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,
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

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 :

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\ilink32 /Tpd $(BCDIR)\lib\c0d32.obj ftsnet.obj, samples\ftsnet.dll,,$(BCDIR)\lib\cw32.lib $(BCDIR)\import32.lib

@del samples\ftsnet.map
@del samples\ftsnet.obj
@del samples\ftsnet.tds
@del samples\ftsnet.tlb

Now I tested it with Harbour and BCC7, and it's working!!!

Vilian,
Why don't you contact them for a C compatible DLL version ?
That may be much easier
