Ok, couple of things.

First, put Response.Expires = 0 at the top of any page you want to not be cached.

Second, put some kind of login script at the top of each page you want password protected.

A common example is

VBScript

Response.Expires = 0

If Session("UID") = "" Then Response.Redirect ("login.asp")

Naturally the Login.asp page will need to put the user id into that Session variable.

This way ASP checks each time a person hits a page to see if they are logged in or not.

XML itself doesn't set any limits, but your OS or some other piece of software manipulating the file might have a size limit.

Response.Redirect("CannotEdit.aspx");

I got this error many times and I only found out that I had declared or tried to use an object which has a NULL value. So check the other lines of code in your Page_Load(May be its not the Session object that's causing this problem). See if they have any object which at any condition may fail to have an instance.

If still couldnt find it, If I were you, I would comment out lines of codes and find out where it is happening (if you dont have the debugger).

If you have debugger, find out the value of Session["canedit"] in the Page_Load.

Adding dates to a database

Xavier Shay13-Feb-02 14:33

13-Feb-02 14:33

I'm trying to create a forums site, and I would like to add a date to all posts. At the moment I have the following code:

SQLStmt = "INSERT INTO Messages (ForumID, ParentID, PosterID, Title, Body, Date) "
SQLStmt = SQLStmt & " VALUES (" & forumID & ", " & parentID & ", " & userID & ", '" & subject & "', '" & message & "', #" & Date() & "#)"
set RS = conn.Execute(SQLStmt)

Which when expanded prints something like:
INSERT INTO Messages (ForumID, ParentID, PosterID, Title, Body, Date) VALUES (22, 0, 1, 'Test', 'Test Text', #2/14/2002#)

This all works fine if I exclude the Date Field. The most descriptive error I get is:

Microsoft JET Database Engine (0x80040E14)
Syntax error in INSERT INTO statement.

Any help would be greatly appreciated

I think you need to replace # signs with '. For example:

INSERT INTO Messages (ForumID, ParentID, PosterID, Title, Body, Date) VALUES (22, 0, 1, 'Test', 'Test Text', '2/14/2002')

I'm afraid that didn't work.

But, Alas! I found the solution! I changed the 'Date' field to 'DatePosted'. I presume 'Date' is a reserved word. It took me three hours to figure that out. Oh well.

Thanks for you help anyway

Re: Adding dates to a database

15-Feb-02 20:08

Yup .. your right Date is a preserve word ... but by adding brackets [] it will work also like this [Date] .
Sometimes I use it when I have a field contain 2 words like [Date Posted]

Minimizing the Browser Window

Paul Watson11-Feb-02 23:27

11-Feb-02 23:27

How do you minimize the browser window (Internet Explorer in this case) using client side script (VBscript or JavaScript) ?

Unfortunatley the JavaScript ResizeTo method is not an option.

Also preferably not using COM components, ActiveX etc. It does run on W2K but unfortunatley WSH (Windows Script Host) is also not an option.

thanks guys.

It looks like you are out of luck on this one. It seems that MS removed all the positioning methods and properties from the window object. No more MoveTo, MoveBy, ResizeTo, ResizeBy. They really don't want you to control the window anymore - I guess it is a security thing.

Same conclusion I have come to Konstantin. The odd thing is that you can fully control the position, status, size and modal-properties of a browser window if you open it via script. i.e. You cannot control an already open window, but any window you open can be fully controlled.

ASP blocks in XML

Paul Watson11-Feb-02 22:12

Paul Watson

11-Feb-02 22:12

So who knows how to put ASP into XML elements without having to use &<test>l<test>t<test>;<test>%?

e.g.:

HTML

<?xml version="1.0"?>
<page>
	<title>BGCMS: Home</title>
	<content>
		<h1>Welcome to BGCMS</h1>
		<p>
			This is a wonderful <b>place!</b> <img src="test.gif"/>
		</p>
		<p>
			The time is approximatley <%=Now()%>
		</p>
	</content>
</page>

If I run that through an XSL processor, or even validated the XML, naturally the parser goes haywire and tells me that <% is an inavalid way to start a new element.

And yes Konstantin, it is another confusing and weird question Big Grin | :-D

So sometimes I wonder if I was born stupid, or whether my mother dropped me shortly after birth.

I figured it out and it is far easier than I imagined.

!CDATA is the way

e.g:

<?xml version="1.0"?>
<page>
	<title>BGCMS: Home</title>
	<content><![CDATA[
		<h1>Welcome to BGCMS</h1>
		<p>
			This is a wonderful <b>place!</b> <img src="test.gif"/><br/> make love not war
		</p>
		<p><%=Now()%></p>]]>
	</content>
</page>

!CDATA basically tells the XML parser to totally ignore everything within the !CDATA section. Very handy Smile | :)

is cold fusion the only way to do a login system?

Hello -- I am trying to create a web-site for our church that has a 'profiles' section for members and also has a forums section where people can leave message simliar to the code project.

Our main question is how do we set up the login system -- the company that is hosting our site has front page server extensions installed, but also has cold-fusion. from my brief beginners knowledge it looks like cold-fusion is the only way to really do a login system.

what would you all recommend? should i just go out and buy a cold-fusion book, or are their other ways to do this.

right now we are really looking for general guidance more than anything else,

If you want to use the Code Project discussion forums on your site, then you'll need to find a host that supports ASP. Ask your current host, they may already support it.

You could go either way with this. I'm sure there are plenty of Cold Fusion login systems available for free, and I know there are plenty of ASP login apps available (HotScripts.com). Personally, I would use ASP, but only because I don't know Cold Fusion.

If you have to stick with your current host, then find out whether or not they support ASP. If they do, then you can use Code Project's discussion forums. If not, then you'll have to find a Cold Fusion forum to use. In the latter case, buy yourself a good book on Cold Fusion and have fun!

If you have any more questions, please feel free to ask. Smile | :)

Thanks for your reply . . . I definitely want to use ASP -- I was just talking with somebody and they hinted that I wanted to use the Global ASA. I have done a lot of visual basic stuff, how do I make the leap to web programming. Is there a good tutorial on ASP out there?

thanks,
