Hello, how to add button that will create new folder base on current path?

Add at begin of your file: using System.IO;


Put following in your button click event:

string path = Environment.CurrentDirectory + @"\dirtocreate";
Directory.CreateDirectory(path);

i have add what you wrote but nothing is happening, i was able to add directory with this code:
System.IO.Directory.CreateDirectory("Y:\\Iskratrade12");

But that will only create folder in specific path....
i can put you my code here if you want to see it, i have one parent and one child,, this button is in child form , where i have listview for browse specific disk/folder...

Here is the code

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Collections;

public frmMDIChild1()
{
InitializeComponent();
//lista foldere i fajlove
folderCol = new System.Collections.Specialized.StringCollection();
napraviZaglavlja();
ListPogled(@"C:\");
folderCol.Add(@"C:\");
this.ListView1.ItemActivate += new System.EventHandler(this.ListView1_ItemActivate);

}

private void frmMDIChild1_Load(object sender, EventArgs e)
{

}


private void napraviZaglavlja()
{
ColumnHeader colHead;

//prvo zablavlje
colHead = new ColumnHeader();
colHead.Text = "Ime fajla";
this.ListView1.Columns.Add(colHead);//insert zaglavlje

//drugo zaglavlje
colHead = new ColumnHeader();
colHead.Text = "Velicina";
this.ListView1.Columns.Add(colHead);

// treco zalgavlje

colHead = new ColumnHeader();
colHead.Text = "Zadnja korekcija";
this.ListView1.Columns.Add(colHead);
}

// Clear the ListView. Note that we call the Clear method on the

If I understand your code correctly you have some kind of file browser and ListPogled[ListPogled.Count-1] contains your current path?

Than creating a directory would become something like this:

string path = ListPogled[ListPogled.Count-1] + "\\DirToCreate";
Directory.CreateDirectory(path);

ListPogled is a method and it is not valid in given context

You can try with Assembly.GetExecutingAssembly.Location instead of Environment.CurrentDirectory :

nothing :(

Sorry, were I wrote ListPogled i meant folderCol. I mixed them up.

Does that help?

yes i figured out now... it adds new folder, but it cant be seen on once only when i click back and enter current location it shows.. if you know what i mean..

i diint write it good for you to understand,, when i am on example: y:\fodler\(and in this path i add new folder) it is not showing. And when i reenter that path again (back and double klik tu enter same path) then it shows..

You mean it doesn't show up in your listview?

Than you should refresh your listview (refill it) or just add the new directory to the listview. The listView it self doesn't know about its contents is reflecting the content of a directory...

At least if I understand you correctly...

it shows in list view, but not after i click the button, i can't see new fodler, and when i go one step back and i return to current position where i was adding new folder in first place it then shows the new fodler.

Probably because in this case, like boothwine suggested, your listview is filled again ( may be onItemActivate event ).
So after your click call yourListPogled method to refresh the list view

how to do that?

nice , finally it is working, and it enter the new folder after click. Nice..

You could use a contextmenustrip, but you should start a new thread if you face problem to do that.

i will do some reading .. thank you for this.
