Hi,
While running my application how can I keep track on any key event so that key logger should not get to know about pressed key?

I suppose your application cannot prevent a keyboard hook to do its job, if that was the question.
 If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

It really depends on your application. You may for instance, avoid keystrokes providing a virtual keyboard (graphical representation of keys, mouse activated).

If you want to keep track of the key events, then i suppose, your application wants to know whether any one is hooking the keyboard events.
Then surely it may be using SetWindowHookEx([^]) to achieve the goal of a key logger.
To find the Key logger, you can use the technique of API hooking to monitor any process doing something with a specified API.
Hook that API(API Hooking (LoadLibrary)[^]). I believe if you hook SetWindowHookEx API then you can monitor whether some one there for KeyBoard hooking.
A little bit complex, All the best, have a try Величие не Бога может быть недооценена.

I could user ip helper api (NotifyAddrChange and NotifyRouteChange) to get the notification when the user changes the IP address,subnet mask ,
but when the dns server address( main and the other) is modified , I could not get notification.
Is there any method ?
Thanks!

the three points ( center, start of arc ,end of arc) and the angle are known to me. I need to draw whenever these values are given. I saw CPie but for that you need to know the rect.

|
|
|
| I would imagine that you have enough information to calculate the bounding rectangle. Please do not read this signature.

As mentioned above, you got all the information needed. Now its time for mathematical calculation.
Now i cannot understand, what's the hurdle in front of you to do that calculation  Величие не Бога может быть недооценена.

Please observe this formula
to find the distance between two points[^] 
Now you could find the radius (R = d) of your circle:
P1(x1, y1) - center point,
P2(x2, y2) - start point
Then you could determinate the rectangle (rc) :
rc.left = x1 - R;
rc.top = y1 - R;
rc.right = x1 + R;
rc.bottom = y1 + R;virtual void BeHappy() = 0;

thank you . My idea of bounding rectangle was wrong. Anywayz hankz for the very precise answer.

Arc[^]
AngleArc[^]
ArcTo[^]
Enough for you?
Ellipse and Arcs in GDI+[^]
I'd also look at GraphicsPath in GDI+ before. That way, you can "draw", and then break that into it's points.
I hope that came close to an answer for you.

Hi,
I have an MFC app that is dependant on an external windows service. The need to restart that service occasionally arises.
I do this using some boilerplate code, heavily derivative of that appearing in an article on MSDN. When I run the application on Vista as a non-administrator, a call to OpenSCManager() returns NULL. I must run the application as an administrator for the process to succeed.
Can I make a UAC dialog automatically appear on Vista/7 in the event of needing to access administrative functions like this? I have similar problems in the same application when calling code that uses boost.asio to ping a remote server.
I'm not sure if it's relevant, but here is my application manifest security entry:
<!-- Identify the application security requirements. -->
<ms_asmv2:trustInfo xmlns:ms_asmv2="urn:schemas-microsoft-
com:asm.v2">
<ms_asmv2:security>
<ms_asmv2:requestedPrivileges>
<ms_asmv2:requestedExecutionLevel level="highestAvailable">
</ms_asmv2:requestedExecutionLevel>
</ms_asmv2:requestedPrivileges>
</ms_asmv2:security>
</ms_asmv2:trustInfo>
Thanks a lot,
Sternocera

This one might help

change to

For that, you must set UAC options for your projects.
linker option in the Visual Studio development environment must be changed.
->Open the project's Property Pages dialog box.
->Expand the Configuration Properties node.
->Expand the Linker node.
->Select the Manifest File property page.
Modify the
1.Enable User Account Control (UAC)-Yes
2.UAC Execution Level-highestAvailable
3.UAC Bypass UI Protection properties-Yes

Hi,
Doing so doesn't make any discernible difference,

 Hello everyone,
I'm having problems with large integers that get stored in a stream and then transferred to a string variable showing up in scientific format once the string "string_first_col_intcheck1" is printed out (despite using "unsetf" options). Any ideas?
int int_value=1150000;
ostringstream oss1;
oss1.unsetf(ios::scientific);
oss1.unsetf(ios::showpoint);
oss1.unsetf(ios_base::fixed);
oss1.unsetf(ios::scientific);
oss1<<int_value;
string first_col_intcheck1;
first_col_intcheck1=oss1.str();
Result is that "first_col_intcheck1" is printed out as "1.15e+006"

The number of digits (7) must be exceeding the precision of the stream. Use the precision method to change it.
oss1.precision();
|

Thanks Gwenio!
That did the trick, I was thinking "precision" was for decimal numbers but that is "setprecision".

Hello all, I am getting segmentation faults when I call my deleteTree function I was wondering if someone could explain why and what I am doing wrong.
Here is the snippet I am having trouble with:
qnode *
deleteTree (qnode *root)
{
int i;
if (root == NULL)
return root;
if (root->children[i] != NULL)
{
for (i = 0; i < 4; i++)
{
deleteTree(root->children[i]);
free (root->children[i]);
root->children[i] = NULL;
root->leaf;
}
}
}
Thank you for your time,

Did you read the second post in this forum? Narrow it down to just a small handful of lines or you'll likely receive no help."One man's wage rise is another man's price increase." - Harold Wilson

Could it be because in your code
deleteTree (qnode *root){ int i; if (root == NULL) return root;
if (root->children[i] != NULL)at the time you perform the if statement, i is not initialized?Karl - WK5M

Hallo,
I worked with a Windows XP / Visual Studio 2005 Development environment until a few weeks. Now I upgraded to Windows 7 / VS 2008, and after the conversion of my Project everything works fine in Windows 7.
Then I tried to run my Win7/VS2008 compiled version at Windows XP, and I get an "Unhandled exception 0xC0000005 (ACCESS_VIOLATION)" Error.
Are there some compiler Vars I have to set in my Visual Studio 2008 on Windows 7, that my Program works correctly in Windows XP? Or do I really have to set up Visual Studio 2008 in On a WinXP machine to find the error?
