return TRUE;
case WM_COMMAND:
switch (LOWORD(wParam))
{
case ID_BTN_START:
hPgb=GetDlgItem(hDlg,ID_PGB_MAIN);
[COLOR=Red] SendMessage(hPgb,PBM_SETRANGE32,0,100);
SendMessage(hPgb,PBM_SETPOS,10,0); //这里能正常显示进度[/COLOR]
hThread=CreateThread(NULL,0,&ThreadProc,&hPgb,0,&ThreadId);
return TRUE;
}
break;
case WM_CLOSE:
EndDialog(hDlg, 0);
return TRUE;
}
return FALSE;
}
static DWORD WINAPI ThreadDownLoad (PVOID pParam)
{
[COLOR=Red] SendMessage(pParam,PBM_SETPOS,60,0); //这里没作用[/COLOR]
return 0;
}
偶需要在线程中控制一个进度条，写了上面的程序，红色部分在主线程中没问题，但是在子线程中就不起作用，搞半天没发现原因，特来请教。
谢谢先，在线等了。
