Could you give some more information?
Is this a dialog box you are talking about, in which case did you create it using MFC, Class Wizard etc. and using the default id IDCANCEL for it?

Sounds weird then. Are you sure the OnCancel is being called by the spacebar action? I'd override it to double check. Are there any other buttons on the dialog? Are they similarly affected?

Is the mouse working at all in the rest of the dialog box? Could you try putting in, say, a radio button and seeing whether that works?

Well, I'm stating the b. obvious here, so apologies, but at least you've got the cancel button out of the equation! You could try GetCapture to see which window has the mouse capture, but other than that I'm all out of ideas, I'm afraid.

Strange that CFont::GetLogFont not const

really strange...
did I oversee something? Those WinAPI stuff confuses me sometimes... but i see no reason why it can't be const. I needed a const version so I did this:

// Get LOGFONT structure
BOOL CMyFonts::GetLogFont(const CFont& Font, LOGFONT* pLogFont) const
{
  ASSERT(pLogFont);
  HFONT hFont = Font;
  return ::GetObject(hFont, sizeof(LOGFONT), pLogFont);
}

Just look what I do. The important line can work on a const method! I am following Scott Meyers recommendations!

C++

CSomeClass& CSomeClass::operator=(const CSomeClass& source)
{
	m_name=source.m_name;

	LOGFONT lf;
	(const_cast<CFont&>(static_cast<const CFont&> (source.m_font)).GetLogFont(&lf)); //this is the important line
	m_font.Detach();
	m_font.CreateFontIndirect(&lf);

	//...

	return *this;
}

Superscipt in sourcecode/dialog caption

Hello,

I'm writing an application which displays physical units for velocity, density etc in a Dialog. Some require parts of the units to appear in superscript e.g. m/^s and kg/m^3.

I have access to some source code which contains the superscript characters for 1 ,2 , and 3, so I'm able to copy and paste these characters when I need them.

I now need the superscript for '4'. I'm hoping to avoid Unicode fonts for as long as possible. Can anybody help me?
Thanks,
John

If your app is a non-commercial one, GipsySoft's QHTM Ultra small Win32 HTML control[^] can be used for free and seems a good option.

You could write your own variant of CStatic which could display superscipt characters. When it comes to captions in dialogs take a look at customcaption.asp[^]. This oculd be adapted to draw superscipt characters as well.

MDI frame windows don't have active views. Instead, there's the CMDIChildWnd which has associated views. Thus you first need the active child window, then being able to get the active view:

CMDIChildWnd *pChild =
                  (CMDIChildWnd *) GetActiveFrame();

CMyView *pView = (CMyView *) pChild->GetActiveView();

Contrilling Smart App's from internal Web pages

Hi.

I am developing a Visual C++, MFC/ATL app. I have a HTML view so I can display HTML web pages which are stored in a CHM file or direct on disk. I want to be able to have a button on the web page which when pressed will call a function in my application. (Ie. Click Here to create a new document, File|New menu option)

If you look at Microsoft Help for active directory, you get pages where you can click on a button which will open the MMC for Users & Computers in Active Directory.

Does anyone have any Ideas how to do this?

Thanks.

Hello,
to call an application's function out of a html page, you should use the the external object provided in JavaScript. To be able to react on the fuction call, you've to implement the IDispatch interface in your application, there handling GetExternal(). This function is called whenever a call to external is done inside a web page.
To get more information, you should search MSDN for "webbrowser customization" or chtmlview and IDispatch.

Hi...i wanna to create many dialogs, each display chart control.They are modeless dialogs
i want to make a menu command the makes all the dialogs be cascaded or tiled.i can't make the dialogs in child style cz that makes them misdrawed

The code that i am using to generate the dialogs

void CDelete15View::OnDialogModeless() 
{
	// TODO: Add your command handler code here
	if (!modeless)
	{
		modeless=new CModeless (this);
		modeless->Create(IDD_DIALOG1,GetWindow(GW_HWNDFIRST));
	}
	modeless->ShowWindow(SW_SHOW);

	
	if (!p1)
	{
		p1=new CModeless (this);
		p1->Create(IDD_DIALOG1,GetWindow(GW_HWNDFIRST));
	}
	p1->ShowWindow(SW_SHOW);

	if (!p2)
	{
		p2=new CModeless (this);
		p2->Create(IDD_DIALOG1,GetWindow(GW_HWNDFIRST));
	}
	p2->ShowWindow(SW_SHOW);

	if (!p3)
	{
		p3=new CModeless (this);
		p3->Create(IDD_DIALOG1,GetWindow(GW_HWNDFIRST));
	}
	p3->ShowWindow(SW_SHOW);

	if (!p4)
	{
		p4=new CModeless (this);
		p4->Create(IDD_DIALOG1,GetWindow(GW_HWNDFIRST));
	}
	p4->ShowWindow(SW_SHOW);

	if (!p5)
	{
		p5=new CModeless (this);
		p5->Create(IDD_DIALOG1,GetWindow(GW_HWNDFIRST));
	}
	p5->ShowWindow(SW_SHOW);
	if (!p6)
	{
		p6=new CModeless (this);
		p6->Create(IDD_DIALOG1,GetWindow(GW_HWNDFIRST));
	}
	
	p6->ShowWindow(SW_SHOW);

all the dialog is pop style and thin frame style
