DataSet.WriteXml just write changed data?

[Harry]

Hi All,

I use DataSet.ReadXml read data from a xml file and DataSet.WriteXml
write data to the same xml file, it works fine. But I have a
question,if I just change a few of data in this dataset, then
DataSet.WriteXml will just save the changed data in the file,isn't it?
If DataSet.WriteXml doesn't work like this, how should I do in my
scenario, which read lots of data from xml file in the first time,
then just change a few of these data in running but must save changed
data back to file in time?

Thanks
Harry

Harry,

Use a database from which is one of the simplest ones MSDE

In my expirience is it when not you or your customers are all using a Strong
SA password a crime to install, however with this in the setup.INI file you
can pass that. What is not adviced by the way by Microsoft.
