At first glance, that article seems to be more geared towards rubber banding a selection. While Ctrl+Click may work, too, there may be extra code there that is messing you up. Perhaps you could use Paul DiLascia'c code from here, or a related article (alas with more features) from here.

I tried the code from the second link. It behaves the same as the code from Syed Babu from codeproject. If I select multiple items using Ctrl and left mouse button it selects JUST THE LAST 2 previously selected items; the first item selected in a row of three is always deselected. I don't get it, I have the same code as the original code. There's something strange here.

The code looks fine actually. Can you elaborate the problem you are facing in this code?

The code I'm refering to is from here: http://www.codeguru.com/cpp/controls/treeview/misc-advanced/article.php/c723/Allowing-multiple-selection.htm[^]

There's not much to elaborate. I just took this code, all these functions, and put them in my CTreeCtrlXML class which is derived from CTreeCtrl. And I have the problem I wrote above.
I have the same exact problem by using the Syed Babu code from here: MultiSelection Tree Control[^]

I cannot attach the two projects here. I don't see any attach button. Can I send you on a private mail the two projects and have a quick look, please?

How to write registry after log in windows with mfc?

Dear all:

I implement a application, when I log in windows, the application will auto

start, and write registry in HKEY_CURRENT_USER,

SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run.

The context of registry is a wav file path.

I put the wav file and the application in the same folder.

My code show as below:

C++

HKEY hKey = HKEY_CURRENT_USER;

TCHAR filePath[MAX_PATH];
TCHAR dirPath[MAX_PATH];

GetCurrentDirectory(MAX_PATH, dirPath);

StringTruncate(filePath, dirPath, "\\Default.wav");

//For ex: filePath may equal C:\abc\123\Default.wav, if my folder path
//is C:\abc\123.

WriteReg(hKey, _T("SOFTWARE\\Microsoft\\Windows\\CurrentVersion"), _T("Sound"), filePath);

My question is:

when I log in windows, the registry value always equal to C:\Windows\system32\Default.wav, Not my folder path.

How can I write the right wav file path after windows log in?

Thanks for your help, Victor.

Did you check that writing to the registry was successful?

Dear Jochen:

I use the same code, but different condition.

condition 1: windows run stable, it write the registry success with my folder.

condition 2: after log in windows, it write the C:\Windows\system32 path.

Thanks for your help, Victor.

What is the value of filePath at the time of writing? Hint: it's not what you think it is.

Dear David:

I know the filePath equal to C:\Windows\system32.

The value of registry which I write is different between log in windows and run windows stable.

How can I write the same value in log in windows?

So then why continue to use it?

Which has nothing to do with anything.

Why not just use:

TCHAR filePath[MAX_PATH] = _T("C:\\abc\\123\\Default.wav");
WriteReg(hKey, _T("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run"), _T("Sound"), filePath);

All that said, I suspect you are wanting to use ::GetModuleFileName(NULL, ...) instead.

It is right, Firstly, you should use ::GetModuleFileName(NULL, ...) to get the path of your application image,
and then, get what you want by this path.
If you set the path as const value, it's not convenient!

CMap oject copy operation

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?

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?

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

Dropkicked Murphy16-Apr-14 2:59

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 | :~
