获取指定目录下的所有目录列表(包括子目录)，

Question

获取指定目录下的所有目录列表(包括子目录)，将结果在listview中以树状显示出来。顶做？

Answer 1

目录形式为 ： 'd:\winnt\system32\*.*' 形式
用 字符串查找 和 字符串拷贝 来获取每一个子目录名， 并加到treeview中去

Answer 2

我用的是AHM控件组里的Folder很好用的

Answer 3

使用F: TSearchRec；
下面有段例子是删除的，稍改一下就行了
procedure DeleteDir(aPath:string);
var  path:string;FindState:integer; F: TSearchRec;
begin
     if copy(aPath,length(trim(aPath)),1)='\' then
        apath:=copy(aPath,1,length(apath)-1);
     path:=aPath+'\*.*';
     FindState:=FindFirst(Path,faAnyFile,F);
     while FindState=0 do
     begin
          if pos('.',f.name)=1 then
          else
          begin
               FileSetAttr(aPath+'\'+f.name,128);
               DeleteFile(aPath+'\'+f.name);
          end;
          FindState:=FindNext(F);
     end;     FindState:=FindFirst(Path,faDirectory,F);
     while FindState=0 do
     begin
          if pos('.',f.name)=1 then
          else DeleteDir(aPath+'\'+f.name);
          FindState:=FindNext(F);
     end;
end;
