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.

2008 Array Processing and Sequential File Processing
View 14 Replies
May 19, 2011
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)

How do I open this .REG file in Visual Basic 2010?
I'm trying to make a program that will launch this registry file that I've put already in the Resources folder of the program.
BTW if you're curious it's not a harmful program I'm making.
So all I've done so far is put the file in the resources folder of the program, but I don't know how to actually launch it.

To create a Stored Procedure with t-sql to do this? or To create a .exe with C# or VB.net code.

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
[code]....
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.

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
