Read CSV File Into Array Sort / Add / Edit / Delete And Write Back To CSV

Aug 15, 2011

The gist of the program is to:

- Read a CSV file into an array
- Get this visible in a list box, so the values can be:

- Sorted
- Edited
- Deleted
- Added

- Finally save these manipulated values back to the text file

Would love some suggestions and code as to how to get this going, hopefully I'll get the hang of it and come back and fourth for help

Read Text File / Search For String Then Add To Line And Write Back?

Nov 18, 2010

I would like to read an HTML file, search each line to see if it starts with </head>. Then add the centering code after it. That line at destination file should read:
</head><table border="0" cellpadding="0" cellspacing="2" width="760"align="center"><tr><td>
After this I don't care to search for anything. Just read from source and write to destination. I know there are programs out there to find/replace text in series of files but I am not allowed to use external programs.

Use Textbox To Edit A Textfile Csv Which Has Been Read Into An Array?

Nov 28, 2010

I've got a csv text file "test.txt" in the following format with one record per line in the following format: Builder,Bob,B,99HappyStreet,Springtime,4

I've read them into an array and in design use the first two to populate a listbox and then use a selected index to fill text boxes and some list boxes.

ex. TextBox_FirstName.Text = Employees(ListBoxMain.SelectedIndex).FirstName

How do I write the changes made in the text fields back to the position in the file where it was? It has me stumped although I'm sure there is a SelectedIndex option that can work.

I've considered having all the new/changed data saved as a new record and then just deleting the 'old' entry but my delete code gives me a selectedindex-1 index out of range exception error that I'm working on as well. I am sure both problems are related.[cod]e...

Site Level Folder Read/write/delete Permissions From Webpage?

Dec 20, 2011

I have a link on a VB.net aspx page that needs to open a folder in a subdirectory of a web site and provide read and write permissions so that files can be copied into and read from as well as deleted. ONLY from this folder.I have this funtionality working on a dev and demo PC but they are both on my domain. Clicking the link opens Windows Explorer and I can copy /cut & Paste, etc.The public/production PC is on the LAN, but not part of the domain. I know there are ways to allow folder read/write permissions on a public server like this but I am not too sure on the safest way to do this. The upside, the only users that need to have read/write/delete access are employees. Forms Authentication, ASP Membership directs non-employees to other pages within the site. Likewise, the membership directs employees to an admin section of the site.

Jan 29, 2009

Sub Sort()
ReDim RollsCC(NumOfPlayers - 1)
For N As Integer = 0 To (NumOfPlayers - 1)[code]....

Here I am creating a temp single dimensional array, merging my 2d array into it, and then attempting to sort it by Rolls(N,1), which is a integer 1-6, Everything seems to be working right with the exception of this.

RollsCC.Sort(RollsCC, 0, 1)

How would one specify a numeral sort based on the first character in the string? im aware that I am switching Rolls(n,1) and Rolls(n,0) information during the sort.

Read Text File And Sort Data Between Two Characters?

Jun 12, 2011

I have a text document that contains a bunch of data sets. However before each data set there is a number surrounded by brackets. I need to go instance by instance of brackets and pull the number between the brackets and the lines after the brackets until the next bracket. Here is an example of the text file that contains the data. I know how to read from a text document, do substring, do contain function, etc... I just am extremely stumped on how to do this. Here is an example of a couple entries of the text document...

[4188]
LongName=
ShortName=
LauncherDirKey=

[Code]....

Notice how different sections have a different amount of lines therefore a reading a fixed number of lines is not an option.
