Spaces are used for separating Arguments. In your case **C:\Program** becomes argument. If your file path contains spaces then add Double quotation marks. Then cmd will recognize it as single argument. 

Spaces are horrible in filenames or directory names.

The correct syntax for this is to include every directory name that includes spaces, in double quotes

cmd /c C:\&quot;Program Files&quot;\&quot;Microsoft Visual Studio 9.0&quot;\Common7\IDE\devenv.com  mysolution.sln /build &quot;release|win32&quot;

I&#39;m using Entity Framework 5 with Visual Studio with Entity Framework Power Tools Beta 2 to reverse engineer moderately sized databases (~100 tables).

Unfortunately, the **navigation properties do not have meaningful names**. For example, if there are two tables:

&lt;!-- language: lang-sql --&gt;

    CREATE TABLE Contacts (
        ContactID INT IDENTITY (1, 1) NOT NULL,
        ...
        CONSTRAINT PK_Contacts PRIMARY KEY CLUSTERED (ContactID ASC)
    }

    CREATE TABLE Projects (
        ProjectID INT IDENTITY (1, 1) NOT NULL,
        TechnicalContactID INT NOT NULL,
        SalesContactID INT NOT NULL,
        ...
        CONSTRAINT PK_Projects PRIMARY KEY CLUSTERED (ProjectID ASC),
        CONSTRAINT FK_Projects_TechnicalContact FOREIGN KEY (TechnicalContactID)
            REFERENCES Contacts (ContactID),
        CONSTRAINT FK_Projects_SalesContact FOREIGN KEY (SalesContactID)
            REFERENCES Contacts (ContactID),
        ...
    }

This will generate classes like this:

&lt;!-- language: c# --&gt;
    
    public class Contact
    {
         public Contact()
         {
              this.Projects = new List&lt;Project&gt;();
              this.Projects1 = new List&lt;Project&gt;();
         }
         public int ContactID { get; set; }
         // ...
         public virtual ICollection&lt;Project&gt; Projects { get; set; }
         public virtual ICollection&lt;Project&gt; Projects1 { get; set; }
    }

    public class Project
    {
         public Project()
         {

         }
         public int ProjectID { get; set; }
         public int TechnicalContactID { get; set; }
         public int SalesContactID { get; set; }
         // ...
         public virtual Contact Contact { get; set; }
         public virtual Contact Contact1 { get; set; }
    }

I see several variants which would all be better than this:

- Use the **name of the foreign key**: For example, everything after the last underscore (`FK_Projects_TechnicalContact` --&gt; `TechnicalContact`). Though this probably would be the solution with the most control, this may be more difficult to integrate with the existing templates.
- Use the **property name** corresponding to the foreign key column: Strip off the suffix `ID` (`TechnicalContactID` --&gt; `TechnicalContact`)
- Use the **concatenation of property name and the existing solution**: Example `TechnicalContactIDProjects` (collection) and `TechnicalContactIDContact`

Luckily, [it is possible to modify the templates by including them in the project][1]. 

The modifications would have to be made to `Entity.tt` and `Mapping.tt`. I find it difficult due to the lack of intellisense and debug possibilities to make those changes.

*Concatenating property names* (third in above list) is probably the easiest solution to implement.

**How to change the creation of navigational properties in `Entity.tt` and `Mapping.tt` to achieve the following result**:

&lt;!-- language: c# --&gt;
    
    public class Contact
    {
         public Contact()
         {
              this.TechnicalContactIDProjects = new List&lt;Project&gt;();
              this.SalesContactIDProjects = new List&lt;Project&gt;();
         }
         public int ContactID { get; set; }
         // ...
         public virtual ICollection&lt;Project&gt; TechnicalContactIDProjects { get; set; }
         public virtual ICollection&lt;Project&gt; SalesContactIDProjects { get; set; }
    }

    public class Project
    {
         public Project()
         {

         }
         public int ProjectID { get; set; }
         public int TechnicalContactID { get; set; }
         public int SalesContactID { get; set; }
         // ...
         public virtual Contact TechnicalContactIDContact { get; set; }
         public virtual Contact SalesContactIDContact { get; set; }
    }

    cmd /c &quot;C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.com&quot; mysolution.sln /build &quot;release|win32&quot;

Unfortunately this does not work, because I get the error:
&gt; &#39;C:\Program&#39; is not recognized as an internal or external command,
operable program or batch file.

As I understand, I need quoting for the spaces and quotes for the |, but I am only allowed to use the quotes once.

Any ideas how to quote this command line call correctly?

I need to delete all .jpg and .txt files (for example) in dir1 and dir2. 

What I tried was:

    @echo off
    FOR %%p IN (C:\testFolder D:\testFolder) DO FOR %%t IN (*.jpg *.txt) DO del /s %%p\%%t

In some directories it worked; in others it didn&#39;t. 

For example, this didn&#39;t do anything:

    @echo off
    FOR %%p IN (C:\Users\vexe\Pictures\sample) DO FOR %%t IN (*.jpg) DO del /s %%p\%%t

What I&#39;m I missing in the second snippet? Why didn&#39;t it work? 

Delete all files of specific type (extension) recursively down a directory using a batch file

I was trying to write a VPN dialer/disconnector using a batch file, but I got stuck. After some investigation I found that the presence of `%` in the password is not playing well.

Here is the code

    @echo OFF
    SET SWITCHPARSE1=%1
    SET SWITCHPARSE2=%2
    REM echo %SWITCHPARSE1%
    SHIFT
    SHIFT
    IF &quot;SWITCHPARSE1&quot; == &quot;&quot; goto Usage
    IF &quot;SWITCHPARSE1&quot; == &quot;/?&quot; goto Usage
    IF &quot;SWITCHPARSE2&quot; == &quot;&quot; goto Usage
    IF &quot;SWITCHPARSE2&quot; == &quot;/?&quot; goto Usage


    IF &quot;%SWITCHPARSE1%&quot; == &quot;sl&quot; (
        IF &quot;%SWITCHPARSE2%&quot; == &quot;conn&quot; (
            echo &quot;inside sl conn&quot;
            rasdial sl employee1 K%%Pxev3=)g:{#Swc9
            goto end
        ) ELSE IF &quot;%SWITCHPARSE2%&quot; == &quot;disconn&quot; (
            rasdial sl /disconnect
            goto end
        ) ELSE (
            goto Usage
        )
    ) ELSE IF &quot;%SWITCHPARSE1%&quot; == &quot;off&quot; (
            IF &quot;%SWITCHPARSE2%&quot; == &quot;conn&quot; (
            rasdial Office employee1 office123
            goto end
        ) ELSE IF &quot;%SWITCHPARSE2%&quot; == &quot;disconn&quot; (
            rasdial Office /disconnect
            goto end
        ) ELSE (
            goto Usage
        )
    ) ELSE (
        goto Usage
    )

    :Usage
    echo &quot;Usage is vpnconn.bat /[sl|off] /[conn|disconn]&quot;

    :end

In the above script I am trying to escape `%` using `%` (i.e. `%%`, reference from [here][1]), but the bat script gives **g:{#Swc9 was unexpected at this time.**.

To root cause further, I tried to double `%%` (escape `%`) in a different batch file, and it worked:

    @echo OFF
    rasdial sl employee1 K%%Pxev3=)g:{#Swc9

Why does the same script when integrated to work with different connections not work?

Escape percent in bat file

Is it possible in windows cmd line to check all of the network addresses (with ping or similar) to see which ones are taken/ have active devices:

ie. something that does something like the following:

    for i = 0 to 255
        ping 192.168.1.i //Print this
    end

This is psuedo code obviously. I am wondering if it is possible to do something like this in windows cmd. It would be great if you didn&#39;t need a batch file, but i understand if this is impossible. 

PS. Also please mention if there is a program to do this, but it would be nice to do it in cmd.

I know Unix has the following command which can execute multiple commands in a single line, how can I do this in DOS?

    command1 ; command2 ; command3 ...

How to execute multiple commands in a single line

I made this code
    
    dir /B /S %RepToRead% &gt; %FileName%

    for /F &quot;tokens=*&quot; %%a in (&#39;type %FileName%&#39;) do (
    	set z=%%a
    	echo %z%
        echo %%a
    )

`echo %%a` is working fine but `echo %z%` returns &quot;echo disabled&quot;.

I need to set a %z% because I want to split the variable like `%z:~7%`

Any ideas?
