2.5) btnInsert: ( 15 ) Write cоde tо insert а new recоrd into tblEmployee. You must creаte the EmpCode by using the first letters of the nаme and surname respectively, in capitals. Add to this an integer value. The integer value is determined as follows: if it is the first record with these initials it is 1 and then the number is incremented each time the same initials are used. E.g. The EmpCode value for the new record will be KM2 as a record with the value KM1 as a primary key already exists for Karel Malan in the table. If the insert was successful, you should see the new record in the dbGrid component. Use the following data to test your button: EmpCode FirstName LastName Department EmploymentDate Smoker Gender Karel Malherbe 1 99/08/27 Yes M See the Addendum page for a screenshot of the changed output in the dbGrid. Skryf kode om n nuwe rekord by te voeg tot tblEmployee. Jy moet die EmpCode waarde skep deur die eerste letters van die naam en van onderskeidelik, in hoofletters, te gebruik. Voeg hierby 'n heelgetalwaarde. Die heelgetalwaarde word soos volg bepaal: as dit die eerste rekord met hierdie voorletters is, is dit 1 en dan word die getal verhoog met een elke keer as dieselfde voorletters gebruik word. Bv. Die EmpCode waarde vir die nuwe rekord sal KM2 wees aangesien n waarde van KM1 reeds bestaan as n primere sleutel (vir Karel Malan) in die tabel. As die insert aksie suksesvol was, behoort jy die nuwe rekord te sien in die dbGrid. Gebruik die data hierbo om jou knoppie te toets. Die Addendum bladsy bevat n skermgreep van die veranderde afvoer in die dbGrid.
1.1) btnRegister: ( 28 ) Cоmplete the cоde fоr the button аs follows: A globаl vаriable named sContestantNum has been created for you to use in the rest of the program. Ensure that the age entered into sedAge is valid for the category selected in the radiogroup named rgpCategory. In order to participate in the Primary School category the entrant has to be between 7 and 13 years old. To participate in the High School category the participant has to be between 13 and 18 years of age. If the entered age is not valid, a message to that effect must be displayed. The contestant number is created by using the first letter of the name, add to this the first three letters of the surname followed by a dash (-), the correct prefix for the category (first three letters if category is Primary and first two letters if category is High School: use "copy" to obtain the prefixes), followed by the art form and an even number randomly generated between 20 and 300. See the Addendum page for a screenshot of the output of this question.

Verseker dat die ouderdom wat in sedAge ingelees is, geldig is vir die kategorie wat in die radiogroup genaamd rgpCategory geselekteer is. Vir die deelnemer om te kan deelneem aan die Laerskool kategorie moet die ouderdom tussen 7 en 13 jaar wees. Om te kan deelneem aan die Hoërskool afdeling moet die deelnemer tussen 14 en 18 jaar oud wees. Indien die ingevoerde ouderdom ongeldig is, moet 'n boodskap vertoon word om hierdie feit duidelik te maak aan die gebruiker. Die deelnemernommer word geskep deur die eerste letter van die naam te neem, voeg hierby die eerste drie letters van die van, gevolg deur ʼn koppelteken (-), die korrekte voorvoegsel vir die kategorie (die eerste drie letters word gebruik as die kategorie "Primary School" is en die eerste twee letters word gebruik as die kategorie "High School" is: gebruik "copy" om die voorvoegsels te kry), gevolg deur die kunsvorm en ʼn ewekansig gegenereerde ewe nommer tussen 20 en 300.
