A friend has asked me to help with a business idea to sell files over the internet (like the mp3 download sites). Obviously they could just email the files on payment received but I would like to find a better solution.
I just don't know where to begin, can anyone point me in the right direction?
Should I try to find a application someone has already written which can be adapted?
Any thoughts would be really usefull. 
Thanks,
Ali

Hello helpfull web guru who will hopefull know what is wrong!
I have a web app, that builds a graph according to survey data entered over several pages. The answers to these questions are saved to an SQL database. After the last question is answered, the page calls the following class:

End Class
Which should draw the image, and save it to the HDD, and return the calling page with a GUID filename.
My problem occurs if two users are doing the test simultaneously. The class keeps drawing the first image over and over, completely ignoring any new parameters passed into the constructor?
Please help me if you know what I am doing wrong? The code below is the calling code on the page:
Private Sub DisplaySpider()<br />

All my dear friends
Im a new programmer. I have finished a webbase ASP.Net+C# project. I want to publish it on my LAN(2 windowXP PCs linked togeter with a roster). I can use IE to browse my webbase application pages on the computer that I used to developed the project.(I open IE, input the address "http://localhost/VParking/Main.aspx") It works for the computer.
But how can use IE to browse the project from another computer?
I tried to shared my Inetpub floder. and open the IE from another computer and input address "\\MING\Philip's (C)\Intpub\VParking\Main.aspx". but it doesnt work in this way.
Would anybody give me hit to solve my problem?
Thank you very much

Try http://MING/VParking/Main.aspx and, if it can't resolve that hostname, then try http://<IP Address of MING>/VParking/Main.aspx.

Hello,
I am trying to build a webpage which allows my users to search multiple seach engines asynchronously. The page will contain 1 input textbox and a submit button. I want the search engines to be in variable format so I can pull from database or datatable. After a user enters a search value into the texbox, I want a spinning search indicator for each instance of the search engine source to show to the user. Once one of the search engine source returns a result I want to update the loading indicator to a different image and also show the results on a datagrid below the progress indicators. I was able to get one instance to work with the indicator and results but I can't seem to get it to work for multiple progress indicators and results. Thank you if you can help.

Well, you're probably doing something wrong.

Well, I am trying to do this in C# under .NET Framework 1.1 and on a webform.
Here is what I would like to accomplish...
<%@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="false" Inherits="portal.WebForm1" %>
<title>WebForm1
texbox...
button...
datagrid1...
datagrid2...
Here are my questions....
Lets say I have 3 sources (www.google.com, www.yahoo.com, and www.msn.com), they will show up on datagrid1 when the page load like this...
Source Status
www.google.com None
www.yahoo.com None
www.msn.com None
As soon as the user enters a value and click Search, this is how datagrid1 should look
Source Status
www.google.com Searching...
www.yahoo.com Searching...
www.msn.com Searching...
And as soon as one of the Sources return any results or error it will update the Status for that Source accordingly. It will also populate the results in datagrid2 like this...
datagrid1:
Source Status
www.google.com Success
www.yahoo.com Error
www.msn.com Searching...
datagrid2:
Source No. Results
www.google.com 100
www.yahoo.com 0
I hope this makes sense. I search all over but can't seem to find a way to do this. Any help is greatly appreciated.

IE on Windows XP SP2 shows this yellow bar on the top of the webpage if it has an activex control. I want to show a message on the webpage to the end user to click on the yellow bar and install AX control, but I would like to show the message only if the client OS is Windows XP SP2. Is there a way to detect this from either the http headers, or user agent string, or from the javascript in the web page? I looked at the user agent string, but I dont see anything that tells you it is from Windows XP SP2.
thanks!
|
|
|
|
|
I think you must use JScript, and if you do, the yellow bar will show up because you are trying to access sysinfo. I think you should view the message anyway, as most xp users have sp2.

After a few evenings of doing tutorials and trying things out, I just encountered my first reallife .NET problem. It concerns dynamic databinding of a Repeater control, using C# and Visual Studio 2005.
For the purpose of binding a number of XML datasources (RSS feeds) to multiple Repeater controls, I made my own implementation of the ITemplate interface :
<br />
public class RssTemplate : ITemplate<br />
{<br />
static int itemcount = 0;<br />
ListItemType templateType;<br />
string title;<br />
<br />
public RssTemplate(ListItemType type)<br />
{<br />
templateType = type;<br />
}<br />
<br />
public RssTemplate(ListItemType type, string t)<br />
{<br />
templateType = type;<br />
title = t;<br />
}<br />
<br />
private void TemplateControl_DataBinding(object sender, System.EventArgs e)<br />
{<br />
Literal lc;<br />
lc = (Literal)sender;<br />
RepeaterItem container = (RepeaterItem)lc.NamingContainer;<br />
lc.Text = "<a href=\""; <br />
lc.Text += XPathBinder.Eval(container.DataItem, "link").ToString();<br />
lc.Text += "\">";<br />
lc.Text += XPathBinder.Eval(container.DataItem, "title").ToString();<br />
lc.Text += "</a><br />";<br />
}<br />
<br />
public void InstantiateIn(System.Web.UI.Control container)<br />
{<br />
Literal lc = new Literal();<br />
switch (templateType)<br />
{<br />
case ListItemType.Header:<br />
lc.Text = "<b>" + title + "</b><br>";<br />
break;<br />
case ListItemType.Item:<br />
lc.DataBinding += new EventHandler(TemplateControl_DataBinding);<br />
break;<br />
case ListItemType.Footer:<br />
lc.Text = "<br />";<br />
break;<br />
}<br />
container.Controls.Add(lc);<br />
itemcount += 1;<br />
}<br />
}<br />
Now I want to loop through a collection of XML urls, fetch the content and bind each dataset to a different Repeater control (see code below). The problem is that the Databind() function, which should bind all datasources to their corresponding controls, binds every control to the first Datasource. I end up having multiple copies of the same RSS items on my page.
I'm sure it's something very trivial I'm overlooking here or it might be that my approach is wrong altogether, but if someone could push me in the right direction here, I would be very grateful.
<br />
OleDbDataReader dtr = cmd.ExecuteReader();<br />
WebFetch wf = new WebFetch();<br />
while (dtr.Read())<br />
{<br />
XmlDataSource xmlds = new XmlDataSource();<br />
xmlds.Data = wf.fetchURL(dtr.GetString(2));<br />
xmlds.XPath = "rss/channel/item";<br />
<br />
Repeater rss_repeater = new Repeater();<br />
rss_repeater.DataSource = xmlds;<br />
rss_repeater.HeaderTemplate = new RssTemplate(ListItemType.Header, dtr.GetString(1));<br />
rss_repeater.FooterTemplate = new RssTemplate(ListItemType.Footer);<br />
rss_repeater.ItemTemplate = new RssTemplate(ListItemType.Item);<br />
RssPlaceHolder.Controls.Add(rss_repeater);<br />
}<br />
dtr.Close();<br />
DataBind();<br />
As stated above : why does DataBind() bind all instances of the Repeater class to the same instance of XMLDataSource, where it should bind (in my opinion) to different instances of XMLDataSource?

Well, I fixed my own problem by accident, but I can say I was quite surprised by the solution. Not to say that this DataSource class seems to me, coming from a C++ background, rather strangely implemented.
The solution for my problem was : initialize the ID property of the datasource instance and it will be a different instance! I now have different repeater controls bound to different datasources, instead of having them all bound to the single first datasource that I created. So doing
DataSource ds = new DataSource()
doesnt create an instance (yet) with its own address space, but
ds.ID = "some_unique_name";
does!
Anyone else thinks this is rather odd? I mean, just imagine you were me, having worked with OO oriented languages for more than 10 years and coming across this seemingly new approach to class instantiation.

ASP.NET uses the ID of a control to keep track of it during each postback. The control's ID is used to identify the control's serialized information. Without the ID, ASP.NET won't be able to reconstruct the control on the server side.

You are using SQL injection! This is not a secure way of creating a SQL command. Also, you are concatenating a date to the SQL command. This is probably causing your error. If you insist upon using SQL injection, you need to convert the date to a string and, in your SQL command, have a SQL function that converts a string to a date. Otherwise, USE PARAMETERS!

How does PHP compare to Javascript?
Are there any good books or web sites that you can recommend for learning PHP?
I'm on-line therefore I am.
JimmyRopes

They don´t...
PHP is server side open source cross platform
Javascript is client side
They have strengths and weaknesses but do mix well.
PHP at version 5 is a mature OOP language and I use it to implement business logic & database patterns over a MySQL database serving pages with embedded Javascript to handle UI patterns (thanks yahoo btw)
A good book? Unusally I think the dummies PHP book is a good place to start (let the flames begin)
Is this the first PHP question on CP
And why am I answering 
Hope this helps?

PHP can be used on the client side, although it's an unusual use. JavaScript is used on both server and client side.

true, but didnt want over complicate things and as the most popular language of all time Javascript doesn´t need much promotion. So I thought giving PHP(5) a shove in this august site might be fun if a little like shouting into the wind
wikipedia and www.devarticles.com have good info on Javascript for the full story...
php.org has what else you might need too...

Hi, I am currently trying to complete a 90% working Intranet site for my company and the developer left a long time ago.
The site has been developed with ASP.net and C# both of which I'm not familar with but trying to piece my way with my J2EE background.
The main issue I have is that the site was supposedly developed with security features to restrict access to pages / parts of pages based on the users' AD Group Membership.
The developer had the following in the web.config file
<configuration>
....
<appSettings>
<!-- internal security to Active Directory group mapping -->
<!-- all mappings are in the format:
<add key="[internalRole]" value="[Active Directory Security Group]" />
-->
<!-- Standard user groups -->
<add key="iUser" value="OurDomain\Domain Users" />
<add key="iUserIT" value="OutDomain\IT Dept" />
...
<configuration/>
However nowhere in the rest of the application with code or config files can I find any reference to anything such as iUser, iUserIT etc etc.
The config file shows that Windows as opposed to Forms based authorisation is used and I have been searching the web for tutorials and found that "Roles" can be used to restrict access to a particular directory / file by using a construct as follows,
<location path="myPage.aspx">
<system.web>
<authorization>
<allow roles="AdminRole" />
<deny users="*" />
</authorization>
</system.web>
</location>
I have a number of questions :
1) If I can define as above which Role can access each resource, how/where do I define which windows Group pertains to each Role?
2) Is there a simple way of using the Users windows account to look for a particular Group, ie so that I can stick a function at the head of certain pages to allow / deny access to content based on their AD Group membership.
I'm sure this should only be a 4-5 liner but I haven't been able to find anything so far.
Any help would be greatly appreciated,
