is there as simple way to pass data between 2 apps? it seems DDE support this, but vb.net 2010 seems not support DDE anymore. in my program, I need launch another exe, then wait the exe finish, and get the export data.
both apps are in the same solution. one method I can think of is: writing the data into a xml file, then load it from the main exe when the second exe is done.is there an easier way to do this?
Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController

I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.
i have a sample code written in VB6 that allows communicating between different application windows and passes data. The link is below:[URL] I wonder how we can do the similar work inside VB.net. I simply claim a method between different applications communicating each other and transmits data. Lately i was using the old code and after my researchs on internet i also found different methods using System.Runtime.Remoting libraries

View 2 RepliesWe are about to have a situation where our application needs to accept/give data to another application. Both applications are residing on the same machine.Two approaches being talked about are using a local web service that will do this or using files that will be used to share all of this data.
View 3 RepliesI had a user ask me today if I could make it so they could simply drag and drop text from other programs into the app I've written. I found an old (2002 & 2003) article on drag and drop, but I'm sure things have been made better since then.
Anyone doing this today can point me in the right direction? Is this much of a pain to enable?
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.

View 3 RepliesI'm finishing up an app for work that will work hand in hand with another app.
What I'd really like to do, is setup a method to add a button to the other apps border. So all they have to do is click that button when in that other app, do their business and move on.
Now, if I hadn't seen it before, I most certainly would've thought that this wouldn't be possible. But I've seen TeamViewer do it.
In that image, TeamViewer created a two-way arrow button and when clicked, displays a small panel of some sort with additional options.
I'm 99.99% sure I'll have to use Windows APIs, but I'm not sure where to begin.
How do i start a Game or an other application in a Panel??

If so, how?I know; Windows Forms based apps,console apps,DLL _ Class Library Projectsand I've had an introduction to ASP.Net.What I mostly want to know is, if WPF apps are for Silverlight then do they also run in a server based fashion like anASP.NET website would when you create ASP.Net webpages?Is it a way of creating what looks like a FORMS BASED application but it runs in a browser instead or what?Please enlighten me a bit further as I have no idea what WPF is all about.

View 1 RepliesI have some code that works in winforms, but not in WPF apparently, the code is as follows: This is set globally:
Private Property avar As Object

Thing is, the next window doesn't pick up this variable, so how can I make it recognise and use it?

Is it possible to change settings in other forms by another piece of software like if there was a flag = True and I wanted to change it to flag = False or instead of loading Dim processorID As String = String.Empty I can input Dim processorID As String = 1234

I have two VB projects in one VS2010 solution. The first program brings in about 60 integers every few seconds from my PC's serial port. The second program, published via Click-Once and running on my customer's PC, needs to see that new data every two to five seconds.
Is there a simple and reliable way to accomplish this, staying with VB? WCF is way over my head.
I am developing an application for internal use in our company. The purpose of this application is for document imaging. What we are wanting to do is print a barcode label to attach to documents so that when they are scanned in a piece of software such as vfiler will be able to read the barcodes and know how to file them.The main focus is our ERP system which is web based (PHP). We are wanting to modify the code to allow the user to print the barcode label immediately once they enter an order or PO. I have access to the source code for the ERP web pages. I don't know of any way to make a web page print to a printer without displaying the printer select dialog. So, I decided that I wanted to try and create a VB application that would do the printing of the barcodes. This would allow me to bypass the the printer select dialog.
Now for the question. Is there any way to have a web page (PHP) running on the server call a VB app to perform a task? So, if I had a button on the webpage and the user clicked it, that button would somehow send the pertinent information (Order number) to the VB app and the VB app would print the barcode. The VB app will always be running on the machine. The label printers will be Zebra USB label printers on each person's machine.
