}

Overstående er min kode, jeg får følgende 2 fejl: Error    1   
The name 'main' does not exist in the current context    C:\Users\mdm\Documents\Visual Studio 2008\Projects\Project1\Project1\CodeFile1.cs    179    25    Label
- Dette er fejl 1.

Error    2    The name 'txtDisplayOutput' does not exist in the current context    C:\Users\mdm\Documents\Visual Studio 2008\Projects\Project1\Project1\CodeFile1.cs    195    13    Label
Dette er fejl 2.

Angående fejl 2 kunne jeg forstille mig at txtDisplayOutput skulle hedde btn istedet for txt.

Ps. koden er fra Beginning C.Sharp 2008 - er det bare mig eller er den fyldt med fejl.

jeg bruger visual studio 2008.

I din main metode, hvor du instasierer frmMain kalder du referencen mail - tror det er derfor main i næste linie ikke eksisterer.

Mht 2'eren så tror jeg det er txtResult du skal bruge, du vil vel ikke udskrive hele resultatet som knappens tekst?
