I'm having a little trouble trying figure out a way to filter specific file formats to only show in a Listview. For example I only want .txt files to show in a Listview and no other file formats. Is this achievable?I've had a look around the net but not found anything relevant to what I am trying to achieve.
I want to filter data on the textchange event on listview so I use dataview to filter data. Issue in the below code is, I use dataview inside for each so that it checks only one condition that is last value only it takes, I want to check value in s1 with dataview and remaining value should bind with listview. E.g.: if I type an in textbox it should list all the item values starting with an value like anandha kumar, anna etc. Suppose I keep the value anandha kumar and anna in array s1. I should list all other values expect the array values like antony etc... in listview.
I have a WPF ListView that I am trying to filter within a BackgroundWorker. My code is shown below:
Dim Worker As New BackgroundWorker AddHandler Worker.DoWork, AddressOf Me.FilterAsync Me.TextBoxText = Me.TextBox.Text Worker.RunWorkerAsync(Me.TextBox)
[code]....
This code runs through the filtering however it fails with an error "The calling thread cannot access this object because a different thread owns it." on the following line:
ListView.Filter = New Predicate(Of Object)(AddressOf Me.FindItemsAsync)
What would be the problem here? I can't seem to find any samples with filtering through the BackgroundWorker.
This is my line of codes. but it only compares to the equal match on the textbox. is there any way where i can match even just a keyword and will select all items with the same keyword that i type on textbox.[code]...
I have a listview and a textbox under it. Whenever a user input's text, I want the listview to filter. The code I have works, but the listview doesn't load the filtered data. I think it's because the listview has 2 columns of data that it's loading. [Code]

I am populating a datagrid control using files in a specified path (DirectoryInfo).I would like to filter the files based on a user specified date range (start date & end date). While search S/O, I found this post, but I am getting an error on DateComparer ("'DateComparer' is a type and cannot be used as an expression.")
Here is my code:
Dim dirInfo As New DirectoryInfo(strDirectoryPath) Dim dStartDate As DateTime = "03/01/2011" Dim dEndDate As DateTime = "6/30/2011"
I need to write a process which filters out 'old/dead' job files from a directory (actually two directories). This process needs to 'read' a number pattern (in a fixed position) off the filenames (for which there will almost certainly be duplicates), and having then 'got a list' of unique number patterns, give these to a function (which I already have) which will give a boolean, from which I can decide to either delete those files whose name contain this particular number pattern or not - this is intended to be run each night (windows task scheduler). Example directory content is:

The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.

I'm trying to figure out how to list all files of an FTP folder in a listview but I can't figure out how to do this. I tried using the same approach as if I were to list contents of a folder in my harddrive. But this fails.

[Code]...
But I'm not sure what I'm doing during the "For Each" loop.

I'm trying to figure out how to make the code from HTML url...I have in a listview with some pdf filenames..each of these pdf's have bookmarks to other pdf files.I managed to get the code to export the bookmarks and load them into the listview..but only the first listing seems to be working. when it gets to the second listing,, when it gets to the exportbookmarkstoxml function..it hits the catch from then on..i've tried several different things and none of them seem to be working..the code i have is somewhat messy because i been messin' with it,,but i'll try and tidy up as much as possible for ya.I'm thinking that something between the using statement needs to be closed or something but i can't get it to come even close..i even tried closing the reader with reader.close and then deleting the outputxml and then making the file again but that isn't working either.
