    Well, Alipay has about 1 billion users, "these" people pay _everywhere_, even at a grocery with their phone by scanning an Alipay QR code. They need nothing. Do you need something?

    Decorating read-only controls

    Those who want to take benefits from styling in VCL, how do you decorate your edit-boxes to make the user being able to distinguish between input ones and read-only ones? As none of the standard VCL components offer neither read-only color (except Konkopka's) nor read-only-style-color, I'm starting to think that I'm just dumb.

    Linux Support on Pro Edition

    Tell them who: a.) bought Konopka pack and it was included in the next release b.) bought mobil add-on and was included in the next release c.) bought firedac and was included in the next release Imagine those surprised faces.
  4. Works for me: procedure TTestWizard.OnAppMessage(var Msg: TMsg; var Handled: Boolean); begin if (Msg.message = WM_KEYDOWN) then begin Beep; end; end; constructor TTestWizard.Create; begin FAppEv := TApplicationEvents.Create(Application.FindComponent('EditWindow_0')); FAppEv.OnMessage := OnAppMessage;

    Decorating read-only controls

    @Dany Marmur Indeed. For example I liked my Iphone 4 much better than any Android one because they had a collection of controls and every app looked in some way the same and I knew where to tap, how to control the device.

    Decorating read-only controls

    The word you are looking for is in German "Barrierefreiheit". English, accessibility? I don't know, the German word is more expressive for me. Designers and engineers should be taught for it. Until then, I'll try my best. I found Almdev's GP* VCL components very useful, then it allows setting an alpha factor for every color used. From frames to background and fonts,etc... Thus, I can use the predefined colors and it's even works with themes together. The only thing I'm missing is an explicit read-only color-settings like in Ray Konopka's Raize components.
  7. TApplication.OnMessage seems to be assigned by default, so you are just overwriting it. I'd hook it or use a TApplicationevents component on a custom form. (Never tried) Edit: Ah I see, you are already hooking it.
  8. Or you could hook the editors onkeypress event. In both cases be careful, you have to clean up before your module gets unloaded/dumped.

    Anon methods passed as event handlers?

    @David Schwartz I made a wrapper for assigning anon methods to TField events. My experiences: Pros: a.) quick and straightforward to assign them wherever you want. Cons: a.) debugger can't evaluate sh*t inside the anon methods b.) you will never ever find again in the code jungle wtf. is happening and why The moral of the story: Moon landing was fake.

    New VCL Style from DelphiStyles.com

    You don't have to force your users to use any skins, but you can ship skins with your apps and let them select one even run time. Really? Show me two similar looking app.

    Blast from the past: BDE and Win10 W/S

    I don't get it. 7M Records or 1G data in 3 weeks is ~4 record/sec or 551byte/sec. Btw. are there really 250 "databases"?

    Barcode 128 and printing width

    With custom display DPI's too? Doesn't your thermal printer support any language?

    MMX needs new icons

    I would wait a bit until the IDE is HDPI compatible. You could also check if for-example seanau.com would cover your needs. Most of the new icons are also in SVG, and they are really easy to edit/extend whatever..

    Testing functionality "ignore topic"

    @Daniel I've noticed that the activity feed yields unread messages from the ignored threads. Just info, not a big deal.

    Testing functionality "ignore topic"

    But how would you un-ignore then? For me it's perfect now. A big thank you for it.

    Touchscreen signature

    Hi everybody, I have to make a signature input on devices with touchscreen (Normal W10 devices, VCL only). Is it something easy with a canvas/bitmap and some events and a blur filter at the end, or is it something tricky and I should buy it from TMS? thx

    Touchscreen signature

    @Der schöne Günther Nothing special, a common touchscreen like a Yoga xyz. Edit: Already done, piece of cake...

    Any advice when to use FileExists?

    I've never mention any catch and re-raise.
  21. Attila Kovacs

    Any advice when to use FileExists?

    Throw them an exception. Then they (your callers) will start checking by themselves and throwing an exception to its callers etc.. at the end you will have a solid app.
  22. Attila Kovacs

    Any advice when to use FileExists?

    completely superfluous, then for each File in MainPath do if the file can disappear between these two lines if FileExists(File) then it could also disappear between these two lines If _IsFileValidForParsing(File) then (then you decide to create the file, it could be there again) etc.. FileExists and co. are a total nonsense, then it's returning a momentary state. Put a try except around any IO and handle the last os error if apply.

    Design Packages list is not resizable

    There is a bigger problem with this form, you can't select and copy the path on the bottom. Both could be done from an expert, and would be the preferred way, before someone redesigns the whole thing. (No, it's a Label with the path <o>)

    Delphi compiler need to be opensourced

    Tangentially on topic: is it possible to exclude this particular thread from the Activity feed? (I mean me for myself, is there any setting for that)
