Hi there,

I have an application where i want to save the current state of some objects to a file and then i want the application that file to be assosiated with my application so that when i double click on that file, my app will open and read the info from that file to retore the state.

Currently i'm simply using the XmlSerializer to serialize a wrapper object and save it to a xml file on my HDD.

Any suggestions as to how i would be able to use that created file to open my app?

Sorry, i'm pretty new in the c# environment and I'm not sure how to search for something like this.

Thanks

You could use a shortcut
to start your app with an XML file as parameter... :)

Thanks alot it can help me for now but i cant do that for every session i save - eventually there will be many.
I want the app to work like a word doc, for example, where you open the .doc file and it opens MS Word. I will create my own file extension e.g. *.pop

Thanks!
I didn't know that when you open a file with your c# app, the filepath is passed to the application as a parameter.
Got that sorted out thanks!

Now I would like to know how to change my Program and Access Defaults programmatically when i run the app for the first time or install it...

i get the basic idea - basically just adding the extention and description etc to HKEY_CLASSES_ROOT in the registry - altough c++ is way before my time so the syntax screws me around a little.
I see you can also do this when publishing a clickOnce app (Publish>Options>File Associations). that will be fine for me for now.

cool. thanks for your replies

OK :)
Try to change your output extension
from .XML to, for example, .YourAppSettings
and associate the new extension with your application by Explorer :)
