在线列印第三方调用接口介绍

Perfect design makes things easier! -- syant

有些产测解决方案(ATE)，在执行产测功能测试后可能还需要打印出标签。内容简单的标签可以由产测软件来完成，但如果涉及到复杂内容的标签打印，可以由产测软件调用MES的在线列印接口，让MES来完成标签的打印。

MES在线打印程序支持第三方的调用，调用过程很简单，是一个DLL形式封装的StdCall函数，提供VB, Delphi, C++, C#范例。 产测程序调用接口函数传给MES产品主条码后，MES会继续完成打印工作，并执行包括数据逻辑检查，模板监控，打印防呆和数据追溯等等MES功能。

Delphi调用范例

const
    DLLNAME3  = 'CloudMes_sdk_005.dll';

procedure mes_data_print(str:string);
function mes_ret:string;

implementation

procedure _mes_data(warn:pchar;len:integer);stdcall; external DLLNAME3 name 'mes_data';
procedure _mes_print;stdcall; external DLLNAME3 name 'mes_print';
procedure _mes_data_print(warn:pchar;len:integer);stdcall; external DLLNAME3 name 'mes_data_print';
procedure _mes_ret(warn:pchar;len:integer);stdcall; external DLLNAME3 name 'mes_ret';

procedure mes_data_print(str:string);
begin
  _mes_data_print(pchar(Str),length(Str));
end;

function mes_ret:string;
var
  buf:array[0..1000] of char;
begin
  _mes_ret(buf,1000);
  result:=string(buf);
end;

procedure TForm1.Button1Click(Sender: TObject);
var
 s:string;
 i:integer;
begin
  s:=formatdatetime('yyyymmddhhnnss',now);
  mes_data_print(s);   //
  //
  i:=20; s:=''; memo1.Lines.Clear;
  while(i>0)do
  begin
    s:=mes_ret;
    memo1.Lines.Add('=>'+s);
    if(s<>'')then break;
    sleep(100);
    application.ProcessMessages ;
    i:=i-1;
  end;
end;

VB调用范例

Public Declare Sub mes_data_print Lib "CloudMes_sdk_005" (ByVal warn As String, ByVal slen As Integer)
Public Declare Sub mes_ret Lib "CloudMes_sdk_005" (ByVal warn As String, ByVal slen As Integer)


Public Sub mesprint(ByVal warn As String)
Dim i As Integer
i = LenB(warn)
mes_data_print warn, i
End Sub

Public Function mesret() As String
res$ = Space(1000)
mes_ret res$, 1000
mesret = res
End Function

Private Sub Command1_Click()
Dim s As String
Dim i As Integer
Dim tick As Single
s = Format(Now, "yyyyMMddHHnnss")
mesprint (s)
s = ""
i = 0
tick = Timer
While i < 10 And Len(s) < 5
    s = Trim(mesret)
    Sleep 200
    DoEvents
    i = i + 1
Wend
Me.Label1.Caption = i & "==>" & s & "<=="
End Sub
