Looping Through Files And Get The Biggest?
Jun 28, 2011
I am new to VB.NET and have been given a project to do and am almost done but there is a part where I am struggling with , cant seem to find a solution.There is a server (\\ntklppt1\download) where my client downloads files on a daily basis. So in a month we receive maximum of 31 files in this formatabs_prod_20110601, abs_prod_20110602, abs_prod_20110603 abs_prod_20110626, abs_prod_20110627, etc.So what my application must do is, if I am now in June, the application must read all files downloaded from the 1st to the 31st of May and take the biggest file and import it to the database.

I am developing a package in SSIS (Sql Server Integration Services) part of which uses something called a Script Task (a component in which you can program via VB). In any event, for this component I need some code that basically loops through files in a folder and changes all text right of the first decimal point (in the file name) to ".txt". I am currently doing this via VBA in Access but am moving the process to SQL Server.

I know I've asked this before and for some reason I can never remember how to do it. I need to loop thru a directory structure and for every *.txt file, I need to open it and read it. This is a little application that basically searches for a given string. How do I do this?

I have like a collection of numbers like in a hashtable for instance
Code:key / val----+------ 1 / 2349 2 / 939 3 / 49444 4 / 93 5 / 114

Code:For Each dict As DictionaryEntry In htNumbers

Suppose I have 5 Integers(A, B, C, D, and E) and 5 Textboxes. When the program run, the user is going to input 5 numbers to those 5 textboxes. When a button is pressed, a label will show up and write the textbox number with the biggest number.

I am attempting to play a set of audio files continuously using a tree view. I am having troubles looping through an array to play one song after another in the selected parent node. It seems to work if I only use one song in the array but it doesn't want to actually loop through and keep playing; it goes through the loop but once the first song is over it stops. I am unsure if looping through an array in the AfterSelect sub routine is the best way of doing this,
Here is the entire Sub routine for the AfterSelect on the tree view.trvMain is the name of the entire tree view.wmpMain is the Windows Media Player COM.trvJazzHancock is the parent node for the two audio files I'm attempting to loop.

This is the code I'm using:

I'm building a slot machine, and I'm having some trouble.re's the
'Pulls down the slot
If e.KeyCode = Keys.Space Then
PictureBox2.Focus()

When I debug and click space down, my picture box of the knob slides on down to 175, pauses, and shoots back up. The problem I'm running into, is that it doesn't do anything if I try to pull the knob down again. It doesn't bug out or anything, but it just doesn't do it again

I'm trying to write a program right now for my computer science class for a program where you insert text into a text box, (the text being a password), and then click a submit button. The goal of the assignment is to have a program that looks at the user given password and see if it matches the const password (or one of the three const passwords in my case). If it doesn't, it is supposed to loop back so you can re-input the password. Also, If you enter the correct password, the loop ends and you are to get a msgbox (or, in my case three different ones), and then the application closes. We are to write the code so that if the password is wrong "x" (insert 3 as the number I have chosen), a MsgBox will pop up with a message saying
something along the lines of "you have gotten the password wrong to many times.", and then the application is supposed to close. I don't think I could rant on much more, I've done a good (or in my eyes terrible) job of summarizing the assignment.
[Code]...
My problem (aside from, I don't know, a problem with my code itself) is that when It reaches the loop, it goes through all the code again, but I'm unable to change the user given password, and so it just pops up the three failed password entry MsgBoxes (the code for which is temporarily removed), then the failed to many times MsgBox, OR one of the successful message boxes. What I'm wondering is if anyone can help me fix my code so that it functions as desired.

I need a loop to run in the background while my app. is running. The loop has to constantly check for the value of a var and return a value based on the values of the var.
Can a Loop be running constantly without slowing the PC down?

I have a listbox with SelectionMode = MultiExtended. I am trying to capture all the selected values to end up with 1 variable that includes all the selections in the listbox.I'm getting error "Public member 'Selected' on type 'String' not found." at the start of my If statement
Code:
For iLoop = 0 To Me.lstVDN.Items.Count - 1
If Me.lstVDN.Items(iLoop).Selected Then
VDN = VDN & Mid(Me.lstVDN.Items(iLoop).Value, 1, 5) & "','"

On a form I have a series of 20 checkboxes (cbS1 through cbS20). With that I have an integer named 'Count'
What I need to do: When the forms loads it will get a value for Count. I need all the checkboxes that are greater than this value to be checked.
So if count = 7 then cbS8 through cbS20 will be checked.
Im not really sure the best way to code this is. I know I can do it with a giant case statement...but there has got to be a better way right?

I have a csv file with data in it in the format...
EVENT|RUNNER|ODDS
1 - 2 - 1
1 - 2 - 3
1 - 2 - 5
[Code].....
So basically the data contains events, runners and odds. I'm looping through and assigning the variables to the relevant object propeties, alls fine.
The problem comes when I'm checking the next runner id (or event id) to see if it's changed so that I know to create a new object. Well in checking that the id has changed I've already moved one record too far so every time I'm changing to a new id I'm losing one record.

This is for .net frameworke 3.5 and visual studio 2008 in VB.Net.Two things we would like to do: 1) loop repeating node blocks 2) loop (through repeating node blocks) within repeating node block loop
First thing:
How do you loop through an xml that has repeating node block (<STRUS name="1000A") and extract the following node? For example you want to extract the IdentificationCode in the node that has <SVALU name="ZRT" and is from pos="9".So, the following example has the IdentificationCodes (TGJ23, PGA12, TPX12)
<?xml version="1.0" encoding="UTF-8"?>
<DocSplitterReport xmlns:xsi="http://www.w3.org/2001/X .......
<STRUS name="ROOT" lineStart="-1" lineEnd="-1">
<STRUS name="TAC" lineStart="1" lineEnd="194">
<SVALUs>

I have an array structure called Survey and I'm attempting to loop through all the data and get it printed out. I'm trying to follow the example in my text but I must have something different.Here is my basic structure:
Structure Survey
Dim ID_Code As Integer
Dim Members As Integer
[code]....
I'm not understanding how to fix? The objects and properties to the right of "Family Size: " are getting errors saying "Value of type Integer cannot be converted to System.Drawing.Font.
e.Graphics.DrawString("Family Size: " + Home.Members, PrintFont, Brushes.Black, HorizPrintLocation, VertPrintLocation)
VertPrintLocation = VertPrintLocation + LineHeight

I posted earlier with a question which was answered quickly and allowed me to fire through almost me entire program There is one last tiny thing I'm having real trouble with.I'm allowing users to search through my XML document for records. I can successfully search through the first record but my loop won't allow the search to go through the other 2 records.[code]It isn't the most efficient code to look at I know.As I said I can successfully search the first record but won't allow me to loop into the 2nd or 3rd record available.I don't know if my loop is wrong or if there is some bad placement with the code.
