Where is the counterpart to this allocation?

I have a problem is that how to return an char array from C++ DLL (This array has big data) to VB 6.0 DLL.

Take a look at this article ^.

It sounds like you need to use a SAFEARRAY.

I know SAFEARRAY , BSTR, LPSTR all are good option to return character array (Large data) which is recognized by VB 6.0 as a string. But please give me an example that how to implement them.

how to send command to the server after being connecting by telnet
|
|
|
|
|
Same way that you would send anything via a socket connection. Using the send function. Pass the command you want to the server thru the Send function.
There are alot of Telent articles here so, do a search and take a look see.

Hi,
my list isn't behaving the way I want it to. I have the following code which I step through in the debugger.
<br />
std::list<int *> testList;<br />
int * one = (int *) 0x01;<br />
int * two = (int *) 0x02;<br />
int * three = (int *) 0x03;<br />
testList.push_back(one);<br />
testList.push_back(two);<br />
testList.push_back(three);<br />
one = two = three = NULL;<br />
three = testList.back();<br />
testList.pop_front();<br />
two = testList.back();<br />
testList.pop_front();<br />
one = testList.back();<br />
testList.pop_front();<br />
In the end I get all three int * variables to be 0x03 which is not what I intended with this code. And yes, I am trying to create a list of pointers because eventually it will be a list of pointers to a class representing an image which I don't want copied on each enqueue and dequeue operation.

I didn't notice when I pasted but the <int *> template didn't paste with my code. I do have it there:
std::list<int *> testList;
|
|
|
|
|
I see why the variables are all equal to three. Sorry, stupid question.
|
|
|
|
|
Replace all the pop_front() by pop_back().
What you are doing here is reading the last element of the list then removing the first one. Then reading again the last (which is of course the same because you removed the first and not the last one).
Hope this helps...

Go to the following site:
MSDN downloads[^]
download the emBedded Visual C++ 4.0 and also the Service pack 4.
Also you best get Active Sync, which eVC uses to initiate a connection with mobile devices.

Hello!
How can I determine the height in pixels of status bars? The GetSystemMetrics function seems to give many such values, but doesn't support status bars??
Best regards

Perhaps you could try getting the dimensions of the CStatusBarCtrl that is contained within a CStatusBar?

The size of a status bar is application-dependent. You'll need to take the height of the main window and then subtract other heights from it like caption, menu, non-client area, and border. There may be other values, too.

Get the window handle to the status bar's window.
Then can call GetWindowRect.
Take the height of the rectangle as the height of the status bar.
|
|
|
|
|
How can I get the handle?
I tried the following from my View-class:
<br />
CMyView::OnInitialUpdate()<br />
{<br />
...<br />
<br />
CRect rcStatusBar;<br />
<br />
CFrameWnd* pFrame = (CFrameWnd*) GetParent();<br />
CStatusBar* pStatusBar =<br />
(CStatusBar*) pFrame->GetControlBar(AFX_IDW_STATUS_BAR);<br />
CStatusBarCtrl& statusBarCtrl = pStatusBar->GetStatusBarCtrl();<br />
<br />
statusBarCtrl.GetWindowRect(rcStatusBar);<br />
<br />
...<br />
}<br />
But this leaves me with a CRect with the size of 0 height and 0 width...

These are all MFC Window objects. It is possible that during the OnInitialUpdate that the true 'window' have not yet been created?
You can check with:
::IsWindow(pFrame->m_hWnd)
and if that is not true, your windows don't exist yet, so all widnow rectangles will return empty rectangles.
You might have to investigate something like RecalcLayout and call it from some other location once the windows exist.

Hi
I have a client server application.
Server is an mfc dialog based application.
Client is an mfc sdi application.
Winsock2 is used for communication.
Both client & server are asynchronous in nature credits to WSAAsyncSelect().
The client & the server are connected to each other:
Now whenever i close the client socket, FD_CLOSE notification is send to the server but the vice versa is not happening.
The client donot gets the FD_CLOSE notification when the server socket is closed.
What cud be the possible problem?
waiting for suggestions
Regards
