TWebUpdate and UAC control

VCL TMS VCL UI Pack
1

Hello


Unit WebUpdate contains

{$IFDEF USEUAC}
{$R WUPDATE.RES}
{$ENDIF}

{$IFNDEF USEUAC}
{$R WUPDATENO_UAC.RES}
{$ENDIF}

I have customer that has very strict rules regarding elevating rights. So each update of TMS components I have to remember to "turn off" USEUAC directive.
Is there a chance that you could rebuild this part to allow that on the project level, through some directive we can choose if we would like to use UAC or not.

TIA

You could add the define USEUAC at project level

What if I'd like to use updater with NO_UAC?
USEUAC is defined in this unit, so apparently there is no chance to turn it off at project level. :-(

Remove the line

{$DEFINE USEUAC}
from WEBUPDATE.PAS and use it when needed at project level

This exactly what I meant - everytime there is new version of component set, I have to remember to remove (or comment out) this line in this unit :-)
Could you consider something more permanent? :-)

TIA

That is the solution for the situation how it is NOW.

I'm not sure how it can be addressed in another way. We will need to reflect on that.

Maybe invert the default?

Do not predefine USEUAC directive in WebUpdate.Pas and leave it to define at project level.

It is clear that any chance we consider needs to preserve backwards compatibility. We cannot afford to cause problems / unexpected behavior changes for the many other users who have come to expect the current behavior as default.

Filename has changed to Wupdate.pas

10

Not sure where you get this info from, but I cannot find any evidence that in more than a decade this component exists, that the unit was ever named anything else than wupdate.pas

11

Just took filename from your post on the 20th. When I couldn't find WebUpdate.pas figured the unit name had been changed

Was a typo indeed in post of 20 Feb, sorry for the confusion.

Backwards compatible way to allow to disable UAC:

or - where you define USEUAC

this will retain the USEUAC as default, but allow you to disable it by a project define (assuming you compile the .PAS file to .DCU in all projects).

Controling the usage of UAC

I do not understand why something more is needed beyond what is already standard available with the existing USEUAC define.

Hi Bruno.

I've posted a bit of explanation about why it can be useful here:

What we have now works fine, the suggestion by Keld just simplifies things for users a bit, to be able to disable this conditional (e.g. with a project level define) without having copy/edit the entire WUpdate.pas source code.

Understood.
It is even somewhat more complex as $UNDEF isn't supported in old Delphi versions.
But it makes sense to control this at project level and leave the TMS VCL UI Pack source code untouched.
We will apply this improvement.
