This dates back a while, pretty sure some cross certificate (driver signing) issuer supplied this as part of an example on how to sign.a driver. I only recall because I had to remove it when we stopped cross signing everything.
-
/ph - Page hash enforcement verifies the signature on each page of the executable file as it loads into memory, this attaches the cross chain certificates
-
The installer overwrites the Environmental Path because it wants to dump everything into the OS Path with each install. Or at least that is the only thing I had to change fix for the last three updates.

And WaitForMultipleObjectsEx allows you to add alertable flags to handle Paint message or all depending on requirement.

Does the main form's OnShow event only ever fire once?
FredS replied to Gord P's topic in General Help
Which what I ended up doing in a base form. Still that single bit boolean is a quick fix if needed. -

A boolean value turned out to be better because at times there are things that should be run OnShow v. OnFirstShow.. -

Well the documentation language is always MAY 'Recreate the Window', so your mileage may vary. Think some API like SetWindowPos and MoveWindow have that, I know I ran into it while switching desktops via API.. Simpler just to add a FirstShown Property. -

Changing OS Text size was one I remember. -

I believe OnShow is also fired when a form is recreated, skin change is one of those, but the OS can trigger it as well. -
Parallel processing in delphi: handling ping results from multiple threads
FredS replied to Shrinavat's topic in General Help
You can make a hash of the IP and include that in the payload of the IcmpSendEcho2 call. Then compare those with the return payload and if they match you are done. Else store that info in an array or pass it to a callback to check in another/main thread. -
Wasn't another point to finally merge those internal and external issues.. now all external ones have become internal..

Sounds like better to me..

I'm certain the original blog post told us that months of planning went into this..

Was just going to look at that.. one 'good' thing EMBT has taught me is to generate a snapshot before attempting any installation.. DId a registry compare and it wiped out the path and the Win64 Library Path..

Thought the point was for it to be better than the last system..
