I might be on completely the wrong track here but, it's sounds like you are using select() with a 250ms timeout and are using synchronous style comms (i.e. select() will block). Why not take a look at a non-blocking mode of operation and use WSAAsyncSelect()/WSAEventSelect() or use the callback mechanism offered by WSARecv. This will move your code to an asynchronous style of operation and mean that you should pick up all packets, no matter when they arrive.
Hope this helps,
Phil

I am trying to do what the previous post was, only I am not calling the new class. I am using the following code:
extern CHjipaperlessApp theApp;<br />
<br />
CMultiDocTemplate *pTemplate = (CMultiDocTemplate*)theApp.GetDocTemplate(3);<br />
<br />
ASSERT(pTemplate);<br />
<br />
CDocument *pDocument = pTemplate->OpenDocumentFile(NULL)
This launches a view class, but I want to pass an array to this new class. Any suggestions?
Much Thanks,
Michael Shuster

There are several solutions. One solution is to pass in objects via contructor or call some other function after creation.

After the OpenDocumentFile() call, you have a pointer tot he document, can't you just call a function on it and pass it the array as a parameter?
You may have to cast the pDocument pointer to the correct type to do it.

Hi, I have a problem passing variables between classes (I am new to C++) and I am trying to implement a class for data manipulation in VC++.
I have an array loaded from file in the dialog class of the app that I wish to pass to the other class for various operations before being returned to the dialog class for output to a new file.
This is probably a very straightforward query but I am struggling to get this running and would appreciate any advice or help anyone can give.
Thanks,
Charlie.

Use references. Add a member to "the other class" of type reference (ie., CStringArray& m_array). Pass the real array in your dialog class to the class's constructor:
CMyDlg::OnWhatever()
{
COtherClass oc(arrayFromFile);
...
}
...
COtherClass::COtherClass(CStringArray& array) :
m_array(array)
{
}

Hello again, I was wondering if someone could inform me how to display a bitmap and text on a button, if that is possible?
I would at least need to know how to get a bitmap displayed on the button, and could just add the text to the bitmap, if needed...
Also, because I am using API, I would appreciate a no-mfc version of how to do this. Thanks.

I'm programming in visual c++ (vs6) for a while now, and I always get the same difficulties with transferring projects from one machine to the other.
I have 2 machines, both win98. But the first is win98/osr1 in english, the latter is win98/osr2 in dutch.
Transferring projects will always result in resource exceptions. Probably, opening an english resource (...and the whole project) on a dutch machine is impossible. I have to delete half of my project an rebuild it again, loosing much data.
Is there some sort of way that ignores languages in resources? Or maybe a way to kick out all language related problems all together (even better)?
btw. Next to US-english stands this: [standard]. In my opinion, this US-english is not a standard, far from it...
using: [VISUAL STUDIO 6.0 sp5] [WIN98/2]

Hi all,
I am cooding an application for sending key-strokes to an other application. For example, sending a ctrl+C to to the target application. Because the target application will be non-MFC application(e.g Java applet, OpenOffice...etc), it may not be able to use the WM_XX message.
Do you have any great idea to do so?
Cheers,
Tony
Enjoy Coding.

I want to send the pointer of my myCDialog from its OnClose to the parent View. PostMessage has two UINT args I can use. Can I do:
In OnClose()
p_Parent ->PostMessage(myMSG, UINT(this),0)
and on the receiving side in the parent:
OnMyMsg( UINT n1, UINT n2)
{
myCDialog* dlg = (myCDialog*)n1;
}
Appreciate your help,
ns

Yes you can.
<br />
p_Parent ->PostMessage( myMSG, WPARAM(this),0 );<br />

But don't forget that the data that the pointer points to needs to remain valid while you are processing it! i.e. don't do
void CMyWindow::OnSomeMessage()<br />
{<br />
CString strData = "Hello";<br />
m_pMyOtherWindow->PostMessage(WM_STRING, &strData);<br />
}
As the CString will have been destroyed by the time you come to use your pointer to it. In this instance, use SendMessage() instead.

My pointer is a member so its not local so I'll post and not send, but thanks so much for making me aware of the temporariness of the passed in variable...
Appreciate your help,
ns

Yes. Good Point! I was thinking about that. There will be a problem if the dialog goes out of scope.

I have SP5 installed for VS6.0. Now, when I build a project that I've been working on for 3 months, it blows up when it is launched outside the debugger. It blows up at lauch time - the debug version gives me a crash address of 0x00000009, which isn't even in my code yet!. If I compile it on a machine without SP5, it works fine.
Has anyone else seen this?

Have you tried rebuilding the whole project?

I just installed SP5 for VC++ 6, and everything *seems* to be working fine.
|
|
|
|

Indeed mine seemed fine for a while.
I just had to remove dev studio, and re-install it, and apply service pack 4. Everything is back to normal now.

My program is behaving differently when I link with MFC statically vs. when I link with MFC as a shared DLL. (In both cases I an using a debug build, so this is not a debug/release issue.)
The first issue I noticed is with the CRectTracker. When I use a RectTracker while linking with a shared DLL everythink works correctly. The cursor changes when over the rect to a cross and the user can move the rect around the screen. But, when linking with with static MFC the rect tracker does not behave correctly. After the rect tracket is displayed, moving the cursor over the rect makes the cursor disapear. It does not change to the cross, it just disappears when over the tracking rect.
Any ideas what I am doing wrong? Any ideas why this is and what I can do about it? Thanks!

Try a service pack (or not, see my most recent thread...)
I know there were problems with sockets and statically linked MFC, which was supposedly fixed in SP5.

Sir i am setting the options of the ICMP Packet using the function below. As ttl=0 so packet should not be sent but it is not happening packet has reached its destination.
int ttl=0;
(setsockopt(sock,IPPROTO_IP, IP_TTL, (char *)&ttl, sizeof(ttl))
// Send the echo request
if (sendto(sock, (const char *) &echo_req, sizeof(ECHOREQUEST), 0, (SOCKADDR *) &sin, sizeof(sin)) == SOCKET_ERROR)
//plz help me
Reply me soon
|

|

Have you checked the error code returned by setsockopt? According to the MSDN, the TTL does not have to be supported. Also, if your destination is local then the packet may not have to go through any routing devices, and so the TTL wont have any effect (it is 'hop' based, not time based - with a hop being the passage through some routing device)
