Parse an IETF RFC 4180-compliant CSV File with Apex
While Salesforce does not natively generate IETF RFC 4180-compliant CSV files, for those who are trying to use email services or other code to process CSV files there may be an alternative solution.
Click here for blog post with code. Note: Reading the code becomes much easier if the code is copied and pasted into an editor like the Force.com IDE.
Parse a CSV with APEX
There are many tools to import CSV files, but if you need to work on multiple objects from the same file, you might need to do it in Apex. Here is a CSV parsing function that returns an array (lines) of string arrays (fields). Does not handle newlines in the content though.
public static List<List<String>> parseCSV(String contents,Boolean skipHeaders) {
List<List<String>> allFields = new List<List<String>>();
// replace instances where a double quote begins a field containing a comma
// in this case you get a double quote followed by a doubled double quote
// do this for beginning and end of a field
contents = contents.replaceAll(',"""',',"DBLQT').replaceall('""",','DBLQT",');
// now replace all remaining double quotes - we do this so that we can reconstruct
// fields with commas inside assuming they begin and end with a double quote
contents = contents.replaceAll('""','DBLQT');
// we are not attempting to handle fields with a newline inside of them
// so, split on newline to get the spreadsheet rows
List<String> lines = new List<String>();
try {
lines = contents.split('\n');
} catch (System.ListException e) {
System.debug('Limits exceeded?' + e.getMessage());
}
Integer num = 0;
for(String line : lines) {
// check for blank CSV lines (only commas)
if (line.replaceAll(',','').trim().length() == 0) break;
List<String> fields = line.split(',');
List<String> cleanFields = new List<String>();
String compositeField;
Boolean makeCompositeField = false;
for(String field : fields) {
if (field.startsWith('"') && field.endsWith('"')) {
cleanFields.add(field.replaceAll('DBLQT','"'));
} else if (field.startsWith('"')) {
makeCompositeField = true;
compositeField = field;
} else if (field.endsWith('"')) {
compositeField += ',' + field;
cleanFields.add(compositeField.replaceAll('DBLQT','"'));
makeCompositeField = false;
} else if (makeCompositeField) {
compositeField += ',' + field;
} else {
cleanFields.add(field.replaceAll('DBLQT','"'));
}
}
allFields.add(cleanFields);
}
if (skipHeaders) allFields.remove(0);
return allFields;
}

Google Maps API mashup for Leads, Contacts and Accounts

Subscribe related user to sObject record
Subscribe a related user to the chatter feed for a given record. Should work for any sObject that has Chatter Feed enabled, and a related user.
Class, test class and generic sObject for test class included.
This is a link to the shared archive in my google docs. It was the quickest way to do this for now. I may publish more details at a later date. Chatter Feed Class Archive
