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.
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 have several textboxes trough which i add data in the database. after clicking the save button the data is added to teh database. and if i click again on the ssave button without changing the content of the texbox it adds the same data to the database. i have tryied using textbox.modified but it only works for blank textboxes. how could i prevent from adding the same data?
I've downloaded an MD5 tool to calculate the MD5 string of my app.exe e.g. (e.g. MD5 string = 0b7ee747f3be5bc53b8afd4f01b5c22a).I was just wondering how i could put the calculated string in startup of my app to see if it has been modified
I have a list of users with me and I need to find out programmatically which of the users present in the list have read/write permissions on a particular folder/file.
How can I check if an Image File exists in a Folder?I need something similar to this:If C:***My RecipesNick's Milktart 237.png Exist ThenThe code that goes here is not a problem; I will show it as soon as it works.
I want to save a bitmap object to file, but I want to make sure the file path is writeable first. The user should have write permissions to the folder and it should not be a location on a CD drive.Right now, it gives a "A generic error occurred in GDI+", which is not too helpful. I'd rather tell the user that the selected save location is not writeable.
Actually i have to update a software daily on 20 computer and connecting to internet kill my ADSL connection. i would like to download the file on my server and then schedule a task to pick it up from the server share folder.how i can write this script and then put it on the 20 computer so that it come to check the folder on the server then update to the latest file?
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 am trying to read this XML document. An excerpt: <datafile xmlns:xs="[URL]" xmlns:xsi="[URL]" xsi:noNamespaceSchemaLocation="wiitdb.xsd"> <WiiTDB version="20100217113738" games="2368"/> <game name=" Wanted: 50 Wacky Jobs (DEMO) (USA) (EN)"> <id>DHKE18</id><type/> <region>NTSC-U</region> [Code] ..... It just skips the "While iter.MoveNext" part of the code. I tries it with a simple XML file, and it works fine.
i am trying to get files name, modified date in a folder Before i get those files, can i pump a command by using vb to the folder and make them sort by modified date?
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.
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?
I'm writing a .txt file which is loaded using the following code. When running a Debug I get a message on closing the .txt file saying 'This file has been modified outside the source editor. Do you want to reload it?' Is this juszt a nag screen for the editor, or will I get an error from the final compiled .exe program build?
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?
I was able to do this all successfully in VBA, but just couldn't convert it to work in VS 2008. 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.
I'm making a sort of like platform for archive editing.This includes opening archives, displaying content, extract files, edit files, place files back in the archives.My problem is, that I can't trigger the program to replace a file to the archives as soon it is modified.I did think of making a thread, checking all file modified dates, but since it regards over 100 files it lags. So that is no option
How do i can make application check Last Modified time from file via FTP.And check out which is your folder's last modified time.If FTP File Modified Time is latest than your file'sfolder then WC.DownloadFile(FilePath/File)
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)
[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 am writing a program to automatically recognize new data log files in a specific folder and proceed to process them in a routine I scripted. 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?
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?
Is there a better (and faster) way to find out the last modified date/time for an entire drive (or folder) without scanning each file and folder individually to find the latest modified date?
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.
