[RESOLVED] Error during Run-Time

I built, compiled, and ran the application error-free on my Win2k PC. When I load the application on a WinXP PC I error out 'File not Found'. I can not find any reason for the error. below is the code the form consist of a text box "text1" and two timers.

vb Code:

Option Explicit
Dim DelFiles(0 To 100) As String
Dim FS As New FileSystemObject
Dim FSfolder As Folder
Dim File As File
 
Private Sub Form_Load()
Dim strStartPath As String
    strStartPath = "C:\invprnt"
    Call ListFolder(strStartPath)
End Sub
 
Private Sub ListFolder(sFolderPath As String)
    
    Dim i As Integer
    Dim Cnt As Integer
    Dim Cmd As String
    
    Cmd = "c:\dosprint\dosprinter /raw "
    Cnt = 0
    StrtTime.Enabled = False
    Set FSfolder = FS.GetFolder(sFolderPath)
    
        Text1.Text = ""
        For Each File In FSfolder.Files
            DoEvents
            Text1.Text = Text1.Text & File & vbCrLf
            Shell (Cmd & File)
            DelFiles(Cnt) = File
            Cnt = Cnt + 1
        Next File
        
    Timer.Enabled = True
End Sub
 
Private Sub StrtTime_Timer()
StrtTime.Enabled = False
Call ListFolder("c:\invprnt")
End Sub
 
Private Sub Timer_Timer()
    Dim Flag As Boolean
    Dim Cnt As Integer
    Timer.Enabled = False
    
    Flag = True
    Cnt = 0
    
    Do While Flag = True And Cnt < 101
        If IsNull(DelFiles(Cnt)) = True Or DelFiles(Cnt) = "" Then
            Flag = False
        Else
            Call FileCopy(DelFiles(Cnt), "c:\bkupinv\" & Right(DelFiles(Cnt), 11))
            Cnt = Cnt + 1
            
        End If
    Loop
            
    Flag = True
    Cnt = 0
    
    Do While Flag = True And Cnt < 101
        If IsNull(DelFiles(Cnt)) = True Or DelFiles(Cnt) = "" Then
            Flag = False
        Else
            Call Kill(DelFiles(Cnt))
            Cnt = Cnt + 1
        End If
    Loop
    Cnt = Cnt - 1
    Do While Cnt >= 0
        DelFiles(Cnt) = ""
        Cnt = Cnt - 1
    Loop
    StrtTime.Enabled = True
End Sub

Thanks for any suggestions

-RT

You have hardcoded file path more than once so one of them is failing I guess:

strStartPath = "C:\invprnt"
Cmd = "c:\dosprint\dosprinter /raw "
Call ListFolder("c:\invprnt")
Call FileCopy(DelFiles(Cnt), "c:\bkupinv\" & Right(DelFiles(Cnt), 11))

-The application watches a folder "c:\invprnt" for a file to be saved to it

-If it finds a file then the app shells a cmd line "c:\dosprint\dosprinter /raw c:\invprnt" This prints the txt document to the printer in raw format

-the file is then saved to "c:\bkupinv"

-and finally deleted from "c:\invprnt"


This is why there is more than one path. They are all needed and are all present on the PC giving errors.

File not found is generated from one of two things and only two things:

1. The folder path does not exist
2. The file name does not exist

One of those two are not present on this machine.

Is this the only machine on which this is happening?

Also, why does this result in an runtime error? Why don't you have your code error trapped so runtimes don't happen?

When you "Load" your application on the other machine are you creating an installation package or just copying the exe?

Are you creating the folders you are watching if they do not exist?

On which line is the error happening?

The main problem is me not thinking. The problem occurred on line 53. The app copies a file, whose name is 7 characters long, from one folder to another. In testing I created a txt file in the source folder and named it test.txt |note: that test is not 7 characters.

This problem has been resolved. Much thanks to all.
