That might be correct, but not very accurate (IMO).

It's free as long as you use, as suggested, a free webservice.

Other than accuracy, you've to read carefully the terms of use for the webservice, I suppose.

... and you'll probably never get it, because IP addresses are not allocated that way.
Associating an address with a place is something that can be done only at a very high level. As you go down towards the single addresses the number of exception to the general rules are much and much more.
Every multinational company that own hos own autonomous system can get addresses on one regional registry, and displace them around his world. And there is no "central authority" collection all this informations.
What commercial software do is typically recourse into the provider's whois databases until they can. The answer this way can be 90% accurate.
But the problem is that the reamin 10% is not "almost accurate" is simply completely false.
If you wan more infos try google some of the buzzwords of this post.

Download - C Library Module and link it to your app.
IP2Location C Library
http://www.ip2location.com/c.aspx
Developers can use the API to query all IP2Location™ binary databases for applications written in C
to find the country, region, city, coordinates, zip code, time zone, ISP, domain name, connection type,
area code and weather that any IP address or hostname originates from.
Sample Source Codes
#include <IP2Location.h>
int main()
{
IP2Location *IP2LocationObj = IP2Location_open("../data/IP-COUNTRY-SAMPLE.BIN");
IP2LocationRecord *record = IP2Location_get_all(IP2LocationObj, "161.11.12.13");
printf("%s %s %s %s %s %f %f %s %s %s %s\n,
record->country_short,
record->country_long,
record->region,
record->city,
record->isp,
record->latitude,
record->longitude,
record->domain,
record->zipcode,
record->timezone,
record->netspeed,
record->iddcode,
record->areacode,
record->weatherstationcode,
record->weatherstationname);
IP2Location_free_record(record);
IP2Location_close(IP2LocationObj);
return 0;

Case 1
I have created a sample MFC Static library which has the required function definitions in mfcextent.cpp and declarations in mfcextent.h. I have added a MFC test dialog based application for the MFC static library in the same workspace. I included the header file mfcextent.h in the test application project and made call to the 2 functions in the library StringToFloat() and IsNumeric(). When I build the MFC Static library, its build without any errors whereas when I build the test application its giving me link errors as defined below.
Linking...
ExMFCStaticLibTestDlg.obj : error LNK2001: unresolved external symbol "double __cdecl MFCExtensions::StringToFloat(class CString)" (?StringToFloat@MFCExtensions@@YANVCString@@@Z)
ExMFCStaticLibTestDlg.obj : error LNK2001: unresolved external symbol "int __cdecl MFCExtensions::IsNumeric(class CString)" (?IsNumeric@MFCExtensions@@YAHVCString@@@Z)
Debug/ExMFCStaticLibTest.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.
Case 2
When I created the same test application separately and added the static lib output file to the test application and included the header file mfcextent.h, its building without any errors and working fine.
Can anyone explain why case 1 is giving link errors. Am I missing out anything..?
Thanks

So you have the answer. You must include the lib file in your project's linker options - Properties -> Linker -> Input.

Appreciate your help. Can you please explain it step by step how can i Link the lib file.
|
|
|
|

I thought just did. Select your project's properties and go to the Input item under Linker. Add the name of your lib file, and its location, then build your project and the link process should work.
This is assuming you are using one of the Visual Studio IDEs to build your project. If you need to do it manually then check the LINK options in MSDN.

I got it. Its working well. Thank you very much Richard.

I created a function that receives several arguments.
The function processes text and stores it in a variable.
char* Value = NULL;
function (arg, arg, arg, Value);
function declaration
function (arg, arg, arg, char *Value)
I did a read out from within the function, and the result is successfully stored in my desired Value.
However when the function returns to continue.
A CRT_DEBUGGER_HOOK exception is thrown!

|
|
|
|
It would help if you posted the code within the function.
|
|
|
|
|
If my mind serves me right, then this should go smoothly!
functionA(const char* Text, char *Value);
char *Value;
functionA (Paragraph, Value)
If functionA creates a char array and adds it to Value argument, when the procedure finishes whatever condition Value was will remain the same. Or is that incorrect?!

Correct. However whatever Value points to may have been changed by functionA().
It's time for a new signature.
|

You're correct.
This is because the pointer variable is passed by value.
If you want it to change you must either do this -
functionA(const char* Text, char** Value)
char* Value;
functionA(Paragraph, &Value); Or do this -
functionA(const char* Text, char*& Value)
char* Value;
functionA(Paragraph, Value);
|

|
|

Add & and it fixed it!
I tried adding & to the value being passed in the function, but the IDE started underlining red for errors.

Please post the code that is showing errors.

How can I get the standard behavior of hiding menu bar when pushing Alt key and showing the menu bar when I click on the App. e.g Internet explorer. I know how to capture the Alt key and doing manually, I just think this might be part of windows behavior though?
Any ideas?

if you open internet explorer, you push the Alt key, it toggles the menu on and off. To get that behavior in my MFC application, I can do just that by capturing the Alt key and showing/hiding the menu. I was wondering if this comes built in though with some kind of toggle?

For me, the Alt key sets and removes focus on the File menu. I've never seen a menu disappear as the result of pressing the Alt key.

On my IE (ie8 64bits) menu-bar is not visible, and when pressing alt, it is displayed.
In my experience, pressing alt will display the "_" under the mnemonic.
Watched code never compiles.
