   Hi all,
   I am a new beginner of Visual basic 6. Even though i read James's article, i don't know how to create a project and add his code as a new module.
   Could you please show me how to create 1 project has 1 command button and 1 optionbox only? Also how to add James' s code to that project?Thanks for your time and understanding.

   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.

   I am using deppfreeze in my internet cafe.This program protects hard drive from every changes and does not allow save games.When computer restarted all saves dissapear from hard drive.I know the games save directories and i need visual basic code that copies all files in directory to server.Code must overwrite and must include subdirectories.As msdos command does :
   

   
   xcopy C:\Program Files\Call of Duty\Main\save*.*  \server\saves\call of duty /e/y
   

   
   (/e/y parameter is for overwrite and include subdirectory)
   

   
   Can anyone help me.Thnx.

   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
   

   
   Greg

   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'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?

   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 know how to get a list of files that are in a folder and put the file names into an array.

    It's too Late.i know .
    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....

    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

    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.

    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.

    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

    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
