(VC/MFC) passing parameters to a thread through a struct

The following reprint "Gu su old poplar": http://www.cnblogs.com/fdyang/archive/2012/06/15/2858730.html

Pass parameters to the thread through the struct.

Purpose: in a dialog box, click the button to start multiple threads calling external programs (batch), get the return value, and then update the results to multiple edit controls

idea: control data updates in the thread function by passing parameters to the threads through a struct that contains control information.

steps:

1. Create a struct in the header file XXXDlg.h of the dialog class, including a pointer to the control.
struct threadinfo{CEdit *pedit1_1; }

Next, declare the thread function: UINT threadfunc (LPVOID lpparam);

Note that both of the above should be outside the class Cxxxdlg.

2. Define public variables in the XXXDlg.cpp file: (global variable)
Threadinfo Mthreadinfo;

 
3. In the message handler function of the button, create the thread, calling the thread function. (1) Set the value of the instance of Threadinfo .   mthreadinfo.pedit1_1=&edit1_1;   //point to edit control      //(2) Start a thread    cwinthread *pthread=afxbeginthread (    threadFunc,     &mThreadInfo,    THREAD_PRIORITY_NORMAL,    0,     create_suspended  );   pthread->resumethread ();     //(3) Add a threading function outside the class    Uint threadfunc (lpvoid lpparam)    {    threadinfo *pinfo= ( threadinfo*) lpparam;     //A pointer to an instance of the struct body.     //calls the batch handler function and displays the returned result (CString) to the edit  control.     pinfo->pedit1_1->setwindowtext (Docheck (Batfilepath));    return 0;   }
