hey, i started building my app in VC++6 and i want to access an IE window's javascript to retrieve the contents of an HTML input box. how can i do that? can you post a sample script?
|
|
|
|
|
I created an own MFC web browser, fetched some interfaces to MSHTML and retrieved the contents that way.
Maybe there is also a way to get the MSHTML interface by injecting a DLL or by creating a toolbar...
Don't try it, just do it!

I hear there's a simple way to do it using DOM, but how?

 I have an MFC application based on Document/View Architecture which is also an MDI application. I am able to add ToolBar and StatusBar in MDI Child window but instead I need to add menu to MDI child windows. Is there any trick available to add menu in MDI Child window? Per MSDN, MDI Child window can not have its own menu. Please help.

I can replace the floating frame class in my application with my own ( derived class from CMiniDockFrameWnd )
by using something like :
m_pFloatingFrameClass = RUNTIME_CLASS(MyMiniFrame);
but it replaces all the floating frames for the application ( toolbars, floating windows, ... )
Is there a way to have a different class for each toolbar ( for example ) so that I can do something special for each ?
I'm trying to set a minimum size on the floating window with OnGetMinMaxInfo, but when doing so, it also set the size for the toolbars ( when floating ) and do it will create a frame that is larger than the actual size of the toolbar.
Thanks.
Max.

I have created a modeless dialog. I am passing in the pointer to the parent window - which happens to be a CFormView derived class.
m_pModeless = new CModelessDialogHeap(this);
Now when I want to get the parent pointer (m_pModeless) from the modeless dialog I can do two things. A. Store the pointer passed into the constructor of the modeless dialog and use that -- which works.
B. Or, according to one article on this site "http://thecodeproject.com/dialog/gettingmodeless.asp" I should be able to use GetParent().
When I do, it doesn't. It returns an empty pointer
CWnd * tmpPtr = this->GetParent();
What am I missing? Thanks!

Sorry I dont' know what you mean. The dialog is created via clicking a button on a CFormView derived class and its pointer (this) is passed to the Modeless Dialog constructor.

a window's parent is set by the code that creates the window (in the case of a modeless dialog, that's generally your code). if you don't set a parent wnd (usually in the dlg ctor, or in Create) it will remain NULL.

Look at my first post. I am setting the parent window to the dialog.
Please give me an example if I am off base.
|
|
|

Here is the code that creates the modeless dialog box
void CFormsFormsFormsView::OnModelessheap() {
if(m_pModeless){
m_pModeless->SetForegroundWindow();
m_pModeless->CenterWindow();
}
else {
m_pModeless = new CModelessDialogHeap(this);
m_pModeless->Create(CModelessDialogHeap::IDD);
m_pModeless->CenterWindow();
m_pModeless->ShowWindow(SW_SHOW);
}
}
It all works fine. I just don't understand why GetParent() doesn't when called from the modeless dialog box.
Thanks

can you step into that Create call ?
i suspect some other bit of code somewhere is setting the dlg's m_pParentWnd to NULL. Create is another common place to set that variable.

Yes I've stepped through the code. Like I said, the parent is passed into it just fine because I can assign that pointer to a member variable.
But GetParent() should do the same thing...right?
Appreciate your help. Here is the code
CModelessDialogHeap::CModelessDialogHeap(CWnd* pParent /*=NULL*/)
: CDialog(CModelessDialogHeap::IDD, pParent)
{
//{{AFX_DATA_INIT(CModelessDialogHeap)
// NOTE: the ClassWizard will add member initialization here
//}}AFX_DATA_INIT
m_parent=pParent;
}

The only thing I do different for my modeless dialogs is to call Create(IDD) from within the dialog's constructor.
Does commenting out the call to CenterWindow() have any effect?

I've tried this several different ways and it works fine each time (i.e., GetParent() returns the correct value). What does the constructor of CModelessDialogHeap look like? From where are you calling GetParent()? Is CModelessDialogHeap derived from CDialog?

I sent the constructor of CModelessDialogHeap already. Here it is again.
CModelessDialogHeap::CModelessDialogHeap(CWnd* pParent /*=NULL*/)
: CDialog(CModelessDialogHeap::IDD, pParent)
{
//{{AFX_DATA_INIT(CModelessDialogHeap)
// NOTE: the ClassWizard will add member initialization here
//}}AFX_DATA_INIT
m_parent=pParent;
}
CModelessDialogHeap is derived from CDialog.
As long as the parent exists it shouldn't matter where GetParent is called. But I put a button on the dialog and attempted it while it was still active.
void CModelessDialogHeap::OnButton1()
{
CWnd * tmpPtr = this->GetParent();
}
Thanks for your help as well David.

At this point my suggestion would be to create a little dialog-based test application that does nothing but create and show a modeless dialog in the OnInitDialog() method. Let me know how that works out.

Okay I created a dialog based app and the GetParent function works as advertised. So now we know that the problem is more likely a conceptual one. The mainApp dialog is a popup and the CDialog derived modeless dialog is also a popup. Code is exactly the same as the problem project.
In the problem project example I couldn't get to work I had an MDI application that had a CFormView derived class. It was a child. That child had a button when pressed would create the CDialog derived class modeless dialog. The CDialog derived class was set as PopUp. So can't a child spawn a modeless dialog (works) and can't that dialog in turn know it's spawning entity as Parent (GetParent).
I won't mention anything about child as it was demonstrated to me by David that a modeless dialog shouldn't have a child style. I agree.
I think this is important because these are pretty basic concepts.
Thanks for your help.

if youwant show a bimap file , you can use CImage Class.

if you want show a bitmap file ,like c:\\ff.bmp, you can use CImage MFC Class(VC++7 ).

What's this? MAKEINTRESOURCE() does not take a string for its argument.
In the project's resource.h file:
#define IDC_MYBITMAP 1234 // or some other appropriate value In the project's .rc file:
IDC_MYBITMAP BITMAP DISCARDABLE "c:\\ff.bmp" In the .cpp file:
HBITMAP hBitmap = LoadBitmap(NULL, MAKEINTRESOURCE(IDC_MYBITMAP));
if (NULL == hBitmap)
AfxMessageBox("LoadBitmap() failed.");
else
m_pic.SetBitmap(hBitmap);

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.
