I feel like I have been coming the internet for days with absolutely no result.
I have taken some web programming classes, and would like to learn some python, just because programming is wicked interesting altogether, and have run into a fairly large hurdle given my experience.
the problem is this: Python.exe (or is is more properly pythonw.exe?) v3.3.3, running on windows 8.1 used to launch fine. Typed up a simple program to roll various sided die, worked out well. Then I changed the key bindings for 'Run Module' from 'ctrl+f5' to 'crtl+alt+spacebar.'
As soon as I did this IDLE crashed and so did the shell. Now the process will not run AT ALL. I cannot access it through the desktop icon to go back and revert the settings. I also attempted to look at the .def files and change it from there but could not find the 'run module' command. It looked like all the key bindings in the .def files were for the shell.
When I double click, nothing, when I run as admin, nothing. run from the start menu, nothing. I uninstalled and re-installed, rebooted, everything low tech I can think of. Now i'm out of my element and could use one of you brilliant social programmers!!
I've found information about checking with some tool called 'Windows Process Manager' some stuff about what to do with the CMD prompt (something about a path problem ...it intuitivly sounds like I very well could have created a 'path problem' but I'm not 100% I know what that is exactly).
I'm sorry for the lack of links, the pages were farther back in my browsing history than I expected. Hopefully i'm not asking an instant many down vote question here, most of the resources online are for either an older version of windows, Lunix, or an older version of python (which is actually where the path problem hint came from)
Thanks any and all greatly for any time spend reading/answering.
Immensely appreciated.
Find file HOME/.idlerc/config-keys.cfg, where on Win7 HOME would be 'C:/Users/yourloginname', and delete the key binding or, if there is nothing else in the file or nothing you want to keep, the whole file.
If you were to run Idle from a console with python -m idlelib, you would probably see an error message. (Yes, you were probably running with pythonw, as when using the start menu or icon. This works better in 3.4.2 and I am working or more improvements.)
I do not know the specific reason for your crash. I set Zoom-height to --space, restarted, and it works, no problem.

Recently, I switched my OS to Ubuntu. I just started with collage and I have to learn pascal for my finals. But a problem occurred.
I installed Visual Studio Code and Pascal extension for it, but I am unable to run even a simple Hello World code. I wrote code, it saved automatically as .pas, but when I enter debug & run option in VSC it displays a message that says 'Open a file which can be debugged or run.', followed by 'debug' and 'run' buttons that I am unable to click and another message that says 'To further configure Debug and Run create a launch.json file.'
I am not even sure am I supposed to post questions such as this one on stackoverflow, but I sincerelly hope that someone could give me a hint on what to do. Solve this within Visual Studio Code or switch to another IDE (and which one would you recommend for Linux user) and pretend that nothing happened?
Thanks in advance.
I know this isn't an answer to "how to debug with pascal with vscode" but, perhaps you would find it easier to just use FPC / Lazarus (IDE) to do your work. While it doesn't have a dark theme, contrary to popular belief, that's not necessary to program.
The IDE is feature packed and allows for full code completion, debugging, etc... (everything you really need to do the work for school).
Additionally, you can use this open source tool to install everything you need for your platform in just a few button clicks (also allows for installing common library packages)
https://github.com/LongDirtyAnimAlf/fpcupdeluxe/releases
download release for your OS
under "FPC Version" & "Lazarus Version" select trunkgit (or stable for an older version)
click the "Install/Update FPC + Lazarus" button
Have you Installed Pascal extension which is available for code to smoothly run pascal code.
If you haven't then try installing this extension using,
Launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter.
ext install alefragnani.pascal
You can always check,
https://marketplace.visualstudio.com/items?itemName=alefragnani.pascal
to install and configure pascal in vscode.
I will direct you to the debugging page from the Visual Studio Code documentation that details how to use the debugger and configure a launch.json file. VSCode is a generic IDE so you need to give it some information about your project before it knows how to run the debugger. This is what launch.json is for.
If I could make a suggestion. When you're learning how to program, it's best to start with the basics. Write a small program in a text editor (VSCode is fine, or Vim, or Nano, or Notepad, or whatever). Save the file. Compile and run the program on the command line.
Once you put an IDE in the mix, you have to learn how to use that as well. If you're stuck on both parts, it can be hard to make progress. That said, it's good to learn how to use the IDE, and you should spend some time reading the documentation and working through some of the examples. It takes some time, but it will pay you back a thousand times when you can work more quickly.
I have a itcl/tk application that runs fine on Linux (and for the most part on Windows too). Have a frame where I packed an iwidgets::scrolledframe and within that an iwidgets::tabnotebook where two tabs were added.
Never have a problem on Linux, but on Windows (using Win7) often the 2nd tab is missing. Sometimes exiting and reinvoking the application on Windows and it will appear, but often it just never does. I have tried reorganizing code, inserted "update idletasks", to no avail.
Not sure if there are other tricks, or need to dig into itcl/tk installed code, or if could be a potentially a PC machine hardware issue.
Any ideas or suggestions of things to try will be graciously appreciated.
Turns out I appeared to resolve this via a strategically place update idletasks afterall. ;)
Intermittent Failures with webdriver.js
I am creating some webdriver.js* scripts to automate some time consuming test setup activities. However, when I run the script and do other things with my keyboard and mouse, I come back and find that, intermittently, a particular element cannot be found. And it's a different element each time.
When I run the same scripts and just watch them run, the scripts execute correctly.
Also, when I researched this potential problem, I came up with lots of stuff on using the mouse in webdriver scripts and problems with the click method itself but couldn't find anything to do with my issue. So I'm wondering whether I'm just doing something wrong here.
So What's The Question?
My question is: Is webdriver.js not meant to run like this? (that is, run locally while the keyboard and mouse are doing other things)?
Webdriver.py?
I don't remember having these problems when I used webdriver.py a few years back. iirc, I was able to run the scripts while the workstation was locked (via Win + L) though my memory isn't what it used to be ;)
I would use webdriver.py, however, no one else in our team knows python so I thought I would go webdriver.js since we all know javascript :)
Params: IE11, Windows 10.
* Also, when I say "webdriver.js", I mean the webdriver that is installed after following the steps here
I found that if I replaced the .click() calls with an equivalent .sendKeys() call (e.g. webdriver.Key.ENTER / webdriver.Key.SPACE) , this would get around the problem. I could even lock my workstation and the scripts would run without any problems.
I'm using Unity3D and I'm having issues with the keyboard when I 'build' the project.
When I run the game within the Unity Editor, the input works fine. However, when I build the project and test it, I have no directional input whatsoever. The mouse works fine, the game registers keystrokes (the Esc key works), but the player won't move.
I'm using Input.GetAxisRaw("Vertical") and Input.GetAxisRaw("Horizontal")
I researched the issue on the web, but I'm still stucked. The only solution I found (in various links) mentions a problem with DirectInput and states that you should remove the key "Input" from [HKEY_CURRENT_USER\Software\Unity\Player], in the Windows registry, but that doesn't seem to work for me.
Has anybody else fought this problem? Any working solutions? Am I doing the registry trick wrong?
You should check out Input Manager in Edit->Project Settings-> Input. Have you tried using GetAxis instead of GetAxisRaw? I also suggest using, eg: Input.GetKey(KeyCode.A) and etc.
I've figured out what was troubling me.
Input.GetAxisRaw("Vertical") and Input.GetAxisRaw("Horizontal") were fine the whole time. Somehow, there was some code in the script that in the Editor worked just fine, but when running as standalone gave me a calculation equal to 0 (it depends on the Delta Time, so I assume that the Delta Time when running compiled is much smaller than when running in the Unity Editor) and thus the character didn't move at all.
I have a system,written on PyQt4. It is mostly developed and debug under linux (ubuntu) systems, in Eric IDE, and everything works fine. Last task was to create a nested editor for a table cell. So, i did it and it also looks nice in ubuntu. I also ran it under Windows 7 x64, and the behavior was the same.
However, after making executable file with cx_Freeze in Windows 2000 (it's weird, but this environment was configured before me), the editors behavior became unexpected. After opening Editor it's first cell have 'role == Qt.EditRole', and it's almost impossible to commit any changes there without closing the whole Editor. Another issue is about "OK" button - it closes the Editor window, but doesn't commit any changes in it also, and you cannot call it again without changing the active cell (but maybe i just forgot to emit some signals here, so it's not the main bug here).
So my question - where should i look to find the reason for these problems. I'm new to qt, and maybe it is normal behavior and just my fault in code? Or the reason is in different environments (python 2.7, latest pyqt vs python 2.6 and some older pyqt). Or it is the influence of cx_Freeze... Maybe some other directions?
Sorry for long post and my English :)
Hope to get any answers soon.
I think there's a chance that Qt or PyQt on windows 2000 server is outdated or broken.
So If possible, bring cx_freeze related code to your local computer and test it out.
If it fixes the problem, you can upgrade or reinstall Qt on windows 2000 server.
