How to check UAC On/Off

UAC enable information is stored in "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System"
subkey.
In this sub key values, EnableLUA key value present windows enabled UAC or not.
So we can make a simple code that checking a current windows UAC status.

BOOL IsUacOn()
{
DWORD res = ERROR_SUCCESS;
DWORD dwType = REG_DWORD;
DWORD UacOnOff = 0;
DWORD sz = sizeof(DWORD);
res = SHGetValue(HKEY_LOCAL_MACHINE,
_T("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Policies\\System"),
_T("EnableLUA"), &dwType, &UacOnOff, &sz);
if(res == ERROR_SUCCESS)
{
if(UacOnOff == 1)
return TRUE;
else
return FALSE;
}
else
return FALSE;
}

Richedit Control Bug(?)

I've found a quite bothering bug about rich edit control.
1. Create Visual C++ Dialog Based project.
2. Set Character set to "Multi Byte Support" on project property.
3. Open resouce file(.rc) with "view code"
4. We can see following code that rich edit control generated Ansi window class.

CONTROL
"",IDC_RICHEDIT21,"RichEdit20A",ES_AUTOHSCROLL WS_BORDER
WS_TABSTOP,57,60,135,111

5. Then , change "Character set" property to "Unicode character set" on project poperty page.
6. Now, we expected rich edit control's class changed unicode class, "RichEdit20W"...
But It's NOT...
We have to change it RichEdit control's class name to "RichEdit20W" manually on .rc source
code.

CONTROL "",IDC_RICHEDIT21,"RichEdit20W",ES_AUTOHSCROLL WS_BORDER
WS_TABSTOP,57,60,135,111

error C2248

We maybe meet a this error when using class that derived from CWnd or CObject class.
MFC class , CObject prevent using copy constructor and assignment operator.
Because It's can make an abnormal behavior .
To resolve this error we should override copy constructor and assignment operator.

class CTestWindow : public Cwnd
{
public:
CTestWindow();
virtual ~CTestWindow();
CTestWindow( const CTestWindow &s )
{ *this = s; }
CTestWindow& operator=( const CTestWindow &s )
{ return *this; }
};

How to marshal interfaces across apartments in Visual C++

When using a STA COM on multi-threaded environment, we maybe got COM errors.
Because a STA COM Interface could not be shared throuth different threads.
If you want share a COM interface among threads, you shoud marshal a COM interface.
And If Application has a UI, we should message pump, so that It could be blocked while marshalling.
Reference this Microsoft KB article.

Embeded controls on dialog are could receive only defined notify message

Windows System sends WM_PARENTNOTIFY messages to each control windows.
So controls can take a message and behave specify actions.
However, Windows System does not sends message to dialog template control that has
WS_EX_NOPARENTNOTIFY property.
When RC compiles dialog template , each controls create with WS_EX_NOPARENTNOTIFY.
User can not prevent it.
We can only define Visual Studio pre-defined notify messages.
(Mouse left button down/up , etc)

If you want to make controls receive every messages, do not place controls on dialog template.
And create a control via Create(or CreateEx) function.

Parallel Extensions

http://channel9.msdn.com/shows/10-4/10-4-Episode-6-Parallel-Extensions/
In this episode of 10-4, we start taking a look at Parallel Extensions to the .NET Framework. We'll look at some of the surface-area of the Parallel Extensions API and provide you with enough information to start working with it yourself in the Visual Studio 2010 CTP VPC. Remember that we are running these bits within a virtual machine with a single virtual processor, so you won't be able to see the performance improvements from the library. However, you will be able to start get a feel for the API itself. In future episodes, we will dive into deeper details of the various parts of Parallel Extensions. Also, in next week's episode, Jonathan Carter will be back to talk about another new feature in ASP.NET 4.0, so make sure to stay tuned for that!For more 10-4 episodes, be sure to visit:http://channel9.msdn.com/shows/10-4

Using Post Build Step Event.

When developing with many binary objects. like a dll.

After build, we should copy these files to specify folder.

Because it'll work correctly on condition that dll's same designated position.

It's reall tedious and bothering task.

If you know a "Copy" command , you do not need to do this task.

On Visual Studio(since VS6), we can add command that copy some file to specify position,

after build.

On project property page(ALT+F7), Configuration Properties>>Build Events>>Post Build Evnet" add following lines on Command Line.

Copy "[Source]" "[Destination]"

EX>> If you want to copy "D:\test\test.dll" to "D:\BIN\test,dll", add folling lines on Command Line.

Copy "D:\test\test.dll" "D:\BIN\test,dll"

After setting applied and build, You will see a "Copy success" message on a output window.

Virtual PC error loading existing image after re - install a virtual PC

After re-install a Virtual PC, You'll be meet an error message when loading existing image.
Error message is "Your Virtual PC does not compatible with this virtual PC image."

You can solve this problem by deleting a " [VPC_Image_Name].vsv" file located in Virtual PC Image folder.

Use unary_function when delete objet in STL container.

This post copied from Effective STL.
Usually, many developer still delete object in STL container via iterating container and delete.
This method possibility makes exceptions and not effective way for STL.
From now on, use unary_function with for_each.

template <typename T>
class ContainerDeallocator : unary_function<T, void>
{
public:
void operator () (const T* ptr) const
{
delete ptr;
}
};



vector<int*> v1;
v1.resize(10);
v1[0] = new int(10);
v1[1] = new int(18);
v1[2] = new int(67);
v1[3] = new int(5);

for_each(v1.begin(), v1.end(), ContainerDeallocator<int>());

It's more pretty than using iterator.
