You could make the application yourself, and store a small image in its resources. Also, a string saying "<none>" in the string table.

Then, your main app can either put the image straight to the device, or make a copy of mystubapp.exe, and change the image resource to be the one to upload later, and the string to be the name of the resource?

That's all very handwavy stuff, but have a look at ::UpdateResource[^] for more information on my Cunning Plan (tm)

MFC: Removing sunken border from a CFormview displayed in a CFrameWnd

Hello,

I'm creating a Wizard generated MFC application. The right pane displays a CFrameWnd, which in turn displays various views at different times. Whenever it displays a CFormView, there is an unsightly sunken border around its perimetre. This sunken border does not appear if I display a CListView, for example.

How can I remove this sunken border?

Regards,
Sternoceral

Change the style of the window in OnCreate().

What function should I call from within OnCreate()? I've found a glossary of window styles, including WS_BORDER, which creates a bordered window, but there is no such style for creating a window without a border. I would have imagined that I'd have to explicitly state I wanted a border in my CFormView derived class, but that is evidently not the case....

Thanks

I've figured it out:

BOOL CMyView::PreCreateWindow(CREATESTRUCT& cs)
{
// TODO: Modify the Window class or styles here by modifying
// the CREATESTRUCT cs

cs.style = WS_THICKFRAME;
return CFormView::PreCreateWindow(cs);
}

Thanks,

You may want to be careful in the way you do this.

This is the proper place to change window styles before a window is created...

BUT...

You've set a window style (without any other styles like WS_VISIBLE, which is fine if
that's what you want) but then you call the base class PreCreateWindow(), assuming the
base class implementation would keep your style setting.

It's safer to call the base class first to fill in the defaults for the CREATESTRUCT, then
alter the style flags as desired.

Cheers!

Why don't you outsource your development to the U.S.?

Oh yeah, you have to post your question one time.

Hi,

CString* strData;
When I am calling "delete [] strData" , I am getting a crash . What are the possible reasons for getting the crashes.

you didn't initialise strdata as new?

CString *strData = new CString();

then use

delete strData;

I have initialised. I forgot to mention.

Before deleting , I am checking whether strData exists or not as follows.

if(strData)
{
delete [] strData;
}

The if condition is satisfied , but a crash when deleting strData.

Why you need [] in delete as it is a single pointer variable ?

It is applicable when you are trying to delete an array of pointer.

CString* strData = new CString;<br />
<br />
if(NULL != strData)<br />
{<br />
 delete strData;<br />
}

How did you allocate memory to strData pointer ? Please post the code snippet.

CString* strData;
int nCount;
if(nCount > 0)
{
strData = new CString[nCount];
}

.
.
.
delete[] strData;

I have understood the problem , Paresh . The nCount is 0. So never the memory is allocated . But what should be the condition to test whether strData is actually initialised (strData is an array of pointers of CString type) before it is actually deleted.

There is such a condition only if you're disciplinate programmer:

CString* strData = NULL; // always initialize pointers
int nCount;
if(nCount > 0)
{
strData = new CString[nCount];
}
...
if (strData)
{
  delate [] strData;
  strData = NULL; // always mark deleted pointers
}

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

So, you did something like this ?
CString pArray = new CString[10];

If yes, then you need to use delete[] instead:
delete[] pArray;

Initialise strData with NULL and check strData against NULL before deleting.

CString* strData = NULL;<br />
int nCount;<br />
if(nCount > 0)<br />
{<br />
strData = new CString[nCount];<br />
}<br />
<br />
.<br />
.<br />
.<br />
if(NULL != strData)<br />
{<br />
delete[] strData;<br />
}
