===How to serialize collections===
 
−
Serializing collections, including custom or standard collections (like TList) requires writing custom converters. For example, lets consider the folowing collection declaration:
 
−
 
 
−
<pre class="brush:delphi">
 
−
type
 
−
  TItem = class
 
−
  public
 
−
    X: Integer;
 
−
    Y: Integer;
 
−
  end;
 
−
 
 
−
  TItems = class(TObjectList<TItem>);
 
−
</pre>
 
−
 
 
−
To be able to serialize it, we need to declare a converter class, and '''associate''' this class with our collection using Converter attribute:
 
−
 
 
−
<pre class="brush:delphi">
 
−
type 
 
−
  TItemsConverter = class(TConverter)
 
−
  public
 
−
    function  GetReadMode: TReadMode; override;
 
−
    procedure Write(S: TSerializer; const V); override;
 
−
    procedure Read(D: TDeserializer; var V); override;
 
−
  end;
 
−
 
 
−
  [Converter(TItemsConverter)]
 
−
  TItems = class(TObjectList<TItem>);
 
−
</pre>
 
−
 
 
−
The converter can be implemented like this:
 
−
 
 
−
<pre class="brush:delphi">
 
−
</pre>

LMD ShellPack

Using Paste/Copy commands at runtime

Copy: 

if assigned(LMDShellList1.selected) then
  LMDShellDoContextMenuVerb( LMDShellList1, (LMDShellList1.Selected as TLMDShellListItem).ShellItem, 'copy');

Paste: 

LMDShellDoContextMenuVerb( LMDShellList2, LMDShellFolder2.ActiveFolder,'paste');

LMD RichPack

Which MS RichEdit DLL Version can I expect on a specific operating system?

Please check list of different RichEdit versions.

Searching for specific attributes

Q: I was trying out the LMD RTF wrapper (using BCB 6) and wanted to know what would be the best way to search for words or characters with a specific attribute. A:

  • Use FindTextEx
  • Check SelAttributes
    if attrs not ok then FindTextEx again.

LMD WebPack

[Linker Error] Unresolved external "InternetCloseHandle" referenced from

Simply add wininet.lib to your project (file can be found in \lib directory of your C++ Builder / BDS / CRS installation). In recent IDEs you can also add

#pragma link "wininet.lib"
in your code.
