Logging into eBay Using VB Web Browser - vb.net

I have been trying to login to eBay through the web browser module in vb but I am struggling to find a way to fill in the boxes by using the click of a button. I have tried this by using the GetElementById as follows:
If InStr(TextBox1.Text, "EQP") Then
WebBrowser1.Document.GetElementById("1560960309").InnerText = "username" ' Username
WebBrowser1.Document.GetElementById("1605523682").InnerText = "password" ' Password
WebBrowser1.Document.GetElementById("sgnBt").InvokeMember("click") ' Click Login Button
This code doesn't do anything at all but has worked using other websites, before the eBay ID's used to be simple and I am now finding that these IDs seems to change in each session.
Any help would be great.
Thanks! :)

I believe you cant do this like you can on other websites as Ebay is trying to put a block on all ways of phishing. However Ebay does have an API for .NET that you should be able to use and in the long run it will look and feel much better. Here is the link : https://go.developer.ebay.com/netsdk
Hopefully this leads you in the right direction.
Good Luck!

Laravel tests from the website

I am looking for a way to make test cases that can be added to the admin dashboard of a laravel website. For example if a page on the website does contain a form to submit to the database in the dashboard the form can be tested for errors and even submission speed and if the form is collecting the right type of data integer field and string fields.
I click of a button and the forms and content will be tested.
I would really like to know how I can setup something like this but not really sure what to search for, any links are welcome to a website or message.
Best regards

Auto login to website using script or bookmark

I've been trying to figure this out using various different methods. I'm trying to create a script/bookmark or some type of quick action to open a browser tab or window with a specific URL, and automatically log me in using my credentials. I'm not all that concerned about security for this at the moment.
At first I figured I'd try to use a javascript bookmark to do this, but nothing I found in my research worked. Next I tried to create a bash script, but I couldn't figure out how to send the credentials in via the terminal. Most recently, I literally copied the source code of a site, created a local file and tried to hack together something where I could prefill the form data with credentials and use JS to submit the form, and I've gotten close with this, but for some reason when I use the JS submit function, it errors out and says that the username and password are invalid. But when i turn off the submit function and manually click "log in" on my local html page, it works as expected. I want this to be a one click process, so the idea of using onload/submit or something to that affect is really important to me.
The site I'm testing with has a Rails backend and my next attempt might be trying to use POST to do what I'm thinking, but that's currently outside of my level of knowledge on the subject.
Anyone answering: i do not want to use a password manager to accomplish this.
My requirement is that i will either be able to a) run a script or b) use a 1-click option to do this per website. Ideally i'd be able to set this up in a sort of programmatic way to do this with multiple sites, but I'd be happy with 1 at the moment.
i know similar questions have been answered before, but I haven't been able to use information from those posts (the ones I've seen anyway) to figure out a good way to do this.
Create a bookmark for the current page you have opened.
Edit the bookmark
Change the value for the URL to something like this.
(javascript:(function(){CODE_GOES_HERE_FROM_BELLOW})();
find the field for username and password on the page.
Given example for hotmail
var inputs = document.getElementsByTagName('input'); for(var i=0;i<inputs.length;i++){if(inputs[i].name === 'passwd'){inputs[i].value = 'YOUR_PASSWORD'}else if(inputs[i].name === 'loginfmt'){inputs[i].value = 'YOUR_USERNAME'}}; document.getElementById(document.getElementsByTagName('form')[0].id).submit();
OR
try out casperjs.
The proposed solution didn't work for me and rather than spending tons of time installing a testing framework that I'll never use other than for this purpose, I decided to try to do this another way.
First, I found out that the reason my JS wasn't working before is because the site did not allow a JS submit to be done, or atleast that's what it seemed to be when I got this error: "Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience"
The javascript I was using was in fact working, just not submitting. I used the following code to fill the fields (using "Class Name" elements on the page since there was no name or ID):
document.getElementsByClassName('username')[0].setAttribute('value', 'user');
document.getElementsByClassName('password')[0].setAttribute('value', 'password');
As I mentioned, the problem was when I tried to use JQuery to submit the form: document.getElementsByClassName('loginForm')[0].submit();
Which is when the above error cropped up. I can't really say for sure whether this is the root of the cause, but the page does submit, but I get an invalid username/password error when I do
I haven't figured out a great way to get around this just yet, but my short-term, "hacky" solution was to use Applescript to send a return keystroke to the browser to submit the form. I'd ideally like to figure out how to get the submission to work using JQuery, but I'm not sure how to get around it.

Showing file selection UI : Integrating Dropbox with OAuth 2

I am trying to create a web page which will allow my user to upload a file to my S3 storage. For choosing the file user can use Google Drive, Dropbox and also local system. Am facing issues while implementing the Dropbox part of this.
Am using this technique for integration(using core API and OAuth 2).
First when user chooses Dropbox i am opening an HTML page in an IFrame. Here I have an authorize button which will open the authorize endpoint mentioned in the above link. This link shows me X-FRAME-Options error inside the Iframe so i had to open this link as a popup to work.
Is there a way around this? I'd like the authorize URL to open in the same iframe by using location.href.
Also when i open it as a popup, after the user logs in successfully the redirect_uri which i pass i getting opened in the popup. I had to do some unconventional setInterval coding to go around this. Can someone suggest a solution for this as well?
I also tried using CSRF tokens as mentioned in Smarx's blog but this also gives me the same error.
EDIT :
#smarx i tried using dropbox.js and it works fine. Stuck at one place
I used the OAuth popup driver and have a button which says sign-in.
First on load i create the client and then the popup driver as below
client = new Dropbox.Client({ key: client_id });
client.authDriver(new Dropbox.AuthDriver.Popup({
receiverUrl: "http://localhost/uploadCare/dbcallback.html"
});
);
And in the call back html i am writing
Dropbox.AuthDriver.Popup.oauthReceiver()
as mentioned in the docs.
But this does not take me back to the original page and show me the list of files.
I particularly did not understand this part of the explanation
"To use the popup driver, create a page on your site that contains the receiver code, change the code to reflect the location of dropbox.js on your site, and point the Dropbox.AuthDriver.Popup constructor to it."
Could you please help me out here.
You definitely can't put dropbox.com into an iframe, for security reasons (e.g. clickjacking).
A few suggestions:
Can you just use the Chooser for your use case? That would certainly be easier for you and your users.
If you can't use the Chooser, is there a reason you're not using dropbox.js? It has a popup auth driver that will pretty much just take care of all this for you. The redirect will definitely happen in the same window as auth, so communication between the windows (usually via localStorage) is generally necessary. This is already done in dropbox.js.

Login to Google from iFrame

I have seen that it is not possible to display any Google page from an iframe. An error message is displayed: cannot display, open in a new window.
I need to login to Google (OpenId authentication) from an iFrame in Joomla (cannot change this). Is there a workaround for this? I thought I could open the authentication page in a new window, and then try to kill that window and reload the original one, but I am not sure I can do that.
Thanks
Well you can just get the form (html code) and put it in your iframe but this will get very messy, for example, there maybe certain JS files that you need to include as well.
Redirecting to Google is best way to implement it.As Using IFrame Sometime does not allowed by some Companies Due to Security.

POST a HTML Form programmatically?

I need to POST a HTML form to a 3rd party website (a Mass-SMS texting system).
In the past I've done this by forwarding to a page containing a form I've pre-populated and hidden (using display:none), then I've ran a javascript function at the end of the page to automatically submit this form.
However I'm hoping theres someway I can do all this programmatically (as I don't care about the response, and the user doesn't need to see the page the form is being posted to).
How can I do this? Cheers
You could use a WebClient.UploadValues method to send an HTTP POST request to a remote server from your code behind. Just fill up the name/value collection with the values coming from the hidden fields.
If you're willing to get into PHP, you can very easily use cURL for this.
Otherwise it's going to be quite difficult using just Javascript.
