This is the code.

void CPerspectiveDoc::OnFileSave()
{

if(CurrentPath == "Untitled.vps")
{
char acFilters[] = "VPS files (*.vps)|*.vps||";
CFileDialog filedialog(FALSE, "vps", CurrentPath, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
acFilters);

if(filedialog.DoModal() == IDOK)
{
CurrentPath = filedialog.GetPathName();
JustPath = CurrentPath.Left(CurrentPath.ReverseFind('\\')+1);
}

}

What a waste of time! You haven't added the new extension to the filter! Indeed, this code will be "not working".

Sorry.I undo the extension. Here is the new code. This also not working.
void CPerspectiveDoc::OnFileSaveAs()
{

char acFilters[] = "NIF files (*.nif)|*.nif|VPS files (*.vps)|*.vps||";
CFileDialog filedialog(FALSE, "vps", CurrentPath, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
acFilters);

if(filedialog.DoModal() == IDOK)
{
CurrentPath = filedialog.GetPathName();
JustPath = CurrentPath.Left(CurrentPath.ReverseFind('\\')+1);
}

CDocument::OnSaveDocument((LPCTSTR)CurrentPath);
SetTitle(CurrentPath);

}

What is CurrentPath ? This works for me:

char acFilters[] = "NIF files (*.nif)|*.nif|VPS files (*.vps)|*.vps||";
CFileDialog filedialog(FALSE, "vps", "hello", OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,acFilters);
filedialog.DoModal();

There lies the problem, you should have declared yourself as "real".

_variant_t is defined is comutil.h
and
You should import <msado.dll></msado.dll> before using FieldPtr

unique pointer issue

13-Feb-08 17:59

Hello everyone,

Could anyone help to explain what does the two rules for unique pointer mean?

http://msdn2.microsoft.com/en-us/library/aa367294(VS.85).aspx

1.

Especially confused about "before the call"

Can use existing memory on the client without allocating new memory. When a unique pointer changes during a call from one non-NULL value to another, the pointer is assumed to point to a data object of the same type. Data returned from the server is written into existing storage specified by the value of the unique pointer before the call.

2.

Can orphan memory on the client. Memory referenced by a non-NULL unique pointer may never be freed if the unique pointer changes to NULL during a call and the client does not have another means of dereferencing the storage.

thanks in advance,
George

Try this: set the listctrl's item height to the picture's height. And there may be some tricks to set the listctrl's item height. Google it.

Print Preview and "x"-Button

Hey,

how can I prevent closing my whole SDI-App when the "X"-button in PrintPreview is pressed. All works fine, when i push the close-botton (preview closes, and CView is shown) but not by presseing the "X"?

Obviously - don't click the "X" button Smile | :)

Seriously, though, that "shouldn't" happen unless MFC thinks the window being closed is the
application's "main window", as specified by the CWinThread::m_pMainWnd member...
