Using .NET library

[Marc Vanzegbroeck]

Hi,

Is is possible to use a .NET library with FWH? Or is it better to create a seperate EXE-file compiled with the .NET library, and transfer the data with a text-file.
A want to use a .NET library file that generate drawings. My program give the correct data to create it.

Thanks

Marc,

You may review FiveNet and the technique it uses to manage .NET from Harbour:

I am migrating the project to bitbucket:

Marc,

Please try it again, it should be ok now

FiveNet source code is very simple: We create a .NET DLL that we register and we manage from a Harbour application.

When we need some .NET value from the Harbour app, then we use a C DLL that access the code from the EXE.

Antonio,

if I understand correctly, I need to create a .NET exe with my function to generate my drawings, and call a function from the harbour application.

Marc,

A .NET DLL, and then use the DLL from the Harbour app

In FiveNet makefile you can see how the DLL is created from a C sharp file:

Code: Select all | Expand

fivenet.dll : fivetech.cs
   c:\Windows\Microsoft.NET\Framework\v3.5\csc /out:samples\fivenet.dll /target:library source\cs\fivetech.cs
   c:\Windows\Microsoft.NET\Framework\v2.0.50727\regasm samples\fivenet.dll /tlb
 

Also, the DLL needs to be registered:

FiveNet\samples\register.bat

Code: Select all | Expand

c:\Windows\Microsoft.NET\Framework\v2.0.50727\regasm fivenet.dll /tlb

Marc,

From FiveNet/source/prg/fivenet.prg this init procedure creates an OLE (.NET) object:

Code: Select all | Expand

init procedure FiveNet

   local bError

   if oFiveNet == nil
      try
         oFiveNet = win_oleCreateObject( "FiveTech.FiveNet" )
      catch bError
         wapi_MessageBox( 0, "Can't create object 'FiveTech.FiveNet'",;
                          "Please use register.bat", MB_ICONEXCLAMATION )
      end
   endif

return

[Antonio Linares]

In other words:

Once the DLL is registered we can instantiate an OLE object to manage the DLL from the Harbour app

Antonio,

If I run go.bat, I get :

C:\_vmsdata\FWH\Fivenet>go

C:\_vmsdata\FWH\Fivenet>if not exist obj md obj

So everything looks fine, except the 2 last lines. He can't find ftsnet.obj, and ftsnet.tlb.

Is that an error, or is this normal, because in the MAK-file, I see

ftsnet.dll : ftsnet.c
$(BCDIR)\bin\bcc32 -c source\c\ftsnet.c
$(BCDIR)\bin\ilink32 /Tpd $(BCDIR)\lib\c0d32.obj ftsnet.obj, samples\ftsnet.dll,,$(BCDIR)\lib\cw32.lib $(BCDIR)\import32.lib

@del samples\ftsnet.tlb

Before i have tried it with an old version of xharbour and got an error.
Now I tested it with Harbour and BCC7, and it's working!!!

Thanks

[Antonio Linares]

very good

Antônio,

Do you know if is possible to integrate FWH with this https://www.signfiles.com/signature-library/ ?
Could you help us ?

[Antonio Linares]

Vilian,

Why don't you contact them for a C compatible DLL version ?

That may be much easier

[vilian]

Ok,

I will ask them.
