Thread: deleting directory structure routine (with code tags this time)

Hi!


I'm a VC++ programmer. I need a recursive routine that deletes all the subdirs and files from within a parent(root) directory. This root directory should be taken as a parameter (LPCTSTR or CString) when you call the function.
Here is some code which compiles but doesn't do it's job (deleting):

// This macro evaluates to the number of elements in an array.
#define chDIMOF(Array) (sizeof(Array) / sizeof(Array[0]))

typedef struct
{
int nDepth; // Nesting depth
BOOL fRecurse; // Set to TRUE to list subdirectories
TCHAR szBuf[1000]; // Output formatting buffer
int nIndent; // Indentation character count
BOOL fOk; // Loop control flag
BOOL fIsDir; // Loop control flag
WIN32_FIND_DATA FindData; // File information
} DIRWALKDATA, *LPDIRWALKDATA;

static void RemoveDirRecurse(LPDIRWALKDATA pDW)
{
HANDLE hFind;

pDW->nDepth++;

pDW->nIndent = 3 * pDW->nDepth;
_stprintf(pDW->szBuf, _TEXT("%*s"), pDW->nIndent, _TEXT(""));

GetCurrentDirectory(chDIMOF(pDW->szBuf) - pDW->nIndent, &pDW->szBuf[pDW->nIndent]);
// ***
::RemoveDirectory(pDW->szBuf);

hFind = FindFirstFile(_TEXT("*.*"), &pDW->FindData);
pDW->fOk = (hFind != INVALID_HANDLE_VALUE);

while (pDW->fOk)
{
pDW->fIsDir = pDW->FindData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY;
if (!pDW->fIsDir || (!pDW->fRecurse && IsChildDir(&pDW->FindData)))
{
_stprintf(pDW->szBuf,
pDW->fIsDir ? _TEXT("%*s[%s]") : _TEXT("%*s%s"),
pDW->nIndent, _TEXT(""),
pDW->FindData.cFileName);

//***
:eleteFile(pDW->szBuf);
}
pDW->fOk = FindNextFile(hFind, &pDW->FindData);
}
if (hFind != INVALID_HANDLE_VALUE)
FindClose(hFind);

if (pDW->fRecurse)
{
// Get the first child directory
hFind = FindFirstChildDir(_TEXT("*.*"), &pDW->FindData);
pDW->fOk = (hFind != INVALID_HANDLE_VALUE);
while (pDW->fOk)
{
// Change into the child directory
if (SetCurrentDirectory(pDW->FindData.cFileName))
{
// Perform the recursive walk into the child directory.
// Remember that some members of pDW will be overwritten by this call.
RemoveDirRecurse(pDW);

// Change back to the child's parent directory.
SetCurrentDirectory(_TEXT(".."));
}
pDW->fOk = FindNextChildDir(hFind, &pDW->FindData);
}
if (hFind != INVALID_HANDLE_VALUE)
FindClose(hFind);
}
pDW->nDepth--;
}


void CAfisare::RemoveCurDir(LPCTSTR pszRootPath, BOOL fRecurse)
{
TCHAR szCurrDir[_MAX_DIR];
DIRWALKDATA DW; // Create instance of DIRWALKDATA

// Save the current directory so that it can be restored later.
GetCurrentDirectory(chDIMOF(szCurrDir), szCurrDir);

// Set the current directory to where you want to start walking
SetCurrentDirectory(pszRootPath);

// nDepth is used to control indenting. The value -1 will cause
// the first level to display flush left.
DW.nDepth = -1;
DW.fRecurse = fRecurse;

RemoveDirRecurse(&DW);

// Restore the current directory to what it was before the function was called.
SetCurrentDirectory(szCurrDir);
}

void CAfisare::OnTest()
{
CString strRootPath = "C:\\KE1c_SL";
RemoveCurDir(strRootPath, TRUE);
}

Maybe you have a better idea,
