Hi,
Good morning! I cannot make .readline to work for the program i am making. There is a text file that i needed to read the content and compare it to another value. If i try to output it to a msgbox the message is null even if the text file has a lot of text in it. that means it didn't read any line on the text file. Thank you so much.

Hello Roger,
I have a bunch of questions for you:
1. Do you use Add-in Express? What version and build number of Add-in Express do you use?
2. Do you develop a COM add-in?
3. Could you tell me where in the code do you try to read a file?
4. May I see the code snippet? |

Hi Eugene,
I'm using an add-in it is the latest version. It is COM add-in.
Dim FILE_NAME As String = getVirt() & "\ErrDesc.txt"
Dim Di As Integer
Dim Num As String
Dim Desc As String
Dim Errdate As String
Dim ErrFile As String
Dim ErrNum As Integer
Dim ErrWrite As String
Dim textLine As String = ""
Dim objWriter As New System.IO.StreamWriter(FILE_NAME, True)
Dim objReader As New System.IO.StreamReader(FILE_NAME)
Di = Err.LastDllError
Desc = strErrDesc
Errdate = Date.Today
ErrFile = lngErrNo
Do While objReader.Peek <> -1
MsgBox(objReader.ReadLine())
<----here's the problem, messagebox is null.
textLine =(objReader.Readline() & vbNewLine <---- the Readline should store its message here.
MsgBox(Err.LastDllError & "---" & Err.ToString & "---" & strErrDesc)
ErrWrite = (ErrNum.ToString & " ------- " & Desc & " ------- " & ErrFile & " ------- " & Err.Erl.ToString & " ------- " & " ------- " & Errdate & " ------ ")
<-----it will be use here to compare the current error to the error that has occured.
If ErrWrite.ToString = textLine Then
MsgBox("This error has occured")
objReader.Close()
objWriter.Close()
Exit Sub
Else
objWriter.WriteLine(ErrWrite) '(ErrNum.ToString & " ------- " & Desc & " ------- " & ErrFile & " ------- " & Err.Erl.ToString & " ------- " & " ------- " & Errdate & " ------ ")
objReader.Close()
objWriter.Close()
MsgBox("sample")
Exit Sub
End If
Num += 1
Loop
Else
MsgBox("File Does Not Exist!")
End If
End If
my coding it is a mess right now i cant continue with the code unless i've figure out how to read the line. Thank you. |

I've solved(I simplified the code) the problem now but another came out. I will try to go figure it out again. I will keep you updated. Thank you. |
