VC文件遍历代码问题

Question

我把源码上传到http://u.115.com/file/t187b15d56语法没问题就是不知为什么没效果，求改正

Answer 1

void CTestDlg::Findfile(CString strl, HTREEITEM h)
{
CTreeCtrl*pTree=(CTreeCtrl*)GetDlgItem(IDC_TREE);
//下面进行搜索实现文件遍历
CFileFind filefind;
CString filepath;
CString filename = strl;
tvinsert.hParent=h;
tvinsert.item.iImage=0;
tvinsert.item.iSelectedImage=0;

BOOL flag=filefind.FindFile(filename );//查找文件
while(flag)
{
flag=filefind.FindNextFile();
if(filefind.IsDots())
continue;
else
if(filefind.IsDirectory())//是目录则需要对目录继续遍历
{
filename=filefind.GetFileName();
tvinsert.item.pszText=strdup(filename);
tvinsert.hParent=h;
hDad=pTree->InsertItem(&tvinsert);
Findfile(filefind.GetFilePath()+"\\*.*",hDad);//递归查找文件
}
else
{
tvinsert.hParent=h;
filename=filefind.GetFileName();//得到文件名
tvinsert.item.pszText=strdup(filename);
pTree->InsertItem(&tvinsert);//插入一项
}
}
}

给个例子：char    FolderPath[MAX_PATH];
__int64 FolderSize=0;
int     FilesContained=0;
int     FoldersContained=0;
////
void FolderWalkRecurse(LPDIRWALKDATA pDW)
{
char szCurrDir[MAX_PATH];
HANDLE hFind;
char tmp[MAX_PATH];// set new path
sprintf(szCurrDir,"%s%s",FolderPath,"*.*");
hFind=FindFirstFile(szCurrDir,&pDW->FindData);
pDW->fOK=(hFind!=INVALID_HANDLE_VALUE);
while(pDW->fOK) // found 
{  // till found 
pDW->fIsDir=pDW->FindData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY;
GetFilePart(FolderPath,tmp);// dir for recurse!
sprintf(tmp,"%s",pDW->FindData.cFileName);
if(strcmp(tmp,".") && strcmp(tmp,"..")) //not
{
if(pDW->fIsDir)
{
FoldersContained++;
}
else
{
FolderSize+=(pDW->FindData.nFileSizeHigh<<32) +
pDW->FindData.nFileSizeLow;
FilesContained++;
}
}
pDW->fOK=FindNextFile(hFind,&pDW->FindData);
}
if(hFind!=INVALID_HANDLE_VALUE) FindClose(hFind);// handle bad
if(pDW->fRecurse)
{// handle OK.get the first child directory
sprintf(szCurrDir,"%s%s",FolderPath,"*.*");
hFind=FindFirstChildDir(szCurrDir,&pDW->FindData);
pDW->fOK=(hFind!=INVALID_HANDLE_VALUE);
while (pDW->fOK)
{ // change into the child directory
sprintf(szCurrDir,"%s%s\\",FolderPath,pDW->FindData.cFileName);
strcpy(FolderPath,szCurrDir);
// AfxMessageBox(CString("enter Directory")+FolderPath,MB_OK);
FolderWalkRecurse(pDW);// Perform the recursive walk.
// change back to child's parent directory//
GetPathPart(FolderPath);
// AfxMessageBox(CString("leave Directory ")+FolderPath,MB_OK);
pDW->fOK=FindNextChildDir(hFind,&pDW->FindData);
}
if (hFind!=INVALID_HANDLE_VALUE) FindClose(hFind);
}
}
////
void FolderWalk(char *RootPath,BOOL fRecurse)
{ 
DIRWALKDATA DW;
// set new path
strcpy(FolderPath,RootPath);
// call the recursive function to walk the subdirectory
DW.fRecurse=fRecurse;
FolderWalkRecurse(&DW);
}、、
typedef struct
{
HWND            hwndTreeLB;
BOOL            fIsList;
BOOL            fRecurse;
BOOL fOK;
BOOL fIsDir;
WIN32_FIND_DATA FindData;  
}DIRWALKDATA, * LPDIRWALKDATA;
