Changing "SecureString" to "SecString" resolved the issue...

Change SecureString(char* s) to SecureString(const char* s) - there's no reason to not have the param be const. Then make the same change in the corresponding operator=

Hi Mike,

Thanks, but no joy...

I've since tried forcing the "\TP" switch, breaking out the *.h file into a 'h' and 'cpp' file, etc. I also made it a basic class (no inheritance). I've got the damn thing reduced to a class with 1 ctor - the char*. It's also broken for me (or more correctly, I'm doing something wrong) with VS 8.0 - previous was 7.0.

I alsoe get missing return type with ctor: SercureString( const char* s );.

Is the name "SecureString" used by VS? Earlier this week I installed the DDK. Could this be it???

Jeff

#pragma once
class SecureString
{

public:

    SercureString( const char* s );
    ~SecureString( );

private:

    SecureString();
};

SecureString::SecureString( const char* s )
{
    // assign( s, std::char_traits<char>::length( s ) );
}

Before you settle with SecString, please be aware that your original code had a mispelling at the char * constructor, you wrote SercureString rather than SecureString. Could it be this was the problem in the first place?

Problem in Creating Activex in AtlComponent

narayanagvs24-Jan-07 17:25

narayanagvs

24-Jan-07 17:25

Hi,

I have an Atl Component with an Interface EFCMyForm .(ATL Simple Object -- VS2005)
And a Dialog class CMydialog with ActiveX controls Placed on it. using right Click on Dialog and Insert ActiveX Control

In One of thw Exposed Method I am creating the dialog box CMyDialog

CMydialog g_myDlg;  // Global variable
STDMETHODIMP CEFCMyForm::Create() 
{
#ifdef _AFXDLL	
	AFX_MANAGE_STATE(AfxGetStaticModuleState())
#endif
    g_myDlg.Create(IDD_MY_DLG);
}

If I take a Global variable I don't have any problem but if I take mydialog obj as member variable as shown below...

CMydialog m_myDlg;  // member variable
STDMETHODIMP CEFCMyForm::Create() 
{
#ifdef _AFXDLL	
	AFX_MANAGE_STATE(AfxGetStaticModuleState())
#endif
   m_myDlg.Create(IDD_MY_DLG);
}

then the ActiveX Controls which are placed on the Dialog are not being Shown.

To resolve this If I try to Dyanamically create the ActiveX controls

CMyDialog::OninitDialog(){-----Using Create Control------           CLSID clsid;
		HRESULT hr1 = CLSIDFromProgID(OLESTR("EsdGraphCtrl.EsdGraphControl.3.0"),&clsid)	;
if (FAILED(hr1))		{		return FALSE;		}
BOOL blnSuccess;		CRect rc;		rc.left=0;		rc.top=0;		rc.right= 100;		rc.bottom =100;
blnSuccess = m_AxGraphControl.CreateControl(clsid,_T("Graph"),WS_VISIBLE|WS_CHILD,rc,this,100,0,0,0);
// Then  it is Resulting in Assertion in the above line
if (!blnSuccess)		
{		return FALSE;		}
}

Any Suggestions would be helpful

Thanks

ATL Object having event

Hi,

I want to write an activeX control that allows an event to be processed in the container class itself.

So what I want to do is have the ActiveX Control trigger say a Visual Basic Application when data is available. I am looking at ATL to write this, and I was wondering if this is possible with ATL.

If it is, does someone have some simple same code or something to assist me, I am brand new to ATL.

Thanks in advance for any help.

Absolutely.
Have a look at ATL examples in MSDN here[^] and as always; CodeProject is a good place to start, e.g. this article[^].
You might also want to browse through the other CP articles in the COM section[^].

I can't see ListView Control.what's the problem ?

shuaicarr23-Jan-07 14:39

23-Jan-07 14:39

step 1 : define a class "CMyListViewImpl ".
typedef CWinTraitsOR "WS_BORDER | LVS_REPORT | LVS_SINGLESEL |
LVS_NOSORTHEADER | LVS_SHOWSELALWAYS" CListTraits;
class CMyListViewImpl :
public CWindowImpl "CMyListViewImpl,CListViewCtrl,CListTraits"
//(here " is supposed to "<" and ">", web page can't show "< >" ,
//so i write " after CWindowImpl and CWinTraitsOR )
{
...
};
step2 : in SDI CMainFrame. define a data member "CMyListViewImpl m_list;"

step3 : create listview control :
CMainFrame::OnCreate()
{
...
m_list.Create(m_hWnd,rcDefault);
m_list.InsertColumn ( 0, _T("Macro"), LVCFMT_LEFT, 120, -1 );
m_list.InsertColumn ( 1, _T("Result"), LVCFMT_LEFT, 90, -1 );
m_list.InsertItem(0,_T("1"));
m_list.SetItemText(0,1,_T("D"));
m_hWndClient = m_list ;
}
the creation procedure are listed above,but i can't see the listview .where the bug lies ?(WTL 7.1 ,vc6 Cry | :((

The WS_VISIBLE style might help to see the listview, and the WS_CHILD to position it in the frame.
CMainFrame::UpdateLayout() should be called after m_hWndClient setting.

Hello everybody.

I get the following errors when compiling a small dialog app. I am using WTL 8.0 with VS 2005, but the same goes if I use 7.5 or 7.1, and I did everything correctly, moving the Platform SDK include to the top of the list in the include options, etc. Any help is appreciated.

Redrawing problems while using ATL Dialog and Bitmaps

Hi all,

I am using ATL Dialog for downloading and streaming video from a remote server.

The dialog box is having somany Bitmaps for buttons and other controls as well as a bitmap image as a skin.

Every thing is working fine but if i am downloading a video with more than 1 part(each part will be of 20 secs duration) then the dialog box is not redrawing properly and i have to kill it and re-login.

The downloading process works in a thread.

I am not handling WM_PAINT message.

Can any one help over this.

Hi All,
I am developing a toolbar for Outlook. I have placed an edit box on the tool bar. Now I want that when I change the text in the edit box, I should be able to handle the EN_CHANGE notification. Can somebody tell how this can be done?
Currently when I press the enter key I am able to get the value from the edit box, this is also achievable when I press tab and click with the mouse anywhere else on the screen.

Somethings seem HARD to do, until we know how to do them.

subclassing without resource

15-Jan-07 11:12

Hi,

I need to customize the CEdit control to use character masks. I thought of subclassing but the CEdit controls I need to customize are on a view that is created from scratch, so there is no CEdit resource to attach to with a GetDlgItem. The existing CEdit controls are created with a call to Create().
How can I subclass without a resource?

Thanks,
Merlinos

cs.style &= ~FWS_ADDTOTITLE ;
