Watch-out for typos in your program in the operator =, you've used CounterPointer instead of CountedPointer

Hi All,
I am trying to get a splitter window for MDI when a Menu Item in Menu is clicked. The splitter window is been created but when i am trying to drag that Splitter it is not able to split also it is not performing the events of the pane. (i.e) if in Pane2 of the splitter i am having a Button Control it is not been handled.
Help me out!
Thanks,
Uday.
Here is the Code.
-----------------
void CMainFrame::OnMytreeTree()
{
CCreateContext ctx;
ctx.m_pNewViewClass = RUNTIME_CLASS(CudayView);
// GetActiveDocument() call before you destroy m_splitter.
ctx.m_pCurrentDoc = GetActiveDocument();
//ASSERT(ctx.m_pCurrentDoc!=NULL);
// m_pSplitter !=NULL when there is a visible splitter.
if (m_pSplitter)
{
// Destroy splitter window.
delete m_pSplitter;
m_pSplitter = NULL;
// Create and initialize CMyView.
SetActiveView((CView*)CreateView(&ctx));
GetActiveView()->OnInitialUpdate();
}
else
{
if(m_pSplitter == NULL)
{
//MDIGetActive()->DestroyWindow();
// Create new splitter window.
m_pSplitter = new CSplitterWnd;
if (!m_pSplitter->CreateStatic(this, 1, 2))
{
TRACE0("Can't create splitter window.\n");
return;
}
else
{
if ((!m_pSplitter->CreateView(0, 0,
RUNTIME_CLASS(CMyTreeView),
CSize(200, 0), &ctx))
||(!m_pSplitter->CreateView(0, 1,
RUNTIME_CLASS(CFirstView),
CSize(500, 0), &ctx)))
{
TRACE0("Can't create one of the splitter panes.\n");
return;
}
// Initialize the two panes (each containing a view
// associated with the current document).
((CView*)m_pSplitter->GetPane(0, 0))->OnInitialUpdate();
((CView*)m_pSplitter->GetPane(0, 1))->OnInitialUpdate();
SetActiveView((CView*)m_pSplitter->GetPane(0, 0));
}
}
}
// Redisplay frame.
RecalcLayout();
}

Hello,
Can anyone tell me why the "index" variable isn't changing in my while loop, despite the fact that the vector "vec" has several "0." values stored in it? My goal is to find the index of each zero value in the vector "vec". The very first value calculated for the "index" variable is correct, but for the following loops in the while statement, it never updates from this value.
Thanks!
vector <long double>::iterator varying_start;
varying_start=vec.begin();
vector <long double>::iterator start;
start=vec.begin();
while(true)
{
varying_start= find(varying_start,vec.end() , 0.);
int index=varying_start-start;
}

Don't you want to use varying_start= vec.find(varying_start,vec.end() , 0.); instead of varying_start= find(varying_start,vec.end() , 0.);? I'm not saying this is the answer, but it could be.

Hello,
If I do that then I get the following error:
eror C2039: 'find' : is not a member of 'std::vector<_Ty>'

What are the elements of your vector?

Because varying_start always "points" to the same starting location. Increment it after the index assignment. You'll also want to provide a way out of the while() loop.

You need to increment varying_start after the assignment. You also need to check the return from find() to see whether you have hit the end of the vector.
[edit]I see David posted the answer while I was running my tests[/edit]
It's time for a new signature.

The problem is that when std::find succeeds it's referring to an element holding a zero. At the moment when you call std::find again the first element in the range with a zero in it is the one it's just found.
for( std::vector<long double>::iterator start = v.begin(); start != v.end(); )
{
start = std::find( start, v.end(), 0 );
if( start != v.end() )
{
indices.push_back( start - v.begin() );
++start;
}
}
You can probably collapse a few of the lines down a bit but it's probably not worth it unless you like code to tease the reader.
The important differences between this and your original version is the ++start line. If you find a zero it bumps the iterator past it so the next call to find doesn't return hit the same thing again.
Cheers,
Ash

Thanks Ash.

Hi,
Does anyone know if have to create a copy of IRichEditole
before SendMessage EM_GETOLEINTERFACE
Thankx
|
|
|
|

Please provide some more info what you mean. If i go by my guess about what you mean, then no, you just need an IRichEdit pointer which will be set to the instance of the interface when EM_GETOLEINTERFACE returns, as the documentation[^] says.

Hi,
I do the SendMessage EM_GETOLEINTERFACE
in my ::OnInitDialog right after I instantiate
my CRichEditctrl via new
I saw an example on the Codeproject by
Mike O'Niell
for IRichEditOleCallback he instantiates a copy
e.g.
Interface IExRichEditOleCallBack : public IRichEditOleCallback
{
}
on the heap before setting the address inthe SetOLECallBack
was wondering if the same was true for IRichEditOle
Thankx
|

|

I see. Well, in case of the IRichEditOleCallback, as the documentation[^] states, you are responsible to provide an implementation of the interface methods, this is probably why the exsample creates IExRichEditOleCallBack (from IRichEditOleCallback) and feeds that to the rich edit control. He provides implementations of methods that will be called "by the rich edit" (or somesuch) allowing him to execute his specialized code when something needs to be done.
When you query for the IRichEditOle interface, its methods are already implemented, you don't need to make your own instance of it since what you want to do is to use the already impelemented functionality.
I hope this is understandable rather than making things seem to be even more complicated than before.

This thread on nehe[^] is a good start.
It's not a very easy things to do, especially if you want to make it realistic, but the basics should manageable.
Watched code never compiles.
