MFC detects a file exists, gets the current path, creates a new folder

Directly on the code:

See if there is a DB folder under the path to the execution file, and if not, create a new/////////

CFileFind CFF;
if (CFF. FindFile (_t ("db")) = = 0)//current path, DB folder not found
{
CString StrText;
TCHAR exepath[max_path]={0};
:: GetModuleFileName (Null,exepath,max_path); Get exe path, stored in ExePath
Strtext=exepath;
StrText = Strtext.left (strtext.reversefind (' \ \ ')); Find the first/last number in the path, and then pinch off the characters that follow it, paying attention to the expression of the escape character \ \
StrText + = _t ("\ \");
StrText + = _t ("db"); New path, new file name
CreateDirectory (Strtext,null); Generate DB Folder
}

The following is reproduced, not verified

1. Get the path where debug or release is located
CString Getmoduledir ()
{
hmodule module = getmodulehandle (0);
Char Pfilename[max_path];
GetModuleFileName (module, Pfilename, MAX_PATH);

CString Csfullpath (pfilename);
int nPos = Csfullpath.reversefind (_t (' \ \ '));
if (NPos < 0)
Return CString ("");
Else
Return Csfullpath.left (NPos);
}

2. Get the current working path (the path where the DSP is located)

Get Work Path
CString Getworkdir ()
{
Char Pfilename[max_path];
int nPos = GetCurrentDirectory (MAX_PATH, pfilename);

CString Csfullpath (pfilename);
if (NPos < 0)
Return CString ("");
Else
return csfullpath;
}

C/mfc How to get the application's current path (grooming)

The first method:DWORD GetCurrentDirectory (
DWORD nbufferlength,//size, in characters, of directory buffer
LPTSTR lpbuffer//pointer to buffer for current directory
);
BOOL SetCurrentDirectory (
LPCTSTR lppathname//Pointer to name of the new current directory
);
The second method ofUse GetModuleFileName to get the file name of the application (the first parameter is null)
Then use _splitpath to parse the file name to get the path for example://Get current path
/*char buf[100];
GetCurrentDirectory (sizeof (BUF), buf);
MessageBox (BUF);
HINSTANCE Hinst=null;
Hinst=afxgetapp ()->m_hinstance;
Char Path_buffer[_max_path];
GetModuleFileName (hinst,path_buffer,sizeof (Path_buffer));//Get the full path of EXE file
Detaches the path and file name.
Char drive[_max_drive];
Char Dir[_max_dir];
Char Fname[_max_fname];
Char Ext[_max_ext];
_splitpath (Path_buffer, Drive, dir, fname, ext);
CString Path;
Path.format ("%s%s", Drive,dir); char path[300];strcpy (path,drive);
strcat (Path,dir); or:TCHAR Exefullpath[max_path];
CString strpath;
GetModuleFileName (Null,exefullpath,max_path);
Strpath= (CString) Exefullpath;
intPosition=strpath.reversefind (' \ \ ');
Strpath=strpath.left (position+1);

TCHAR Filepath[max_path];
GetModuleFileName (Null,filepath,max_path);
(_TCSRCHR (FilePath, ' \ \ ')) [1] = 0;
Lstrcat (filepath,_t ("My.ini"));

The third method:VC __argv[0] can get EXE program name, and then use _splitpath can be decomposed to get the program path. Fourth Method#include <direct.h>char buf[_max_path];_getcwd (Buf,_max_path); the fourth is to get the directory where the operating system is located char buf[100];
GetSystemDirectory (buf,100);
MessageBox (BUF);the following is not verifiedHttp://www.cnblogs.com/project/archive/2010/12/02/1894494.html
