I'm trying to create a program, which would loop trough all letters. I want for example show aaaa, then aaab to aaaz, then aaba and so on to zzzz. The problem is: how to allow user to enter the letter count? Here's my code with only 3 letters:

create an XML file from a large Oracle dataset. The Oracle dataset contains an ID column and a bunch of different address types. For example, An ID will contain a primary address, secondary address, and a bill to address. Each of the three address types can have multiple addresses but I'm only retrieving the first three.Currently, I'm retrieving three of each address type then joining all of the data together. If I continue with this method, I would have to loop thru the dataset to find the ID and then loop thru the dataset again to find each address for each address type. This doesn't seem very efficient and I'm wondering if there is a better way to do this. Is there a better way to manage the data on the oracle side so that I can have one row for each ID? Or is there a better way to handle this on the .net side with collections and manipulating datasets?

Now I'm having some trouble displaying the output using the do while loop, and I'm pretty sure it's a loop problem on my code. However, I cannot seemed to find out what's wrong. I looked at the examples of do while loop in my textbook, but I couldn't find anything useful to my problems of my program.This is the output for the do while loop.

When I use a For loop in a For loop the Contains Statement dosen't work! Even my custom one! I even tested mine and it works 100% And neither that or the String.Contains function work inside of For Loops And, I know both of them use loops to search through a string.
My function(It will atleast search once):
Function RealContains(ByVal load As String, ByVal needle As String) As Boolean

View 3 RepliesI have a program that I am making and need it to be able to search a folder (within a given path, e.g. C:UsersAdminMy Pictures) and return a count of all the files in the folder that are of a certain association, e.g. jpg, into a variable.
The reason I want to do this is to create a photo album (bit like what you see on facebook) where the program searches a folder for all jpg files and loads the count into a variable. Then the user can scroll through the jpg's. I can already get the scrolling bit not a problem but that is only when I manually set the file count myself. Below is the code I use but I need to automate the maximum file count

I am working on a VB NET project and had the strangest thing happen.I created a class file(just like a dozen or so I have already created). I wrote in the code to access it. The autocomplete found the class, filled it in and colored it blue, just as it should.But, when I run the app, I get a type is undefined error.
There is nothing in the class yet. And there is really no code to post..it is as straight forward as I described.I tried restarting VS; Deleting and recreating the class; Deleting the class and creating a new one with a different name.
Is there something in the VB NET configuration I can check to see if it is not being added somewhere?
I found the problem. I have 2 projects in one solution. They both share some classes that were trying to use my new classes. When I hit F5, both projects are compiled, and since I hadn't shared the classes with the second project, it errored.
So, now my question is changed; How do I specify to only build the specified Startup Project when debugging?
Alright, so I've got my program and it works, but I have to pump out updates every once in a while. If I can get it so the code will let me have my text file with any number of lines for my array, then I can simply send out a text file and update done.So here's what my code does:
Define a record of arrays, two items, a unicode string (Japanese/Korean text) and then an English translation for the text.I read in the file, it's one item per line, unicode string and then the translation.I have it preset with a defined upper bound for my array, but if I just took out the define and leave the upper bound as limitless, then it would work if I just updated the text file. Problem is, I don't know how to do it with stream.reader (I think that's what it is) because I learned a different way in school. I want to do something like Do While Not EOF with this, and loop it reading lines from the file.
Would it work if I change the array to no upper bound and then simply use Do While Not EOF with stream reader?
I have three sets of labels, lbl_seconds, lbl_minutes and lbl_hours. These labels have the default value of 00:00 and I want the timer to change that for each label. I have googled this but I cannot seem to find any good info on it. Do I need three separate timers? I have also noticed that the timers have their own tick event handler. I guess it's in this that I need to change the value of the label. But I cannot figure out how to do just that.

I am currently attempting to create a VB.Net script that pulls up information on installed printers. I am using Visual Studio 2010 SP1, and as my target program needs to run on older machines, is currently built using .Net 3.5.Looking online, there are several methods on how to do this, one from url...the code is supposed to use System.Management as you can see. However, after importing System.Management, Visual Studio throws an error and states that ObjectQuery, ManagementObjectSearcher, and ManagementObject are not defined.a quick look at the MSDN forums shows that ObjectQuery is a class of .Net 4, 3.5, 3.0 and 2.I figured the error might be because I didn't have the .Net 3.5 SDK installed, so I installed the .Net 3.5 SP1 SDK to no avail.just to make clear, I am importing System.Management at the top "Imports System.Management"
