Create An Application That Will Allow To Type A Search Term?
Oct 11, 2009
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()
[Code].....

I set up a gridview to display search results on a webpage.
I have the code below that is "supposed" to replace any instance of a search term, with a bolded version of that word.
I've tried many different versions, but nothing is working.
Private Sub gvSearchResults_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gvSearchResults.RowDataBound

I have a textbox with button wired up to a queryextender. My goal is that someone might enter into the textbox a name (e.g. "Dave Mackey") and receive back all relevant results. The problem is that this information is spread across two columns in the underlying database (e.g. FIRST_NAME, LAST_NAME). My code looks like this:
<asp:QueryExtender ID="QueryExtender1" runat="server" TargetControlID="EntityDataSource1" >
<asp:SearchExpression DataFields="first_name,last_name" SearchType="Contains">
[Code]....
If I enter "Mackey" it returns results, but "Dave Mackey" returns no results, I'm assuming b/c it is looking for the entire value in one first (either, but not both together), whereas I want it to return any rows where it finds the entirety even if it is spread across multiple DataFields.

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 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 a simple application which can create/update/delete/search records using Access database. If i add a record, save it, then close the application and run it again and search for that record, it appears. However, when i write some code to my application, nothing to do with the search function, and i run the application the record is not found. For example i added a button to clear the textfields, and when i ran the application the records i have added earlier were not found.

Can anyone help me to break down the instructions for this assignment.Create an application that allows the user to type in a 32 bit number using the binary system, and convert that number into the decimal numbering system.For example, the user types 000000000000 0010 (where there are 30 leading 0's, 1 then 0 from left to right), and the output would be 2.The user will type a string that is 32 characters in length.A For loop 'reads' each character using the x.substring(i,1) where i is the current character we are reading and 1 means one character only,and x is the entry the user typed (use a Textbox to get the entry but Inputbox is also ok).When you start at the first character (from the right) then that value is to be * 2 ^ 0 then the second character is to be * 2 ^ 1, then the third character is * 2 ^ 2, hence:( x.substring(i,1) converted to Integer ) * 2 ^ j represents the decimal value of the current number (0 or 1) we are reading.A variable is needed to accumulate all those values.After the loop is done, display the accumulated value.To test this code on a simple version, enter a 4 digit binary number, where 0010 is decimal 2, 0110 is decimal 6, 0111 is 7, and 1000 is 8.
My understanding is the user must enter 32 digits into a textbox. The textbox should place limitations that only allow the digits "0" and "1". This error could be displayed to the user with a messagebox that then asks to reset the value orginally inputted into the textbox. My understanding is I should continue creating the formula of the position of each character where the third character is *2^2, fourth is *2^3, fifth is *2^4 and so on? I don't understand the formula and how it works.

I'm wondering if it's possible to create a listener type application that would monitor webaddresses that the user attempts to go to. And can then either block or redirect the browser to another website. Purpose: I know this seems to sound a little weird but what I'm attempting to do is a NetNanny type application that can run on the user's PC and the allow, prevent, rewrite (would look for particular keywords and rewrite them "words I wouldn't want my 7yr old seeing or reading), or redirect to other webpages. I would also like to be able to handle both IE and Firefox browser with this one application.

My search application isn't working. When the "Search" window pops up, the label stays frozen on "C:". The application isn't freezing, just the search. Why? I can still use the buttons on it, and everything else seems to work fine.

I'm having a problem with converting from one source type to a destination type. I have a form with 2 buttons (button 2 uses the OpenFileDialog to have the user open an excel file set to NewFile),(button 1 takes the contents from specific cells in NewFile and arranges them how I need into oXLApp1).

Is there a way to get the IntelliSense for a lack of better term to work like it does for C#? For example, lets say I want to add a MessageBox to my form. With C# as soon as I get around Mess it's already coming up with the rest of the word, and the same with variables and control names. Just wondering if I'm missing a setting or something some place or if this is just another example of how things are different between the enviroments. Using Visual Studio 2005.

I'm attempting to dynamically register entities and configurations with a context (ef4 code-only). I would normally do:
Private Shared Sub ConfigureDatabase(ByRef Builder As ContextBuilder(Of ContextExtension))
'Load configurations for each of the tables (Entity sets) in our database...
ConfigureEntity(Builder, New ContactConfig)
End Sub
Private Shared Sub ConfigureEntity(Of T)(ByRef Builder As ContextBuilder(Of ContextExtension), ByVal config As EntityConfiguration(Of T), ByVal setName As String)
'Register the entity configuration with the builder
Builder.Configurations.Add(config)
'Register the entity set name with the builder
Builder.RegisterSet(Of T)(setName)
End Sub
Where ContactConfig is a class which inherits EntityConfiguration(Of Contact) and Contact is a class which implements an interface IEntity (IEntity is common to all entities). So... I need to search a namespace (say Project.DB.Client) for all signatures that match:
EntityConfiguration(Of <Class which implements IEntity>)
How can I achieve this?
