Do these false positives also occur with other compilers? Yes, this is has been a common problem in the past for AutoIt as addressed in this forum post “Are my AutoIt EXEs really infected?”. In most cases including AutoIt it stems from poor heuristic practices. Since AutoIt uses the free and open UPX compressor, it … Read more
I was slightly bored, and I wanted to play with my new Delphi XE, so I’ve made a component for you. It should work in older Delphi’s just fine. You can download it here: BitEditSample.zip How does it work? It inherits from customcontrol, so you can focus the component. It contains an array of labels … Read more
You can do something similar (not exactly) with standard components; TDBCtrlGrid, TSpeedButton,… alt text http://img8.imageshack.us/img8/9585/imagen29ox3.png
The original author of the PNGImage component (the basis of the Delphi native component) had a forum where he, and others, posted code snippets on how to do things using the PNGImage component. Before the forum was taken down I grabbed a copy of all of the code snippets and placed them on the CodeGear … Read more
You are missing the Chromium Embedded Framework (CEF) core libraries. It is enough to copy the content of the ..\dcef\bin\Win32 folder (from your downloaded package) into your project’s output directory (or into some of the known folders location reachable from your project’s executable).
See Forward Declarations and Mutually Dependent Classes documentation. type (* start type section – one unified section “to rule them all” *) TAsyncPopulator = class; (* forward declaration, it basically serves just to fix SizeOf(TAsyncPopulator) so compiler would be able to draft dependent types’ in-memory layout. Down the CPU level `class` and `pointer` is the … Read more
Firstly, an apology. In my answer to your last question, CreateCellControl should have called inherited to create the cell. I’ve amended my answer. As for this question, I’ve uploaded my blog posting on FireMonkey Cells – http://monkeystyler.com/blog/entry/firemonkey-grid-basics-custom-cells-and-columns – it covers the stuff from the previous answer, and also covers creating custom cell controls. You’ll need … Read more
The closest equivilent to your XCode approach is to use an “interposer” class in Delphi. Basically, you do not change the code that the IDE creates for the standard TToolBar usage. You instead declare a new class that derives from the standard TToolBar component but is also named TToolBar and you make it visible to … Read more
The difference has to do with where you’re allowed to refer to the things that AConsts has in its interface section. In the first AUnit, you could use Const4 to declare a fixed-size array in that interface section. You couldn’t do that in the second AUnit because Const4 isn’t in scope. It can have an … Read more
You can indeed use Assert for this. Write a procedure that matches the signature dictated by the TAssertErrorProc type, and then do whatever you want there. To preserve the expected behavior, you should probably call the original handler after you’re finished. procedure MichaelAssertProc(const Message, Filename: string; LineNumber: Integer; ErrorAddr: Pointer); begin LogMessage(…); SysUtils.AssertErrorHandler(Message, Filename, LineNumber, … Read more
