Stackoverflow vs Google+ for Delphi? Stackoverflow is usually my go-to place for answers on development issues. However it seems that a lot of Delphi related Q&A is now being done in this group as opposed to SO. So is the Delphi community now preferring this forum over others? I've even found myself seeking programming answers here and often what seems to be an "ignored" SO question ends up on here as last cry for help. I like Stack Overflow for its historical artifacts and powerful search capabilities as opposed to the G+ forums which are almost impossible to find things beyond the last few pages. This is just my observations, interested to hear other thoughts.

Maybe someone can take a look at my current problem on Stackoverflow with Spring4D? http://stackoverflow.com/q/35922238/5648977?sgp=2

Why is the GPUCanvas disabled by default in FMX on WIndows? In a test-application i noticed huge improvements to resizing of elements in terms of being more fluid. http://docwiki.embarcadero.com/Libraries/Seattle/en/FMX.Types.GlobalUseGPUCanvas http://docwiki.embarcadero.com/Libraries/Seattle/en/FMX.Types.GlobalUseGPUCanvas

I know I can write MyRecordVar := Default(TMyRecordType) because I asked a question in the Embarcadero Forum and Remy Lebeau kindly answered it. Unfortunately I was stupid enough and didn't copied it to my local notebook, so again I can't find anything about it in the documentation, and the forum database seem to be gone. I'd like to know what it does, how it works. If my memory serves me well it is not a regular routine, so I don't even know where to begin searching as I can't find search terms that would make google results meaningful. TIA.

That code smells (System.Variants.pas): function TInvokeableVariantType.FixupIdent(const AText: string): string; begin   Result := AnsiUppercase(AText); end; procedure TInvokeableVariantType.DispInvoke(Dest: PVarData; [Ref] const Source: TVarData;   CallDesc: PCallDesc; Params: Pointer); var   LIdent: string; begin   LIdent := FixupIdent(TEncoding.UTF8.GetString(BIdent, 0, I)); Why is AnsiUppercase instead of Uppercase called?

This is probably a classic problem, but I can't seem to Google a solution. I have a string in the debugger that is a very large XML file. I want to get the entire value of the string out of the debugger, but I can't only seem to get a truncated value. Is there any way to coerce the debugger to cough up the entire string? I should probably know this, but I don't.

I have a task (at work) to spike a replacement to the current OLE Excel with some native Excel component (that doesn't required Excel to be installed).

Hi, can someone point me in the direction of figuring out how to get at the data when I select a row in TStringGrid? TStringGrid is bound to datasource. So when clicking on an individual row I want to display the data from the columns in that row in labels, etc below the TStringGrid.

What's the normal response time for Embarcadero customer support? I've submitted a case last Sunday but haven't had any response yet. Also, I can't access the case status because it requires a login which apparently is not accessible with my EDN account credentials.

Hi, I want to open string A Big No Navigator WHEN USING the ShellExecute(Handle,'Open',PChar(LURL),nil,nil,SW_NORMAL);  the url is cut into the browser , because the PCHAR is limited. It has something to replace the PCHAR on the command line ?

Hi, client's code to set it's app as a default handler (eg, opening) no longer works. Reading brings me to the reason that the current registry edits to set an app as a default no longer works on Win8 and above (that Hash value on UserChoice is really a killer) and tried deleting the HKCU\..\FileExts\..\UserChoice key,  making my app the only one in HKCU\..\FileExts\..\OpenWithProgids and lot's of registry edits that I could find in the net but I somehow can't get it to work. Any help is appreciated. Thanks.

I have been looking at Rudy Velthuis BigIntegers unit ( http://rvelthuis.de/programs/bigintegers.html ) with an eye to using it in DWScript. The contact email appears invalid, and there does not seem to be a repository.... In case you're reading this Rudy, I have a couple bug fixes to report, and some question about moving it to a repository :)

Since about 10.30 this morning I have been getting a Security Warning when opening Delphi 10 Seattle and then at intervals while I am us it. The security warning is the insecure content dialog "Do you want to view only web page content that was delivered securely?" then a More Info button (which shows nothing) and Yes/No buttons This usually shows when a main page is called using https and then parts of the page are called using http. Interesting that the Delphi banner shows then disappears.

does anybody know which software connects to these domains and if that's a bad sign? kaspersky.commander1.com hal9000.redintelligence.net online-metrix.net choices.truste.com choices-or.truste.com For me they look either like advertising and/or other ad related urls or maybe a virus?

See, the developers of the Delphi compiler, nothing is impossible. Originally shared by Maciej Izak Hi, I'm pleased to finally announce the additional record operators: Initialize, Finalize.

Let's improve Delphi's Wikipedia page! Hi everyone. The Delphi Wikipedia page is not very good. It's not written in good English style, is messy, is kindof negative, is out of date, lists few details for each version, does not give a good overview of the language / features / use, etc. Can we improve it? I started yesterday by rewriting the introduction, making it flow better, mentioning up-to-date language features, and the inter-op with C++Builder. Just now I also uploaded a screenshot of Seattle (it last had a screenshot of XE2.) Things that (in my opinion) need attention: * Distinguishing Features - well, it doesn't really describe any of the distinguishing features. (It has VCL and COM, interface delegation, Windows message handers.) Where is FMX? Where are managed types in a native language (e.g. strings, interfaces)? Where is the cross-platform-ness? All are missing, and I think some of them including those that are already there need examples, or at least better...

I'm playing with TSharingContract on Windows 10. Sending a bitmap works as expected, but I could not find a way to share a non-standard file like a PDF document or ZIP archive. The windows explorer has a "Share" button, which works well with those files, but how to do that in Delphi code? The documentation skips this case. Perhaps Paweł Głowacki can give me some hints. TIA Achim
