XmlDocument xmldoc = new XmlDocument();
string xmlfilepath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
//loading the file
xmldoc.Load(xmlfilepath + "/" + "enstatics.xml");
//returning the xmldoc
return xmldoc;
Creating XML file dynamically
//code for creating and saving default config public void create_config_xml_file() { try { //xml doc XmlDocument xmldoc = new XmlDocument(); //xml declaration XmlDeclaration xmldeclaration = xmldoc.CreateXmlDeclaration("1.0", "utf-8", null); //create root element XmlElement rootNode = xmldoc.CreateElement("myconfigdata"); xmldoc.InsertBefore(xmldeclaration, xmldoc.DocumentElement); xmldoc.AppendChild(rootNode); //adding more children to the root node //imageformatindex XmlElement ifiElement = xmldoc.CreateElement("imageformatindex"); ifiElement.InnerText = "1"; rootNode.AppendChild(ifiElement); //currentdirectory XmlElement currDirElement = xmldoc.CreateElement("currentdirectory"); currDirElement.InnerText = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments); rootNode.AppendChild(currDirElement); //fileprefix XmlElement fpElement = xmldoc.CreateElement("fileprefix"); fpElement.InnerText = "ISeeStand"; rootNode.AppendChild(fpElement); //filesuffixid XmlElement fsElement = xmldoc.CreateElement("filesuffixid"); fsElement.InnerText = "2"; rootNode.AppendChild(fsElement); //sequential XmlElement seqElement = xmldoc.CreateElement("sequential"); seqElement.InnerText = "0"; rootNode.AppendChild(seqElement); //sequentialvid XmlElement seqVidElement = xmldoc.CreateElement("sequentialvid"); seqVidElement.InnerText = "0"; rootNode.AppendChild(seqVidElement); //videncoder XmlElement videncElement = xmldoc.CreateElement("videncoder"); videncElement.InnerText = "WMVideo9 Encoder DMO"; rootNode.AppendChild(videncElement); //framesize XmlElement fsizeElement = xmldoc.CreateElement("framesize"); fsizeElement.InnerText = "800 x 600 @5.00 fps"; rootNode.AppendChild(fsizeElement); //framerate XmlElement frateElement = xmldoc.CreateElement("framerate"); frateElement.InnerText = "5.00 fps"; rootNode.AppendChild(frateElement); //getting appdata folder string app_path = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData); //saving that document xmldoc.Save(app_path+"/"+"enstatics.xml"); } catch (Exception exc) { MessageBox.Show("Failed to create the xml configuration file."+exc.Message); } }Modifying the XML file
The following code saves some info into the xml file accessing a particular XmlNode
//saving the image format index to the xml file try { XmlDocument xmldoc = MyStaticMgr.loadMyXMLDoc(); XmlNode formatIndexNode = xmldoc.GetElementsByTagName("imageformatindex")[0]; //setting the preferences to the xml node formatIndexNode.InnerText = (ImageformatComboBox.SelectedIndex + 1).ToString(); //now saving the xml file int result=MyStaticMgr.saveMyXMLDoc(xmldoc); } catch (Exception exc) { MessageBox.Show("Failed to save the preferences"+exc.Message); }Reading from XML file
The following code will demonstrate how to access a particular node of the xml file for a particular information//making a default choice try { XmlDocument xmldoc = MyStaticMgr.loadMyXMLDoc(); XmlNode formatIndexNode = xmldoc.GetElementsByTagName("imageformatindex")[0]; int format_index = int.Parse(formatIndexNode.InnerText); //now setting that index to the combobox ImageformatComboBox.SelectedIndex = format_index - 1; } catch (Exception exc) { string messageBoxText = exc.Message; string caption = "Exception Occurred"; MessageBox.Show(messageBoxText, caption); }XmlDocument xmldoc = MyStaticMgr.loadMyXMLDoc();//now saving the xml file int result=MyStaticMgr.saveMyXMLDoc(xmldoc);using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Xml;using System.Windows.Forms;namespace ISeeStand{ public static class MyStaticMgr { //code for loading the xml document public static XmlDocument loadMyXMLDoc() { XmlDocument xmldoc = new XmlDocument(); string xmlfilepath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData); //loading the file xmldoc.Load(xmlfilepath + "/" + "enstatics.xml"); //returning the xmldoc return xmldoc; } //code for saving to the xml file public static int saveMyXMLDoc(XmlDocument xmldoc) { int saved = 0; try { string xmlfilepath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData); //loading the file xmldoc.Save(xmlfilepath + "/" + "enstatics.xml"); //yes the file is saved saved = 1; } catch (Exception exc) { string messageBoxText = exc.Message; string caption = "Exception Occurred"; MessageBox.Show(messageBoxText, caption); } //returning the result return saved; } }}Step-1:Loading listview items::
The following code loads the items to listview control.
protected void load_courses()
{
//code for loading the courses
try {
OleDbConnection conn = new OleDbConnection(StaticData.connection_string);
conn.Open();
string select_courses = "select * from Course";
OleDbDataAdapter oda = new OleDbDataAdapter(select_courses, conn);
DataTable dt = new DataTable();
oda.Fill(dt);
//databinding to the listview
TestlistView.Items.Clear();
for(int i=0;i < dt.Rows.Count;i++)
{
DataRow row = dt.Rows[i];
ListViewItem lvi = new ListViewItem(row["CourseNo"].ToString());
lvi.SubItems.Add(row["CourseID"].ToString());
lvi.SubItems.Add(row["Credit"].ToString());
TestlistView.Items.Add(lvi);
}
}
catch (Exception exc) { }
}
private void Form1_Load(object sender, EventArgs e)
{
//code for loading the courses
load_courses();
}
Step-2:Handling the right click event on listview items:
private void TestlistView_MouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
Point pt = TestlistView.PointToScreen(e.Location);
contextMenuStrip1.Show(pt);
}
}
Step-3:Handling context menu strip event
private void contextMenuStrip1_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
{
if (e.ClickedItem.Text == "Upload")
{
MessageBox.Show("Upload started for:" + TestlistView.SelectedItems[0].Text);
}
}
Thats how we can use right click event to show a context menu strip and handle menu strip click events.
