Make A Program That Will Log Into Various Websites In Firefox?

May 5, 2012

I need to make a program that will log into various websites in firefox. I have done this using the webbrowser control. But now I need to do it using Firefox. I have looked into HTTPWebRequests but with that it seems that you are just pretending to be a web browser. I actually need the page to load and log in in firefox. Considered just bundling a load of sendkeys in but that is very un-professional.

Jan 17, 2012

While running an application in the IDE, the program properly handles Try/Catch/End Try blocks. This works fine for the most part, but is it possible to have errors generated in these blocks stop execution at the line with an error on encountering an error?

Create A Program For Parental Control That Block Specific Websites?

Jun 12, 2011

I have used VB6 years ago. Few days ago I just got started again with VB 2010. So I'm newbie again, Almost forgot everything. I want to create a program for parental control that block specific websites.

What I exactly want to do is The code should check the titles of the open windows and see if it is blocked one. If it is, it will close the browser with a message showing it's blocked. For example If I put "yahoo" to check and someone opens yahoo.com it should be terminated.What I have done so far is, I made DOS batch file that will terminate all the browsers that are open and set that ready to run when the title matches blocked site name/address.But I am stuck at how I can check the titles of the window that are open.

Create A Program That Connects To Several Websites, Logins, Then Post Some Data?

Nov 29, 2009

I use Visual Basic.net to create a program that connects to several websites, logins, then post some data. I can't use the httpwebrequest, some java is required on those sites, so i use the webbrowser control.Now I created a form, some fields for input data and a submit button. The coding part is like this:

Code:
sub website1(vars)
'login here
'post some data

[code].....

The problem is that I can't control what happens after submit button is clicked. I need to pause or stop the process at any time. If I exit the program while processing, I can see that even if the window disappear, the program is still running!I tried to use a thread for this, but the subs only get called if I use begininvoke, or invoke on a starter thread.

How To Do Nested Case Blocks

Feb 29, 2012

I am working on a project that requires that I use nested case blocks. However, I am not quite sure what this looks like. And for whatever reason I'm having a hell of a time trying to find the answer through google. Are nested case blocks like nested if blocks? Or are they something completely different? More information on the project can be given if needed.

Block Like ShowDialog Blocks But Without A Form?

Sep 10, 2010

So you know how when you call "Form.ShowDialog" from where ever you call it, it blocks until the form being displayed closes. And then the function returns whatever result it was.I want to know how to block like, but without a form, yet still have the "main ui thread".Basically I have this long process that needs to thread out and do several things... and it's heavily event based. It jumps between two threads, the main ui thread, and it's own background thread. The main ui thread needs to have access so that I can randomly open different dialog boxes for things... sometimes they're just windows asking to hit OK or Cancel to continue, others it's to perform some action, etc etc.

But there is NO central form related to it. It's a complete background thread running that randomly hops over to the main ui thread for things.Right now I have this class I designed called lets say "DoJobProcessor". On it is a function called "BeginDoJob" that threads off from the thread pool... when ever I need to jump back I use a ManualResetEvent to block on the background thread, jump over to to the main thread with "invoke" and passing a reference to the MRE, then release the block when done there and continue on on this background thread.

All while this is going on I just set the form I'm trying to block the main ui thread from managing by just setting its Enabled property false.It all feels just messy and annoying... and I was just writing something using ShowDialog and I was like... HEY, what if I could block this BeginDoJob method, hi-jack the main ui thread, then let that function return the result when done instead of having this "Complete" event with the return value in it. It's obviously possible because ShowDialog does it, but I don't know how.

This way the job I'm performing isn't always waiting for the main ui thread, instead its the other way around... the ui thread waiting for it, the way it aught to be. Show something, branch off do some stuff and just idle the display while it does it, come back show something else, branch off and just idle while it does that.

Handling Errors In Try/catch Blocks?

Jun 11, 2011

What is the convention in VB when a sub requires that a try/catch block succeed in order to function, but the catch block doesn't bubble the exception up?

I could put all of the code into the try block, but this seems messy since most of it doesn't need to be tried, it just needs the try to have succeeded.

For example, should the catch block exit the sub? This would work in my current situation, and if it is the proper procedure, let me know, but what about the more general scenario where both both success and failure require additional processing?

.net - Calling New StackTrace Blocks When Closing Application

Sep 12, 2011

I just did some analysis by using a global function which is called GetCallingMethod in my case.

Mostly it works great. But some cases the application is blocked. It is blocked when closing the application. When going to "pause" in Visual Studio, it stays on the new StackTrace line forever.

In my application I am using third party references, multithreading and several classes. But all that should not be a problem and should not lock the tracer class as far as I imagine. I am using Visual Studio 2010 Ultimate in this case.

This line will never be left in development area. Application will is frozen. Try/Catch will not force the procedure.

Socket Programming - Read Blocks Indefinitely

Feb 17, 2010

Following is the code that I'm using for reading data over a .NET socket. This piece of code is run by a single separate thread. It works OK the first time, on the second iteration it stops at "client.Receive(buffer)" and never recovers from it. Initially I was using recursion to read data but changed it to iteration thinking that recursion could be the source of problem. But apparently it is not.

Adding An Image To 1 Of The Tabs On A TabControl, Blocks My Tab's Text?

Dec 9, 2011

Using Visual Studio 2005 (vb.net) (windows forms) on Windows XP, I have a standard Microsoft TabControl.A button click adds/removes an image from 1 of the Tabs.Seems like the image is placed OVER my tab's text, making it unreadable.Why isn't it like it should be: Image on the left. Followed by text on the right.Why is the image being placed OVER my tab's text? Do I need to do some kind of "refresh" or "redraw" before it will appear as it should? I don't see any way to "make the image appear on the left edge of the tab". (NOT the tab-page.) ... and then place the text just to the right of the image. (Just like a normal image+text tab can do.)The code is pretty simple, it just gets an image from my ImageList: cfgTab.ImageKey = "PadLockClosed.png"' Show CLOSED PadLockThe tab's text changes from: This is my tab text to: T(IMAGE HERE)is my tab text The image appears OVER the beginning of my text. But if I move to another tab, then move back, the image appears in the correct position:(IMAGE HERE) This is my tab text
