I have an application written using VB.Net, framework 3.5.In the application I read LastWriteTime and CreationTime values for a file saved in file system. In general,the code works fine except one case when the application is started using Citrix environment. In this case the returned value for bithproperties is January 1, 1601.

The problem is that for some columns it sets the data type to be Double even though the spreadsheet column format is "Text" and teh column contains non-numeric data. Then when it gets to that cell it returns DBNull instead of the text value.
I have the following VB function which takes a FileInfo object as a parameter:
Public Shared Shadows Sub Start(ByVal filePath As FieldInfo)
XmlConfigurator.ConfigureAndWatch(New System.IO.FileInfo(filePath.ToString()))

In another class I have the following code calling that 'Start' method. But VisStudio indicates there is a problem with the 'FilePath' argument that I'm passing.

When I look at a file on the server, Windows 7 explorer reports a Date Created date of 5/20/2010 10:49 AM, and a Date Modified date of 5/20/2010 10:50 AM. This is what I expect and what I believe to be true.
However, running my VB.NET code, when I do My.Computer.FileSystem.GetFileInfo(filespec).CreateTime, that value is something completely different: 12/31/1600 6:00:00 PM, and My.Computer.FileSystem.GetFileInfo(filespec).LastWriteTime is set to that same value (12/31/1600 6:00:00 PM).What am I doing wrong? I need to get the values associated with "Date Created" and "Date Modified" as displayed in Windows Explorer.
The solution was simple, I used LastWriteTime instead of CreationTime CreationTime will = time that file was placed on that drive LatWriteTime will = Last time that file was written too, thus the actual original creation time (unless file has been modified of course, which in my case [wmv files] is not going to happen)
View 1 RepliesI have a simple (ASP.NET) web page that lists files of a particular type in a folder and renders them in a ListView.
I've tried to sort them by descending LastWriteTime, that is, in reverse date order. However, although the sort process does change the order of the array, it doesn't sort it correctly. For example, one item with a LastWriteTime of #6/3/2011 12:00:00 is top of the list, but another item with a LastWriteTime of #12/16/2011 12:00:00 is halfway down the list after sorting.

Dim dirInfo As New DirectoryInfo(Server.MapPath(AppSettings.Item("ContentDir")))

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

View 1 RepliesI developed a very simple little windows program in VB 2005 to be used on desktops here at HQ. It reads a table from an Oracle DB into an array, let's the user select a text file, and then uses that data and text file to create an Excel spreadsheet.
Now they want a remote user to have access to it. We use Citrix for our remote application access. There is no install, I just copy the code to the Citrix server so I didn't need to put terminal server in install mode. When I am on the Citrix server, the application runs well. When I access the application through Citrix, I get an Oracle error from the ODBC data manager: Data source name not found and no default driver specified.
Does anybody know what is going on? how to make it work?
Are there any papers related to Windows applications on Citrix server that can help?
The vb.net code:Dim fs2 As Object fs2 = CreateObject("Scripting.FileSystemObject")
gets an error when I try to make an executable file out of this program and run it via citrix server.
The error is, the executable file won't run at all. When I try to run this locally, there are no errors at all.
I have a treeview dragdrop event written in VS2003. It works perfectly fine when the application is running on desktop, until we move the application to Citrix. So, users are now running it off from Citrix, the DragDrop event doesn't work anymore. It doesn't even have the effects of allowing dropping.

View 3 RepliesI am connecting to Citrix database using SQL-defined ODBC. Having a problem with it. I am updating an existing application that uses the ODBC in SQL, and it connects fine. However, that database connection is secured, only available on the production side. The test side has a remote connection. I am attempting to change the remote connection values to match the parameters of the SQL-based ODBC, but the labels are different, and it doesn't seem to match. Specifically, I don't think I'm getting the DataSource correct. Also, it can't find the username and password that I use to log into the remoter connection - I get an error message "Invalid authorization specification".

View 9 RepliesI'm using this query:
Dim FilesDirsQuery = From file In
_directory.EnumerateFileSystemInfos()
Select file.Name, file.Extension
It gets all files and directories in the _directory. But how to order the query by extension and name?
So I found that I have to use this to order by extension:
Dim FilesDirsQuery = From f In
_directory.EnumerateFileSystemInfos()
Select f.Name, f.Extension Order By Function(f As IO.FileInfo)
Return f.Extension
End Function
And I have to use "ThenBy", but it can't be used in my example. So I tried:
FilesDirsQuery.OrderBy(Function(f As IO.FileInfo)
Return f.Extension
End Function).ThenBy(..)
But it say's that my nested function doesn't have a compatible delegate. So what should I do?
I've got a Samsung Q1 attached to my computer, and I was hoping to use the FileInfo / DirectoryInfo objects to access the file on the device, however what I right click on a file in windows explorer I get a location of COMPUTER/Q1/DATACASTS/mine.mp3, and when I feed this into the DirectoryInfo object I get "Invalid network drive"
Something tells me I'm going about this the wrong way ... Is there a differant object I shoud use, or is my location string incorrect in format
I have used log4net in winforms before. First time using with a wpf console app. The console shows up and the console appender works exactly as in the winforms app. However in winforms I never had to give the full path to the log4net xml file. It is located in the same place where all the cs files are. (the default place where VS 2010 puts all its source files. So
XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo("log4config.xml"));
works in a winforms app's Program.cs->main() but for the wpf version where I have my own Startup class with my own Main() (instead of the autogenerated and hidden main()) I have to change the line to look like this
XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(@"c:fullpathlog4config.xml"));
This took me quite a while to nail down so I thought it may be worthwhile to figure why this is so. Anyone know ? I am using log4net ver 1.2.10.0. The log4net dll and xml both have copy to local = true in winforms and wpf.

View 5 RepliesI'm having bizarre performance results of the methods in FileInfo class.I'm using 5 methods of the FileInfo class in the Paint event.The datagridview is bound to the dataset.First the application searches files in the RecursiveSearch. When rows are added to the dataset the Paint event is fired and the rows displayed are filled with extra information from the FileInfo class . In this case the performance is very good. If I remove the DoEvents() from the RecursiveSearch the 5 methods of the FileInfo class become very slow (about 0.25sec for each line of code)!When the search ends, the user can scroll down to see the other files listed.At this point the Paint is again fired. This time the 5 methods of the FileInfo class are again very slow!

View 10 RepliesI have been having problems with creating a download list of files for a downloader and was getting unexplained "File Does Not Exist" returns. My .avi files were returning found but but .exe and .txt files were getting the not exists.
I have now found by pulling in the whole directory and examining the file contents that my .exe files are showing ".exe.exe". My .txt files are showing ".txt.rtf". Wow, browsing the file directory in Server 2008 only shows a single extension. I don't see an option to display the extension as a column, just the "type". My directory looks like this:
Name Type
File1.exe Application
File2.txt Rich Text Document
File3.avi AVI File
I had renamed some of these files, maybe I just cannot rename files. I will try using originals ans see if I am ok. Maybe I need to rename the offending files without the displayed extensions. Is this just something weird with the server browser?
How to access the fullpath field in a fileinfo object
View 3 RepliesOK I am working on a windows service that monitors specific directories and checks to see if a file is changed. If a file is changed, it is attached to an email and sent to an admin.
The way I solve the problem...
I create a FileInfo object to do the following:
-I check to see if the file has an extension that is allowed to be attached
-I check to see if the file is under a max size to be attached
I create an Attachment object to do the following:
-attach the file to an email
I then send the email. The problem with this is when I edit the file after it is successfully attached the first time, I CANNOT save changes to that file. I get an error message saying that it is being used and cannot change it. My solution to this problem is to call the "dispose()" method of the attachment class. When i do this, I can edit the file all I want to and the first attachment works but after that the "dispose()" method always throws an exception and the file is never attached to the email when the file is edited again. Why is this happening?
