I'm using Silverlight 4 OOB & elevated trust.
I need to get all the filenames on specific directory & populate an object List(Of String)
The compiler throws an error "Method not found" on .Getfiles() method.
Dim files() As String = System.IO.Directory.Getfiles(Path) 'this line is failing..
I can't figure out how to use the (because im noob)ystem.io.directory.getfilesIf I try to put it in a textbox for example textbox1.text = system.io.directory.getfiles("my directory") then I just get the error message "Value type of '1-dimensional string of array' cannot be converted to 'string'. First of all I have no idea what the '1-dimensional string of array'thing is.And if I try to put in a msgbox for example sgbox(system.io.directory.getfiles("my directory")) then I can run the program but when I click my button then it says "it can not convert argument prompt to string(google translated)". And second, I don't know what the prompt thing is either
View 4 RepliesI am wondering if there is a simple method to filter the result returned by Directory.GetFiles(). Basically I am looking to retrive all of the jpg files in a selected folder into an array. My current code works fine if the folder only has jpgs in it which should be the case in operation but I would like to make sure it works correctly when the folder contains other types of files as well. The line I am currently using is..
Code:
files = Directory.GetFiles(IMAGE_DIRECTORY) files is defined as an array earlier in the program and as I mentioned my program works fine when the folder has nothing but jpegs within. The problem is that I am creating a listview with thumbnails from these files and run into some indexing issues when there are non jpgs in the target folder. The easiest solution would seem to be a filter on the getfiles method that would return only files witht he given extension.
Anyone know how to do this or will I need to parse the files out of the array in a second process?
i need to set more filters (or patterns) in:
vbcode
System.IO.Directory.GetFiles(path, "*.jpg")
i need to get not only jpg but more extension,how?
I'm trying to load the most recent file from a directory, but my following code doesn't work. Am i getting something obvious terribly wrong?!
Dim myFile = Directory.GetFiles("C:UsersJoeDesktopXML Logs").OrderByDescending(Function(f) f.LastWriteTime).First()
I get two error messages:
Data type(s) of the type parameter(s) in extension method 'Public Function OrderByDescending(Of TKey)(keySelector As System.Func(Of String, TKey)) As System.Linq.IOrderedEnumerable(Of String)' defined in 'System.Linq.Enumerable' cannot be inferred from these arguments. Specifying the data type(s) explicitly might correct this error.
And:
'LastWriteTime' is not a member of 'String'.
In the code below I got a UnauthorizedAccessException unhandled, access is denied to the directory
'c:WindowsSystem32LogFilesWMIRtBackup'.
A first chance exception of type
'System.UnauthorizedAccessException'

How can I make the search only in allowed access directory's???
Dim searchResults As String() = Directory.GetFiles("c:", "*.idw", SearchOption.AllDirectories)
For Each result As String In searchResults
MessageBox.Show(result)

This is the code I have set up to scan a directory of files:
Dim fileArray() As String
fileArray = Directory.GetFiles(System.AppDomain.CurrentDomain.BaseDirectory & "help")
And it successfully gets all files in the directory, but it gets their absolute paths as well. For example, one of the entries in fileArray() is:
F:ProjectProjectinx86Debughelpook_troubleshoot.html
And I want it to just be:
book_troubleshoot.html
Is there a way to do this without parsing through all the array entries to trim off the path?
When I have a directory setup with a subdirectory and both the top directory and sub directory have files in them I get a list of all the files with no directory info. That's OK, but I need to restore them to another location with the same directory structure in place. I'm essentially copying all files in a directory and it's subs to another location. The problem is the sub directory info is not in the files list so everything goes into the main directory. How do I get around this or can I? Here is what I'm using now.
I have a directory, NewProg in Program Files and a sub directory under it called Sub.
files=dir.getfiles("C:Program FilesNewProg",searchoption.alldirectories)
My.Computer.FileSystem.CopyFile("C:Program FilesNewProg" & File.Name, "C:NewProg" & File.Name,True)The Sub directory is not created and even when it is there, it always comes up empty with all it's files copied into the main NewProg.
I have a directory 'C:Test' with three files in it:
A23456789.txt
A1.txt
G 5.txt
And I run this command:
Dim FileArr = Directory.GetFiles("C:Test", "*1.txt", SearchOption.AllDirectories)
All three files are returned.I understand that this is by design and .NET searches the 8.3 short file names as well.But is there any way to override this and search the actual file names only?Surely, in this day and age there must be a function to do this. Or do I have to write my own?I would like the search function to have the same behavior as the Windows Explorer for consistency.
I am using Directory.Getfiles(DirPath,"Pattern")to locate specific files in a folder. This works fine unless no files are found. How can I get my code to determine whether no files have been found?
View 3 Repliesin this last weeks i've tried to discover how to use data usin' WPF's. So, in resume, i know how to use data in VB Windows Forms Application Projects, using SQL or Access Files connections.But in WPF and Silverlight i dont know how to bind database. In order to show, per example, data in a datagrid. Or in A Combo.
View 4 RepliesHow can I convert int to System.Windows.GridLength in VB, NET so that I can set the height of a grid row in Silverlight (xaml).
In xaml file:
<RowDefinition Height="0" x:Name="rowerror" />
In VB.NET:
rowerror.Height = CType(30, System.Windows.GridLength)
This as I wrote in VB.NET. I know I'm wrong, but how do you do if the int to System.Windows.GridLength so that the height of the "rowerror" whether that be 30?
I have a number of very useful extension methods that I'd like to use in my Silverlight project.I've pasted the Module here [URL]The problem I'm having is that visual studio complains that the dlls my module have been written against have not been built against the Silverlight runtime.Is there an easy way to get these extension methods working in Silverlight?I'm thinking my main hurdle is getting IObjectSet and ObjectContext to run against the Silverlight run-time - perhaps there's another way to expose these methods that I'm not aware of.

View 4 RepliesI have a LOB app written in VB.NET with a WinForms front-end and SQL back-end. After many months weighing up how to get onto the Web, I decided last month to use Silverlight 2. Now, Silverlight 3 Beta is out, but there is no end-user runtime.
Does anyone know when the runtime will be available for deployment of SL 3 apps onto client sites?
My dev timeline is about 3 months: should I persist with SL 2 and then u/g to SL3, or jump straight in to SL3?
I am having this line in two of my windows phone applications :
Dim doc = XDocument.Parse(e.Result)
in the one of these apps it is working fine , in the other one it seems wrong ...
actually it cant find the object "XDocument"
When i am typing :
Imports System.Xml.Linq
it send me bug a warning :
Warning 2 Namespace or type specified in the Imports 'System.Xml.Linq' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
the only diference between the application that works and the applications that sends me back this bug and this worning is that the one is a simple windows phone page (the working one) and the other one is a panorama page
i am having an error :"Attempt to access the method failed: System.IO.File.Exists(System.String)"
i have to note that this line is having an external url

during my first try it worked but now it seems bugy :S it does not make sense !
I am after the one which is most used. A number of ones I have come across are:

Application.StartupPath (this one doesn't work for me, missing a library?) I am using it to save a file, for argument sake, "test.txt"
I'm trying to emulate the possiblitys of what windows does to try and locate a find and I'm kind of stuck on 2. The current directory for the parent process. I'm guessing if you execute it from cmd.exe it would check c:windowssystem32 folder cause that would be the parent process and that is its folder, but if you double clicked, seems to set the working directory to the path where the exe is located.

I found the following example of how to print a root directory on the net
Code:
Sub Main()
Dim Current As String
Dim Root As String
Current = Directory.getCurrentDirectory()
Root = Directory.GetDirectoryRoot(Current)
Root = Directory.GetDirectoryRoot("")
Console.WriteLine("Current directory {0}", Current)
Console.WriteLine("Root directory {0}", Root)
End Sub
However it just causes the error "name directory not declared"
I had originally saved the project I was working on to my desktop, but now I have moved the folder to another location on my hard drive (didn't want it on my desktop anymore).
But since I've moved it I get the message:
The working directory does not exist: 'C:old folder locationResources'.
Is there a simple way to update my project to the new folder location?
when you start a new projekt, vs2010 makes a new folder for the projekt. when i reach a certain point in my projekt i want to save that version of the projekt.
what i do is make a new folder and copy that projekt to it. projektfolder2 . when i start the projekt in the new folder the sln doesnt work anymore. the vbproj works then. and vs 2010 makes a new sln file one directory down of the old one between the other
projekt files.
I am currently working on a project, which requires to download files from the internet and copy them to certain directory's... I've done the downloading part but I can't seem to get the directory working. The directory is "special" E.G. Appdata Program Files etc., and well when I tried just using %appdata% it seemed to create a new directory NAMED %appdata% rather than actually goto appdata...

I am working on a GUI for a simulation program. The simulation program is a single .exe which is driven by an input file (File.inp placed in the same directory). The Original.inp file functions as a template from which the form reads all the values into an array. Then it changes these values reflecting the changes done by the user in the form. After that it writes all the new values to File.inp. By pushing the "Run" button the Simulation.exe file is executed. The folder structure looks like this:
[Code]..
Ideally I would supply only the GUI, the user would select the working directory and then the GUI.exe would create an input folder and extract the Original.inp and Simulation.exe in the appropriate locations. So far I have only managed to include Original.inp and Simulation.exe as "EmbeddedResources" in my VB project and I have let my code create an input folder in the working directory chosen by the user.
how I can extract the .inp and .exe file into the correct directories? I've searched on google, tried File.WriteAllBytes and Filestream.WriteByte but did not get the desired results. The problem with File.WriteAllBytes was that I could not point to the embedded resource ("Simulation.exe is not a member of Resources" and with Filestream.WriteByte I got a 0 kb file.
I've got an application that has a bug right now, but we're unable to update the end-user to get the fix out. What a possible workaround would be is to change the working directory to the application's install directory, but from what I can tell, there's no way to do that outside of the program itself.
