That is the transmission protocol. I am referring to the application protocol.

"may have no relationship" How do you know? There must be a protocol that indicates this correct?Last modified: Thursday, June 29, 2006 10:36:53 AM -- sorry hit the post button before I finished (ooops)

As long as the data isn't interdependent on one another there is no technical issue I'm aware of that says this isn't a problem. If it is, then you should avoid this and/or use semaphores, etc. and marshalling to help keep the data in check.
To use an analogy, you don't want to receive a answer before you send off a question for the answer first.
So, if the data isn't dependent you should be ok, all normal issues like bandwidth, remote connections capped, etc. notwithstanding.

Your analogy is correct for a transfer model of question/answer, but in this case, the data coming from one direction may have no relationship to the data going in the opposite direction.
Take for example an implementation of a TCP/IP terminal program where the user types on the screen some information that gets sent over the socket, but the other side at any time, could be sending information to be displayed on the screen unrelated to the information being typed by the user.
I assume your use of the word "dependent" means the answer to the question previously sent. Again, that is not the model used.
Thanks for your feedback. It is appreciated!

Yup. Then you should be ok if that's the case.

Yes, it's legitimate. Send and receive buffers are separated, so threading isn't an issue for the IP-stack.

Hi All,
I have a list control in report view with slider controls as items.
When I scroll through the list using the mouse wheel or page up and page down, some of the track bars in the slider controls get changed.
Can anyone help me with this problem? I tried using a progress bar but I get the same problem.

Hi all,
After creating two radio buttons how can

If you are using MFC, you group them (setting the group property on them -- read the MSDN documentation for more details), and then assign a variable to the first one in the group. If you assigned an integer value to it, you would set the integer value to the value of the index in the group. For example, if you have:
IDC_MYRADIO_0
IDC_MYRADIO_1
as the resource names for your radio buttons (make sure they are in sequential order in your resource.h file), and you assing m_iMyRadioValue to represent the data for the radio buttons, you would set m_iMyRadioValue to the corresponding button you want selected:
m_iMyRadioValue = 0;<br />
UpdateData(FALSE);<br />
<br />
m_iMyRadioValue = 1;<br />
UpdateData(FALSE);

If you are using MFC, use CButton::SetCheck(BST_CHECKED). Otherwise, send the control a BM_SETCHECK message. UpdateData() is the wrong choice here.

The control variable should be set in the constructor, or else before claling DoModal for the dialog, and the DDXExchange call made during the call from OnInitDialog would handle it fine.
I agree with David - end user should not be willy-nilly calling UpdateData.

can someone help me??!! can someone teach me how to encrypt a *bmp imgage and then save it using Microsft Visual C++ 6.0??? Thanks loads PLEASE!!!
thanks in advance
|

A Simple one.
Encrypt
1. Read the data of bmp to a file.
2. read it for a buffer.
3. while iterating through from the starting to begining, shift its bits (e.g left shift 4 bits
4. On completing it, save to a file.
decrypt
1. Read the data of bmp to a file.
2. read it for a buffer.
3. while iterating through from the starting to begining, shift its bits (e.g right shift 4 bits
4. On completing it, save to a file.
simple no?

Don't take this the wrong way, but you might want to start with something a bit simpler than reading in a bitmap file and encrypting it when you are new to programming (especially new to C/C++ programming).

do you mean rotate each byte 4 bits? or do you mean shift the entire buffer four bits (push bits onto adjacent bytes) ?
either way, it's much simpler to just XOR the bytes with a mask of some kind.

Hi all,
I previously used Windows Forms so i'm experiencing some
difficulties with MFC.
I created a combo box, i wrote
a;b;c;d; in the Data field
but when i launch the application and

nothing happens ? Why ?
Thanx in advance,
Desmo16.

it will able to do it, when click on the drop-down button of the combox box when at resource editor.

sorry but i didn't understand what you said.
I simply put a combobox from the toolbar onto the form
and wrote a;b;c;d; on the data property of the combo box ?
Is there any code to write or other actions to do ?

Your question is somewhat ambiguous. Is the combobox not dropping down? Is it disabled? 
When creating a CComboBox control you should set the style to:
WS_CHILD | WS_VISIBLE | WS_TABSTOP
also add to the style:
CBS_DROPDOWN or CBS_DROPDOWNLIST
The MSDN help docs topic on CComboBox::Create() links to a list of all combo box styles.

it's everything ok now, thanx.
i just wasn't able to expand vertically the combo box in design view.

Is there an easy way to send CString data to a RichEditView?
I tried using Visual C++ 6.0 to create an SDI app and then dumped older code where I assigned text to a Arrary of CStrings in the view class using the pDoc pointer and then calling Invalidate() to invoke the OnDraw() function to perform the pDC->TextOut() function. Is there something similar for the RichEditView? In my attempt to copy and paste code I was unable to get into the CRichEditView::OnDraw() function.

First call GetRichEditCtrl() to get a reference (not a pointer) to the view's edit control, then call SetWindowText(), like:
CRichEditCtrl &edit = GetRichEditCtrl();
edit.SetWindowText("Hello");
