Where do i put .dlls for DLLImport?

[Guest Kingherc]

Well, I write a program for SmartPhones 2003 using VisualStudio2003.NET based on .net compact framework.

Now, I need to use some functions of a .dll (unnmanaged code - non .net). I figured I should use something like

_

Public Shared Function NameOfFunction() As String

End Function

. But although the above lines are correct, the debug throws a NotSupportedException. Maybe the .dll file cannot be found. I'd like to ask where do I put the .dll file to use it in such a way?? I just copied it in the folder but it still doesn't work. Also, I did the same for an application for Windows and it works! Maybe the .dll isn't meant for Smartphones? (though I tested only one function that returns a simple string).

Please some help. Where do I put the .dll files??

what dll file are you trying to access?

From my understanding (what little of it I have) the dll should just be in the app root directory, unless of course its a windows dll - in which case there is no need to do anything. - I think!!

I have tried to put it in the root directory but still it doesn't work... It's a dll called FreeImage. Anyways...

If you want to refer to the dll without the full path it should go in one of the following folders:-

The folder into which your app is deployed

The windows folder (this will be lost on a reset / power-off)

The StorageWindows folder

The root folder (again this will be lost on a power off)

Therefore if it is unique to your app place it in your application folder, else use StorageWindows

to:

\storage\windows\yourdll.dll (in Smartphone)

your .Net application will find it

but for Emulator I don't know how to do it.

I always just add DLLs to my Visual Studio project and let it take care of deploying my DLLs, and other resources.
