importing dll's

[alankrita]

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.

try adding an "alias" to your declaration, this alias should have the same name as the main subroutine in your app (you may follow this with A [for ANSI] or W [for ASCII]). you then invoke the routine thru this alias. another workaround is using the DLLImportAttribute becoz with this you can specify the entry point during declaration.

you would call it this way: Private Declare Sub RunItFtrn Lib "DLL1.dll" Alias "runit" (ByRef ..., ByRef ..., ect...) but I would suggest reading this: http://www.codeproject.com/dotnet/intro\_fortran.asp
