Is it possible to do the following?
A user is prompt to enter a 3 digit code followed by a single letter, like this: 000A
is it possible to limit the input to the textbox to 4 characters? and is it also possible to create a function which detects which letter is at the end of the input so that it can put the data in the right place?
For example, if i have three folders, A folder, B Folder and C folder, can I create something to detect the last letter of the users input and based on that letter the input goes into the correct folder?
I want to be able to get the table structure / design / column information from an access database. I have created a post in the Database/Access section with no luck, here, but I am wondering if I could achieve this through vb (2008 express edition) rather than the access sql query itself. My overall goal is to compare one DB structure with another, an integrity check if you will.

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?

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).
I am working on a project in VB 2008 and need it to do this:Read first line from text file (using Openfile)Enter line into textbox on formDo some other codeThen Read second linefrom text fileEnter line into same text boxand loop until we have gone through text fileI am not sure how to read line by line from text file then enter it in textbox. I can open the Openfile and get the filename and everything, but I just am not sure how to read from it or enter that line into the textbox.Here is what I have, its not much but its a start:

I have a dictionary object (let's call it _do) I am using to cache some values for use in a multi-threaded program. I have a single controlling parent thread, with a timer function _doTimer() which can kick off child threads with a new instance of class MyThreadObject in each. My parent thread has _do as a property and with each time _doTimer() gets called, it may or may not repopulate _do depending on cacheflag settings. I pass a reference to _do to each instance of MyThreadObject and those threads at some point read the values of _do but DO NOT write to it.
What I want is to ensure that the child threads do not try and read _do whilst the parent thread is writing to it. Same thing but very slightly different -> I also don't want the parent thread to write to _do whilst the child threads are reading from it. However there is no problem with 1 child thread reading the values of _do at the same time as another child thread is reading the values - so ideally I do not want each child thread to completely lock out read access, only locking out Write access.. The code is roughly like this:

View 5 RepliesQuick 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
