I'm trying to build a search tool for my application... I have a form with a bunch of criteria which the user may or may not fill in. The tool is looking up against one table in the database (OLEDB) so I wanted to pull in all the data from the table into a dataset (when the form loads) and perform the search on it. I'm not sure how to search through datasets... this is the code I have now:
Public Class TxnLookup
Dim daLookup As OleDbDataAdapter
Dim dsLookup As DataSet
Dim cbLookup As OleDbCommandBuilder
[code]....
but I get an error on the foundrows = line ("Value of type 1-dimensional array of system.data.datarow cannot be converted to system.data.datarow").... is there a better way for me to search the dataset?
I'm in a bit of a quandry. I am trying to build a simple search form where the user selects the column title and in puts the criteria then clicks the search button. This is the code I am using
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click details = ComboBox2.Text 'column name selected by user specifics = TextBox1.Text 'criteria input by user
Is there any free tool available that can be used to build Active Directry query also can i execute active directry query through c# code because while connecting to active directory through object model and iterating through each property of the active directory specially when all the property is not requierd the performance cost is comming. What I want is to query Active Directory domain get some property value ans save it in the sharepoint list, I am using object model to do this but at the cost of the performance. I am thinking to execute the query through C# code same as any Active Diretory Query tool to pull the value and then save it into the list.

Is it possible to build a search engine to use on a DVD that contains Word documents, text documents, etc.? Say I wanted to find all documents with the name "James" in them. In the search box I would type "James", and it would return the results of everywhere James is found. Or suppose I wanted to find all Land Deeds where James is found, is that possible? All search engine examples that I have seen on VB Help has to do with databases, and I guess to an extent, my DVD would be the database.
i've searched high and low and cannot seem to find how to implement an application tool bar in VB.Net. I want to basically create a scrolling text banner, which docks itself on the top of the screen on which scrolls along a message. Pretty simple in VB6 but can find a VB.net alternative.
We would like to know if there are any recommended tools in .NET that can scan through a VB .NET project & do an analysis.It should report on the Lines Of Code, provide no. of Routines, No. of 3rd party Tools, No. of Variables, Forms Diagrams, No. of Classes etc.
I was just wondering - is it possible to detect, with either .net, SilverLight, Flash or some other plugin, whether or not Snipping Tool is open, or detect when the user opens it (after the page has loaded)? Also is it possible to detect when print screen is pressed even if another window is active?
i need to convert a Java tool into a VB (2005) application. Most things are fairly straight forward, but i have on a few lines my problem the appropriate VB function to find.
my name's Sardor, from Uzbekistan. I have some experience in coding in vb.net, but i am having real difficulties with realizing one project. The thing is to code a simple drawing tool and embed it to an existing vb.net application. The drawing tool should be a simple object and have the functionality very similar to mspaint (windows built-in drawing software). It should also have some custom brushes, and it should support loading and saving pictures in common formats such as bmp, jpeg, gif, and png. how to code such a drawing tool? Or can I instead download any such control or tool as an add-in to vb.net and use it?
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.

Im trying to build my first N-Tier web application. And it seems like im doing it wrong. Ive been kinda working out of this book, but to me it doesnt seem like the right way to do this. In the book the guy builds User and Data centric objects but everywhere I see ntier everyone is always talking about BLL and DAL ive seen nothign on UC and DC objects.Right now I have Interfaces and serializable structures, user and data centric objects. The data centric object does all the validation and connecting to the db, as well as returns any violated rules, but when I once i started pulling it all together it just doesnt seem right.Ive already wrote a ____ load of code and now am kinda stuck. I dont know if i am doing this right and dont want to continue writing any code if this is all messed up.Ive been reading as much as humanly possible and im still just a little confused. I mean I understand the concepts of seperating the logic into different layers and tiers and all that but as far as my implementation of that I just feel somethings a bit off.
I've compiled my application and started testing it on other machines.
It crashes instantly on every machine except the build machine - I'm fairly new to programing so any pointers as to where I would start would be great.
If I install VS2008 on the test machines it runs fine...
i currently have a project. The application created in this project will be located in a server, and some machines can access this application at the same time. The problem is, i don't know what's needed to connect that application to several machines. I know how to build this application and run it in a single machine, but i have no idea about running this on server.
I'm a Quite new to Visual Basic 2008. I have to build a database application for one of my assignments and one of the problems I'm having is to build a form that will be used to search a customer from a Customers table. The database is from access2007.
I have to have 4 radio buttons on the form which will be the options to search the customer by, so I can search by Customer ID, Customer Name, City and postcode. When I select one of those options I need to enter the phrase I'm looking for within a text box I have called TextBoxSearch then press a command button to perform that search but I'm not sure how to do this.
The customer ID is the 1st row, Customer name is the 3rd row, City is the 4th row and the postcode is the 5th row. How do i tell the program to go to that row and grab the detials based on the text entered from the text box? and display only those detials on the datagrid view?
