Hi
I would like to create a script which loads a program on my windows based computer, clicks on one of its buttons, and checks the data inside it (it gets its data from the web). Should I do that in C#? Any example out there?
The program contacts the web and displays information. I would like to get notified when that data has changed.
UPDATE: I've learned that the application doesn't contact a web-service using Charles. This means I have to load the windows application, click the button and look there. How can I do such a thing? I know it is disruptive, and still I would like to do that.
You need to download Wireshark to see what http(s) the program is using.
And once you come to know about http(s) used, you can use the WebRequest and WebResponse classes for making request to the server.
The method you described in checking for changes is quite disruptive: the script you intend to write needs to load the program and clicks the button. The loading and clicking is enough to disrupt whatever you are doing when the script runs.
I suggest changing the method to access the web directly to check for changes, and only displays a notification (WPF or whatever method you are comfortable with) when the data changes.

I have explained my project below and asked some questions with "My Question-" tag.
I have working on a project. At the time of windows logon page if I enter a wrong password my cam should take the picture, If I open regedit my system should take a screen shot and save these images in C:\Windows\system32\new folder (I tried a lot making this work with the help of manifest files but failed everytime) and emails it whenever finds an internet connection
I have a form based app because I didn't find any other way to capture image from webcam directly but taking input from pictureBox1.Image.
My cam, screenshot,email (didn't find a way to autocheck if has internet connection available or not) and 3 events checker for "firewall enable/disable, windows logon failure , regedit event called" are done and they are working good.
What I need to do is to assemble these codes to work as an app and running in the background continuously from the time of windows startup to shutdown
To validate positive events I need to make a desktop based db ("My Question"- still figuring out either to choose sql or localdatabase in c#. Please also tell me a suitable solution.I have to delete all the entries from the db once a day is over). The db would contain the following columns (event id, event name, event timestamp).
I want my app to check if this very event exists in the db then it should ignore the event generated on windows event log else it should make a new row with the db columns and it should do the following actions based on the event like taking webcam pic or screenshot.
"My Question"- I want my app to be live at the time of windows logon page. A lot of programs start later when you are authenticated but I need my program to be live at the time of logon page. Do I have to make 1 or many services? or multi-threaded? because in the typical form based app you can only call one function at a time and wait for it to return something or perform some task/action and then you call the second third whatever.
"My Question"- Do I need to use the backgroundworker in c#
Please help!
You have a lot of things going on here for one question.
You can put all your code in a background service that gets started at boot time. There is a walkthrough here to show you how to do that (along with a million other sites).
Addressing some of the other issues you listed:
Google is your friend...
Webcam - Found a quick reference here and here
File Modification - Another SO thread here
SQL vs. Other Database - Not sure you need anything elaborate here, probably something you can put together pretty quickly. Another SO thread addressing that here
Good Luck!
I have a WPF browser application that collects user data and adds it to a database to tell them when their software is out of date.
All of that works fine, but the problem is when the application finishes its stuff, I want the web page itself to change (i.e., detect the web app has hit a 'finished' state, then autonagivate to a results page or something).
I can't think of a way to accomplish this, since the web app itself doesn't seem to be able to change the IFRAME it's contained in, much less the page outside of that, or signal to javascript or anything.
Any ideas?
I'd make an variable to keep progress/step of work. And a timer which would check if progress=="done" or sth.
Maybe this is not the best way of solving this but I don't know WPF much and that solution first came to mind
My basic issue is this, I have events firing on pages I've left based on network activity that are causing problems when I thought the old forms were being destroyed.
More detailed information: I am writing a windows phone app that communicates with a network player. I have a static instance of my communication class in my App class so all the forms can share the connection, and all my forms subscribe to it and process results within that form. From a main menu you can choose one type of source and it opens a file browsing form that refreshes a listbox as you navigate, cancels the back button and refreshes the new contents to simulate file navigation until you are the root folder. The app doesn't know if you're clicking on a file or folder, it gets a network message when media starts playing and watch for that and then navigate to a "play" form. I had been using all .Navigate's for this until now and it worked great until I added another branch off the main menu for a new source. Although the new source is completely different, the device sends a lot of the same generic commands which just mean something else in the current context. After visiting the my file browser form and going to my new source, a play command from the network, which means something else now, would cause my to jump into my old "play" form from the previous source as if I was still on the file browser form, which isn't intended.
So I've tried many things and have it kind of working now but it's message and I lose some features. Currently I changed from using all .navigates, also in the back button override, to trying to use the stack and navigate.goback's. I pass variables when needed using globals in App and unhook my net listeners from the form, goback, and then connect them in the new form's listeners in it' navigatedto. I think there is timing issue though as in some cases I needed to send a command to the media box as it's changing and it ended up triggering the wrong event handler again. I think the easiest solution, if possible, and they way I though it would work is if each time I navigated from the form it old one, it's handlers, etc were all destroyed and I didn't have to use the stack at all, handling all the back buttons myself.
I know that's a long description and thanks if you made it this far, hopefully it made some kind of sense. Does anyone have any suggestions on what I can do?
As a side note I'm a long time self-taught VB programmer who has been stuck in .net 2.0/winforms and I've just now made the move to C#, OOPs, and XAML to write my first Windows Phone app so it's likely I'm doing something stupid or overlooking something obvious...
It is likely because something has retained reference to the form. The most common cause is event handlers.
So, if your static class exposes an event, and you subscribe to that event in a form, you must unsubscribe from the event when your form closes / navigates, otherwise the form will remain in memory....
If that isn't the case, look for something else that is acquiring a reference to your form and not releasing it.
Most likely the problem is based on a bad application architecture, when it comes to handling commands send from the UI.
When you say 'sends a lot of the same generic commands which just mean something else in the current context.' you most likely reveal the source of the problem.
As a workaround, you can define an interface, that your communication class implements. Each form has it's own method it calls on a communication class instance.
If you indeed receive a command from a phone page, that is no longer in view, just don't process it.
You can store the navigation history to always know what page is the only one allowed to send commands to a communication class.
There's a certain website I need to access multiple times each day that requires me to enter my login name/password first, every time. To save some time, I copied-and-pasted the HTML source code and pre-populated the text fields with my info, then saved that to my desktop. Now I can just open that doc in my browser and click "submit" without having to type anything.
I'm wondering if I can go a step further. Whatever data is sent when I click "submit" — I'd like to start with that step.
From what I understand, the form info is converted into a POST request and sent to the web server. Is there some way I can concoct that request manually (without using their login screen) and then execute that request each time I need to access the site?
Thanks!
wow, what a safe site! Anyhow yes you could do this lots of ways. Not a good idea to transmit tho locally. Have you ever just tried using one of the form auto forms plugins for FireFox? one button and it will populate your form for you.

I assume you want to do this in an active browser because you want to be able to interact with the site after logging in, correct?
A really simple way to do this and end up with a workable browser might be to try using WatiN. The library itself is generally used to automated in-browser testing. But at the hear of it, that's kind of what you're doing here. You just want an executable that will open a browser, navigate to a page, populate a form, submit, and present the result.
This isn't so much from the perspective of crafting the POST request manually, but rather just automating the UI interaction.
Ultimately, though, it's going to be a matter of testing it for what your user experience is like. Does it take longer than you want? Does it leave the application running in the background unnecessarily? etc.
Honestly, this might really be overkill. Browsers have form auto-population these days. Maybe a browser plugin to take advantage of that instead? How transparent does it need to be?
Hey guys, here's a unique problem I have to solve: I have a program which opens up a webpage through a WebBrowser object in c#, and does a bunch of operations with it. Now I need to integrate this functionality into my own webpage.
That means that either I need to take the c# code, and somehow make it work in my webpage itself (put in a WebBrowser object, set up event handlers, etc), or I need to somehow have my webpage open this program on my server, fire an event to start, and receive input from it. It is very important for me to use a WebBrowser object (or even WebKit.Net) because there is a lot of javascript, etc on the page that needs to be processed.
Any ideas on how to pull this off?
I expect that you'll have a problem running a Windows Forms control inside a process that has no Windows message pump. I don't think this will work directly within an ASP.NET site.
On the other hand, you can place the control and the code to manipulate it into a Windows Forms application, which can then host a WCF service. The ASP.NET application can request that the Windows Forms application do the manipulation of the control on its behalf.
Of course, you'll need to handle concurrency and state issues. If there are two requests from two different users at the same time, then you'll probably want separate instances of the WebBrowser control to handle them. If request 2 depends on what happened during request 1, then you've got state issues, and you'll need request 2 to use the same WebBrowser instance that was used for request 1.
This does not sound like fun. Instead, it sounds like an attempt to use a desktop design in a web application - that typically fails.
