File I/O And Registry :: Finding Path/filename Associated With Extension?
Jun 24, 2011
I suppose technically this isn't .NET specific but I suspect this is something to do with the registry and I'm using .NET!I'm trying to find out how to get the fully qualified path relating to a file type.For example, the system knows that to open a PDF file it needs to launch C:Program FilesAdobeAdobe Reader 10.0Readeracrord32.exe
I've had a good long search through the registry and found a lot of references to the adobe path probably too many - and I've edited them to try and "break" the process so I can identify which one is used to discover the path but with no luck. I'm assuming this has something to do with HKEY_CLASSES_ROOT?

I got an easy one this time How can I get a file knowing the path and the name of it, but not knowing the extension which I need to get. You can see at the moment I use this silly code which finds and opens some main filetypes for me, but if I could get hold of the file extension just by using the filename and the path I could open any document or image...

I have an application, that I have integrated into Windows Shell, for this example I will use Notepad. You can right-click a file on the desktop and select 'Edit with Notepad', this launches(if I am not mistaken 'NotePad %1') notepad, and opens the file right away for editing.For my application I need this to get the file name, so basically I would right click on my application, and it will run and have the filename for me to use inside the application.

We have a network folder that is the landing place for csv files processed by different servers. We alter the extension of the csv files to match the server that processed the file; for instance a file with the name FooBar that was process by Server1 would land in the network share with the name FooBar.Server_1.
The information I have available to to me is file name: FooBar and the path to the share. I am not guaranteed the extension as there are multiple servers sending csv files to the network share. I am guaranteed that there will only be one FooBar file in the share.
Is there a method in .net 2.0 that can be used to get the extension of the csv armed only with the path and filename? Or do I need to craft my own?

I am looking for an advise on how to find out the extension of the file only knowing the name and the location of it. I tried getextension method and some other but they don't seem to do anything to me.
E.G.:
Dim FileFullPath As String = "\SERVERPublicCRM_LibraryOrderMGMLetters" & datagridLetters.CurrentRow.Cells.Item(0).Value.ToString() & ".pdf"

I get the common error: " 'File Name' is currently being used by another process..."
My problem is that I have two forms. If the file doesn't exist in the one then it creates the file and opens up the other form, if the file exists it doesn't do anything, however, in the other form that it opens up I have it "attempting" to write text via StreamWriter. But my problem occurs when the StreamWriter tries to open the file for writing, that is when the program tells me that the file is currently being used by the other process.
In my first form I close the form via Form.Close and all I am using to create the file is System.IO.File.Create. Now I know that the System.IO.File.Create is causing the error because I have this process checking the very first thing on the program load. I am trying to find a work around the System.IO.File.Create but no luck here... I am trying to create a .txt ... lets say test.txt .

How would I do that? Sample code is below that demonstrated that the file I opened contained the full path and file name.
I want to extract just the path and serialize that to the user.config file as a UserSetting value. Then next time the user opens the dialog box, it uses that saved path string to go immediately to the location previously used.
If openFileDialog1.ShowDialog() = DialogResult.OK Then
Properties.Settings.Default.persistConnectionType = openFileDialog1.FileName
Properties.Settings.Default.Save();

in my program, i use that code for getting the file path of a process, once it gets the path, it is put into a list view which has details like the task manager. the code works fine the first time, but with a little bug that is, when it reaches the vhost of my program. For some reason, it just copies the file path of my program even though the process has changed. After the code has gone through, i want it to refresh the list so as doing the same as when loaded...so I let it refresh and once again it copies the path of the vhost, but this time it has basically taken over every process' location. So in turn, I only get returned my programs location, for something like the task managers location, where it would be like "C:Windowssystem32skmgr.exe"
Here's the
VB
Private Sub frmmain_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim Process As New Process()
Dim Count As Integer = 0
[code]....
The refresh code is frmmain_Load(Nothing, Nothing) just to make things easy for me right now, while i get that part of the program going. To me it seems to be working fine, but why it does that what it does, im not sure. as you can see, the process changes. and Ive even checked it through run time, and each and every time, the process.processname changes.

I need to be able to find files in a folder where the extension can be either caps or small letters. Here's my code:
Code:
Public Function GetIcon(ByVal name As String) As Icon
Dim execAssembly As Reflection.Assembly = Reflection.Assembly.GetExecutingAssembly
Dim stream As System.IO.Stream =
[Code]....
How can I modify that function to return the file regardless of whether the extension is in caps or small letters?

I will have a directory of files (IFO, BUP, and VOB; DVD files for anyone who cares), I need to find the first one by sorting these like this: Filter out everything that does not have a .VOB in it, then find the one like this VTS_**_1.VOB. It will always have a "1" before the extension, but the two numbers before that change, lastly I need that file returned as a variable.

I've been doing a lot of coding latley and I'm interested in some things that vb can do. I was wondering if vb has the ability to search a directory for a file or mutipule files within a folder. Like in dos I can do C:user*.* and I can get all files that have . in them. Is there a similer way to do this in VB, I don't think VB has a wildcard or I've not heard that it does so I'm comfused on how I would find a file if I didn't know the path.

Is there a better way of finding the path of a file that was opened with the open file dialogue? This is what I did. It works, but it seems like there should be a way to get the path through one of the open dialogue options.
Code:
'm_PicSource = OpenFileDialog1.FileName
'm_PicSource is a global var
Dim strCnt As Integer = m_PicSource.Length - 1

I'm using VB.NET in Visual Studio 2008 in a Vista 64-bit OS. I'm trying to find an easy way (there must be one) to quickly retrieve from the registry the application file name and path to use in a Shell command to open a particular file. Specifically, I want the user in my app to be able to click on a PDF file and have the app open that PDF file using the application associated with PDF file types - Acrobat Reader, for example. Anyone have any suggestions as to proper coding & syntax for the following sequence?:
(1) Get name of .exe file associated with .pdf file type (most likely from the HKey Root Classes hive)
(2) Get path for the .exe file
(3) Shell("[pathname]appname.exe filename.pdf")
I've spent a couple of hours looking through the forums and haven't found what I'm looking for.

I am trying to trim the path from a filename. With the following code, it returns "My Documents" where I should be getting "Test.txt". if I change the 1 to a 4 I get what I'm looking for, but that's not going to work if I'm working with a file deeper into subdirectories. I need it to display the name of the file regardless of location or file type.

Using vb.net 2008 I have a form with a PDFViewer control. I pass the filename and path to open the pdf. When the form is closed, AcroRd32.exe is not destroyed. It remains in Task Manager even after I've completely closed the application. The more pdf files I open, the more memory used. How can I destroy? I've tried setting the control = nothing, ctrl.dispose but neither is working. What am I doing wrong?

This is the code I have set up to scan a directory of files:
Dim fileArray() As String
fileArray = Directory.GetFiles(System.AppDomain.CurrentDomain.BaseDirectory & "help")
And it successfully gets all files in the directory, but it gets their absolute paths as well. For example, one of the entries in fileArray() is:
F:ProjectProjectinx86Debughelpook_troubleshoot.html
And I want it to just be:
book_troubleshoot.html
Is there a way to do this without parsing through all the array entries to trim off the path?
