    Resolved [RESOLVED] VB Runtime error 75

    Hi once more, I am in a very irritating situation whereby I run code on my development machine I get no error, However when I try it on a test machine I get vb runtime error stating path not found. I have added the Microsoft scripting runtime reference and even included VB6 service pack 5 but dont get any change. The only difference I got on one of my test machines is that when I compiled it the the code ran pretty well, and on similar machines (ie same specs). The code in question shown below. Cheers
    VB Code:
    1. Function OpenNotices(filename As String)
    2. Dim InfoLine As String, a As Integer
    3. [COLOR=Red]Open filename For Input As #1[/COLOR]' here the line
    4. Do Until EOF(1)
    5. DoEvents
    6. Line Input #1, InfoLine
    7. a = a + 1
    8. AddToList InfoLine, a
    9. Loop
    10. Close #1
    11. End Function

    runtime error 75 isn't file not found

    anyway, is filename a valid file on the test computer? what do you get if you put MsgBox filename before the Open statement, does it show a valid file path?

    Hi Bushmobile and Co the site denied me giving some rates anyway I will sort that out. G thanks for the trick supplied in your answer it did get me well ahead. However when I use the "Msg filename", it gives me the location of the same path I use for file on developer machine and test machine. What could be the problem and what possible remedies can one execute to avoid such an issue. Cheers.

    Re: VB Runtime error 75

    Does the folder and file actually exist?
    Post the filename you got in your message (Debug.Print Filename).

    Re: VB Runtime error 75

    If you wrap this If statement around it:
    VB Code:
    1. If Dir(FileName) <> vbNullString Then
    2.     'code to open file
    3. Else
    4.     MsgBox "file doesn't exist"
    5. End If
    Will you still get the error and will the code be executed?
    (put a break on that line)

    Re: VB Runtime error 75

    I out there and thanks for the interesting tips and tricks coupling Bushmobiles and Jeroen79's tips I got this line
    VB Code:
    1. Msg Dir(filename )
    before the code and ........................ on behold I got the name of a different file in the same Directory as the file I was actually looking for. The only eyebrow raising issue is that they are both text files. Interesting, however from here what next ? Cheers

    Re: VB Runtime error 75

    Afetr changing the directories of all similar text files, the string instead opens a completely different file *.ico whreas I am looking for a *.txt file in the same folder which Does exist with valid Directory. This really is an issue. Cheers

    Re: VB Runtime error 75

    It is however really amazing how one would ignore the simple things like posting what is in the filename before it is attempted to be opened. There is no way one filename is passed and another opened.

    Re: VB Runtime error 75

    Thanks for the the support Randem. Actually there is memo information in the file hence its not empty. Hence it had stored the last entry I posted into. As to getting to open the file while making sure other similar situations must be closed I think the whole stretch of code will do to sort this out.
    VB Code:
    1. Public IconObject As Object
    2. Private Sub cmdAdd_Click()
    3. If sDate(0).Value = True Then
    4. AddNotice txtName.Text, Date, txtTime.Text, txtAbout.Text
    5. Restore
    6. Else
    7. If txtName.Text <> "" Then
    8. AddNotice txtName.Text, txtDate.Text, txtTime.Text, txtAbout.Text
    9. Restore
    10. Else
    11. End If

    Re: VB Runtime error 75

    It' still the same solution:
    VB Code:
    1. filename = getstring(HKEY_LOCAL_MACHINE, "Software\ReXz\", "Notices")
    2. Debug.Print filename
    3. OpenNotices filename
    Then post what gets printed to the immediate window in the IDE. Of course put a breakpoint on the OpenNotices line. I imagine this is where you are having the problem???

    Re: VB Runtime error 75

    it is better to post the code you use to build the file name you are going to open, the problem is there

    there are many debugging techniqus you can use to figure out where the wrong code

    from Debug menu add break points on the lines you are doubt on it, and when the execution break check your variables if it contains the expected data or not

    also you can use Add Watch... from Debug menu to add a variable that you want to watch and select Break When Value Change option, if you use a public variable its value maybe changed in unexpected places

    also there is debug step into (F8) it is very useful too

    Good Luck

    Re: VB Runtime error 75

    Well, after review your code i cannot figure out where the problem
    anyway i discovered something wrong, i doubt it cause all these proplems, that is you always using App.Path & "\file_name" indeed using App.Path this way is wrong and can cause many errors
    imagine that your exe is in the drive root dir say "C:\", in this case App.Path will return C:\ not C: as you expected. So exprisson like this App.Path & "\notes.txt" will return C:\\notes.txt

    therefore i have create a function to return the correct path

    VB Code:
    1. Public Function GetAppPath() As String
    2.     Dim strPath As String
    3.     strPath = App.Path
    4.     If Right$(strPath, 1) = "\" Then
    5.         GetAppPath = strPath
    6.     Else
    7.         GetAppPath = strPath & "\"
    8.     End If
    9. End Function

    use it like this
    VB Code:
    1. Open GetAppPath & "notes.txt" For Output As #1

    Re: [RESOLVED] VB Runtime error 75

    don't use a Function (otherwise you have to run the code everytime):
    VB Code:
    1. ' In a module
    2. Public AppPath As String
    3.  
    4. ' In your start-up sub, e.g.
    5. Private Sub Form_Load()
    6.     If Right$(App.Path, 1) = "\" Then AppPath = App.Path Else AppPath = App.Path & "\"
    7. End Sub
    Now whenever you come to use App.Path use AppPath instead

    Re: [RESOLVED] VB Runtime error 75

    The App.Path situation is from earlier OS handling App.Path differently So that routine should be mandatory. I have one like that that all my apps use. I set up a variable at the beginning of my programs that contain the newly create App.Path and use that everytime I want to use the application path name.

    Ex.
    VB Code:
    1. 'in a Sub Main
    2. Public gblAppPath as string
    3.  
    4. Private Sub Main
    5.  
    6. gblAppPath = GetAppPath
    7.  
    8. End Sub
    9.  
    10.  
    11. Private Function GetAppPath() As String
    12.     Dim strPath As String
    13.     strPath = App.Path
    14.     If Right$(strPath, 1) = "\" Then
    15.         GetAppPath = strPath
    16.     Else
    17.         GetAppPath = strPath & "\"
    18.     End If
    19. End Function

    I would then use gblAppPath everywhere that you currently use App.Path.

    Yo, Randem ure back,thank you all for your relentless assistance in the abovementioned issue. I have not only learnt some new tricks but enjoyed a slightly debated aproach. For all of you who have contibuted, Bushmobile,4x2y, randem, jeroen and Co, ure assistance has been worthwhile. Not only have I ended up with a solution to my problem I have gained a number of similar approaches to such scenarios and will take my time to appreciate all. Cheers
