How to generate auto id in c++?

it fixes the issue I have a class,in which I want the id ,to be generated automaticly; , You must use of a static member to counting the objects :
code :
class Id
{
    public:
        Id()
        {
            id = unique_id++;
        }

    int get_id()
    {
        return id;
    }

    private:
        int id;
        static int unique_id;
}
static int Id::unique_id = 0;
Id id1;        // id1.get_id() will return 1
Id id2;        // id2.get_id() will return 2
Id id3;        // id3.get_id() will return 3

should help you out You could use custom t4 templates to generate them. If you then need to edit them manually, i guess you could make them partial but then you'd need to make the other half of the partial class manually.

this one helps. Thank you to @CheGueVerra , he pointed me in the right direction. I just changed the directory location to be in ProgramFiles and it was able to compile.
code :
  <Fragment>
    <Directory Id="TARGETDIR" Name="SourceDir">
      <Directory Id="ProgramFilesFolder">
        <Directory Id="INSTALLFOLDER" Name="Manager" />
      </Directory>
    </Directory>
  </Fragment>
<Directory Id='TARGETDIR' Name='SourceDir'>
    <Directory Id="IISMain" Name='inetpub'>
        <Directory Id="WWWMain" Name='wwwroot' 
           ComponentGuidGenerationSeed='{Put-your-own-generated-guid-here}'>
            <Directory Id='INSTALLFOLDER' Name='Manager'>
            </Directory>
        </Directory>
    </Directory>
</Directory>
Auto-generate and auto-update timestamps in Eloquent

hope this fix your issue You need to use Eloquent Entity to create your object.
Keep in mind Eloquent will search for database name depending on the class name. The class have to be in single form but eloquent will search for the plural version of it.
code :
<?php 

namespace App;

use Illuminate\Database\Eloquent\Model;

class Category extends Model 
{
     protected $table = 'categories'; // not neccessary in this case

}
$category = new CategoryEntity();
$category->category = 'your category';
$category->sort_order = 'your sort order';
$category->save();
$category = CategoryEntity::find($your_category_id);
$category->category = 'your category';
$category->sort_order = 'your sort order';
$category->update();

I hope this helps . Turns out yes it is possible, and the way to do that is to write the models-x.json files out for all models with a script, and then start the server after the script has finished!
https://docs.strongloop.com/display/public/LB/Database+discovery+API
code :
const loopback = require('loopback');
const fs = require('fs');
const path = require('path');
const async = require('async');

var ds = loopback.createDataSource('postgresql', {
  'host': 'localhost',
  'port': 5432,
  'database': 'foo',
  'username': 'bar',
  'password': 'baz'
});


ds.discoverModelDefinitions(function (err, models) {

  async.each(models, function (def, cb) {

    ds.discoverSchema(def.name, null, function (err, schema) {
      if (err) {
        console.error(err.stack || err);
        cb(err);
      }
      else {
        fs.writeFile(path.resolve(__dirname, 'server/models', def.name + '.json'),
          JSON.stringify(schema), {}, cb);
      }
    });

  }, function (err) {
    if (err) {
      console.log(err.stack || err);
      process.exit(1);
    }
    else {
      console.log(' => Successfully wrote model data.');
      process.exit(0);
    }

  });
});
