I try reading "Language Reference 401.pdf" on the download page.
Now I know how to add a value into the second column by using the "ListboxSetCellValue bid, row, col, val" command

• bid: Field ID
• row: What row you want to insert a value
• col: What column you want to insert a value
• val: Message you want to be insert

Set Heading text by using the "ListboxSetHeading bid, col, val"

• bid: Field ID
• col: Column you want to set the heading
• val: Text you want to set

Get the currently selected row by using the "ListboxIndexFN(1)" command
usage: Put ListboxIndexFN(1) into num

That's all I know for Today.

Hey, Developer.
Can you improve the HyperNext 4 Documentation? (Guide > Overview)
Because in HN4 Docs. It didn't explain everything. Such as didn't tell the meaning of parameters, Example of command usage, etc.
I know now, you're focusing on developing HN5 and will never add more features into this HN4 but please improve the documentation.

Thank you for your post as it has really helped clarify things.

A big problem with updating the inbuilt HN4 guide is that its made using a text to binary parser that is quite primitive, has bugs, and is tedious to use. I wrote it nearly 20 years and never got around to fixing it.

I'll do my best to answer any questions posted here. Topics here help other HN users and they'll probably make their way into the HN5 help.

Please feel free to ask any questions, although often any code I'll provide will only be brief snippets.


HN5 Help

The HN5 help is based on that in HAC(HyperNext Android Creator). HAC's was much better than HN4 as it was friendlier, using a CHM file that supported links and images, and had a better index. However, HAC used the external MS Windows CHM viewer utility.

HN5's inbuilt help system can already load the HAC help CHM file, display it, and is searchable. It works cross-platform as it use Free Pascal code.

The process of converting HN4 help text into a CHM file for HN5 is now underway.  lt is being updated, and improved with suggestions from previous posts here, and will available for download as help for HN users.

By the way, it looks easy to add some new HN commands so users can display their own CHM help files etc in HN5.


Note, I'm using a HelpNDoc to create the CHM and PDF files. They is also have fully functional free version available (for non commercial use only).

Thank you for asking.

Actually I don't know for certain. Although most of the conversion is quite easy, the GUI functionality is much more complex.

I'm using Libre Project to keep track of things but it doesn't give a timeline, just a rough percentage of work needed for each module, subroutine, function etc.

HN 5 Creator is still not yet capable of fully running the Chart Demo project.
It can compile most of the scripts into runtime code but the Runtime Engine still needs a few weeks more work.

The GUI, card designer, and control dragging all need more work - yet another few weeks.

Then there is the testing and debugging before release.
The Windows OS version will be released first, followed by Linux.
OS X needs a lot of work, especially to run on OS X Catalina.

Although the current version of HN 5 runs on both Windows 7 and Lubuntu, no OS X versions has even been built yet.

Once the Chart Demo is working smoothly, then HN 5 Creator can be released, and no doubt lots of bugs will show up.

HN Player V5 will be released at the same time as HN Creator.

HN Developer creates HN plugins, but should not need much work as its very similar to Creator, except for some GUI differences.

Please note, these are all alphas.
 

Hello,

Unfortunately the HN command to launch a program/file cannot send parameters to the target.

However, a work-around is to create a simple batch file with HN and then use this to launch the target with necessary parameters.

Attached is a very basic project that converts a video using FFmpeg on Windows X64 - the download link is at the bottom of this post.

The project just has one button and one field.
The location of FFmpeg is hardcoded in the script, and the final video is called Video1.mkv
The video to be converted is selected via a dialog box.

Note, the video source path has " (quotation marks) appended around it,  in case the full path contains spaces.
I didn't do this for the converted file path as it is just saved to the project directory.


Most of the code just displays information into field 1 as to aid debugging.

Also, FolderItemLaunch(fvar,1) executes the FFmpeg in the foreground to aid debugging.
Just use - FolderItemLaunch(fvar,0) to launch it in the background.

Local fname,fvar,fdetails,ftypes,fpaths,fnames,fextens
Local fhandle
 
Local sourcePath

Clear field 1

@ --- Get file ---
Put '--- Get file ---' after field 1
FileAskFilter(fname,'',fhandle,fdetails,ftypes,fpaths,fnames,fextens)
Put fname after field 1
Put line 9 of fdetails into sourcePath
Put sourcePath after field 1


@ --- Create batch file ---
Local batchname
Put ' ' after field 1
Put '--- Create batch file ---' after field 1

Put MyDirectoryFN into batchname
Append FolderSeparatorFN onto batchname
Append 'mybatch.bat' onto batchname
Put batchname after field 1
OpenTWriteAbs(batchname,fvar)


@ --- Build batch file ---
Local commandLine
Put ' ' after field 1
Put '--- Build batch file ---' after field 1
WriteTLine(fvar, 'ECHO OFF')
Put 'C:\ffmpeg-win64\bin\ffmpeg.exe -i ' into commandLine
Append '"' onto commandLine
Append sourcePath onto commandLine
Append '"' onto commandLine
Append ' -c copy ' onto commandLine
Append 'Video1.mkv ' onto commandLine
Put commandLine after field 1
WriteTLine(fvar,commandLine)
WriteTLine(fvar, 'PAUSE')
CloseTWrite(fvar)


@ --- Run batch file ---
Put ' ' after field 1
Put '--- Run batch file ---' after field 1
FolderItemGetAbs(batchname,fvar,fdetails,ftypes,fpaths,fnames,fextens)
FolderItemLaunch(fvar,1)
Put 'DONE' after field 1


 

Here is a brief progress report on HN5 development for the month of August 2020.

The aim is to get the Chart demo project running inside HN5 Creator IDE.

The development is being carried out on a Windows 7 x64 machine with regular testing of HN5 on Linux(Lubuntu).

The development language is Free Pascal which should ensure HN5 will be able to run on a variety of Operating Systems, both newer and older versions. The main targets being Windows, OS X and Linux.
