I've got a curious problem that I can't crack. I have 2 applications, app A and app B. Application A runs continuously doing various things. On the same machine I have application B that runs infrequently at random. I need for application B to tell application A to do something. Both are vb.net apps that I've written and can tweak to make this work. I can't figure out how to get app B to communicate with app A while app A is already running?
I'm trying to use a cell phone modem to send an sms message but i'm not sure whats wrong with my code?? Also i'm getting en error with _ContsSMS = False .. but i have no idea what that line is ? (Also are AT commands not used for Windows 7, is this why it wont work?)
Using COM7 As IO.Ports.SerialPort = _ My.Computer.Ports.OpenSerialPort("COM7") 'set command message format to text mode(1)
i am making an app for my media server, but now i ran into a little problem. Once i press pause on my app, i want it to pause my VLC player. One way is to press Space bar in VLC. Is there any way to send the Space bar key to VLC? (or is this not possible in VB.net, If not: witch coding language should i use?)
Just wondering what is the simplest way to send data between ALL instances of my app on the SAME windows login on a single machine - I do not want to use anything that opens a port as i don't want there to be any chance of having it blocked by a firewall
In my program I am using a MySQL database and I want to allow users to send each other messages ("Emails"). How can I go about something like this? I'm not wanting someone to do my 'homework'
I need to send string messages between applications (many clients and one server). When I tried using PostMessage/WndProc, then my message got split up in strange portions [URL]. So that was a no go.Second I tried using Pipes, but couldn't make it work with multiple clients.Third I tried using TCPIP, but couldn't make that work too.
I used to send small messages to users on a network through "SendMessage" under the user tab of the task manager. Now I have 2 virtual servers where users connect through remote desktop sessions, and I can no longer send messages to all users this way. Therefore I wanted to put this function in a application.
I want to send an SMS message to many people. I have the person type and phone number for each person in a MySQL table. Using a stored procedure, I am calling a stored procedure in the database to get a list of phone numbers for all the people of a particular type and store it in a DataTable object. I have one URL that I need to use to send all the messages for all the people of that same type. The variable s in the below code is the person type which comes from a drop-down control[code]...
How do I loop through the resulting DataTable and send the SMS message to each one using the URL? The variable dt has the list of phone numbers for the people who match the type stored in s. Please help me solve this problem. I am new to VB.NET.
I have never programmed a network program before and would like to learn at my own pace. Also I am not asking anyone to write this complete program for me, just bits of code to help me write a complete program. (though if you do code it all I won't complain.) I already tried using internet tutorials but none of them seem to work.I am trying to program a simple form with 4 buttons, and 2 users.The first button is a connectivity button. "Green" for connected, "Red" for not.The second button is a "Connect" Button which will connect to another computer with this program installed/active. (I want it as simple as possible)and the next 2 buttons switch between "1" and "0" depending on user input(Default "0"). the first button is the local user button and the second is the remote user button. When the local user clicks the local button then what he/she changes it to will be displayed at the remote site. The same thing will happen with the remote user.
I know how to place all the buttons where they belong, and to change the local text, but I have no Idea how to connect to a remote program or to pass messages between the two users. Can anyone suggest some Simple code to do this. (something that I will be able to learn and use to make more complex code later on.)
I have downloaded the vb script and it works as it should, its a program where you have some buttons so that you could trigger the relays.But i need several small scripts, one for each relay on / off so that i can call them from a .bat file with argument.i have a .bat named relaycard and in thet i have created argument like
relay1on relay1off relay2on relay2off and so on.
The small program relay1on should just do the jobb and then close itself.Maybe its a little bit clearer now.On the link that i posted there is a manual and even links to the vb program,
What I have done so far is place the compiler inside the bin of my project folder, inside the Debug folder. I managed to call the cmd shell but the problem is whenever I pass commands to that cmd shell, it doesn't work. What happens is it opens a cmd shell and when I pass commands on it, it opens many other shells.[code]...
I need to be able to send keycode keys.apps (windows context menu key) to an application. Surely if I can detect the keypress, there's a way to send the keypress, right?
What I'm doing is having a 3rd party app save a screenshot and the only way to have it do so is through its right click context menu.
i've been wanting to do this for a few years now and it amazes me that no one can come up with a solution.i want to write a program (preferably in vb.net) that can send a message to another computer (or device) that is connected to the same network as me. I want the message to appear on the other computer (or device) in a popup message box. Also, it would be ideal if this could be done through some sort of bluetooth connection, if not then local ip connection will do. I don't know how i would go about doing this but i know it's possible because i've seen some programs do it... in fact i've seen a program called blackrain that without any additional software installed, can display messages on an ipod touch screen to instruct the yser what to do, and then display the results from their input on the computer screen, almost instantly. I would like to know how that works as well if anyone has any thoughts please feel free to share them!
We are upgrading a suite of data acquisition and analysis routines from VB6 programs to a mixture of VB.NET, VB6, and Matlab programs. We want to keep the system modular (separate EXEs) so we can easily create specialized stand-alone analysis programs without having to constantly upgrade one massive application. We have used MBInterProcess to send messages between EXEs when all the programs were written in VB6 and this worked perfectly for us (e.g., to have the data acquisition EXE send the latest file name to a stand-alone data display program). Unfortunately, this ActiveX cannot be used within Matlab or VB.NET to receive messages. We are wondering what is the simplest string message passing system (pipes, registered messages, etc) that we could adopt. Right now we are just polling to see if new file was written in a specific folder, which can't be the best solution. Our ideal solution would not require a huge investment in time learning nuances of Windows (we are biologists, not full-time programmers) and would work in both WinXP and 64-bit versions of Windows.
In response to the queries, we have wrapped the entire Matlab session within a VB6 program that has the MBInterProcess ActiveX control. That works but is not a great solution for us since it will probably lock us into WinXP forever (and certainly will prevent us from using the 64-bit version of Matlab). The latest version of Matlab (2009a) can access .NET functions directly, so we assume one solution might be to use the .NET library to implement pipes (or something similar) across programs. We would like to recreate the elegantly simple syntax of the MBInterProcess ActiveX and have a piece of code that listens for a message with that program's top-level Windows name, and then call a specific Matlab m-file, or VB.NET function, with the string data (e.g., file name) as an argument.
I have the following issue: i want to make a vb .net application that can send any string message to any other application opened in windows(more specifically to an application created in visual c++ 6.0). To tackle the problem i firstly created 2 forms in my project and tried to send a message from one to the other. I have tried 2 ways[code]...
I am currently making an app in visual basic that I plan to make a chat server. I know that somehow I'm going to get the program to send and recieve data across ports on a certain ip address with variables such as maximum connections, etc.
The part I am mostly stuck on is firstly the code that you would need, or how to make a function to interact with ports across an ip.
Secondly, would it be a good idea to make a backround service to run for it to work on a host, and also how the other computers are going to find a host.
I need to send commands from PC to device through USB cable, and the code is : "0"(48) and must end with Enter(13). so what should I type in for the code for Enter?
In my application I have only one button . That button will open CMD then it will send a command into cmd , now after that command it requires an "enter key" to continue the process .I tried the shell command in order to access the command but then I couldn't press enter in cmd using my application
I am trying to send commands to Command prompt.The following code should open the text file I specified.However it opens several instances of the cmd window and also several copies of the text file. Sometimes the text file is not opened and if the file path is long, part of the file path gets inserted into my text file.[code]

I'm running Visual Studio 2010, and i'm trying to use AT commands to send an SMS. My question is will it not work with windows 7 due the exclusion of hyperterminal in windows 7. (I was able to dowload a version of Hyperterminal and can use AT commands in that.. but my code itself does not work.) My code is below.
I have an application which I would like to access from another computer.So I thought of making a client which my application(server) would send commands to and then the client runs the command.
I am making a program where you can send text messages to people. And as you can see I ran into a problem. I am trying to load everything from text boxes because I want everyone to be able to use it. So dose anyone know how to fix my code? [code] When I run this it says it dose not work and it says it needs to load properly.
Is it possible to send window messages from one computer to another through Dot Net 2008.suppose i have 2 computers on a domain, now i want to send message from one computer to another.
