cstring

My company use some code like this: std::string(CT2CA(some_CString)).c_str() which I believe it converts a Unicode string (whose type is CString)into ANSI encoding, and this string is for a email's subject. However, header of the email (which includes the subject) indicates that the mail client should decode it as a unicode (this is how the original code does). Thus, some German chars like "ä ö ü" will not be properly displayed as the title. Is there anyway that I can put this header back to UTF8 and store into a std::string or const char*? I know there are a lot of smarter ways to do this,

This is my main(): char * cString; puts("Please enter data you want to encrypt."); cString = getInput(cString, &iStringSize); printf("The message is: %s\n\n", cString); char * strEncrypt; strEncrypt = encrypt(cString, offset); printf("The encrypted message is: %s\n\n", strEncrypt); return 0; This program basically reads in an arbitrary input, then encrypt it. This is the getInput function: char * getInput(char *cString, int * iStringSize) { puts("Begin reading input.");

I tried stl-strings, but visual studio 2008- accumulates bugs in stl-wstring-handling. I will say a lot about that thing later, in other question. Now Can anybody shed light on this issue? 回答1: Use the conversion class CT2CW like this FuncTakingLPCWSTR(CT2CW(cstring_var)) . This is guaranteed to work in either Unicode or MBCS builds. Also, keep in mind that the string passed to the function may be a temporary, so don't store

I need to convert double value to CString, because i need to do AfxMessageBox(double_value); I find this: std::ostringstream ost; ost << double_value; std::cout << "As string: " << ost.str() << std::endl; //AfxMessageBox(ost.str()); - Does not work. How i can do this? 回答1: AfxMessageBox expects a CString object, so format the double into a CString and pass that: CString str; str.Format("As string: %g", double); AfxMessageBox(str); Edit: If you want the value displayed as an integer (no value after decimal point) then

As this code is used in many places throughout the codebase, I want to try and keep it simple and in a single function or object so I only have to declare them once. From my reading it looks like CMap is the tool for the job, but I can't seem to discover any combination of template arguments that compiles without errors. My values are CString and int . I tried the following definition: CMap<int, int, CString,

At some point, I have to write UTF-8 data into a file; to do that, I'm using CFiles and CStrings. When I get to write utf-8 (russian characters, to be more precise) data into a file, the output looks like and etc. This is assurely not utf-8. To read this data properly, I have to change my system settings; changing non ASCII characters to a russian encoding table does work, but then all my latin based non-ascii characters get to fail. Anyway, that's how I do it.
