Designing Information Retrieval System For Estate Agents
Dec 30, 2008
I have an assignment where I have to design an information retrevial system for estate agents. I have to be able to view the houses for sale, and delete them when there sold. I am new to vb script: Opens the Policy Details file and reads in the
'== records into the arrays (parameters) which are
'== passed back to the calling routine for
'== processing.
'== N.B. Use Sub SavePolicyDetails(...) to write
'==the data back to the file.
[Code] .....
I am creating a medical record system using MS Access 2007. the finish product will be used for a small healthcare which has only one available pc for now i ve done all required tables and some queries. What I really want to do is to design the forms where user can access information using VB 2010. I ve read tutorials online about how to connect dataabase to vb and successfully did that.
Im using visual basic 2010 and im building a program that will basically, you click on something in the list it will automatically open a .dat file pull the information that it needs, and then proceed to enter it into a box on the right. Well heres my issue i know how to do everything else but i cant seem to imitate this image, i need to know how i can make a list like this where the whole row is selectable, and the items/subitems are divided.
I´m having a problem designing a recipes program with tag(url...) support/I dont know exactly hows the best way to build the tag system, the idea I had is this, Ill try to explain it though english its not my first language, sorry about that.[code]The idea is that since I cant save memory references, at the start of the program I rebuild the references of refRecipe iterating through stTag, searching for recipes which contains its tag name. Also, when creating a new recipe, I must search if the tags exist in stTag to just set refRecipe or create a new tag.I think this systems have a lot of disadvantages because of tag name duplicity. Though its fast to show tags and related recipes, its not when creating and editing recipe tags because of all the iterations, but its the better way I found to do it.
How can I adapt this code so the user can input the password, and the username and the site for which it is entered. so the user can do this with any numer of websites, and any number of different usernames/passwords)
im currently designing a system that enables the user to input a customer record. the customer record is broken down into 11 fields: customer id, title, forename, surname, house no, town, city, county, postal code, contact number, date of registration. Problems - i need to be able to insert the new record into a file and for them to be organized into surname order (for a binary search to work) at this moment it will only sort by first field (which is unnecessary as the customer id number is generated automatically and is all ready created in order). Also, im having trouble with sorting the array that contains all the variables from the text file.
i have in my form a compobox which listed agents name, and when I choose one of them the datagridviw shows the products that agent provide to my company.
in first selection is going without any massage, but in second selection the compiler gives me this massage:Object Reference not set to an instance of an object
I'd like to know the way to get information about the Operating System (windows Xp or Windows 7) and the bit information(32 bit or 64 bit). [code]In the above code, if verInfo.Minor is 1 , then it should be Xp, but I am getting 1 for both Windows Xp and Windows 7.Is there any other way to determine the OS and the bit(32 or 64 bit) used?
I remember seeing somewhere on the net that there are classes in .Net that will return information about your computer. I know that System.Environment returns some of this information like MachineName and some other stuff. Are there other classes that will return information such as hard drive size, free and used space, total memory, used memory?
I've been assigned to do some report analysis in a management information system.My question is, do you think it's a efficient way to gather datas from SQL, with the use of basic syntax and have them manipulated through my code in VB.NET?(I'm more skilled with this kind of execution, but it takes a lot of data calling from the database)Or should I just do the advance way of inner jointing or more likely a stored procedure?
I want to get system hardware related information such as graphics card, cpu, no. of cpu cores, etc.I was not able to find all the info in the registry. Also where in the registry can i find info related to various drivers.
I have a form for which the objective is to show a field for each timezoneinfo stored in systemtimezones. Here are four segments of code, designer and form input code windows
I am using following code to get directory info. it works well if I search topleveldirectory. But when i search alldirectories, it reaches system level information and throws error. Is there any way to avoid searching system level information folder?
Imports System.IO Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
Compact framework)As I said previous I thought I would dabble in c# for my new project, and as I thought its turning out to be a nightmare I created this control in VB and now I'm porting it to c#.
In my control I have a PageListCollection (Similar to Listviews ListViewCollection)
This code is for listing all folders including subfolders. but when i run this code i m getting error "Access to Path F:System Volume Information is Denied" How can i ignore this folder and continue scan.? is ther any solution for this error?
I've been reading a lot of articles here and there, really, for the past two days, searching for a good local storage system. I have no immediate use for now, so I am just exploring my choices. By saying 'local storage system,' I'm talking about some sort of database used for applications that let users manage and organize personal accounts (bank accounts, web site accounts, application licenses...). I do use XML to store user settings. But if you have to manage lots of information locally, XML won't probably be good enough, I'm afraid.
So what are choices Visua Basic users? Well, as I often mention, I develop Mac software products. And I use SQLite. In fact, every one of some 40 apps sold at Mac App Store uses SQLite for good reasons. I know that you can use SQLite with Visual Studio after installing a package from sqlite.phxsoftware.com. But I don't know if your application can reproduce a database file when necessary. That being said, I'm looking for a system that I can use to create a file programmatically especially when the user launches it for the first time. So what do you use to locally manage large information? SQL Express? SQLite? XML?
1. I need to pull some data from a text file separated by a space and put it in a drop down, the first value is supposed to be the text and the second value (separated by a space) is the value of the selection. I think I need to use an array and a System.Net.WebClient. How do I approach this?
2. I want to display some data from a text file into a gridview, so using datagridview, but I want them to be able to enable and disable a checkbox in these rows (using a listview?)
This project is based on a MUD, or at least originates from playing them. I have an ascii map where each character represents a type of terrain. I have found code for reading one line at a time, but I need to not only dictate which line to be read, but how many characters in to the line to read. Basically trying to make a grid/coordinate system, where I can tell it my location is 4, 7 and the program will read the fourth line, seventh character.
I have created a working report, included a sub-report that is linked to another RDLC file in the same project.The sub report fails to load with : Data retrieval failed for the subreport, 'Subreport1', located at: WML_WS.MediaCur.rdlc. Please check the log files for more information.My question is, where are the 'log files'.I have the following code:
ublic Class frmProofSheet Public Property Caption() As String Public Property BookingNo() As String[code]....
I am trying to retrieve mails from my mail account which is working, but I'm facing two problems
1. Text mail (No-attachments) appear correctly but they include some characters like "=20" , I don't Know if there problem is in the Encoding.
2. Mails With attachments appear in a very strange format, So I don't know if there's anyway to get the attachment itself Function to Retrieve Message:
HTML Function GetMessage(ByVal msgindex As Integer) As String Dim tmpString As String Dim Data As String
I have been doing some research to determine an efficient and secure way to pass a document located on another server in the network to our web server and then on to the intranet user that requested it. While I have found plenty of ways to do this, I am not that experienced with this scenario as I have always just served documents stored locally on the web server and located nowhere else.
Our document server is shared in the domain and everyone has access to it and depending on their permissions, can access many files. I was thinking that I could possibly grab a file if I could pass the intranet users credentials but I don't know where to look to do that.
I was also thinking that maybe a webservice could do what I need but that just doesn't seem right to me because I am kinda guessing that there is already a .net library available that already handles something like this but am unsure as to what it is.
OK, so I've been trying to look into a webservice.I'm not really sure what is going on with them.I haven't been able to find anything that really explains what the purpose and reason for them are. I suppose maybe that is because they can serve many purposes?
I know there are tools available to rectify this, but somehow i cannot make out the mistake(s) that disallowed the retrieval of records, despite 2 hours of trying and referencing.
First off I am fairly new to VB .net however I have had some success in my project so far. I am creating a simple envelope accounting program for personal use. So far I have some basic forms created and have my class defined and a few methods for calculating my balances as well as changing the property data I want to work with. I now want to take this property data and save it to an xml file that I can easily retrieve the data into another form and save for later.
Here is a screen shot of the form used to gather the property data for my class
Here's the class code:
Public Class EnvelopeSystem #Region "Identification" Private eUsername As String = "" Public Property Username() As String
[CODE]...
I am looking for advice on how to get this to xml the most efficient way possible. Also if there are any blatant errors or easier ways to code what I already have I am still very new at this and would be glad to see easier more efficient ways of coding.
I am using vb.net and sql server 2005 as backend. I have a search form in which a field called billno is searched and all details are displayed in datagridview but the problem is I have to restart the project every now and then. Whenever any entry is done in database the immediate form opens is the search form so it must display the data which was inserted immediately without restarting the project.
For inserting data I am using the following code: if TextBox1.Text = "" Or TextBox2.Text = "" Or TextBox3.Text = "" Or TextBox7.Text = "" Or TextBox11.Text = "" Or TextBox12.Text = "" Or TextBox13.Text = "" Or DateTimePicker1.Text = "" Then ErrorProvider1.SetError(TextBox1, "Enter Proper Details") ErrorProvider2.SetError(TextBox2, "Enter Proper Details") [Code] .....
Second problem is have a print form in a particular format but the data retrieval in textboxes is not happening actally i dont know what to do. What would be the code for data retrieval from database into their respective textboxes?
I have been requested to implement a login form into a friend's Visual Basic .NET application. He specifically requested that I should do this using LINQ to compare the input to a table in an Access database. I don't really know why he imposed these restrictions, but who am I to judge? However, the problem is I am not overly familiar with VB .NET, or LINQ.
