Linq - Moving Ten Files At A Time Using .NET?
Feb 22, 2012
I as seeking to move 10 file every 10 minutes from one folder to another using .NET (vb c#) I am was thinking that i could of achieve this with LINQ query, but i cant get my head around this would there be a solution with LINQ or otherwise that can select the last 10 files form or top 10 files. so that i can move only these files from Directory1 ( the big pool of files) into director 2 ( a smaller more manageable pool of files).If all fails- then i wll manually have to copy or cut to at a time.

I'm just testing things and seeing if I can get things working and if I can then I want to try and develop this into something more. So far its just a simple button1 finds all files with extension of .mp3 in C: and displays all the findings in a listbox. I then want to use button2 to copy or move (I want to see how to do both) all of the files that are in that lisbox to a directory of my choosing. Here is what I have so far.
Imports System.IO
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As

I have been creating a program that copies and moves files from folder to folder; I am using this sort of code;
fileToCopy.CopyTo("path here...")
or
FileToMove.MoveTo("path here...")
My problem is, when I am copying or moving a large file, It's taking so much time and my program is hanging until all the files are completely moved or copied. How about, using a progressbar instead, so that the user will be able to see the progress of copying and moving instead of the program freezing?

I'm using an xsd file for a couple of my data sets that I'm using to read access databases. While this is great, I just got a new requirement that allows the user to change the link to the access database on their computer. Is there any way to allow them to set the path while still being able to use the xsd files, instead of doing it all through code?

I am making a program that takes files (inside their folders) and copies them into a selected file path. For example, I plug in my jump drive, run my program and it copies my files on the jump drive over to my PC. Now my program does this but it takes the files inside each folder in my jump drive instead of creating a folder for each one in my jump drive. The result is a mess of files in the selected pathway in my PC.I went and created variables in My.settings so that you can save the file path even after you close the program. I just want the program to copy the folders(with the files in each folder) in my jump drive and move them over to my PC.I am using this program copy the files from my jump drive over to my PC, because I save a lot of work on my jump drive and I need to back it up often.

I am having trouble opening my vb.net 2005 project from a backed up copy on a hard drive. The original files are on my old XP computer which I no longer have access to. I am trying to open the project in vb.net 2010 on Win7. I have converted the project to vb.net 2010 and when I open the file, nothing shows up, when I try to open them, it tells me the form isn't found in the project directory because it's been moved or deleted. I know that the software on the hard drive didn't back up .exe files, I'm not sure if it did back up other kinds of files. I don't want to restart the project because I've spent over a year on it and have written over 3000 lines of code on it.

I am creating a setup file using features brought by Visual Studio.I have some files which can't be removed from the application's folder. How to put the condition on it? or how to prevent user moves it after installation is done?Those files are critical (eg .dll).I already set the 'Hidden' property to 'true', but I think that is not the correct way :)So I try to find another way to do that.

I have a webserver and I upload files to my webserver from time to time. I have an ftp account which points to public_html that is main directory.
I though why give full access so I created another ftp account (e.g. test) which points to a specific folder. Now when I try to upload a file using test it fails.
For e.g.
the following code works:
My.Computer.Network.UploadFile("d:ok.txt", "ftp://mysite.com/Test/okay.txt", "main@mysite.com", "mainpw")
- this is because this a/c has access to root folder of website
now following code gives error -
My.Computer.Network.UploadFile("d:ok.txt", "ftp://mysite.com/Test/okay.txt", "test@mysite.com", "testpw")
The remote server returned an error: (550) File unavailable (e.g., file not found, no access).
Well the ftp account test has been given access to a specific folder with the name "Test". So it should at least upload to that folder.
But if I use ftp client (like filezilla) then it works.

I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.

I know that LINQ queries are deferred and only executed when the query is enumerated, but I'm having trouble figuring out exactly when that happens.Certainly in a For Each loop, the query would be enumerated.What's the rule of thumb to follow? I don't want to accidentally enumerate over my query twice if it's a huge result.
For example, does System.Linq.Enumerable.First enumerate over the whole query? I ask for performance reasons. I want to pass a LINQ result set to an ASP.NET MVC view, and I also want to pass the First element separately. Enumerating over the results twice would be painful.It would be great to turn on some kind of flag that alerts me each time a LINQ query is enumerated. That way I could catch scenarios when I accidentally enumerate twice.

I need to have a query which list all the user according to the date value in the database. Problems is this, in the database the date format is 5/5/2009 4:30:12 but I want to compare with 5/5/2009. I think the value of the based date is 5/5/2009 12:00:00 and that's why I couldn't query it.
The query is something like
dim db = new databcontext
dim user = from u in db.datacontext where u.signUpTime = 5/5/2009 select u.

I need help on how can I transfer a query from Access to LinQ that calculate the average in time per transaction during a given date.the working Access query is:
Avg(DateDiff("s",CVDate(Format([start_time],"hh:nn:ss")),CVDate(Format([finish_time],"hh:nn:ss")))) AS Expr1, Format([Expr1]3600,"00") & ":" & Format(([Expr1]60) Mod 60,"00") & ":" & Format([Expr1] Mod 60,"00") AS format
How can I port this to LinQ?

The following code works perfectly to allow moving a control on a form at run-time. However, when AutoScroll is set to True on Form1, and you drag Button1 past the right and/or bottom bounds of the form, it goes haywire. I really need someway to smoothing control the autoscroll so that as you scroll the control off the form, the scrollbars smoothly appear.

I have an untyped dataset returned from my WebService. The user wants to dynamically construct a query referencing tables and columns and specifying values to test for.I have looked at Lambda Expressions and the Expressions.Expression Namespace. I think these provide the answer I'm looking for, but I'm not certain how to go about contructing the linq expressions to extract the datarows I'm looking for.
I plan on limiting the result to one datatable that the query will result in and i"ll provide the joins from the user's constructs.For a simple example I have a DataTable with (n) rows called "Table", and in it there is a computed column called "b_IsActive" that has the expression "Convert(IsActive, 'System.Boolean')". The user wants to retrieve all rows in "Table" where field "b_IsActive" is true.

This seems to work, and even when I debug VisualStudio says that the file changed, but actually it doesn't. I think the problem is in the Save() action, but I don't know other way to save it...

I am trying to read information from a text file(.txt) using LINQ.I can't use a list box of predefined continents that someone can click on and it will bring up data from that continent.It will work if I let the countries fill the list box from the text file but then if I have two people from England my list box will display England more than once.For example my UN.txt file that is in my debug folder: [code] So I guess I have two different questions: 1. Is there anyway to stop the duplication of the continents as shown above? Can I pre-fill the list box with the continents and not have to fill it from what's in the data file?

I am building help files for a program using HTML Help Workshop.I have been trying to manually add files to the project file list as I write them, as HHW doesn't do so automatically.But it doesn't seem to matter whether the files are included in the list or not.When I compile, it tells me if any are duplicated, but it doesn't tell me if any are missing.(I have deliberately removed some to see if it makes a difference, so it's not that I haven't left any out.) And, whether they are in the list or not, the compiled help seems to find the files it needs.What is this list of files for?What files need to be included in it - html, css, images, maps? Why doesn't it seem to matter if my files are included in it or not? Is there any way to add files to the list other than one at a time? (e.g specify an entire folder?
