11 | // FILE: StdString.h | |
12 | // AUTHOR: Joe O'Leary (with outside help noted in comments) | |
13 | // | |
14 | // If you find any bugs in this code, please let me know: | |
15 | // | |
16 | // jmoleary@earthlink.net | |
17 | // http://www.joeo.net/stdstring.htm (a bit outdated) | |
18 | // | |
19 | // The latest version of this code should always be available at the | |
20 | // following link: | |
21 | // | |
22 | // http://www.joeo.net/code/StdString.zip (Dec 6, 2003) | |
23 | // | |
24 | // | |
25 | // REMARKS: | |
26 | // This header file declares the CStdStr template. This template derives | |
27 | // the Standard C++ Library basic_string<> template and add to it the | |
28 | // the following conveniences: | |
29 | // - The full MFC CString set of functions (including implicit cast) | |
30 | // - writing to/reading from COM IStream interfaces | |
31 | // - Functional objects for use in STL algorithms | |
32 | // | |
33 | // From this template, we intstantiate two classes: CStdStringA and | |
34 | // CStdStringW. The name "CStdString" is just a #define of one of these, | |
35 | // based upone the UNICODE macro setting | |
36 | // | |
37 | // This header also declares our own version of the MFC/ATL UNICODE-MBCS | |
38 | // conversion macros. Our version looks exactly like the Microsoft's to | |
39 | // facilitate portability. | |
40 | // | |
41 | // NOTE: | |
42 | // If you you use this in an MFC or ATL build, you should include either | |
43 | // afx.h or atlbase.h first, as appropriate. | |
44 | // | |
45 | // PEOPLE WHO HAVE CONTRIBUTED TO THIS CLASS: | |
46 | // | |
47 | // Several people have helped me iron out problems and othewise improve | |
48 | // this class. OK, this is a long list but in my own defense, this code | |
49 | // has undergone two major rewrites. Many of the improvements became | |
50 | // necessary after I rewrote the code as a template. Others helped me | |
51 | // improve the CString facade. | |

104 | // REVISION HISTORY | |
105 | // | |
106 | // 2005-JAN-10 - Thanks to Don Beusee for pointing out the danger in mapping | |
107 | // length-checked formatting functions to non-length-checked | |
108 | // CRT equivalents. Also thanks to him for motivating me to | |
109 | // optimize my implementation of Replace() | |
110 | // | |
111 | // 2004-APR-22 - A big, big thank you to "MKingman" (whoever you are) for | |
112 | // finally spotting a silly little error in StdCodeCvt that | |
113 | // has been causing me (and users of CStdString) problems for | |
114 | // years in some relatively rare conversions. I had reversed | |
115 | // two length arguments. | |
116 | // | |
117 | // 2003-NOV-24 - Thanks to a bunch of people for helping me clean up many | |
118 | // compiler warnings (and yes, even a couple of actual compiler | |
119 | // errors). These include Henk Demper for figuring out how | |
120 | // to make the Intellisense work on with CStdString on VC6, | |
121 | // something I was never able to do. Greg Marr pointed out | |
122 | // a compiler warning about an unreferenced symbol and a | |
123 | // problem with my version of Load in MFC builds. Bill | |
124 | // Carducci took a lot of time with me to help me figure out | |
125 | // why some implementations of the Standard C++ Library were | |
126 | // returning error codes for apparently successful conversions | |
127 | // between ASCII and UNICODE. Finally thanks to Brian Groose | |
128 | // for helping me fix compiler signed unsigned warnings in | |
129 | // several functions. | |
130 | // | |
131 | // 2003-JUL-10 - Thanks to Charles Godwin for making me realize my 'FmtArg' | |
132 | // fixes had inadvertently broken the DLL-export code (which is | |
133 | // normally commented out. I had to move it up higher. Also | |
134 | // this helped me catch a bug in ssicoll that would prevent | |
135 | // compilation, otherwise. | |
136 | // | |
137 | // 2003-MAR-14 - Thanks to Jakko Van Hunen for pointing out a copy-and-paste | |
138 | // bug in one of the overloads of FmtArg. | |
139 | // | |
140 | // 2003-MAR-10 - Thanks to Ronny Schulz for (twice!) sending me some changes | |
141 | // to help CStdString build on SGI and for pointing out an | |
142 | // error in placement of my preprocessor macros for ssfmtmsg. | |
143 | // | |
144 | // 2002-NOV-26 - Thanks to Bagira for pointing out that my implementation of | |
145 | // SpanExcluding was not properly handling the case in which | |
146 | // the string did NOT contain any of the given characters | |
147 | // | |
148 | // 2002-OCT-21 - Many thanks to Paul DeMarco who was invaluable in helping me | |
149 | // get this code working with Borland's free compiler as well | |
150 | // as the Dev-C++ compiler (available free at SourceForge). | |
151 | // | |
152 | // 2002-SEP-13 - Thanks to Glen Maynard who helped me get rid of some loud | |
153 | // but harmless warnings that were showing up on g++. Glen | |
154 | // also pointed out that some pre-declarations of FmtArg<> | |
155 | // specializations were unnecessary (and no good on G++) | |
156 | // | |
157 | // 2002-JUN-26 - Thanks to Arnt Witteveen for pointing out that I was using | |
158 | // static_cast<> in a place in which I should have been using | |
159 | // reinterpret_cast<> (the ctor for unsigned char strings). | |
160 | // That's what happens when I don't unit-test properly! | |
161 | // Arnt also noticed that CString was silently correcting the | |
162 | // 'nCount' argument to Left() and Right() where CStdString was | |
163 | // not (and crashing if it was bad). That is also now fixed! | |
164 | // | |
165 | // 2002-FEB-25 - Thanks to Tim Dowty for pointing out (and giving me the fix | |
166 | // for) a conversion problem with non-ASCII MBCS characters. | |
167 | // CStdString is now used in my favorite commercial MP3 player! | |
168 | // | |
169 | // 2001-DEC-06 - Thanks to Wang Haifeng for spotting a problem in one of the | |
170 | // assignment operators (for _bstr_t) that would cause compiler | |
171 | // errors when refcounting protection was turned off. | |
172 | // | |
173 | // 2001-NOV-27 - Remove calls to operator!= which involve reverse_iterators | |
174 | // due to a conflict with the rel_ops operator!=. Thanks to | |
175 | // John James for pointing this out. | |
176 | // | |
177 | // 2001-OCT-29 - Added a minor range checking fix for the Mid function to | |
178 | // make it as forgiving as CString's version is. Thanks to | |
179 | // Igor Kholodov for noticing this. | |
180 | // - Added a specialization of std::swap for CStdString. Thanks | |
181 | // to Mike Crusader for suggesting this! It's commented out | |
182 | // because you're not supposed to inject your own code into the | |
183 | // 'std' namespace. But if you don't care about that, it's | |
184 | // there if you want it | |
185 | // - Thanks to Jason Mills for catching a case where CString was | |
186 | // more forgiving in the Delete() function than I was. | |
187 | // | |
188 | // 2001-JUN-06 - I was violating the Standard name lookup rules stated | |
189 | // in [14.6.2(3)]. None of the compilers I've tried so | |
190 | // far apparently caught this but HP-UX aCC 3.30 did. The | |
191 | // fix was to add 'this->' prefixes in many places. | |
192 | // Thanks to Farrokh Nejadlotfi for this! | |
193 | // | |
194 | // 2001-APR-27 - StreamLoad was calculating the number of BYTES in one | |
195 | // case, not characters. Thanks to Pablo Presedo for this. | |
196 | // | |
197 | // 2001-FEB-23 - Replace() had a bug which caused infinite loops if the | |
198 | // source string was empty. Fixed thanks to Eric Nitzsche. | |
199 | // | |
200 | // 2001-FEB-23 - Scott Hathaway was a huge help in providing me with the | |
201 | // ability to build CStdString on Sun Unix systems. He | |
202 | // sent me detailed build reports about what works and what | |
203 | // does not. If CStdString compiles on your Unix box, you | |
204 | // can thank Scott for it. | |
205 | // | |
206 | // 2000-DEC-29 - Joldakowski noticed one overload of Insert failed to do a | |
207 | // range check as CString's does. Now fixed -- thanks! | |
208 | // | |
209 | // 2000-NOV-07 - Aaron pointed out that I was calling static member | |
210 | // functions of char_traits via a temporary. This was not | |
211 | // technically wrong, but it was unnecessary and caused | |
212 | // problems for poor old buggy VC5. Thanks Aaron! | |
213 | // | |
214 | // 2000-JUL-11 - Joe Woodbury noted that the CString::Find docs don't match | |
215 | // what the CString::Find code really ends up doing. I was | |
216 | // trying to match the docs. Now I match the CString code | |
217 | // - Joe also caught me truncating strings for GetBuffer() calls | |
218 | // when the supplied length was less than the current length. | |
219 | // | |
220 | // 2000-MAY-25 - Better support for STLPORT's Standard library distribution | |
221 | // - Got rid of the NSP macro - it interfered with Koenig lookup | |
222 | // - Thanks to Joe Woodbury for catching a TrimLeft() bug that | |
223 | // I introduced in January. Empty strings were not getting | |
224 | // trimmed | |
225 | // | |
226 | // 2000-APR-17 - Thanks to Joe Vitaterna for pointing out that ReverseFind | |
227 | // is supposed to be a const function. | |
228 | // | |
229 | // 2000-MAR-07 - Thanks to Ullrich Poll�hne for catching a range bug in one | |
230 | // of the overloads of assign. | |
231 | // | |
232 | // 2000-FEB-01 - You can now use CStdString on the Mac with CodeWarrior! | |
233 | // Thanks to Todd Heckel for helping out with this. | |
234 | // | |
235 | // 2000-JAN-23 - Thanks to Jim Cline for pointing out how I could make the | |
236 | // Trim() function more efficient. | |
237 | // - Thanks to Jeff Kohn for prompting me to find and fix a typo | |
238 | // in one of the addition operators that takes _bstr_t. | |
239 | // - Got rid of the .CPP file - you only need StdString.h now! | |
240 | // | |
241 | // 1999-DEC-22 - Thanks to Greg Pickles for helping me identify a problem | |
242 | // with my implementation of CStdString::FormatV in which | |
243 | // resulting string might not be properly NULL terminated. | |
244 | // | |
245 | // 1999-DEC-06 - Chris Conti pointed yet another basic_string<> assignment | |
246 | // bug that MS has not fixed. CStdString did nothing to fix | |
247 | // it either but it does now! The bug was: create a string | |
248 | // longer than 31 characters, get a pointer to it (via c_str()) | |
249 | // and then assign that pointer to the original string object. | |
250 | // The resulting string would be empty. Not with CStdString! | |
251 | // | |
252 | // 1999-OCT-06 - BufferSet was erasing the string even when it was merely | |
253 | // supposed to shrink it. Fixed. Thanks to Chris Conti. | |
254 | // - Some of the Q172398 fixes were not checking for assignment- | |
255 | // to-self. Fixed. Thanks to Baptiste Lepilleur. | |
256 | // | |
257 | // 1999-AUG-20 - Improved Load() function to be more efficient by using | |
258 | // SizeOfResource(). Thanks to Rich Zuris for this. | |
259 | // - Corrected resource ID constructor, again thanks to Rich. | |
260 | // - Fixed a bug that occurred with UNICODE characters above | |
261 | // the first 255 ANSI ones. Thanks to Craig Watson. | |
262 | // - Added missing overloads of TrimLeft() and TrimRight(). | |
263 | // Thanks to Karim Ratib for pointing them out | |
264 | // | |
265 | // 1999-JUL-21 - Made all calls to GetBuf() with no args check length first. | |
266 | // | |
267 | // 1999-JUL-10 - Improved MFC/ATL independence of conversion macros | |
268 | // - Added SS_NO_REFCOUNT macro to allow you to disable any | |
269 | // reference-counting your basic_string<> impl. may do. | |
270 | // - Improved ReleaseBuffer() to be as forgiving as CString. | |
271 | // Thanks for Fan Xia for helping me find this and to | |
272 | // Matthew Williams for pointing it out directly. | |
273 | // | |
274 | // 1999-JUL-06 - Thanks to Nigel Nunn for catching a very sneaky bug in | |
275 | // ToLower/ToUpper. They should call GetBuf() instead of | |
276 | // data() in order to ensure the changed string buffer is not | |
277 | // reference-counted (in those implementations that refcount). | |
278 | // | |
279 | // 1999-JUL-01 - Added a true CString facade. Now you can use CStdString as | |
280 | // a drop-in replacement for CString. If you find this useful, | |
281 | // you can thank Chris Sells for finally convincing me to give | |
282 | // in and implement it. | |
283 | // - Changed operators << and >> (for MFC CArchive) to serialize | |
284 | // EXACTLY as CString's do. So now you can send a CString out | |
285 | // to a CArchive and later read it in as a CStdString. I have | |
286 | // no idea why you would want to do this but you can. | |
287 | // | |
288 | // 1999-JUN-21 - Changed the CStdString class into the CStdStr template. | |
289 | // - Fixed FormatV() to correctly decrement the loop counter. | |
290 | // This was harmless bug but a bug nevertheless. Thanks to | |
291 | // Chris (of Melbsys) for pointing it out | |
292 | // - Changed Format() to try a normal stack-based array before | |
293 | // using to _alloca(). | |
294 | // - Updated the text conversion macros to properly use code | |
295 | // pages and to fit in better in MFC/ATL builds. In other | |
296 | // words, I copied Microsoft's conversion stuff again. | |
297 | // - Added equivalents of CString::GetBuffer, GetBufferSetLength | |
298 | // - new sscpy() replacement of CStdString::CopyString() | |
299 | // - a Trim() function that combines TrimRight() and TrimLeft(). | |
300 | // | |
301 | // 1999-MAR-13 - Corrected the "NotSpace" functional object to use _istpace() | |
302 | // instead of _isspace() Thanks to Dave Plummer for this. | |
303 | // | |
304 | // 1999-FEB-26 - Removed errant line (left over from testing) that #defined | |
305 | // _MFC_VER. Thanks to John C Sipos for noticing this. | |
306 | // | |
307 | // 1999-FEB-03 - Fixed a bug in a rarely-used overload of operator+() that | |
308 | // caused infinite recursion and stack overflow | |
309 | // - Added member functions to simplify the process of | |
310 | // persisting CStdStrings to/from DCOM IStream interfaces | |
311 | // - Added functional objects (e.g. StdStringLessNoCase) that | |
312 | // allow CStdStrings to be used as keys STL map objects with | |
313 | // case-insensitive comparison | |
314 | // - Added array indexing operators (i.e. operator[]). I | |
315 | // originally assumed that these were unnecessary and would be | |
316 | // inherited from basic_string. However, without them, Visual | |
317 | // C++ complains about ambiguous overloads when you try to use | |
318 | // them. Thanks to Julian Selman to pointing this out. | |
319 | // | |
320 | // 1998-FEB-?? - Added overloads of assign() function to completely account | |
321 | // for Q172398 bug. Thanks to "Pete the Plumber" for this | |
322 | // | |

374 | // ------------------ | |
375 | // This macro causes the addition of a constructor and assignment operator | |
376 | // which take unsigned characters. CString has such functions and in order | |
377 | // to provide maximum CString-compatability, this code needs them as well. | |

386 | // MACRO: SS_SAFE_FORMAT | |
387 | // --------------------- | |
388 | // This macro provides limited compatability with a questionable CString | |
389 | // "feature". You can define it in order to avoid a common problem that | |
390 | // people encounter when switching from CString to CStdString. | |
391 | // | |
392 | // To illustrate the problem -- With CString, you can do this: | |
393 | // | |
394 | // CString sName("Joe"); | |
395 | // CString sTmp; | |
396 | // sTmp.Format("My name is %s", sName); // WORKS! | |
397 | // | |
398 | // However if you were to try this with CStdString, your program would | |
399 | // crash. | |
400 | // | |
401 | // CStdString sName("Joe"); | |
402 | // CStdString sTmp; | |
403 | // sTmp.Format("My name is %s", sName); // CRASHES! | |
404 | // | |
405 | // You must explicitly call c_str() or cast the object to the proper type | |
406 | // | |
407 | // sTmp.Format("My name is %s", sName.c_str()); // WORKS! | |
408 | // sTmp.Format("My name is %s", static_cast<PCSTR>(sName));// WORKS! | |
409 | // sTmp.Format("My name is %s", (PCSTR)sName); // WORKS! | |
410 | // | |
411 | // This is because it is illegal to pass anything but a POD type as a | |
412 | // variadic argument to a variadic function (i.e. as one of the "..." | |
413 | // arguments). The type const char* is a POD type. The type CStdString | |
414 | // is not. Of course, neither is the type CString, but CString lets you do | |
415 | // it anyway due to the way they laid out the class in binary. I have no | |
416 | // control over this in CStdString since I derive from whatever | |
417 | // implementation of basic_string is available. | |
418 | // | |
419 | // However if you have legacy code (which does this) that you want to take | |
420 | // out of the MFC world and you don't want to rewrite all your calls to | |
421 | // Format(), then you can define this flag and it will no longer crash. | |

1806 | // | |
1807 | // DESCRIPTION: | |
1808 | // This function is very much (but not exactly) like strcpy. These | |
1809 | // overloads simplify copying one C-style string into another by allowing | |
1810 | // the caller to specify two different types of strings if necessary. | |
1811 | // | |
1812 | // The strings must NOT overlap | |
1813 | // | |
1814 | // "Character" is expressed in terms of the destination string, not | |
1815 | // the source. If no 'nMax' argument is supplied, then the number of | |
1816 | // characters copied will be sslen(pSrc). A NULL terminator will | |
1817 | // also be added so pDst must actually be big enough to hold nMax+1 | |
1818 | // characters. The return value is the number of characters copied, | |
1819 | // not including the NULL terminator. | |
1820 | // | |
1821 | // PARAMETERS: | |
1822 | // pSrc - the string to be copied FROM. May be a char based string, an | |
1823 | // MBCS string (in Win32 builds) or a wide string (wchar_t). | |
1824 | // pSrc - the string to be copied TO. Also may be either MBCS or wide | |
1825 | // nMax - the maximum number of characters to be copied into szDest. Note | |
1826 | // that this is expressed in whatever a "character" means to pDst. | |
1827 | // If pDst is a wchar_t type string than this will be the maximum | |
1828 | // number of wchar_ts that my be copied. The pDst string must be | |
1829 | // large enough to hold least nMaxChars+1 characters. | |
1830 | // If the caller supplies no argument for nMax this is a signal to | |
1831 | // the routine to copy all the characters in pSrc, regardless of | |
1832 | // how long it is. | |
1833 | // | |
1834 | // RETURN VALUE: none | |

2610 | // Answer: One reason only - CString compatability. In short, by making | |
2611 | // the Format() function a template this way, I can do strong typing | |
2612 | // and allow people to pass CStdString arguments as fillers for | |

3872 | // MSVC USERS: HOW TO EXPORT CSTDSTRING FROM A DLL | |
3873 | // | |
3874 | // If you are using MS Visual C++ and you want to export CStdStringA and | |
3875 | // CStdStringW from a DLL, then all you need to | |
3876 | // | |
3877 | // 1. make sure that all components link to the same DLL version | |
3878 | // of the CRT (not the static one). | |
3879 | // 2. Uncomment the 3 lines of code below | |
3880 | // 3. #define 2 macros per the instructions in MS KnowledgeBase | |
3881 | // article Q168958. The macros are: | |
3882 | // | |
3883 | // MACRO DEFINTION WHEN EXPORTING DEFINITION WHEN IMPORTING | |
3884 | // ----- ------------------------ ------------------------- | |
3885 | // SSDLLEXP (nothing, just #define it) extern | |
3886 | // SSDLLSPEC __declspec(dllexport) __declspec(dllimport) | |
3887 | // | |
3888 | // Note that these macros must be available to ALL clients who want to | |
3889 | // link to the DLL and use the class. If they | |
3890 | // | |
3891 | // A word of advice: Don't bother. | |
3892 | // | |
3893 | // Really, it is not necessary to export CStdString functions from a DLL. I | |
3894 | // never do. In my projects, I do generally link to the DLL version of the | |
3895 | // Standard C++ Library, but I do NOT attempt to export CStdString functions. | |
3896 | // I simply include the header where it is needed and allow for the code | |
3897 | // redundancy. | |
3898 | // | |
3899 | // That redundancy is a lot less than you think. This class does most of its | |
3900 | // work via the Standard C++ Library, particularly the base_class basic_string<> | |
3901 | // member functions. Most of the functions here are small enough to be inlined | |
3902 | // anyway. Besides, you'll find that in actual practice you use less than 1/2 | |
3903 | // of the code here, even in big projects and different modules will use as | |
3904 | // little as 10% of it. That means a lot less functions actually get linked | |
3905 | // your binaries. If you export this code from a DLL, it ALL gets linked in. | |
3906 | // | |
3907 | // I've compared the size of the binaries from exporting vs NOT exporting. Take | |
3908 | // my word for it -- exporting this code is not worth the hassle. | |
