我处对TCnDebugger.InternalOutputMsg做以下调整，这样可以在没有安装查看器的情况下，输入到文件，这样可以在普通用户使用时，作为跟踪器使用，强烈希望管理员能调整。

或者有更好方法也行。。。

procedure TCnDebugger.InternalOutputMsg(const AMsg: AnsiString; Size: Integer;
  const ATag: AnsiString; ALevel, AIndent: Integer; AType: TCnMsgType;
  ThreadID: DWORD; CPUPeriod: Int64);
var
  TagLen, MsgLen: Integer;
  MsgDesc: TCnMsgDesc;
  FChannelReady: Boolean;

  procedure GenerateMsgDesc;
  begin
// 进行具体的组装工作
MsgLen := Size;
if MsgLen > CnMaxMsgLength then
   MsgLen := CnMaxMsgLength;
TagLen := Length(ATag);
if TagLen > CnMaxTagLength then
   TagLen := CnMaxTagLength;

FillChar(MsgDesc, SizeOf(MsgDesc), 0);
MsgDesc.Annex.Level := ALevel;
MsgDesc.Annex.Indent := AIndent;
MsgDesc.Annex.ProcessId := GetCurrentProcessId;
MsgDesc.Annex.ThreadId := ThreadID;
MsgDesc.Annex.MsgType := Ord(AType);
MsgDesc.Annex.TimeStampType := Ord(TimeStampType);

case TimeStampType of
   ttDateTime: MsgDesc.Annex.MsgDateTime := Date + Time;
   ttTickCount: MsgDesc.Annex.MsgTickCount := GetTickCount;
   ttCPUPeriod: MsgDesc.Annex.MsgCPUPeriod := GetCPUPeriod;
else
   MsgDesc.Annex.MsgCPUPeriod := 0; // 设为全 0
end;

// TimeMarkStop 时所耗 CPU 时钟周期数
MsgDesc.Annex.MsgCPInterval := CPUPeriod;

CopyMemory(@(MsgDesc.Annex.Tag), Pointer(ATag), TagLen);
CopyMemory(@(MsgDesc.Msg), Pointer(AMsg), MsgLen);

MsgLen := MsgLen + SizeOf(MsgDesc.Annex) + SizeOf(DWORD);
MsgDesc.Length := MsgLen;
  end;
begin
  if FAutoStart and not FIgnoreViewer and not FViewerAutoStartCalled then
  begin
StartDebugViewer;
FViewerAutoStartCalled := True;
  end;

  Inc(FMessageCount);
  if not CheckEnabled then Exit;
  FChannelReady := FChannel.CheckReady;

  if (not FChannelReady) and (not FDumpToFile) then Exit;

  GenerateMsgDesc;

  if FChannelReady then
  begin
if FChannel.CheckFilterChanged then
   FChannel.RefreshFilter(FFilter);

if CheckFiltered(string(ATag), ALevel, AType) then
   InternalOutput(MsgDesc, MsgLen);
  end;

  // 同时 DumpToFile
  if FDumpToFile and not FIgnoreViewer and (FDumpFile <> nil) then
  begin
if not FAfterFirstWrite then // 第一回写时需要判断是否重写
begin
   if FUseAppend then
      FDumpFile.Seek(0, soFromEnd)
   else
   begin
      FDumpFile.Size := 0;
      FDumpFile.Seek(0, soFromBeginning);
   end;
   FAfterFirstWrite := True; // 后续写就无需判断了
end;

FDumpFile.Write(MsgDesc, MsgLen);
  end;
end;

本来就有输出到文件的功能哇。

Author: jAmEs_ Time: 2009-12-24 16:29

怎么搞？我意思是直接由这个类输出哦，没有查看器的情况下~~麻烦告诉一下，呵呵

Author: jAmEs_ Time: 2009-12-24 16:52

我回去看了一下，好像必须打开查看器，才会输出文件吧？

Author: Passion Time: 2009-12-24 18:02

打开查看器是输出到查看器，然后查看器可以另存文件。
我记得定义DUMP_TO_FILE的编译条件就行了，可以看看CnDebugger.pas头上的编译指令。

Author: jAmEs_ Time: 2009-12-24 23:25

我感觉你忘记了，能否再去看看？DUMP_TO_FILE是启动输出文件，但是如果查看器没有启动，输出时，检查到就会跳出来。
因为输出时，用到MapFile，而MapFile是查看器创建的，没有创建就不会输出了。

Author: Passion Time: 2009-12-25 11:13

你的意思是不要启动查看器而直接输出到文件？

Author: jAmEs_ Time: 2009-12-26 11:15

对啊。。

Author: Passion Time: 2009-12-26 19:39

明白你的需求了。我改了一下，晚上回去提交。

先试一试我改的内容？在附件里。

好像跟我的差不多吧，我加FChannelReady（最好改为ChannelReady...）是为了不多次执行FChannel.CheckReady，因为里面好像有一些代码，避免效能问题，不过有需要我迟点看看。

Author: Passion Time: 2009-12-28 20:19

好的。命名上局部变量似乎是不太合适用F，F都是表示Field，一般是类的成员变量。

Author: jAmEs_ Time: 2009-12-30 10:31

FChannelReady当时是从FChannel.CheckReady变来的，当时忘了删除F

测试OK，你处看看是否需要按我说的用变量来保存FChannel.CheckReady结果，这样可以避免好几次判断。。。

Author: Passion Time: 2009-12-30 17:05

好的，接受。

我处对CnDebug做再次改动，当信息长度大于4096时，自动分割信息，希望接纳。或可考虑增加选项控制。
代码可适当调整。

Author: jAmEs_ Time: 2010-2-26 10:32

没有人回应一下？

新人报到,怎么好像很冷清的。。。。。。
