Sounds like bullshit to me. No random crashes that we didn't cause ourselves that I can remember, and I've used every Delphi version there is, on most of the Windows versions there has been.

There is one unmentioned drawback to VMs. The more you have, the more you need to keep updated and patched. That is the price you pay for flexibility.

The only thing that is slow in my VMs is 3D gfx, but since I don't rely on those - it is not a problem.

MS submitted changes to the Linux kernel in June 2020 that would allow running Hyper-V hosting on Linux. Not sure if this is present in any current Linux release yet.

3D GPU performance is a mixed bag, imo - but why would you test that in a VM? You'd remote debug that from the VM on a physical machine. The CPU is virtualized, so I guess the only time you'd get into trouble is if you try to run something like a VM with 8 cores on a 4 core machine or use more memory than is physically present. I would expect Hyper-V to simply cut down to the max avail if exceeded.

Well, Delphi 32-bit stops at 2Gb. If you need more memory, I suggest a 64-bit app.

@Tommi Prami It would have been awesome if we could do helpers for generics. We can't.

I used paid VMWare workstation for years. About a year ago, I switched to Hyper-V and never regretted doing so.

Then there is this: https://www.microsoft.com/en-us/microsoft-365/blog/2021/04/28/beyond-calibri-finding-microsofts-next-default-font/

It may be that the Outlook 2003 OLE server lacks some of the interfaces that your OLE client implementation requires. 2003 is pretty ancient...

It seems that the @Inserted_Values temp table does not use TIMESTAMP. declare @Inserted_Values table ( WX_5Min_Key int NOT NULL, [DateTime] DateTime NOT NULL );

Have you looked into which joins that fail? Is it possible to see any differences in the stored data / parameters that can cause joins that fail? Is the type strictly identical - ie both parameters and tables columns are of the TIMESTAMP type?

Have you applied the most recent patches?

It is useful to post the actual errors for others to be able to think about the cause.

What target? Windows, iOS, Android, Linux? 32 or 64 bit? In the IDE or outside?

Which database do you use? Attached the reformatted SQL for readability. Personally I would never use a timestamp for a join, but that is probably just me. test.sql

The Delphi generics lack constraints support for enumerations and sets.

Perhaps @David Millington has a tip?

Hmm, yeah, that's a conundrum. A better pattern would be that your included subscription follows the cycle of the major version - i.e. 10.4.x.

I am on active update subscription. Can you even have 10.4.2 without one, considering that if you just bought 10.4.1 or 10.4.2 you would be within the one year subscription?

@Marco Cantu - Has the RAD Studio Web Installer been updated with the patches, or do you have to patch after installation?

In that case, it is silly that the patches are not in order, and that two of them have the same date. IMO, the description should have contained the patch number.

I assume order of installation is not important.

Make that three patches.
