So, here to remind you, although in general by default, the current EXE directory is the same as the EXE process's current directory, but it is best not to use the GetCurrentDirectory function to get the current EXE directory, there are potential problems, such as: TCHAR szpath [MAX_PATH] = {0}; GetCurrentDirectory (MAX_PATH, szpath); MessageBox (szpath); cfiledialog dlg (FALSE);d Lg. DoModal (); getcurrentdirectory (MAX_PATH, szpath); MessageBox (szpath); ④, executable directory [includes EXE and Dll];dword getcurrentfolder (DWORD nbufferlength, LPTSTR lpbuffer) { dword Dwret = 0; cstring strpath; getmodulefilename (AfxGetInstanceHandle (), Strpath.getbuffersetlength (MAX_PATH), MAX_PATH); strpath.releasebuffer (); int idx = Strpath.reversefind (' \ \ '); if (idx >= 0) { strpath = strpath.left (idx); } else { return 0; } dwret = Strpath.getlength (); _tcsncpy_s (lpbuffer, Nbufferlength, strpath, dwRet); dwRet = ( Nbufferlength >= dwret)? Dwret:nbufferlength; return Dwret;} ⑤, the project current directory and debug debug directory different: The VC Start Program and mouse double-click Start Program, observe the call getcurrentdirectory function to obtain the results of the difference! So: Sometimes you will be prompted not to find the DLL and other errors! ⑥⑦⑧⑨⑩ System Information Acquisition ①, current user name, computer name acquisition; ②, CPU, memory, hard disk information acquisition. ★-------------------------------------End-------------------------------------------
