i work with webbrowser for showing simple text. i am in situation where i want that when user drag any file on webbrowser control then i want to show a icon for that file and one progressbar and one button programmatically. i manage to show file associated icon ob richtextbox just like using System.Drawing.Icon.ExtractAssociatedIcon(string filePath)
here is the code for handling file drag drop on richtextbox like below one
public Form1() { InitializeComponent(); richTextBox1.AllowDrop = true; //richTextBox1.EnableAutoDragDrop = true; this.richTextBox1.DragEnter += new DragEventHandler(richTextBox1_DragEnter); this.richTextBox1.DragDrop += new DragEventHandler(richTextBox1_DragDrop); } void richTextBox1_DragEnter(object sender, System.Windows.Forms.DragEventArgs e) { if ((e.Data.GetDataPresent(DataFormats.FileDrop))) { e.Effect = DragDropEffects.Copy; } } void richTextBox1_DragDrop(object sender, System.Windows.Forms.DragEventArgs e) { //Image img = default(Image); //img = Image.FromFile(((Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString()); //Clipboard.SetImage(img); //this.richTextBox1.SelectionStart = 0; //richTextBox1.AppendText("Hello"); //this.richTextBox1.Paste(); /* Dim img As Image = Image.FromFile(fname) Clipboard.SetImage(img) RichTextBox1.Paste() */ string strFilePath = ((Array)e.Data.GetData(DataFormats.FileDrop)).GetValue(0).ToString(); Icon oIcon= System.Drawing.Icon.ExtractAssociatedIcon(strFilePath); Bitmap myBitmap = new Bitmap(oIcon.ToBitmap()); Clipboard.SetDataObject(myBitmap); DataFormats.Format myFormat = DataFormats.GetFormat(DataFormats.Bitmap); richTextBox1.Text = ""; if (richTextBox1.CanPaste(myFormat)) { richTextBox1.Paste(myFormat); richTextBox1.AppendText(" " + System.IO.Path.GetFileName(strFilePath)); } else { MessageBox.Show("The data format that you attempted site" + " is not supportedby this control."); } }
here is one image link for your visualization purpose http://i.stack.imgur.com/5oRkt.png
