As an FYI, my solution is to keep the C version. Why change what works?

Window handles and pointer values

prithaa6-Mar-07 20:32

Hello,

Suppose I am looking at the value of a pointer say
CView* ptr;
In the watch window when I debug, I get the value of ptr as

ptr 0x00326764 View hWnd 0x00000000

so does that mean, that a handle has not got its value as yet for CView pointer since the value of handle is 0 and that in future the handle will not function.

Does NULL value for handle indicate something ?

Correct me if I am wrong.

It means window is not created for CView object you are talking about.
This handle is generally initialized by call to Create.

Question about MFC Extesion DLL?

Dear All,

I am working with MFC Extension dll. I have two dialogboxes ( Main and Sub Dialog). The Main Dialog is present in an exe. This Main dialog calls sub dialog that resides in a MFC Extension dll. This sub dialog has few controls like buttons and listcontrol, its corresponding eventshandlers and classes.

At Execution, When i click on any control of sub dailog , eventhandlers are not coming up.

Why ? What could be the problem ?

Thanks.

I havn't done that .. but you can try Subclass WndProc in the SubDialog and try to see message routing

The two must use the same scheme for linking MFC. If the EXE statically links to MFC and the extension DLL dynamically links to MFC, that could be your problem.

Make sure the subdialog, from the extension DLL, has the main dialog as its parent and was not created with 'no parent'.

I am a beginner in using a list control. Could someone direct me in how to set the color of the cells (I hope this is the correct terminology) containing the column names in the list control, as well, setting the color of the first cell in each row. The color will be blue.

Thanks

I think you need to use custom draw . Refer this article by Michael Dunn[^].

In my sdi application i have made a splitter control which is dividing my frame in 2 parts(vertically).Now what i want to do is, when i click on a button in my toolbar i want that splitter control to be removed n a simple sdi window to come as it comes when we initially create as sdi frame....

It's actually rather simple. I've done exaclty what you're looking for by creating my own CSplitterWnd derived class. You can do something like this:

void CMySplitterWnd::ShowViews(bool bShowView1, bool bShowView2)
{
	ASSERT(bShowView1 || bShowView2); // We need at least one

	int nViewCount = 0;
	if (bShowView1)
		nViewCount++;
	if (bShowView2)
		nViewCount++;

	// Set the new number of columns in our splitter
	m_nCols = m_nMaxCols = nViewCount;

	// Save sizes for later
	CRect rc;
	m_pView1->GetWindowRect(&rc);
	m_sizeView1 = rc.Size();
	m_pView2->GetWindowRect(&rc);
	m_sizeView2 = rc.Size();

	int nMyViewCount = 2;
	// move pane ids
	m_pView1->SetDlgCtrlID(AFX_IDW_PANE_FIRST + nMyViewCount++);
	m_pView2->SetDlgCtrlID(AFX_IDW_PANE_FIRST + nMyViewCount++);

	int nCount = 0;
	if (bShowView1)
	{
		m_pView1->SetDlgCtrlID(AFX_IDW_PANE_FIRST + nCount);
		m_pView1->ShowWindow(SW_SHOW);
		SetColumnInfo(nCount, m_sizeView1.cx, 0);
		nCount++;
	}
	else
		m_pView1->ShowWindow(SW_HIDE);

	if (bShowView2)
	{
		m_pView2->SetDlgCtrlID(AFX_IDW_PANE_FIRST + nCount);
		m_pView2->ShowWindow(SW_SHOW);
		SetColumnInfo(nCount, m_sizeView2.cx, 0);
		nCount++;
	}
	else
		m_pView2->ShowWindow(SW_HIDE);

	RecalcLayout();
}

I have just designed a look alike RADAR display for which, i have used a static text box as the canvass I have drawn a circle with a line going round at the rate of 1.5 seconds per rev.
Now i have to plot points on this circle.

I have 2 problems
1> My display flickers with every rev of the needle
2> I have used Mapping mode- MM_ISOTROPIC but i am unable to understand how to convert points to the disagram(circle which is the radar display Sigh | :sigh:

Are you using CTabCtrl in conjunction with a property sheet? if yes, it would go very ease to do what you want to.

I think ,you are using property pages. Why do you need next button , if you can go to required tab by clicking it.
Next button are appropriate of wizard like property sheets.

Even though you need it, have a look at CPropertySheet::SetActivePage.

void CMyPage::OnClickNext()
{
((CPropertySheet*)GetParent())->SetActivePage(iIndexOfNextPage);
}
