How to add the Multiple Selected files from Openfiledialog in the RichTextBox

Question

Hi Guys...... I am new to this website and found it really good when it comes to problem solving and concept clearing... I am facing a problem.. I have used multiselect option of the openfiledialog but I am unable to write the result of this in a RichTextBox or a ComboBox or a ListBox or a TreeView... What I want to do exactly is that any of the above mentioned controls show the FileNames of the files that have been selected by the user in the openfiledialog.. Please Help !!! Chitkaran Singh

If you set the PictureBox's SizeMode property to PictureBoxSizeMode.StretchImage then the image you put into it will be stretched or shrunk to fit the PictureBox's own dimensions.

Oh thats really worked... Thanx Allan.. Just a simple think I wanna ask... When I click on the node and place the corresponding image in the pictire box it goes beyond the limits of the picture box.. So is there a way with which I can specity that irrespective of the actual size of the image it stays in the limits of the pictore box or the size that I specify.. ???

Perhaps the selected node has no child nodes and hence its Nodes property is null? But even if it has then you won't get anything meaningful from its ToString() method - just the name of the type which will be System.Windows.Forms.TreeNodeCollection or something like that. If the node which has been clicked has a label which represents the path of the image you want to place in the picturebox then I'd try: pictureBox1.ImageLocation = e.Node.Text;

private void treeView1_NodeMouseClick( object sender TreeNodeMouseClickEventArgs e) { pictureBox1.ImageLocation = treeView1.SelectedNode.Nodes.ToString(); //MessageBox.Show(treeView1.SelectedNode.Nodes.ToString()); } Gives an exception.. {Object reference not set to an instance of an object.}

Assuming you've set the RichTextBox's Multiline property to true then the code to list the file names within it would be something like this: DialogResult dr = openFileDialog1.ShowDialog(); if (dr == DialogResult.OK) { richTextBox1.Text = String.Join(
 openFileDialog1.FileNames); }
