The GetCurrentDirectory function retrieves the current directory for the current process. DWORD GetCurrentDirectory( DWORD nBufferLength, // size, in characters, of directory buffer LPTSTR lpBuffer // pointer to buffer for current directory );
DWORD GetModuleFileName( HMODULE hModule, // handle to module to find filename for LPTSTR lpFilename, // pointer to buffer to receive module path DWORD nSize // size of buffer, in characters );
Parameters hModule Handle to the module whose executable filename is being requested. If this parameter is NULL, GetModuleFileName returns the path for the file used to create the calling process. lpFilename Pointer to a buffer that is filled in with the path and filename of the given module. nSize Specifies the length, in characters, of the lpFilename buffer. If the length of the path and filename exceeds this limit, the string is truncated. //这个处理一下也可以

Parameters
hModule
Handle to the module whose executable filename is being requested. If this parameter is NULL, GetModuleFileName returns the path for the file used to create the calling process.
lpFilename
Pointer to a buffer that is filled in with the path and filename of the given module.
nSize
Specifies the length, in characters, of the lpFilename buffer. If the length of the path and filename exceeds this limit, the string is truncated.
//这个处理一下也可以
GetModuleFileName就可以了,然后截取后面的路径就行了
char ch[256];
GetModuleFileName(hModule,ch,255);
for(int i=strlen(ch);i && ch[i]!='\\';i--);
ch[i]=0;C似易似难人难断
memset(szAppPath, 0, MAX_PATH);
GetModuleFileName(NULL, szAppPath, MAX_PATH);
CString str;
str.Format("%s", szAppPath);
str = str.Left(str.ReverseFind('\\') + 1);
以上只是一种方法，其它的自己再慢慢研究。
