WebUI framework: Technical preview. Part 1.

You have a couple of "bundles". Do you mean the three library bundle? I'm curious as a potential customer. -
Delphi and "Use only memory safe languages"
JonRobertson replied to Die Holländer's topic in General Help
Different languages have different rules and syntax. Is that really an issue? I see the "issue" as developers using the incorrect syntax for the language they are currently using. If I toured Italy, I imagine my trip would be more enjoyable if I spoke Italian. Which I don't. -
Delphi and "Use only memory safe languages"
JonRobertson replied to Die Holländer's topic in General Help
Should that matter? I started learning Pascal 35 years ago and C the following year. Not once have I written c := (a < b) ? a : b; or if (a == b) { doSomething(); } while writing Pascal code. -

Works for me as well in 11.3. -
D2007: Initialise byte array in const record

What do you get when you try const sig1: FileSig = (Offset: 10; arrSig: [$00,$01,$02]; ) in D2007? -

I have a lot of respect for your knowledge and experience, seeing some of the work you have done. However, I think that is a fairly bold assumption. Since 1996, I have preferred Delphi over other development tools/languages/frameworks. I do not enjoy doing GUI work. But I believe a lot of what "operates the world" is line of business apps, whether they be for commerce, government, health care, or hundreds of other industries. Computers can't read our minds (thankfully). And voice recognition is not that reliable. I see proof of that every time my mother-in-law sends a text. -
TIniFile will work on any file that conforms to the INI file format, and it seems the RemoteHost.cfg that you have uses the INI file format. But many, if not most, .cfg files will use a different format that isn't compatible with TIniFile.

Always pay attention to compiler warnings and hints. Most of the time, the compiler is being helpful. Had you resolved the compiler warning, you would have solved the issue without needing assistance. Asking for assistance isn't a bad thing, that's the beauty of forums like these. But solving issues without assistance is even better, for me anyway. My opinion is that I am not "finished" with code unless it compiles with zero compiler warnings and hints. Sometimes I even add a statement just so the compiler will be "happy". I believe that W1036 should be an error rather than a warning, as using an uninitialized variable is almost always a bug in the code. I only say almost because I've learned there are exceptions to every rule. Warnings can be changed to errors at the project level. I have W1036 set to an error in my projects. This is done in project options. See this post if needed: state of an uninitialized variable try/finally should be a habit when any resource is created or allocated, or a state that should be undone, such as setting Screen.Cursor or calling methods such as DisableControls/EnableControls and BeginUpdate/EndUpdate. Once you've developed the habit, you won't even think about doing it. It'll just be natural. And it'll avoid a lot of potential headache. I neglected to mention it earlier because it was end of day on a Friday and I was ready to leave the office. Oops!

You are likely getting an AV because RHini is not initialized to nil. As a local variable, it has a random value until initialized. You should have a compiler warning: [dcc32 Warning] W1036 Variable 'RHini' might not have been initialized Change your top line to: var RHini: TIniFile := nil; or perhaps var RHini: TIniFile := TIniFile.Create(AppDir +'\RemoteHost.cfg');

Have you tried using TIniFile and the various Write* methods to write the needed values to the .cfg file? If there are numerous writes, you could use TMemIniFile. System.IniFiles.TIniFile
-
I completely agree. Unfortunately, people who write the "corporate check" don't always agree.
-
Not at all. I'm sharing what seems to be an opposing opinion. I suppose to clarify any miscommunication, since your ideals about what "I prefer" were opposite of what I actually prefer.

Delphi and "Use only memory safe languages"
JonRobertson replied to Die Holländer's topic in General Help
Yes, although more of a helper. Removes the with identifier do [and begin/end statements if present] and copies "identifier." to the clipboard so you can easily paste it where needed. It does not automatically determine which fields need the "identifier." added. Very simple example: Before: with Form1 do begin Left := 200; Top := 100; end; Invoke MMX Convert with: After: Left := 200; Top := 100; And "Form1." is in the clipboard to be manually pasted where needed. -

Hopefully not with Shift-Alt-W (MMX Convert with statement) is a good friend of mine when "migrating" legacy Delphi code. -
Good delphi learning sites for new team member

If you are familiar with other programming languages, I ran across a Cross Reference site that could be useful. It currently cross references 14 languages. Cross Reference Coding -
That is just nonsense in my opinion. Of course the details of a trial are relevant to the trial. Saying otherwise is almost as inconceivable as saying the details of the license agreement are irrelevant to my use of a software product or developer tool. What about the page that quite clearly says at the top Download AppGini Free Trial Or perhaps on the Frequently Asked Questions page, for someone like me that would want to know.

I prefer projects have documentation. But a lack of documentation does not keep me from investigating. Reading the code is the best way to learn what they do. It takes time to learn new things. I find learning to be extremely valuable. If that was directed at me personally, it should not have been. You have no idea how much money I have spent on software or developer's tools since I started learning to program 43 years ago. I don't understand why a person or company that creates a product they believe would be useful to others wouldn't spent a few minutes to inform potential customers the details, including limitations, of a trial version or offer.
-
Nope, but I clicked the link out of curiosity. I just love commercial products that offer a trial but give no details about the trial period, expiration, or trial limitations. However, the price sounds very reasonable... if it works

Strange bug with string literals in RAD Studio 12

For me as well. Although I planned to wait until the end of April just to see the feedback on 12.1 before I started. -

GPT and other AI services aren't capable of thinking. They only "know" what has been trained or other resources to use as a reference (ie code online that a human originally wrote). If I wrote some assembly code that I posted online somewhere and GPT used my code as a reference point, any code that GPT generated would blow big time. -
State of an uninitialised variables..
JonRobertson replied to Ian Branch's topic in Tips / Blogs / Tutorials / Videos
If you want a "default" set of options to apply to each project, you can use Option Sets. Here are a couple of links: from-default-project-options-to-rad-studio-option-sets Option Sets Overview -
State of an uninitialised variables..

Project Options, Building, Delphi Compiler, Hints and Warnings: Expand "Output warnings" and scroll down to "Variable might not have been initialized". Select the drop down and set it to "Error": Note there are *dozens* of warnings that you can change to errors. -

JonRobertson replied to Ian Branch's topic in Tips / Blogs / Tutorials / Videos
Agreed. I still think the code demonstrated in the report (and the example posted by Der schöne Günther) is unexpected behavior. objectAsString := 'Hello World'; objectAsString := TJson.Format(objectAsJson); WriteLn(objectAsString); // << It is "Hello World{}" (not including linebreaks) I would not expect 150 to be written to the console for this code: function GetAmount: Integer; begin Result := 50; end; begin var i: Integer := 100; i := GetAmount; writeln(i); end. The compiler even hints that the initial value is never used. [dcc32 Hint] H2077 Value assigned to 'i' never used -
When I started using Delphi 11.x, I was frustrated by frequent IDE lockups and exceptions. After talking to Embarcadero, I selectively uninstalled each component library and expert to try and identify if third-party code was causing those issues. The issues that I was experiencing disappeared once I uninstalled the Parnassus debugger and bookmarks experts. Since then, Delphi 11.3 has been extremely stable for me. Jon
