vc知识积累(4.文件操作)

1. 查询某目录下全部文件:

CFileFind cff;

CString dir( "E://English//family" );

if( cff.FindFile( dir + "//*.*" ) )

{

while( cff.FindNextFile() )

{

CString filename = cff.GetFileName();

}

}

2. 创建新目录

CString newDir( "E://English//走遍美国" );

CreateDirectory( newDir, NULL );

3. 拷贝文件

CString oldFileName;

oldFileName.Format( "%s//%s", oldDir, oldFileName );

CString newFileName;

newFileName.Format( "%s//%s", newDir, newFileName );

CopyFile( sourceFileName, destFileName, FALSE );
