Hi
I am trying to understand
BOOL SetProp( HWND hWnd,
LPCTSTR lpString,
HANDLE hData
);
and
HANDLE GetProp(HWND hWnd,
LPCTSTR lpString
);
functions.MSDN writes:
The GetProp function retrieves a data handle from the property list of the specified window
The SetProp function adds a new entry or changes an existing entry in the property list of the specified window
But what is the meaning of "propery list"?Where is it?Is it WNDCLASSEX's members or something else?
I dont understand the benefits of window properties and window propert list.Please help me.
Thanks...

It's basically a map<LPCTSTR,HANDLE> attached to each window.

Hello,
Edit is derived from class CEdit
int i=0;
vector<Edit*>R;
Edit *p;
p = R[i];
p->SetFocus();
I want to move from one edit box to another which I am able to do.I go from one edit box to another by i++ or i-- depending on the key pressed.and calling the function
R[i]->SetFocus();
But when I click the mouse I am not able to move the focus to the clicked edit box.How should I do it?
In what way should I define a pointer so that I acheive the move ?

Hi All,
Does anyone know of a way to get an abbreviated time zone string? For example getting "PST" instead of "Pacific Standard Time"?
The following function looked promising but it returns the full time zone string regardless of the format:
size_t wcsftime(wchar_t *wcs, size_t maxsize, const wchar_t *format,
const struct tm *timptr);
The msdn documentation says that passing in %z or %Z as the format returns "Time-zone name or abbreviation; no characters if time zone is unknown" but as mentioned it always returns the full string regardless of which I use.
I looked in the registry thinking that each time zone key might possibly contain an abbreviation but found nothing. Here's one key I looked at "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\Pacific Standard Time"
Anyone have any ideas?
Thanks for your help,
Kellie

Parse the full name? Perhaps it is not useful since duplicate abbreviations render them ambiguous.

Thanks Mike, I'm hoping to find something a little more robust but I'll probably end up doing what you mention or making custom registry entries that contain the abbreviations.

I recently upgraded from Microsoft Visual Studio 2003 to 2005, and now my project won't compile, and I have no idea how to fix it.
The code that is broken:
// Copy Constructor
CImageManager(const &CImageManager);
// Assinment Operator
CImageManager operator = (const &CImageManager);
The error I recieve is:
1>c:\programming\programming\programs\calypso\imagemanager.h(44) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
These constructors are declared as private in a class so that only one instance can be created. This is happening with about 12 other files/classes as well.
Please let me know if anyone knows what is wrong with my syntax and why this all of a sudden changed in the new version of visual studio.
Thanks in advance,
Dustin

This worked in VS 2003?
// Copy Constructor
CImageManager(const &CImageManager);
// Assinment Operator
CImageManager operator = (const &CImageManager);
I thought it should be:
// Copy Constructor
CImageManager(const CImageManager &);
// Assinment Operator
CImageManager operator = (const CImageManager &);

Why does Microsoft have to go and fix things so not to allow my bad coding practices.
Yes, I just tried this and it fixes the problem. You are a life saver. If I ever meet you, the beer is on me.

Hello,
CRICH is derived from CRichEditCtrl
int index=0;
vector<crich*>RichEditBox;
CRICH *p = RichEditBox[index];
p->SetFocus();
How do I go to index=1 box in the above example.
p++ will not help as I tried that
Any ideas

p++ won't workout because its not the base address and also 'p' is just a class pointer..which can point to single instance of that class.
use index++ instead of p++

Hello comunity
i use many times in my project "new" to create an object, in my case this is own class derived from
CObject! So, how to cleany the heap properly??
I hope that is my question is easy to understand?! 
What ist different between this two my samples:
CMyClass* pMyClass = new CMyClass();
delete pMyClass;
CMyClass* pMyClass = new CMyClass();
pMyClass = NULL;
delete pMyClass;
thanks in advance
break;

break; wrote:
CMyClass* pMyClass = new CMyClass();
pMyClass = NULL;
delete pMyClass;
This won't work: you will first set the adress to a NULL pointer and then try to free the memory at this adress, which will fail (logical, because the memory at address 0x0000 was not allocated). You should first delete the pointed memory and then set your pointer to NULL to specify that the pointer doesn't point to a valid memory.

Thanks very much!

As a minor technicality, it will WORK, but it won't work as expected. That is, there is nothing syntatically wrong with the code. deleting a null pointer is perfectly valid (and does nothing), but the code will have a memory leak since the memory allocated will never be deallocated.
If you decide to become a software engineer, you are signing up to have a 1/2" piece of silicon tell you exactly how stupid you really are for 8 hours a day, 5 days a week

Yes, that's what I wanted to say. Ok, it wasn't very clear :p. I know that you can delete a NULL pointer but this will simply be ignored (thus leaving a memory leak).

|
|
|

what were you thinking of when you wrote this ?
delete needs an adress to clean !! (the address which new returned when allocated the memory).
if you assign the pointer variable BEFORE deleteing, delete will try to free the memory at address 0 -> bug
but NULLing after the delete is the thing to do...!
