.net - Get File Modified Date

Sep 8, 2010

I have a number of files in a folder, I need to get the last modified date. So I used FDate = IO.File.GetLastWriteTime(FName) Works fine with some files, but on others, I get a date of 1/1/1601. But when I check the files in Windows Explorer, all the dates look normal (recent). So, I'm gessing there are multiple files dates stored in the file system, and the ones dotnet is seeing are not the ones windows is seeing. How can I get exactly the date which appears as "date modified" in a file explorer window? I tried some vb6 api stuff but that doesn't seem to work in dotnet.

Retrieving File Modified Date?

Apr 5, 2009

I'm using VB.net 2003 Standard Edition, and I'm trying to retrieve the file modified date. I've created a System.IO.FileInfo object, and have collected info from the three methods: CreationTime, LastAccessTime, and LastWriteTime, but they aren't giving me the same data as XP Windows Explorer is.In Explorer, there is a Date Modified field (currently reading 2008 on the file in question), but using the FileInfo methods they return 2007, 2009, 2009.Is there another IO object I can use to get this 'modified' date?

File Creation/modified Date/times?

Mar 16, 2010

I created a background thread that constantly scans a specified folder for any .xls files that are created or modified. These files come from a vba macro in outlook that will automatically save the attachments of the mails in the this folder. This will update the modified date/time, or at least it seems to.

For Each fi In aryFi
fidate = System.IO.File.GetLastWriteTime(path & fi.ToString)
fidate1 = System.IO.File.GetCreationTime(path & fi.ToString)


Everytime I check to the code, the fidate and fidate1 variables are indeed the correct dates/times of the file it's currently checking. It almost never gets inside the elseif block at runtime though.

.net - Sort Datatable / Dataview / Gridview Of Files Based On File Modified Date

Aug 2, 2010

I have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview. I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows). If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that.

Get Modified Date Variable In SSIS?

Mar 7, 2011

I am trying to pull the modified date of one file in a folder through a SSIS script. I tried doing this through the system.IO namespace as it contains the GetFileName method. This isn't working & I was wondering if there was a name space that contained the modified date method for a file if I specified the path to the filename. I am looking to return the modified date variable in whichever way this may be possible.

Check If A File Is Modified?

Jan 15, 2009


-folder x resides on server a, server b ,server c

-x contains same set of files in a,b,c

whenever any file gets modified in a, it should get also modified in b and c as well

similarly b->a,c and c->a,b

my idea of implementation is -when ever any file is modified on a server, compare timestamps and force copy the modified in the other two How should i go for implementing it?

1)how to check if a file is modified

2)how often this check should be done and how this should be implemented should a service be running to perform thi check i want to do this using .NET?

Basically I'm in search for a script that Loops the following 3 processes, I also need it to run from an .exe file or similar with no UI (User Interface) so it constantly runs in the background (This is all to go with a multimedia software):

if file 'c:X.txt' has been modified equal to or more than 15 minutes ago, then send key R.
if file 'c:X.txt' has been modified equal to less than 5 minutes ago, then turn on numlock light, if not then turn off light.
if file 'c:X.txt' has been not been modified for the last 4 hours, then send key delete file.

Check Folder For Modified File Quickly?

Oct 10, 2011

I have a folder that can (hundreds currently) but upwards of 10's of thousands of files. I have a program that gets all file names, and sorts them based upon set criteria and displays them in a treeview. My issue is right now a few hundred files moves fairly quickly when getting files name (path.getfiles), sorting, and returning sorted list for further search and display. My concern is when the number of files starts to increase, alot of these functions will take exponentially longer to perform. Especially my organizing function.

Because my files are part numbers <PartNum><Rev><SubRev><ManuNum>.<extension> I first sort out all different Part numbers first making the list manageable (maximum of a few thousand). Then as you choose a part number to work with, it retrieves all files associated with that part number (maximum of a few hundred).

My concern is everytime I need to look for a file in anyone of those steps, I have to import all file names, search and return correct file path, and Im sure this will become slow as the number of files increase. I dont mind having it do it once then update the list as needed. So I was thinking import and sort all file names at load, and check every so often for and files that might have been modified recently and just update it's entry in the sorted list. But this means my program has to stop, and check all files for changed "modified" time, which too will be slow-ish.

I have the program working fine for when I manually place files in there, but I know there will be an issue when my data logger is working because it will create files and then write to them for approximately 12 hours.[code]Which works fine, but how can I modify that or what should I use to force the program to wait until the file is done being modified? Say force it to wait at least 1 minute after the last modification?

Deleting Records From A LstBox And Dat File And Setting Reminders To Date In Dat File

Aug 2, 2010

I am creating a program that allows a person to enter details about their farm, stock, and machinery in order to electronically keep track of all of the information. I have created the forms and done all the coding for the data entry, and now what I would like to do is allow the user to delete a single record from the .dat file. I am able to delete it from the LstBox (using a "Delete Entry" btn coded simply with


(using the vehicles section for examples)), but I am unsure of how to delete it from the .dat file as well, to prevent it reloading upon data change / program reload. Also I would like to be able to have a reminder come up on the program start up that gives a reminder to (in the vehicles instance)when a vehicles rego is due, the date being associated to a date that is entered into the same lstbox data using a datetimepicker.

File I/O And Registry :: FileStream File Creation With Date?

Apr 16, 2009

I have found many pages referring to having the date be part of a txt file being created, but not like the way I need. Having said that, this is what I've got.. [code] I read a page on working with txt files and learned what I could from it. It said to use the method in the beginning of my code for creating the file. It works great, but I would like to have a new file name everday, hence the date being integrated. So even if program was running, when midnight hits, a new txt file is created and new entries are written to that file. But I can't even get the date to be put in there. Everytime I try to make this work by using methods I read about in other pages, I get a syntax error, or a warning saying an end of statement is expected. I'm not sure those methods are compatible with what I've already got going.I was actually trying to store these values in a database, and I got real close I think, but I couldn't get any help to fix my problem so I'm trying to write to daily txt files instead. url....
