Forms :: What User Enters Into A Textbox And Searches Through Data

Apr 1, 2011

so my program takes what the user enters into a textbox and searches through the data i have stored and if it matchs one of the peices of data it displays the apropriate data to the user. This all worked fine till i changed the textboxes to be added dynamicly to the form when it is load and i put all textboxes in a collection. So now when the text is sent to the search sub it sends the data over but always returns that it didnt find a match. But if i go into the search sub and just tell it what to search for automaticly it finds it no problem.

.net - Custom DataTable Searches?

Apr 14, 2009

EDIT: Note. I should have mentioned I'm not interested in using the .Select, DataRowView, RowFind, I wrote a function to search a datatable for terms in an array. I then return the datatable as a dataset so it can be bound to a DataGridView. Does anyone have any optimization ideas? Since this is a real-time search (every term typed instantly searches) I'd like to make the function as fast as possible. The speed is actually pretty good already but I figured I'd be worth asking you all if there was anything else I could change about it.

Searches By No Primary Key Fields?

Apr 23, 2009

ive been reading this forums and it already helped me a lot with my application, im new to visual studio and im currently developing an aplication for my school project in vs 2008.Im using a simple access database with only 2 tables and I creadted a form with a datagrid to show all data inside the tables, and now i want to create search buttons for each field of the table . like, "seach by Name", Seach by date" etc... i tried to use the simple code

Code:

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim cod As String
cod = InputBox("Type the Id to search: ", "Search By ID")
If cod <> " " Then

[code].....

My biggest problem now is that this code works very well to search by id (which is my table primary key), but now i want to search by other fields and this code only allows to search by primary key! Is there any way to use something similar to this code to search by other fields?

Restricted Textbox Code (Specifically, Building A Class Library With Code)?

Jan 2, 2012

I recently found this code (provided for third party use on another VB site), however,ll of my attempts to insert it into a class library have failed.I open a new class library and past the code in, and immediately get several errors pertaining to how certain objects can't be found. I find it it is crucial to use this code, unless someone can suggest to me another example of existing code that will do the same thing: make a restricted textbox who imputs can be restricted, that can handle pasting, shortcuts, text property setting, and script-entered text.

Option Strict On
Imports System.ComponentModel

Asp.net - User Enters Code Into TextBox, Code Gets Added To URL (using Session)?

Sep 1, 2011

I'm using ASP.net 4.0 VB,I am using a session variable to add a user entered code into the url of each page. I can get the code to show up at the end of the page's URL that my textbox is on, but what do I add to every page to make sure that the session stays at the end of every URL that person visits during their session? This is the code from the page that the user enters their user code.

Protected Sub IBTextBoxButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles IBTextBoxButton.Click
Session("IB") = IBTextBox.Text
Dim IB As String = Session("IB")
End Sub

This is what I have in the page load of one of the other pages. What else do I add to make sure that variable is added to the URL of that page?

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim IB As String

Bring Up Characters Through Named Searches?

Jan 17, 2011

I am very new to VB.net and for a project I am supposed to do some "outside research" and create a database. The database should consist of items (sports players) who have a number of different values (one set is physical: strength, speed, agility, acceleration) and preferably another (technical ability: ball skill, dribbling, shooting, etc). I want the database to classify these and give each traits such as "Power Shooter" if the shooting stat is upwards of 90, etc. I want to be able to bring up characters through this and also through named searches.

Creating A Search Control Where Searches Can Be Compounded?

Aug 25, 2009

I'm creating a search control where searches can be compounded. So, for instance, I could create a search for Orders where OrderID = 1232 or OrderID = 2343 and OrderID <> 23435

So I have a button that users can click to compound. Obviously its a complicated problem to do well, but in any case, on my path to trying to find the best way to do it, I wanted to create a variable that could be either '=' or '<>' depending on the value of some other variable set elsewhere.Is there a way to do that? Or do I have to switch to Expressions?

VS 2010 Assit With Sequential Searches And Arrays?

Dec 8, 2011

I'm new to VB and my book doesn't explain sequential searches very well. I need help with the application I'm creating for school. My application has to allow the user to enter a number and then it will verify if the number is valid by searching through the list of arrays I provided.The question:Create an application that allows the user to enter a charge account number. The application should determine whether the number is valid by comparing it to the numbers in the following list: (see code)The list of numbers should be stored in an array. A sequential search should be used to locate the number entered by the user. If the user enters a number that is in the array, the program should display a message indicating the number is valid. If the user enters a number that is not in the array , the program should display a message indicating the number is invalid.

Creating A Class That Searches A Binary File For A Specific Customer Number

Jan 4, 2012

I am creating a class that searches a binary file for a specific customer number. I am using a binary search that keeps on slicing the file in half until I find the customer number while is sorted. Once it finds it I am positioning it at the first instance of that Customer number as there can be multiple records with the same Cus Number.

Now here is my question. I now need to loop through this Customers records and do some data base searches. Since I want to make my class as generic as possible what should I pass back to the calling class? An Array with all their records. If I do this I have to loop twice, once in the class and once when it passes the array bac to the original calling class?

Forms - Binary File Read Operation - Make Searches Fast Without Freezing The UI

Feb 9, 2011

I have a windows form which to summarize lets the user open a file containing 32 bit hashes, then search for one of them. The hash is then converted to its string representation. The application is giving the results I would expect but I'd like to make it execute faster than it does now; some files can be pretty big > 100 MB.

I'm doing the file read using a BackgroundWorker object to display progress updates and ensure that the UI is available during the process. But for that i need to add a System.Threading.Sleep(1) instruction in the loop; otherwise the application freezes with big files. And System.Threading.Sleep(1) creates a noticeable lag. Any suggestions on how to make searches fast without freezing the UI? Getting speeds comparable to hex editor programs for example.
