dbc_BeforeDBGetProp Event
Occurs before the DBGetProp( ) function runs. There are two versions of the syntax.
PROCEDURE dbc_BeforeDBGetProp(cName, cType, cProperty)
PROCEDURE dbc_BeforeDBGetProp
LPARAMETERS cName, cType, cProperty
Parameters
cName
Specifies the value of the first parameter in the DBGetProp( ) function, the name of the database, field, named connection, table, or view for which DBGETPROP( ) returns information.cType
Specifies the value of the second parameter in the DBGetProp( ) function, the object type of the item named in cName.cProperty
Specifies the value of the third parameter in the DBGetProp( ) function, the property for which DBGETPROP( ) returns information.
Remarks
You can use the dbc_BeforeDBGetProp event to track attempted access to the database before DBGetProp( ) runs.
Return .F. from this procedure to prevent the property value from being returned to DBGetProp(). This will cause the DBGetProp() function to return NULL.
Example
* Reports to the screen Event name, where it is called from and ;
* the parameter passed.
PROCEDURE dbc_BeforeDBGetProp ;
(cName,;
cType,;
cProperty)
? '>> ' + PROGRAM()
?? ' in ' + SUBSTR(SYS(16),RAT('\',SYS(16))+1)
? ' Current DBC: ' + SUBSTR(DBC(),RAT('\',DBC())+1)
? ' cName = ' + TRANSFORM(cName) + ' - ' + TYPE('cName')
? ' cType = ' + TRANSFORM(cType) + ' - ' + TYPE('cType')
? ' cProperty = ' + TRANSFORM(cProperty) + ' - ' + TYPE('cProperty')+' /end/ '
