What version of Elements are you using?

CBLink · August 23, 2018, 6:34am

I am currently using 10.0.0.2313. The same issue occurs with 10.0.0.2305

Hi,

I can’t reproduce above error.
can you check to what location is referenced Hydra?
it should to C:\Program Files (x86)\RemObjects Software\Hydra for Island\Bin\Windows\i386\Hydra.fx

another issue with this sample:
we have refactored Island and nowadays ToLPCWSTR was assemble declaration, so add to this sample this extension:

extension method String.ToLPCWSTR: rtl.LPCWSTR; public;
begin
  if String.IsNullOrEmpty(self) then exit nil;
  var arr := ToCharArray(true);
  exit rtl.LPCWSTR(@arr[0]);
end;

Hi,
removing and reinstalling the beat did at least resolve the reference issues.
Building the project directly after loading produces the following output:

when adding the extension at the end of the file:

Rebuilding the project produces this output:

not very promising,

can you try to use newest element build, like 10.0.0.2319?

CBLink · August 29, 2018, 3:01pm

Hi,
i tested with Elements 10.0.0.2319, still not possible to compile.
Please provide me with an exmaple, that can be compiled successfully.
Actually Elements works with all Examples without any Errors, except that the Hydra for Island Example cannot be compiled successfully.

mh · August 29, 2018, 3:15pm

Same linker errors, still, with .2319/.2321?

CBLink · August 29, 2018, 3:28pm

same Errorlist as above

EvgenyK · August 29, 2018, 3:30pm

if you recompiled ...\Hydra for Island\Source\Hydra.sln manually and specified Hydra.elements as reference instead of precompiled Hydra.fx, would it work?

mh · August 29, 2018, 4:08pm

Hmm, I can not reproduce this, latest Elements (not much changed since .232)1 and latest Hydra… Can I send you a newer Hydra build JIC?

CBLink · August 30, 2018, 5:19pm

Hi,
i could try to compile the source and adjust the reference.
Unfortunately, the folder does not contain the maintioned Hydra.sln file:

mh · August 30, 2018, 5:28pm

just open Hydra.elements. But first, try the new build I uploaded for you?

CBLink · August 30, 2018, 5:54pm

HI,
with this build, the plugin was compiled successfully without errors and warnings.
Great.
But when copying the *.dll and *.fx into the Mixed Demo \bin… Folder, the oxygene host does not regognize the Island Plugin DLL.
The VCLHost and FMXHost neither

mh · August 30, 2018, 5:56pm

Glad to hear

I’ll need to leave that one to Eugene to answer…

EvgenyK · August 31, 2018, 7:10am

these samples loads only .dll plugins:

procedure TMainForm.FormCreate(Sender: TObject);
begin
  //Load all plugin modules that match search pattern
  ModuleManager.LoadModules('*Plugin*.dll');
  //Show available plugin in a combo box
  ListPlugins;
end;

if you want to load island plugin into those hosts, add code into FormCreate method like

  ModuleManager.LoadModules('*Plugin*.fx');

CBLink · August 31, 2018, 8:12am

Please update the Mixed Mode Example.
If you offer Island Plugins, than your Demos/Exmaples should recognize and load/use them

EvgenyK · August 31, 2018, 12:31pm

The Mixed Mode sample works with visual plugins only.
Island supports non-visual plugins only.

CBLink · August 31, 2018, 3:01pm

Thank you for the hint.
Nevertheless, which out-of-the-box example can load and show Island Plug-ins.
i tried the Delphi Demo (FMXhost and VCLhost) which allows loading Visual and Non-Visual Plugins.
But could not load Island Plugins as well.

EvgenyK · August 31, 2018, 3:03pm

just add the same line into those hosts
