Thedialog.show() error - Block UI styler 1

[Obito]

hi,

I'm slowely starting to understand how all the dialog/journaling things work in nx, but I'm beeing held back from progressing because of this error I'm getting. Even in the most basic program I always get the same error.

The error is located in the sub main() & goes something like "nameofdialog.show()", but I have no clue to what I'm doing wrong. I've added the code in attachment

Greetings


(My goal is to create a dialog & implement pieces of a journal in the vb-project. But I'm kind of stuck @ the creating a dialog part.)

You need to send more of the code for us to work out what's missing.

I've just created an example, since every dialog returns the same dialog.
This code is directly copied from the blockUI styler.


The error is located in the public sub show()

A NullReference, i do know what it means, that I'm using something that's not defined, but can't seem to figur out what's wrong.

Interesting. I can't actually see anything wrong.
What version of NX are you using?
Can you attach the DLX file?

I'm using nx9, maybe it's something really obvious I'm just missing

I've attached the DLX to this message

 

[grinch33]

Executing dlg.vb as a journal runs fine for me.
The only thing I changed was to hardcode the path to the DLX file to save me having to put it into my real NX environment.
Note: I've only tested in NX8.5, I don't have time to test in NX9 right now, sorry. Can't imagine why it would fail though.
