Re: CMap oject copy operation

17-Apr-14 4:58

Hi, is CMap object can be copied to another CMap oject?
I can't find a member function in CMap class.

And if I want to implement deep copy, do I need to loop it , copy every element to another manually?

Why not try it and see what the result is?

What are these files in folders of this os?

17-Apr-14 7:06

As far as I know, CMap has not such a facility. On the other hand, the std::map[^]...

Hi guys
I have OS of the WB150F camera. you can download it here:

https://www.mediafire.com/?jmshouy4c937yw3

I have several question about it:

1- What do these files do?
MakeAv, MakeAvf, sde6 and all files in the "Tools" folder
2- What is the usage of the "brcz.h" file (in this address: \ip\include)?
3- What is the diffrence between the files of "av" folder and "avf" folder in os folder?

Does this have something to do with C++?

Buffer overrun at _CRT_DEBUGGER_HOOK in dbghook.c (using log4cxx)

That sums it up pretty much - The line method executed before is

C++

void Writer::DoWrite(QString auditEntry){
    QByteArray ba = auditEntry.toLatin1();
    char* aestr = ba.data();
    std::string aestdstr(aestr);

    log4cxx::LoggerPtr logger = log4cxx::Logger::getLogger("RMAT");
    LOG4CXX_INFO(logger, aestdstr);//Buffer overrun happens somewhere in this method call
}

I did the search work - Yes, aestdstr is terminated with '\0'. I'm running out of ideas here. The detailed error message is called

Quote:
A buffer overrun has occurred in app.exe which has corrupted the program's internal state. Press Break to debug the program or Continue to terminate the program.

For more details please see Help topic 'How to debug Buffer Overrun Issues'.

Fun fact is that no one has ever seen the help topic 'How to debug Buffer Overrun Issues' (here[^]).
Any thoughts on the issue?

Looking at the documentation for LOG4CXX_INFO[^], I wonder if you should use the char* as the second parameter, like:

C++

    char* aestr = ba.data();
//    std::string aestdstr(aestr);
 
    log4cxx::LoggerPtr logger = log4cxx::Logger::getLogger("RMAT");
    LOG4CXX_INFO(logger, aestr);
}

Thank you kindly for the suggestion, but oddly a missing [static] library on which log4cxx was dependent went missing.
Don't ask me why the Linker didn't complain but the debugger decided to throw a buffer overrun Unsure | :~

This is probably where the buffer overrun was detected, not where it actually occurred. In general it is not possible (or prohibitively expensive) to detect the actual corruption. Try using the Page Heap[^], although this often falls in the prohibitively expensive category. Remember to disable it when you're done!

Creating View without document?

Hi,

Is it possible to create a view (In MFC MDI app)without document as follows?

CMultiDocTemplate* pDocTemplate = new CMultiDocTemplate(IDR_CheckTYPE,
NULL,
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CCheckView));

I mean, passing NULL for the document runtimeclass and use pDocTemplate->CreateNewFrame().

Thanks,
Prasanth

Why you do not want to use the CDocument?

I'd rather be phishing!

What happens when you try it?

Yes, I do it all the time.
- basically, the "View" will not be attached to the derived object class of (CDocument).
- the attached derived (CDocument) object is intended to update the View when the derived object changes.

Outlook Addins Question

I'm doing a project about the Outlook plug-in synchronous address book.
Double-click on the list of email users to add to the recipient email box.
The second double-click on the same email address will lead to repeat.
Now want to read the recipient before double click on the box.But you can't read Cry | :((

C++ Code:

EnumChildWindows(hwndWriteMail, EnumChildProc, (LPARAM)EmailAddr.GetBuffer());

BOOL CALLBACK EnumChildProc(HWND hWnd, LPARAM lParam)
{
int id = -1;
id = ::GetDlgCtrlID(hWnd);
if (id == 0x00001003){
::SendMessage(hWnd, EM_REPLACESEL, NULL, (LPARAM)lParam);
}
return TRUE;
}

Use Windows SPy++ view within the recipient can get RichEdit editbox for the RichEdit normal character but outlook email address will be automatically after formatting is not available

How do I get RichEdit edit box content? thanks

Hi, in my program,I use a CStatic object to flash a string every 3-4 seconds.
But I found, sometimes the string is blinking.

How can I　flash the string and don't have jitter phenomenon?

Define flash and blink. In my book, they are synonymous.

Where are you setting the CStatic object's value at?

I want to show the string like the follow sequence:

0 - 4 Second: Display string
4 - 8 second: Display nothing,clear screen

8 - 12 second: Display string
12-16 second: Display nothing,clear screen
...

Now I found the string blinking during 0-4,8-12 seconds.

It looks your text flickers because you are repeadetly drawing the string. In the 0-4 (and 8-12) interval you have to draw the string just once. You could set a boolean variable the very first time you draw the string and then check it before drawing it again (of course you have to reset the boolean variable upon entering in the 'blank' interval).
