What's wrong in having a copy c'tor in base class, too. That would take care of this.

Check if you are duplicating button ids in any way. or using wrong message mappings.

CWnd::PostMessage internally calls win32 ::PostMessage. I'll use CWnd::PostMessage, if I've CWnd object(no need to wrap window handle, specially to use this version), and ::PostMessage, if I've window handle.

You already got answer in earlier post. If you want to pass pointer to handle, use address of m_hHandle member variable, which is handle of CMainFrame. No need to call GetSafeHwnd.

Use second parameter of CreateDispatch to check what's causing it to fail. See COleDispatchDriver::CreateDispatch [^] for it's usage.

difference is,later function takes one extra parameter. Actually, CreateWindow is a macro, expanding to CreateWindowEx with NULL(no extended style) as first parameter. In effect you are using only one function.

Check your build configuration. If it's been set to any non debug mode. It happens sometime.

Something like this is much faster,

std::ifstream stream("c:\\test.txt");
if (stream.good())
{
std::stringbuf buf;
stream>>&buf;
std::string str(buf.str());
stream.close();
}

But, why one would like to do that ? Heard of need for copy c'tor and assingment operators ? Or dangling pointers ?

Effectively, here you are trying to create CMyView again, where it already exists. You may want to do something like this

CRect rect1( 100, 200, 300, 400 );
m_wndYouwantotCreate.CreateEx( 0, NULL, TEXT("Graph"), WS_OVERLAPPEDWINDOW|WS_CHILD,
rect1, this, 0 );

I'm note sure, but in such cases, deleting .ncb file and other temp files from project folder does the trick.

is this compiler only for C++.Net

It can be used for unmanaged(only) code as well.

I just have the global function body in the .cpp file and including this file in places where I am calling it.

You should not include cpp file in other files. Do , what I said in my first post.

I have an .cpp file which contains a set of utility functions like TrimMyString() etc which could be called a lot of times.

I assume you have declared its prototypes in a header file, and are using it wherever that function in needed , isn't it ?

SizeThreadProc()

Looks like callback function. Must be adding up size of individual file in folder structure.

Not in my information. There needs to be a class(article) for this requirement. So you should understand there is no such API.

As windows calculates size very fast

Have you tried class in given link ? Isn't that fast ?

Check XFolderSize[^] from Hans Dietrich.

_bstr_t s1(v1);

In addition to checks suggested by CPallini, I suggest to you to read VARIANT's doucmentation. If it really contains strings, it can be used as v1.bstr.

// will this array get released after the function over

Yes, You don't need to worry about memory, as its been allocated on stack.
