Hi all, 
Sorry if this is off topic, but when using adapters, one can reference the row and/or the dataset of the adapter. 
Traditionally, I've always worked with a datarow from the adapter, but I have read others code that utilizes the dataset.
Example:
`DataRow poRow = adapterPO.POData.POHeader.Rows[0];`  
 
VS

     PODataSet POData = adapterPO.POData;
     PODataSet.POHeaderRow poHD = (PODataSet.POHeaderRow)POData.POHeader[0];

Seems to me that they accomplish the same thing in the end, but I'd appreciate any further explanations of this!

PODataSet extends DataSet, just like POHeaderRow extends DataRow. All it is a Typed DataRow / DataSet. They are the exact same thing...
You don't have to cast POData.POHeader[0] to POHeaderRow it is already that type.
I recommend you use the typed classes because using quoted strings can lead to runtime errors.
With the typed data set you can do
```cs
adapterPO.POData.POHeader[0].PONum //typed class
//vs
adapterPO.POData.POHeader.Rows[0]["PONum"] //using the super class of DataRow, requires index access or name access error prone
//Both of the above lines are the same in terms of the output of the code, but the first one is much easier to work with
```
