VS 2008 : Communication Between .net Programs?
Jun 15, 2011
I have a Windows Form Application which has been developed in vb.net 3.5. It is a charting program and shows stock market charts to users. Now I have made another program in vb.net (same .net version) and I want this program to interact with the one I made before. The new program is like a small scripting language. So for example: if I run a script then its output should be reflected in the other program. How can the two programs communicate ? Both will be running on same systems. No remote stuff. I mean passing arrays,strings or possibly structures.
Plus I have several functions which are written in first program. Is it possible for the other program which is an .exe also to call the functions of the other one if I make sub/function public or something. The reason is we can calls functions or subs if we include a dll. But can one exe calls functions/sub of another exe (if both program are in .net).

I made a device (it's a remote-control your computer thing). Is it possible to interact with it using USB & VB.NET? If so, how? I've looked around and it doesn't seem to be part of the framework, but maybe there's some API I could use? I could always use serial ports, but I don't really want this device to require a battery. Is it possible, and if not, is there another way I could do this?

I am currently using the code from this thread:Click Here Using the code how would i allow the user through the client to send a message to the server which specifies the user the message is intended for as well as the message. I know how to send messages as there is a function for that in the code supplied in the link.Though how do i associate usernames with each client? As i saw a username property has been created in the code but how do i use it for the purposes i want?
I also need to be able to test the username and password fields for a login system..

I am sure this can be done, as Visual Studio is basically built this way. What I want to do is simply make a class that my other workmates can use. But rather than have it in a code form, I want to build it (partially), and then my workmate can add it into their programs (sort of, like the add reference for the .NET stuff).

I'm thinking of creating some applications that will process search and storage requirements.
I want these to be separate applications - so that I could eventually move them to different servers for scalability.
What methods are available for me to have these app's communicate with each other?

Question is related to rather simple programs typically presenting some data in a few datagridviews, charts etc. And consisting typically of a main form and one or two settings forms.I'm trying to program in a layered structure, pulling every bit of code out of any form class, and having a seperate "program class" for any form that I make. Now.. So far you can't complain on that I guess, but how to do this in best coding practice? In the form class I make a member object of the program class, hence making the program class a child of the form. Now I'm able to create events in the child class, and have handler methods in the form, without writing delegate classes (it seems). Now, that is fine, as it enables me to update the form controls with such events happening in the program class. However, how do I send events the other direction, from the form (parent) to the program class (child)? I guess I don't have to use events, I could just use the member object to access public methods in the program class directly, with passing of parameters from the form controls.. however, is that good practice? Or should I use events also that direction, and how to make that work, do I need to introduce delegate classes

I'm not sure what I have done wrong, I am trying to get my program to send data (UsernamesPasswords) from client to server, then the server says if it's right or wrong.
The error is on this line:
Dim networkStream As NetworkStream = TcpClient.GetStream()
Heres the Client:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
If TextBox1.Text = "" Then
MsgBox("You must enter UN/PW!")

I am working on a porject that interlinks a PC and PIC using the USBtoUART programmer for Serial Communication.
I have just started using and reading the Book on Visual Basic 2008 Professional and read the book by ROD STEPHENS <VB 2008> Programmer's Reference.
However, I would like to know where should I start working from?
I personally want to start from building the Visual Basic interface that enables serial communication between PC and the USBtoUART converter.

I started with VB 6.0 back when i was 14, I was mostly into coding programs that interacted with other programs. Recently I installed VB.net 2005 pro i got from school, and i grabbed few source codes that teach show interaction, I feel so dumb, i dont remember anything lol. It be great if you guys can share some source codes and other stuff in this field. also other day i was in dream spark and i am able to get copy of VS.net 2010 ultimate edition, are there a lot of major changes, cause i got 2 thick book for VB.net 2005..

When you've finished a program and you're trying to distribute it to the mass public. How is the best way to go about doing this? What sites would you post your program on and getting the word out that there is a new program on the block and it does xyz. This is directed to freeware so there wouldn't be any advertising.
Sorry for not explaining it very well the first time.

the only way I can get reading from an instrument is through proprietary software. even though it is connected with USB. the instrument - a Cary 500, with a GPIB interface.the problem is with instrument commands, like "reset" or "change wavelength" or "instrument reading" They reside inside a primitive Basic shell provided by the instrument software. I'm looking at expencive National Instruments, is there another solution with VS/NET?

They are all working on my computer,but they are not working on any other computer(I tested it on about 10 computers). They are working when i start making it,but after they are not working. When i try to run it on other computer it is not opening(there is not any error message), or there is a crash report(application crashes). So they are working on beginning of programming, and after they aren't.

I will do a program then save it and close it out but when I go back to open it it won't open. It just sits there. I'll click on Recent Projects and they won't open. I'll click on Open Project and select a existing file and it will just put it in Recent Projects but won't open it up.

I'd like to mention that getting a list of the installed programs via the registry is not a viable way to receive a full an accurate list. The two main areas where the programs in the registry are stored, are mainly MS programs. Some manufacturers put their keys here as well, but most don't. And since it's impossible to know where the manufacturer has stored the key, let alone the name of the key that would give the list and the uninstall capability, it's not ideal to use the registry.
That being said, I was told that there is a COM API that Microsoft has made and uses in the Windows OS and was hoping someone knew what that API is and how to maybe implement it in VB.

This question may be vague but I was wondering if anyone has ever implemented an application that basically creates a UI to list and monitor all running applications you have running. This applies to many developers who might have multiple programs running continuously and it would be great to have an app that monitors these programs..or does anyone think it is just unnecessary.

First of all, Hi to everyone, I'm new here..I'm currently investigating a way of doing the following and seem to be coming up with dead-ends!I am trying to create a windows service that sits in the background waiting for programs to be started. When the programs start I want to be able to check a unique bit of information for each program (I believe GUIDs may provide this) to see what the program is. If the program is not allowed, I aim to provide a warning to the user and possibly close the program. The aim of the application is to identify when users are attempting to install additional software on to the computer so simply monitoring for a certain executable wouldn't work as msiexec is called for all MSI's and as I only want to stop blacklisted programs...this wouldnt work.

I'm planning to make multiple projects, which could connect (or comminicate) together. It's like a designing Network Program. There'll be a main program and some sub programs. These sub programs will send the informations about other computers which is on my network to the main program. If you ask "Why do you need to get infos about other computers?" ,then let me explain. I'm using limited internet connection and I'm not the only one who's using this wireless network. If I get over the limit, I'm paying some limit-upper fee. So, I've to control others internet usage to not to get over the limit. I've just made a small download counter program for my pc, but as I said, I want to convert it to a bigger project, with network solution. Could anyone refer me any resource, or show me any starting point?
