master..xp cmdshell 执行EXE

[gcaling2006]

我的EXE是DELPHI做的,目的是接收SQL触发器传来的字符串,然后通后消息把字符串传给另一个正在运行的程序,
能找到另一个程序的PID(进程ID),但无法找到另一个在运行程序的窗口句柄.因此就无法接收到消息,

后来想到一个办法,把另一个运行的程序运行时窗体的句柄放在一个INI文件中,这样就不用找这个窗口的句柄了,直接读INI就可得到,但调用SendMessage(winhand, WM_COPYDATA, 1, Integer(@Data));仍不能正常传递消息.

发送消息程序
program send;

{$APPTYPE CONSOLE}

uses
Forms,
windows,
sysutils,
Messages,
WinProcs,
inifiles,
all in 'all.pas';

var
Data: tagCOPYDATASTRUCT;
pBuf: PAnsiChar;
MYHWND: THandle;
inifile: TIniFile;
winhand:integer;
{$R *.res}

begin
Application.Initialize;
Application.MainFormOnTaskbar := True;
Application.Run;

begin
if FileExists(Trim(ExtractFilePath(Application.ExeName)+'com.ini')) = True then
begin
Try
inifile := TIniFile.Create(Trim(ExtractFilePath(Application.ExeName))+'com.ini');
winhand:= strtoint(inifile.ReadString('配置信息','窗口句柄','1'));
Finally
inifile.Free;
end;
end;
GetMem(pBuf, Length(ParamStr(1)) + 1);
try

ZeroMemory(pBuf, Length(ParamStr(1)) + 1);
StrPCopy(pBuf,ParamStr(1));
Data.cbData:= Length(ParamStr(1));
Data.dwData:= Length(ParamStr(1));
Data.lpData:= pBuf;
writeln(ParamStr(1));
SendMessage(winhand, WM_COPYDATA, 1, Integer(@Data));
writeln(winhand);
finally
FreeMem(pBuf);
end;
end;

sleep(3000);
end.

接收消息程序
unit Unit2;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls,inifiles;
const
My_MousL=WM_USER+100;
type
TForm2 = class(TForm)
Label1: TLabel;
procedure FormShow(Sender: TObject);
private
j:integer;
{ Private declarations }
public
procedure Mymessage(var t:TMessage);message WM_COPYDATA;

{ Public declarations }
end;

var
Form2: TForm2;

implementation

{$R *.dfm}

procedure TForm2.FormShow(Sender: TObject);
var inifile:tinifile;
begin
if FileExists(Trim(ExtractFilePath(Application.ExeName)+'com.ini')) = True then
begin
Try
inifile := TIniFile.Create(Trim(ExtractFilePath(Application.ExeName))+'com.ini');
inifile.WriteString('配置信息','窗口句柄',inttostr(findwindow(nil,'form2')));
Finally
inifile.Free;
end;
end
end;

procedure Tform2.Mymessage(var t: TMessage);
var
Data : ^tagCOPYDATASTRUCT;
strMSG: string;
mylen:integer;
begin
Data:= Pointer(t.LParam);
mylen:=integer(data.cbData);
strMSG:= copy(PAnsichar(Data.lpData),1,mylen);

label1.Caption:=strMsg;

end;


end.

用socket通信

[gcaling2006]

SOCKET会占资源吧，不停的等待。

[gcaling2006]

仍然不行,单独运行就可,但用SQL 的XP_CMDSHELL调用,另一应用程序就不能共享数据.见代码 APP1修改数据,APP2接收数据 APP1代码 program send; {$APPTYPE CONSOLE} uses sysutils,forms; {$I DLLDATA.INC} var GlobalData: PGlobalDLLData; procedure GetDLLData(var AGlobalData: PGlobalDLLData); StdCall External 'SHARELIB.DLL'; {$R *.res} begin Application.Initialize; GetDLLData(GlobalData); GlobalData^.S :=ParamStr(1); GlobalData^.I:=12345; Application.Run; sleep(10000); application.Terminate; end. APP2代码 unit MainFrmA2; interface uses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, ExtCtrls, StdCtrls; {$I DLLDATA.INC} type TMainForm = class(TForm) tmTimer: TTimer; lblconid: TLabel; Memo1: TMemo; procedure tmTimerTimer(Sender: TObject); public GlobalData: PGlobalDLLData; end; { Define the DLL's exported procedure } procedure GetDLLData(var AGlobalData: PGlobalDLLData); StdCall External 'SHARELIB.DLL'; var MainForm: TMainForm; implementation {$R *.DFM} procedure TMainForm.tmTimerTimer(Sender: TObject); var sendstr:string; conid:string; begin GetDllData(GlobalData); // Get access to the data { Show the contents of GlobalData's fields.} sendstr := GlobalData^.S; conid := IntToStr(GlobalData^.I); if conid<>lblconid.Caption then begin memo1.Text:='已发送短信'; lblconid.Caption:=conid; end; end; end.

这个得看你运行是否在同一个机器上，同一机器用内存映射，不同的机子用socket通信

[gcaling2006]

用内存映射为什么也不成功呢
