Hello,
i've a problem with a subclassed CEdit on WindowsCE 5.0.
If i use SetPasswordChar and SetFont in the same subclassed CEdit it generates an acces violation
[Stack fault]: Thread=9a431400 Proc=98328d20 'xxxxxx.exe'
AKY=00004001 PC=0017ba6c(xxxxxx.exe+0x0016ba6c) RA=000318e8(xxxxxx.exe+0x000218e8) BVA=1e2a1ee4 FSR=00000007
my Code:
...
if(edit->SubclassDlgItem(IDC_EDIT1, this)){
edit->SetFont(m_Font, FALSE);
edit->SetPasswordChar(0x25CF); // --> stack fault
}
...
If i don't use SetFont OR SetPasswordChar it works fine...
whats wrong ???
can anybody help me?
Thanx for replys...
edit:
// Initialization
Controls.edit2 = new CMyEdit();
Controls.edit2->__SubClassControl(this, IDC_EDIT2);
Controls.edit2->__SetMaxTextLength(9);
//Controls.edit2->SetPasswordChar('*'); // --> stack fault
Controls.edit2->SetPasswordChar(0x25CF); // --> stack fault
// Control-Code
BOOL CMyEdit::__SubClassControl(CMyDialog *pParent, int nID)
{
// subclassing per SubclassDlgItem is okay, SubclassWindow does not work
m_pParent = pParent;
m_nID = nID;
BOOL ret = SubclassDlgItem(m_nID, m_pParent);
// changing FontSize to parentfont and the heigth of the Control
LOGFONT lf;
if(m_pParent->GetFont()->GetLogFont(&lf) != 0){
// m_Font is a derived class from CFont and an Item of my CMyEdit for better Fonthandling
// if i use CFont the same Problem exist with SetPasswordChar (isn't the reason)
m_Font->_SetLogFont(lf);
if(m_bFontResizing == TRUE){
CRect rect;
GetClientRect(&rect);
rect.DeflateRect(2,2,2,2);
m_Font->_SetHeight(rect.Height());
}
SetFont((CFont*)m_Font, FALSE);
}
return ret;
}
void CMyEdit::__SetMaxTextLength(int maxLen)
{
m_maxLen = maxLen;
// del mask
m_Mask = _T("");
}

No real idea here but what happens if you change the order, use SetPasswordChar first and then use SetFont? Any change?

i try it, but it has no effect...
the message EM_SETPASSWORDCHAR raises the error, mfc is not the reason...
|

So let me get this clear:
edit.SetFont(somefont);
edit.SetPasswordChar(whatever); <- it crashes here
crashes and
edit.SetPasswordChar(whatever); <- it crashes here again, so SetFont never gets called
edit.SetFont(somefont);
crashes too but
edit.SetPasswordChar(whatever); <- works ok, no SetFont around
works. That is very strange, i don't really see the great difference between the later two cases since SetFont never gets called at all in either case.

not directly...
edit.SetFont(somefont);
edit.SetPasswordChar(whatever); <- it crashes here
edit.SetPasswordChar(whatever);
edit.SetFont(somefont);<- it crashes here
edit.SetPasswordChar(whatever); <- works ok, no SetFont around
i check now if the subclassing is the reason...
wait a moment...

Ah, i see. Where do you perform all this? I mean, the subclassinc of the edit and the rest? I mean, in what method, at what event...?

in OnInitDialog...
i've rewritten a little class to encapsulate this problem, it looks like a WindowsCE-Problem...
in Win32 works fine...
edit:
give up...
in pocketpc-emulator it works always fine :-|
it must be devicedependend or a devicemistake...

If your edit control is set to multiline, that could be the problem. MSDN states that SetPasswordChar is not supported on multi-line edit controls.

MSDN says the Function has on effect in multineedit...
i test it...
edit: tested, but no effect

Here's a quote from MSDN:
Remarks
When a password character is set, that character is displayed for each character the user types.
This member function has no effect on a multiple-line edit control.
When the SetPasswordChar member function is called, CEdit will redraw all visible characters using the character specified by ch.
If the edit control is created with the ES_PASSWORD style, the default password character is set to an asterisk (*). This style is removed if SetPasswordChar is called with ch set to 0.
For more information, see EM_SETPASSWORDCHAR in the Platform SDK.

I'm not sure how Windows CE treats char. But try using some simple char like '*' first.
|
|
|
|
|
has no effect - SetPasswordChar requieres a TCHAR as parameter
|
|
|
|
|
Windows CE only supports Unicode.
So all string MUST be L"" and all characters are 2 bytes.

i know...
0x25CF are 2 bytes, or not?
ans strings with L"" or _T("") or TEXT("")...
there is a single Character as parameter required in TCHAR-Format...
the app works in emulator, it must be devicedependend...
on an other device the app has no problem and works...
thanx

Since the edit control is just going to show a * anyway, why does it need a different font?

i change the fontsize to fit in the control...

i change the fontsize to fit in the control...
e.g. from size 8 to 15 - and the oher edit controls have size 15
looks not so fine, if the passwordcontrol has only size 8
if i use '*' as default, the access violation occurs if i set a new font.
if the flag ES_PASSWORD or a PassworChar is set and i try to set a new font the access violation is always generated...
i have no idea...

Using CHeaderCtrl and ClistCtrl, I am displaying some data in a grid format.
But while moving the horizontal scroll bar the header data is not displaying.But data in the grid is displaying.
Is there is any method to refresh the header data while scrolling.
Please help..
Regards

Did you maybe set the WS_CLIPCHILDREN style on the list control? I have seen that resulting in the header not getting drawn in various situations. Anyways, you could try subclassing your list, handling WM_HSCROLL, relaying it to the superclass and then invalidating the header control, maybe it helps, but imho your header should get displayed by default if you do scrolling, so there must be something influencing the workings of the list control.

The 1st is with setsockopt, and the 2nd is with Ioctlsocket.
Have they to be consistent?
