Use the command &lt;code&gt;dir&lt;/code&gt; to list all the directories and files in a directory; &lt;code&gt;ls&lt;/code&gt; is a unix command.

I already tried to follow the example of other answers from here and I did not succeed! 

I created a reactive form (ie, dynamic) and I want to disable some fields at any given time. My form code:

    this.form = this._fb.group({
      name: [&#39;&#39;, Validators.required],
      options: this._fb.array([])
    });
    
    const control = &lt;FormArray&gt;this.form.controls[&#39;options&#39;];
    control.push(this._fb.group({
      value: [&#39;&#39;]
    }));

my html:

    &lt;div class=&#39;row&#39; formArrayName=&quot;options&quot;&gt;
      &lt;div *ngFor=&quot;let opt of form.controls.options.controls; let i=index&quot;&gt;
        &lt;div [formGroupName]=&quot;i&quot;&gt;
          &lt;select formArrayName=&quot;value&quot;&gt;
            &lt;option&gt;&lt;/option&gt;
            &lt;option&gt;{{ opt.controls.value }}&lt;/option&gt;
          &lt;/select&gt;
        &lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;

I reduced the code to facilitate. I want to disable the field of type select. I tried to do the following:

    form = new FormGroup({
      first: new FormControl({value: &#39;&#39;, disabled: true}, Validators.required),
    });

not working! Does anyone have a suggestion?

After updating domain password, accessing git-repo is no longer possible. VS Code and Source Tree as well as Visual Studio are returning the following error message on pull, push, fetch etc..

    fatal: Authentication failed

Normally a credentials pop-up should appear however this is not happening. Also the common recommendation... 

    git config --global credential.helper wincred

...is not working.

So I&#39;m using Docker Toolbox because I don&#39;t have Hyper-V on my machine since it&#39;s not Windows 10 pro. Everything seems to work fine, but when I try to go on my browser `0.0.0.0:80` it always returns me: This site can’t be reached

But when I run the command: `docker container ps` I get the following: ` 0.0.0.0:80-&gt;80/tcp` meaning that this address should work. I searched across stackoverflow and github issues. Now I&#39;m stuck. 

Am I missing something? 

Thanks,
Mark

EDIT:

Using `docker-machine ip default` returns me `192.168.99.100`. I run that on port 80. I still get the same result except that the address becomes the container id: `https://fd677edg12`

I run that command on cmd to find my ipv4: `cmd /k ipconfig /all`. Put the result with the port and it returns the same thing: `https://fd677edg12`

Android Emulator is incompatible with Hyper-V, but Docker relies on Hyper-V. 
Is there any solution that I can run them simultaneously？

I am trying to get started with Docker on Windows. My machine has 4GB of RAM and a 1.9GHz - 2.5GHz Intel i5 processor, running Windows 10 Pro x64. I know these aren&#39;t powerful specs, but I would have thought I should be able to run Docker?

However, having downloaded Docker, I get the error message:

&gt; Not Enough memory to start docker

I have seen various forum posts and github issues about this and followed all the advice I can see, such as modifying the settings in Docker, I tried these:

[![enter image description here][1]][1]

They also mentioned changing the settings of the Hyper-V VM however, this seems to be deleted and recreated with the Docker specified settings on every attempted launch. I tried 2048MB, 1792MB, 1536MB, 1280MB and 1024MB of RAM, all of which failed. 

What else can I do? Surely I can run docker in some form on my machine? NB: I have closed all non-essential background apps. There doesn&#39;t seem to be many other suggestions for what seems to be a fairly common issue, where the given solutions don&#39;t work?

After installing anaconda3 in windows, I can run python commands from the anaconda prompt, but not from the windows command prompt.
I would like to make a desktop shortcut to activate my environment and run spyder from it. Previously, I would do this with a `.bat` file, but now that I cannot run python commands from `cmd.exe` this doesn&#39;t work.

Is there an alternative way of running batch files for the anaconda prompt?
I know that I could just modify my `PATH` to get `cmd.exe` to run python commands, but I&#39;d like to avoid this if possible.

I&#39;m writing a batch program for copying all files *newer than the destination* from &quot;C:\Users\ADMIN\Desktop&quot; to &quot;D:\Backup&quot;. 

This code is works:

    xcopy &quot;C:\Users\ADMIN\Desktop\*.*&quot; &quot;D:\Backup\&quot; /K /D /H

However, it asks for each existing destination file: `Overwrite file [Yes / No / All]?`

I want to **overwrite** all existing destination files **without** user intervention.

How can I solve this?
