Hello,

Your code above was useful.I wanted to find out how many rows should be read from the sheet.For that I have used the following but it doesn't work.

LPDISPATCH lpDisp;
lpDisp = sheet.GetUsedRange();
range.AttachDispatch(lpDisp);
range.Select();
range.GetRows();
long lTotalRows = range.GetCount();

Any ideas

Thanks
Prithaa

Hello Prithaa,

I am not sure, but I think the following should work (did not test it though)

Range Rng;
Range Rws;

Rng = Sheet.GetUsedRange ();
Rws = Rng.GetRows ();
long lTotalRows = Rws.GetCount ();
Rws.ReleaseDispatch ();
Rng.ReleaseDispatch ();

There is no need to use a separate LPDISPATCH and then connect it to a Range variable; you can do this directly as above.

William

Printf %d and %ld

Hello everyone,

I think printf %d works fine with signed, unsigned and negative integer values, and the same as %ld for long. Is that correct? If not, do we need to special conversion?

thanks in advance,
George

Hi George,

Yep, you are right. Although I must say that in today's implementation there is no difference between int and long (they both are 4 bytes)

I tried with

long int li = 0xFFFFFFFFL;
unsigned long int uli = 0xFFFFFFFFL;
printf( "%ld %ld\n", li, uli );

short int si = 0xFFFF;
unsigned short int usi = 0xFFFF;
printf( "%d %d\n", si, usi );

And the result was
-1 -1
-1 65535

- NS -

Hi All,

I have an application which updates itself when new version is available . But thises updates are having a problem if the app is run by a user having non admin rights , as the service alters the files in %program Files% folder , registry settings while updating . if the user is a non admin then these processes fail and thus the update fails . Is there any way by which i can find if the logged in user is a administrator or not ? so that i dont allow updates for a non admin user ???

Smile | :)

Thanks in Advance

it is declared in ShlObj.h and is located in the dll shell32.dll. You need to install platfor sdk to class this function. Optionally you can dynamically load the dll and call it with the help of LoadLibrary and GetProcAddress().

Depends on the version of Visual Studio - the function was added for W2k. It is included in the VS2005 headers.

Hi! I m trying to view a MS Word *.Doc File in HTML view in VC++,by using Navigate2() function of CHtml view class. But the problem is that when the File viewed on HTML view all controls work,means i can right click on it,save this file by using F12 key ,open its help by pressing F1 key and all the other control.

Why wizards generate enum IDD for dialogs?

NiceNaiduCan somebody tell me the reason ,Why wizards generate enum IDD for dialogs?

The IDD enum of a dialog class contains the ID of dialog in the resource.

enum { IDD = IDD_MYDLG_DIALOG };

This IDD is passed in the constructor of your dialog to CDialog constructor.

CMyDlg::CMyDlg(CWnd* pParent /*=NULL*/)<br />
	: CDialog(CMyDlg::IDD, pParent)<br />
{<br />
}

You can simply get the ID of the dialog with a statement like CMyDlg::IDD

So when creating a dialog, we can use like

CMydlg dlg;<br />
dlg.Create( CMydlg::IDD, 0 )

Instead of

CMydlg dlg;<br />
Dlg.Create( IDD_MYDLG_DIALOG, 0 )

When MFC was initially developed a statement like the below one was not supported.

Class CMyDlg: public CDialog<br />
{<br />
  ....<br />
<br />
  public:<br />
  static const DWORD IDD = IDD_MYDLG_DIALOG;<br />
}

Also the trick of keeping an enum doesnt increase the memory size of object Smile | :)

CHTMLView and Compound File (IStorage)

Hi,

My problem is that I dont want to have my HTML files unprotected as simple files that everyone can view them.

So, Is there anyway to use with CHTMLView, HTML files that are stored in Compound File (IStorage) directly (without extracting them in a temp file)? Alternately is there any other method to use CHTMLView with HTMLs files that are protected in some way ?

I checked up the standard Windows Help *.CHM format but i think its too much complicated to use a such kind of solution.

Any ideas ?
