programm crashs when instancing new object

[Marcus Schaefer]

Hello,

I have a queer problem in my project (Visual Basic Express 2005):

When I create a new Instance of one of my classes

dim data as new CData(fname) <-- crash !
Dim frm as new CMDIChild()
frm.Data = Data

my program crashs without any further error message. Debugging results in no
additional information. To extend the problem I can fix this bug, if i swap
the two above lines

Dim frm as new CMDIChild()
dim data as new CData(fname)
frm.Data = Data

BUT this fix doesn't work on all computers I'm testing my project.
=========

The class CData doesn't access the CMDIChild class.

Do you have any ideas?? I fear it is an error in the Visual Basic Express
compiler.

Thank you for any ideas / hints,

Marcus

are you sure you are instantiating a class of yours?

Hi Tom,

I changed the class names, to clearify the purpose of the classes. But as
you pointed out the correct names may be important:

The real name of "CData" is "CSpectrum"
and of "CMDIChild" is "frm_Document".

Therefore an accidental mix-up with CLRAdmin.CData is out of question.
But thank you for your idea.
