asp.net in vb.net project

alhubo — Thu, 28 Jan 2010 13:47:24 GMT

Hi, I have been developing a home automation project for my dissertation written in visual basic.net and using an USB input/output interface board to interact with the real world. The design itself is quite crude but it is just really a proof of concept.

The project so for has been developed purely in visual basic as that is what I know, however a new requirement is that I need to present this also with a web based element, whilst the existing Visual Basic form still runs.

That may sound a bit confusing but basically I want a system that can be fully controlled locally (ie on the PC the usb device is attached to) using a visual basic form. But want some limited features also available through a web browser (such as just switching light on or off) so control of the home can be done on the move.

Thanks in advance for any advice people have to offer as I have done a fair bit of searching around but am still at a loss.

Searching A String, For A Match From Another String

mangopalaya — Tue, 11 Aug 2009 07:46:09 GMT

So what I have is two strings.. Each string is a comma seperated value of two digit states. Like this

String 1:
"NV,CA,AZ"

String 2:
"ND,HI,CA"

What I need to do, is write some C# to check string 2, for a match in string 1. Meaning, If a state is listed in String 1, it should not appear in String 2. I have used "foreach" statements, but only for list boxes. I can seperate the strings, but am having an issue writing the code to compare the two. Here's what I got so far, it will check the first thing in each list, but will not go onto the second or third? How can I change the int inside String1[0] to +1 for every item in it's list?

Edit:
It would be awesome if the code could find the position of the match in the second string, and remove it. So if it finds CA from String1, in String2, it would remove it from String2.
1. string[] String1 = LabelAllStates.Text.Split(new char[] { ',' });
2. string[] String2 = LabelAllCountyStates.Text.Split(new char[] { ',' });
3.
4. foreach (String myCountyList in String1)
5. {
6. if (String1[0] == String2[0])
7. {
8. // Detected a match, therefore I fail validation
9. }
10. else
11. {
12. // No match found! Good job!
13. }
14. }

Network OS /Real Time OS

MonicaButter — Wed, 07 Oct 2009 06:43:56 GMT

A network operating system (NOS) is a computer operating system .system that is designed by Professional Web Design companies primarily to support workstation, personal computer, and, in some instances, older terminal that are connected on a local area network (LAN). Artisoft's LANtastic, Banyan VINES, Novell's NetWare, and Microsoft's LAN Manager are examples of network operating systems. In addition, some multi-purpose operating systems, such as Windows NT and Digital's OpenVMS come with capabilities that enable them to be described as a network operating system.

A network operating system provides printer sharing, common file system and database sharing, application sharing, and the ability to manage a network name directory, security, and other housekeeping aspects of a network.

A real-time operating system (RTOS) is an operating system that guarantees a certain capability within a specified time constraint. For example, an operating system might be designed to ensure that a certain object was available for a robot on an assembly line. In what is usually called a "hard" real-time operating system, if the calculation could not be performed for making the object available at the designated time, the operating system would terminate with a failure. In a "soft" real-time operating system, the assembly line would continue to function but the production output might be lower as objects failed to appear at their designated time, causing the robot to be temporarily unproductive. Some real-time operating systems are created for a special application and others are more general purpose. Some existing general purpose operating systems claim to be real-time operating systems. To some extent, almost any general purpose operating system such as Microsoft's Windows 2000 or IBM's OS/390 can be evaluated for its real-time operating system qualities. That is, even if an operating system doesn't qualify, it may have characteristics that enable it to be considered as a solution to a particular real-time application problem.

In general, real-time operating systems are said to require: multitasking, Process threads that can be prioritized and a sufficient number of interrupt levels

Real-time operating systems are often required in small embedded operating systems that are packaged as part of micro devices. Some kernels can be considered to meet the requirements of a real-time operating system. However, since other components, such as device drivers, are also usually needed for a particular solution, a real-time operating system is usually larger than just the kernel.

xml programming and vb.net

tunsten — Tue, 21 Jul 2009 05:56:04 GMT

Hello guys

I am vb.net beginner developer majorly on ASP.NET.

Can anyone help me on how to I include header information before the main body/content of an xml file, where the header will be read from the same file. For example, I want to have company's name, address, phone, document print date in the head section before displaying the list of the customers (both the header and the content is contained in single a text file).

Secondly, I want a user to select the text file (which must conform with the format to be used to display the xml file) from his/her system directory and display the path on a textbox before converting it to xml file. How do I go about it?

Your prompt response shall be highly appreciated.

Thanks.

Response.Write vs. Document.Write

daveofgv — Mon, 28 Dec 2009 12:18:52 GMT

Can anyone explain the difference between:

[code]
Response.Write("Hello World")
[/code]

vs.

[code]
Document.Write("Hello World")
[/code]

Also, why would you use those when you can just place a label on the page and use the label text property to fill in what you want????

Thanks in advanced

Manipulate XML from a third party connector

Axiom70m — Tue, 22 Dec 2009 10:54:45 GMT

Hello,

I hope this is the right place for this question that is bordering me for quite some time now.

I'm building an extranet which connects to a connector like this:

strOutput = myConnector.GetData("COMP", "Username", "Password", "", "Recordset", Filter)
Dim objDataSet As DataSet = GetDataSetObject(strOutput)

this set returns a lot of data with no sorting or limiting possibilities. It's very simple to load this in a gridview or dataview. That's not what i need. I need to sort the data and i.e. display the one on top or the top 10.
I want to display the results in labels or textboxes.

Can anyone explain or give me an example how to get there?

Thanks in advance.

Difference between ASP and ASP.NET

ravin — Thu, 26 Nov 2009 05:25:57 GMT

ASP stands for Active Server Pages. ASP.NET is the next generation of ASP. After the introduction of ASP.NET, old ASP is called 'Classic ASP'.

Most of the engines place added relevancy on keywords found in the name of the page, or the URL. When naming your pages, try to name your pages after your keyword phrases.
Classic ASP uses vb script for server side coding. Vb Script is not supported any more in ASP.NET. Instead, ASP.NET supports more languages including C#, VB.NET, J# etc. VB.NET is very similar to vb script, so it should be easy for old Visual Basic or ASP programmers to switch to VB.NET and ASP.NET

VB Script is a simple scripting language, where as VB.NET or C# are modern, very powerfull, object oriented programming languages. Just for that reason, you will be able to write much more robust and reliable programs in ASP.NET compared to ASP.

In classic ASP, there was no server controls. You have to write all html tags manually. ASP.NET offers a very rich set of controls called Server Controls and Html Controls. It is very easy to drag and drop any controls to a web form. The VS.NET will automatically write the required HTML tags automatically for you.

The Object Dilemma

maramusa — Wed, 21 Oct 2009 02:10:46 GMT

This must be a time old question to do with Modularisation, encapsulation and RE-USABILITY.

I have an asp.net 3.5 vb.net intranet application.

I have a Job class. i have a Client class and employee class etc etc
I am using the dataset designer, and formviews.

I have a formview for my Job object. A job has a clientID. But in my formview, when i display a job, I want to show the ClientName obviously. This can be done in the formview Edit Template, by linking the ClientID field to a datasource (or object datasource)that has the Client table, the a simple INNER JOIN to get the ClientName. Easy, no code, nice.
But I dont want to have to go to the data access layer to get the ClientName. I want to be able to call the Client object like Client.Name.

I guess I could do this with a Webservice (or WCF which i havent used yet). But this seems like a big overhead using SOAP and HTTP just to get a ClientName with an INNER JOIN. We have 100 users and the clientname will be getting accessed all the time.

I guess I could use a stored procedure, but how would I link this to my Formview to show the ClientName. When Editing or Inserting a JOB, I still want the user to be able to select the ClientName form a dropdown which is linked to ClientID. So I still need a datasource right.

LINQ ???, but

I want my Client object to be in a separate application, that any other application can access, so no need to redo the DAL everytime. Yes, Im trying to do a framework.
If the Client object has fucntion that require logic, these i would obviously use a webservice or WCF, but for simple INNER JOINs and stuff, I'm stuck at the best way to be able to call these form any other application in formviews or the like.

Thanks for any ideas

ASP.Net/VB.Net - Advice for Cleaning up my code

rathurosamal — Mon, 03 Aug 2009 02:06:47 GMT

Can someone please give me some advice on cleaning up my code a little. I have aspx pages with code_behind .vb files.

Typical head of webpage is:
index.aspx
Code:

<%@ Page Inherits="ipod_index_process" Src="index_cb.vb" Debug="true" %>
<%@ Import Namespace="System.Xml" %>

Typical code is:
index_cb.vb
Code:

Imports System
Imports System.Data
Imports System.IO
Imports System.Xml
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.Web.UI.HTMLControls

Imports System.Text
Imports System.Text.RegularExpressions
Imports System.Security.Cryptography

public class ipod_index_process

inherits page Public variable declarations...... Logic code....... Call Signature (X,Y,Z) Function Signature (X,Y,Z)

Several Functions......

End Function

End Sub

Several parts of this code are common to many other pages in my site (e.g. the declarations) or need to be used throughout the site (e.g. the Function Signature). Presently they are written out again and again in each .vb page.

What I want to do is to put the 'Public declaration' in a separate file and the 'Functions Signature' and everything in it in another.

I'm an old school VB programmer and not used to using namespaces/inheritance/classes. I'm sure this requires using classes and namespaces but I've tried to get my head around it but failed.

ASP.NET Banking Facility Website

igglepiggle — Tue, 19 May 2009 15:03:33 GMT

I've recently completed a college course in VB applications, it's really interested me and to try and extend my knowledge I'm now trying to teach myself ASP.NET.

One of the applications I wrote replicated basic banking functions, a front screen prompted for a card number and PIN with a button to continue. Once correct details were entered it moved on to a form providing opportunity to view balance, withdraw money, see a mini-statement or cancel. A third form showed the mini statement, all other functions were visible from the previous form.

This is probably the most complex of the applications I wrote, I'm now hoping to develop the application into a website to replicate online banking of the same functions. I've started with a front screen, labels and text boxes prompting for the card number and PIN, but where do I go from there?

The data is stored in a local SQL database, I'm aware of SqlDataSources and commands, readers etc but unsure where to use them. The simplest of advice would be much appreciated.

Using Sessions

Matrix101 — Wed, 22 Apr 2009 09:50:49 GMT

Hi All,

I am using specific sessions calls in my *.aspx pages and i have 2 questions related to this:

1-Is there a difference between using this type of session declaration in your aspx page?:
HttpContext.Current.Session.Item("Whatever") VS Session("Whatever")
Would this give the same information for a specific user?

2-Is using Session really User Specific data? I know you can share information using cache but is there possibilities that we have 2 different users (different browsers) that would share information threw sessions. Keep in mind that i am using SQLStateServer for my sessions

Thanks

Vista and IIS

Xarzu — Wed, 05 Mar 2008 11:05:51 GMT

Now I am using a VISTA machine. I am restarting my ASP.NET experience in a new environment. So far I have managed to set up the IIS. That was a lot easier than I had thought it would be. The next step is, I found out where the computer pointed the localhost to (c:\inetpub\wwwroot\). And so the next thing I thought I would try is to write htm files out to this location. Bad idea. It says I do not have permissions to do this. This is odd because I was sure I had admin privs. Any suggestions?

I am brand new to Vista. How do I check my privs on my own machine? I have clicked on the area in the Control Panel and it shows two users.
Both of these users have Admin Priv's, including me.

But when I try to save a file, to the C:\inetpub\wwwroot\ area I get this error:

I am wondering if there is some sort of special procedure that needs to be done in order to put a file in the location on the hard drive where the IIS will recognize it as an internet file. Maybe you cannot just simply cut and paste an HTML file. Is that true? Is there some sort of special "publish" or "submit" that you have to do on an operating system level or through some sort of special IIS software procedure?

Script Resource and the Web Resource Issues

JamTech — Mon, 26 Jan 2009 10:43:13 GMT

The Script Resource and the Web Resource files are generating intermittent errors in my application. I have been trying to chase the cause of the problem but to no avail. I notice that the “d” parameter that is passed is some how corrupted and I can’t for the life of me figure out what’s causing this parameter to be corrupted. I noticed that JavaScript code that in my application is some how getting intertwined with the hash code that’s generated for the “d” parameter.

Developing a .NET web application using VB.NET for a company

jayzinho88 — Mon, 15 Dec 2008 12:51:49 GMT

Here's the story....

I have been workinig for a company for around 6 months now, and on my CV I had put VB and .NET programming as I had done the relevant courses and attained the qualifications. My job role was not as a developer but as an administrator of another application. I have never used my VB or .NET skills in a business environment. The company began to develop a web application which would be used to calculate rebates for its customers, however the lead developer has left the company pretty much as soon as the project began and now it has fallen to me to complete it. Unfortunately, when asked in the interview about my developer skills, I played it up and said that I was fairly competent at it. Obviously, it has backfired and now I need to develop this application. I have tried to rekindle my knowledge, but it appears I have forgotten all my coding. I understand the technology behind ASP.NET, but cannot remember any VB.NET - I was never any good to begin with! Anyway, I need to have this application up and running by the end of January at the absolute latest, and what I am asking for is if there is anyone who can help me, step-by-step, to build this application? I would be extremely grateful and would accept any input about this. I cannot get out of this situation, the web application MUST be built, by me, and soon.

I have created an underlying database structure in SQL and imported the relationships into my Visual Studio project. I have added the relevant controls to the page. All I need know is the ability for them to interact with each other, read from and write to the database, and generate certain things. The application itself is fairly basic, the only problem is there are several pages which need to be able to do certain things. Again, I don't think it is difficult, but I haven't got the knowledge to be able to complete the coding.

Is there anyone out there who would be willing to help me? I would be happy to offer some financial "reward" at the end, if it is successfull, as I am very desperate to complete this application.

If you need ANY more information at all, please ask, and I will be happy to give it to you.

Sorry for the long post....

Desperately,

Jay

P{roblem when dynamically adding my user control

bigpete666 — Wed, 08 Oct 2008 12:40:06 GMT

Hi,

I'm new to asp. I have been creating a user control. It works fine if i place it in the main page. I have been trying to get it to display x number of controls depending on the value of the drop down box.

The code woked fine when i tried it with a label or text box but when i change it to my user control it dosn't. The page load event of the control fires as i can get it to do a messagebox, it wont display anything and if i try and load values in to a drop down list it says its not created yet.

Source code:

WebForm1.aspx

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="testcreatecontolsonfly.WebForm1" %>

<%@ Reference Control = "WebUserControl1.ascx" %>

confused with the looping

ashley_10 — Wed, 23 Jul 2008 20:41:03 GMT

how can you loop the records in the database with fading?
In this image:

what i want is to loop the records.. like for example, after it displays the first record it fades out and then transfer to another record in the database.. then fades out again and turn to another record and so on...

here is my vb code...

Dim x As Integer
x = 10
Do While x <= 10
If sqlreader.Read() Then
empno.Text = sqlreader.GetValue(0)
firstname.Text = sqlreader.GetValue(1)
midname.Text = sqlreader.GetValue(2)
lastname.Text = sqlreader.GetValue(3)
titlecode.Text = "Title: " & sqlreader.GetValue(4)
hiredate.Text = "Date Hired: " & sqlreader.GetValue(5)

empimg.ImageUrl = "~/images/" + sqlreader.GetValue(0) + ".jpg"

End If
x = x + 1
Loop

'code for fading
Show1.Width = "560px"
Show1.Height = "100px"
Show1.ShowType = ShowType.Show
Show1.TransitionType = TransitionType.Fading
Show1.FadingSpeed = 1000
Show1.FadingStep = 3

sqlconnection.Close()

Is it possible to use a style sheet class directly on a control instead of using inline or page-level formatting?

Popup

Shahzad — Tue, 03 Jun 2008 23:30:27 GMT

I am using JavaScript with VB.NET 2005.

Why I have to click twice to show popup, further more how to show borderless popup.

btnPopup.Attributes.Add("onclick", "window.showModalDialog('http://www.yahoo.com','MyWindow','toolbar=no,location=yes,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,width=600,height=300');")

I am new in Web based programming with VB.NET 2005 and searching for advance level articles to improve my programming in this field.

Why we have to take help from JavaScript, Is this tool do not fulfill 100% requirements.

Regards,

Shahzad
