Hi All,
I have problem with my project linking. Frown | :(

It fails and the errors are
error LNK2001: unresolved external symbol __RTC_Shutdown
error LNK2001: unresolved external symbol __RTC_InitBase
error LNK2001: unresolved external symbol "__declspec(dllimport) public: __thiscall std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >(char const *)" (__imp_??0?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@QAE@PBD@Z)
error LNK2001: unresolved external symbol ___security_cookie
and a lot such us.

Can anybody tell me what can be the reason?

Not linking with the correct library, perhaps?

The strange part of this is that i could build the sources before installing the oldest version of WinDDK. And i have never changed any lib files that are linked to my project.
Thanks anyway.

Looks like you're linking against the wrong C/C++ run-time libraries. Check that the correct Visual Studio directories are in the VC++ library path (Tools->Options->Projects and Solutions->VC++ Directories and select 'Library files' for the 'Show directories for:' combobox).

Hi all,

I have a customized ListCtrl, and Called SetTimer() but OnTimer() handler will execute only once..

And I does not called any KillTimer(),

My OnTimer is Like this

<br />
void ListCtrlEx::OnTimer( UINT nIDEvent_i )<br />
{<br />
    if( 100 == nIDEvent_i )<br />
    {<br />
        // Do some thing<br />
    }<br />
    CListCtrl::OnTimer( nIDEvent_i );<br />
}<br />
<br />
// My set timer is in MouseMove<br />
// If mouse butto is pressed<br />
SetTimer( 100, 300, 0 );<br />

Any possible reason for the same

Regards,
Radhakrishnan G.

Don't called default OnTimer of CListCtrl, for your timer ID.

void ListCtrlEx::OnTimer( UINT nIDEvent_i )
{
if( 100 == nIDEvent_i )
{
// Do some thing
}
else
{
CListCtrl::OnTimer( nIDEvent_i );
}
}

I am using MFC Treeview control in my application. For each tree node has some images. usually the image is left side of the tree node but i would like to add this image after the text of the node.
Can you please suggest some ways to do this?

Thanks in advance.

You will probably need to have to handle NM_CUSTOMDRAW and do the drawing yourself.

I suspect you'll need to resort to custom drawing. Here's a page[^] describing how custom draw works for tree controls.

And here's just one example of a CP article that uses custom-draw with a tree control[^].

Windows console application freeing up RAM memory

hi everybody!
I am writing Windows console application with Microsoft Visual Studio 2008 (using C only) which needs to allocate big amounts of RAM memory with malloc() anc calloc(). The execution of program can be stopped anytime by user pressing CTRL+C keys or by shutting down console window.
What happens to previously allocated memory when it happens? Is it freed up by the system automatically (I guess not?) or do I need to keep track of allocated memory blocks and free() them all myself when the application receives close signal? If this is the case can anybody direct me to any C code solving this problem?

Thank you in advance,Radek

According my knowledge, windows os will do remaining job mean os will free all memory which allocated by process when process got exited.

You need to free memory that you used(of course if your language was C# you didnt need to do it because it frees memory auomaticaly).

Because the there's a thing called Garbage collector[^], which automatically takes care of all memory de-allocations in case of C# or any other CLI languages.

I am not clear about C# but as per your answer is it same like JVM used in java? Which take care about memory management.

No, in Java it is also called the garbage collector. I guess you are a bit confused about the names. JVM stands for Java Virtual Machine.

Yes it is garbage collector. But it is part of JVM. Because at compile time java compiler not going to put code related to garbage collection.
