Why would you want to do this? Sounds like spam to me.

[aymenbnr]

it is for testing purpose only !

anyone can help fix this code ! i'm just getting started with coding i just want to know where was my mistake !

Thanks to all !

It is in your Do/Until loop on line 30.

Your WebBrowser does not have time to load a page, set values, and move on to the next link. The Do/Until loop probably goes through all the urls from your file before the first url even has time to load.

I would load your file into an ArrayList, send the first item(url path from file) to the WebBrowser, let it load, set values, and THEN move on to the next item in the ArrayList until the last item has been loaded.

Btw, it does seem like a spam bot, just posting multi-posts on different sites without being able to know what the content on each site already is. It could possibly be a Holidays Greetings bot, to send "Merry Christmas from..." to all of your friends. Or just simply for testing, although I do doubt as much.

thanks for your reply codeorder ,but how to make the browser wait till the url loads then move to the next line ?

Use the _DocumentCompleted event for your WebBrowser, to give it time to load the page and set values, then at the end of that Sub/Event, move on to the next item/url in your list.

In a recent project, I previously had to check if a value was set in a WebBrowser's TextBox/Textarea, before moving on to loading the next page.

thats what i thought too !in the code above you will see that i use document completed event to do that ! and it didn't work !

In the _DocumentCompleted , after you set the values to a page, THEN... IN THAT SAME EVENT, load the next page as the last line of code until the last url has been used.
