VS 2008 Checking For Newest Text File For Input?
Dec 4, 2009
Can I set this function so that if the local settings.txt exists, it will NOT be overwritten unless the mapped file is newer?
If IO.File.Exists("C: empsettings.txt") = False Then
IO.File.Copy("K: empsettings.txt", "C: empsettings.txt")
ElseIf IO.File.Exists("C: empsettings.txt") = True Then
[Code]...
Currently modifying a program that is being used by several staff. Each time they restart it, it starts the latest build.
I have a settings.txt file that is needed for the latest build(not on all pc's yet, original version has the settings written in the code) and updated as needed.
If local PC doesn't have settings.txt, it is copied, if it does have settings.txt it gets overwritten by the mapped copy on each run.
Wanting to let users keep their 'personalized' local settings.txt, unless I add a new feature to the program that requires a change to the mapped settings.txt file.

For example, I clicked the Add Text box button, so it added 3 text boxes in the form (I used Dynamic text box so it can add multiple text box). When I input data to one of those 3 text boxes and then Save button has been clicked. It should checked whether the dynamic text boxes are empty or not. If there are empty text boxes, then saving data to db should not be continued and display a message telling the user that empty field(s) are invalid.
In the code below, it saves the data even if there are empty text boxes and I think because it is in the for loop, it checks the text boxes one by one and repeatedly displays the message box that I coded.
Here's the complete code:
Imports System.Data
Imports System.Data.SqlClient

I have been trying to check if a user has input a specific time format into a textbox.For example
1- User enters time in hhmm format
2- Checks the input
3- If wrong, MessageBox.Show("Need hh:mm time format")
I have only used IF statement with IsNumeric to check for number input but was unsuccessful with various attempts I can think of for checking a time format as I need Option Strict On and have the following error: Option Strict On disallows implicit conversions from 'String' to 'Date'.Is there a way to like check if the hh:mm has the ":" separator too?

I have 22 text boxes that have to be checked to see if the value has changed. I am using the TextChanged Event handler to do this thus:
Private Sub TextStringChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
DataChanged = True
RemoveHandler ........
[code]....
The Handler would be added after the data had been loaded. The question is:Is there another way of checking for text changes without having to add and remove 22 handlers.

I have a textbox which has a numeric value that changes - would it be possible to check if that value matches two numeric values in a text file? and if the value matches then to display some text in a label? The textfile only has fields displayed like so
Horizontal 55
Vertical 16
So I would only need to check if the numeric field in textbox matches the two numbers in the second column. In the past I have use System.IO.File to create/delete/append to files but I havent come across anything like contains.

I have text box in my program where I need the user to enter at least six characters. They also need to include at least one alphabetic and one numeric character.My idea is to create a loop that uses the IndexOf string manipulation to check each character. I'm familiar with the IsNumeric method .

I have the following line of code used to input the name of a text file to be opened and during development this was working without a problem. However when I create an executable this is not working and I was hoping someone would be able to give me a tip on resolving this matter.
Dim fileName As String = Application.StartupPath & "" & TextBox1.Text

I am trying to figure out how to read a text file and check the value entered into a textbox to see if it already exists. Its basically a validation list.
I found some code on how to read a text file, but I do not know what to do with the information.
Sub Main()
If RadioButton1.Focus = True Then
'Check TextBox1 value against list of known part numbers
[Code]...
How do I compare the textbox value to a line read from the file and stop if there is a match?

This question has been most likely been asked a number of times, but really hitting a brick wall regarding this.
The issue is that at the moment, I have to create a database using text files on VB.
So far I have managed to get the code working to add new customer and browse added records, but stuck on how to output/input back and fore to a text file, to store information, and after this input/output the text file to a DB ( Not worried about this at the moment)
Public Class Customer
Dim CmrColl As New Collection 'Create the new collection. Think of this as an array of objects.
Dim itemCount As Integer = 0 'A variable to help us scroll through the objects later.

I am wanting to write an application which opens a delimited text file (either comma, pipe, colon, semi colon) and displays the file on the form. The same feature is in Excel when you import a data file. After selecting the file it shows the contents and you can choose the delimiter. Once the delimiter is chosen the data shown reflects this and updates to show the correctly formatted data.

I need to get data from a text or excel file and input it into a windows program that I do not have source code for and cannot get it.What I am trying to do is get sales order data from one of our customers in a file and then read the file and input the order information into our sales order system by actually stepping through the order entry process so all the checks for item #'s, zip codes, etc that are already in the sales order entry software are utilized, basically so that data files integrity is maintained.
I am very green when it comes to programming, can anyone tell me if this can be done using vb.net or should I look into using another programming language.

I need to delete older bkf files in a directory, only leaving the newest 20.
No, I can not just delete older than x days because there can be more than one backup file per day and some times it may be 2-3 days before a backup file appears.

I have lines in my text file like this:
x y
x Y
x y
x y
x y
x y
x y
x y
x y
x y
x y
x y
x y
x y
x y
x y

Lets say I have 20 lines like this. I want to change this lines according to user input. So user will input how many lines they want to change in terms of row and column. In my program
Row=TextBox5.Text column=TextBox6.text
User must enter initial value for x and y. Let say the initial value is
x=1 y=1.
Row=2 column=5..
Now my lines should look like this.
1 1
2 1
3 1
4 1
5 1
1 2
2 2
3 2
4 2
5 2
x y
x y
x y
x y
x y
x y
x y
x y
x y
x y
Since I enter row=2 only two set of lines is change other lines remain unchange. But in my coding all the lines is changing like this:
1 1
2 1
3 1
4 1
5 1
1 2
2 2
3 2
4 2
5 2
1 3
2 3
3 3
4 3
5 3
1 4
2 4
3 4
4 4
5 5
which is wrong.
This is my code
Dim lines() As String = IO.File.ReadAllLines("C:\wirematches.txt")
Dim xValue As Decimal = Val(TextBox1.Text)
Dim yValue As Decimal = Val(TextBox2.Text)
Dim altValue As Decimal = 2.54
Dim lineTracker As Integer = 0
[Code] .....
This code working fine for changes the column. But i dont know where i should write the code for row.

I am trying to input a text file of figures into a 2-dimensional array. I want to do this so I will then perform percent changes on the respective columns. The text file contains columns and then numerous rows for each columns each number is separated with a tab. The text file looks something like this.
2.2 5.5
3.7 6.3
9.2 9.1
So I need to be able to input the text file, turn it into an array and then find the total percent change. From 2.2-3.7-9.2

For Each line As String In lines
Msg(line)
2) categorys inside a dll.
For example if the "line" string equals to car then find the category black and display it's contains. I would like the .dll to all contain this information. Both the car and the category. All i want is the main .exe to read the information.

Is there a simple way to save user input from MANY controls (textboxes, comboboxes, etc...) to a text file? When I say 'MANY', I am referring to at least 580 textboxes and several dozen comboboxes.
I may be able to accomplish this using the StreamWriter Class, but doing this individually would take quite a long time. I suppose I could also change all text boxes to richTextBoxes and save to .rtf. It seems like this would be even more time consuming.
Surely there is a simpler way to do this 'globally', perhaps with an added single line of code that points (and saves) to a preset or created text.txt file whenever text is added or changed in a textbox or combobox throughout the program.
