Can we get a handle or icon id of an item which has been inserted in to a ListCtrl?
Example: if we have two icons in our image list and we inserted 100 items in the list can we find out if item 30 has icon #1 displayed with it or icon #2 displayed with it
P.S we are assuming that a image list has been associated to the control.

If you're using MFC, do this:
LVITEM lvi;
lvi.mask = LVIF_IMAGE;
lvi.iItem = nItemIndex;
m_listCtrl.GetItem(&lvi);
If you're not using MFC, do it this way:
LVITEM lvi;
lvi.mask = LVIF_IMAGE;
lvi.iItem = nItemIndex;
SendMessage(hwndListCtrl, LVM_GETITEM, 0, (LPARAM)&lvi);
Hope this helps,
Ryan

I create a dialog.
And it is not expected to be closed when pressing the "Esc" key.
How to solve this problem?
Thank you in advance

Try to override CDialog::OnCancel().
Something like
void CMyDialog::OnCancel() { return;}

It works well after I do as your directions.

I am glad that it works well. I would also consider kmaz's directions as well even though I have never tried (or for that matter of fact heard that approach [then again, I have a lot to learn]). But it sounds very interesting and probably is worth to try it.

It seems very difficult
If by overriding the function, I want to do like below:
bool m_bEsc;
void CAbc::OnCancel()
{
if( !m_bEsc)
return;
else
CDialog::OnCancel();
}
bool A()//Some operations to keybord's actions
{
....
}
Do you think that can work well?

I don't see a reason why that would not work. Somebody else correct me please if I am wrong. But you have to try it yourself.

I would create an accelorator, which would disable the esc key and let you give other key combos functions.
|
|
|
|
|
I am sorry
I don't understand "and let you give other key combos functions"
What's that meaning?
Can you tell me?

He means that using an accelerator, you can make other key-combinations perform other operations, as well as preventing the dialog from closing. However, Toni78's solution is the best and easiest one.

In the psapi.lib, the function getProcessMemoryInfo() returns a PROCESS_MEMORY_COUNTERS struct.I urgently want to know whether PROCESS_MEMORY_COUNTERS.WorkingSetSize can directly indicate the size of memory a process currently occupies.If it can, the value returned is KB,OR B? If it cannot, how can I get the size of memory a process currently occupies?
I am in emergency and long for any help!Thanks!

WorkingSetSize should be the size of the process that is loaded in RAM in bytes.

I want to add a bitmap as a background to the main Window of SDI document. Can anybody help me what to do? I am really in emergency. I will really appreciate help.

Draw the bitmap first in your OnDraw method of your view. Then, draw the rest of your view. You may have to pDC->SetBkMode(TRANSPARENT) to prevent your drawing from hiding the bitmap.
onwards and upwards...

Can u please provide me the code . I am really not an expert in VC++. That will be really helpful.

I'm trying to make a Help app that is linked to an already funtioning C++ program. The problem I seem to have is that if I change the text of AfxCore.rtf it has an error pop-up when I load the workspace. I have no experience with making a Help app and I'm the one assigned to figure it out. I'f anybody knows what goes on in MSVC++ when it comes to making a Help app, then please help me. The MSDN tutorial is horrid, I can't make heads or tails of it.

Have a look at this website [^] and if that doesn't help, run a search on google on help file tutorials. That's how I learned how to write help file. Hopefully, it will work for you too. It is not difficult at all. You just have to learn what kind of symbols to insert when you create footnotes.
I have a few tutorials and if you can't find anything, give me your email address and I will email them to you. But I have to go through my CDs and find them first.

I am reading "Windows Graphics Programming", by Feng Yuan, and in the beginning he writes his own custom Window class to demonstrate a number of code techniques. It's C++, and looks a lot like the classic style of Petzold (I'm sure many of you are familiar with Petzold). Anyway, he writes two Windows Procedures for his class, one virtual and one static, (this is kind of confusing) so that the Windows system will dispatch messages to the correct message handler (he subclasses his child windows from this class).
Anyway, forget all that, my question is about something else entirely. In his header file for this custom window class, he lists the usual function calls you would make: the two Windows Procedures, constructor(void), destructor, Create, RegisterClass, and sets up the default message loop. Then, and this is what I don't understand, he does this:
BOOL ShowWindow(int nCmdShow) const<br />
{<br />
return ::ShowWindow(m_hWnd, nCmdShow); <br />
}<br />
<br />
BOOL UpdateWindow(void) const<br />
{ <br />
return ::UpdateWindow(m_hWnd);<br />
}<br />
What exactly do those return statements do?
Oh, sorry, m_hWnd is the handle to the Window(type HWND). In his constructor, he does this:
KWindow(void)
{<br />
m_hWnd = NULL; <br />
}
