You can't program a database in javascript. You can use javascript in the web page to make the user-experience better, but the data handling needs to be done on the back end with something like asp, .net, php, perl, etc.

I have an order form in ASP. One order can have many products. With so many products it's impossible to put that on a combo. So the user must type product code. That's OK for the user. How to validate so that the user didn't enter two same products on one order. I tried using functions which access Array. So when the user chooses a product it will be sent to the Array, and so on. Is there a better way for this? I think this is dangerous because I have to declare an Array and delete it repeatedly. Thanks.

Is it possible to change the approach of how the user selects an item? If there are too many to put in one list, perhaps you can drill down through categories and sub-categories. Take a look at a website like home depot. They sell thousands of items, but they don't list all items on any one page. You have to go into a department, select a category inside that department, and there might be sub-category after sub-category (nearly infinately in terms of possibility) until you find the product itself.

Thanks. I can't drilll through categories and sub-categories. All the same type. I'm planning to build a class for the list.

hi
i want to know which one is better for web programming?
.NET or PHP ?
thanks
|
|
|
|

personally, i prefer php.
pro's:
it's faster, has more control over the layout, appearance and general look of the page. it also connects to a multitude of databases, and has a huge function set.
con's:
it isn't object orientated, it's nothing like windows programming (if that's what you're used to), you generally have to do a lot more to get things going.
in terms of asp.net,
pro's:
it's very much like windows forms programming, you don't have to know much about html or javascript or anything else to make your site work
con's:
it's slow, it has very little control over the layout and appreance of the page, it can initially only connect to ms sql server, it only runs on iis, it's cumbersome, it makes heavy use of javascript - meaning that it doesn't work in all browsers
i prefer php due to the fact that i have greater control over the pages and i don't have to worry about licensing costs when connecting to a number of the databases. i can also set up a server anywhere, on windows or linux, which means that no matter what environment i'm in, i can still develop my php sites/pages.
the choice depends on you. there are pro's and con's to both. imho, php's pro's outweight it's con's, and i personally think that some of it's con's are actually pro's, and that's what sells php for me.
universal rule of thumb applies tho: ymmv - your mileage may vary

Soapbox! 
Not everything you wrote is true. E.g ASP.NET isn't slower than PHP. Btw, is PHP finaly compiled language? For layout/browser support - you CAN have FULL control over what you send to browser.... list goes on, I'd really prefer other place for this discussion.
For your defence, well, it wasn't easy question.

Been there, done that; refused to do anything in PHP again. FYI I moved from PHP to ASP.NET, not that I've been using ASP.NET and tried PHP once.
Use your PHP. No problem. Just don't talk black about ASP.NET... unless you say truth  Like if you said ASP.NET has slow first respose, because it JITs whole thing... For really small apps ASP.NET can be slower, because it's quite overkill. But it's like MySQL vs. MSSQL... First may be slower for small tasks, but second run out of gass for bigger tasks. That's waht you meant IMHO.
For what I could get angry is your statement that you don't have full control over page output. That shows you don't know ASP.NET, or that you are sane enough not to render controls by yourself. For example, my homepage runs on ASP.NET, and it's *almost* valid XHTML1.1 Why almost? Well, because of stupid designer (but that's not ASP.NET fault!) and my own laziness. No constraints from ASP.NET side. Of course, it means some more work and you are not able to use most of web controls (which is one more advantage of ASP.NET). But how does it differ from PHP? Still, you get huge advantage (.NET framework, codebehing) on back-end. I know PHP templates, but still too bad when compared to codebehind.
The bottom line is, ASP.NET is more like platform, you can use many languages (I know people who are working on PHP.NET, btw) etc. So arguments like it uses lot of JavaScript is... hmm... not full truth.

ASP is BASIC syntax...
PHP is C syntax...
Do the math 
It's frustrating being a genius and living the life of a moron!!!

WTF? he's talking about .NET... you can have C# syntax... or MC++ if you really want or even PHP[^]!  That's it.
p.s no, I am not paid by Microsoft to bash PHP I just make my living with ASP.NET... you do the math

Regarding the debate of which one is faster, you have to realize that people are comparing their own personal experiences. This is not a controlled situation. You could have a very simple program written in a horribly slow language versus a complex program written in a fast language and the simple program will out perform the complex one just because it has less to do. You could also have a complex program running on a fast server out performing a simple program on a slow server...There are just too many variables.
One thing to keep in mind is .net will create a virual compiled version of your application on hand. It is compiled at the first run-time and is kept until the .net file is updated. This means that you have a compiled program going up against a .php file which has to be interpreted each time it is run. This is the step which will always make .net faster than php WHEN EVERYTHING ELSE IS EQUAL.
Speed aside, you are asking which is better for web programming. In my 21 years of programming, I've learned there is no better language. There is just better use of the one you choose. Pick one and be good at it and you will always be better than people who half-ass their way through "the newest thing" - if you know what I mean.

Pliz help me with the hi-lighted string sql. It shows that there is an error by underlining. But i can't see any problems...

Dim rs<br />
<br />
'Read in the record number to be updated<br />
lngRecordNo = CLng(Request.QueryString("password"))<br />
<br />
'Create an ADO connection odject<br />
Set adoCon = Server.CreateObject("ADODB.Connection")<br />
<br />
'Set an active connection to the Connection object using a DSN-less connection<br />
adoCon.Open "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath("Projectdb.mdb")<br />
<br />
'Create an ADO recordset object<br />
Set rsProjectdb = Server.CreateObject("ADODB.Recordset")<br />
<br />
'Initialise the strSQL variable with an SQL statement to query the database<br />

sure, obviously quotes are on wrong places. IIRC symbol & is in VB used for string concatenation merging. It should be like:
strSQL = "SELECT Table1.studentid, Table1.password FROM Table1 WHERE studentid=" &studentid& "AND password = "+&password&
However, this code is still far from being perfect. Read Colin's article about SQL Injection[^]

I want to put my DLLs in the application program directory but when I do that the IIS does not find them. The only place that I can place them is in \WINDOWS\SYSTEM32. I tried updating the PATH environment variable under the administrators account but that didn't do the trick, probably because IIS uses a different userid.
Any ideas on how to update this?
Thank you,
Glenn

Hi,
I'm writing a program in C# using .NET 2003 on IIS 6.0 and Windows/2003, that is calling some legacy code written in a .DLL. What I am seeing happen is the output files it's creating is in C:\WINDOWS\system32\inetsrv.
I do not want the files in this directory but in the application directory. I tried modifying the legacy code to specify a path but it choices to ignore it. How do I change the default directory for this application only.
Thank you,
Glenn

if you just put the gif on a page, does it animate -- i.e. is the gif itself the problem?
have you got an onclick event on your submit button?

I'm new to JS, but I saw the sample code for the panelbar and it was something I've been looking for. It works ok locally, but I took the same code and threw it up on my website and it doesn't work there. In my local editor, I get an "error on line 20, object expected" on the following line:
var objTmp;
I don't know what to do with it. Currently, it's at:

no, you uploaded it to Js foder, and you referenced it as js folder in your markup. Your server is case sensitive. Rename folder or change your markup, then it should be ok.
