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.

I have thios code that will load a php file (text file) into a sting via streamreader then its supposed to find and replace a portion of the text and write the changes back out to the file via streamwriter. I put my code together and after running it look at the file and it's unchanged. After looking closer it appears the problem is the find & replace operation I am doing on the string. Here is my code:

How can I write and read a string array to a text file?

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

I'm writing on a texthandler-project for Vista.(Compiler : Visual Studio 2010-vb)My code must write a string back to file after trimming. I've decided to run the application as a full trust app. The code obtains the permission via fileiopermission,but still the result is:Acces is denied/Unauthorizedaccessexception (It's not Readonly).

I just joined this forum as I've been looking for a nice and serious VB forum for a long time
I'm having troubles making a program to search a text file line by line for a specific string.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim objReader As New System.IO.StreamReader("C: est.txt")
[Code]...
as you can see in the code its supposed to read a text file and if the line contains the same string as in the textbox then its gonna make a messagebox.
now the problem, if the line does not contain the specific string but the next or any line other line does, then it should automatically read the next line on "Else" and that's where I'm lost
for a "Readnextline" command or something like that?

Ok, I saw this code on the net
Dim sFileName As String
Dim srFileReader As System.IO.StreamReader
Dim sInputLine As String
sFileName = "D:UsersArbenDesktopSerieA.txt"
srFileReader = System.IO.File.OpenText(sFileName)
[Code]...
under the code I pasted at the top, but I get the text on line1 in all labels, like all labels become 1, while the text should be 1, 2, 3 and so on. So anyone can help me do that, each label gets the value of the next line in the txt file

I must read the file scan for value T250,T169,T168,T170,T176............which ever value start with T after the line"DETECT,ON". then i must sort these values so that it will be in acending order. Then i must write back that values in same text file after the line FMAT,2.. Now i can read the lines which contain T. Then i store that lines in array. My code shows error when i used sort methode to sort the array which i store in array.
This is my code
Dim filename As String = strFileName
Dim i As Long = 0
[CODE]...........
The sort methode give me this error "Overload resoulation failed because no accessible 'sort' can be called with these argument". Why it shows this error and how i write back the value after sort. Can i use append Text methde.

I'm writing an application for my Smartphone (OS is WM6 pro .NET Compact framework 3.5). Up till now i used VB6 so i'm pretty new to VB2008.
The application needs to store a set of items in a text file located on the device and retrieve them back. Since WM 6.0 doesn't support MS Access databases i have to work with the old fashion text files to store and retrieve my data. However since i'm new to VB2008 (and given the limitations of writing a smartphone application) I would llike to know how to write and read data to and from a text file.
