KX Developer: show doesn't work

[vivo]

I just downloaded the KX Developer and Installed it. It works to do the computation, but it doesn't work to print messages.

In KX Developer, if I simply run "show 123", I will have the error "cannot write to handle 1. OS reports: the parameter is incorrect". Any ideas? My version is "KX Developer 1.5.4".

I did a test:

1. Downloaded developer-1.5.4-windows.zip

2. Extracted and ran install.bat

3. Opened the install folder and ran config\config.bat

4. Ran q launcher.q_

5. Opened my browser and ran show 123 using Ctrl+D

Works as expected:

Q version:

q)(.z.K;.z.k)
4f
2021.10.01

1. What OS are you on?
2. Are you following the same steps as above or different?
3. Does the issue remain after you restart Developer's underlying q process?

Thanks for your reply.

1. I'm using Windows 11 version 22H2 (OS build 22621.1555)

2. Yes, I used the 5 steps as mentioned by you and then I saw the error I mentioned. But I run `C:\q\w64\w64\q.exe C:\developer\launcher.q_` instead of `q C:\developer\launcher.q_` because I have 32-bit q and 64-bit q so I need to specify a 64-bit `q.exe`

3. Yes I tried restarting developer/browser/laptop and still have this problem

"Please attempt to load Developer without any changes to $QHOME/q.k or $QHOME/q.q"

Do you have any customisations in these files?

[vivo]

I didn't modify q.k. Meanwhile, I don't have a q.q file. When I downloaded the w64.zip file from the url provided by the free-trial-email, after unzipping the only available files I saw are q.exe and q.k, and there is no q.q.

Where is no problem for me to load workspace. If I run .z and .Q etc., there is no error.

It seems that the handle 1i is not connected to my console. If I run 1i"123", theorectically it should output 123, but at my KX Developer it just give me the same error "cannot write to handle 1. OS reports: the parameter is incorrect".

I have encountered the same problem as you, how did you solve it, how can I use show in developer？

[vivo]

Hi, I haven't solved the problem. Currently, I'm using a workaround as below:

1. Open another q-session in cmd, and then listen to a port using  \p, say port 9001

2. At KX Developer, create handle h1 which connect to 9001 using h1:hopen`::9001

3. At KX Developer, if you run h1 "show 2+2", you will see 4 at the q-session

This workaround is not very ideal, but still a bit helpful while debugging
