Help realise download file from Dropbox folder on Visual Basic 2015

I need help in realise downloading file from Dropbox folder on Visual Basic 2015. I found example code only on ASP.NET, but I can`t translate it to Visual Basic code.

async Task Download(DropboxClient dbx, string folder, string file)
{
using (var response = await dbx.Files.DownloadAsync(folder + "/" + file))
{
Console.WriteLine(await response.GetContentAsStringAsync());
}
}

I have Dropbox account and local dropbox client.
I need read (only) file from my folder.
How can I get path to file ? How to save local copy if I need. 
Best regards, Alex.

The DownloadAsync method can be used to download files, as you mentioned, but to find the paths of files, you can use ListFolderAsync. That will give you a ListFolderResult, which contains entries with paths.

What have you tried so far, and what are you stuck on? Can you share any code and output that's giving you trouble?

Unfortunately, I have not yet ready code, even not working code. I ask step by step example on Visual Basic. Purpose: read file(mytxtfile.txt) from person dropbox folder. That`s all.

1. Definition of variables of Dropbox.Api Dropbox.Api. Which one minimum instances of variables do I need for my purpose ?

Dim dbx as Dropbox.Api.DropboxClient

What else ?

2. Which method do I need to use to get local copy of file from dropbox folder ?

Dim dbxFolder As dbx.Files.ListFolderResult

How to use dbxFolder to get exact file(mytxtfile.txt) ?

In general I need simple sample of code on Visual Basic how to get file. Thats all.

Thanks in advance.

In that case, I recommend starting with the tutorial, which covers the basics, here:

Since more than 6 months iam trying to figure it out, but it looks impossible to me, Finally iam here now

I wanna ask, i have uploaded a text file to dropbox, and i can see its content in my forms in VB.Net here is the code i used

Dim myWebClient As New System.Net.WebClient
Dim file As New System.IO.StreamReader(myWebClient.OpenRead("https://www.dropbox.com/s/yfarlrua18vbajo/PRUEBA.txt?dl=1"))
RichTextBox1.Text = file.ReadToEnd()
file.Close()

Now my Question is how can i edit this text or add more text into my text file from my VB application ? Is there any other way to edit this text from Visual basic only without using dropbox API ?

Faris, if you just have the shared link to the file, you can't edit the file.

If you have any further questions, please open your own thread instead of replying on this unrelated thread, so that we don't spam anyone else on it.
