Usb pinvoke issue..was previously working.

[Enrique Romero]

hi,
I previously had C#2008 express + SQL2008 + USB drivers installed, working. I switched laptops and upgraded to C# 2010 with the same SQL 2008 and same USB drivers. I'm now getting the following error:

PInvokeStackImb alance was detected
Message: A call to PInvoke function 'Central_xxxxxx !usb_api.usb_in terface::_MPUSB Open' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

I don't see what's changed..could it be something in C#2010? or perhaps .NET 4.0?

Thanks in advance,
Enrique

The error message sounds like a driver or DLL is a different version then it thinks it should be using

Hi Plater,
I've doubled checked the .dll versions and they both are identical. Something is being satisfied on the USB end. I have a couple of LED alternating on/off. I'm thinking, maybe dl C# 2008 and trying,just to match apples to apples. If anyone has any other suggestions please advise.

Tks,
ER

Hi Guys,
Ok I installed C# 2008 express on the new laptop.
Ran my program and all is working fine. It's has
to be something in C# 2010 express! How does one
notify MSN with these type of issues?

Cheers,
ER
