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

radus21515-Apr-09 1:14

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.

That's true. When your application gets terminated, you really don't have to worry about the memory it was using. All those get wiped off.

First of all, why are you writing such a rogue program that would do nothing good but allocate huge amounts of physical memory? Tell me the name of your program. I must be sure never to use it!

Vista.

Well...No, I'm wrong Vista uses all that memory in order to prevent you to access system's resources... Roll eyes | :rolleyes:

Actually, in this case, I would like to defend Vista. It just tries and fills up available physical memory with programs that you consecutively use (XP does not do that, so there's plenty of free available memory shown up in the task manager) so that the next time you open the program, it is opened fast. A pretty good idea if you ask me. Smile | :)
