Have An App Interact With Another Running Application?
Aug 3, 2011
At user login, launch an app I have created. This app opens a web site in a webbrowser control, logs the user in to the web site, and parses links from the resulting web page. These links are links to launch citrix sessions on another farm.
Create another app that appears on the start menu for the logged in user. User clicks on this app, it communicates with the launch app to basically click the href associated with the citrix app within the webbrowser control. Then this app will go away...
I have already coded the first app and figured out how to click links within the webbrowser control. What I can't figure out is how to go about implementing the second app, that runs as a separate app, but communicates with the first app to do its business. I see a plethora of options such as MFC, AppDomains, RPC, and so on. My question is which is the best practice to have one app interact with another and have the other app take actions based on that interaction? I prefer to stick completely to vb.net.
A good example of how I would like this to work - a web browser (IE, FF, whatever) is open on the desktop, user clicks a link in an email, link opens in running browser. An action in the mail client causes action in the browser.

When it comes to threading. I've managed to adapt one of JMcIllhinney's backgroundworker codebank examples to somewhat suit my needs, but not completely. I have a main form, and a second form that appears while I'm running through a for loop. It informs the user what is currently happening. I set up a backgroundworker that allowed me to continue to use the main form during the for loop, but the other "status" form was completely frozen, and any labels or graphics were shown as white boxes. I am struggling to figure out how to be able to move/interact with both forms while the loop is running.

I'm using SHDocVw.InternetExplorerClass to scrape a webpage. It works fine in XP, but when I try to run it in windows 7 I get an error:The interface is unknown. (Exception from HRESULT: 0x800706B5)
When I run visual studio in administrator mode it works fine, but the published application has to be run in administrator mode too, which isn't acceptable.
Is there any way to get around running the application in administrator mode?

I've search numerous hours, but I haven't been able to find the appropriate solution. What I want to do: Get the html of a certain webpage (Lets say in this case url...this html within my wpf application, so that you can see the content of the page you requested. Then I want to be able to trigger events on the html that has been loaded from the URL. Like I want you to be able to click on a certain node in the HTML and I want to be able to link this node to a certain value. Basically a crawler application that let's you request a page, see the page in a control and allows you to click in the loaded HTML and link values to predefined values you set. So basically I want to be able to get a webpage displayed within my application and be able to trigger events on the html (For example a click on the html which would need me to know on what node you clicked in the html, or for example be able to edit the html by clicking in it).

Which is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.

Let's say 10 desktop shortcuts, all with different names/icons, point to and can start the same exe application from the same directory. Is there any means for the application to know the distinct name of the shortcut that was doubled_clicked. Also is there any means for a running application to know if it was started by command line, by a double_click on the exe, by a double_click on a shortcut that points to it, or by another process' call?

I have an application that provides core services for a series of other applications.When another of these applications is started, I want to check that the service application is running and if not shutdown.What is the best method to check for the existence of the other app? I'm thinking that I should be using a global mutex in the services app and checking for it's existence in the other apps. Is this the correct way to proceed?

So I'm writing this VB.NET application, and it's doing things. But whenever I press a button to start some process, it does what it does except I can't click the window until it's finished. Otherwise the whole thing freezes. This essentially stops me from doing more than 1 thing at a time, because if I click another button (or anywhere) when something's running, it just freezes my program.

I am writing a program that is connected to an rs232 port and I need it to constantly be monitoring the incoming data. I think there are a few ways of doing this like checking the buffer but I need this to be running while I am connected to the port. I have a play button and a pause button for the port. When the play button is pressed, the port is open and the button is no longer enabled until the pause button is pressed. I need to have a while loop running the entire time the play button is no enabled, or pressed. I am having a hard time knowing where to implement it in the code.
