It could also be that you need to copy the files themselves (images) from the source solution, and put them in the exact same folder (the resource manager holds a reference to the file added to the .resx).
I never finish anyth

That means the field is not a blob (thus, it can't be converted to a byte array). Please check the data type of your "pic"
Best,

I can't seem to find any way to get a GUI in Cosmos OS. I have went on Youtube, Stacks, and more. I did not find any methods that work. If anyone can please help me that would be awesome! Thanks in advanced!

What does this have to do with C#?
The difficult we do right away...
...the impossible takes slightly longer.

Believe it or not, Cosmos has something to do with C#; but, yes, this question here is way-off this forum's scope.

so here I'm trying to use proxies from a listView in my project. But I have no clue and have had no experiences in using proxies in C# before nore in any other form of anything haha.
So what I've got so far is a button to import a .txt file of "proxies" and it adds the items to a listView.
From there I'm wanting a loop in my proxy state so it runs through the listView of proxies.
I have no clue on what I'm doing here so would need some extended support here. In need of this for a college project.
Here is my post data.
CookieContainer cookieCon = new CookieContainer();
public string postRequest(string url, String postData, String Username, String Password)
{
try
{
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
request.Method = "POST";
request.CookieContainer = cookieCon;
request.ContentType = "application/json; charset=utf-8";
request.Headers.Add("Cookie", "devicecookie=146.200.41.147.1446567416483.346;");
request.UserAgent = "FireFox User Agent";
request.Headers.Add("Accept-Language", "en-GB,en-US;q=0.8");
request.Host = "www.collegename.co.uk";
request.Headers.Add("Accept-Encoding", "gzip");
request.KeepAlive = true;
byte[] byteArr = Encoding.Default.GetBytes(postData);
request.ContentLength = byteArr.Length;
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArr, 0, byteArr.Length);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
string source = reader.ReadToEnd();
return source;
}
catch (Exception ex)
{
if (ex.Message.Contains("401"))
{
}
}
return null;
}
Would appreciate it if you could give me some help here, thanks guys. I'm not looking to change a mass amount of my code but would appreciate some help.

Exactly what are you trying to do with these proxies? And more importantly, are you sure this is a good choice of college project?

It's to login and yes it's a good choice of college project because it's what we have been asked to do.

It's posting to the student login page, our project is to utilize proxies in a project so this is what I'm doing.

Can you show us the code where you load data into the listview? That is assuming you already have that code 
What kind of listview are we talking about? The one from WinForms? If yes, then you can "foreach" the Items property.

yeah i have this already coded where the proxies from the .txt file are listed in the listView.
Here is the code for that.
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "TXT files|*.txt";
ofd.Title = "Load Proxies";
var dialogResult = ofd.ShowDialog();
if (dialogResult == DialogResult.OK)
{
foreach (var line in System.IO.File.ReadLines(ofd.FileName))
{
if (line.Contains(":"))
proxies.Add(line);
proxyView.Items.Add(line);
}
}
|

You already 'run' through the items right there
Add a button to your form, and create a similar loop for the items in the listview;
foreach (var item in proxyView.Items)
{
System.Diagnostics.Debug.WriteLine(Convert.ToString(item));
}You can then reference any item in the listview and access its properties. Looks like each item is a single item, a text-string. I assume you want to call the other method and pass that then?
Where do the other arguments come from, like the name and password? Does the user have to enter those?

What I'm trying to do with the proxies that have been imported into the proxyView is use them in the request to login.
So for instance 3 proxies are imported for example
1.1.1.1:1738
2.2.2.2:1982
3.3.3.3:1234
I'm wanting each request to pull a proxy from the proxyView list and use it in the request that's being made.
The String Username and String Password are user defined they enter there username & password.
