Hi
I have developed a dialogue based MFC application. On that dialogue I have used two ActiveX control called WebBrowserCtrl, Their IDs are as : IDC_EXPLOREER1 AND IDC_EXPLORER2.
I have declared it in my CWebBrowserDlg.h file as
CWebBrowser2 m_WebBrowserCtrl;
CWebBrowser2 m_WebBrowserCtrl2;
bool m_bWebBrowserCtrl;
Now what I want to do is when initially I load form It should show some site on it. Then after few seconds it should show another ActiveX control having different site loaded into it.
For this I have used OnTimer() function and have one boolean variable which i set to true and flase alternatively....
It works fine for the first time.....I mean first it shows content into IDC_EXPLORE1 then it shows Content into IDC_EXPLORER2 and after that it shows illegal error (Abort, Retry, Ignore) and on debuging it by pressing Retry button it takes me to following code in WINOCC.cpp file
Here it shows m_hWnd as NULL.
BOOL CWnd::ShowWindow(int nCmdShow)
{
ASSERT(::IsWindow(m_hWnd));
if (m_pCtrlSite == NULL)
return ::ShowWindow(m_hWnd, nCmdShow);
else
return m_pCtrlSite->ShowWindow(nCmdShow);
}
My code is as following.....
So for that I have written code like this :
//In WebBrowserDlg.cpp
BOOL CWebBrowserDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Add "About..." menu item to system menu.
// IDM_ABOUTBOX must be in the system command range.
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX < 0xF000);
CMenu* pSysMenu = GetSystemMenu(FALSE);
if (pSysMenu != NULL)
{
CString strAboutMenu;
strAboutMenu.LoadString(IDS_ABOUTBOX);
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
}
}
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon
//Set the timer so that after every 15 seconds it will call OnTimer function
m_nTimer = SetTimer(1, 15000, 0);
m_bWebBrowserCtrl = true;
// navigate to main web page, my favorite web page
m_WebBrowserCtrl.Navigate(m_Site, NULL, NULL, NULL, NULL);
m_WebBrowserCtrl2.Navigate("http://www.google.co.in/", NULL, NULL, NULL, NULL);
return TRUE; // return TRUE unless you set the focus to a control
}
void CWebBrowserDlg::OnTimer(UINT nIDEvent)
{
if (m_bWebBrowserCtrl == true)
{
m_WebBrowserCtrl.ShowWindow(SW_HIDE);
m_WebBrowserCtrl2.ShowWindow(SW_SHOW);
m_bWebBrowserCtrl = false; //I have forgotten to write this two
//sentence....where as actually it is in my code
}
else
{
m_WebBrowserCtrl.ShowWindow(SW_SHOW);
m_WebBrowserCtrl2.ShowWindow(SW_HIDE);
m_bWebBrowserCtrl = true;//I have forgotten to write this two
//sentence....where as actually it is in my code
}
}
Any help please....? Any other idea to show two control alternatively...

Just a thought...
In your OnTimer you probably need to toggle the m_bWebBrowserCtrl variable:
void CWebBrowserDlg::OnTimer(UINT nIDEvent)<br />
{<br />
if (m_bWebBrowserCtrl == true)<br />
{<br />
m_WebBrowserCtrl.ShowWindow(SW_HIDE); <br />
m_WebBrowserCtrl2.ShowWindow(SW_SHOW);<br />
}<br />
else<br />
{<br />
m_WebBrowserCtrl.ShowWindow(SW_SHOW);<br />
m_WebBrowserCtrl2.ShowWindow(SW_HIDE);<br />
}<br />
m_bWebBrowserCtrl = !m_bWebBrowserCtrl;<br />
}<br />
Without that, the second time in, the m_WebBrowserCtrl is already hidden.
Hope that helps.

I'm not sure if this is the reason for your problem, but shouldn't you put this statement last in your OnTimer()-funcion?
CDialog::OnTimer(nIDEvent);

Hi to all,
Can u help me in How to disable a Menu Item. i am trying this code but not getting.
CMenu menu;
menu = AfxGetMainWnd()->GetMenu();
menu->EnableMenuItem(ID,MF_BYCOMMAND|MF_DISABLED);
Urgent
bye

Not exactly sure what your issue is. Is it that your code does not compile (sorry, not sure if your new to c++ / mfc or if it's just a typo)?
If your code is not getting through a compile, try:
CMenu *menu = AfxGetMainWnd()->GetMenu();<br />
if (menu)<br />
menu->EnableMenuItem(ID,MF_BYCOMMAND|MF_DISABLED);
That should work fine.
Also, you can insert an update hander with MFC. In your message map, insert
<br />
BEGIN_MESSAGE_MAP(yourClassName, yourBaseClass)<br />
ON_UPDATE_COMMAND_UI(ID , OnUpdateMyMenu)
END_MESSAGE_MAP()
In your class definition insert
afx_msg void OnUpdateMyMenu(CCmdUI *pCMDUI)<br />
And the implementation:
void yourClassName::OnUpdateMyMenu(CCmdUI *pCmdUI)<br />
{<br />
pCmdUI->Enable(FALSE );<br />
}<br />

From MSDN (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_wcemfc4/html/aflrfcmenucolcolenablemenuitem.asp[^])
This method either enables or disables and dims a menu item.
UINT EnableMenuItem (
UINT nIDEnableItem,
UINT nEnable );
Parameters
nIDEnableItem
Specifies the menu item to be enabled, as determined by nEnable. This parameter can specify pop-up menu items as well as standard menu items.
nEnable
Specifies the action to take. It can be a combination of MF_DISABLED, MF_ENABLED, or MF_GRAYED, with MF_BYCOMMAND or MF_BYPOSITION. These values can be combined by using the bitwise OR operator. These values have the following meanings:
MF_BYCOMMAND Specifies that the parameter gives the command ID of the existing menu item. This is the default.
MF_BYPOSITION Specifies that the parameter gives the position of the existing menu item. The first item is at position zero.
MF_DISABLED Disables the menu item so that it cannot be selected but does not dim it.
MF_ENABLED Enables the menu item so that it can be selected and restores it from its dimmed state.
MF_GRAYED Disables the menu item so that it cannot be selected and dims it.
Return Value
Previous state (MF_DISABLED, MF_ENABLED, or MF_GRAYED) or –1 if not valid.
So, try MF_GRAYED. The the menu item will be both disabled and grayed.

 doh: I use WMI to set Ip Address for my local computer.
every function works well. but nothing changed.
Why?? I use vc6,xp OS. For some header files,you can found them from vc7, just copy them to the Include directory for vc6.
BSTR Path = SysAllocString(L"\\\\MyComputerName\\root\\cimv2");
for a test,the above line must be modified.replace "MyComputerName" with your own computer name.
I paste all the code here. A win32 console app.
Thank you everyone.

by writing a bit more clearly, more spaced... using <pre></pre> around your code why not ?!

Yes,you are right.
I have pasted the same qustion here for three time until now.

Hello Tcpip2005, How are you doing? when ever you are trying to copy code in code project, then just try to use html tags. like this.
< is used for less than symbol. = "<"
> is used for grater than symbol. = ">"
Then your code can be readable.
Or check the Check Box(Do not treat <'s as HTML tags) when ever you post question?
Nice talking to you.

Ok the situation is this, Im doing some applications , the first one is an application with 3 buttons that also has an Ip control with that application I put the Ip adress of the application (Server) that is an audio application that capture Audio.
with the first application (the one with the 3 buttons, starting, stoping and exit button, I send one character to the audio application)
I took one audio capture application from the codeproject to use it on my project, the problem is that I dont know how to put support to windows sockets, the audio application is made it in Visual C++ in a MFC, somebody knows how to paste the code to give support to the sockets.
something like the wizzard does when you are generating the MFC application that you can add support to 3d buttons, and sockets.
and also, somebofy knows about another audio capture application that I could use to my project.
another question that I have, if somebody can help me, is that Im just starting in the world of the code, and the POO,
so I need to take this data ( the buffer of the captured audio and send it through the socket, but I dont know how to do it.
can I use the function RECV(s2, &buffer,1,0)
where s2 is the socket that Im using, but I dont know what to put in the other params)
if somebody could help me,
GOD BLESS YOU
my email is
rubencia@yahoo.com
thanx again to everybody
