CFormView without Doc

VC++ 6 with AppWizard DocView disabled, how does one open/activate a view based on CFormView as the result of some user action? The view will display/accept data to be used with an ADO data source.

I can add the form/view to the project source, but can not open the view at the appropriate time.

Thanks,

Maximize Window

I have a SDI MFC application using CFormView dialogs. The stupid frame is always the same size when I open the application. What's the best way for me to make the application maximize on the screen? When I've tried to ShowWindow( SW_MAXIMIZE ); it seems to just ignore it. Thanks a bunch! Poke tongue | ;-P

So do you have a call to ShowWindow(SW_MAXIMIZE) in your app's InitInstance() method?

Ok, I can maximize the window doing this in the InitInstance() method, but this poses another problem. In my view's OnInitialUpdate() function I position some windows in my dialog (texts, buttons, etc). I use the size of the window to center these, but when I maximize the window, the windows aren't centered correctly, is there another way to maximize the frame, before I have to initialize my views, so that their client coordinates match up with what I'm actually going to use? Should I be arranging their positions in a different function instead?

Invert Pen/Line?

Hi all,

I have searched several places including message boards and Google, without any result! Have I missed something or am I the first to ask regarding this:

How can I create, or get an already available, invert pen? Which when used for drawing (ex. lines) it inverts all pixel colors it comes in “touch” with. I am not looking for the DrawFocusRect function, but a pen or function that draws an invert line.

Once you get a pointer or handle to a device context, call SetROP2 and pass in R2_NOT as the drawmode.

Could someone please let me know how I can get my CDHTMLDialog to scroll. I have tried "scroll = yes" in the Body tag of the html and setting the scrollbars in the dialog editor itself but niether seems to work. I have another app that scrolls just fine but his one will not cooperate. Any ideas. This must be a common newbie question Blush | :O

What the heck is this and why did it fix my problem?

SetHostFlags(DOCHOSTUIFLAG_NO3DBORDER);//enables scrolling???
CDHtmlDialog::OnInitDialog();

CDHtmlDialog::OnInitDialog() calls
SetHostFlags(DOCHOSTUIFLAG_NO3DBORDER | DOCHOSTUIFLAG_SCROLL_NO).
Your call clears DOCHOSTUIFLAG_SCROLL_NO flag and enables scroll bars.

Ok help me out here now ;>

First of all this is only a thought i had and if you think it's totaly stupid, please do say so if you wish :P

Ok, here is the deal.. Im planing on making a type of resource manager, all "resources" should inherit by a class "Resource" that also takes an templated argument for a type...

template <class Type>
class Resource
{
private:
Type *m_Res;

public:
Resource();
virtual ~Resource();

virtual Type * GetResource() { };
virtual operator=(const Type &t) { };
}; // Etc etc

And thus enabling the user to still overload everything given by the base class if it's need for it, so for a texture for instance.

class Texture : Resource<IDirect3DTexture9>
{
public:
int Width;
int Height;
// Etc...
private:
bool Load(string);
// and all the stuff connected to it.
};

and a material

class Material : Resource<D3DMATERIAL9>
{
private:
// lots of strange stuff
public:
// same here
};

So far, i like the model and how i can use it for most stuff that i could call a resource... but here comes the problem, as its templated i cant use the class "Resource" as a "base" class for casting, so in the resource manager i cant just make a std::list<Resource> l; and then push back whatever that comes from resource.

ex:

class ResourceManager
{
private:
std::list<Resource *> m_ResList;
public:
bool Add(Resource *res) {
m_ResList.push_back(res);
}
};

If anyone even takes time to read this post i am soooo wanting ideas about this. Anyone want to help making it maybe better? .. A better way to make it? .. want me to throw it out the window . .whatever as long as you understand what i want to make you are welcome to reply Poke tongue | ;-P

(Tired and dont even know how all that came out, if to many dont understand it just ignore it later Poke tongue | ;-P

... I hope someone does tho Poke tongue | ;-P

UpdateData into modeless dialog?

andrzejf13-Oct-03 8:34

andrzejf

13-Oct-03 8:34

Could anybody explain me, any example very welcome:

I create modeless dialog, as follows:
in myTabControl.cpp // The source code for this class I downloaded from code guru page

void CMyTabControl::Init() // CMyTabControl is derived from CTabCtrl<br />
{<br />
	m_tabCurrent=0;<br />
          // CDialog *m_tabPages[2];<br />
	m_tabPages[0]->Create(IDD_DLG_TAB1, this);<br />
	m_tabPages[1]->Create(IDD_DLG_TAB2, this);<br />
	<br />
	m_tabPages[0]->ShowWindow(SW_SHOW);<br />
	m_tabPages[1]->ShowWindow(SW_HIDE);<br />
	SetRectangle();<br />
}

I call Init() function in:
In Stp2View.cpp

void CStp2View::OnInitialUpdate() // CStp2View is derived from CFormView<br />
{<br />
	CFormView::OnInitialUpdate();<br />
	GetParentFrame()->RecalcLayout();<br />
	ResizeParentToFit();<br />
<br />
	m_tab.InsertItem(0, _T("Table1"));  // m_tab is CMyTabControl member var.<br />
	m_tab.InsertItem(1, _T("Table2"));<br />
	<br />
	m_tab.Init();<br />
}

My question is:
how can I update data in IDD_DLG_TAB1 Form, for example
in Stp2View.cpp

void CStp2View::OnMoveToNextRecord()<br />
{<br />
   .....<br />
   CString str = "test update data";<br />
   UpdateData(TRUE);  // in this line is    Assertion   <br />
ASSERT(::IsWindow(m_hWnd));  //calling UpdateData before DoModal"?<br />
  ....<br />
// I tried<br />
((CDlgTab1*)tab.m_tabPages[0])->UpdateData(FALSE)  // the same Assertion<br />
}

Thanks a lot ...

Trapping KeyBoard events

I found that i need to override PreTranslateMessage to trap events .

if(pMsg->message==WM_KEYUP ){
CString text;
text.Format("Key params %d ",pMsg->wParam);
AfxMessageBox(text);
return true;
}

I need to trap a sequence of ALT-CTRL-E ? How can I do this ?

If you're looking for all 3 keys to held down at the same time, just look for one of them (like "E") with PreTranslateMessage, then check keystate of others with GetAsyncKeyState. VK_CONTROL is virtkey for Ctrl, and VK_MENU is virtkey for Alt.

I have a number of modeless dialog in my MDI applicaion.
When I try to open multiple dialogs and close, sometimes
the application fails. what is the proper way to close a
modeless dialog if I open the dialog like the following.
at the moment I make another function in dialog class called
closedialog and call protected function OnClose() any I was
thinking of deleting the pointer that was new at the top of
line. I am not 100% sure about it.

Any help is appliciated.

if( ! p_MyModelessDlg )
{
p_MyModelessDlg = new CMyModelessDlg;
}

if( pDoc -> b_Data == TRUE )
{
if (!::IsWindow( p_MyModelessDlg -> GetSafeHwnd() ) )
{
p_MyModelessDlg -> Create(IDD_MYMODELESS, this);
}
p_MyModelessDlg -> GetData();
p_MyModelessDlg -> ShowWindow(SW_SHOW);
p_MyModelessDlg -> b_OpenStatus = TRUE;
}

You need to override the beahviour of the PostNcDestroy() - in this method
FIRST call the super classes' PostNcDestroy()
and then

delete this;

You may need some way to tell your app the dialog is closed (you might put this in your PostNcDestroy impl.
