Hi, I have a multithread problem like the following lines, when I compile
this code I caught a "error C2665", the error description is : none of the
number1 overloads can convert parameter number2 from type 'type'
//-----------------------------
UINT ReadDatFile(int i_thread)
{
AfxMessageBox(i _thread);
return 0;
}
// CReadDatFilesVi ew ÏûÏ¢´¦Àí³ÌÐò
void CReadDatFilesVi ew::OnBnClicked Readfile()
{
// TODO: ÔÚ´ËÌí¼Ó¿Ø¼þꬅ ª´¦Àí³ÌÐò´úÂë
UpdateData();
int i_threadnum;
for(i_threadnum =1;i_threadnum< =m_maxthreadnum ;i_threadnum++)
{
AfxBeginThread( ReadDatFile(i_t hreadnum),GetSa feHwnd(),THREAD _PRIORITY_NORMA L);
}
}
//------------------------------
Could anybody tell me why? Thanks in advance!

First of all, when posting questions like this, you should identify the
exact line that triggers the error, and the complete error message.
Otherwise we have to read through all of the code, trying to figure out
which line it might be.

This is not the correct function signature for a thread function.
Check MSDN.

}
You supply the wrong arguments.
The first parameter should be the function pointer only.
You try to supply a function pointer together with the function argument.
If your function has the correct signature, it will receive the 2nd
parameter of AfxBeginThread as a parameter when it is executed.
Read the documentation for AfxBeginThread for more information.

I don't know if this is possible but what I would really like to do is
to use On Error Goto to capture the code that is being executed when
an error occurs.
Any help would be much appreciated.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
