[DELPHI]目录完全删除(deltree)
procedure TForm1.DeleteDirectory(strDir:String);
var
sr: TSearchRec;
FileAttrs: Integer;
strfilename:string;
strPth:string;
begin
strpth:=Getcurrentdir();
FileAttrs := faAnyFile;
if FindFirst(strpth+'\'+strdir+'\*.*', FileAttrs, sr) = 0 then
begin
if (sr.Attr and FileAttrs) = sr.Attr then
begin
strfilename:=sr.Name;
if fileexists(strpth+'\'+strdir+'\'+strfilename) then
deletefile(strpth+'\'+strdir+'\'+strfilename);
end;
while FindNext(sr) = 0 do
begin
if (sr.Attr and FileAttrs) = sr.Attr then
begin
strfilename:=sr.name;
if fileexists(strpth+'\'+strdir+'\'+strfilename) then
deletefile(strpth+'\'+strdir+'\'+strfilename);
end;
end;
FindClose(sr);
removedir(strpth+'\'+strdir);
end;
end;
[DELPHI]取得TMemo 控件当前光标的行和列信息到Tpoint中
1.function ReadCursorPos(SourceMemo: TMemo): TPoint;
var Point: TPoint;
begin
point.y := SendMessage(SourceMemo.Handle,EM_LINEFROMCHAR,SourceMemo.SelStart,0);
point.x := SourceMemo.SelStart-SendMessage(SourceMemo.Handle,EM_LINEINDEX,point.y,0);
Result := Point;
end;
2.LineLength:=SendMessage(memol．handle,EM-LINELENGTH,Cpos,0);//行长 |
