Hi, I am using the intel fortran 8.0 compiler.When i run the vb.net application,I get an error saying System.DllNotFOundException and that it is unable to load the dll.When i tried referencing the fortran dll from vb.net the error was that it is not a valid dll or com object.is there some configurations that i need to set before trying to import the dll. Thank u

hey guys, i realised what i did after i posted.so i just deleted it after i got the mails.and my question was regarding both vb.net and .net framework.so i posted my question on both the forums because i dint know where it fit right. sorry abt that again.

Hi, Thank you all for ur answers.I tried working it out but there still is some problem.I tried the dllimport method but i still have an error saying that the entry point has not been found.this was using salford fortran .i was just wondering if all fortran compilers are compatible with .net platform.when i used the intel fortran 8.0 compiler i was not able to reference the fortran dll as well.the error was that it is not a valid dll or com object.i guess it cudnt recognise the dll.is there anything i can do to get it right?? the dllimport code i used was _ Public Shared Sub xyz(ByRef x As Integer) End Sub call xyz(x) and in the fotran dll i wrote the following subroutine Dll2(x) x=x+1 ! Expose subroutine Dll2 to users of this DLL ! !DEC$ ATTRIBUTES DLLEXPORT::Dll2 !MS$ATTRIBUTES REFERENCE :: x end subroutine Dll2 this is just an example i was trying to get right. i need to get it right soon. thank u for ur help

Hi, Can anyone help me with importing a fortran 8.0 dll to vb.net.I have tried several times with the following code but get an error saying that the entry point in the dll was not found. I have a module in vb.net that contains the following code. Declare Sub runit Lib "C:\Documents and Settings\User\My Documents\Visual Studio Projects\Dll1\Debug\Dll1.dll" _ (list of arguements) where Dll1 is the name of the fortran project.and runit is the subroutine i am trying to call from .net. I dont know what to do.Is there any configurations that i must set before trying to run the program.
