线程中通迅有两处错误，如何修改？

[flyskytoday]

主要是线程间的通迅，检测
程序是七拼八凑的，这样能否实现还是未知
请大家帮我看下现在的错误，谢谢

第一处 : error C2440: 'type cast' : cannot convert from 'class CString' to 'long'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
第二处 : error C2664: 'send' : cannot convert parameter 2 from 'long' to 'const char *'
Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast

1、类型不对
2、注意变量的作用域

char* pbuf = new char[SendData.GetLength];
strcpy(pbuf, SendData);
PostThreadMessage(ThreadID,WM_USERMSG,0,(LPARAM)pbuf); //第一处错




if(0 > send(sockClient,(const char*)msg.lParam,strlen(msg.lParam)+1,0))//第二处错
{
Sleep(10);
send(sockClient,(const char*)msg.lParam,strlen(msg.lParam)+1,0);
delete[] msg.lParam;
}

1.(long)((LPCTSTR)SendData)
2.(const char*)msg.lParam

没仔细看代码 只针对你这两个错误来说
PostThreadMessage(ThreadID,WM_USERMSG,0,(LPARAM)SendData); //第一处错
修改为
PostThreadMessage(ThreadID,WM_USERMSG,0,(LPARAM)&SendData); //这里应该传地址


send(sockClient,msg.lParam,strlen(msg.lParam)+1,0))//第二处错
修改为
CString *pStr = (CString*)msg.lParam;
send(sockClient, pStr->GetBuffer(0) , pStr->GetLength(), 0)) //send的第二个参数是字符指针
pStr->ReleaseBuffer();

错误信息都有提示，都需要你做类型转换等，填好对应的参数类型
