I just installed J8. I have an icon jqt - cmd which takes me to Term. Run and Launch JHS takes me to Chrome. Here there seems to be no problem with link. All choices seem to work as they did in J7. However, if I close Chrome, the Term crashes and I must close it and close the program. Act

If I create a Shortcut with the following Target: "C:\Program Files\j64-801\bin\jconsole.exe" ide/jhs/core -js " init_jhs_'' " And Start in: "C:\Program Files\j64-801" That works for me. Of course you'll need to edit the above to use the path to your J8 install. On Mon, Mar 18, 2013 at 8:53 PM, L

The start jhs menu will be removed becuase it gave a wrong impression that jqt has connection with jhs but actually there are none. The jhs.bat batch file or shortcut should already serve the purpose of starting jhs. Пн, 18 мар 2013, Ric Tikkanz писал(а): > Linda, > There is nothing wrong with

This works well! I have jgt-cmd and jhs.bat as two icons on my desktop. They work independently. I can open the same file in each and switch back and forth with no issues that I have found so far. In less than 12 htours (including sleeping) I can paint a polar rose. Some individual scrip

Hi Henri, My observation about JfC was not meant to be negative. I think it could be understood that way. Just an observation that LJ seems gentler on the beginner - given that JfC is next in line in the help system after the Primer. I thought that indicated difficulty progression, with LJ being m

Has anybody used/created pinvoke C# signatures and used j.dll from .NET? If so, any feedback, how was that working? Also would there be interest in having pinvoke signatures someplace for others to use? For non-windows users out there, apologies. ---

I've called j.dll from C#, but that was years ago and I was using j602 (where you had to register j.dll as a COM server). http://www.jsoftware.com/jwiki/Guides/J%20VB.NET?action=AttachFile&do=view&target=Session.cs.txt My biggest frustration was error handling. In my implementation I only got the

I've always found COM too hard to use. And suspected that it had inherent issues that were not fixable by me, the end developers. I'll let you know how things go via PInvoke route, which I plan on trying sometime next week. If it works at all, not sure yet. On Mon, Mar 18, 2013 at 3:11 PM, Raul

Seeing if J can be used from C# via Pinvoke has been something I've been planning to try for awhile. COM itself is not to bad see: http://bakerjd99.wordpress.com/2010/05/28/a-c-net-class-for-calling-j/ but it's a deprecated technology because it's a royal pain in the rear in most corporate envi

IIRC pinvoke does not use COM. Instead it calls the C interface of a dll. there is an exmaple of calling j.dll in the folder examples/dll/ in J602. More complete header file for j.dll and how to call it is available in GPL j source. You may also find information in the jqt repos, in particular

Indeed, PInvoke doesn't go via the COM layer. examples\data\jdll.h is no longer in sync with the actual j.dll. Function names have changed, signatures, etc. I will be looking at jqt repo, thanks for pointing that out to me. On Mon, Mar 18, 2013 at 6:44 PM, bill lam wrote: > IIRC pinvoke does no
