I wrote some program in C++ Builder 6 (don't ask me why). I do some actions with on-form components after formResize event occurs. But it occurs right after I close my program, and looks like all components on form where deleted, so I've got exception and everything crashes. There is my code: void __fastcall TForm3::FormResize(TObject *...
Hello, I am working in the Borland C++Builder IDE, using VCL controls. I am trying to get a TStringGrid component to scroll down to a row and highlight that row, based on user input in a different form. I have the highlight portion done, but I can't figure out how to scroll the grid down to the correct row. Anyone here know? ...

I'm a newbie at using the STL Algorithms and am currently stuck on a syntax error. My overall goal of this is to filter the source list like you would using Linq in c#. There may be other ways to do this in C++, but I need to understand how to use algorithms. My user-defined function object to use as my function adapter is struct is...
I have a batch file that tries to compile a static library using Borland C++ Builder 6.0 It is called from Borland make (makefile created with bpr2mak) which is called from a .bat file (used to compile the whole project with Visual Studio and some Borland C++ Builder legacy projects), which is called from a bash shell script running ins...
I'm using C++Builder, and am trying to slowly migrate code to using C++ standard library in preference to the Delphi VCL. The VCL has a streaming architecture based around the TStream class, and I'm switching to using std::stream instead. However, in the short term, I still need a way of 'mixing' use of the two stream types. I can do ...
Hi, is the order of overloaded methods in the vtable always the same across win32 compilers? Problem: I have "interfaces" (pure virtual classes with no data members). They can be used via pointer from different compilers (the client gets the pointer by calling a standard c dll factory method). This works fine across different compiler ...

The serialization example below is from the boost mailing list which is pretty much the same as what I would like to do. However, I have changed the archive so that it will serialize to XML. The compile does not fail if I serialize to binary, but it fails when serializing to xml. The compile fails in basic_xml_oarchive.hpp in the followi...
Hello I had recently asked a question about how to do the following: Write a function that sums all the integers in a matrix of integers using the following header: const int SIZE = 4; double sumMatrix (const double m [] [SIZE] , int rowSize, int columnSize) ; Write a test program that reads a 4-by-4 matrix and displays the sum of a...
I have a TTimer in my application that fires every 2 seconds and calls my event handler, HandleTimerEvent(). The HandleTimerEvent() function modifies shared resources and can take 10's of seconds to execute before returning. Furthermore, I call Sleep() in the event handler to relinquish the processor at times. I'm not sure how C++ build...
