[ D3 | D4 | D5 ]
QMemory is a new memory manager. You can use it as a replacement of the default system memory manager. To do this simply add QMemory unit in your project (as the first unit listed in the project file). Don't forget to call the QMemCompact function when your application is idle. This subroutine decommits the unused memory blocks and compacts an internal table for speeding up the memory manager. All allocated memory blocks are 32 byte aligned. The minimum size of the block is 32 bytes. As it is necessary to store some information with each block a dword is attached to the front of each block at -4 the aligned address. Thus, memory requests for up to 28 bytes allocate a 32 byte block, requests for 29 to 60 bytes allocate a 64 byte block, etc. This idea was adopted from HPMM project of Robert Lee (rhlee@optimalcode.com). The memory is committed and decommitted in 64K blocks. The maximum amount of the memory is specified when QMemInstall function is called (from the initialization section of the unit). You can't change this value later. This memory manager works at the same speed as a default memory manager with the blocks up to 4096 bytes and much more faster with the larger blocks. If some parts of your program implemented as DLLs you have to use ShareQmm instead of QMemory unit. }

[ bkhash11.zip ] [ 9,187 bytes ] [ Freeware ] [ No Source ]
[ D2 | D3 | D4 | D5 ]
A fast associative array targeted specifically at create and looking up associations between strings and 32-bit untyped fields (usually pointers to records or classes).

  • Compromises in favor of speed: string - 32-bit pointer only
  • Has protected interface for custom memory allocation.
  • Supports function pointer and method pointer iteration
  • Plug-in different hash function
Examples:
 hash.add('abc', myobject); TMyObject(hash['abc']).Whatever; if not hash.Find('abc', myobject) then .. TObject(hash.remove('abc')).Free; // removes and frees without temp hash.Iterate(nil, Iterate_FreeObjects);

[ dd-resfile.zip ] [ 31,891 bytes ] [ Freeware ] [ With Source ]
[ D4 | D5 | D6 | D7 | D2 ]

This unit contains classes that encapsulate Windows 32 bit binary resource files and the resources contained in them. The main functionality is provided by two classes:

  1. TPJResourceFile # encapsulates the contents of a whole resource file and provides methods and properties for reading, finding, editing, adding and deleting resources. Resource files can be read from and written to files or streams.
  2. TPJResourceEntry # encapsulates a single resource within the file and provides properties to access its header record and its raw data. The class also provided methods to check the identity of the resource. The resource's raw data is made available as a TStream and so is easily read and written using familiar TStream methods.

Note that the classes have no knowledge of resource data formats and see the resource data simply as a raw sequence of bytes. It is for the user of the class to interpret the data correctly.

In addition to the two main classes, some useful helper functions and constants are also provided.

The download includes a UserGuide that provides detailed description of the classes, along example code for the key methods.

[ delphi-ics.zip ] [ 173,315 bytes ] [ Freeware ] [ With Source ]
[ D2 | D3 | D4 | D5 ]
Delphi-ics is a wrapper to CyberSource's Win DLL for C/PERL. It will allow you to communicate with the CyberSource Commerce servers(provided you have a merchant id) thru the Cybersource windows DLL that was written for C and Perl interfacing. Just include the wrapper file(ics_wrapper.pas) to any project via the "uses" clause and your good to go! I created a simple test app so you can see how its used. Everything is fully commented. One note. CyberSources new DLL(3.2.1.0) only works on NT! v3.2.0.0 works on Win95/98 with no problem, although I dont know why you would run a webserver on 95/98! My wrapper works with both. Developed with, and only tested in Delphi 5. Should work fine with D2, D3, or D4.
Hope this helps someone!

TExplorerD4 is a freeware component that embed a Microsoft Explorer 4.0 or earlier ActiveX control.
It can browse HTML pages, run ActiveX controls, run Java Script or VB Script and so on. And, this is the meaning of the component, it can inform your application when the user click on a HREF correctly formatted command.
This is the porting in Delphi 4.0 of the TExplorerCommand component, written for Delphi 3.0x and give you the power of the new WebBrowser component that come with Delphi 5.0, and more else.
