Solution 1

Possible reason:

- PrintForm1 could be null
- PrintForm1.PrinterSettings could be null
- PrintForm1.PrinterSettings.DefaultPageSettings could be null.

Please check for null before you proceed.

Update 1:

Null Check in VB:

VB

If PrintForm1 IsNot Nothing Then

'YOUR CODE

End If

Nish's Guess:

PrintForm1 is null.

Try,

VB

PrintForm1 = New PrintForm1
PrintForm1.PrinterSettings.DefaultPageSettings.Landscape = True
PrintForm1.Print()

Mark it as answer if it is helpful

waqi19 21-Feb-11 21:27pm

coz my teacher didnt teach us this and he just put the whole code for us to copy.

Nish Nishant 21-Feb-11 21:28pm

You need to instantiate PrintForm1.

Voted 5, good answer.

Most likely null candidate is PrintForm1.
