Windows Application wierdness

Hdf-forum archives
1

I have been trying to get an array type implementation to work in a packet table dataset under .Net. And it's been bedeviling me. I have a simple test application that creates the packet table dataset. But when I move the same code over to my application the H5PTcreate_fl call fails for unknown reasons. The HDF5 output goes into a black hole & I can't debug the code either... so it's a black box to me.

Anyway, I finally chased down the difference. When I build the application to output as a "Console Application" it works. When it is set to a "Windows Application" (as my app is), it fails.

My only thought is that HDF5 is pushing some message to the console and that's causing a failure. But it isn't a problem with many other calls that I've made (and even failures that would be writing messages). So that doesn't quite jibe.

Does building the app as a Windows Application turn on __stdcall by
default? You probably have to use __cdecl with HDF5.

Wait, you are using .NET so that doesn't make sense. I was thinking of
Win32 projects.

Which language are you using? Which version of Visual Studio? Which
binaries are you using?

Dana,

I'm using C# with VS 9 and HDF5 1.8.3.

FWIW, I tried the same thing but with a H5D, and it didn't fail as a "Windows Application". Since Packet Tables and Datasets are somewhat interchangeable, can I just create it as a dataset and reopen it as a PT? I've had to do the reverse for some features (Attributes & Dimension Scales). But creating as a dataset and adding data as a packet table makes me nervous.

Can you send me some minimal code that demonstrates the problem? Something
where I can switch between a Windows and console app and get the behavior
you see would be very helpful.
