sql Connection, datadapters and create datasets, so how can i now use this
datasets in other forms, i cannot find any examples on internet. also i

Hi Matej,

You can't share them within designer.
You'll have to pass references to another form.

Matej,
Normally what I do is to add a new Component (Project Add Component) to my
project, the put all the connection, adapters, commands and so on this new
component. I then add methods to the component to "simplify" the interface,
for example I may have a single Fill method that invokes Fill on all the
contained adapters...

Then from my Forms I can reference this component & use the part I need.

Note if you add the component to your form, each form will get a new
instance, its may be "better" to implement the Component as a singleton and
manually invoke the methods.

Using a Component gives you a visual designer without the overhead of an
actual form.

Hope this helps
Jay
