Creating a Windows Application to view Images

Question

Hi I have images from a horse show that I was recently a part of and wanted to create a C# Windows Application that will allow me to do this. I wanted to put the images into a list box and but I wanted to pick them up from my images folder on the computer. I'm using VS 2010 and I've done some programming at school but just need a little help if anyone would be so kind? I remember that I have to use the directoryinfo object to pull the images from the folder but then i'm getting stuck. Could someone help me please?

First using System.IO; private void bttnOpen_Click(object sender EventArgs e) { if (folderBrowserDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK) { textBox1.Text = folderBrowserDialog1.SelectedPath; getPics(folderBrowserDialog1.SelectedPath);// getl list of files } } public void getPics(string fPath) { foreach (string file in Directory.GetFiles(fPath)) { if (checkIfimage(file))//check if file is image { listBox1.Items.Add(file); } } } public bool checkIfimage(string fname) { bool isImage = false; string extension = Path.GetExtension(fname).ToLower(); if (extension == .jpg | extension == .png|extension==.bmp) { isImage = true; } return isImage; }

Here's my sample Note - you will have to proportion the picturebox to suit images

Hi Thanks for the reply When I'm trying this i get the error 'Error 1 The name 'folderBrowserDialog1' does not exist in the current context' and it doesn't pick up the images from my C:\Pictures\Images folder either. The listbox is just empty. The names that I entered into the listbox are there but when I select one and go to open nothing happens. Below is what my form looks like but nothing happens when I click on any of the options.
