I have data which can be put inside listboxes, I then proceed to save the data into a textfile then attempt to load it. This all works great until a number of over 1000 appears because it's read as 1,000 and VB thinks the Comma means to go onto the next field.
'put record into the line in correct format
sLine = sCallCentreOperatorID & "," & sCallCentreName & "," & sQuoteNumber
sRecord = reader.ReadLine

View 2 Repliesim working on a project that is calculating the total population for given countries and its in the hundreds of thousands. And i need to output the population with the ,'s in the appropriate places.Ex. population 123456789 i need to output it in a listbox as 123,456,789 so im looking for a converter function or something built in that takes my value

So basically I have two comboboxes. Combobox1 has these items in it:
Education and Health Services
Financial Activities
Professional and Business Services
[Code]....
I am trying to write a vb2008 program that allows a user to select an airport from a combobox and then once the value has been selected it searches a comma separated text file once it has found the airport selected ( always the first column in the file) in the file it populates 8 other textboxes with the row data from the file. The idea is to select the airport and then it calls up the radio frequencies associated with the airport.I assume you have to call the data into an array and the search thorough the array until the combobox.selectedvalue = the value in the array, but i am unsure how to do this Ideally I would like to be able to the user to add data to the file thats why I used a combox, but I am having trouble trying to get the boxes to populate so first things first.

Does anybody know how to to count the number of characters typed in a text file and display in a label? I'm making a simple application on vb 2008 that needs to calculate the number of characters in a text file. The user will enter the text file in a text box. The file will be located somewhere in my hard drive.

I have not had much time to go threw my code properly as this is some urgency. I need to remove line 1 from a textfile if it contains a string but its not working.I have 500 files and not going to do this manually.
Code:
Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click
If String.IsNullOrEmpty(txtDirectory.Text) Then
OpenFolderDialogDirectory()

I also feel the function is very pointless sime i am opening the file twice.
I made a program that generates random numbers and places the numbers in two separate labels.How can I make the number in the first label greater than the number in the second label.Here is my code for generating random numbers:

I want to make the first number greater than the second because the numbers should be subtracted .

i just need to get this block of codes out, and put it in a textfile. and my program will run without seeing it, because it's all saved in the textfile.
I am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???

If Splitter1.Location <= New System.Drawing.Point(184, 0) Then

Need to return the greater of 3 values. Each value is based on user input and system calculations. Requirement = the greater of (Req1, Req2, Req3) Have tried a number of "If" "Else" and Ifs within Ifs "<" and ">" combinations without consistant results. This may seem simple to some but I am relatively new to VB. My search on MSDN was not fruitful.
View 11 RepliesThis makes no since to me I have a textbox that the user will put in information that I need to cut off so I wrote this code
txtMatID.Text = Trim(Mid(txtMatID.Text, 1, (InStr(txtMatID.Text,
"-") - 1)))
The user will imput a number value then a - then some words after that. I just want the number value. But when I try to debug the app it breaks on this line of code with this error. Argument 'Length' must be greater or equal to zero.
In my decryption statement I am getting
Argument 'Length' must be greater or equal to zero. is this statement wrong
DecodedStr = Mid(DecodedStr, 1, InStr(DecodedStr, Right(DecodedStr, 4)) - 1)
I disabled an exception because it was bugging me i couldnt find an intermittent error. My program reads textmessages from a phone, however a problem sometimes arises, and I am slowly pinpointing the areas of the code that cause issues. I have found however that it is sometimes here:
'Get a string of certain length
Shared Function GetString(ByRef PDUCode As String, ByVal Length As Integer) As String
[Code]....
check to see if length is zero AND thereofre try again in a moment, (because it usually works second time for some reason). I can think how to get around the exception

View 2 RepliesI have two columns of numbers that hold team scores for different events. I am looking for a OO way to Color the textbox of the team with the highest score in each event. I know the following will not do it (without writing a complex set of If Then Statements) but I think it might paint a clearer picture of what I am trying to do.
VB
Private Sub ColorWinner(ByVal crtl01 As Control, ByVal crtl02 As Control)
If CDec(crtl01.Text) > CDec(crtl02.Text) Then
crtl01.BackColor = Color.Gold

The controls are always going to be text boxes. So basicaly I want to determine the text box with the highest value and act on it without having to write a complex series of nested IF Statements.

View 3 RepliesI thought I had this sussed until I then wanted to filter between two values or greater than or less than two values. I have searched and searched all over the web for this and I just go round in circles. This is so frustrating why is this so difficult to find something so basic (anyway that is my rant). I have something like this but am totally confused and do not understand what I am doing now: how I get this working in plain English.
Me.BindingSource.Filter = String.Format("DeliveryDate >= #{0:MMM/dd/yyyy}# And DeliveryDate <= #{1:MMM/dd/yyyy}#", dtpStartDelDate.Value.Date, dtpEndDelDate.Value.Date) _
& String.Format("JobID >= {0} AND JobID <= {1}", txtStartJobID.Text, txtEndJobID.Text)
If I run this with just the date range filter it works fine it is when I add the second filter for the Job ID range I get the following error; {"Syntax error: Missing operand after 'JobID' operator."}
So I it is this line I have the problem with:
String.Format("JobID >= {0} AND JobID <= {1}", txtStartJobID.Text, txtEndJobID.Text)
Can I do this to find the lowest value in an array greater than zero?
Dim findLowest() As Integer = {right, left, backRight, backLeft}
Dim theMove As Integer = findLowest.Min > 0
Can't seem to find it on MSDN.

View 6 RepliesI have a datagridview where I have added a filter. What I am trying to do if the user leaves the field blank I want all the records to show. The field I am filtering on is an integer. I thought I could declare a variable and if the field is blank include all records greater than 0. This would return all records as the number will never be below 0. I tried this but can't get it to work:
HTML
If txtFiltID.Text = "" Then
sSerialID > 0
Else
sSerialID = txtFiltID.Text
End If
'Refresh dgv on filtered criteria
Me.VJobLinesTableAdapter.FillByFilter(Me.DsJobs.vJobLines, sSerialNo)
It works fine if the user enters a value.
