为什么不能将TCHAR *转换为char * [英] Why can't convert TCHAR* to char*
问题描述
错误C2664:'strcpy':无法将参数1从'TCHAR *'转换为'char *'
代码:
error C2664: 'strcpy' : cannot convert parameter 1 from 'TCHAR *' to 'char *' code:
LPCTSTR name, DWORD value
strcpy (&this->valueName[0], name);
错误C2664:'strlen':无法将参数1从'LPCTSTR'转换为'const char *'
error C2664: 'strlen' : cannot convert parameter 1 from 'LPCTSTR' to 'const char *'
LPCTSTR name;
strlen (name)
上面的代码可以在另一个项目中正常工作,我找不到为什么它不工作在这个MS VS2010项目的原因。
The code above to a class which works fine in another project, I can't find the reason why it doesn't work in this MS VS2010 Project.
推荐答案
例如定义_UNICODE时的 wcstombs 。或者只需使用 _tcslen (查看 Generic-文本例程映射)在TCHAR字符串上,编译器会将其传输到strlen或wcslen,取决于您是否使用unicode。
You need to use a function such as wcstombs when _UNICODE is defined. Either that or just use _tcslen (Look under Generic-Text Routine Mappings) on the TCHAR string and the compiler will transfer it to either strlen or wcslen depending if you are using unicode or not.
