Closed 3 years ago . can you recommend an open source Delphi crypto library that works with Delphi 2006, Delphi 2009 & Delphi 2010 Algorithms need : DES, MD5, SHA-1 回答1: Here is a short list of the libraries I have used both pre and post D2009: TPLockbox (I use an unofficial updated version. Although there is a recent official(?)

问题 I have a JSON Object, let's name it jObject that looks like this: { "id": 0, "data": "[{DAT_INCL: \"08/03/2012 10:07:08\", NUM_ORDE: 1, NUM_ATND: 1, NUM_ACAO: 2, NUM_RESU: 3}, {DAT_INCL: \"08/03/2012 10:07:09\", NUM_ORDE: 2, NUM_ATND: 1, NUM_ACAO: 4, NUM_RESU: 5}, {DAT_INCL: \"08/03/2012 10:07:09\", NUM_ORDE: 3, NUM_ATND: 1, NUM_ACAO: 8, NUM_RESU: NULL}]" } As you can see, it contains two pairs, one of which is an array with three objects in this case (the amount of objects is dynamic) with

问题 TDirectory.GetFiles has a parameter called SearchPattern. Embarcadero's documentation says The mask used when matching file names (for example, "*.exe" matches all the executable files). However, I want to pass multiple file types. I get those types from a FilterComboBox.Mask . So, it is a string that looks like '*.txt;*.rtf;*.doc' . I have tried to pass that string directly to GetFiles and it doesn't work. Do I have to parse it, break it into pieces and feed every individual piece to

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . Can anyone recommend a cryptographically-secure pseudo random number generator library for Delphi (Win32)? Can be free or commercial, but will ideally be an active project. I'd like it to include source code. 回答1: You can use Windows CryptoAPI: uses Wcrypt2; function GenerateRandom(Len: Cardinal): TBytes; var

问题 I need to get the full path from a PID. I've checked this question C++ Windows - How to get process path from its PID and I wrote the following code: function GetFullPathFromPID(PID: DWORD): string; var hProcess: THandle; ModName : Array[0..MAX_PATH + 1] of Char; begin Result:=''; hProcess := OpenProcess(PROCESS_ALL_ACCESS,False, PID); try if hProcess <> 0 then if GetModuleFileName(hProcess, ModName, Sizeof(ModName))<>0 then Result:=ModName else ShowMessage(SysErrorMessage(GetLastError));

问题 I created a new c++ DLL project in VS2010 that exposes 1 function #include "stdafx.h" #define DllImport extern "C" __declspec( dllimport ) #define DllExport extern "C" __declspec( dllexport ) DllExport int DoMath( int a, int b) { return a + b ; } I then created a C++ application with VS2010 to test this DLL. The test application build in VS2010 could call the c++ DLL and get the expected result. #include "stdafx.h" #include <windows.h> typedef int (*DoMath)(int, int) ; int _tmain(int argc,

问题 When using Delphi 2007 along with Indy 9, what are the latest OpenSSL libraries that can be loaded and where are they available? 回答1: You need the following two DLLs: libeay32.dll ssleay32.dll You can download the source from the open-source organization OpenSSL.org, but then you have to compile the DLLs yourself. Indy maintains a site of compiled binaries for each version of Indy and OpenSSL (see indy.fulgan.com/SSL and indy.fulgan.com/SSL/Archive -- thanks to TLama for the links). Older

问题 Another synchronization question...I hope you guys don't get annoyed ;) Assume the following scenario: one central data structure (very large, so I don't really want to make it immutable and copy it around whenever a change occurs. I even don't want to keep multiple copies in memory), multiple reader threads that access that data structure read-only and one writer thread which keeps the data structure up to date in the background. I currently synchronize all accesses to the data structure,

问题 I know this question has been asked before, but I have yet to see a short, clear answer, so I'm hoping they won't remove this question and I will now get a clear answer: I am currently working in C# 5.0; .NET 4.5; VS 2012. I am mostly a Delphi guy although I've done lots with C#. In Delphi I have written hundreds of class factories that use the following sort of design (MUCH SIMPLIFIED HERE): unit uFactory; interface type TClassofMyClass = class of TMyClass; TFactoryDict = TDictionary<TMyEnum

问题 In Delphi sane people use a class to define objects. In Turbo Pascal for Windows we used object and today you can still use object to create an object. The difference is that a object lives on the stack and a class lives on the heap. And of course the object is depreciated. Putting all that aside: is there a benefit to be had, speed wise by using object instead of class? I know that object is broken in Delphi 2009, but I've got a special use case 1) where speed matters and I'm trying to find
