Memory problem

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hallo all,

I have a problem with the memory management of the compact framework.
Without a obvious reason the VB.NET program uses more and more memory which
ends with a system stop because there is no more free memory.

My program has a global dataset. If these dataset has changed data it will
be created a new temporary dataset with a changed data for updating a
database. After the updating the temporary dataset is not further necessary
and should be distroyed automatically.

I have made a simple test program showing the same behaviour.
These program has a global dataset with some changed rows in a datatable.
Then it calls a function with checks the dataset for modifications and creat
a new dataset, copies the changed rows in these dataset and gives the new
dataset back. That's all. The temporary dataset will not be used further.
Because I do not call "accept changes" each check finds changed rows in the
global dataset.
For checking the dataset contents I use a timer event.

Has everyone a Idea what I can do agains the increasing of the used memory?
