Re: Handle Inheritance in Windows Emilio Garavaglia22-Mar-11 22:34 Emilio Garavaglia 22-Mar-11 22:34  When you create an object (like a mutex) you can specify a "name". (see CreateMutex[^]). In the child process you can retrieve another handle to that same object with OpenMutex[^], or whatever similar and coherent with the type of object) by giving it that name (that is supposed to be unique at least between all your entangled processes). Note that the returned value may be different, due to the fact the the handle value is an "index of a table of indexes" that is different in the various processes. The documentation talks improperly of inheritance of handles. What are inherited are the objects the handle refers to. 2 bugs found. > recompile ... 65534 bugs found. ShowDropDown(...) error _Flaviu21-Mar-11 0:30 _Flaviu 21-Mar-11 0:30  I think I'm front with a weird problem at combo box control : If drop down list of combo box is down , and I delete all strings from combo box and call ShowDropDown(FALSE); I have assert error on strcore at 519 line . In fact , it's mistake to call ShowDropDown(FALSE); when combo box is empty ? Re: ShowDropDown(...) error Code-o-mat21-Mar-11 1:48 Code-o-mat 21-Mar-11 1:48  Don't know what might cause that error but try "undropping" the list and then delete the strings? Or there's a particular reason why you try to delete first and then remove the list? > The problem with computers is that they do what you tell them to do and not what you want them to do. < > //TODO: Implement signature here< Re: ShowDropDown(...) error _Flaviu21-Mar-11 3:00 _Flaviu 21-Mar-11 3:00  Yes , you are right , I thing that's the way to solve this problem ... weird behaviour .

The blog entry here shows you how to do it for ATL, but not stl: http://blogs.msdn.com/b/andypennell/archive/2004/02/06/69004.aspx[^] Re: Automatically Stepping over stl code in Visual Studio Stefan_Lang21-Mar-11 7:32 Stefan_Lang 21-Mar-11 7:32  Interesting article, thanks for the link. After reading it, I would say you can apply the same principle to STL by using the registry entry “std\:\:.*=nostepinto” instead of “ATL\:\:.*=nostepinto”. I haven't tried though. In any case, before trying this I'd create a restore point or whatever else you usually do to undo an unlucky change. It is an undocumented feature after all, and even if it weren't, manually editing the registry isn't for the weak of heart.

CPallini20-Mar-11 23:03 CPallini 20-Mar-11 23:03  What kind of Unicode text file are you dealing with (e.g. UTF-8, etc..)? What do you mean with 'character' (e.g. 'Unicode character' or 'single byte'?)?

Albert Holguin21-Mar-11 3:31 Albert Holguin 21-Mar-11 3:31  Hope you do know that unicode is two bytes and ascii is one byte... Re: How can read a unicode text file as character by character? Emilio Garavaglia22-Mar-11 22:43 Emilio Garavaglia 22-Mar-11 22:43  UNICODE is actually a set of code-points whose cardinality requires 21 bits. When encoded in sequence of 1 bye is called UTF-8 and when encoded as sequence of two bytes is called UTF-16. In UTF-8 coding may vary from 1 to 4 bytes (and remains identical for code-points between 0 and 127, aka ASCII) In UTF-16 coding may be 2 or 4 bytes (and is TWO for the most of Latin, Cyrillic and Greek characters, as many simplified Chinese). UNICODE==2bytes is a misconception that originated at the time Windows included Unicode APIS using 16bits since -at that time- Unicode specs where not so wide. Actually, reading 2bytes does not necessarily means "read a character". 2 bugs found. > recompile ... 65534 bugs found. Re: How can read a unicode text file as character by character? Albert Holguin23-Mar-11 4:07 Albert Holguin 23-Mar-11 4:07  unfortunately, i think it depends on what standard of C/C++ and what OS. I'm pretty sure windows defines unicode as 16bits... from their website: "Unicode: A fixed-width, 16-bit worldwide character encoding that was developed and is maintained and promoted by the Unicode Consortium, a nonprofit computer industry organization." http://msdn.microsoft.com/en-us/library/cc194793.aspx[^] Re: How can read a unicode text file as character by character? Emilio Garavaglia24-Mar-11 8:37 Emilio Garavaglia 24-Mar-11 8:37  I'm sorry for you and for Microsoft, but the one and only entitled to say what Unicode was, is and will be is www.unicode.org[^] The page you linked is a very shame for Microsoft. A technical document like that cannot be written without specifying in the page itself a data when it was written (hey ... they speak about their new amazing Windows NT 3.5 ...) and for this sole fault should disqualify M$ of whatever authority in the field. 2 bugs found. > recompile ... 65534 bugs found.

Re: How can read a unicode text file as character by character?

Re: How can read a unicode text file as character by character? Albert Holguin23-Mar-11 4:21 Albert Holguin 23-Mar-11 4:21  Here's another reference to Microsoft: http://msdn.microsoft.com/en-us/library/2dax2h36.aspx[^] Re: How can read a unicode text file as character by character? Emilio Garavaglia24-Mar-11 9:57 Emilio Garavaglia 24-Mar-11 9:57  Nope. 1) Unicode is not a Microsoft product. What UNICODE is is defined by www.unicode.org[^] 2) Microsoft use to encode UNICODE into 16-bits units. That is a technique well defined by the UNICODE standard itself, known as UTF-16. Essentially, every code not in the range 0xD800-0xDFFF and lower than 0xFFFF is code as itself. Every other greater that 0xFFFF is broken in two 10-bits chunks, or-ed with 0xD800 and 0xDC00 respectively. The range 0xD800 - 0xDFFF is called "UNICODE surropgate" and does not contain valid codepoints. So you can have single unicode characters requiring two wchar_t in sequence to be represented and sequences of two wchar_t representing a single character, with code greater than 0xFFFF (typical for CJK - Chinese, Japanese, Corean characters). 2 bugs found. > recompile ... 65534 bugs found. Re: How can read a unicode text file as character by character? Albert Holguin24-Mar-11 10:02 Albert Holguin 24-Mar-11 10:02  i certainly believe your point about unicode consortium being the authority... no argument there!
