Store Paragraphs Of Information, And Then Search For It Based On A Keyword?
Oct 13, 2010
I want to build an application using VB, that is essentially an information system.The operation of this system would be as follows:1. User can select one of several buttons, each button being a different topic.2. When a button is selected, information about that topic appears on the right hand side of the form.3. The system allows information to be added by a user So, for example, if a user clicked on the button named 'Banana', information about the banana would appear on the form, where the user could read this info, scroll down etc.I would also like the user to be able to search a specific word like 'apple' and for information on the apple to appear.How could I implement this? I don't know how I would store paragraphs of information, and then search for it based on a keyword.
i m working on a project on vb.net with access database...and i need a code for separating the information from my complete package by following some kind of search,
1. for example if we type a word "publish" in a textbox and then click on a button...then it should display all the rows and columns containing the word "publish" in the grid view.
2.i also need a code for selecting the information from a particular column based on the key(or keyword) provided by the user
I m trying to create a software in vb.net for some genealogists to trace their ancestors History, the users will search for the document in 3 ways
1. reference number from a combo box. 2. By the title of the document. 3. by inserting a keyword from the documents abstract..
i have already loaded the picture. i hav put all in one note pad my reference no., on next line i put my abstract and on the third line i put my path where the document is located.in coding i put all in different array.... making the program read all one by one line wise.i want to make search thru the keyword... means wen user inserts a key word in the textbox the program read all my abstract and then in a drop down it should display the documents that match the keyword.
Attached is a visual representation of My Array that was used in my VB6 program the dimensions are:
CODE:
I am using an ACCESS DataBase to populate the array.
Using the For Next Loop I can access any position within the array such as a individual cell or group of cells. Also using the Step Keyword of the For next loop I can select a group of cells to manipulate based on the Step factor. This worked well for me in VB 6. I am now migrating to vb 2010 and cannot fine documentation as to how this would be done on zero based arrays in Vb 2010.
In VB 2010 I see no reference to the Step Keyword nor examples of how it would be used with zero based Arrays.
A example of my use of the step keyword is:
CODE:
Any of the above loop setups works for me using VB6 Any Documentation or code would be use in my vb6 to vb2010 migration?
I am wondering, would it be easy to make a program to:1. Activate Window2. Search for a sentence on the webpage.3. Search for a keyword in the sentence.4. Execute action based off the keyword.5. Repeat every 17 minutes.Is it possible?I have used AHK, but I like the interface of VB better. Any insight?Also, I created a whole browser aspect through Visual Basic. Or would this be easier to just run through a program instead of my own created web browser?
I am trying to search one column (Titles) of an Access database using an SQL query. The search entry comes from a split string passed to an array and inserted into the SQL command. This works well, however, the results I get back are for entries containing EITHER of the keywords entered, not entries containing ALL keywords entered.
The code I am using is::::
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click dgvSearch.Visible = True
[Code]....
The loop is working, but acting as a new search as opposed to searching the results of the previous search.
i need to search any text in my entire database and get the result in my dataset. my database is in ms-access. i have written the following function for the same:
Dim con As OleDbConnection Dim ada As OleDbDataAdapter Dim ds As DataSet
[Code].....
the query written herein works fine if you copy and run it in access so i guess it is correct.
I want to search a text file (*.txt extension) for a certain keyword or a part of it. And then let the found item be displayed in a listbox or something else. Now the more difficult part, how can I display the word in front of that found word ?
Example: I search for VBFORUMS in a file called test.txt I find this: VBFORUMS but in front of that is this: IDS_IDS_TXT_008912VBFORUMS
How can I then display the IDS_IDS_TXT_008912 on a label ?
I have three controls on my form; Textbox1, cboCity, lstCity When something (lets say "a") is entered in the TextBox1; I want to get each and every item in combobox cboCity that starts with "a" and add them to listbox lstCity.
I want to store some string information in my application exe. The information should not be lost in when the application is closed or restarted. It should be like editing a text file in application resources.
I am trying to store confidential encrypted user information for my program on a single computer. I do not want the application to be copied on to another computer and be usable. So I was thinking about storing the information in the Registry but I read that that is a very unsafe location and is bad for more reasons then one. I started storing the information in the programs Settings.config file but I am not sure how to encrypt that information. The only thing I have gotten to work so far is storing the information in a XML file and encrypting that which has worked but I want the information to be more hidden and more secured.
I was wondering how you can copy information (from a webpage, for example) and store it in a string?Also, how would I take only one word of the string if there are spaces between words and I will always be removing the word with the same location in the string (for example, the last word in string).
I had been doing a split function after the ":" but, that doesn't turn out so good once you add in file paths. I have turned to trying to grab the first ":" from the left using the "InStr" function which returns the char integer. I need a way to grab all the information on that line after the first ":".
I have an ASP.NET application. It resides within another ASP.NET application. I put my DLL in the other apps bin folder and have a subdirectory with my aspx files. I can't edit the main app's Web.config.
So where can I store configuration settings? For example, this is an app that will get deployed to various clients. I want to store the client name used for display in the headers and such. And the location of a logo file.
I am new to development and I am looking for some pointers. I have a sql 2000 database and a vb.net app. Right now the SQL username and password to connect to the database is stored in the VB application which is not convenient since we must change the password periodically. The user opens the app and enters the username and password for the vb application. Using the credentials stored in the application to connect to the sql server, the app checks the username and password stored in a user table in the database to determine if they are allowed to connect or not. For various reasons, it is not feasible to simply have the application username and password be the same as the database username and password. We must have only one database username and password and it must be changeable. Like I said, it is now stored in the compiled application which is inconvenient.
This is kind of hard to explain... I would like to create a listbox, that holds items, and those items store data. Ill try to explain with this picture below. The code I have now is Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
I have a fair bit of experience with VB.NET and C# (In this case I chose VB.NET, blame my laziness), but I do most of my professional work using PHP. I have no experience what so ever in using any database with VB.NET let alone MySQL.Just FYI, at the moment I am only trying to Query the database to gather the information required to activate. The Activation wizard and algorithm building (which is finished anyway), and everything else will come soon. I chose the MySQL database because I have experience with it, and it seems the best option for remote usage.The whole idea already works in PHP, I'm just have major issues moving it accross into VB.NET (Using the MySQL Connector.NET);I understand the basics, and all I need to know how to do is Count Rows and gain access to the other information in a row based on provoided information (in PHP, through mysql_ result)
So, here goes nothing, this is the Query code I am using in PHP to complete the job I want to do in VB.NET. [code] As you can see, I basically need to get the PHP code into VB.NET to fit into the 'btnQueryDB.Click' Command in VB.NET. By Equivalent, the Product ID in VB.NET will come from 'txtPID' and similar, Serial Number will come from txtSNUM. Once counted to be 1, the Activation Code and Status will be fed into 2 other text boxes in the form. (acCode, and acStatus).
While trying to find an answer to my question, I came across a project called OTSe, which allows people to make they're own online 2d online games. The system is based on an open X, Y, Z square tile map. For the sake of easy understanding, lets say they're are 3 types of tiles. Tiles you CANNOT walk on, tiles you CAN walk on, and tiles that SLOW YOU'RE CHARACTER DOWN.The project team has created a API class for users to work with in order to develop tools. What I'm trying to do, using they're classes, is GET the all the tiles on the current floor I am walking on, and then display them in a tile grid on my form, changing they're color depending on what type of tile they are. If the tile is NOT WALKABLE, make the tile gray, if the tile IS WALKABLE, make the tile brown, and if the tile SLOWS YOU DOWN, make the tile red. I also need it to store the information of each tile, since tiles are objects, and have properties.
In my application I want the user to enter information that can be stored in BOTH an SQL database and and Excel spreadsheet. I tried research but can't find the code to include or import Excel into my project.I've seen examples like:
Dim excelApp As New Excel.Application Dim excelWB As New Excel.Workbook etc....
but VB doesn't recognize it as a shared namespace. Is it possible to load a spreadsheet into a VB project with express edition?
I'm trying to make a application with a login system. I want to store user and password information, into the application. So I can access it from my administrator account. I have tried to make a textbox for every username and password,And then save it into my.settings And then I run the finished application, it works fine to store the information. but if I copy the application after I had entered some user/pass information. All textboxes I blank on the other computer.
I am looking for information on how to store information that has been entered into an application form before it is cleared for new information. I would like to store it with a date and time stamp if possible.
I need to have the ability to have a Global variable/class that stores some basic information about the currently logged in user including that user's preferences, security rights, UserID, etc. This information will be needed by any/every part of my application. In the past I have either used a Public variable/class in a vb.net module for this purpose. I'm trying to get away from my old ways of doing things and was curious what people currently do for this functionality.
I am thinking a singleton or 2 regarding preferences and security but am not sure if that is the best way to go.
EDIT: I asked this when I was too sleepy last night. This is an n-Tier WinForms application.

I am writing a VB 2008 program to display and update records from a sql database. This particular form is used to display and modify retail store information records from the database. I am running into an issue with saving the records once they have been changed.The error message I am getting is "Update requires a valid update command when passed DataRow collection with modified rows". I am including all of my code for the form because I am not sure what is relevant. I am getting the error when SaveTheEdit() is called on line 83. [code]
make a application where I can store a lot of account information in a file on my computer. This is how it works so far.I have a class called "AccountInfo" with some properties such as Account Name, Password, etc... This is bound to a DataGridView via a Bindingsource. So basicaly what I'm asking, is how can I save/load all these accounts in my computer easily in a file or something?
How can i capture my console real time output and store the information in a log file?
i know that i can write in the file when i write in the console window, there's got to be a better way... how can i capture the console's output stream?
I found that Console.OpenStandardOutput is a stream, but i can't read from it
Dim r As New StreamReader(Console.OpenStandardOutput) MsgBox(r.ReadToEnd) r.Close() r = Nothing
I'm a newbie in visual basic. I'm doing a login system. I'm done with the GUI. but for the programming part, I want to know where to store new user's information along with the username and password. I've done research. seems like it has something to do with database. p/s: I'm looking for high security in storing data to prevent hacking.
I am trying to come up with a way to store 3 pieces of information for each employee in the company on a daily basis. So for instance
Day 1: Joe, 8, 80 Day 2: Sam, 10, 90 Day 3: Bill, 5, 40 Day 4: Bob, 8, 40 Day 5: Sue, 2, 50
most of the applications that I build are Create, Read, Update and Delete type applications that don't really need arrays so I have almost no experience with either.
VB ' Dim iDays As Integer = NumberDaysPerMonth(Date.Now) Dim DayNumber(iDays) As Integer
