In a simplicistic approach you may just try to open ports iteratively. The call will fail on not available ports (i.e not existing or busy ones).

How to programmatically extract or get the signer name and counter-signer name from an exectuable file if it is digitally signed.
Is there any API or any raw method.

You cannot, as there is no such thing. If you wish to use .NET features from C++ then you must write your program using Managed C++.

Question regarding updates

Hi,

I'm running Visual C++ .Net 2003 with Service Pack 1, and .Net Framework 1.1, and I'm having issues with using GetComboBoxInfo and GetScrollBarInfo, even though they are available as functions when using the intellisense.

Although I've seen, tried and used a workaround to use the GetComboBoxInfo function, I was wondering if there is an update I need to install to avoid having to use the workarounds.

TIA

Tony

OOps, I should have elaboarated on that.

Even though I have the option to use the functions, when trying to declare a COMBOBOXINFO or SCROLLBARINFO they come up as undeclared identifier, and GetScrollBarInfo is identifier not found.

As I said, I have used a workaround involving specifically declaring the struct and declaring links to USER32.dll etc.

What I really want to know is if there is an update that takes away the requirement to put so many workarounds in place to use this functionality?

TIA

Tony

Look at the function prototype in winuser.h. Do you have WINVER defined to be 0x0500 or greater?

Hi Guys,

Thanks for your help.
Looking in the project settings I see the WINVER was initially configured for 0x410.

Identifying real MAC address

Hi,

How can we identify the valid hardware MAC address from the list obtained by GetAdaptersInfo API?

For example, in my machine there is a real Network Adapter and a Microsoft Loopback Adapter. I need to get the MAC address of the real Network Adapter.

Thanks in advance!
