datagrid - are shown as a white rectangle with a red cross

[Thomas]

hi,

- I use the datagrid without a real database, only to display my memory data
and it works fine.
- If I install the application at an other computer the datagrid doesn't
work and disappear, a white blank area with a red cross are shown instead.
- it never happened, if I compile the application at the other computer,
although the computers use the same .net framework version.

I figured out, it happened if I call a special function. This function
hasn't nothing to do with data in the datagrid.

Anybody know or assume what happened?

Thanks Thomas

Thomas,

I thought I had seen this before in the newsgroups.
In the language VBNewsgroup Ken Tucker wrote "It is a bug"

I found as well this threads wherein are some workarounds.

Maybe they help you.

Hi Cor,

thanks for the hint, there are some entries but I didn't find a real
solution or workaround for me.

An other one assume there is something wrong with the memory. I assume it
also, because the error occure if I call a certain function. In this funtion
I create many new objects and leave new created objects on the heap, maybe
some carbage collection destroy the datagrid.

Unfortunately it not happend at my computers, so I can't debug this issue!

Cheers Thomas

It can be however very unlikely, than the program should use everytime exact
the same piece of memory, what has in my opinion a very low change.

Or did it only happens once?
