Combine String and array of WChar

[rpetges]

Hi,

I have an issue combining a String type with an array of wchar.

The WIN32_FIND_DATAW structure has a property called cFilename of type array[MAX_PATH] of WCHAR and in my application I have a variable L_Path of type String.

The cFilename property contains a Non-English Unicode filename and I need to build the complete path :

L_Path :=  IncludeTrailingPathDelimiter(L_Path) + L_WIN32_FIND_DATAW.cFileName

This results in an "Implicit string type conversion with potential data loss from "WideString" to "AnsiString" .. I can confirm that the result is wrong.

How can I combine both without data loss ?

Many thanks,
Romain

Have you tried using a UTF8String instead?

It will still maintain a Byte wide string but will contain code points >= 128 if there.

Code: Pascal  [Select][+][-]

1. L_Path :=  IncludeTrailingPathDelimiter(L_Path) + L_WIN32_FIND_DATAW.cFileName

Hi!

I'm not a codepage expert, but:

Code: Pascal  [Select][+][-]

1. L_Path :=  IncludeTrailingPathDelimiter(L_Path) + UTF8Encode(UnicodeString(L_WIN32_FIND_DATAW.cFileName));

I tried L_Path :=  IncludeTrailingPathDelimiter(L_Path) + UTF8String(L_WIN32_FIND_DATAW.cFileName) and it works fine 

Thank you !

That depends on how you use L_Path.  Windows doesn't support UTF-8 encoded paths, only ANSI and UTF-16 encoded paths.  So, unless L_Path is also declared as UTF8String, and IncludeTrailingPathDelimiter() doesn't modify the contents of L_Path if it has non-ASCII characters in it, and L_Path is converted back to UTF-16 when passed to Win32 APIs, then there is still quite a potential for data loss in the above code snippet.
