asked on
selecting in pairs or displaying 2 rows in 2 columns
Hello,
i have a sequitial text file representing repairs budget looking like this:
kitchen
4500
diningroom
5322
living room
4567
the numbers represent the cost per project. I need to load the following file in to the form ( i am currently loading it in the listbox ).
The way i currently have it, is that the price and project represent different rows. This is uncomfortable for choosing the project from the list, as i will need to do some operations with the prices. It is also confusing for user, as he/she will not know whether to press on 4500 or kitchen to calculate the discount or additional expenses which will depend on the amount of time the project will take.
The condition is that i cannot change the text file, but --- i can change how it gets displayed in the listbox.
What i was thinking about, is iether by clicking on one of the rows, that will automatically select the 2 together or to display the 2 rows in 2 columns. And i need some help in how to create that. Also if you have any other ideas about the design please let me know.
Below is what i got so far, which loads all the rows as a separte item in the listbox.
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim sfiletocheck As String = Application.StartupPath & "\inputfile.txt"
If Not File.Exists(sfiletocheck) Then
MessageBox.Show("Cannot find the file. Please try again !")
Else
Dim writefile As StreamReader
Dim lineoftext As String
writefile = File.OpenText(Application.
lineoftext = writefile.ReadLine
If lineoftext <> Nothing Then
Do
Lsttext.Items.Add(lineofte
lineoftext = writefile.ReadLine
Loop Until lineoftext Is Nothing
End If
End If
End Sub

Sorry FSA7 I don't quite understand what you mean

I want in the lsttext click event to do smth like this:
Lsttext.SelectedItem = the cost of the project.
If i select kitchen ( which will be the first item in the list ) i want the value of it to be 4500 . But i want the values to be read from the text files and not manually assign each project to the cost.
I will be selecting the repair project and then dates, and after that the calculation per that period of time will give the final price for the project
let me know if i am unclear...

What i mean is that now the list items became a string and it is hard to extract the cost value from them to use in the calculations.

Like this ?
Dim sfiletocheck As String = "c:\test.txt"
If Not System.IO.File.Exists(sfil
MessageBox.Show("Cannot find the file. Please try again !")
Else
Dim writefile As System.IO.StreamReader
Dim lineoftext1 As String
Dim lineoftext2 As String
writefile = System.IO.File.OpenText("c
lineoftext1 = writefile.ReadLine
lineoftext2 = writefile.ReadLine
If lineoftext1 <> Nothing Then
Do
ListBox1.Items.Add(lineoft
lineoftext1 = writefile.ReadLine
lineoftext2 = writefile.ReadLine
Loop Until lineoftext1 Is Nothing
End If
End If
although maybe it is better to use a listview with 2 columns
