Search All Textfiles In A Folder And Write Last 10 Lines To A New File
Jul 1, 2010
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.
the first problem is getting my program to load rss feeds from other websites mostly here:http:[url..... im trying to load it using the webbrowser. i want the rss feed to load right onto the form. im positive that its possible. i have the imports system.net in my code already for xml documents.the second is i cant get my program to write into a file that is several folder deeper into the bin folder.[code]......
ive tried playing with the code moving around the folder names, making sure there capitals are correct, etc. but nothing works. it creates the file in the wrong spot.
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 got this erro after deployment of vb.net project of hospital management-- Error3Could not write lines to file "obj\hospital management.vbproj.FileList.txt".

I was hoping someone could assist with the following coding; I am trying to search a very large csv file (approx 200,000 lines) for a user defined string eg "0100020789" and I essentially want to print all the lines that contain this to a text box on screen. Please not that the csv file does not have standardised column headings, each line is different. There would be approx 5 lines that contain the input string.
I am concerned with the v large csv i am using which will prob slow everything down, but then I thought if simple text pad application can search for a string in complete files with similar sizes like that and return a result in less than 1second, then it must be do-able.
I have a folder that contains .txt, .pdf, etc files.I want to check if the folder contains a .txt file.If yes, I have to perform some action, if no, no action will be performed.I have this sample code to do the above, but with the know .txt file name.
Private Function DetermineIfFileExists() As Integer Dim sFileName As String sFileName = "C:/text1.txt" [code]....
In my case, I will not know the exact file name of the .txt file.I need to search for a .txt file.
How can I Search for a Image File in a spesific Folder. I need the code to be able to find an Image File by searching for an string in the Image File's name.

I'm doing a uni assignment and my application has to go to a specific folder and locate a file for data.The folder has 300+ files in it with a specific format for the naming of the files ie. the program goes to the folder looking for one specific file that has been derived from a different function and user input in the form.The program works fine when the file that it is searching for is there, but I keep getting a FileNotFoundException whenever the file that it's looking for is not there.I don't want the application to throw an exception every time the file doesn't exist because the program needs to return back to the loop to see if the next file is there or not.And so the loop continues until it's found all data and loaded it all into an array.How can I do a check of the folder to search for the file, and if it's not there, go to the next step without throwing an exception?
I'm using VB.NET 2005 Pro to write a batch file to empty folder contents, but I'm having problems putting quotations around the parameters.Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTNFCleanup.Click Create an instance of StreamWriter to write text to a file.
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 can't find how to search for a folder (directory) that contains a string and copy all the folders (directory) that contain that string to another directory. So you search for the name of the directory, not the files in the directory.For example: 'KTNPRK' in E: gives:E:KTNPRK1, E:AZNKTNPR76, etc...
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..

[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.
