Check For Valid Path


I am using a registry entry make the save path for a file "sticky" between program executions. However, when the user uses a removable drive and the registry gets set to that path, the app will crash when it tries to open the file at that path. (i.e., the user saves to a USB drive at f: emp, then pulls the drive out. Next time the program is run it tries to save to path f: emp, which doesn't exist, and the program blows up).I guess this could be fixed with error handling, but is there an easy way to programatically check if the path is valid BEFORE trying to open the file? Thanks!

Programming :: Script To List Files In A Given Directory? www.linuxquestions.org

writing a small script which will display the files in a given directory? So I should be able to give a directory path (as an argument or any sort) and then be able to see all files within that Dir. If I dont give a path then the script should list the contents of the current directory. I kind of got the pseudo, it is something like this 1. Request for a directory path 2. Take the directory path and assign to a variable eg: $1 3. Check if $1 is valid i.e if a path is given by the user 4. If $1 is a valid path then list the contents 4. Else if $1 is not valid, print the list in the current directory

Make Sure A File Path Is Within A Given Subdirectory? stackoverflow.com

I want to make sure a file path set via query string does not go outside of the desired subdirectory. Right now, I am checking that: The path does not start with "/", to prevent the user from giving an absolute path. The path does not contain "..", to prevent the user from giving a path that is outside of the desired subdirectory. The path does not contain ":", to prevent the use of a url (i.e. "http://", "ftp://", etc.). Should I ever run this script on a Windows server (not likely), this will also prevent absolute paths beginning with a drive specifier (i.e. "C:"). Note: I'm aware that a colon is a valid character in a Unix filenames, but I will never be using it in a filename. The path does not start with "". Just in case I change my mind about running on a Windows server, this prevents Windows network paths from being specified (i.e. "\someserversomeshare"). Again, I'm aware that a backslash is a valid Unix filename character, but I also won't be using it in any filenames. I have a PHP script that takes (via query string) path to a sample source file to be shown to a user. So I might give them a link like "view_sample.php?path=accounting_app/report_view.php" or "view_sample.php?path=ajax_demo/get_info.js". The script looks basically like this: $path = $_GET['path']; if(path_is_valid($path) && is_file("sample/$path")) { header('Content-Type: text/plain'); readfile("sample/$path"); } My concern is that a malicious user would see the url and try to do something like "view_sample.php?path=../../database/connection_info.php" and gain access to a file which is not in the "sample" directory. Are the four checks I defined above (which would be implemented in the path_is_valid() function) sufficient to lock out a malicious user? (Also, I think checks 1, 3, and 4 are basically irrelevant since I am prepending a relative path, but if I didn't do this would the checks be sufficient?)

Question About Executing Files From Subdir www.xtremevbtalk.com

Quick question about executing files that are in a subdirecoty where the program is.I have an checkbox that allows the user to use the complete path to the program in the subdirectory or a short path.The code at the end of this post for the complete path would translate to: Code:C:BootDreams oolsCdirip.exe "C:Image.cdi" "C:BootDreams" -cdrecordFor a short path: Code:toolsCdirip.exe "C:Image.cdi" "C:BootDreams" -cdrecordHere's the code the above bit was translated from: Code:temp$ = IIf(mnuCompletePaths.Checked = True, App.Path & "", "") & "toolsCdirip.exe """ & txtImage.Text & """ """ & App.Path & """ -cdrecord"After reading up on "A quick note on App.path" I realized I should probably make the curDirector() function.I guess what I'm asking is, does that look safe to use with both complete paths and the short path without making the function? I'm getting a file not found error when using the complete path but not the short path.I believe this part of code is where it it giving the error since the file that Cdirip gives does not get renamed: Code:If Dir$(IIf(mnuCompletePaths.Checked = True, App.Path & "", "") & "TAudio01.wav") = "" Then If Dir$(IIf(mnuCompletePaths.Checked = True, App.Path & "", "") & "BootDreams01.iso") <> "" Then Kill IIf(mnuCompletePaths.Checked = True, App.Path & "", "") & "BootDreams01.iso" End If Name IIf(mnuCompletePaths.Checked = True, App.Path & "", "") & "TData01.iso" As IIf(mnuCompletePaths.Checked = True, App.Path & "", "") & "BootDreams01.iso"End If

How To Identify COM Ports Irrespective Of Hardware We Are Using ? www.codeguru.com

Hi,I want to know how many COM Ports are available in the system.. And out of them how many of them are valid COM Ports.. I could achieve to locate how many COM Ports are available by searching in the Registry for this path (hkey_local_machine/hardware/devicemap/serialcomm). This is valid in some hardware and the same path is not available in some other machines. And I could check the validity of the COM Port using the MsComm Control by which I can know whether the Port is valid port or not..Now I want my solution to be generic.. Irrespective of the hardware we are using it should display me all the COM Ports which I am using including COM1 / COM2 / COM3 / COM4 upto COM8 if present.I have used the following Registry API's in solving this problemRegOpenKeyEx , RegQueryValueEx , RegEnumValue , RegEnumKey .. and some other constantsPlease let me know some way out to solve this problem.RegardsPrasad

I'm really just trying to get a path to an application from the user. I have the application name as the only filter selected - so the user has to either cancel or find the right file (so I know the path is valid).

Error:"Conversion From String "User" To Type 'Integer' Is Not Valid." www.vbforums.com

When trying to combine the User path with another path, I get a an error:"Conversion from string "User" to type 'Integer' is not valid." vb.net Dim Variable As String = IO.Path.Combine(Environment.GetFolderPath(Environment.UserName), _"AppDataLocalLowSunJavaDeploymentcache") I guess my understanding of how to combine paths is a bit unclear.

Valid Filename www.vbcity.com

how to check if the string contains a valid filename (and filepath)?the filename is not existing yet (so it's not the same as the FileExist test) andthe file extension could be anything, as long as the path and name are valid.for example?c:folder1file1.txt - > valide: emp est.exe -> validadeda e?xt.txt - > not validthe way i do it right now is i try to open the file for output using the following syntaxCode:    Dim ifile as Integer        ifile = FreeFile()    Open strFilename For Output As #ifile     ...then i just check if it generates an error or not. if it does, then i know stfFilename isnot a valid filename.i don't think this is the best way of doing it.

Check If Path Exists Using Fso www.vbforums.com

I have a string variable that holds a directory path...I am copying a file to this path, but need to check to make sure the path exists first: the path looks like this:c:programmingmydirectoryDo I have to check all directories in order to create this path ifit doesn't exist, such asCheck(C:Programming) if doesn't exist, create itNow check (C:Programmingmydirectory) if it doesn't exist, then create it.Or is there a way I can just give it the one path:C:ProgrammingMyDirectory and if it doesn't exist, it will automatically create the other folders underneath if they don't exist????????

"could Not Find Part Of Path" Error www.vbdotnetforums.com

I'm running a small piece of code during the startup of my application that checks the version number of a matching file on a mapped network drive against the current version of the executable running. If the exe on the network drive is newer, it runs a separate application that copies the network version over and relaunches the application. This setup works flawlessly in XP, but it's giving me the following error in Vista and Window 7:"Could not find part of path: (path to executable)" The problem is, I can copy and paste the path in the error into the "run" dialog, and the path is valid.It's a simple path and filename, so escape characters should not be the issue. An example path might be: H:deploy_directoryexeName.exe

Check If File Exists On Server Based On Full URL stackoverflow.com

I have an app that generates invoices in the form of PDF files stored in a directory on my server. Before mailing out this invoices I'd like to make sure that the URL (not server path) which I store in my DB does indeed point to a valid PDF file. Something could have gone wrong that wrote a value to that field in the db, but for example the filename is missing; meaning the file is not in the specified directory. AFAIK file_exists just checks server paths but not URL's. I could always store the server path too, or assemble it, but I'm wondering if i can do this check based on a full http url ending with a filename?

VS 2010 Converting Recursion To Iteration? www.vbforums.com

Is it possible to make this function iterative or must it be recursive? The Function traverses a grid of x length and y height. At each point in the grid, it checks all of it's neighbors to see if they are valid, meaning they exist in the grid and haven't been used yet. The function works in it's current form but I was wondering if an iterative version would be more efficient. PathManip is a Stringbuilder, stores the path currently being manipulated. PathQueue is a List(Of String), stores all paths yet to be traversed. IsPathAlreadyUsed is a boolean function that checks whether or not a specified point has been used in the current path.
