I've read\viewed some articles about ASP\ASP.NET and I want to learn something about it.
I have WinXP Professional with IIS on my machine. I'm connected to Internet via LAN (linux).

Should I have any software beside VS.Net. I heard that there are some problems when the server is under Linux control. I only want to write and test ASP apps on my computer.

Confused | :confused:

You don't have to be even connected to Internet if you want to develop ASP/ASP.NET. Your computer will be a server by itself, with domain name "localhost". So it is doesn't matter how you are connected to Internet.

Whats the general synopsis on the tabular data control...?

I believe it uses the ADO activeX control to process and bind the data to the HTML elements, but I feel if-fy using it for a client...they ain't paying me enough to do it in Perl (only pl scripts are allowed to run on there server)

it's not really required to have the data processed server side then sent back to the browser. Really I want just a quick fix and the TDC sounds comfy...but I wanna know where this control stands in the near future...?

I'm not up for storing a large client side array w/ JScript and adding searching/sorting this way either...maybe it would be more cross borwser compatible, but I think NS has a plugin that allows TDC to work it's magic.

Anyways...whats your opinion on the TDC considering the above...?

There are plenty of people here that can and are willing to help with an issue, but you have to be more specific. For instance, how are you broadcasting messages right now?

Generally with chat programs you know the users that are in the room. Instead of sending a message to all the users, just single one out. That's about all I can say until you give more details.

display x amount of characters

1-Mar-02 4:32

In my Access database, i have a field called REVIEW. It contains many characters and sentences. What I wanted to do is to only display x amount of characters. Well, that would result in cutting half of a word if 150 characters happen to stop at said a word called "insurance". anyway, whats a better way to do this??? Can I only display the first sentence, when it stop at the mintue they see the "." (period)?? thanks

jlo

<%= left(rs("review"), 150) %>

Try using this function...

Function TruncWithChar (data, length, char)
	' if we don't find the char, just return the string
	If Not InStr(Left(data, length), char) > 0 Then
		TruncWithChar = Trim(Left(data, length))
		Exit Function
	End If

	' check for the char
	If Mid(data, length, 1) = char Then
		TruncWithChar = Trim(Left(data, length))
	Else
		' it's not, find the last position
		x = InStrRev(Left(data, length), char)
		TruncWithChar = Trim(Left(data, x))
	End IF
End Function

Here's an example call you can use with the sentence situation...

TruncWithChar("Let me tell ya story 'bout a man named Jed.  Poor mountaineer", 50, ".")

Chaps,

I have this ActiveX control that we use rather extensively on our intranet to display test results, is it possible to use ActiveX controls on ASP.NET or would I have to make it into some kind of web service? Eek! | :eek:

Thanks for any response

I have not test it but I know at least you can use HTML code in ASP.NET,so you can use OBJECT tag.

DB Connections in .aspx pages

Hi,

I have developed a set of .aspx pages that interact with a database. I have put the same database connection string into every page, but this isn't ideal for obvious reasons. Is there any way I can specify the database connection string outside of the .aspx pages or somwhere that all pages can access it from?

Cheers.

Dave.

I have developed a web application that will only allow users to view pages once they have logged in. When I create a .aspx page I can call this will give me the current User or ID that is logged in:

Dim ClientID As String = User.Identity.Name

This works fine when I try and call the same line within a (.ascx) control page I get an error. Why can I not call the logged in user from a .ascx control or can I?

I also save a cookie at the login page but I also don’t know how to retrieve the data from within a (.ascx) page.

Response.Cookies("ClientID").Value = ClientId

I need to merge data in a database and have the application print out and look exactly like the current paper version. I have looking into generating a pdf file using XMLPDF, but to layout the entire app in xml might be too time comsuming. Does anyone know of any other solutions out there for creating a printable doc that is as good as the original paper app?

We have used an ActiveX product from Data Dynamics called Active Reports which allows the user to print the report from the web. This component also allows you to create PDF's. One of the great features from this company is they have a royalty free plug in for the end user to download. This is great when comparing licensing prices from companies like Crystal Reports. Hope this helps. Smile | :)

ASP Question

When submitting a form...how can your compare the server time with the client time. If there is a restriction of 48hours.

The form must be submitted where as the people on the other side have time to set the request up...there needs to be a minimum of 48 hours. If the form is submited under that 48 hours...how can you return false or alert user...insufficent amount of time, please resubmit and adjust your time.

Thanks Lewis Ostrander

A couple things come to mind:

1) You could cookie them when they first get the form. Stick the server time and date into a cookie, then when they submit the form you can check cookie, compare it to the current time on the server and take any actions you need.

2) Use a database to record time / date of the user's first visit, then when they try to submit the form, check how much time has passed.

I'd go with option 2) I think, since it's not dependent on the browser accepting your cookie. Unfortunately you will need to identify the person filling out the form before you send it to them the first time.

Best,
Bill

PHP problems, please help

Cam26-Feb-02 18:27

26-Feb-02 18:27

Whenever I try to access a file by URL, for instance, like this:
$size = GetImageSize ("http://www.php.net/gifs/logo.gif");
or with a fopen() command, I always get this error:
Warning: php_hostconnect: connect failed in openurl.php on line X
Warning: fopen("http://www.binaryuprising.com/index.htm","r") - Bad file descriptor in myscript.php on line X
What gives? If I look at the php options on the server, it says:
allow_url_fopen = 1
That would seem to me to mean than opening of remote files is enabled. Any ideas?

Hai,

I have installed the .NET framework redistributable on a
machine. And I installed my ASP.NET web application that I
created. When I ran the application none of the ASP.NET
controls appeared. Can you tell me what I am missing?

I also found that in my development machine there is an
ASPNET user account created. This is not created in the
machine that I am testing (in which I only installed .NET
framework redist!!).

My project beta demo is broken because of this. Any quick help will be greatly appreciated. Smile | :)
