Decompiling Delphi - 3

I came across this on delphi.about.com web site and thought it useful to add it a a reference here. continued from part two The art of reverse engineering has traditionally been the land of technical wizards, familiar with assembly language and debuggers. Several Delphi decompilers have appeared that allow anybody, even with limited technical knowledge, to reverse engineer most Delphi executable files. If you are interested in reverse engineering Delphi programs I suggest you to take a look at the following few "decompilers": IDR (Interactive Delphi Reconstructor) A decompiler of executable files (EXE) and dynamic libraries (DLL), written in Delphi and executed in Windows32 environment. Final project goal is development of the program capable to restore the most part of initial Delphi source codes from the compiled file but IDR, as well as others Delphi decompilers, cannot do it yet. Nevertheless, IDR is in a status considerably to facilitate such process. In co...

Decompiling Delphi - 2

I came across this on delphi.about.com web site and thought it useful to add it a a reference here. continued from part one For the moment, Borland does not offer any product capable of decompiling an executable (.exe) file or the "Delphi compiled unit" (.dcu) back to the original source code (.pas). Delphi compiled unit: DCU When a Delphi project is compiled or run a compiled unit (.pas) file is created. By default the compiled version of each unit is stored in a separate binary-format file with the same name as the unit file, but with the extension .DCU. For example unit1.dcu contains the code and data declared in the unit1.pas file. This means that if you have someones, for example, component compiled source all you have to do is to reverse it and get the code. Wrong. The DCU file format is undocumented (proprietary format) and may change from version to version. After the compiler: Delphi Reverse Engineering If you would like to try to decompile a Delphi e...

Demystifying DevExpress XtraReport for Silverlight - Part 3

part 4 >> Below are code snippets used in putting it all together. The first snippet is the event handler for DATASOURCE DEMANDED. Here you can change the datasouce for the report and also filter or do any other house cleaning for the report's datasource. The second snippet is the event handler for the BEFOREPRINT event for the subreprot control. This is actually the best place to bind the datasource for the subreport's report. If you use the DATASOURCE DEMANDED for the subreport - you are likely to get duplicate data printed. The last two snippets of code are just generic routines that can be used to propagate automatically all the parameter values for the master into the details and as well as assign new parameter values. Another good thing to bear in mind are these Report Class methods - GetCurrentRow - which returns an object implementing the System.Collections.IList interface the return value will be an item from the collection represented by th...
