This is more of a design question. I have a CDialog derived window (several) and when I spawn them I push_back their pointers on a vector. This vector is externed so the CDialog guys can see it. Now when I right click on any one of these windows I need to get the pointer of the CDialog I had stored on the vector. How do I get this to happen? Alos when i right click on this control, I want a context menu (popupmenu) to materialize.
What is the difference between the handler written to capture WM_CONTEXTMENU and WM_RBUTTONDOWN - both operate on a right mouse click.....so if I write handlers for both messages which one runs?
Appreciate your help,

I wrote a CDialogManager class for this very purpose. (I don't have an article yet though.) Basically, what I do is put the vector of dialogs in their own wrapper class (CDialogManager in my case), and set up public methods to get at what I want. Then in your dialog that you want to access one of the ones in the vector, you merely do something like:
CMyDialog* pDialog = &MyManagerClass.GetDialog(iDialog);
Now, pDialog-> is ready to go.

So when I am right clicking the dialog, how does it know what the iDialog is to call GetDialog with? AM I missing something really obvious?

WM_RBUTTONDOWN is specifically for a mouse button click. WM_CONTEXTMENU is sent for a right-click, Shift+F10 keypress, or App key keypress (basically, any of the ways to get a context menu).

hi,
how to use CStdioFile to read separate lines from file like ifstream?
|
|
|
|
|
why do i get this message wenn i do this:
shutdown(sock, SD_BOTH);
my includes are:
#include "stdafx.h"
#include "stdio.h"
#include "tchar.h"
#include "process.h"
#include "crtdbg.h"
|
|
|
|
|
hello
you can try
"#include winsock2.h"
i hope that help you
|
|
|
|
|
lol,
thnx
|
|
|
|
|
I think you need to link with ws2_32.lib
You may need winsock2.h also, but I'm not sure.

Maybe #include winsock2.h will do the trick?
There is shutdown declared, according to MSDN.
My opinions may have changed, but not the fact that I am right.
|
|
|
|
|
This is oddly missing from winsock.h, use this instead:
shutdown(sock, 2);

You past the wrong parameter to shutdown().
shutdown(theSocket, SB_BOTH);

Hello,
I am posting here, because although the Problem refers XML, DOM and the MSXML2 Parser, i am using C++ to access the COM functions of the Parser.
After searching for simmilar thread - posts I finally did not find a solution for my problem ... although the topic was still discussed.
Is there any possibility to convert an IXMLDOMNodePtr into a IXMLDOMElementPtr ???
I know the IXMLDOMElement Object extends the IXMLDOMNode one. But because of the fact that I use the smart - pointers to the Interface Objects a downcast does not function. ( i think it is because of this )
All I want to do is just to call the IXMLDOMElement's method
' GetElementsByTagName("...") ' which unfortunatelly returns a List of Nodes ( IXMLDOMNodeList ) and not of Elements. After iterating the List a want to convert every Node of it an a IXMLDOMElement ...
Any Idea ???
Thank you in advance

Any ideas about an app that can detect if connected to the intertet???
I wrote a function that does it well, but I want to build a process that runs at background, and every time that I connect to the internet, it will signal me somehow.
Should I use some kind of a timer that checks connection every 'x' seconds, or there is some global object (HANDLE) that I can use a wait function on it?
Any suggestion will be blessed!

If you're only interested in connections established by use of RAS, then the RasConnectionNotification will work. It provides you a handle to an event object to be used in any wait function.

Hello!
I have a strange problem. I have a standard SDI - FormView application. On the form I have two check boxes (which I have set to buttons), they are called IDC_AUTOMAT and IDC_MANUAL. I have used DDX to handle the events(created with ClassWizard), OnAutomat() and OnManual().
My problem is that if I have IDC_MANUEL checked and minimizes the application and then restore it. Somehow the OnAutomat is called. I can't figure out where this happens and how I avoid it?
Please help!
Below is the call stack when I set a breakpoint in OnAutomat().

Have you checked that the IDC_xx values don't conflict with any standard Windows IDC_xx values. I assume the CWnd::OnSysCommand() is a Restore or Maximize command. Then you get OnSetFocus() which is fine. But why are you then getting OnCommand(). Have any of the controls been disabled.

Hello Neville!
Thanks for your answer!
I recieved an answer from an another source and the problem seems to be with the checkboxes and tab order. If I have the check boxes as the first tabs, i.e. The IDC_AUTOMATIC is tab 1 and therefore default focused. It will generate an ON_COMMAND IDC_AUTOMATIC. If I change tab order and let an editbox get the first tab then everything is OK!

This doesn't make any sense to me. You should see an ON_SETFOCUS but not an ON_COMMAND. It sounds like someone is sending an ON_COMMAND when they shouldn't be. Do you do any SendMessage( .., WM_COMMAND, .. ) in your code.
Also I'd suggest you use Spy++ or WinsSpector and look at precisely what messages the IDC_AUTOMATIC checkbox is getting.

No, I don't use SendMessage(). All message handlers are created with ClassWizard.
Also I'd suggest you use Spy++ or WinsSpector and look at precisely what messages the IDC_AUTOMATIC checkbox is getting.
I will try this, although since the program now works it's nothing I will prioritize
Thanks for your answer, I appriaciate it very much!
