funktioner...

1: Hur gör man så att vb hämtar en viss nyckel från registret och sparar den till en fil??

2: Hur får jag alla tal att flytta till olika ställen på detta program? : http://user.tninet.se/~xkk718a/matte.zip ( med rnd funktionen.. )

3: Kan man göra så att många forms använder samma meny? Lr kan man kopiera menyn och snabbt klistra in den, och isf, hur??

2. Med Show och Hide antar jag.
3. Med PopupMenu kan du visa en meny från ett annat formulär. Men inte som meny längs titelraden.

1: Var ska jag lägga in den koden? Måste jag ha nåt speciellt för att koden ska funka?

2: Om jag har 3 tal och 3 positioner vill jag att 1 av dom 3 talen slumpvis ska hamna på en av dom 3 positionerna... osv...

[Redigerat av Alvar s den 04 jul 2000]

Jag har inte Visual Basic installerat för tillfället.

Kan du förtydliga dina frågor?

1. Lägg koden i en modul och kör funktionerna.

Förstår inte vad du menar med skriva ut en nyckel dock.

2. Vad för sorts positioner?

exempel

5 + 5 = 10
7 + 7 = 14
1 + 7 = 8

istället kunde det bli tex:

1 + 7 = 8
7 + 7 = 14
5 + 5 = 10

1 + 7 = är en label och svaret är en text där man skriver in svaret, alltså måste båda flyttas till samma ställe på nåt sätt...
