线程添加TNMUDP问题

[shuqian526]

Background_Process.h中
class Background_Process : public TThread
{
private:
public:
TNMUDP *UDP1;
}

cpp中
__fastcall Background_Process::Background_Process(bool CreateSuspended)
: TThread(CreateSuspended)
{
UDP1= new TNMDUP(this);//无法通过
}


[C++ Error] Background_Process.cpp(40): E2303 Type name expected
[C++ Error] Background_Process.cpp(40): E2034 Cannot convert 'int *' to 'TNMUDP *'
[C++ Error] Background_Process.cpp(40): E2379 Statement missing ;

这是为啥，我看delphi中，，UDP1 := TNMDUP.Create(Self); 就能过？！！百思不得其解

[周药师]

TNMUDP *UDP1;

UDP1= new TNMDUP(this);//无法通过
见红色部分 是你输入错误 应该是TNMUDP(this)

。。。。咕~~(╯﹏╰)b，，拷贝糊涂了,另指针为空
UDP1= new TNMDUDP(NULL);

继续调试，，成功会，我把代码贴出来，

[shuqian526]

class Background_Process : public TThread
{
private:

TNMUDP *UDP1;
void __fastcall MyUDPDataReceived(TComponent *Sender,int NumberBytes, AnsiString FromIP, int Port);
}

.cpp
__fastcall Background_Process::Background_Process(bool CreateSuspended)
: TThread(CreateSuspended)
{
UDP1= new TNMUDP(NULL);
UDP1->LocalPort = 6004;
UDP1->OnDataReceived = MyUDPDataReceived;
}

///
void __fastcall Background_Process::MyUDPDataReceived(TComponent *Sender,int NumberBytes, AnsiString FromIP, int Port)
{
///your code
}
