VS 2008 Develop A Web App That Can Interact With Websites And Carry Out Automatic Tasks?
Sep 7, 2009
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?

Ineed a VBS script that removes all scheduled tasks which start with a specific string.
For example, delete all scheduled tasks which start with "My Application Tasks..."
I wanna use this VBS script in my application uninstaller so all tasks created by my application are removed at the uninstall time, however am not familiar with VBS.

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 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'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.

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 an application that I need to automate where at a certain time each day, say 6pm, it will run a certain method(which is to check a database for key terms and then access the api to search for these terms). But there is also another process which is running all the time accessing the stream api so when the search is complete, it interrupts the stream and hands over the new terms.
Now I thought of adding the .exe file to windows task scheduler but not sure if that would work. The stream method run indefinitely and at 6pm each day another process needs to run. I thought of using the system.threading.task TaskFactory but when I include it, it shows taskfactory as undefined. ( I do have .net framework 4.0)If it launches using the task scheduler as 6pm with my code logic as follows:

I need to create a custom panel that will let me add items to the 'Panel Tasks' list: how I might accomplish adding items to this list and make it usable during runtime? I look at the Controls.Panel properties, but nothing was immediately apparent and, surprisingly, I wasn't able to find much via Google.

I'm currently using a webbrowser control to extract information from multiple websites. At any given time, my application could be searching through 1-80 different webpages across 1-4 different websites. On my computer, it runs pretty quick. I could go through all 80 sites in just a few minutes. But when on another machine with fewer resouces, it runs awfully slow. Taking up to 15 minutes. Which kind of beats the purpose, but not entirely, of my application.
I'll begin by explaining my methods, and go from there. When utilizing the Webbrowser control, I use While statements and Application.DoEvents, instead of the Webbrowser controls's DocumentCompleted event. I'm wondering if this is one thing that could be slowing down the process. Though I'm not sure why it would be. Also, would utilizing separate threads help with this? I can't imagine it would boost performance. But I'm not entirely sure. I think it bogs down because the application uses so much memory when running. On idle, the application uses about 9.5k memory. When running, I've seen it go as high as 110k.

I read some posts in the vb.net forum for how to modify your host file on your computer adding the domain website to block. this worked great. Then i went to a website such as vtunnel.com and was able to view the blocked website through it. So to still block it I need to add [url]... to the host site as well as any others?

I have the following code which sets internet explorers proxy settings to what ever i want and if i set it to use a proxy ip and port i get a 'Page can not be displayed' error. If i reset it back to the bloxx server again which is: http://gc-bloxx:8080 Then it works fine. What i am asking is, can i get the app to connect through 'http://gc-bloxx:8080' and then set the proxy ip and port so the app can connect to the internet and then unblock the websites?

I'm trying to get my program to go to the memberlist.php of a phpBB2 forum and gather all the links to the members websites.
Example: [URL]
I want the program to go to that website and save all of the websites (the ones that have the "www" image) to a list inside the program. I have no idea how to do this, but that's not all, considering most forums have several pages of members (this one has 32 at the moment) it has to go through all of the pages and gather all the links from every page..

Stuck on resolving host IPs within a listbox. I want it to carry over the resolved IP's to listbox2. But also have an 2 radio options either to resolve IP to Hostname or resolve Hostname to IP. Thus when I hit the start button, it checks to see which one is selected and starts the process. Here is what I have found, but can there be a simplified version to this but for lists? [URL]..

I only need the info from one column in order to generate the entire record, but how do I carry the info retrieved from the search what the user selects into the new form in order to populate the new form.

I am trying to rotate a select number of bits to right with click of a button. ( bit 7 to bit 0 and rotate.) The patterns should not matter. It could be any combination of set or reset bits. The bit patterns are selected by checkbox0 to checkbox7. I like to rotate without a carry bit. Is there any way(s) to do this?

I�m using the my.computer.network.downloadfile (something like that) to download the html source to a text file. It has been working for about a year now.
Today it stopped working and the downloaded files are empty. I�ve talked to the people at the website, and they say they haven�t done anything. But they always say that.
Is there a way to "block" an automated download process of this kind, and how do I get around it?
