Well I basically know how to read a text file, replace text then write to one. how to append text after a specified string (ie, insert text at a specified line, removing the text after a string in a line and changing it without altering other lines, etc). Can someone please tell me how I would go about adding a string after a certain string in a text file? For example:

i have a string array that i want to output to a text file. the array size is 10000. i fill the array starting from 0 with some strings. at the end, i only want to show the array from index 256 to the last array that is not empty (for eg. if the array is filled with data from 0 to 2000, i only want the text file to show the data from 256 to 2000 and ignore the remaining strings). Is there any function to do this?t i use is shown below
Dim myArray(10000) as string
Dim strArray As New System.IO.StreamWriter("c:List.txt")
strArray.WriteLine("{0,10}{1,30}", "Index", "Symbol")

I'm trying to make a program that can export my schedule into a CSV file to upload on to google calender.I need to extract some text within a textbox control. I'll show you an example.This is the text in the textbox:
Quote:
Monday, 10 January, 2011
09:45 - 18:00
Phone Work09:45 - 12:15
[code]....
I need to get just the date and times from this list, and put them in variables. so that I'll end up with:
1) A string with a value as a date, which would be "10 January, 2011" for example: strDate1 would have the value of "10 January, 2011"
2) A start time, for example: strStartTime1 would have the value of 9:45
3) An end time, for example strEndTime1 would have the value of 18:00
I have a binary file. If I look at it with a hex editor, the first values are:208, 207, 17, 224, 161, 177, 26, 225, 0, 0, 0, ... etc.It has a length of 330240 bytes I have tried to open it and read it into a string so I can manipulate it and write it back. No matter what I use, I either don't get the correct number of bytes or the values in the string are incorrect. The most common error results in the first values being: 63, 63, 17, 63, 63, 26, 0, 0, 0 .... etc.It is interesting that it appears that any value > 63 becomes 63.
I get the 2nd values by a simple loop:
For lnx = 0 To 99
Debug.Write(Asc(line.Substring(lnx, 1)))
Next
I have tried a whole number of ways to read in the file, including filestream, My.Computer.FileSystem.ReadAllText, File.io.readAllLines, etc.All either give me a string length of about 324000 (not sure why) or, if they do, don't have the correct values. Yes, I have tried various encoding options.
I need to find a string (sort of like: "D" & Chr(0) + "L" & Chr(0) + "S" & Chr(0)... ) so I can then replace that portion of the string with a new value, then write out the file.I use the ".indexOf" to find the data in the string.Why can't I load the file into a string? Or, do you know of an easy way to find some text (similar to above) in a file and then replace the next x number of bytes with a new value and close the file?

The program works fine except that I am having problems in returning the page numbers of the matched string.
The page number value is always returned as one.
The following is a piece of what I had written:
If FindStringInFile(wordfilename, vValues) Then

TextBox3.Text = currentPageNumber

All I am doing is reading each txt file I find in a directory and finding certain strings in the text then counting how many I find in each file and then once each file has its separate counts it send it to a sql database. I have most of it done, but I cant seem to get the count to separate each file so my problem now is that it counts the first file but when it counts the next file it adds to the first file and so on through all the files

View 6 RepliesI have to find a string in a huge text file ( ~ 50MB) and then replace it.Since it's quite huge I tend to open the file and then read line by line, and then replace the necessary line(s) (rather than "readall" the file of course).My question is how to replace the whole line?Let's say I found the line that should be replaced . I know I can create a copy file and copy all lines into there ... but I'd prefer to replace the line in the original file rather than creating a copy instance.
