This may seem simple to most, so hopefully I'll get a response.
We're working on keeping soldiers safe from IED's in Iraq and I have been
stuck on this problem for two days.
I have a source file. From that file, I select a hyperslab, 250x250 from it
and place it into a 2D array data[250][250]. I do some math with the array
and then I need to output the array to another HDF file.
The problem is that I can not for the life of me get it to create a new file.
I want to create a file that is the size of the original input file
(6000x4000) and fill in the data one hyperslab at a time (250x250).
I'm using C++ and Visual Studio 2005. Any suggestions? If someone could
write some pseudo code, I can handle the rest, I just don't even know where
to start
Do I have to create a dataset that enables chunking?
Do the chunks have to be the same size as the array I want to print?
Does it need to be an extendible dataset? (I don't see why, it's always a
fixed size 6000x4000 [or larger])

Hmm, have you seen the HDf5 tutorial and example code web-pages? Here's the URL:
