here are some functions that might come in handy
here is XML file before changes
Code:
<?xml version="1.0" standalone="no"?>
<ProgramSettings>
<Lingo>German</Lingo>
</ProgramSettings>
here are 2 lines of code, one to set a new value, and the other to read the value..
Code:
MessageBox.Show(myXML.setXMLNodeInXMLFile(Environment.CurrentDirectory + @"\settings.xml", "ProgramSettings", "Lingo", "Spanish"));
MessageBox.Show(myXML.getXMLNodeFromXMLFile(Environment.CurrentDirectory + @"\settings.xml", "ProgramSettings", "Lingo"));
here is the result
Code:
<?xml version="1.0" standalone="no"?>
<ProgramSettings>
<Lingo>Spanish</Lingo>
</ProgramSettings>
and here is the code
