I have a few questions regarding getting information from other programs.
For instance, once i launch a console application i want my other program to read it's output. If my build.exe reads whats printed in cmd.exe and then outputs it live on a textbox <--- How do i do that?/Is it possible? Im sure it is. And then i want to know how much % of CPU is used by the program and how much memory are used.
I'm wanting to transfer data between two programs. Basically, I have one program which is the "monitor" program. It opens another program and will fill a textbox in said program and then click a button on the program. When everything is done after clicking the button, the program will need to send something back to the monitor to tell it to close the program and open up another one to start the process over again.
View 4 RepliesI currently have two programs that need to comunicate one with another. It doesn't have to be something complicated, it's just passing data from one to another, all very simple. I was thinking of using .net remoting, but I've heard there's a new thing WCF. Should I go for the .net remoting or try WCF? Or is there something simpler to use?
edit: Both applications are simple, I don't want to have anything to do with IIS, services and such.
I have created a program that takes a users input of a bunch of fields. Now what i want to do is create a word document using the information that was entered so users can print a page with the information and save it as well.
View 1 RepliesI 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).
View 4 RepliesI 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..

Sorry for not explaining it very well the first time.
The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal hKey As Long, ByVal _
lpSubKey As String, phkResult As Long) As Long
Goal: Find information on how to implement a method which will check if a certain DSN exists, and then if it does, extract the information and use the information for connection purposes.
I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this. And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working?
Private Sub txtDestPayRate1_KeyDown1(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtDestPayRate1.KeyDown
If e.KeyCode = Keys.Enter Then

I am designing a backup/restore utility for work.atm i have been able to populate field for PC name, IP address, MAC address, number of printers installed on the PC but i am wondering is it possble to get all the printer information 'with the click of a button' to print all information like the prnmngr.vbs script down.I am able to run a batch file but i wanna get it to go from that app or even embed to batch file to the app and run it form there .
View 4 RepliesI am using VB2005 and trying to put an application together.What it needs to do is retrieve information from a binary file, possibly alter that information, and put it back into a new file.The file is a .wav file with data appened to the end. There is an additional section at the end of the .wav file which stores xml data.I have found that if I open this in a hex editor and make a 1:1 swap on any of the bytes that the application that the file is for can still read the XML.If I tried to add or remove characters from the XML then it would not read. I located a header byte and incremented it to resolve this.
This worked as an excellent bandage to do conversions where the data always needed to be changed to the same thing.What I have been asked to do is build logic that allows for different things to happen depending upon what data is contained within the file.The method that I am currently trying to impliment is:
Read through the file with a system.io.binaryreader
Searche for a bytestream that will signal data is coming
For example:
If System.IO.File.Exists("C: est estread.wav") Then
Dim findit() As Integer = New Integer() {&H3C, &H55, &H73, &H72, &H44, &H65, &H66, &H30, &H31, &H30}
Dim i As Integer[code].....
And then extract all the data till the end of element marker "<" It seemed like there should be a better way and I was looking for some insight. If I proceed with this method, I will have to read the file one time to gather the information and then a second time to write it all out with the header modified for length.This is my first experiene with working with binary files in this way.Also,I've been experiementing with building a string and slapping it back in at the end using the binarywriter.write(string) method.I noticed that it was putting in header characters before the string.These seem to change if I change the length of the string.At one point it was d0 07. Later it became e7 07. Does anyone know of a way to prevent this header from being inserted?
I tried a for each loop to grab all of the characters from the string, convert them to a byte array and deposit the byte array into the file, but the header remained the same. When I write the byte array generated from a system.io.binaryreader I do not get this header.
I have a fair bit of experience with VB.NET and C# (In this case I chose VB.NET, blame my laziness), but I do most of my professional work using PHP. I have no experience what so ever in using any database with VB.NET let alone MySQL.Just FYI, at the moment I am only trying to Query the database to gather the information required to activate. The Activation wizard and algorithm building (which is finished anyway), and everything else will come soon. I chose the MySQL database because I have experience with it, and it seems the best option for remote usage.The whole idea already works in PHP, I'm just have major issues moving it accross into VB.NET (Using the MySQL Connector.NET);I understand the basics, and all I need to know how to do is Count Rows and gain access to the other information in a row based on provoided information (in PHP, through mysql_ result)
So, here goes nothing, this is the Query code I am using in PHP to complete the job I want to do in VB.NET. [code] As you can see, I basically need to get the PHP code into VB.NET to fit into the 'btnQueryDB.Click' Command in VB.NET. By Equivalent, the Product ID in VB.NET will come from 'txtPID' and similar, Serial Number will come from txtSNUM. Once counted to be 1, the Activation Code and Status will be fed into 2 other text boxes in the form. (acCode, and acStatus).
Im building a OS and i need ideas for programs to put in it.
View 3 RepliesI've spent the best part of the week learning about TCP/IP and sockets but it's really draining my enthusiasm for my project. The basics are simple enough and the MSDN examples are fine and I can put together a simple server/client easily now, but once I start getting into asynchronous connections, threading and all the other stuff, I'm getting bogged down and frustrated. I've followed a dozen tutorials and examples now and they're all too confusing and half of them simply don't work.
I think what's most frustrating is that I really don't wish to become an expert on sockets or TCP, which seems to be the advice on most forum replies. I really want to be getting on with my project which has ground to a halt since I started looking into this. Yes, I know the world isn't always that simple.
So, what I'm looking for is a 3rd party app or some working code that will let me set up a server and multiple clients. All I really want them to be able to do is to send strings to each other, without blocking the application. Really, that's it, just the ability to pass strings back and forth between server and client, preferably in as simple a format as possible - e.g SendMessage(Client,String).

Is it possible to link two programs with each other. Like one that can control the other one. Because Ive got a cousin and he is living too far away. I created an application that should do his work on his computer, but the application needs to be controlled by someone,.. and he kinda cant do it. So I want to make a second application to control the application that is on his computer.
For example. If I click on button1. The application on his computer clicks on button1 too.
how i would run a program from my application that is in the same folder as my application. E.g C:\install.exe path would not work as each user would have to have this in there c:\ drive for it to run. Rather i want them to be able to click my exe from a network folder, which installs the programs which reside in the same folder.
Dim ExecutablePath As String
ExecutablePath = Path.Combine(Application.StartupPath, (c:\Install\Programs\setup.exe")

Basically i want to run my exe, once install is clicked the program finds the install directories in the same folder rather than C

View 1 RepliesI'm working on a program, just to learn a bit more about programming. The program's function (if I manage to do it) will be to accept drag/drop files and create a link to them within the program itself. For example: I drag and drop the .exe to a game I have installed; the program then creates a shortcut within itself; the shortcut is displayed in the program with the name/icon; if I click the icon within the program, game launches.I've already manually coded something to this same effect, but it doesn't automatically add new shortcuts/buttons so I have to keep going back in and reprogramming another button every time I install a new game/program. I'd like to be able to just drag/drop and be ready to go. Any ideas on how I can get this function? I'm using Microsoft Visual Studio 2010.
