i would like to know how to create
a. Initially the size of the heap is read and an array of that size is created for the heap
b. Another array of size n+1 is created for the handle(key) and it contains impossible values i.e. upto infinity
c. After the first record with name m and priority p is inserted, (m,p) is stored in the heap, and the handle of m is updated to 0.

I'm probably missing a translator plugin...
a. are you talking about a heap data structure ?
b. it's not clear why you need to go to infinity, it's quite a large number, only Chuck Norris can count to infinity.
c. ... why not.

Hiya everyone,
I was searching for some way to find the memory address of a function such as TerminateProcess. Is there a way to do this? I've read something about the VirtualQuery function, but I don't exactly understand how that can be applied. Could anyone give me a few pointers? (and maybe somewhere I can learn some more about windows memory management.)
Thanks. 
EDIT: this is what I'm reading right now.

Something like:
HMODULE hModule = LoadLibrary(_T("kernel32.dll"));
typedef BOOL (*PROC)(HANDLE, UINT);
PROC proc = (PROC) GetProcAddress(hModule, "TerminateProcess");is much less succinct than Stuart's answer.

If you have (for example) TerminateProcess's definition pulled in via a header, then &TerminateProcess is sufficient...

Thanks (to both you and DavidCrow, but I can't reply to two threads with a single reply...), I'll try that. Can't believe I didn't think of that... 
EDIT: Okay. So now if I hook TerminateProcess with my own dll, shouldn't the value of &TerminateProcess differ from the address of TerminateProcess in the kernel32.dll? I don't see any difference in the two addresses right now..

You can make a reply pointing to the other one's address... (sorry for the bad pun)

Hi All vc++ Masters,
I am migrating my vs-2003 code to vs-2008(on vista machine)...I have the compilation successfully.But i am getting the compilation errors in the debug mode...
I think It should be issue of multiple string datatypes in my project like: MFC Cstring, DblString datatype, char *. It might be mismatch of MFC/ATL Cstring datatype in old and new MFC library....The error is like this...
fwpipd.lib(fwstsrv.obj) : error LNK2019: unresolved external symbol "public: int __thiscall
DomIssuerInfo::HasSurIFeeBillableDebt(class DblDateTime const &,class ATL::CStringT<char,class StrTraitMFC_DLL<char,class ATL::ChTraitsCRT<char> > > const & )
My related function is like this in the code:
BOOL DomIssuerInfo::HasSurvFeeBillableDebt(const DblDateTime& dtReference, const CString& csRatgQualCd )
Can anyone suggest to resolve this error,please....
Thanks in Advance.....

Compare the project's Release vs. Debug settings.

Could someone with experience on this subject point me to sample code or article describing how to communicate between splitter panes in the same frame?
I did few searches and cannot find this subject covered in any useful detail.
I have posted message in left pane and can process it using WindowProc ( in same class).
I am using Spy and do not see how the WM_USER message got there.
I could just keep at it until I find the message-processing path by trial and error.
Any constructive help would be appreciated to speed up this process.

If you're using SDI or MDI, this sort of communication is already setup for you using the MVC or observer pattern.
From one view you call CDocument::UpdateAllViews[^]. This function will call each view's OnUpdate[^] member function to notify of the changes.
The documentation explains more about it.

I have been using UpdateAllViews (with parameters) to add new view to doc / view, no problem here.
However, I run into assertion problem when trying to RemoveView using UpdateAllViews for now obvious reason ( after few frustrating hours of “coding”) - MFC is trying to update deleted view(s). Now I am using RemoveView in CSplitterWnd and after I figure out how to repaint the splitter pane after views removals I’ll be OK.
There is small catch here - the RemoveView literary removes the whole pane - including the background ( no surprise here) therefore one must CreateView immediately.
Thanks for your help.

If you're making a change to something both views will see, then you should be making that change in the document, and use UpdateAllViews to "tell" the views that something has changed and they should do something about it.
If you're adding / removing views, then neither the view(s) or the document are the right place to do that. I'd suggest the frame holding the views, either the CChildFrame or CMainFrame (for SDI) would be the right place to handle any "add a new view", "kill a view", "change a view" message.
UpdateAllViews is *not* the place to be murdering Views in their sleep.
I hope that helps,
Iain.

Hi
a quick question
if I allocate a cdialog derived object via
the new operator
just so I can save data in the object
that won't associate with windows resource
until I do the create specfing the dialog item
from the resource file
after the create. The framework should call
my ::initdialog overideable
sounds right ??
Btw in the create is where I would specify
the dialog item resource

Just for the sake of saving data, why would you want to do this?

Wouldn't it be easier to just code it up and see (when OnInitDialog() is called)?

I have two threads providing information
for the dialog
which ever finishes first I'll save that info
in a Cstring member of the CDialog derived
object
When the second thread finishes and I'am
ready to display the Cdialog I'll do the
Create to get things going
Thank

Ok, but why use a heap-based CDialog object?

Since I need this storage while the Cdialog
exists it seems like a good place to save the
Data
|

Saving the data in the dialog object is fine. I'm just curious why you think it needs to be heap-based. Are you creating it in one place and then doing the thread-related code elsewhere?

I just if I Created it on the I guess stack
e.g. Cdialog mydialog then
1) I would have to pass the Cdialog constructed
paramters such as the dialog resource item
to initialize the windows object
2) the CDialog objects would be lost between
the windows/framwork messages
waiting for the second thread to complete
with the rest of the data
thankx
