 |
|
I have been able to create and use a "Win32" dll with EXPORTALL set in Project-->Properties-->Linker Options.
However, how I do not see how to do that with a .NET dll project. How do I set EXPORTALL for a .NET dll in Visual Studio? |

Everything is exported anyway. There is no switch because the attribute cannot be switched off.
If you were writing C# code then you could make your fucntions private or public. In .NET FTN95 all external routines are public |

Well, unfortunately I must be missing something, I am not getting anything exportable. When I run the vb.net code calling the .NET FTN95 dll it gives the following error message when accessing the Fortran function:
"EntryPointNotFoundException was unhandled"
I am using the same code from the help file. Again, it worked for the Win32 dll, but not for .NET FTN95 dll
When I use the trial version of "Anywhere PE Viewer" it shows the following:
C:\WINDOWS\F95Net.dll
The image does not export any functions
For the Win32 dll it shows the following:
C:\WINDOWS\F95.dll
Export table
F (Ordinal: 1, Entry Point RVA: 1000h (4,096))
Here is the Fortran code used in both:
| Code: |
F_STDCALL FUNCTION F(X)
INTEGER F,X
F=X
END
|
and here is the vb.net code
| Code: |
Public Class Form1
Private Declare Function F Lib "F95Net.dll" (ByRef lnr As Integer) As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim x As Integer
x = F(3)
TextBox1.Text = CStr(x)
End Sub
End Class

Here is the buildlog.txt output, I tired for both .NET 2.0 and 3.5:

Ok, I found the solution in the help file. Wow, it was really hidden under Visual ClearWin-->Getting Started. There you will find a link to a BEAUTIFUL sample called "Calling Fortran from .NET - A Simple C# Form".
It should really be called "Calling FTN95 .NET dll from .NET - A Simple C# Form"
Anyway, this is perfect, and should be easier to find. |
