what are the codes in Visual Basic 2008 to auto post to forums using either the webbrowser control or HTTPWebRequest method. The forum that I'm trying to automate is www.blackhatworld.com (just an example site). basically, show me how to automate the login and post a new thread with only a click of a button.

View 1 RepliesI need some advise as to which options I have to go about this problem.I want to to create a simple application consisting of two text boxes.One for username Second for Password And then a submit button.What I want is when I enter user/pass and press submit.It should only give me a single message "Login Succeeded" or "Login Failed". The forum I trying to login into is : warez-bb.org What are my options to go about this?? I have considered Sockets but thats in VB6.Still,I couldnt get it to work.It doesnt even connect warez-bb on port 80.
View 2 RepliesI'm trying to make a program that will automatically log me into a forum. I have the webbrowser control and a button. the site is automatically loaded on form load. I want it to log me in using my username and password when i click the button. I tried it on [URL] to test and worked fine. But for some reason when I try it with my forum it doesn't work. My forum is SMF. It seems that the problem lies with the Login button itself.
I can easily send the username and password to the corresponding boxes but when it comes to clicking the Login button it fails. What makes that Login button different from the Login button of Yahoo other than having a different name? Below is an example of the code I was using. How can I get it to successfully click the SMF Login button?

View 1 RepliesI am trying to automate login and navigation to a website using the WebBrowser control. I can successfully logon to the site using the wb control but after that I can't seem to get access to the newly loaded document's elements within the same routine. I check for ReadyState Complete and IsBusy but they don't seem to be working. There don't appear to be any frames being used at all so I can't figure out why this won't work. I know that the wb control is successfully logging in because I can see the page load in the wb control. However, after the page loads I try to access the HTMLDocument for the new page (after logging in) and it is either set to Nothing or it's the previous page's HTML. I've tried putting in a Sleep to wait for the page to finish before trying to access the HTMLDocument on the new page but it still doesn't work. If I create a button on my form that accesses the HTMLDocument and click it it works fine. I can't figure out how to ensure that the entire page has finished loading within my routine. I tried putting a switch into the DocumentCompleted event but that doesn't work either.
View 2 RepliesOk, so today I wasted a bit of time looking for ways to use a text file to save login information. Basically, there are two fields, username and password, and two buttons, sign up and log in. When you click the log in button, I want it to verify the information entered in the fields, and when you click sign up, I want it to add the information to the file. It doesn't seem that difficult, but I'm have a lot of trouble finding a way to do it. I would be very grateful if I could find assistance with this on these forums.
P.S. If it was my decision it would obviously be using a database, but for this particular program I need to be using text files.
How do I automate a web page (e.g. retrieve page text, login website, search, click button or hyperlink) via WebBrowser?

Welcome to the All-In-One Code Framework! If you have any feedback, please tell us.
it might help to change the forum name to Visual Basic .NET General Forum. or VB.NET General Forum maybe would help the vba and vb6 developers know this is not for them.

I am new to vb 2008, but I know how to automate some html elements. The issuse that I running into is that I cannot get my webbrowser1 to auto-click the "Gmail" button at the top left of the page or the "Show me my account" button on the righthand side of the webpage. Here is the webpage that I'm trying to auto click: url...Can someone please view the html source and give a code sample to click either button so that the page can then go on to the following page?

Changed thread type to QUESTION. I was then able to mark AS ANSWER the relevent post which now also immediately follows this post and so it is easier to find as suggested by forum user j2associates .
<edit> It is also my 3rd post in this thread, the 8th one up, of my posts, from the bottom ( for now ), as the forum format has changed yet again.I will leave the rest of this post( as is ) purely for historical reasons. I have been on these forums long enough to see 3 forum changes. <edit> 19th May, 2010> Link added to a video on the next line of text.

I want to create an application similar to "Windows Live Writer"(that is for blogs) but this one is for forums..This application is solely for my personal use only.I would like to have a facility where I have 2 text boxes--> One for username and one for Password along with a submit button.On clicking Submit I need a msgbox to display whether Login Succeeded or Failed, and depending he should be directed to create a new post in any particular section of that forum..Consider for now,the forum I am trying to do this is, vbforums.com..Its just like OFFLINE creating and then posting..I have already created forms,BBCode Editor, GUI for this purpose and want to start with Communication coding.I tried using Http request but based on its response I dont know how to distinguish between valid user and invalid user.

View 6 RepliesI looked all over the forum posts here and didn't see the answer to a question concerning iframes within the webbrowser control (there were similar issues however). The forum has a classifieds section that allows members to post threads daily. I have a message that I like to send once every day to a forum and decided that it would be best to achieve this programmatically. However, I noticed in the visual basic 2008 webbrowser control, that it doesn't seem to automate the iFrames within the browser using the htmlelementcollection codes.

View 2 RepliesWe are currently changing our Antivirus program which involves uninstalling our current one first. That isn't a problem but we have several laptop users not in the building who might have a problem uninstalling programs.
It should be possible to write a script/program to automate the uninstall process I guess, but don't know where to start. Can someone point me in the right direction?

as for the exception concerning threads being aborted from other threads being dangerous, how is it possible to send a message from a main thread to another thread to abort itself? as far as i know the only way to a abort one thread from another is to just kill it (because i dont know of ways for a thread to communicate with another).

I'm firing a thread to unzip a file. I need some way of indicating to the parent that the unzip thread has ended. I've tried raise event in the unzip thread to a sub in the parent but this runs the sub from the unzip thread. With ApartmentState set to STA, so that I could use a save dialog, this was OK until I displayed a messagebox which was hidden behind the main UI(and whatever I did I could not get it to the front).

The problem is, I have an error in the red lines.The error is: INVALIDOPERATIONEXCEPTION "Cross-Thread operation not valid: Control tbPlaca1 Accessed from a thread other than the thread it was created on."I don't use cross threading. Each TB only was accessed for the correspondent thread, and for the "main program".
This is the error message I am getting:
"Cross-thread operation not valid: Control 'Panel1' accessed from a thread other than the thread it was created on." The reason I am getting this error is because I am opening up a new form and then calling these three things:
Panel1.Show()
Label1.Show()
Label2.Show()
why I get this error message because it doesn't occur normally if I open Form2 after closing Form1, it only occurs when I open Form2 after closing Form4.

Would anyone be able to help me here please. I'm fairly new to VB.net and threading so im just trying to figure out what is happening.When I debug this I am getting the error thread operation not valid: Control 'ProgressBar1' accessed from a thread other than the thread it was created on.
I'm a little lost as to why the error is occuring or how to fix it. I've had to put the progress bar in a separate thread otherwise the GUI crashes
