IMHO, there is something wrong with your design. The list control should be used only to display information, not to store it. Typically the data is stored somewhere in your document class (in case you are doing a SDI application) and is only displayed in the list control.
So if you want to save it, you don't interract with the list control.
If possible, try to separate the 'logic' and data storing from the way it is displayed.

BTW, if you need to insert so much data in your list control, it will probably be quite slow. I think (I'm not sure because I don't use this control a lot) that you can use a virtual mode. Instead of putting all your data into the control, you let the control ask your program what to display. In this way, only what is currently visible will be 'asked' by the control which should be faster.

You can use of a thread or timer for read and insert values to listctrl and you can use of CFile for save these values.

Some Windows filestore-explorer-type folders have on their left edges a displayed tree of folder and file names. The nodes of this tree can be collapsed and expanded by clicking on the node points.
Please, is there a function that I can call to make such a tree (not necessarily of folders and files) appear in a Windows program that I write?

MFC enabled developer? Go through CTreeCtrl class [^].
No MFC? Use Tree View API [^].

You want to use of CTreeCtrl,and if you search on the codeproject you can find customize treectrl.

Hi all,
In Visual Studio 2005, from one method in dll, I'd like to search the way how to find out the name of dll where this method is.
e.g.
TEST.dll
In TEST.dll, I've some methods like method1
and from method1, how can I find out the name "TEST.dll"
Many thanks in advance
Hope to hear the help soon.

Hello everyone,
Reading from book Windows Internals, we should use private bytes to monitor memory leak.
1. I think the reason why not using virtual bytes, is because there may be some shared materials counted as a part of virtual bytes -- like shared library and file map;
2. I think the reason why not using working set, is because sometimes working set is trimmed and sometimes not all committed virtual bytes are in working set -- like demand for zero scenario.
Are my understanding for (1) and (2) correct?
thanks in advance,
George

By chance have you asked either Dr. Russinovich or Mr. Solomon if your understanding of their book is correct?

Thanks DavidCrow,
I have read the section of memory management, and it is only mentioned using private byte to monitor memory leak is correct. I want to do further analysis why using other parameters, like virtual bytes and working set to monitor memory leak is not correct to verify we truly understand the points of memory management.
It is appreciated if you could share your points.
have a good weekend,
George

Now do you check private bytes for monitor emmory leak what was result?
|
|

|

Thanks Hamid,
In my limited testing, private bytes keep increasing if there is memory leak, but I am not sure whether the general rule applies for all scenarios. It is appreciated if you could share some of your points.

George

Do you want to find memory leak of your program or all programs?
|
|
|
|
|
Only my program is ok, Hamid!
Any ideas?

About how to detect memory leak?

Thanks Hamid,
This link only describes how to use general process to detect and fix memory leak. My question is whether it is correct to watch private bytes, working set or virtual bytes counter.

George

Did you use of CMemoryState for memory leak ?
|
|
|
|
|
No, Hamid. I am not using it since it is MFC stuff.
My original question is about how to use memory counter to monitor memory leak.

George

dear all
how to solve the following problem..thanks a lot..
for (int k = 0; k< 150; k++)
{
if (d[k] == c[k][0])
{
sum1 = c[k][0];
sum1 = sum1 + 1;
num1 = num1 + 1;
}
why sum1 can't accumulate..it always showed me 1 + the previous value...

Probably (my CPMRU suggested) you want to do the following
for (int k = 0; k< 150; k++)
{
if (d[k] == c[k][0])
{
sum1 = c[k][0];
}
sum1 = sum1 + 1;
num1 = num1 + 1;
}
or something similar... Maybe posting your requirement will help.
