Create Txt File And Write To It Without Access Denied Lock?
Jan 24, 2012
1. I have to create a file. 2. Then I want to write a string into the text file.
I can do part 1 no problem with: File.Create(strFilePath) But when I try part 2 to write to the file it won't allow this as it's still being used:
sw = File.AppendText(strFileName)
sw.WriteLine(strCode)
sw.Flush()
sw.Close()
My code in part 2 works fine on a file that hasn't just been created.
How do I release the file from the File object?
There doesn't seem to be a .close or .flush option.

We needed an inter-process reader/writer lock.We decided to use a file and lock the first byte using LockEx and UnlockEx. The class creates a file in the system temp folder when it is created. The file is created with readwrite access and share read|write|delete.We also specify DeleteOnClose so we don't leave loads of temp files laying around. Obviously AcquireReader and AcquireWriter call LockEx with appropriate flags and ReleaseLock calls UnlockEx.We have tested this class using a small application that you can run several instances of and it works perfectly. The application that uses it has a problem, which we have managed to re-produce in another small test app. In pseudo code it is
Create InterProcessReaderWriter
Dispose InterProcessReaderWriter without acquiring any locks
Launch a child process which takes a reader lock
The first time this runs, it works fine. If you attempt to run it again, while the child process from the first time is still holding the lock, we get an UnauthorisedAccessException when trying to open the file.This appears to be a permission issue, not a sharing violation but all the processes in this test case are running as the same user.

I wrote an application which parses a website and downloads an mp4 file from website. User can select the path where he wants to download the video. When I try to download I get an exception for the file, Access Denied to Path. When I gave the permissions to folder that I chose, then works fine. How can I resolve that problem? End-User will select the folder. How do I change the permissions?

Typical problem, but I've done everything I can possibly think of to get this to work. I set the NETWORK SERVICE and ASPNET accounts to FULL CONTROL on my PC. I'm using the built-in Cassini web server to test my application, with no luck. I even tried to make a folder outside of the APP_DATA folder, and is still says Access is Denied.

Im trying to write to a file I created and place "Unregistered" in it. Thought it would be a simple task but keep getting an error. Its happening when I try and open the file to write. This is the error: Access to the path 'G:\Projects\Project\pbss\bin\Debug\5\pbssv\Data.DB' is denied.
Ive tried adding the file attributes to read-write and still get the same. Most of the code ive looked at via a google search points to the same as ive got for the Added default value area. Im not sure if there is a conflict between the 2 different ways im accessing the file when creating and writing too? [Code]

ran into an issue but i have no idea why. I made a program that reads in a text file. I tested the program and it worked perfectly. I made the setup file using the setup wizard, installed the program on my computer and tried to test it and it gave me anerror about not being able to access the text file. I attempted to run the program right in VS because it had worked fine before and now even in that i am getting an error saying it cant access the text file. I dont know why it did work and now suddenly it

I have difficulty in removing the LDB generated by the "CREATE" method of ADOX in the following code segment.Aims: Create (on the fly) a new access database and then export data (says Arena modules) to that newly created database.
Expected: The newly created access database should be able to be used by some external operations, say Access.exe, after the end of the subroutine and without exiting the current VB program.
1) I tested that the "Arena code" do nothing about the create/release of the ldb file.
2) I tested the "Exclusive Mode" in connection string, but the access file is still locked by the vb program.
3) I tested under both inside the VB environment, and directly invoke the generated from Explorer, and same results.
4) Other database formats is not the options to me. (due to Arena export limit)
5) It is not a web app.
Code:
Sub Method1()
Dim logs As New System.Collections.Generic.List(Of String)
Dim arenaApp As Arena.Application = Nothing
Try

Platform:
Windows 7 64bit, Office 2010 (32)
VB 2010 express
Lib: MS ADO Ext. 2.8 for DDL and Security

I am currently using the below code to upload a file and display progress. It works fine except there are a few things I would like to do differently.
I am using the main FTP account for my website which has access to all of my files. I set up a different FTP login to use that only has access to a specific folder, but when I try to use it I get: Error 550 No such file or directory or access denied.
This FTP account allows access to: mywebsite.com/upload/users/ only If strFTPAddress = mywebsite.com/upload/users/ I get error 550, I've tried a few other things too and it's told me that it's an invalid URI
Basically what I want to know is if and how I might be able to connect using my second FTP account so that I only have access to the upload/users/ directory.

I cannot figure out how to get past this error. I have 1) Given the user "everyone" access to the entire directory that this dll is contained in 2) Deleted the dll and rebuilt the project 3) Deleted the Temporary ASP.NET files in the Windows Directory 4) Restarted IIS 5) Tried to change to a different user in IIS security including trying ASPNET. we are not using windows authentication. 6) Even copied that dll from other machines.
Here's the error. I have no clue at this point if it's code missing inside it or something else wrong with it or my setup. Other people on my team are using this dll ok. Could not load file or assembly 'Anthem' or one of its dependencies. Access is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

We have a site that is public facing, let's say it's [URL]. When the SSL is implemented, [URL], I can no longer access the jQuery 1.4.3 file on my own server. Furthermore, after a tweak to the security setting, I was able to get past the 'Access is Denied' error, but the first call was null. I understand there is a problem with different protocols actually being within the scope of the cross-domain problem? Is that true? And if so, will this now require JSONP?

I've been doing some more experiments and have summarized the query as below: I've created the simplest application. A project with a plain form, which writes text file within its application directory. Simple as that.Supposing this was my application which I want to distribute on the world web. I've created a basic installer for this using NSIS installer. The Installer installs my application in a folder created inside Program Files. The OS is Windows7 and UAC is enabled.Now I know many people have been facing difficulties in accessing files inside the Program Files folder. My app is simply creating a plain text file, nothing more, and within its own application directory. It is giving Access Denied error. But if I right-click on the EXE and run it as Administrator, then it works ok.The only solution thats available is not to write in the application folder, and write text file in some other folder which is not protected. My question is that other programs that are installed on my system are also doing it. I have a temperature monitoring software called SpeedFan on my system, it creates log files within its app directory. All other softwares create log files within their app directories, why cant I?I just have to make a small log file for my application and Win7+UAC is not letting me do it. I don't want to write the small file in any other folder. How are the other softwares accomplishing this ?

I thought I postet this yesterday but I can't find my thread so if this is a duplicate please point me at the original one. Background: I need to create a user account and Modify it's registry before the user logs on the first time. Creating the account is done by using the Winnt provider (works great). To create the profile I'm trying to use Process.start to launch a process as the newly created user. With the use of loaduserprofile property the users profile gets created and i can do my regwrites without problem.
