too small on others (all viewed on 1024 x 768 resolution). If I set the size to '2', the font is way too big on my browser, but OK on other browsers.

And don't want fixed font sizes, so what is the best option?

I know this sounds obvious, but...
have you checked the Text Size you are using on your own browser?
(in the "View"/"Text Size"... menu in IE)

It sounds as though your own browser is set to Text Size "Large" or "Larger".

Another possible cause...
are you using a non-standard font, which may be installed on your own system, but not on anyone else's? The font could be being substituted for one that displays "smaller" given the same font size.

Hope this helps!

On my web pages, I tend to match the "normal" font size to that of the windows font. So I guess it doesn't matter what screen resolution other people are running because it would appear to be "normal" to them anyway. There will always be people that changed the fonts to the windows menus etc to what they want and as good a mind reader that I am, I just don't know what the user does with the fonts on their system. And I think at least if I set the fonts of the website similar to the standard system fonts then it would suit the majority of users.
