I recently reformatted my computer and now that I try running a program I made beforehand, I always get an UnauthorizedAccessException when the program tries to access the D drive. How do I make it authorized? I tried changing the security settings for the D drive but that wasn't really much help.
View 1 RepliesI am trying to run a visual studio 2010 app from a windows 2003 server machine that writes xml files to a folder stored on a remote windows 2008 server. I mapped the server drive and can access the folder manually but in the code the 'access is denied' error is hit when the file path declaration is hit for that 2008 server folder. I checked the access writes to that folder and made sure it is shared for that user. Also the user I am logged into on the source server has admin rights so should it not be able to access the mapped drive through the application?How do I grant my app access to that or any folder on that drive on the remote server? I had this issue before but cannot remember what I did to clear this up.
View 1 RepliesIn my VB.NEt 2008 application, I am frequently creating and killing the file Fileopen and Kill(Multiple times ). It was working fine with Windows XP. But in Windows 7, it is worjking fine for some time (creating and killing theile properly) and then t is creating unautoriszed Access exception after some time .it does not happen immediately and it happens intermittently.

I'm running windows 7 64 bit and using VS 2010. I'm trying to use the filesystem.getfiles to find a file on the computer and return the path for it. However, when I search C:/ and its subdirectories, it always throws an error: "A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll"
I've looked everyone online and can't find a solution. I have administrator privileges and really I dont want people who use my app to have to adjust security settings for this to work. Is there not a way to search the C drive for a specific file and return its path? [Code]
I coded a program to access a Microsoft Access 2010 database. The program is written using Microsoft Visual Studio 2010. I get the error message that the database I'm trying to access is in an invalid format. look at the code below to see what I missed. The error is in the datasource statement.

We have around 2000 staff. Each has a shared drive to store some of their files. This shared drive points to a central location on our network.[code]...
Each user will have a folder within the root "ournetwork" labeled with their username. I do not have to worry about the directory creation as that's already done for me. These users are all tied into our AD for authentication. Folder name == AD username.
We would like the ability to allow our users to access their mapped "F" drive from outside our network through a web page. I understand that the programming involved (assuming it comes to that) will not rely on their mapped drive but rather the UNC path as posted above.
I am open to suggestions on how to get this accomplished. ASP.NET? Is there just an IIS solution like WebDAV? (although client-side WebDAV on win 7 seems to be broken, so that may be off the table).

View 1 RepliesI have a program designed in VB.net for a wafer probing system. The software has 3 main components that come standard and three that are options. When a customer decides not to have the three options they are disabled but still in the program. If at some point they decide to buy the options, one of our technicians would have to go there and be able to access the program with an administrative account to enabled the components.
Does anyone have any suggestions on what the easiest way to accomplish this?
So I have this program which I can use to drag files in it and do something with it, and when I run it as administrator, it doesn't let me drag the files in at all, but when I run it normally it does. Is there a reason behind this? And how would I go about fixing it?

I can't open an Access database on a mapped drive. However it works if I use the UNC path. how I can get this to work? See the code below for an example of what works and what doesn't...
Code:
mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=\tiger-2000dvb_mt7MTrackBE.mdb" ' This works
mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=T:vb_mt7MTrackBE.mdb" ' this does not work
Dim objConn As New OleDbConnection(mConnString)
[code].....
The error message I receive is...'T:vb_mt7MTrackBE.mdb' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.I've done the obvious and verified that t:vb_mt7MtrackBE.mdb is a valid path.
My software handles multiple operations on files, and I have now finished writing the related functions, using the System.IO classes. I now need to add support for network drives. Using a mapping works very well (although Directory.GetFiles is a bit low, and I don't know why), but I'd now like to be able to deal directly with paths such as \192.168.0.10Shared FolderMyDrive. Is there any way to handle this type of paths other than mounting the drive to an available drive letter, using the newly generated path, and then unmounting?
View 4 RepliesI had a basic text file reader/writer program that wrote and read from a mapped, shared drive up and running for a couple weeks. I wanted to add just a couple more things that shouldn't have effected the program (the ability to write another text file), and now the program can't find the shared drive. The error I get is: Could not find file '<file location>' with <file location> filled in with either the mapped name of the drive (X:) or the unmapped name (\servercomputer). Both are copied directly from windows explorer, so I know the path is right. I'm a bit of a beginner, but I'm pretty sure that all the required permissions are in place, and all users have access to this drive.
To further complicate things, it is not consistant. Some commands appear to have no trouble reading off the mapped name, but don't read the unmapped name, and vice versa. Others won't take either. Sometimes the code will execute perfectly up to the middle of the code (accessing the shared drive a couple times), and then it will give this error. If anyone could point me in the right direction,
I am trying to read some data from the MBR using CreateFile, but I cannot get it to work without admin rights. The code I am using is like this:

I am trying to create a program that downloads audio files via FTP, converts the audio to mp2 if necessary and copies them to a certain directory for consumption by our automation system. (I am a radio station engineer.)I am using the open source converter FFMpeg to convert audio files to mp2. This is a command line exectuted program. Here is the command line that I use to execute the external program with the input and output audio files at the root level: cmd.exe /k ""C:New Folderffmpeg.exe" -i "C:Test.mp3" -y "C:Test.mp2"" This command line works correctly whether I am using Shell() or System.Diagnostics.Process (Process) to execute the external program. I am going the Process route so I can know when the conversion has finished.Now, I really don't want to use the root directory for this but when I go below root with this line using Process the external program will not execute:[code]Can anyone tell me why that line will not work with Process though it works as expected with Shell()? I can't figure out how to stop the external program to get some feedback as to what its problem is.
View 7 RepliesI am trying to migrate from XP & Net 2005 to Windows 7 & Net 2010 My intention was to replicate net 2005 first & get projects working before installing net 2010, as I envisaged all sorts of learning tasks which I could resolve at a snaill pace whilst still being able to operate with net 2005
Stage 1 was to load 2005 on Windows 7, no problems yet.
Stage 2 open the Virtual Cryptainer drive
Stage 3 load a project ( was never a problem with XP)
Stage 4 project errors reported as not being able to access linked modules in another folder
Windows 7 seems to have more folder security/permissions than XP, so I altered as many folders being associated with the project but to no avail.By changing the virtual drive folder permissions are they amended on the drive folders (if so how would this affect going back to XP)
are the folder permissions somehow stored in the registry, which means if I restore an old virtual drive from backup, does W7 now know the permissions & apply them to the back up drive, even though those folders were never accessed in W7?By the way, anybody reading this that does not know about Cryptainer, should look at it very seriously, I now have no data files on drive C, & all my data files in the cryptainer vault are compact & virtually impossible to be opened without a password up to 100 char long!

I'm looking for a way to monitor drive activity using Visual Basic 2008. I want to create a small utility to simulate an LED in the system tray for drive read/write activity. I've found several such utilities that do this, but they all lack one thing or another, or they are over bloated with stuff I don't want or need, etc. I want to write my own so it will be like I want it. To get started, I need to know how to monitor drive activity.
View 3 RepliesIs there any way to do so? I know its possible to programmatically eject/retract the cd drive SOMEHOW, cause Roxio does that when it prompts me to insert a disk.

I am nearly positive there is some way to do this, I just don't know the methods to call.
Is it possible to read the serial number of a USB drive using VB.
View 3 RepliesThe VB.Net program in question creates several files, adds them into a zip file (using DotNetZip), and saves the zip file into a given directory (which the user chooses). This comes out just fine. But when I use it to save directly to my USB flash drive, I can't eject the drive without shutting down the program first.I've tried disposing the zip object (from the DotNetZip library), doesn't work. I also tried setting FileIO.FileSystem.CurrentDirectory to somewhere else on the machine, still no.
