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 have a website that has highly granulised access and hence requires many web.config files. The problem is I would like to trim the menu so that only certain users will have access to certain folders. I have enabled trimming and setup roles in the sitemap, however when I access the page the menu is not show, as I am authorized to view the default page which is not in a subfolder. When I type the url of a page in sub folder's I have access.
How should I handle this:
A site map for each web.config file - don't know how this will work Removing the sub web.config file to only use a single one

I'm developing an application to help law enforcement retrieve and analyze logs and other files left by the use of Pidgin (a multi-protocol messenger client). Right now I'm nearly done, but I want to add the ability to search chat logs for user-defined words or phrases and I don't even know where to begin.
Chat logs are stored as html documents in a folder/sub-folder/sub-folder/sub-folder fashion, where each sub-folder can have dozens of sub-folders inside of it, and the final sub-folder can have dozens if not hundreds of chat logs. If anybody could point me in the right direction, I'd be very grateful.

View 7 RepliesI am writing an application which needs to allow the user to select and open document files as a new process, edit them, then when they've finished backup the changed files automatically. For example, start a .doc file within Word or a .xls file with Excel What I wanted to do was use process.start to run the application and store the ProcessID returned in an array so that when the process finished, I could check all the files that were using that application for changes.

View 2 RepliesI 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)?
View 13 RepliesI 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:

View 2 RepliesI'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file.

Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

I'm attempting to send an email to multiple recipients, via the System.Diagnostics.Process.Start() command. The string I'm using looks like this...
System.Diagnostics.Process.Start("mailto:Test1 <test@nowhere.atall>; Test2 <test2@nowhere.atall>;")
The first email shows up correctly in my email program (Windows Mail in this case), but the second email does not show up. If I get rid of the brackets that separate the email from the recipient name (getting rid of the recipient name from the string), then both email addresses will load without problems. It's only when the brackets are included that the problem occurs. I've tracked the specific problem spot to the closing bracket on the first email name. For some reason, everything that follows the closing bracket is ignored.
I'm using VB.Net to launch multiple command line window (same exe file) through Process.StartInfo. I would like to have those windows running at background without hanging main UI thread that launch them and at the same time able to get the output of those external window to show progress at progress bar.Here is a summary of what I'm trying to achieve but need further advise which way is feasible
- launch multiple exe command through Process.StartInfo
- don't want the external exe to hang my main UI thread
- need to get feedback from external exe to update progress bar which is placed at main UI thread
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):

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.

View 3 RepliesI have an issue in my project I am programming in both Matlab (Matlab2011a) and Visual Basic (VS2008).I've created a .exe file from my matlab code. It works well when I click on it with my mouse.But I need to run it within Visual Basic. I know it's possible to call .exe files with Shell() or Process.Start(), and it works well for files such as firefox.exe or notepad.exe. However, it doesn't work when I call my own .exe file ...It's weird because when I look to the Task Manager while trying to call it (within VB), I can see the process starting and ending, but its output doesn't appear.

Lets get down to it, Basically, I'm making a kind of "Anti-Hack" for a project I'm working on.The basis of the "Anti-Hack" is the check processes for names of known Memory Editors, For example, one memory editor I am scanning for is Cheat Engine.exe, I am using this code to scan for it, then I use the result to activate a different piece of code.
If Process.GetProcessesByName("Cheat Engine").Length = 0 The
'It's OK
Else
<Removed for obvious reasons>
End If
Basically, I don't want my code to look like a library of If statements when the only thing I am changing is the process name, what I want to do, is have an encrypted .dat file with an array or list of known tools. I want to then go through the array/list and keep checking for instances of them running.I know nothing of how to encrypt/decrypt .dat files through VB. (I'm not an expert at it atm )I am open to other ways (Easier ways) of doing this, like a Class with a list of names etc.
**NOTE** I would rather it be a separate file as the program features an Auto-Update feature, so it will be easier to update the list.
**IMPORTANT**Also, I would like to know how to hide my process, so it cant simply be ended, It may sound suspicious but people will be able to just close it and start hacking T_T, Unless there is another way, I would appreciate it (Like making it so it cant be ended etc.)**IMPORTANT.
Using windows xp. Sp3. over 100GB free on each disk that I use,Attempting to unzip a file that has directories in it. I want all files in the zip file to go to one directory ignoring the dir structure.I'm using VB to do this. Problem is that the process hangs at the same place on 2 different machines. Any ideas. Code below in vb and the results.Executing the same command line from DOS works correctly.unzips 72 files then hangs.
Code
newProc.StartInfo.UseShellExecute = False
newProc.StartInfo.CreateNoWindow = True
[code]....
Here's where it stops. And shows the dir struct of the zip file NDDF Plus DB. i've got a screen shot of the dir structure and files. basically it unzips the files in order of the dir structure and stops above.
I need to pass a file's name as an argument and a switch to the executable I'm using.I'm doing it like this:
vb.net
proc.StartInfo.Arguments = "-z ""C: est.txt"""
I'll know where the files are that I need to grab, but I won't always know the exact names. So, I thought I could grab a collection of the files, store them in a variable, and then pass them as an argument.I tested it with one file like this:
vb.net
Dim File As New System.IO.FileInfo("C:...Desktop est.txt") Dim proc As New Process proc.StartInfo.WorkingDirectory = "..." proc.StartInfo.FileName = "....exe" proc.StartInfo.Arguments = "-z" & File & "additional arugments" proc.Start() proc.WaitForExit()
But, as you all may already know, I can't use the & operator with a string and FileInfo.Would I have to then convert the FileInfo to a string first and then pass it through?
