Process Files By Extension??
Sep 14, 2010
I have a program that processes files in a special subdirectory and the program processes the files based upon the "Type", i.e., "Text Document". If an application, such as a text editor, installed onto the system, the "Type" may change to suit that application. For example, I recently had one change the type from "TXT File" to "UltraEdit Document (.txt}". Yes, the squirrely brace was on the end, don't know why. Well, after this app was installed, my program found no files of "TXT File" type to process even though the subdirectory was full of filename.txt files.
So, how can I get the code to look at the file extension, not the Type? A few lines of the code are shown:
Private fsFile As Scripting.File

I am using VB 08 running an openfiledialogue wanting to get the result of the GDS file (*.gds) to be the default extension at the drop down menu instead of All file when the openfiledialogue box opens.
I coded it with:
OpenFileDialogue.Filter = "GDS File(*.gds)|*.gds|All files|*.*"
but the results i get in the open file dialogue box remains as all files being in the drop down menu as the default file extension. How to i set it to ".gds" format?

I'm at present looking at various ways on how to convert files without any extension and making them with a .txt extension. At present, I'm using the RENAME feature within windows to do this, but i takes time when there are a lot of files to rename. Can anybody give me a few pointers on how this can be done using Visual Basic?

I have to read SGI Files (I belive it's Suns Raster Image files, they have .rgb extension,but contains no header information), scale it, rotate it and maybe apply anti-aliasing filter to resampled image.I am just trying to read the image file. I read the file in byte array using FileStream and trying to display it in a image box, but it is throwing error while creating Bitmap class from the byte array. My code looks like this:
csharp
string imgpath = "Images\sample1_400x400.rgb";
System.IO.FileStream fs = System.IO.File.OpenRead(imgpath);

i have been trying to search a specified directory and all sub directories for all files that have the specified file extension. However the inbuilt command is useless as it errors up and dies if you dont have access to a directory.
Private Function dirSearch(ByVal path As String, Optional ByVal searchpattern As String = ".exe") As String()
Dim di As New DirectoryInfo(path)
Dim fi As FileInfo
[code]......
However i get an "System.NullReferenceException: Object reference not set to an instance of an object." when i try to access the data stored inside the filelist string array.

Why would I use an extension method instead of just creating non-extension sub or function?
For ex, I could have an extension function called IsNullOrEmptyOrAllSpaces on String, which does a check as its name implies. Or I can write a stand alone function that does the same thing. Other than having the extension show up in Intellisense, is there any advantage? Is a call to the extension quicker/more efficient than a call to a regular function?

I am writing a manager for an app that we use at the office. I have successfully written launching, monitoring, and managing number of instances using the process class.Each file is the data output for one study. Each of the 2-8 instances of the application will run 1000 studies overnight. The fault would be that the file stops growing. I cannot just check for that, because it also stops growing when it done with one study. I need to be able to determine which files are being written by which threads (or vis-versa where i know which files are 'running' and need to see who owns them)?

If i have an extension ... say...
vb
<System.Runtime.CompilerServices.Extension()> _
Public Sub Invert(ByVal b As Bitmap)
is there any way of hiding this from inteli-sense if it is not used as an extension?so that pressing ctl+space only triggers it if you go "bitmap.Inve.." rather than prompting on "Inve..."?

I was wondering about something: is there a way to communicate with another program/process on the PC without using files? What would this look like? Is there a search term I can use to get more info? This is not a vb.net question per se, but a general software question.

I have a process of copying files from one path to other in my application. The problem that I am facing is, when the copy process starts. my application will be busy for that amount of time and cant do any work. So I want to make this copy process to be in background as a separate process without making the application to hang.

I have a Windows service that is watching a folder for files that will be placed there.(Created in Visual Studio 2005.)The files each represent a transaction, and the transactions have to be kept in order.As I process each file (transaction), I want to forward it to someone else.(The someone else wants them kept in order.)It looks like I can't paste multiple files into a folder simultaneously and still be sure that they will be processed in the order of the original date and time they were created.Nor can I be sure that they would be read in name order.(FileSystemWatcher would grab them in any old order it chose.)So I think I will have to move the files into the folder one at a time, in the proper sequence.But I'm wondering if I could get into a "racing" situation.
When FileSystemWatcher detects a file in a folder, it creates a new thread for your event handler to operate on.If it detects a second file while still processing the first file, would it then create yet another thread?If that is the case, then if File1.xml takes longer to process than File2.xml, it seems like File2.xml might finish first, resulting in my transactions getting out of order.In my own experiments,I have not seen evidence that multiple files are really processed simultaneously.I write messages to a log file as I process each transaction, and I never see messages from File1.xml's processing intermingled with File2.xml's messages.This seems to be true even when I paste both files into the folder simultaneously.it only keeps one event-handling thread going at a time, and queues up the events as they come, processing them on that single thread.Otherwise, I'll have to do something to ensure they are kept in order.

I'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET):
[Code]...
I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file.
