Sorry i tried this as follows
ON_NOTIFY_REFLECT(UDN_DELTAPOS,OnSpinContol)
Its throws syntax error and could not find any sample in google to declare the message.
|
|
|
|
|
In what class did you implement it?
Please, post the exact code snippets!
|
|
|
|
|
BEGIN_MESSAGE_MAP(CMyClass, CScrollView)
ON_NOTIFY_REFLECT(UDN_DELTAPOS,OnSpinContol)
END_MESSAGE_MAP()
void CMyClass::OnSpinContol(NMHDR *pNMHDR, LRESULT *pResult)
{
}
|
|
|
|
|
CMyClass seems to be a parent/owner of the spin control. So there must be ON_NOTIFY macro, not a ON_NOTIFY_REFLECT
|
|
|
|
|
That is for handling the message by the control class itself when having it derived.
To handle the message in the parent do it like you have done already:
ON_NOTIFY(UDN_DELTAPOS, IDC_SPIN1, OnDeltaPos)
|
|
|
|
|
Even tried below one, but no luck. 
BEGIN_MESSAGE_MAP(CMyClass, CScrollView)
ON_NOTIFY(UDN_DELTAPOS, IDC_SPIN, OnSpinContol)
END_MESSAGE_MAP()
void CMyClass::OnSpinContol(NMHDR *pNMHDR, LRESULT *pResult)
{
}

1. Define "no luck".
2. Do you pass the correct control ID (IDC_SPIN)?

Hey Thanks Victor. Its working now.
|
|
|
|
|
It is very probably sourced by the creation of your spin control:
m_spin.Create(UDS_HORZ, CRect(0, 0, 50, 50), this, 1011);
That misses the common window style flags like WS_CHILD | WS_VISIBLE | WS_TABSTOP.
Just out of interest:
Why are you creating your controls manually instead of using resource templates?
With templates the default settings are initially set in the resource editor so that such errors did not occur.

|
|
Hey Thanks..
Finally its working. The very first thing is i am new to MFC and second is i am creating all dynamic windows and controls based on user input.

I AM TRYING TO READ ARABIC QR CODE I HAVE GOT STRING LIKE THIS:
"0E" & ChrW(2) & "!پù;ر-ً" & ChrW(5) & "üà1" & ChrW(18) & "ثV½›H$»سè" & vbBack & "“أK»V¢®؛" & ChrW(21) & "*" & ChrW(2) & " |" & ChrW(26) & "M§" & ChrW(18) & "uس/ءd'ق" & ChrW(15) & "•qw}َ" & ChrW(22) & "î" & ChrW(31) & "ِه" & ChrW(30) & ">›جWگ¢Kh" & vbCr
IF YOU PLEASE I WANT TO CONVERT IT TO REAL STRING
THANK YOU
|
|
|
|
|
That looks like Basic code, not C/C+.
|
|
|
|
|
YES IT IS VISUAL BASIC BUT IS THERE ANY WAY TO UNDERSTAND THAT CODE
|
|
|
|
|
Yes read up on Visual Basic or go to a Visual Basic forum and ask.

Text in Arabic would either be written in Unicode, or using an Arabic "code page" (a throwback to the days when characters were 8 bits, and so your program had to "know" what language was encoded in codes 128..255). One way to encode Unicode in QR codes is using UTF-8. Have you tried running the raw QR data through a UTF-8 decoder?
Note that if the raw QR data does not start with a BOM (Byte-order mark), you will have to try both low-endian and high-endian versions.
Ad astra - both ways!

It's Visual basic you are on a C/C++ forum it all reads like Arabic to me including the code, go to a Visual Basic forum.
All I get is clearly text isn't in the right format or your code is wrong which I feel pretty confident you already worked out.
So how do expect me to fix it, I can't even understand the code.
In vino veritas

- Check the encoding of your QR data. Are there extra (non-Arabic) bytes, or anything else?
- The data that you are receiving from the serial port is 8-bit bytes. It must somehow be converted to Unicode characters, according to the encoding determined in stage (1).
And lastly:
- Move this question over to the Visual Basic forum. People there may be better able to help you with your code.

Hi,
Am trying to connect WinTECH OPC Client to MaxDNA V6.0.7 server in local PC and LAN network also. These Connection was successfully established but it was showed "Tag Quality bad" and "Value Unspecified Error".
How to solve this issue please help me ASAP.

What does it have to do with C/C++/MFC programming?
Did you write some code that caused this error?
|
|
|
|
|

I'm attempting to port some old code from VS2005 C++ to VS2017. One problem that I don't know how to address is how to convert the old _beginthreadex to what would be the correct call in 2017.
VS2005 code is calling a member function that is in a class:
m_sendThread = (HANDLE)_beginthreadex(NULL, 0, sendData, this, 0, &this->m_sendThreadId);
I've casted it it to: m_sendThread = (HANDLE)_beginthreadex(NULL, 0, (unsigned(__stdcall *)(void *))sendData, this, 0, &this->m_sendThreadId);
Code compiles but will exit with code 1073741855.
The class is a class that handles winsock connections and sendData is called to start the thread once the socket has been established.
I am new to classes and even newer to threaded programs so it is hard for me to say how to fix this problem.
Any help would be much appreciated.
Thanks.

The _beginthreadex() version used by your code has not changed since VC 6.0 besides the return type:
VS6: _beginthread, _beginthreadex[^]:
unsigned long _beginthreadex( void *security, unsigned stack_size, unsigned ( __stdcall *start_address )( void * ), void *arglist, unsigned initflag, unsigned *thrdaddr );
_beginthread, _beginthreadex | Microsoft Docs[^]:
uintptr_t _beginthreadex(
void *security,
unsigned stack_size,
unsigned ( __stdcall *start_address )( void * ),
void *arglist,
unsigned initflag,
unsigned *thrdaddr
);
If you need to cast the start_address parameter (your sendData function) to avoid compilation errors, you should change the function declaration instead. Never use casting for such (address of function) parameters but provide correct types.
An exit code of 1073741855 (0X4000001F) is not a standard error code. You might use the debugger to find out when and under which conditions your application exits with that code.
I guess that the problem is not related to _beginthreadex() but to the thread function itself or even any other parts of your application.
