I have an object that I'm instantiating in VB.NET. I'm trying to see if it's storing a particular value somewhere in it. If I look at the object in the watch window in the VS 2010 IDE, I see this huge tree structure with thousands of nodes, many layers deep.
I'd like to be able to search for a value "1234" in this huge tree structure. I tried using serialization to convert the object to xml, but it complains that it doesn't have a parameterless constructor, since this object is provided by a third party, I can't add a parameterless constructor.Is there any way that I can search this object? Is there anyway that I can convert the tree structure that I see in the vs 2010 watch window to an xml document, or a string?
I tryed searching for an user in active directory using the code below but it gives me the error in the title of this post above:
AD = New DirectoryEntry("LDAP://OU=SchoolOUhere,OU=Staff,DC=garrard,DC=ketsds,DC=net", "", "", AuthenticationTypes.Secure) AD2 = New DirectoryEntry("LDAP://OU=_Groups,OU=Staff,DC=garrard,DC=ketsds,DC=net", "", "", AuthenticationTypes.Secure)

I'm trying to search an object array for a particular object and return the index. g always ends up being -1 even though I'm expecting it to be 0. What am I missing?
Private Sub btnX1_Click(sender As System.Object, e As System.EventArgs) Handles btnX1.Click Dim g As SByte = Array.IndexOf(buttons, sender) MsgBox("If worked: " & g, MsgBoxStyle.OkOnly, "Test") End Sub dim buttons() as object = {btnX1, btnX2, btnX3}
Basically, I'm trying to design a function that can get the index of an element from one object array and use that to grab an element from a different array at that same index.
I am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj Inherits baseObj Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?

Im having a bit of trouble with my form,I have a QUOTATIONS form that displays data to the Employye about Over timne etc. I want to be able to Search through the Employye file using either the ID or there Name.
I have the code to search through the file using there ID, i have addapted the code for there name, but can't run both at the same time.As in - i can serach by one, but not by both. If you see what i mean?
I want to be able to search by Either ID or Name. I can run either one or tother, but not both at the same time,giving them a choice.Was thinking about using a seperate form, but that didn't work?
I am trying to search through items in listview control in vb.net one by one. i.e When the user types in some keyworrk in the textbox and presses enter, the first found item in the listview should get highlighted, when he presses enter again, the second search item in the listview should get highlighted and so on.
I am not fully aware of how to keep track of already found items while searching. As of now , I am searching all the items in the listbx using the code :
is there anyway i can search for a particular row in all columns in a database and display them accordingly? like in a customer table, i have CustomerID, Name, Address is it possible to search for all the details of a customer?
I am doing an assignment for class and it is searching an SQL Database file. On the GUI I have a text box and a button to search this database. It is presented on the form in DataGridView connecting to the file, and the file connection test succeeded, I am kinda so so on understanding what is going on with the connection between the file and VB 2008 but I am getting 4 errors: Warning1The designer cannot process the code at line 119: Me.PlayersBindingSource.DataSource = Me.BaseballDataSet
I am pulling the computer model from the bios, the passing the result into some SQL to find it in a table (as the bios name, and the names in the database are different).If it exist, it writes the value from the database to a combo box (cbModelBios)I am trying to debug the case where the computer model does not exist in the table.I figured I would just try to see if the SQL statement returned null, but I am still getting an error [code]
example:ccleaner , malwarebytes, spybot ETC the list goes on.He has a notice in his app that says a user must install all to the default program files DIR.So if it is not installed there obviously it cannot run the application.Now after atma lesson he gave me on hardcoding directorys i told my friend he should not limit a user to where they should install the application.

I need to create code that search for numbers in a name. I have 50 Labels on my form named Ing1 to Ing50, the code I am looking for must search and locate then number only and then return the number As Integer to be used in another code block. Is this possible?
Im trying to input a search box in my forms so that when I type in a customers name it will show there record. I've managed to do it in my transaction form, but not in any other standard forms. In my transaction form I've got this code:
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtSearchSalesID.KeyPress Dim dv As DataView = New DataView()
I am learning about the search capability in an array. I wrote a code that stores three names (first & last) and I want to:
- Make the user select a number (from 1-3) by using a (combobox) - If the user select the proper number then a message will appear that the name is there. - If not then an error message will appear.
I did all I could by creating this but my main problem is in the (ButtonFind). I went through lots of tutorials and this is what I came up with and I hope that my code is correct.[code]
I have 5 strings of varying length and I want to see if any of them have a 1-character substring that is not in any of the others. If it does then I want the value of the original substring to become the value of the string holding it. The names of the five strings are T1, T2, T3, T4, and T5. [Code]
I have a problem when searching an XML string. The problem is that I can't get it to work. I have a big XML in a string, and I only need 2 values that are each in seperate elements. It is hard to explain so it's best I just show it.This is my XML: (sorry it's very long, but I want it to be complete so my question can be answered properly).
For each <transaction> I need the value of <Number> that is in <Header> and the value of <invoicenumber> in <line (id=1)> ... I have colored the elements in my sentence the same as I colored them in my big XML?The number of <transaction>'s can vary for each XML (these are a webservice response).I've been looking for 2 days now, and I can't seem to grasp this XML stuff unfortunately.
I have datagrid, a textbox and a button .. the user puts a value in the textbox, and when he presses the button it should search through the datagrid for that value, if found, 1 of 2 things may happen:Or the datagrid only shows that value Or the value the user put in the textbox show indexed, like, with the blue thing over?
I am trying to perform a search and this is as far as I got. I am trying to search through a datagrid for a match either by last name or ID. I know the ID search is almost working but not sure how to make it look for whats in the text box... how to match the value in the search text to the datagrid.
Private Sub SearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SearchButton.Click Dim ind As String = 0 ' Dim Result As String Dim SearchArgument As String
I have a datagridview with three columns (ID, Name, Address). It's bound to a database that contains around 500 items.I want to be able to search the gridview for data given in a text box, and then highlight it.If possible, pressing the Next button should find the next match, and the Reset button should clear all selections (nothing highlighted)
On my form there is a datagridview that may get upwards to about 70k items depending on how scan happy our customers get. I also have a textbox which allows the user to search the datagridview using the textchanged event. I'm using a select statement with the like clause and filling the dataset. I dont think this will cut it, because the program hangs and gets laggy when there is a large amount of records. Whats the best way I can do this if performance is a top priority?
I'm writing a program for my friend as a gift. He's a movie lover, and has this Excel spreadsheet with all the movies he's watched in it. I converted the spreadsheet to an Access database,then used that database in my program. I've been going by the example in my textbook (Programming with Microsoft Visual Basic by Diane Zak), and everything been working until I put in a "Find Movie Title" button. I want to be able to search the column "Movie Title" for a title input by the user (whether it's the whole title or just a few characters)Here's the code:
Private Sub btnFindTitle_Click(ByVal sender As Object,[code].....
