in addition, such a constness concerning a member function is allowed to modify a data member if and only if it was declared mutable.

class sample
{
CString s1;
mutable CString s2;
public:
CString GetItemText(int nRow, int nCol) const;
};
CString sample::GetItemTextint nRow, int nCol) const;
{
s1 = _T("abc");//error because an const function can't change the data memter
//They are only for accesing
s2 = _T("abc");//works the keyword mutable is given
return s1;
}
//U have to read more on const object too

Glad you mentioned that, because it is important and I have found that aspect very useful. Although that ability needs to be used with great care and forethought, as it can easily be misused.

Hi All.
I have problem, in my program I use 4 thread and thay all use:
<br />
<br />
wchar_t* MyFolder(wchar_t* pSearch)<br />
{<br />
wchar_t Folder[2048]= {L'\0'};<br />
size_t n=0; <br />
<br />
wcscpy(Folder,pSearch);<br />
<br />
for(n=wcslen(Folder); n >= 0; n--)<br />
if(Folder[n] == L'\\')<br />
{<br />
Folder[n+1]=L'\0';<br />
break;<br />
}<br />
<br />
return Folder;<br />
}
this function, and wen I debug it, I olvais have problem to this function.
I think thare is one of two:
1) I have not much experience
2) I do some mistake [in threads or in this function].
can help?

Folder goes out of scope when the function exits so you should not return a pointer to that memory. Allocate the memory using new() or allocate the buffer in the calling function and pass it to this function
System.IO.Path.IsPathRooted() does not behave as I would expect

As indicated by Josh, the problem is because, you are returning address of local object. Create it on heap, and return it.

This is in fact very bad coding practice, It causes unnecessary multiple calls of a functions.
Modify it to,
size_t n =wcslen(Folder);
for(n; n >= 0; n--)

Actually it doesn't. wcslen() is only called once.

Add handler for it.
Are you sure ON_WM_CLOSE() is there in message map ?
|

|
|

Yes ofcourse I have added.

Hello,
I have been searching for this but can't find any answer. I would like my app to be able to handle left-click on popup menu (not menu items). Suppose my menu is:
Item 1
Popup > PopupItem1
PopupItem2
Item2
Everybody known how to handle left-click on Item1, Item2, PopupIem1 and PopupItem2. But how can one detect a left-click on the "Popup" item? Is this feasible with a regular CMenu instance?
Thanks!

Hope I understood you!
This is from the documentation...
TPM_LEFTBUTTON If this flag is set, the user can select menu items with only the left mouse button.
TPM_RIGHTBUTTON If this flag is set, the user can select menu items with both the left and right mouse buttons.

No sorry this is not my point. This will not add a notification if the user clicks on the "Popup" item. This will only change the behavior when clicking on "real" menu items.

Hi.
In my application I have added a listbox on a dialog box. This list contain numbers of elements that user has to scroll so much to see all the contents.
I want to minimize the scrolling efforts of user and I want to provide auto scrolling to the list box. The elements of the list box should get scroll automatically when user movies the mouse pointer over scroll bars of the list.
How I can proceed to achieve this?
Thanks

What would be the difference between an registered dll and a normal dll that doesn't have to be registered, would there be any performance differences?
Many Thanks

Assuming the DLL's are the same as far as their core code is concerned, No.
