我自己写的几个C++常用方法

void FolderCopy(char src,char dst);//文件夹拷贝，将src文件夹下的所有内容拷贝到dst下，如果不存在dst,则创建之
voidCMyCommon::FolderCopy(charsrc,chardst)

{

CreateDirectoryA(dst,NULL);

charsrcPath[250];

chardstPath[250];



HANDLE hFind;

WIN32_FIND_DATAA FindFileData;

//char line[1024];

charpath[260];

sprintf(path,"%s\",src);

hFind=FindFirstFileA(path,&FindFileData);

if(INVALID_HANDLE_VALUE==hFind)

return;

do{

printf("%s\n",FindFileData.cFileName);

if(FindFileData.dwFileAttributes&FILE_ATTRIBUTE_DIRECTORY)

{

//printf("%s\n",FindFileData.cFileName);

if(FindFileData.cFileName[0]!='.')

{

sprintf(srcPath,"%s\%s",src,FindFileData.cFileName);

sprintf(dstPath,"%s\%s",dst,FindFileData.cFileName);

CreateDirectoryA(dstPath,NULL);

this->FolderCopy(srcPath,dstPath);

}

}else{

sprintf(srcPath,"%s\%s",src,FindFileData.cFileName);

sprintf(dstPath,"%s\%s",dst,FindFileData.cFileName);

CopyFileA(srcPath,dstPath,TRUE);

}

}while(FindNextFileA(hFind,&FindFileData));

/

MFC:

SHFILEOPSTRUCT lpFileOp;

lpFileOp.hwnd = GetSafeHwnd();//执行文件复制

lpFileOp.wFunc = FO_COPY;

lpFileOp.pFrom = (LPCWSTR)src;

lpFileOp.pTo = (LPCWSTR)dst;

lpFileOp.fFlags = FOF_ALLOWUNDO;//保存UNDO信息，以便 在回收站中恢复文件

lpFileOp.fAnyOperationsAborted = FALSE;

lpFileOp.hNameMappings = NULL;

lpFileOp.lpszProgressTitle = L"正在复制";

int nReturnValue = SHFileOperation(&lpFileOp);

if(nReturnValue == 0)

{

if(lpFileOp.fAnyOperationsAborted == TRUE){

//"复制文件夹的操作被取消"

printf("复制文件夹的操作被取消\n");

}else {

//"复制文件夹操作成功！"

printf("复制文件夹操作成功！\n");

}

}else {

//复制文件夹操作失败

printf("复制文件夹操作失败\n");

}
