Excel Paste Crash DIAdem

[BrianCT]

We have had a few others have issues, but with data sets that have +100,000 cells of data. For the most part it seems to be my computer, I can do some testing on another computer too.

Is there a number of cells below which the issue does not occur? Or will it occur for even small numbers of cells?

[BrianCT]

i have had it happen with small (10s of cells) and large (+1000s of cells) sets of data.

Do you have any results on the testing you did on other computers?

[BrianCT]

I was not able to get either of my machines to crash during a copy paste operation during my recent work.

Hi Brian,

Thanks for the update, I'm glad to hear the issue isn't reproducing on your other computers.

I just tried reproducing the behavior (copy cells from a VIEW channel table, copy plots from REPORT) and I don't see any in behavior like what you're describing. I'm using DIAdem 2018 64-bit, but like Brad said, this isn't a known issue that was explicitly fixed in 2018.

Can you clarify which is the last command when DIAdem crashes? Is it when you copy something from DIAdem (multiple cells, a plot), or when you paste it in the external application?

It looks like there are a few workarounds at this point. Do either of these work for you for the time being?

• Use the right-click context menu to copy
• Use Brad's previous code to prevent crashing

The paste operation into an external application is what triggers the crash of DIAdem. 

We will be switching to DIAdem 2018 64-bit within a few weeks.

Hi Brian,

It sounds like your computer is the only one seeing the behavior, so we wouldn't be able to tell if the upgrade to 2018 64-bit would fix it. As Brad mentioned, this isn't a known issue so please keep us updated on your progress! We'd love to know how things are going.

Best,

Brad,

I encountered a very similar error to the one listed here in DIAdem 2019 SP1, reproducible using the same "Generate Data" script as one I sent you for another issue in REPORT. Bug #1079879

I've been able to crash DIAdem 2019 SP1 at will across a few machines by producing/loading a "large" dataset and copying 1 or more channels, then pasting external to DIAdem.

The important part is the pasting externally.  Copying data works fine, as does pasting that data to a DIAdem instance (either the current or a different instance).  A few seconds after the data is pasted in a non-DIAdem application (Notepad++, Excel) DIAdem crashes (generally without any error message whatsoever).

I attached the "Generate Data" code from before with the REPORT bit commented out and with your DataBlClpCopy statement at the end (although our users tend to use Ctrl+C and Ctrl+V from channels).  Simply run the code, and paste into another application to replicate the crash.

A few quirks i've noticed:

• It doesn't seem to matter if you add a new channel with just a few values and only try to copy that channel - having all the other data loaded makes it crash all the same.
• Copying and Pasting values from a VIEW table also crashes.  You can do a few values at a time, but the number seems to vary.

FYI, saving the produced dataset and loading it with BulkDataLoadingMode=eBulkDataLoadingOnWriteAccess (something you suggested for the other issue) appears to make no difference here.

This one is a much nastier issue because users "Copy-Paste" out of DIAdem a *lot*...Any workarounds would be appreciated!

Thanks!

Hi,

I have what appears to be the same issue with pasting data from Diadem to excel - I get crashes with both Diadem 2018 and Diadem 2020.  In my case, I am am calling many scripts in sequence to process data.  The last one of these scripts creates an excel file and writes data to it.  It almost always crashes Diadem.  If, however, I just run this script alone, Diadem does not crash....
