Folder/file Processing - Open A .txt File And Add The Extra Lines To It?
May 13, 2010
what im trying to do and what i have done so far is probably a little backwards not sure sure how to id it any other way.when the user generates an error because a particular file doenst exist ive got my dialoge box to generate an .txt file for each file it errors on, so that the administrator can check and update missing files as an when - shouldnt be many files missing in the first place, should just be new product ranges or item just launched.what im stuck on is:
1. is there a better way
2. how do i open a .txt file and add the extra lines to it, so i re use the file but keeping the previous data.
I have a folder with several textfiles. The only thing i need from the files is the last 10-15 lines from each file, printed into a new file. There is a sentence that is uniqe inside (but the same for all) at the line i want to start copying from.In other words i need to seach for a spesific word, copy everything from that line to the end of document, and print that to a new doc. Repeated for all files in the current folder.
Im a college student and this is my first programming class, i am having extremely diffcult time with arrays and sequential file processing. Im not asking for the whole program, just something to get me started and hints along as i progress with it. Please help me get started on my program, its due in 2 days.
Here are the requirements....
1. The program must input any number of individual�s last and first names using two separate textboxes. 2. The array of names must be sorted by the last name using a bubble sort. You must code the sort. 3. The program must be able to recall the names from the file and add to the existing list of names so that more names can be added to, sorted, and written back to the file in sorted order. 4. Sort in ascending order: A to Z 5. All names must be displayed in a listbox in sorted order when the user wishes to see them. 6. In the listbox the last and first names must be separated by a comma and a space. Example: Smith, Mary 7. The user must be able to search for a name in the array, using the binary search algorithm. You must code the search. 8. Do not use module-level variables. Instead you may choose to use Static. 9. The program must be designed using Visual Basic 2008
I'm a complete novice with VB and any coding in general, but as life will have it, I have to create a program for my Final Year Project at university.In short, the idea is to open a file that has many lines of numerical data, then select the required lines, do some calculations on them and write it into a new file, but the new file must have its own format and the calculations must go into the correct lines.
Im struggling really with how to get it to read the file and then write the new one. Currently I have it so the user can open the file and it will display the data into a text box. I want to then be able to click another button that will convert that data into a new type, and in turn display that in another text box. Then have a save button to save the newly created data. This is what I have so far...(it's not much.I havent really got much of a clue what I am doing lol)
I am trying to make a script to spit command lines to a bat file to compress a bunch of files singly and then delete the original ones. I am sure that is easy to most of you, but I living a ____ trying to do this. A have a file list like this one belo, which was created with a command -- Dir /b /s /a-D N: > filelist.txt
I have a product.pdf in my clientbin(silverlight) folder which contains detail about product on click of button just i want to open that pdf i used following code it's working fine locally after hosting it is giving HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

I would like to place the code below in a click event for a button to open a word file. I have added the document (group2.doc) to the Application folder of the target machine in my setup project. how do I write a dynamic file path that will open the file?
I am building archiving system, I store the files on shared folder on windows server 2003, the shared folder protected by one user name and password ,on LAN I need vb.net windows forms to open file inside shared folder, how I could open the shared folder and in same time providing windows server 2003 with user name and password for the shared folder
I have a folder save here: C:MyFiles/And in that folder I have a few .txt files.I am looking to see what would be the best way to open each .txt file in that folder and search for the value Error or Warning and then when it does it must tell me what files do contain those words.What would be my best option? To create a Stored Procedure with t-sql to do this? or To create a .exe with C# or VB.net code.
The specific features I want to produce is it doesn't place on the form, it places in the little box at the bottom and when CustomUserControl.Show() is called it shows as a dialog boxI'm sorry if I misspelled something or my grammar is wrong, I've never done well in those subjects.
By using the code below i was able to open the folder and highlight the file that I wanted.The only problem is that I had multiple Explorer.exe's in my task manager.o my question is How can I open a folder and select the file within without Running a new explorer process? or Highlight a file in a folder that is already been opened previously
I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then

The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.
I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

This is a module I made to write to a .txt file. Every time it adds a new line with null value. wouldn't really bother me but it adds but then something that only suppose to have like 3 lines in it ends up with 5000 over time, anyone know how to not add that extra line while writing file?
I have an array called lines() which is basically an array indicating which lines to read from a file. for example lines(1) = 0 means 'read the first line from the file', lines(2) = 4 means 'read the 5th line from the file' (counting from 0 not 1) The program first reads the file (which has a lot of random lines) so it can identify which lines match my criteria. The way I store the line positions is this:
For i = 0 to noOfLines -1 'total num of lines in file If count = match Then 'this is my match criteria lines(x) = i 'store the line in the array
I a very large text document, I need to read some lines and at the end of each line, insert a text from the header of each page to he preceding lines.I have the following code the reads the file and displays it on a list box.Public Class Dialogs..[code]
