CSV Filename not working

VGonsalves — Fri, 10 May 2013 07:20:03 GMT

I am trying to write code to collect standard info from a csv file to be added to iProperties.

Following is the code I have so far.

Dim Separators() As Char = {"\"c} Words = ThisDoc.Path.Split(Separators) FilName = "C:\Vault\Designs\" & Words(3) & "\Spec_Sheet.csv"

Dim ReadCSV As New System.IO.StreamReader(FilName) Dim WordSets As New ArrayList()

Do While ReadCSV.Peek <> -1 WordSets.Add(ReadCSV.ReadLine.Split(",")) Loop

i = 0 SName = iProperties.Value("Project", "Stock Number")

For Each wrd In WordSets If WordSets.item(i)(0) = SName Then iProperties.Value("Project", "Description") = WordSets.item(i)(1) iProperties.Value("Custom", "Finish") = WordSets.item(i)(2) End If i += 1 Next

The only problem I have is that this line crashes. I am not competent enough to understand why. Can anyone help me

Dim ReadCSV As New System.IO.StreamReader(FilName)

Anyone......

I think a little error handling could help to solve your problem. Please see the included on a little more eligant way to handle this.

   Private Sub test()
        Dim Thisdoc As Document = ThisAppliocation.ActiveDocument
        Dim FilName As String = GetDirFromPath(Thisdoc.FullDocumentName) & "Spec_Sheet.csv"
        If My.Computer.FileSystem.FileExists(FilName) Then
            Dim WordSets As New ArrayList()
            Using ReadCSV As System.IO.StreamReader = New System.IO.StreamReader(FilName)
                Do While ReadCSV.Peek <> -1
                    WordSets.Add(ReadCSV.ReadLine.Split(","))
                Loop
                ' work with your word sets in this area

            End Using
        Else
            'FilName file did not exist. deal with this in this section or ignor it.
            MsgBox(String.Format("{0} does not exist", FilName), MsgBoxStyle.Information, "Error Reading File")
        End If

    End Sub


    Public Function GetDirFromPath(ByVal path As String) _
      As String

        Try
            Return path.Substring(0, path.LastIndexOf("\") + 1)

        Catch ex As Exception
            ' error
            Return ""
        End Try

    End Function

Hi Mike
Yes I think you have a elegant solution here. I will not be able to test it until I get back to work on Monday. I have studied the code and I think the directory structure is not what I am looking for... I didn't explain that in my previous post though
The csv file is located at C:\Vault\Designs\Project1\Spec_Sheet.csv but the reference part can be in the following locations
C:\Vault\Designs\Project1\Dir1\ipt or
C:\Vault\Designs\Project1\Dir1\Dir2\ipt or even further
So I am trying to track down to find the right project name directory. The only constant here is that from the ipt file path the third directory under C: is the location where the file is located. That is why I split the file name and rebuilt it. But then couldn't use the rebuilt name with StreamReader. I hope I have been able to explain myself. Hope you can help me with this one.
On a side note I am struggling to get to the help file for iLogic. Can you tell me if any exists? Or suggest a good place to find iLogic command help
Thank you for your help this far

Hi Mike

I have updated my code with your help. It looks like this and works.

DimSeparators()AsChar= {"\"c}  Words=ThisDoc.Path.Split(Separators)DimFilNameAsString="C:\Vault\Designs\"&Words(3)&"\Spec_Sheet.csv"
IfMy.Computer.FileSystem.FileExists(FilName)ThenDimWordSetsAsNewArrayList()UsingReadCSVAsSystem.IO.StreamReader=NewSystem.IO.StreamReader(FilName)DoWhileReadCSV.Peek<>-1WordSets.Add(ReadCSV.ReadLine.Split(","))Loop
    i=0SName=iProperties.Value("Project", "Stock Number")ForEachwrdInWordSetsIfWordSets.item(i)(0)=SNameTheniProperties.Value("Project", "Description")=WordSets.item(i)(1)iProperties.Value("Custom", "Finish")=WordSets.item(i)(2)EndIfi+=1NextEndUsingElse'FilName file did not exist. deal with this in this section or ignor it.MsgBox(String.Format("{0} does not exist", FilName), MsgBoxStyle.Information, "Error Reading File")EndIf

But I am still open to your suggestion of directory handling as outlined in my first reply to you.

Thank you
