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
View 4 RepliesI 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 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 Repliesscenario:
-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?

I 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?

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 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)

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?

View 1 RepliesI have some code that does a Find & Replace in some text files, and closes the file when complete.However, when I try to use the Kill command in VB to cleanup these files (they are temporary files) when the program is closed, I get errors that the file is in use by another app or process.Is there a way I can force these files to close first? This also happens when I scan a document using the EZTWAIN.dll Scan to native function.Everything goes fine, but if I try to scan again to overwrite the file, the file is in use.This is happening on Windows Vista SP1.
View 10 RepliesI have two tables "Person" and "Alias" in a one to many relationship. I have a DGV for "Person" and want to use a combobox for the Aliases. I also have a textbox and a button for the user to type the alias name and click the button to add the alias name to the combobox and update the dataset. I keep getting the "Items collection cannot be modified when the DataSource property is set." Error. But if i use a DGV instead of a combobox for aliases, I have no errors and everything works fine. If I remove the datasource property for the combobox it will not get populated with the data already entered, so how, or can I, set it up where the combobox gets populated when the form loads and able to add items to the combobox????
View 1 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.

In VB6 we had a code inside textBox_MouseUp to call textBox_KeyUp(-1, 0) and the signature of KeyUp was
Private Sub textBox_KeyUp(ByRef KeyCode As Short, ByRef Shift As Short) Handles textBox.KeyUp

I have created a simple framework for a Windows service in VB.NET Express 2008. It enables a timer which then writes to the event log every 6 seconds until the service is stopped. This works fine. I adapted that framework into something further. It is using Windows sockets. Well, I haven't finished that part yet and I just want it to write to the event log successfully but I can't even get it to do that now. I am trying to write an event in the OnStart event. The service is being started successfully, according to the standard event log, but my custom events are not getting there. I don't understand why as I am using the same code for that as I was before.
