'System.StackOverflowException'

[ThePentiumGuy]

hi,

 

when i run my program (something i made in d3d),

i get this error

 

An unhandled exception of type 'System.StackOverflowException' occurred in Unknown Module.

 

i have no idea how to fix this error lol, sry for being so vague but i cant exactly Pinpoint wehre the error originated.. (it says unknown module)

 

 

if anyone has encountered this problem, can you please explain where it may originate ( & if possible, how to fix it)

Are you in an endless loop somewhere or dividing some int ?

[ThePentiumGuy]

i think endless loop might be it :-)

[ThePentiumGuy]

wow..

i tracked the problem down

the program seemed to be continuously repeating this line:

Public alex As New clsSprite() 'this is the first variable in the declarations, so i dont see why it would go through a loop

 

the statement that (for some reason) caused it to loop:

(in clsSprite) i said:

Inherits D3D_Engine.D3DGraphicsClass 'the class in which i declared that variable

 

really odd..

i ahve no idea why vb would do that

[Robby]

Were you instantiating the class within a loop?

You can view the Call Stack (ctrl-alt-c) when your program breaks. It will show you all the code that's been called. I would guess you'll see two lines of code (or maybe a few more) being called over and over. One of them should provide clues. If you can't get it, let us see some more of your code...

hey,

thanks for the replies..

ctrl alt c doesnt work (maybe that's a vs.net 2003 thing?) o_O

 

but here's my code

 

Public Class D3DGraphicsClass
   Public alex As New clsSprite()
End Class

Public Class clsSprite
   Inherits D3DGraphicsClass
End Class

'aand finally form1's declarations: 
   Dim Game As New D3DGraphicsClass()

 

-(note: this code is the shortened version of my otehr code... -but: i actually tried using this same exact code and it still gives the error)

When your application breaks on the stack overflow error, try going to Debug>Windows>Call Stack to see the same thing

[PlausiblyDamp]

Public Class D3DGraphicsClass
   Public alex As New clsSprite()
End Class

Public Class clsSprite
   Inherits D3DGraphicsClass
End Class

'aand finally form1's declarations: 
   Dim Game As New D3DGraphicsClass(

 

clsSprite inherits D3DGraphicsClass - every time you create a clsSprite it calls the D3DGraphicsClass new method - and in it's new method you are creating a new sprite etc.

Is there a reason why you are doing it this way?

[ThePentiumGuy]

ohh! actually there's no reason why im doing it that way.. lol i didnt realize that it would create the variables again

 

where would i instantiate clsSprite though?

 

edit: never mind, i figured it out :-)

 

thanks for ur help guys
