Form Level COC syntax

 Useful COC syntax

1. Form level

2. Form Datasource level

3. Form DataField level

4. Form Control level

Form level CoC:

When extending a form, use formStr(<FormName>)

 Get Buffers:  

FormRun               formRun             =  this as  FormRun;
FormDataSource  dataSource_ds    =  formRun.datasource(FormDatasourceStr(FormName,DatasourceName));
TableName             tableName         =  dataSource_ds.Cursor();
FormControl          formControl      =  formRun.design().ControlName(FormControlStr(FormName,ControlName));

 Example:

[ExtensionOf(formStr(SalesTable))]
final class KSSalesTableFrm_Extension
{
    public int active()
    {
FormRun              formRun                  = this as  FormRun;

        //get any datasource from the base form
FormDataSource salesLine_ds            = formRun.datasource(FormDatasourceStr(SalesTable,SalesLine));  
SalesLine              salesLine                  = salesLine_ds.Cursor();

//get any formcontrol from the base form
FormControl      itemName= formRun.design().ControlName(FormControlStr(SalesTable, itemName));

//business Logic

 return next active();
      }
}

2. Form Datasource level CoC:

When extending a form Datasource, use formDataSourceStr(<FormName>, <DataSourceName>)

Example:

[ExtensionOf(formDatasourceStr(SalesTable, SalesLine))]

final class KSSalesTableFrm_SalesLineDS_Extension
{
    public void executeQuery()
    {
         next executeQuery();

        FormDataSource                  formDS                    = this;

        FormComboBoxControl      comboBoxControl;   

        //get form datasource       
        SalesLine             salesLineLocal  = this.cursor();               

//get any other datasource from the base form

        FormDataSource inventDim_ds  = formDS.formRun().dataSource(formDataSourceStr(SalesTable, InventDim));

        InventDim            inventDim      = inventDim_ds.cursor();

//get any formcontrol from the base form

        comboBoxControl     = formDS.formRun().design().controlName(formControlStr(SalesTable, SalesTable_SalesTypeGrid));

        //business logic

    }

}

3.  Form Datafield level CoC:

When extending a form Datasource Field, use formDataFieldStr(<FormName>, <DataSourceName>, <DataFieldName>)

Example:

[ExtensionOf(formDataFieldStr(SalesTable, SalesLine, BarCode))]

final class KSSalesTableFrm_SalesLineDS_BarCodeDF_Extension

{

    public void modified()

    {

         next modified();

         FormDataObject                    barCode_do = any2Object(this) as FormDataObject;

         FormComboBoxControl       comboBoxControl;        

         //get form datasource

        FormDataSource                 salesLine_ds   = barCode_do.datasource();
        SalesLine                              salesLine         = salesLine_ds.cursor();

//get any other datasource from the base form

        InventDim    inventDim     = salesLine_ds.formRun().dataSource(formDataSourceStr(SalesTable, InventDim)).cursor();

//get any formcontrol from the base form

 comboBoxControl   = salesLine_ds.formRun().design().controlName(formControlStr(SalesTable, SalesTable_SalesTypeGrid));

        //business logic

      }

}

4.  Form DataControl level CoC:

When extending a form DataControl Field, use formDataControlStr(<FormName>, <ControlName>)

Example:

[ExtensionOf(formControlStr(SalesTable, PrintMgmt))]

final class KSSalesTableFrm_PrintMgmtCtl_Extension

{

    public void clicked()

    {

        FormControl                       buttonControl         = any2Object(this) as FormControl;

        FormRun                             formRun                 = buttonControl.formRun();

       

        InventDim                           inventDim

        FormComboBoxControl   formComboBoxControl;

//get any datasource from the base form

        inventDim     = formRun.dataSource(formDataSourceStr(SalesTable, InventDim)).cursor();

//get any formcontrol from the base form

 formComboBoxControl   = formRun.design().controlName(formControlStr(SalesTable, SalesTable_SalesTypeGrid));

        next clicked();

        //business logic

      }

}
