Thanks, but according to MSDN RegQueryValueEx: Retrieves the type and data for the specified value name associated with an open registry key.
and I need to retrieve the path of the key handle.

I think he has a handle and is going to find out which key, the handle, refers to, i.e. He wants to find the key that he opened already and has a handle to it.
//This is not a signature
while (I'm_alive) {
cout<<"I Love Programming";
}

Hai,
This is a program for serial data reception. Can anybody tell me how this code is working. It is programmed to receive 18 bytes (a configured data packet of 18 bytes) of data.......
Code is:
CTimerDlg::OnOnComm()
{
if(m_comm.GetCommevent() == 2) // m_comm is serial member variable
{
UCHAR *parray; // local array
COleVariant var;
var = m_comm.GetInput();
long comL;
HRESULT hr = SafeAraayGetUBound(var.parray , 1 , &comL);
if(hr == S_OK)
{
hr = SafeArrayAccessData(var.parray , (void**)&parray);
if(hr == S_OK)
{
Rxdata[RxBuffcount++]=parray[0]; //local array
}
SafeArrayUnaccessData(var.parray);
if(RxBuffcount == 18) // if 18 bytes received proceed
{
Processdata(); // data processing
RxBuffcount = 0;
}
}
}
}
My questions are:
1. How is this code working.
2. Is this code receiving data bytewise or not .
3. If so how and where to check for the first (header) byte (say 0xaa).
Plz help me.

By default you can create one sample application by clicking few clicks. I think it is easy and you already know about this. why you are still searching againg again? what exactly you need.
To develop explorer style app just do these steps.
-------------------------------------------------
Open Visual Studio . VC++ environment(It can be 6.0/7.x, I am telling steps in 7.x)
1) create new project.
2) Select project type is MFC application
3) Select over view -> nothing to select.
Application type -> Single Document.
Project Style -> Windows Explorer.
4) Click Finish button.
Here you will get One Tree View control. and One list view control in your project.
You can get what exactly you need. It is easy to use for you. Check MSDN for that. MSDN can be used by any one in online. ;P enjoy.

Which part is giving you trouble? Creating windows? Sending messages to a control to get it to
do what you want?

The FindFirstFile, FindNextFile. FindClose APIs can help you get the file names (if you don't
have them already).
Then you need to create a node/item for each file in the tree control (or listview control like
the right-hand window in Windows Explorer.

For free? Maybe for a tab control, but a DYNAMIC tab control...that will cost you.
Umm, what's a dynamic tab control?

that means,tab and dialog or propertysheet will increase at run time based on input.

will increase or created at runtime!

if you want to increase then you have to look at api like SetWindowPos and MoveWindow and if you want to create same at runtime look at CTabCtrl::Create!
