Changing File Attributes (BitWise)?
Jun 14, 2009
m_ArchiveBoolean, m_HiddenBoolean, m_ReadOnlyBoolean, m_IndexedBoolean, m_CompressedBoolean are all form level booleans that's set from their appropriate Checkboxes on the form before this code runs in a BackgroundWorker.
Why is it that this code works:
Try
Dim fi As New FileInfo(element)
With fi
If m_ArchiveBoolean = False Then
[code]....
In this 2nd one attributes are being changed, but they're the wrong ones and I can't pinpoint it right off hand.
Edit: What the overall goal of this is that if the user has the attribute checkbox checked then the file needs to have it set, other wise the attribute (if it's present) needs to be unset.

I'm writing a VB program that will delete the contents of several folders, but it leaves the top folder. For example, after graduation and summer school, we delete the folders that belong to the (now) prior students. Also, we retain the folders for the returning students, but we delete the contents of their folders. Every year, all students start out with empty folders. We do this practice to manage our disk space.
With a read-only file, via code, I first change the attributes of the file to normal and then delete it, via
SetAttr(fileItem.FullName, FileAttribute.Normal)
fileItem.Delete()
I'm looking for a way to change the attributes of a folder from Read-Only to something else, like Normal.

Alright so heres the issue when this code runs nothing happens! This is all I could find on the internet on how to disable an account and then remove it from the GAL.
Dim Val As Integer = CInt(AdObject.GetDirectoryEntry.Properties("userAccountControl").Value)
AdObject.GetDirectoryEntry.Properties("userAccountControl").Value = Val Or &H2
AdObject.GetDirectoryEntry.Properties("msExchHideFromAddressLists").Value = "TRUE"
'AdObject.GetDirectoryEntry.MoveTo(MoveTo)
AdObject.GetDirectoryEntry.CommitChanges()

I have a lot of video I'm in the process of indexing and I'd like to gather information about the videos for queries and stuff. When I right-click a video and select properties, I can see a list of values under the summary tab: Audio Bit Rate, Sample Rates, Title, Comments, Duration, etc.

I have searched a lot on the web about changing file attributes in .net , it takes me a long time to get the final code but it was really good. But after all of my search I didn't know why we use "And" when we compare file attribute like this:
If (System.IO.File.GetAttributes(FilePath_txt.Text) And System.IO.FileAttributes.Hidden) = System.IO.FileAttributes.Hidden Then
MsgBox("File is hidden")
Else
MsgBox("File isn't hidden")
End If
Otherwise when I want to set Multiple attributes for on file I have to use "Or" with it like this
System.IO.File.SetAttributes(FilePath_txt.Text, IO.FileAttributes.System Or IO.FileAttributes.Hidden Or IO.FileAttributes.ReadOnly)I know this isn't a big problem but , I can't write a code I don't know how it is actually works.

I am trying to read all the attributes, there are 3, from a single node. This is what I tried from an example I found:
Code:
Dim xl As New XmlDocument
xl.Load(XMLfile)
Dim rn As XmlNode = xl.SelectSingleNode("p1")
[code]....
I have used a messagebox to show the xl.OuterXml, I see the file is loaded.

I am trying to figure out the numSamples in this:The canonical WAVE format starts with the RIFF header:
0 4 ChunkID Contains the letters "RIFF" in ASCII form
(0x52494646 big-endian form).
4 4 ChunkSize 36 + SubChunk2Size, or more precisely:
[code]....
This works fine for getting the wave file info, It just doesn't display the numSamples which I need.

So I have been searching around the next and keep finding solutions that all have errors due to upgrades. Basically what I want to do is load the following type of XML file when a button is pushed:
<?xml version="1.0" encoding="UTF-8"?>
<!-- Do not edit this file -->
<DATA version="1.0" xsi:schemaLocation="[URL]" xmlns="[URL]" xmlns:xsi="[URL]">
<NOTES> <NOTE NameId="Name1" Colour="13" PNotes="Test7" />
[Code] .....
But after that I want to sort out the attributes. I want all of the NameId's to go into a ListBox. After I get that problem sovled I am wanting to have the info in the PNotes attribute to be displayed in a TextBox when the connecting NameId is selected in the ListBox.

Does the IO.File.Copy method preserve file attributes? Especially, if I have a write-protected file, will the copy be write-protected to?

I have an application that uses a text file for its settings. This file is placed in the application folder but deployment sets its file attributes as "Read Only". I have to manually change this attribute every time I deploy the application or an upgrade. I tried (successfully) to place the text file in the "Documents and settings|All users|Application Data" folder, creating a specific folder for my application in which to place my file. The folder and file were created by the setup process but then, users who did not have admin rights still did not see the file, let alone open it.
I have gone back to placing my text file in the [Programs files]|[Manufacturer]|[Application name] folder but am saddled with manually changing the attributes. Is there a way I can do this programatically during deployment (e.g. by some post-deployment process)?

result = SendMessage(buttonhandle, BM_GETSTATE, 0, 0)
buttonChecked = (result = BST_CHECKED)
Now I want to know whether the bit for BST_CHECKED is turned on or not.
How would I do that?
I can do
buttonChecked = (result % 2 = BST_CHECKED)
Is there a better way?

Original Code (VB.net): curStyle = curStyle And (Not ES_NUMBER)
Changed Code (C#):
curStyle = curStyle & (!ES_NUMBER);
But it is giving me this error: Operator '!' cannot be applied to operand of type 'long'ES_NUMBER is of data type long.I tried changing it to int, string, etc. All doesn't work.

The following function copies a file from Source & Path to Dest & Path, normally setting file attributes to normal before copying.Yet, a user of my app has reported it to fail when copying readonly files, returning a permissions-related error. The user is however running the code as administrator, and the error happens - quite strangely - on the SetLastWriteTimeUtc line.Although the code reports that the file attributes are set to normal, windows explorer shows that they are set to read only.

The interesting thing is, that when I try to shift any number greater than int32 in .net, it yields bad results.. Every number under int32 (2147483647) yields the same results from php and c#.net or vb.net Is there a workaround for this in .net?

Did anyone else read this article under Visual Basic News? I thought it was a very bad treatment of the subject. I especially don't like articles like that when the code they post relies on Option Strict Off.

I want to perform a bitwise-AND operation in VB.NET, taking a Short (16-bit) variable and ANDing it with '0000000011111111' (thereby retaining only the least-significant byte / 8 least-significant bits).

According to MSDN The And operator can act as a bitwise operator OR a logical operator.The only way to know if it is used as One operator or another is, If it is on the right side of an assignment operation? for example x = 3 AND 5. I cannot find any other instances where the bitwise operator would be used instead of the logical operator, are there?

I have an abstract user control(baseModule) that has a property that I plan on using a bitwise comparison on to determine what export types are supported by that module. In the designer of a module derived from baseModule, I am presented with a combobox with the ability to just select a single value (Html, Xml, etc.) I would like to be presented with a drop-down checked listbox so I could select which values I want.How can I accomplish this inside of VS2008? I've seen other properties support this.

I have a little vb.net script that will copy a file, set its attributes to Normal, update the file time, and then set back the attributes to match those of the source file.
If IO.File.Exists(Destination) Then IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
IO.File.Copy(Source, Destination, True)
IO.File.SetAttributes(Destination, IO.FileAttributes.Normal)
[code]....
I however I'm encountering a quite strange problem. On some configurations, IO.File.SetLastWriteTimeUtc triggers an UnauthorizedAccess error, although the IO.File.Copy instruction worked very well.

I've got an issue with an Access97 replicated database that I'm writing a small monitoring app for. I've got FSW's to track changes to the necessary files, but am having some issue in enumerating exactly what has changed in some instances, specifically when attributes may have changed. I'm using a similar strategy to track this as I did for changes in size. I've got a Private class variable for the size of each file and a local method variable and compare the two, when different, update the class variable for the next comparison.

I am building the 'TheBeerHouse' project in vb.net (the book is written in C#). Once I understand the concepts, I can usually convert it to vb. However, there are a few areas that give my some problems (which I will address individually). The first issue I have is the C# 'base' to VB 'MyBase'. [code] My understanding of this conversion is that I need to grab the attributes of the <articles> element under the <theBeerHouse> custom section in the web.config file.This code does not compile and the get the following error: 'MyBase' must be followed by '.' and an identifier.
