I am slowly getting used to VB coding using VB 2010 Express. I am trying to develop a WinForms application to access AD and get a list of computers in a particular OU. Is there any short reading material that will educate me on how to interact with AD from VB code? I have added "Imports System.DirectoryServices" and "Imports System.Net" headers to my code but don't know which functions/api to use.

The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.
I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this. And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working?
Private Sub txtDestPayRate1_KeyDown1(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtDestPayRate1.KeyDown
If e.KeyCode = Keys.Enter Then

I am designing a backup/restore utility for work.atm i have been able to populate field for PC name, IP address, MAC address, number of printers installed on the PC but i am wondering is it possble to get all the printer information 'with the click of a button' to print all information like the prnmngr.vbs script down.I am able to run a batch file but i wanna get it to go from that app or even embed to batch file to the app and run it form there .
View 4 RepliesI am using VB2005 and trying to put an application together.What it needs to do is retrieve information from a binary file, possibly alter that information, and put it back into a new file.The file is a .wav file with data appened to the end. There is an additional section at the end of the .wav file which stores xml data.I have found that if I open this in a hex editor and make a 1:1 swap on any of the bytes that the application that the file is for can still read the XML.If I tried to add or remove characters from the XML then it would not read. I located a header byte and incremented it to resolve this.
This worked as an excellent bandage to do conversions where the data always needed to be changed to the same thing.What I have been asked to do is build logic that allows for different things to happen depending upon what data is contained within the file.The method that I am currently trying to impliment is:
Read through the file with a system.io.binaryreader
Searche for a bytestream that will signal data is coming
For example:
If System.IO.File.Exists("C: est estread.wav") Then
Dim findit() As Integer = New Integer() {&H3C, &H55, &H73, &H72, &H44, &H65, &H66, &H30, &H31, &H30}
Dim i As Integer[code].....
And then extract all the data till the end of element marker "<" It seemed like there should be a better way and I was looking for some insight. If I proceed with this method, I will have to read the file one time to gather the information and then a second time to write it all out with the header modified for length.This is my first experiene with working with binary files in this way.Also,I've been experiementing with building a string and slapping it back in at the end using the binarywriter.write(string) method.I noticed that it was putting in header characters before the string.These seem to change if I change the length of the string.At one point it was d0 07. Later it became e7 07. Does anyone know of a way to prevent this header from being inserted?
I tried a for each loop to grab all of the characters from the string, convert them to a byte array and deposit the byte array into the file, but the header remained the same. When I write the byte array generated from a system.io.binaryreader I do not get this header.
I have a fair bit of experience with VB.NET and C# (In this case I chose VB.NET, blame my laziness), but I do most of my professional work using PHP. I have no experience what so ever in using any database with VB.NET let alone MySQL.Just FYI, at the moment I am only trying to Query the database to gather the information required to activate. The Activation wizard and algorithm building (which is finished anyway), and everything else will come soon. I chose the MySQL database because I have experience with it, and it seems the best option for remote usage.The whole idea already works in PHP, I'm just have major issues moving it accross into VB.NET (Using the MySQL Connector.NET);I understand the basics, and all I need to know how to do is Count Rows and gain access to the other information in a row based on provoided information (in PHP, through mysql_ result)
So, here goes nothing, this is the Query code I am using in PHP to complete the job I want to do in VB.NET. [code] As you can see, I basically need to get the PHP code into VB.NET to fit into the 'btnQueryDB.Click' Command in VB.NET. By Equivalent, the Product ID in VB.NET will come from 'txtPID' and similar, Serial Number will come from txtSNUM. Once counted to be 1, the Activation Code and Status will be fed into 2 other text boxes in the form. (acCode, and acStatus).
Quick question, im making a simple application that will store all my passwords and logins for different accounts i have i.e hotmail, facebook etc the way i found is working but surely there is a much simpler way to do this, because at the moment im calling a select statement passing in a parameter and getting a result back which is fine, but the way im getting the information out of the DS doesnt look right, in that way i mean i have seen it done simpler ways then what im using and unfortunatly i cant find the tutorial i was looking at but this is my code.
Dim Login As String = dss.Tables(0).Rows(0).Item(0)Dim Password As String = dss.Tables(0).Rows(0).Item(1)Again there is another way of naming the coloums you want im sure, because if i was to change the SQL table later on then that change will effect this application.
So what i would like to know is how can i name a coloum i want to use, the SQL table consists of 3 coloumns 1. UserAccount 2. Password 3.Date Created.
Well I am currently trying to get the word/text in between these 2 things

how do you add information from another datasource into a cell in a data grid which has the relevant information i.e order_bindingsource grid which has the information order id, item id, quantity and cost per item.
The item id I have linked to the Productbindingsource but I also need the information to be shown cost per item which is in data source products.The item id is a drop down box with the items displayed what I need is when an item is selected I need the price to show up in the cost per item box.
I have two split-arrays and two columns (first name and last name). How can I add my two split-arrays to my datagridview?My code does not work, because all last name entries are at first name.

For i = 0 To UBound(array2)
datagradview.Rows.Add(array2(i))
Next (i)
Next (k)

I have a few questions regarding getting information from other programs.
For instance, once i launch a console application i want my other program to read it's output. If my build.exe reads whats printed in cmd.exe and then outputs it live on a textbox <--- How do i do that?/Is it possible? Im sure it is. And then i want to know how much % of CPU is used by the program and how much memory are used.
I made up Form where you need to fill in information like Name, Surename and Group. And when I press Next (button) I want it to check first if all information is given and in case its not, then you cant go to the next form before filling all information.
View 5 RepliesI have created a class called clsTest, this contains the sub "logInfo", when this is called within another class (e.g. "clsOther") some information about the other class is logged to a file.
I want clsTest to be able to get some general information about clsOther, specifically it's type and/or the sub/function that called the "logInfo" sub in clsTest. I could pass these as additional arguments in the "logInfo" subroutine but I was wondering if it was possible for clsTest to know what had invoked it (or any other class for that matter).
