But I get data from the database, so the document is not necessary, any better way?

Since you mentioned CFrameWnd and CView, I thought you were using a doc-view style CWinApp. Using the doc-view makes it easy to do the switching since you can use the the internals of the MFC stuff. The CDocument contents are not really needed - I usually have a CMyDocument class with nothing but a constructor, and multiple CFormViews that I switch between.
It doesn't get much simpler than the link I gave.

I need to iterate over a std::string and replace every occurance of '\' with '/'.
There are different ways:
I could use the index operator [],
Or I could use the iterator begin()
What is the accepted way to do this?

Or you could be really brave and use the replace() function.

The replace method requires you to specify the character positions that you want to replace.
This means you must still iterate over the string. No?

That's one option.

Well I've looked at all the overloads and that appears to be the only option.

Direct memory access would always faster. but there you have to check for upperbound of string array

What does this have to do with timers?
Did you mean time? If so, you could use the CTime/CTimeSpan or the
COleDateTime/COleDateTimeSpan classes.

What unit of measurement is "time" in? If it's in seconds, add 7200. If it's in minutes, add 120.

 I have a main C++ Routine with an include file called MyMainFile.h. Have a number of global variables in the include file that I want to be visible to a subroutine that is called from the main C++ program. However, when I call the subroutine, and include the MyMainFile.h in the subroutine, none of the variable that are declared in the include file, MyMainFile.h, are available. The compiler designates them as undeclared variables?? Any ideas? Sid Kraft

In the include file use the extern keyword before usual variable declaration, for instance.
extern int myGlobalInteger;
BTW: use sparingly global variables.

guys just a quick one,how can i access or export the data stored in a varible within my dll, i want to access the data from my msvc++ aplication.
cheers Chris

In the DLL declare the variable something like
<a name="more">__declspec</a><a name="more">(dllexport) int DLLInt;</a>
In the EXE, something like
<a name="more">__declspec</a><a name="more">(dllimport) int DLLInt;</a>
Since it's easier to declare things in just ONE place, like
a common header file, you can use a macro that imports or exports
the variable depending on what's getting built, the DLL or an EXE...
<a name="more"><font color="Green">
#if defined(BUILDING_DLL)
#define MY_IMP_EXP dllexport
#else
#define MY_IMP_EXP dllimport
#endif
__declspec</a><a name="more">(MY_IMP_EXP) int DLLInt;</a>

Your solution is probably much more to the point of what he was interested in than mine  .

Hi there
i'm using GetCursorInfo in order to have the handle to the cursor. How can I know what type of cursor do I have ( ex arrow, hand, wait)???

If it's a custom cursor, then you won't know what it is.
For system predefined cursors, you MAY be able to compare the handle to
the handle returned by LoadCursor() for predefined cursors.
I'm not sure if those handles are always the same but it's easy enough to test
