Create A Search Textbox That Will Bring Up Titles As Type Them?
Feb 24, 2009
I'm trying to create a search textbox that will bring up titles as I type them. For instance, when I start typing D..all titles that begin with "D" will appear in drop down menu. I found a code that I believe does this but I'm getting error messages. The error message I am getting is: "cmbMovies not declared" and "CONN_STRING not declared". I created a DataSource named cmbMovies and it did not solve the problem. Am I looking at this correctly? Here is the

I'm trying to create an application that will allow me to type a search term, corresponding to any field contained in a database, and have the results displayed in a datagrid view. The idea is that the application will display any records that have the search term in any of the fields, rather than just allowing the user to search based on one field only.
I keep getting an error on the dataAdapter.Fill(dt) line. I've tried reorganising lines of code just in case my logic was wrong, but the result is the same. The program just crashes when it reaches this line.
My code is:
Public Class Form1
Private Sub AuthorsBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AuthorsBindingNavigatorSaveItem.Click
Me.Validate()

i am using VB2008 and i need to work out how to search a database. it probably will be very easy but i cant understand it and havent been able to find any tutorials that are for VB 2008, only for other things that wont work, mainly because i dont understand much of what is been written/said/coded.
But the search button (btnsearch) isnt doing anything when the code is tested.

I'm trying to create my own type of spider/search engine thing for fun. I start with a URL, then grab the HTML ...from that I have a REGEX that is supposed to pull out all the links. I figured I would randomly pick one of those and keep going as I save the HTML to my database.[URL]...You can see that I get some real URLS and sometimes I get back some that are not. NOW I return these to a RichTextBox and on the REAL URLs, these get formatted in blue and make a HAND icon when you float over them. This makes me believe that something SOMEWHERE knows that these are good url's. That would be a good thing to tap into so that I could get rid of everything in that box that is not a real URL.

I have to make a basic program that: Create a program with a simple interface that
1. Asks the user type his/her email address into a textbox.
2. When the user clicks the "Evaluate Email Address" button, one of two message boxes pops up: "That is a valid email address!" with an "Information" icon, or "That is an invalid email address!" and on a second line, "Please retype your email address.", with an "Exclamation" icon
3. To be considered valid, the email address must -include an "@" symbol, and -it must end in either ".com", ".net", or ".org" or ".edu" (I don't know how to check a string and test if its last four characters end with any of these and make it say not valid email address. I think I might have to use a case statement)

I have a dataset containing 2 tables,Customers and Contacts. Just showing the master-detail is not a problem. Problem occurs when I try to search the master table to bring in the detail table. Searching the master table shows only the master record, but not the related detail records. Adding a 'findby' query on the detail table only shows the records.url.. Normally when the master table is filled, the detail record shows in a form.

I have a VB.NET desktop application that I'm using to monitor events in another windows application running on my system.I need to respond to certain events in a matter of seconds.One of the events I'm monitoring instantly changes the window title of a child window within the main process (I'm not changing it, the application I'm monitoring causes the change in it's own child window title).I have a function that uses windows API's to iterate through the title text of all the process's child windows, and I'm checking for certain values in the titles.Is it a bad idea to be running this timer/title check once every second? Are there performance issues associated with running a timer in windows every second 24/7? Is it also bad for performance to be calling the API's which retrieve the titles of all the application's child windows? Could I eventually cause that application to crash by sending requests to it so often?

Wish you all are doing fine at the start of a new year
I am a beginner developer. I am developing a website. I have few divs which made up dragable boxes enhanced by jquery portlets. see the codes below.(html).
<div class="portlet">
<div class="portlet-header"> Category A </div>
<div class="portlet-content">
[Code]....
I also have a stored procedure from the database developer that return the list of categories. Depending on the user selection, the list of categories can vary.
So i have to dynamically create those Boxes. Each categories returned by the SP should replace Category A, Category B, and so on. As i can't know the number of categories returned by the SP i just hard coded those divs. My question is simply how ? How can i achieve this?
I have to be using VB.net in VS 2010. The database is in SQL server 2008.
