Take a look at the classes in the System.Xml namespace especially XmlDocument, XmlTextReader and XmlTextWriter.

Hello,
You could use an ArrayList or Hashtable and Add another ArrayList or Hashtable or ImageArray to each member.
All the best,

Hi,
I have to store a list as an external file of part codes and corresponding descriptions for later retrieval by other applications. What's the best way of doing it?
Each entry in the list consists of two strings, a part code and a description. I could just write to a text file and read from it again or should I use XML? Anyone have any ideas or examples of how to implement such code?
Thanks

Personally, I always favor XML over a plain text file. First, you can define an additional schema that allows you and other applications to easily validate whether the XML file contains data in a valid format. Second, you can use XPath to easily lookup the description for a part code. Finally, you are probably able to use the XmlSerializer class to easily create the Xml file in your application; depends on the way the you implemented the list to be stored in your application.?

Use XmlTextWriter.
For part key pairs, try this:
<code>XmlTextWriter </code>writer = new <code>XmlTextWriter</code>(_PartsListFilename, null);
writer.<code>Formatting </code>= Formatting.Indented;
writer.<code>WriteStartElement</code>("parts");
foreach ( <item> )
{
writer.<code>WriteStartElement</code>("part");
writer.<code>WriteElementString</code>("Code", <item>.Code);
writer.<code>WriteElementString</code>("Description", <item>.Description);
writer.<code>WriteEndElement</code>();
}
writer.<code>WriteEndElement</code>();
writer.<code>Close</code>();

Hi,
I hope someone can help.
I have to import some data from a text file into a database. The text files are loaded into a datagrid to be previewed and validated before being imported.
There are some conditions to the import, each child record must have a pre-existing parent record before it will be imported etc. The validation is handled in a stored procedure.
What I need to do is return all of the values that have failed to import in a collection.
public ItemEventCollection failures = null;
...
public ItemEventCollection EventImport(SecurityContext sc, ItemEventCollection EventCollection)
{
if (EventCollection != null)
{
foreach (ItemEvent itemEvent in EventCollection)
{
try
{
ItemEventInsertCommand.Execute(DataAccessManager(sc), itemEvent);
}
catch
{
failures.Add(ItemEvent);
}
}
}
return failures;
}
If I step through the code, failures always has a count of 0 when I know there are rows failing the import conditions. I need to add them to failures then pass it back to a datagrid.
How?
Do I use the out keyword or simply return the ItemEventCollection, I'm really stumped on this one, please can someone help?
Best regards
Scott

How is it possible if an object exists?
At present I have a code similar to this line:
//This retrieves the object...
objectData = MethodName(Name)
If the object does not exist, it goes to the catch statement.
How can I just check if it exists so that it does not go to the catch statement?
Something like:
if (MethodName(Name) not null)
{
}
else if (MethodName(Name) == null)
{
}
Thanks

if(objectData != null)
{
//do your codings here
}

I would like to check something like:
if (methodname(name) != null)
Is this possible?
|
|
|
|
|
yes it is possible

Yes, but only if the returning value of MethodName is a nullable object. If not your codition is always true.
Post the snippet of MethodName...

Mark

What is "MethodName" doing?
