Thnx for the reply,
But what has this to do with sending test on the right way?
I just want to know how I can send or receive text (in string-format) in its simplest form using CArchive and WriteString() and ReadString().
If my application works, I forget all my problems.

what I think he is trying to say is check for error return values at every point, initialization to send/receive. Also since you did not include the initialize routine he showed, it may be as simple as initializing properly. The greater part of programming is learning how to find your own answers. Know what is wrong, and you can fix it. Run in debug mode, step through the operation, check error return values. Most of us do not have time to take your code, compile it into a full executable, discover the answers and give it back.
I highly recommend running in debug mode. at least then you can say all the return values operate as if they are actually sending the information, but I am not receiving it.

Does anyone know where to find information on implimenting key binding/mapping?
Any information: articles, books, BBS, key words that will narrow the search, ect...
I wrote a text/code editor program sometime ago, that works much like the editor in VC++. One of the problems I need to solve is custimization of key bindings. At the moment, the key comands are built in (hard coded) and I to eleminate that aspect of code.
Thanks!

Hi
I need to popup a menu after I click a button on a toolbar. How can I find the position of the button?
Thanks

CToolBar::GetItemRect(). Use CToolBar::CommandToIndex to get the index if you have just the command ID.

Hi I'm getting an unhandled exception in MSVCRTD.DLL Stack Overflow.
Basically I can't see where it's coming from. The below try block call's itself recursively and doing some other stuff along the way until a global count has been reached.
The only exception i can trap is the catch all. Is there anyway of determining the type of exception? I can't work out where it is being thrown from? 
code:
try
{
AddNextCallToPlayList();
}
catch( CMemoryException* e )
{
LOG_ERROR(_T("CMem\n"));
// Handle the out-of-memory exception here.
}
catch( CFileException* e )
{
// Handle the file exceptions here.
LOG_ERROR(_T("CFile\n"));
}
catch( CException* e )
{
// Handle all other types of exceptions here.
LOG_ERROR(_T("CException \n"));
}
catch(_com_error e)
{
LOG_ERROR(_T("catch com\n"));
}
catch(...) //__except(EXCEPTION_EXECUTE_HANDLER)
{
LOG_ERROR(_T("catch all\n"));
}

Either remove the catchall or set stack overflow exceptions to break into the debugger. Then you can look at the call stack.

I'm going to patent thought. I have yet to see any prior art.

The problem is that it runs through this code at least 137 times without causing a problem. If i remove the catch all the stack is showing the current function but no where near anything that could cause a problem.
How do i set set stack overflow exceptions?
Your comments are appreciated

It sounds like the stack overflow is being caused by unbounded recursion. Check to see if this function can be called recursively somehow, and if it is, make sure it doesn't get called too many times.

It is being called recursively. How can i achieve this successfully?

You need to include some code to prevent the recursion from going too deep; you need to reduce the number of times the function is called recursively. How you do this is up to you, but you may need to convert the algorithm to an iterative one. If you can limit the depth of the recursion without ruining the algorithm then that would be the best option.

Hi...
How can I simulate pressing the tab key with enter key. I have 5 edit controls in my view and I want to jump to the next edit control not by pressing the tab key but by pressing the enter key. I tried like this
BOOL CMyView::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->wParam == VK_RETURN)
{
PostMessage(WM_KEYDOWN, VK_TAB, NULL); UpdateCalc();
return 0;
}//if
return CFormView::PreTranslateMessage(pMsg);
}
this works exept, that this code simulate's a double key press of the tab key.
Please Help!
Thanks
My question is:
|

|

|

this works but still the code executes 2 times. Let's say that my position is on the first edit ctrl. When I press the enter key for the first time this segment of code is executed:
if(pMsg->wParam == VK_RETURN)
{
PostMessage(WM_NEXTDLGCTL); //the first time
UpdateCalc();
return false;
}//if
But after that the focus goes to the next edit ctrl?????

i think this could be done without simulating any keystrokes using SetFocus(...) and GetNextWindow(...) functions
|
|

|

Try to use the following code instead:
BOOL CMyView::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->message==WM_KEYDOWN)
{
if(pMsg->wParam==VK_RETURN)
{
pMsg->wParam=VK_TAB;
}
}
return CFormView::PreTranslateMessage(pMsg);
}

Thanks. I'm sure this will help.

If you return TRUE instead of 0 from this method
then the initial return key should not get processed further?

Hi 
I have a dialog which I want to be able to have detect a user clicking on and off the title bar. I can detect the left button down on the title bar by implementing CDialog::OnNcLButtonDown() which corresponds to ON_WM_NCLBUTTONDOWN(). Now what I want is to detect the left button being released. I've tried CDialog::OnLButtonUp() which corresponds to ON_WM_LBUTTONUP() and of course CDialog::OnNcLButtonUp() which corresponds to ON_WM_NCLBUTTONUP() but they do not seem to get called (I make an AfxMessageBox() call in them to check). I can get CDialog::OnNcLButtonUp() to be called by double-clicking the title bar but not when just releasing the mouse button. Can anyone help with this?
Thanks

Aside: You may want to replace the AfxMessageBox() call with TRACE(), since the former causes a change in focus.

This behaviour is caused by the default processing of the WM_NCLBUTTONDOWN message. When it processes this message, it enters a loop whereby it moves the dialog if the mouse moves, and exits the loop when it receives a WM_NCLBUTTONUP message. The fix is to not call the default processing for WM_NCLBUTTONDOWN. The problem then is that the user cannot move the dialog, so you'll have to implement the code for moving the dialog yourself.
Hope this helps,

Your dialog should get a WM_MOVE message after the window has been moved (and WM_MOVING messages while
it's dragged).
Wouldn't that be enough ?

Hello !
I use the function CreateFile to open a COM port. Everything works fine unless the port number is only 1 digit (up to port 9). When I try top open the COM port10, the function returns INVALID_HANDLE_VALUE and a call to getLastError() gives me ERROR_FILE_NOT_FOUND (2).
Here is the code:
hCom = CreateFile(pszPortName,<br />
GENERIC_READ | GENERIC_WRITE,<br />
0, <br />
NULL, <br />
OPEN_EXISTING, <br />
0, <br />
NULL <br />
);<br />
What is the problem ??
