Also can i hav pointer to the dialog so that i can access its control??

thx

Yes you can use CRegistry class . This is one of the easiest classes to use
See Here for CRegistry[^]
Regarding using a pointer you can see my previous post to this thread.

this is not a class declaration.

the code is defining the default constructor of the CAboutDlg class (a constructor always has the same name as its class). a constructor can have an initialization list, which is the case here ; you can spot it with the : syntax after he function parameters list.

this initialization list tell the constructor the call the constructor of the CAboutDlg class' base class and passes it the CAboutDlg::IDD parameter.

what is missing in your sample is the brackets. i think the code would be at least :

class CAboutDlg : public CDialog {
    //...
 
  public:
    CAboutDlg CAboutDlg(void);
    //...
};
 
 
CAboutDlg::CAboutDlg()
    : CDialog(CAboutDlg::IDD) {
}

You can use the scroll messages for this.
OnVScroll or OnHScroll.

hello friends,,
I have established serial communication with RABBIT3000 (an 8 bit microcontroller).

The packet from the microcontroller is sent to the PC only on the PC demanding it. The demand is sent through one of the variables in the packet sent from PC.

When the PC receives packet from the microcontroller, it receives the correct packet for the first time. During my second request and further,
the Pc keeps receiving the same packet that it received first.
The packet from the microcontroller is updated on some conditions so that its different values in the packet memebers each time it is sent to teh PC on demand.
but when I try sending a different packet (microcontroller updates the packet structure members) to the PC, it still receives only the same packet that it received first and not the updated one.

I receive the packet using Readfile and store the values in a circular buffer.

On the microcontrollers end, the changed values is what is sent in the packet. I have debugged on the microcontroller end and it is fine.
Why is the PC receiving the same packet ?
What could be the possibility? any suggestions?

Thanks in advance.

hi white sky,

There is no problem in the code but i am able to see the CFormView Embeded inside the Dialog. Because in the Button Event i am creating the CFormView and Showing it.

My intention is to Show as another Window for the CFormView. Presently it is showing inside the Dialog window it self. It is not able to show as a separate Window for CFormView when i click the Button in the CDialog.

please help me out.
