Re: v15 DLL Plugin Issue

[Douglas Cryer]

Many thanks to everyone who input into my issue.  I have eventually found a 
solution.

I wrote a VBScript that calls the ActiveX object and that works now.  Initially 
it was not working when I tested it on the desktop but it works from within 4D 
v15.

Here is my crude understanding of what was happening:
When the script was double clicked it is running WScript and given the platform 
it is probably running the 64 bit version which could not create the ActiveX 
object.
When I write and run the script file from within 4D I am using CScript and this 
is working.  I am assuming because it is running 32bit version of CScript.
 
What ever the reason I now have a working solution with the COM object and 
LAUNCH EXTERNAL PROCESS

Thank you everyone who gave input as knowing I had other minds on it helped 
keep me sane.

Regards,  Dougie

Re: v15 DLL Plugin Issue

[Keisuke Miyako]

I guess DLLTOOLSSW is the name of the 4DX, not the DLL it is linked to.
the mystery is why it "appeared to work with v15" initially.

even though DLL wizard is no longer available for unicode mode,
it was always possible to read public C APIs from a DLL using DUMPBIN.
then you could use LIBTOOLS and some text editing to create a LIB file for 
linking.
and call the DLL using standard Win32 APIs.
but it would be much easier if there were at least some header files or SDK to 
use that DLL.

Re: v15 DLL Plugin Issue

[Keisuke Miyako]

I see you already posted the DLL name.

it sounds like the plugin (DLL wrapper) is hooking to the non-unicode entry 
point (FourDPack).
v15 exposes the unicode entry point (FourDPackex).

I think you need to re-develop the plugin in unicode mode.

Re: v15 DLL Plugin Issue

[Douglas Cryer]

Timothy and Miyako,

Thank you for your input, I found the following based on your suggestions:

Under v13
The plug-in shows in the list as AddressX but in the explorer window as
DLLTOOLSSW
Version 1.0.1.0
Location “AddressX.bundle” in volume “C:” with a full path displayed with a 
popup menu.

Under v15
I see the plug-in called AddressX but the only information it shows in the 
explorer window is :
AddressX
Location “AddressX.bundle” in volume “C:” with a full path displayed with a 
popup menu.

Also the commands now appear below a sub section now called “Theme 1” instead 
of directly under the AddressX plug-in.

This does not give me any further clues.  Clearly v15 is reading the plug-in 
differently but that does not help me fix the issue.

Doug,

Check if it is enabled from 4D's Explorer like shown here:

Re: v15 DLL Plugin Issue

[Keisuke Miyako]

the command name tokenising in the method editor only proves that the RSR (or 
manifest,json) file is present.
whether a plugin is loaded or not is evident in the Explorer, plugins page.

Re: v15 DLL Plugin Issue

[Douglas Cryer]

Miyako,

Re:
unless the plugin is dynamically loading the DLL (LoadLibrary),
it should appear as disabled immediately because dependencies are resolved 
at startup.
if that is the case, you could use "depends" to see which DLLs are missing.

http://www.dependencywalker.com

If I understand you correctly you are saying that if there was a broken 
dependency then the plugin would not load.  If so,  I can rule that out because 
the plugin is loading.

On the clients machine I have put a very simple uncompiled database with two 
methods to test what happens.  I have copied it and lauched it separately with 
v13 and v15.  The converted (new style) plugin is installed in both.  In both 
the plugin shows OK in the method after re-parsing it (several times).

On the v13 copy the method runs and calls the plugin commands OK.

On the v15 copy the 4D just crashes.

what if you place the DLL right next to the 4DX?

I had tried this, although it made no sense doing it as the original path was 
set to the DLL in the original DLLWizard project.

Struggling…

Re: v15 DLL Plugin Issue

[Douglas Cryer]

Randy,

Re: Is it a path issue with how Windows is seamlessly running things out of the 
C:/ProgramData folder when your application is in C:/Program Files?

No I do not thank it is anything like that.  I thought it might be a 64bit vs 
32bit issue because the server was moved from v13 to v15 64bit but when I try 
the code on standalone v15 which is 32 bit the code crashes when it makes the 
call to the plugin method which works fine with v13.

Is there such a thing as a direct replacement for DLLWizard?
