    Hello


    I would like to know, how to read a file in binary mode, the other
    way around ( from the end to the beginning of the file).


    Thanks in advance

    After all the search I think I found something very complete, "friendly" speech, and lots of examples.


    This is what I look in a book/tutorial or whatever.


    Congrats to the author

    If the program has multiple files open at the same time, how do I find the files nFileNum identifier so I can close a particular one?


    Is there a piece of code that can return this?


    I have the names and addresses of the files stored in an array, might be of a use.


    Thanks buddeh, the rest of it really helped

    First you need the filesize, I forget how to find it so we'll assume it's 20 bytes. ^_^; Then you'll need enough memory to hold it all. In this case to make things simple, we'll output the data to another file.


    offset = 20
    offset2 = 1
    do while offset >0
    get #1, offset, variable
    put #2, offset2, variable
    offset = offset - 1
    offset2 = offset2 + 1
    loop


    Something along those lines should work, I'm a little rusty. I just stared a week or two ago.

    I think nFileNum is just a variable for the file number, for another file you'd have to use something else. I'm probably wrong though.

    You're right, but it's not what I meant.


    I wanted a way of finding what the Filenumber of a particular file was.


    Doesn't matter now though, I found a way around it and have finished the program entirely.


    lol, thanks anyway

    If you really want to hide some files and FOLDERS from your computer, other than do it yourself....you could download a Wonderful program from PCMagic's MAGIC FOLDER....

    Function GetFileList(FileSpec As String) As Variant
    '   Returns an array of filenames that match FileSpec
    '   If no matching files are found, it returns False


       Dim FileArray() As Variant
       Dim FileCount As Integer
       Dim FileName As String
       
       On Error GoTo NoFilesFound


       FileCount = 0
       FileName = Dir(FileSpec)
       If FileName = "" Then GoTo NoFilesFound
       
    '   Loop until no more matching files are found
       Do While FileName <> ""
           FileCount = FileCount + 1
           ReDim Preserve FileArray(1 To FileCount)
           FileArray(FileCount) = FileName
           FileName = Dir()
       Loop
       GetFileList = FileArray
       Exit Function


    '   Error handler

    Hello there...


    I have problems manipulating very big text files (I´m talking about files around 10 MB of plain text!!) and I have  to find certain kind of words in the document (parse).


    The files have a columns format (like vectors):


    Var1      Var2      Var3     ....   Var10
    Value1   Value1   Value1  ....   Value1
    Value2   Value2   Value2  ....   Value2
    Value3   Value3   Value3  ....   Value3
    ...          ...          ...                ...
    ValueN   ValueN   ValueN  ....   ValueN


    ///--------Comment line-----///


    Var11      Var12      Var13     ....   Var20
    and so on...


    I can calculate the size of the vectors because they have the same size, but I don't know how many "keywords" are because they vary file to file...


    Currently I'm reading the files Line by Line... and it's like hell!!
    I found in a book that I can open the file using the Random Method and the Get and Seek functions but I don't know exactly how to use them.


    Thanks in advance!!

    I'd like to allow a user to select a directory path, then parse a bunch of files in that directory. I have the parsing part down, and I can hard code a directory in just fine, however I need to enable people to select a directory in order to make this mini-app useful.


    ...My issue is two fold,


    1. I need direction as to how to create a form in VB that will give users the ability to select a directoy. (I am new to vb, and not sure where to start. I am not asking anyone to do it for me, but if you could point me to a tutorial, example online that would help it'd be great.


    2.  I am using the ".LookIn = """ command to specify a directory right now. I am having problems specifying a variable (E.g. Dir = "C:/folder/subfolder", then .LookIn = Dir) doesn't seem to work) Any ideas as to why?

    Ok, for those of us who are begining like me, I was able to find my mistake for number 2.  I simply had the syntax mixed up for the Dir function..I thought I could use it as a variable name...I was wrong.


    Dim fp ' declare my variable that I want to use for the directory


    fp = Dir("C:\work\venturaModify\06144") ' Set the variable equal to "a directory. This is where I am trying to make the user select this path, instead of me hardcoding it in.


    ...further into the "FileSearch" function I set the directory like this:


    .LookIn = Dir(fp)


    ...I am still struggling with my forms..I went through the tutorial by James, but haven't found anything online about selecting a Path via a form I can create.

    I've been able to follow your examples regarding making directories and renaming.


    I would like to know two more things.


    One: How do I check for a directory?
    Reason: I am developing a database that will need to check for a directory's existance using the current month's name as its lable. If the a directory does not exist with the current month's name - I will have code automatically create a new directory using the current month's name each time a new calendar month begins and identified by the system.


    Two: Can I use wild cards? Basically can I do the following in VBA -


    FileCopy "C:\Foldername*.", "D:\DifferentFoldername*."


    Thanks

    Hello,


    the article of James is not state of the art.
    To import win32 functions is not the way how you should work with the .NET framework. With a little bit pation you can write a own managed code assemby for INI Files.
