Hello,
\r\nI am trying to use DotNetZip with the TreeView control using checkboxes. I can populate the treeview with files from the file system but I cant grasp the concept of putting them in a zip file if checked.
\r\nThe following is my code for the treeview:
\r\n void PopulateNode(Object source, TreeNodeEventArgs e)
{
TreeNode node = e.Node;
if (node.Value == "Files")
{
node.Value = "~/";
}
String rootDirectory = Request.MapPath("~/", Request.ApplicationPath, false);
String fullPath = Request.MapPath(node.Value, Request.ApplicationPath, false);
if (fullPath.StartsWith(rootDirectory) == false)
{
// Mitigate against spoofed callback arguments
// Requested directory is not under root directory
return;
}
String[] dirs = Directory.GetDirectories(fullPath);
\r\n // Enumerate directories
foreach (String dir in dirs)
{
String virtualDir = node.Value.TrimEnd(_slashArray) + "/" + Path.GetFileName(dir);
TreeNode newNode = new TreeNode(Path.GetFileName(dir), virtualDir);
if (Directory.GetFiles(dir).Length > 0
|| Directory.GetDirectories(dir).Length > 0)
{
newNode.PopulateOnDemand = true;
}
node.ChildNodes.Add(newNode);
}
// Enumerate files
String[] files = Directory.GetFiles(fullPath);
foreach (String file in files)
{
TreeNode newNode = new TreeNode(Path.GetFileName(file), Path.GetFileName(file));
node.ChildNodes.Add(newNode);
}
}
Help would be much appreciated.
\r\nThanks

\r\nRegardless, it seems like you want to set up a button, with an OnClick event handler. Within the OnClick method, instantiate a ZipFile object. Then, walk the nodes of the tree, going through each one. For each node in the tree, if the checkbox is checked, then add the filename for that node to the ZipFile with zip.AddFile().
\r\nAt the end of looping through all the nodes. call ZipFile.Save().
\r\nIs that helpful?

Cheeso,
\r\n\r\n\r\n\r\n
Thanks for the reply. I appreciate\r\nyour help. Of course I am new to this I am learning .NET using C#. I am not too familiar with the Treeview and its properties. So here is my attempt:
\r\n\r\n\r\n\r\n
using (ZipFile zip = new ZipFile(Response.OutputStream))
\r\n\r\n{
\r\n\r\nforeach (TreeNode\r\nnode in MyTree.CheckedNodes)
\r\n\r\n{
\r\n\r\nif (MyTree.SelectedNode != null)
\r\n\r\n{
\r\n\r\nif (Directory.Exists(MyTree.SelectedNode.Checked)\r\n== true)
\r\n\r\n{
\r\n\r\n\r\nzip.AddFile(MyTree.SelectedNode.Value);
\r\n\r\n}
\r\n\r\n}
\r\n\r\n}
\r\n\r\nzip.Save();
\r\n\r\n}
\r\n\r\n\r\n\r\n
Now I am trying to\r\nkeep the directory structure as is when zipping as there will be multiple\r\nfolders and multiple files in them.
\r\n\r\n\r\n\r\n
I don’t think I am doing\r\nthis right would you mind helping me out.
\r\n\r\n\r\n\r\n
Thanks again,
\r\n\r\n\r\n\r\n

What you are doing seems ok to me.
\r\nYou asked for help. But what's the problem you're having?
