Using C#: Unable to load DLL 'mapscript': The specified module could not be found.

[Eduard Witteveen]

Hello list,

While i tried to create an application which uses mapserver 
(http://hobu.stat.iastate.edu/mapserver/mapserver/build_output/4_6/full.zip) 
i get the error that it cannot load the DLL 'mapscript'.

I following steps were taken by me:
- Download 
http://hobu.stat.iastate.edu/mapserver/mapserver/build_output/4_6/full.zip
- Create a Console application in MS VS 2005 C#
- Add the csharp/examples/drawmap.cs to the project
- Add the csharp/mapscript_csharp.dll as reference to the project

The project builds succesfull

When i try to run the executable i get the following error:
> System.TypeInitializationException: The type initializer for 'mapscriptPINVOKE' threw an exception. ---> System.TypeInitializationException: The type initializer for 'SWIGExceptionHelper' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'mapscript': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
>    at mapscriptPINVOKE.SWIGExceptionHelper.SWIGRegisterExceptionCallbacks_mapscript(ExceptionDelegate applicationDelegate, ExceptionDelegate arithmeticDelegate, ExceptionDelegate divideByZeroDelegate, ExceptionDelegate indexOutOfRangeDelegate, ExceptionDelegate invalidOperationDelegate, ExceptionDelegate ioDelegate, ExceptionDelegate nullReferenceDelegate, ExceptionDelegate outOfMemoryDelegate, ExceptionDelegate overflowDelegate, ExceptionDelegate systemExceptionDelegate)
>    at mapscriptPINVOKE.SWIGExceptionHelper..cctor()
>    --- End of inner exception stack trace ---
>    at mapscriptPINVOKE.SWIGExceptionHelper..ctor()
>    at mapscriptPINVOKE..cctor()
>    --- End of inner exception stack trace ---
>    at mapscriptPINVOKE.new_mapObj(String jarg1)
>    at mapObj..ctor(String filename)
Which clearly contains the message:
System.DllNotFoundException: Unable to load DLL 'mapscript': The 
specified module could not be found. (Exception from HRESULT: 0x8007007E)

I tried placing the csharpt/mapscript.dll in the \bin\Debug\ folder and 
i placed it inside the c:\windows\system32\ folder, but i still receive 
the error.

I've tried to find more information about this message, but my best 
friend couldnt find anything about it.

How can i make this application run succesfully / where do i have to 
place the mapscript.dll(or more files?) ?


mvg,
