VS 2008 Interact With A Service?
Jul 13, 2011
I have never interacted with Varbiles outside of the projject but now in need of it.I am developing a Windows Service Application that is multi-threaded. There is going to be a set of Global Varibles in the application that contain basic status information such as how many threads are currently running, What clients are currently connected etc.
Now I would like to develop another application as a monitor. This one would be a Windows Forms App and its sole purpose is to display to the user this information so that is can be monitored.Is there an easy way of doing this? If not I don't think I will bother as the Monitor is not essential.

I've seen loads of programs that use an icon in the system tray to let you interact with a windows service that is running on your machine but I am curious as to how this works. As I understand it, unless a service marks itself as 'interactive' then it has no way to communicate with the user's desktop and doing so is discouraged by MS (and even causes an alternate desktop to appear temporarily in Server 2008 in some cases). So I want to try and avoid doing this but I cant think how else I would do it, and even if I marked my service as interactive I'm not too sure how I could actually get it to show a notification icon in the system tray.
I assume I would have to use Windows APIs, unless just using the windows forms NotifyIcon class would work. I considered just having the system tray icon in a totally separate application that just communicates with the service via named pipes or TCP etc but I'm pretty sure this isnt how other programs do it because with most of them if you just kill the process that the service is running in then the icon disappears so it must actually be directly running from the service.

My application needs to be a service (it needs run regardless of whether a user is logged on), but I also need some sort of client control/oversight over what it is doing. What is the optimal way to do this?Write a separate application to communicate with the service application - I see that as best solution in terms of stability, since the applications will be decoupled somewhat Use callbacks on system events in the service application to load UI forms directly from the service application - I see this as being easier to deploy.

Is there any work around to this Error: [URl]..I have a Windows Service that needs to interact with the desktop (actually just the Systray). This service is working fine under WinXP, but not under Vista. After reading the article above I find it difficult to comprehend that Microsoft would simply just "do away" with support for "Interact with Desktop" because of a flaw in the OS (this is an OS problem, not a developer issue). I've never heard of any professional organization removing a feature because they can't figure out how to make the feature secure?? I'm hoping this article is just out dated or was not for the released version of Vista.Under Vista Business x64, the option to "Allow service to interact with desktop" is a check box in the Service Properties (Log On) tab, so if this feature isn't available for Vista, when is the option displayed?? But it does appear that the check box does nothing when checked.

I want to start building my first large program. I want to create scripts on their own and allow them to interact with my main sub. I guess if I need a "plane" in my application, that could become it's own class? If I wanted to calculate "purchases", "money" I could create a DLL? I don't want to have to change things and have to recompile my entire application every time I want to change how something works for example.

I'm using Visual Studio 2008 on an XP machine and am trying to develop a web app that can interact with websites and carry out automatic tasks.One problem I have is trying to recreate the web requests for automatic interaction.
For example:I use a webBrowser control to allow me to surf a page manually. Then, once I am at a specific location, I'd like the automatic interaction to take over.Part of the website requires a log-in and exchanges cookie data.When I try to read the cookie info from the webbrowser control to build the subsequent automatic requests, the cookie content is incomplete.Upon further investigation, it appears that the site sets one of the cookies to "http only". This stops the value being visible to the webbrowser control.Is there another control or method I could use to retrieve this info?

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 have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

Have a Windows app that needs to interact with a stand alone program that is accessed using cmd.exe. From Windows app, I can execute cmd.exe but cannot interact with it. Tried SendKeys, but this only sends one key at a time (sometimes more, but inconsistent) with multiple cmd.exe windows opening. Need to be able to send a whole command (string) to only one cmd.exe window.

I'm looking to pick up a programming language. I've viewed some source code of both VB and C# and VB looks like something that I can pick up well.My question is can VB handle creating apps that will interact with the web? Things like signing me into accounts, downloading information, things of this sort?

how to display and interact with a website, at the moment its just research on how to go about it. Once i start i may need some more assistance. But for now just research At the moment Ive came up with using WebClient and HttpWebRequest/HttpWebResponse to interact with website data. And i know VB.net has an inbuilt site viewer (just a wrapper for IE).The website im using is an Intranet page for doing VOIP calls. It uses a large collection of JS(jQuerry) mostly. I can probably get the dev to make a .php file to
<?php
print_r($_GET); Prints all GET variables in a quite readable manner.
print_r($_POST); Prints all POST variables in a quite readable manner.
?>
to find out what GET's and POST's there are, but I'm not sure if JS stuff gets put in as a GET or a POST as its in the DOM.So all in all,I'm wanting to make a "Desktop" variant of there client. So basicly just a viewer of the dial pad. And detection of new calls in the queue, things like that. So i want to read data from the website, display the dialpad(just showing a segment of the website) and send the request to accept a call(and maybe a few other small pieces of data).

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.

Im not understanding something or I am missing something.I can't use: "Imports Microsoft.Office.Interop" as it is not recognized.How do I interact with an Excel file? None of the examples I have viewed have been able to work.I opened one VBform (only the form) by ".paul." (in his sig) but could not get it to convert to 2010 and although I was able to get his code loaded I could not use any of it.The strange part is in his module there were no errors, import (copy and paste) any of it to my project and everything had errors.I believe .pauls.'s example was:"Imports excel=Microsoft. Office. Interop" which was not being accepted in my project.

I am trying to write a program that displays a medium opacity image as the topmost form. that I can handle, the part that is giving me trouble is that I want windows to "ignore" the topmost picture form and allow me to interact with any forms behind it (mine or otherwise) as if the see-through form isn't there. I have searched all over but cant seem to find a way to do this.

So I am currently using the method of combining a timer with a WebBrowser control to constantly check if some particular text has appeared in the WebBrowser control on my form. The text is dynamically generated after some arbitrary amount of time depending on the user's internet connection speed. (I'm using DOM to do this). The code to check for the HtmlElements lies within a function, which is turned called by the timer.
I find that this is kind of crappy and occasionally lags the UI interface, if not making the entire program behave sluggishly. I have been thinking of just using a simple while loop in a worker thread to take care of the issue, but I understand that new threads cannot interact with the UI thread directly (including controls); they have to call wrappers that are present within the UI thread.
So my question is, can you declare a WebBrowser control and still interact with its HTMLDocument properties if you declare it within a worker thread? I don't want the while loop to be executed within the UI thread (by using a wrapper), since that would defeat the purpose. I would also like to avoid DoEvents() as much as possible...unless that's the only way to do this thing?

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).
