Everyone was a noob at one point.

You might want to start with a book like this one:

I wish you lots of luck with your project, and welcome to the world of Windows programming!

Have a look at Codeproject Articles[^] regarding Serial port communication. You can find a lot of samples which handles serial port communication. Now the rest is to interpret the read data accordingly and do the intended operations. If you have more doubts about "how to do x", then please be specific.

Regards,
Jijo.

In your serial communication class you must have an eventhandler which is called by interrupt service and sending custom messages to your mainfrm application class. Handle this custom messages to convert them to windows messages.

Popup Menu

I'd like to make a popup menu with the following code. However my assertion (ASSERT(m_Popup)) always fails. I've no idea what the problem could be. Thanks.

void CChildView::OnContextMenu(CWnd* pWnd, CPoint point)
{
	CMenu PopupMenu;
	PopupMenu.LoadMenu(IDR_P);	

	CMenu *m_Popup = PopupMenu.GetSubMenu(0);

	ASSERT(m_Popup);

	m_Popup->TrackPopupMenu(TPM_LEFTALIGN |TPM_RIGHTBUTTON, point.x, point.y, this);
	// TODO: Add your message handler code here
}

GetSubMenu() only returns a sub menu that already exists.

If you want to create a new one, you must call CreateSubMenu(), and then attach menu items to it with AppendMenu or InsertMenu.

Thaks for the answer. I created a menu (IDR_P), and I thought that loading it would do all the aforementioned, or what is the point in using creating Menu resources?
Of course if I can't get around it, i will use the method you suggested I just thought that using a resource would be simpler. Thanks again.

Does PopupMenu.LoadMenu(...) succeed? If so, is there a popup menu at index 0 in the IDR_P menu?

As a side note, m_Popup is not a good name for a local variable. The m_ prefix is normally used to indicate that a variable is a member variable (member of a class or struct).

Bit manipulation useing "Bit Field" in C++

Joseph Marzbani3-Jan-09 5:43

I have an array of BYTEs named aBytes. As you know, It looks some thing like this in the memory:

1000100110001010100011011011010110110101 ...
memory increase ---->

Now I want to separate 6-Bit chunks from the begin, as follow:

100010011000101010001101101101011011 ...
memory increase ---->

I used this code:

typedef unsigned __int32 BASE64
struct CHUNKS
{
        BASE64    First:6;
        BASE64    Second:6;
        BASE64    Third:6;
        BASE64    Fourth:6;
}*pChunk = NULL;

for (int iCountor = 0; iCountor < Size_Of_aBytes; iCountor++)
{
        pChunk = (CHUNKS*) (aBytes + iCountor);
        //From now on I expected to access my favorite values using <pChunk -> First>, ...
}

But each time, I get wrong values. Where is the problem? Confused | :confused:

Thank you masters!

Hi Jusef,

iCountor is counting 4-byte integers and you want the pChunk pointer to advance by 4 bytes, however aBytes is a char pointer, so adding iCountor to it is not correct. You should use one of these:
pChunk = (CHUNKS*) (aBytes + 4*iCountor);
pChunk = ((CHUNKS*)aBytes) + iCountor;

Smile | :)

What type is aBytes?

I'll presume it's a char or BYTE pointer. You want to increment it by sizeof (struct CHUNKS), as you want to manipulate items of that type. One wrinkle - making sure you don't increment off the end of the byte array and making sure that all of a CHUNK is in the array.

Anyway - try this:

for (int chunkCountor = 0; chunkCountor < Size_Of_aBytes/sizeof (struct CHUNKS); chunkCountor++)
{
        pChunk = ((CHUNKS*) (aBytes)) + chunkCountor;
        //From now on I expected to access my favorite values using <pchunk -=""> First>, ...
}</pchunk>
