When I click a tab page I want to be able to set a flag to indicate to the system that this page has been visited.
Something like OnGetFocus(). Does such a funciton or something similar exist?
Basically when a page gets focus it needs to ensure that any activity on its sister page has been saved before it can proceed, so the sister page will need to have set something

Hi
I have done something like that before... the information on the previous tab needs to be save when another tab is selected.. this is what i have done...
1. Create a variable to store the selected tab...
2. Use OnClickTab to find out which is the newly selected tab...
3. Check if different from last selected tab - if true... prompt save and save previous tab...
4. Refresh the information on the new tab...
5. Save new tab selection to variable
I hope this helps...

OnClickTab - Now that sounds like a very good idea. I'll try it out...
Thanks

A page will have an invalid window handle until it has been visited at least once.

This is what OnKillFocus() is for.

How to know whether the sound card is an 5.1/7.1 channels audio supported card by code?

can someone please explaing what type is UINT_PTR. Is it pointer to unsigned integer or just an alias for unsigned integer? 
after looking in basetsd.h file I found it is defined as :
typedef _W64 int INT_PTR;
so it seems it is unsigned integer, but then why people at microsoft has choosen such an ambiguous name for it or is it just PTR doesnt mean pointer and I am misinterpreting it. 
thanks

Like Johann said, it's used to treat a pointer as an UINT. There's INT_PTR, which treats the pointer as an INT and so on.
Pretty useful for writing platform independent code. Simply casting a pointer to unsigned int won't work on a 64 bit platform, for example.

There is 2 definitions for UINT_PTR:
if _WIN64 is defined it is a unsigned __int64 (a integer on 64 bit)
if not it is defined as an unsigned int (a integer on 32 bit)

Hi,
i hold a pointer to an instance of an unmanaged c++ class in my managed c++ class. just like in the example i found on msdn.
msdn example
This example don't works. I get an unresolved extern symbol error, caused by calling m_pC = new CppClass();
Is there anybody who can tell me how i can create an instance of this CppClass?
Thanks
|
|
|
|
|
the only reason an "unresolved symbol" could occur on such a line is when you declared your CppClass class in its own .h header file, and forgot to #include"" this header in the .cpp file that uses it...

no... everthing is declared in the same header file. I really have no idea what i do wrong.
I just take the given example into one header file.
|
|
|
|

so, what it the exact denomination of the error please ?
