My problem is that when i rotate my multiline text 180 degrees , the text is rotated but the ordering of lines in the text is wrong as the first line comes as last and last line comes as first(for eg. if i have two lines line1 & line2 then after rotation line2 is displayed and below it line1 is diaplayed).I have passed the DT_WORDBREAK as parameter to the CDC drawtext function to handle word wrapping.
Is ther any other way to handle rotation of multiline text?
Kindly let me know

The following example shows how to rotate text at any angle (doesn't work on 95/98/ME). It renders text at (50, 50) rotated 30 degress clockwise.
--------------------------------------
CPaintDC dc(this);
int OldMode = SetGraphicsMode(dc.m_hDC, GM_ADVANCED);
static const double pi = 4.0*atan(1.0);
static const double angle = 30.0*(pi/180.0);
static const XFORM xf = {cos(angle), sin(angle),
-sin(angle), cos(angle),
0, 0};
SetWorldTransform(dc.m_hDC, &xf);
CRect rcClient;
GetClientRect(&rcClient);
rcClient += CPoint(50, 50);
dc.DrawText(_T("Hello\nThere"), -1, &rcClient, 0);
SetGraphicsMode(dc.m_hDC, OldMode);

You have to use ownerdraw...

Hi rahul.shendurnikar,
You can use derived CButton and use WM_DRAWITEM in class

Hi all,
I have a CTreeCtrl as a child of a docking window (CMyBar). In my docking window class I set a handle just like this:
(
CMyBar.cpp)<br />
ON_NOTIFY(TVN_SELCHANGED, ID_TREE, OnTreeChange) ...<br />
The declaration of the function is
(CMyBar.h)<br />
afx_msg void CMyBar::OnTreeChange(NMHDR *hdr, LRESULT *NotUsed)<br />
I had to explicity add the ON_NOTIFY handler because the Visual Studio6 ClassWizard doesn't show the ON_NOTIFY event for my docking class (CMyBar), (don't know why?).
As far as I know CTreeCtrl does send ON_NOTIFY notifications to it's parent (CMyBar). Spying++ CMyBar window class shows CMyBar gets WM_NOTIFY messages...
Now all this crap doesn't work (OnTreeChange never gets called), and I'm to figure out what's going on and what's wrong with it.
Would be really happy if someone can answer this question...
Thank you!

try to look with spy on the Tree Control properties, perhaps it has a flag indicating not sending a parent notify (WM_PARENTNOTIFY).....in my code the selchange does call the parent notification and the method OnTreeChange does get called....
hope this helps

Hi Yaron,
Thanks for the reply... But the problem is my parent window (CMyBar) does get WM_NOTIFY and VM_PARENTNOTIFY messages(I've checked it with Spy), but my method OnTreeChange never gets called...
I'm new to MFC and I'm sure I'm missing something here.

well, if you have checked it with spy and the Bar does get the WM_NOTIFY message, then check the id of the tree control (IDC_TREE) check the name of the function.....other than that it suppose to work....

Thanks for your help! You're right, it was a an incorrect id of the tree control.

hi all,
i am unable to access the property page control values from another property page.
// snippet of the code
CPropertySheet dlg(_T("Hellow"), this, 0);
one a; //First Property Page
two b; //second Property Page
three c; //third Property Page
dlg.AddPage(&a);
dlg.AddPage(&b);
dlg.AddPage(&c);
dlg.SetWizardMode();
dlg.DoModal();
//================================================
if the first property page contains the ComboBox with some values i am trying to acces the values in the second property page as
one* m_Main2 = (one *) GetParent();
CString str;
for(int i =0;i< m_Main2->p->GetCount();i++)
{
m_Main2->p->GetLBText(i,str); // p is the pointer of the combobox
MessageBox(str);
}
where p is the pointer of combobox control in the first property sheet.
any solutions for this please.
thanks
uday.

The dialog of property will be created only if it is shown once. That is why you can't access them.

As each tab loses focus, store the control's values in the sheet (parent).
