PNG Image-related error message.

[Cyberbeard]

Hi,

Whenever I try to test something on my phone, this message shows up:

'An exception of type 'System.ArgumentNullException' occurred in Microsoft.Xna.Framework.Graphics.ni.dll but was not handled in user code

If there is a handler for this exception, the program may be safely continued.'

If I remove .PNG images from the project, it suddenly works.

Why is this happening, and how do I work around it?

Thanks!

EDIT: Solved it, you may delete this thread.

Can you tell us (and me in particular) what it was?

Can you tell us (and me in particular) what it was?

I wish I could. I've run into many challenges in the last week while learning the XNA exporter, so this is one drop in an ocean.

But I can say that many of the troubles I ran into were caused by saving the XNA project incorrectly, trying to debug the project while it was still open in an old version, and silly things like that. So I probably solved it by simply doing the process correctly.

... and btw, my process is:

* Save the game as an XNA Phone Project in MMF, into a folder where I keep my work-in-progress XNA project (simply 'replace' the old version with every new iteration of the game).

* Edit the .csproj file of the project (found easily by searching the folder for csproj) as recommended in this thread: http://community.clickteam.com/showthread.php?t=73925

* Open the project in MS Visual Express for Windows Phone (free if you register).

* Run it on my device.
