Assuming that the program is reading from standard input, you'd have:

hi,
I have a question about threads. In the following code you can see a class which creates a thread, taking a callback fn that gets called repeatedly (it's using boost, but the concepts I'm trying to understand aren't boost specific, maybe?). A second file instanciates that class, using a local fn for the callback;
mythreadstuff.h
-----------------------------------
typedef boost::function1<void, int> CallbackFn;
void MyThread(CallbackFn fn)
{
int a = 0;
do {
(*fn)(a++);
Sleep(1);
} while (1);
}
class Caller {
public:
Caller(CallbackFn fn) : m_callback(fn) {}
void Start() {
m_thread = new boost::thread(
boost::bind(&MyThread, m_callback)); }
CallbackFn m_callback;
boost::thread* m_thread;
};
-----------------------------------
mymainstuff.cpp
-----------------------------------
#include "mythreadstuff.h"
void showVal(int a)
{
// do something with a
}
void main()
{
CallbackFn fn = &showVal;
Caller mycaller(fn);
mycaller.Start();
Sleep(1000);
}
-----------------------------------
when showVal is called and does its thing on 'a', is it in the parent process from the main() process, or is it in the child thread process? Do I need to protect what's going on in there with mutexes, or is that only if the function shares some global variable in mymainstuff.cpp?
Is there a way of printing a process id (or some other identifier) which shows what process showVal is acting in?
thanks,
nik

Yes, it runs within the thread.
If you're in Visual Studio, you can break within your thread on the (*fn)(a++);. Use F11 to step into the function. Then select Debug->Threads from the main menu, and you'll see a list of running threads, with the current thread highlighted.
I'm not sure how many threads you'll see there (depends on your application), but if you double-click any of them, it'll open an appropriate window to display the code currently being executed in that thread. With Call Stack in place, you'll see that one of those threads has your main() happily sleeping while your thread is executing the callback.

Local Machine: Windows Xp
& it seemed problem happened when it runs to these code:
<br />
CADOParameter pParamIn_Readnum(CADORecordset::typeInteger, sizeof(int));<br />
pParamIn_Readnum.SetValue(pMydoc->rwbossdlg.m_nReadNum);<br />
CADOCommand pCmd(pAdoDb_RB, "ydcj_getdata_574");<br />
pCmd.AddParameter(&pParamIn_Readnum);<br />
pRs_RB = new CADORecordset(pAdoDb_RB);<br />
pRs_RB->Execute(&pCmd));<br />
Thx!

I want to write a utility to turn off the Direct3D and DirectDraw function.
I can turn off the function by the following procedure :
a. Open "Run" in "Start" menu and type "Dxdiag".
b. Select "Display" tab, and click the "Disable" button with "Direct3D Acceleration"
But I can't find solution that uses Windows API or other way.
Could someone help me to find out how to implement this function?
Thanks!

i use CreateWindowsEx to create a listbox and make its single item selected by code, i don't want the user to change the selected item index. i tried EnableWindow to disable the listbox window but it disabled the scrollbar of the listbox as well. What API should i use to make the listbox viewable only? which message should i process to prevent users from selecting another item in the listbox? (API solution only!)

Put your load image code in InitDialog (LoadBitmap, LoadImage etc) but process drawing in OnPaint (BitBlt, ..strecht...etc).
