Use (.exe) Tool In Other Machines
Oct 13, 2008
i have created a tool written in C# that would parse string (from 3 files) using regular expressions then throw all the matches in a grid. It works fine on my machine.. It returns matches from those 3 input files.. The problem is when i use that tool (.exe) in other machines..there are no errors. The program works fine for the first 2 files.. but doesn't return matches on the 3rd file.I tried copying the codes in one of the machines just to trace the problem, but when i run the program, it suddenly worked fine.. from then, the program is working fine on that machine.

I have developed an application is VS2010 ( VB app using .NET4 ) ... the application runs fine under Windows 7 and on (3) XP machines we have here. Had one user looking for support on an XP machine ... when he started the app nothing happened. No errors or anything, just nothing happened. Had him install the latest .NET4 framework and everything was fine.
Just had another support issue ... user with the same complaint ... had him install latest .NET4 ... but this time did not fix the issue ... still nothing happens when he clicks to start the app ... no errors ... just nothing happens.
I can't check this because it runs on all our XP machines .... Is the only criteria that .NET4 be installed? I created an install that includes only the EXE from the BINRELEASE folder ... nothing else. Do I need anything else. Strange that it works on all our XP machines.

I have a small form program that is basically an interface for installing different software packages so that we can distribute a CD with our products that our customers can just pop in the drive, autorun, and click the button to install what they need. The problem that I am running into is unlike when I had built this same program in VB6, the program rewritten in VB.net will not run on some machines, and shows me an error: .net Framework initialization error. required version of .net framework v2.0.50727.
I realize that it is asking for that version of .net framework in order to run, but what I would really like to know is if there is a way to make my exe non-dependant on this so that it will run on any machine. Requiring my customers to install .net framework in order to access an interface designed just to idiotproof the installation of some setup files and provide easy access to a few pdf's really would just defeat the purpose.

I have two machines, on the first of which I have developed my application to a point of satisfactory stability. Now I want to move everything to my second machine.Both computers have the same level of XP and NET Framework code, and both have Visual Studio 2010 at the same level.I copied my application's project folder onto the second machine, but the second machine's VS 10 can't load the project because it can't find a couple of Interop files (e.g., AxMSComCtl2). All of files are present in the project folder and also in its.bin subfolder. The only observable difference between the two machines is the presence, on the first machine, of some Assemblies stored under my user name there. Copying the Assemblies to the second machine didn't help (I hadn't thought it would).Is my application permanently "imprinted" on my first computer, or is there a simple way of resusitating its clone?

Basically i have designed an app that runs smoothly on my desktop PC (3GHz processor, 2GB RAM, Windows XP Media Centre (SP3)).
When i put the app on my laptop(1.4GHz processor, 448MB RAM, Windows XP Home Edition (SP2)) it runs really slow and is unusable.
I have tried deploying the app and also just copy the whole folder to my laptop and run the apps *.exe from the bin/debug folder, but it has the same results.
I have tested it on higher spec machines with 2GB RAM and they also replicate the slowness, so i'm at a loss as to why it behaves 100% on my desktop PC, where i have Visual Studio installed but not on any other machine.
My question is if little differences like operating system, RAM, service packs, VS installation, etc, make apps run differently on different machines.

I updated a VB.NET application from Visual Studio 2008 to Visual Studio 2010 and made a few changes to it. Now it works fine on my development workstation but when the user tries to run it, it fails. The error detail is below. I've searched for System.InvalidOperationException and found several suggestions but none of them have helped. There isn't any static initialization code in the application. I changed the compilation to x86 instead of AnyCpu. None of these has helped. The project is compiled for .NET 3.5 and that hasn't changed. Both environments are Windows 7 64-bit.
Does anyone have a suggestion as to how I might determine what is causing this?

I'm focusing on Networking programming and I had found something that was very interesting to me in Remoting, which is the ability to have some how a "shared global variable accross applications" ... Here's a quick example of what I'm saying (which is stripped and modified from one found example on internet):
In the Remoting class:
Code:Namespace remoteclass Public Class xx Inherits MarshalByRefObject
Public Shared_Var As String 'This is our share variable
End ClassEnd Namespace
[Code]....
I found that I can eaisly use this red-marked variable (Shared_Var) acrross all application clients without any extra line of code to update its value ... without using even what is called "singlecall" and "sigletron".
But I have concerns:
1) This is only applicable for simple types of variables (e.g. string and integer) but an array or DataTable for example are not updated! and I don't know why!!
2) Would that load the communication network (I mean the content of these shared variables (few KBs to 1MB) will always be communicated across machines all the time without any management) ... Actually I don't how this works from inside, Does it update on change or cyclic ...
3) And finally, can I found something like this in WCF?

I have an object with a GUI interface. This has properties and methods. When this object is modified by anyone, on any machine, all other users should reflect the change, without specifically asking for a refresh. How can I achieve this? Imagine that the Object is static across users. I need complete details on going about it

I have a list of machines, 1 per line in a file called devices.txt.
What I need to be able to do is to ping each of these machines, and then output each machine that is online to another text file called machines.txt
The files need to just be the machine name and have 1 machine per line.

I have a ASP.Net Web application hosted on a server. I want to restrict same user to login on different machines over the network connection but with certain conditions to be satisfied. So I thought of adding three new columns to the User table so that we can track if same user is logged in on same or different machines.
Those columns are like :
IsLoggedIn : To check if the particular user is already logged in or not.
SessionID : To check if the same user instance is opened.
IPAddress : To check if the same user is on same or different PCs.
This should satisfy some of the below conditions, but it fails to satisfy some of them. Conditions are as follows :
Both computers are on the same LAN.
Each computer is accessing the application over the internet from different locations.
Each computer is accessing the application over the internet from the same location.
Some of the application hosted which means that IP address alone is not sufficient to distinguish different computers.
Some users just close the browser without logging out. So sessions may not be ended at this situation.
How to accomplish all these conditions to satisfy with my application ?
Mainly 4th and the 5th .

This question is about deploying a VB6 application that uses an interop component created in VB.NET, specifically, a .NET dll.Using Regasm.exe, I was able to create a .tlb and use it on the dev machine to add a reference to the VB6 project, but how do I go about deploying on client machines, particularly the .NET component?

I'm having trouble with program I'm writing for work. It's basically a GUI for some remote management scripts I wrote a while back.I have a listbox (listbox1) to which loads a list of computers from active directory, which works perfectly and quickly.The problem is that I also want to add to another listbox (listbox2) a list of machines 'currently active' on the network. I can't see an easy way to do this in .net but came up with a logical solution.Basically my thought was to 'ping' all of the machines in the directory listing and use the results to make the list...

Is there any better way of copying an application so I would have included all kind of things like the right references? I need to copy this big and ambitious application in order to work with it on different machines. Because all I got is errors that I cant get rid of, and it does not build the application, so I can't work on it. I was trying to reference the right components, it lessens the errors but still no chance to run the app.
Thats the link where I posted the errors: [URL]

The first user modified and saved the record and after some times another saved the data without modified or modifed some other columns. Now the last user who modifed the record contains the old data.

I am working on maintaining someone else's code that is using multithreading, via two methods:
1: ThreadPool.QueueUserWorkItem(New WaitCallback(AddressOf ReadData), objUpdateItem)
2: Dim aThread As New Thread(AddressOf LoadCache) aThread.Start()
However, on a dual core machine, I am only getting 50% CPU utlilization, and on a dual core with hyperthreadin enabled machine, I am only getting 25% CPU utilization. Obviously threading is extremely complicated, but this behaviour would seem to indicate that I am not understanding some simple fundamental fact?
[code]...
And this is occurring in a recursive function, so the QueueUserWorkItem can be executing multiple times, which in turn then executes exactly one new thread via the aThread.Start
Hopefully that gives a decent idea of how things are happening. under this scenario, should this not theoretically pin both cores, rather than maxing out at 100% on one core, while the other core is essentially idle?
