Reconcile A List Of Files And A Directory With Subfolders/files To Find Changes?
Jun 3, 2010I have a SQL Server table with a list of files (path + filename), and a folder with multiple layers and files in each layer. I'm looking for a way to reconcile the two without having to process the list twice. Currently, I'm doing this:
For Each f as FileInfo In FileListFromDatabase
If f.Exists is False, mark it as deleted in the database
Next
[Code]....
Is there a better way to do this? I'd like to avoid converting all the matching files (of which most will be) to FileInfo objects twice. Since I'm a T-SQL developer first, I'm picturing something like an OUTER JOIN of the two lists where they don't match. Something LINQ-ish?

2d Array Of Strings And Nested For Each Loops?

If I change the outer loop to:
For Each str() As String In newdata
It builds ok but I don't get what I want. The outer loop process the elements of newdata as a 1d array and the inner loop sees each character of the strings from the outer loop.So...is there a way to use the for each structure and process a 2d string array? If so, what should I change? If not, what is the best alternative?
Forms ::List Files Without Matching .pdf In Same Directory
Apr 28, 2011I have an 'In' folder that users drop all different types of files into (.doc, .xls, .rtf, .pdf etc.).Each file that gets dropped into the 'In' folder should have a matching .pdf file (i.e. abc123.doc and abc123.pdf)I have a program which looks into this 'In' directory at regular intervals and moves filename.* to another directory. The folder the files get moved to depends on the first 2 characters of the filename (12-abc.doc might get copied to folder '12' etc).All the files placed in the 'In' folder should have both a native file and a matching .pdf i.e. (abc123.doc and abc123.pdf)In some cases the native file is missing. In some cases the .pdf is missing.There are 2 things that I want to do.
1.) I want to prevent files being moved from the 'In' folder if a .pdf does not exist (I think I can deal with this one ok).
I think perhaps a For Next Loop Array for filenames minus the file extension and if it already exists in the array then copy them (but what if someone has got a .doc and a .xls but no .pdf?!?!? I'm sure somebody could tell me a simple way of achieving this.
2.) This is the part I am struggling with. I need to look in existing folders that files have already been copied to and list:
a.) Native file without matching .pdf
b.) .pdf without matching native file
c.) .pdf with matching native file
User To Select A Directory And Then List The Appropriate Files?
May 6, 2012I am using the following code to allow the user to select a directory and then list the appropriate files within that directory in a combobox. What I would like to do is sort that combobox into a descending order so the most resent files are listed first as the filename contains a date yymmdd.

If FolderBrowserDialog1.ShowDialog() = DialogResult.OK Then
TextBox1.Text = FolderBrowserDialog1.SelectedPath

View 1 RepliesPrepend A String To All Strings In A List Of Strings?
Aug 5, 2010I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))

It works, but I would rather use built in functions whenever possible.
VS 2008 Using List Of Strings Or Array Of Strings?
Oct 16, 2009I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?

Apr 8, 2011I am going to need to create a windows form for work that we can connect to a database table, select a directory and move files from the directory that are in the table and move to another folder. The directory will have sub directories that I need to search for the file name and move. I would like to have the table hold the file name (or path) and move all files that are in the database. There might be 20 files or 1000. Depends on the client we are processing for.

Reading Text File In Directory And Finding Certain Strings

I have most of it done, but I cant seem to get the count to separate each file so my problem now is that it counts the first file but when it counts the next file it adds to the first file and so on through all the files

View 2 RepliesC# - Getting Hash Of A List Of Strings?
Mar 21, 2009I would like to write a function GetHashCodeOfList() which returns a hashcode of a list of strings regardless of order. Given 2 lists with the same strings should return the same hashcode.
ArrayList list1 = new ArrayList()
list1.Add("String1");
list1.Add("String2");
[Code].....
I can first sort the list, then combine the sorted list into 1 long string and then call GetHashCode(). However sorting is a slow operation. I can get the hash of each individual string (by calling string.GetHashCode()) in the list, then multiplying all hashes and calling Mod UInt32.MaxValue. For Example: "String1".GetHashCode() * "String2".GetHashCode * ... MOD UInt32.MaxValue. But this results in a number overflow.
