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 library that interacts with our phone system, ie, Hey phone, call this number for me. This library is used in one of our in house products. I would like to put this instead in a service, so that any of our in house products can send the service a message to place a phone call. So basically I want to communicate from a program built in .Net 3.5 with a service running on the same machine also built in the 3.5 framework. I have done some work with WCF and was considering using this but thought I would ask what others have done or would do.
View 4 RepliesI am trying to create a program that downloads audio files via FTP, converts the audio to mp2 if necessary and copies them to a certain directory for consumption by our automation system. (I am a radio station engineer.)I am using the open source converter FFMpeg to convert audio files to mp2. This is a command line exectuted program. Here is the command line that I use to execute the external program with the input and output audio files at the root level: cmd.exe /k ""C:New Folderffmpeg.exe" -i "C:Test.mp3" -y "C:Test.mp2"" This command line works correctly whether I am using Shell() or System.Diagnostics.Process (Process) to execute the external program. I am going the Process route so I can know when the conversion has finished.Now, I really don't want to use the root directory for this but when I go below root with this line using Process the external program will not execute:[code]Can anyone tell me why that line will not work with Process though it works as expected with Shell()? I can't figure out how to stop the external program to get some feedback as to what its problem is.

I chose Visual Basic 8 as a computer interface to communicate through RS232 (serial) to my microcontroller, which in turn will do its own thing to transmit data it receives from the VB GUI through wireless
I have used VB before but it's been a long time. I looked at some of the settings and it looks like it has a SerialPort com component I can use. Will it suffice for this project?Might be a simple question, but just want some tips from experienced developers.

I have a program that starts another program after setting the regkeys basically the program continually syncs the calandar of outlook and another application.I set the regkeys than launch the c:sync.exe app. I have tried a simple process.start and launching the process as a thread and they both do the same thing: The other process starts and works as it should but my main program goes "White screen" or "not responding" until the process.start has exited.
I want the process.start to run in the background so if users click in my main app it responds and truly that they can access the context menu of my main app from the taskbar while the process.start is running.

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:
Private fsFile As Scripting.File

I am currently working on a program that will paste text into a second program. The text will paste into several different fields automatically.
The problem I am running into is that I need my program to check for running processes(as the second app will already be running). I seem to have done this just fine. When I then need to "use" that process
I use myprocess.start()
This of course starts a second instance of the application in question.
How do I basically use a process that is running as if I used the command .start()?
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 have VB project and I tried to use PUBLISH feature.It seems to create nicely some kind of setup program, but the setup program does not ask where to copy files (it does not seem to copy filesto target machine "PROGRAM FILES".)Is this setup program somehow different from usual installers?

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.

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.

Having a slight permission problem with Win 7 I am guessing it will be the same on Vista but work fine on XP (yet to try)But my program is sitting in: C:Program FilesCompanyProgram And its trying to create new files alongside itself in the Program Files area but bombing out which I know is permissions. If I go there to create the file myself it comes up with a UAC prompt and when I hit allow it works fine but obv the program can't do that byiteslf so bombs out.Is there anyway I can over come that without the user having to grant admin rights to the program each time it starts or do I have to write data to another place?
