how can i determine the file size and the date it was last modified..
i need to compare two files and determine which one is the latest and which one is bigger in file size..
compare a.xml to b.xml..
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.
View 2 RepliesI want to open a file from a folder by using the date modified properties in a file.
View 2 RepliesI'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?
View 1 RepliesI 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)
[code]....
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.
I have an ftp routine which gets various files from a server and puts them on a client PC.My problem is it loses the original Last Modified Date on the client PC. I can get the last datetime modified from the server but don't know how to assign this to the file on the client PC. Is there away to alter the last modified datetime?
View 3 RepliesI'm working on a project and need to determine the size of a text file. I know that I could just count characters but the file will be several MB's large.
View 1 RepliesSo we're having this problem. A user goes to upload a file, and if it's above 10MB, it just kind of times out the page, and clears, and no good error is thrown to describe what happened. Ideally, we would like to examine the file size when the user chooses the file they want to upload but I don't know if this is even possible. Our framework is built with ASP.NET, VB.NET, and Javascript (and ExtJS 3.0), and it runs in IE.
View 6 RepliesI 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.

When scanning a data file of this kind of form:
21/02/11 11:00:23, true, false
22/02/11 02:03:43 AM, true, false
22/03/11, false, false
2011-05-21T12:30:20, true, true
The 2nd and 3rd row are not important. How can you, by scanning a file, determine if a row comprises of dates, particularly when they have inconsistent formats? In the example above, for instance:
1) 1st line is date and time
2) 2nd line is date and time but also AM/PM
3) 3rd line is only date
4) 4th line is GMT format.
I'm not requesting code, but perhaps an algorithm or some guidelines on how to achieve this.
how I can display the date a file was last modified on a web form. I'm working in C#. I was able to do this in classic ASP with the following code, which I had in an include file:
dim bs, b
set bs=Server.CreateObject("Scripting.FileSystemObject")
set b=bs.GetFile(Server.MapPath("/directory/schedule.asp"))

I am using this to loop through a directory and grab the last modified date for all of the files. How I do find the last or most recent modified date?

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.

what is the size of the object oA?and what if Class A and B contain methods?(I meant the size of object)what if inherited class B contains overridden methods?(size of object)what if inherited class B contains variables with same name as in Class A?(size of object)I need theoretical answer.

I have found a user can change icon display size using 'control panel' > 'appearance and personalization' >'Display' where they can select small, medium or large. The result, even though the icon heigth & width values are not changed, the apparent icon size on the desktop(and also text size in controls) is changed. Hence, if the user has chosen a larger icon size that I have on my machine, text in a button is larger and may not be completely visible.Knowing the user font size choice, I could adjust font size as required.[code]...
I'm trying to find the sum of all the digits that make up the number 2^1000, which you may have guessed is from Project Eula. I think it's good so far except I'm just learning about arrays and dynamic arrays, so how will I know what the size of the index will be so I can specify when the Do loop should stop so I don't get an indexoutofrange exception?

I have a lot of files in the folder. I really want to "sync" the folder.

View 4 RepliesI have a form where a user can choose an election date. One of the most frequent errors users make is entering the incorrect due dates of reports. Therefore, I am attempting to generate the report due dates in the application using the report guidelines. For instance, reports are due 32 and 15 days prior to the election and 30 and 60 days after an election.
I know the following won't work but you get the jest of what I am attempting to do. I am assuming I will need to break down the month, day and year somehow before I subtract or add the days to the date to get the actual report date.

View 4 RepliesI have a "ClickOnce" application and on the Splash screen I display the Version. I am also displaying the "CreationTime" (see below) that I thought was when the Build or Publish was done. Today I realized it is displaying the date/time when the application is actually installed on the PC. How do I pull the date when the this version was compiled, Built, or Published? I really do not care which -I just want a constant date the sticks with that version. I'm using VB 2005.

scenario:
-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?
I am working on a vb.net project which is concern about the computer file forensic. Thing is i wish know is there any idea how do we know a file was modified and which part of the content was modified. For example, a file was consist of number of bytes which could be translate in string with HexEditor (* FF D8 00 EF.....). If someone was modified certain hex number from the file like (* 00 00 00 EF....)How do we know those hex numbers was modified? Any .NET class function can peform the action like that? Or is there any idea to do that?
