My application creates a file by writing to System.AppDomain.CurrentDomain.BaseDirectory() & "data/" & filename...Now this works fine usually, but I just added a setup utility to the app, so now it installs to the program files directory. It installs correctly and creates the data folder, however when it tries to write the file it gets an exception "unauthorized access".
View 3 RepliesI am trying to get a list of files using this line of Dim files() As String = IO.Directory.GetFiles("D:", "*.*", SearchOption.AllDirectories)But it errors out on folders that are inaccessible, like the RecycleBin folder & the program stops. So how do I get a list of files in all folders, while skipping the inaccessible one

I'm getting error "Unauthorized Access Exception was unhandled."

I've googled the net and found that registry permission elevation is required for admin tasks, Is there away to take registry key ownership through VB.Net code??
Ive created a simple application that works fine when i debug and test it though visual studio but when i deploy the application, download it and install it onto my machine i get an error.basically when the first form loads it checks for a file called "New Folder" in my program files folder on my machine if the file is not there, then it adds the file. the code im using to do this is:
If System.IO.Directory.Exists(My.Computer.FileSystem.SpecialDirectories.ProgramFiles & "New Folder") Then
Exit Sub()

I am creating a file and then trying to read and write to it. I'm coming up with an UnauthorizedAccessException wa unhandled. My question is, How do I get around this properly or otherwise improperly to read and write to my text file?

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
I am deploying my application on a 64 bit windows 7 system (setting the platform property to x86) , after the installation process the app needs to set its connection string in the config file; and this is where I am having issues, the app is not able to write to the config file if/when its located under the program files directory (no admin privileges??), the app works fine when installed on a public folder.Please let me know how to give admin or write access to my app when its installed to the default program files directory

View 5 RepliesOk I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloads files from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.
After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.
So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install and work like when we installed on XP.

I had an exercise where I was supposed to have a button open an openfile dialog box, let the user select a file, then another button that would save the file with the extension ".bak".

I'm making a map creator that chooses images randomly from various sets. What I'm trying to do is set up subfolders in Resources and put the different images in each folder - e.g., a folder for streets, a folder for monuments, etc. Then I just make an array of images out of the files in the folder, and pick one.
For some reason, I can't find a simple way of getting at the subfolders. I've tried using IO.Path.GetFullPath(My.Resources.ResourceManager.BaseName) and appending the folder name to the end of it, but no luck.
Is there some other way of getting the path? Is it even possible to use subfolders of Resources? Is there a better way of doing what I'm trying to accomplish? I'd really like to avoid creating the image arrays by hand.

how to download folders and i know how to search for folders but how can i download a folder into the above directories without knowing the name of the user account.
If any directory within a set being searched by the [URL] or [URL] methods contains a junction point, the entire method fails and returns zero results on my tests under VB 2008. I would like to make the call more robust: to return the folders or files not blocked by access restrictions and to note the folders which were blocked. Do those methods offer a means to do this, or is a recursive folder-by-folder call necessary?
View 3 RepliesI'm trying to write a console application that can modify registry subkeys on remote pc's in the same network. I have it working in my own environment but when I install on the customer machines I'm getting unauthorized access when it hits the OpenRemoteBaseKey. The security settings in the application properties is set to full trust application so I'm not sure why it won't work.
I'm using Visual Studio 2010 and first I just installed it on the customer machine and when it wouldn't work I ran the source code in Visual Studio 2005 which is on the customer machine but got same results.I can run the app directly on the remote machine and it will change the registry subkeys as directed, I just can't do it remotely. RemoteRegistry service is started. Both machines are logged in as administrators.

I have a VB project that I created a simple setup project to deploy. It installs fine except for one problem. It crashes because it can't read its own application directory. Included with the program are an xml and schema file that it needs to read when starting.dditionally it may create a log file, also in its application directory. Either of these will return errors under the default install. This was not an issue when running the program in VS and if modify the program to work with another directly like C:Temp. I have a workaround in which I change the permissions of Users group to Full Control for the application directory

View 4 RepliesI'm getting a problem when writing text files using StreamWriter. The files read fine and they write fine if I'm not overwriting an existing file. They also write ok as long as I'm not writing over a file that only has one digit at the end of the name. For some reason when there are 2 digits at the end it crashes when I'm trying to save over an already existing text file. Here's my code.
StringForTextFile = "C:" & Folder4PS & "" & IDCodewDashOrN & "Series" & Series & "ScreenNumber" & ScreenNumber & ".txt"
LblTesting.Visible = True ' Testing
LblTesting.Text = "StringForTextFile = " & StringForTextFile
[code]....
above but 've tried all the different Encoding possibilites. Unicode, UTF32, UTF8, UTF7 as well as without those parameters listed where the close parentheses is right after StringForTextFile. I get the same result. If I'm writing a new text file that doesn't exist, then no problem or if I'm writing over an existing text file but it has 0 to 9 at the end then I'm ok but if I'm writing over an existing file and there is 10 or above(haven't tried triple digits or all values) then my application crashes. You see the test label in the code above because I was looking at exactly what file it was trying to overwrite and it is just as it should be.
Should I be using a different procedure? An example of a string that would cause a crash for the string StringForTextFile would be:
C:Name of My AppSeries1ScreenNumber10.txt
If it was being written for the first time then no problem or if the 10 at the end was 0 to 9 then no problem also. I've also tried and originally had it set up where there wasn't an If File.Exists(StringForTextFile) = True Then statement. It just always used the same code whether writing or overwriting and I wasn't having a problem that I remember. For some reason I started having a problem recently and I put the alternate methods of writing in.
