I have a files list which contain the directory of file. I want to know file creation date of that files. I used fileInof.CreationTime. But It is not displayed creation date. How I can know about this.
[Code]...
I'm trying to save a files save date, modify that file and then restore the file back to it's original date. I can't get it to work, I've tried it several ways and cannot get it to work.
My code so far is
origdate = My.Computer.FileSystem.GetFileInfo("inspection").L astWriteTime.ToShortDateString()
' changing file content here
System.IO.File.SetLastAccessTime("inspection", origdate)
be able to check if an application i am writing has been run on a week by week basis. i have created a button that when pressed creates a text file with nothing in it, i can read back the date it was created which also gives me the time which i dont need, i then need to compare the date the file was created to see if it is older than 6 days if so delete the file. how can i check to see if a creation date is older than six days???
View 9 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 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....
View 6 RepliesWhat is the easiest way to automatically fill a datetime column in an SQL data table with the date the row was created? Using SQL Server 2005 if that matters.
EDIT: I've tried using GETDATE() for default and that works for an INSERT Query but not when the TableAdapter adds the row.
I'm trying to pull the creation date of all the files (1000+) in a folder on a local server to list in an excel file. I've been trying to use FileSystemInfo for this, but it doesn't seem to work to get the creation date of MULTIPLE files because it doesn't allow me to use wildcard characters to read all (not even sure if that's what I'll need to do).
View 1 RepliesI would like to implement into my program a version query of the executable and I figured the easiest way would be having a check on the date of the executable.

View 10 RepliesI've written a loading program that writes text files to our database. The text files are dumped by another system every 2 hours onto on a shared network drive at my work. Here's the problem though - the files don't have a date/time stamp within them. I've been getting the date for each file from the creation date. That works okay, but when I've written loading programs in the past, I like to move the loaded files into a folder called "Loaded Files". That way, I can quickly see visually how many files I've loaded vs how many have not be loaded.
The problem this time, is that if I were to move the file into another folder, the creation date changes...a lesson I learned when I copied all of the files into a directory on my C: for testing. They all had the same date/time stamp!My question is, what's the best way to handle this? I don't want to move the files after loading them if it alters their creation date. I mean, what if I have to go back and load one for some reason, the date will be lost forever. I also don't want to write something into the software that has to check a file each time before loading it to the database.
I need some help in the creation of a program to generate a security code based on the current date. I need to create something that first multiplies the MMDDYY (ie X=MM * DD * YY) then also adds the MMDDYY then finds the remainder and then multiplies but a specified number. I would like to create a small program that sits in the system tray with this code displayed. The code will always need to be 6 characters, so I might need to pad it with zeros. It has been years since I took basic VB, and I am really rusty.

View 1 RepliesI'm trying to make my application append to a simple log file when it executed and when it's closed. So far, so good (see code)
However, what I would like to do, is have future lines of text to be written on the next line instead of the same line. And possibly a date stamp.
I'm not quite sure how to implement this as far as syntax goes.
My.Computer.FileSystem.WriteAllText("C:log.txt", "Application was closed ", True)
How can I check for characters not allowed for file creation programmatically? you know like the / <> and so.

I'm trying to compare the modify date of a file vs the current system date. I've found an MSDN article describing how to get the modify time of a file:
Dim infoReader As System.IO.FileInfo

MsgBox("File was last modified on " & infoReader.LastWriteTime)
This gest the Date and Time, but I want just the Date not the time.

View 20 RepliesI 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
lstvehicles.Items.RemoveAt(lstvehicles.SelectedIndex)

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.
