in the VS2008 ide, i write a wrapper to encapsulate the VC dll(vc.dll) to be a Com(com.dll) and the vc.dll will be called by c.exe
qutsion#1: i found the compile option for vc.dll was Char Set:Not Set my question is, Which Char Set should i use to compile the com project?
question#2: if we set the Char set to be Not Set also for the com project ,then how should i handle the string in the interface of the functions? because there are many string types such as TCHAR and BSTR and _bstr_t which one is better for my Com project?
question#3: how should i set the Char Set for the C project(C.exe)?
