    Any advice when to use FileExists?

    in the very next second it could have the rights and vice versa

    Change 'DPI awareness' on runtime

    this looks strange, even a logical control hierarchy is missing, otherwise they would be cropped on the bottom you should try using alignments instead of fixed positions

    Change 'DPI awareness' on runtime

    or you have a common form with some extra methods 🙂

    Zip Compression library

    I'd still go with compressionmode 1 and 25sec instead of 18% better compression and almost twice the time. HDD is cheap, time isn't.

    the one I just downloaded.... must be the latest

    Zip Compression library

    I did not believe those numbers so I did it myself. source enwik9.zip http://mattmahoney.net/dc/textdata.html compression routine zf := TZipFile.Create; zf.Open('MyFile.zip', zmWrite); zf.Add('enwik9', '', zcDeflate); zf.Close; But, I don't know what TZipFile is using, own code or winapi.

    Getters & Settters??

    We are not discussing here how to free a form, I'm always using caFree which is not part of the question.

    how would you do this? Pass API params from UI into API unit

    in this case you need a wrapper unit with either making a gateway or extending the API with helpers

    bullshit

    Getters & Settters??

    I would not bother with the constructor just add a method for setup and show: procedure TTracksAddEditForm.ShowForm(const AsMode: string; AiAlbum: integer; const AsTrack: string); begin FsMode := AsMode; FiAlbum := AiAlbum; // or set the controls directly FsTrack := AsTrack; Show; end; use it: TTracksAddEditForm.Create(Self).ShowForm('Insert', blah, buh); or for showmodal function TSomeValueReturningForm.ShowForm(var AVar: string): TModalResult; begin FVar := AVar; Result := ShowModal; AVar := FVar; end; use it: lStringVar := 'Initialvalue'; case TSomeValueReturningForm.Create(Self).ShowForm(lStringVar) of mrOk: DoSomething(lStringVar); else Whatever... end; the variable var TracksAddEditForm : TTracksAddEditForm; is only needed if the forms are created with Application.CreateForm() by the dpr itself. Otherwise it should be deleted immediately.

    Difficulty with component installation

    this is a joker error message from the IDE, it can be anything, path, old binaries in the path, missing dependencies, etc... fire up a process monitor and filter for bds.exe maybe you have luck and you can see it

    SynPdf - wrong colors in PDF export

    Those bitmaps are set up diffeently, like pf32bit / pf24bit who knows what else? Could you check them with the same setup?

    Custom component on a VCL frame

    @aehimself I don't get it. I just created a new VCL Form Application plus designed two new frames, then added frame2 to frame1, without creating a custom component. What is the concept behind creating a compound component from a frame? You can also add code to the base frame and override it in the other places. I don't know any Bar Managers except Gunther, but to make a component fill up a given space is normally done with alignment.

    Custom component on a VCL frame

    just being the smart*ss, why are you mixing composite components with frames? can't you just put a frame onto an another frame?

    App is faster in IDE

    you could still put some explicit logging into your application to see where this 14 seconds delay is coming from instead of guessing

    AutoRun.Inf in USB

    I'm not sure if I can talk the english you understand. I'm telling the same. Except, there is no encryption software, it's hardware encrypted. The software only mounts the flash drive's 2nd partition with the entered password's hash. see https://www.verbatim.com/prod/usb-drives/professional-usb-drives/store-n-go-secure-pro/

    AutoRun.Inf in USB

    No, it has nothing on it, they are out of the box, the same as you are describing. Two partitions, one CD, one hardware encrypted. They exists very well nowadays too.

    AutoRun.Inf in USB

    Strange, all encrypted flash drives are autostarting its mounting application, they must be distributing themselves as CD-ROM.
