__unnamed_XXXXXXX_1 why?

Hi,

I'm moving my app from the VC6 environment to the VS.net environment and while the app comiles I'm confused about the behaviour of the Class View window.

All of my typedefs now appear as enreies of the __unnamed_XXXXXXX_1 variety.

Thus:

typedef struct {<br />
  DWORD state[4];                                   /* state (ABCD) */<br />
  DWORD count[2];									/* number of bits, modulo 2^64 (lsb first) */<br />
  unsigned char buffer[64];                         /* input buffer */<br />
} MD5_CTX;

Results in :
__unnamed_2a850dbe_1

and:

typedef enum<br />
{<br />
	POOL_MASTER,<br />
	POOL_SLAVE,<br />
}POOL_THREAD_TYPE;

in: __unnamed_ddd563c5_1

Does anyone know why its doing that and how I stop it ?

Hail

Try to use full typedef notation, i.e.

typedef struct|enum type_name {<br />
...<br />
...<br />
} name;

In you case it will be something like

typedef struct _MD5_CTX {<br />
DWORD state[4]; /* state (ABCD) */<br />
DWORD count[2]; /* number of bits, modulo 2^64 (lsb first) */<br />
unsigned char buffer[64]; /* input buffer */<br />
} MD5_CTX;

Hope it'll help.

Switching listbox style => scroll bar gone

Hello colleague-CP'ers,

Situation:
I need to switch a listbox from single selection mode to multiple selection mode.
I use the code found at
http://www.codeproject.com/combobox/RecreateListBox.asp[^]
that in fact recreates the listbox.

Problem:
After recreating my listbox (that contains a lot of items) it doesn't have a scroll bar anymore. The scroll bar is GONE!

Anybody an idea?
Anybody had the same?
Other ideas to make a single selection list box a multiple selection one and vice versa?

I have developed an application using VC6.0.Its a dialog based application when I run this on XP it never resizes my dialog it remains only in two modes either maximized mode or minimized...what could be the problem...If somebody has some idea please do let me know.
Thanks in advance

So it appears as if it's remembering the previous size in the registry or somewhere. Since it's your app, you should know where (or at least be able to find out). So go there and clear those settings.

Hey Alvaro,

Can you please elaborate on the settings you are talking about that I need to clear???

The problem comes, once I minimize the window and then I click it to restore, the icon turns into a pressed/highlighted icon but window doesn't come up then I have to right click and select maximize from the menu then only I can view it.
This problem is there in XP and works fine on all other windows versions.

My feeling is that it forgets it's previous size. I am not able to figure out whether this my programming bug or Windows problem.
Both the ways I do not have any clue as what to do

It's our customers requirements and have to fix it urgently. I am stuck I would appreciate if someone can help me on this or point me to some mailing list/discussion forum etc.

Thanks
Prateeti

Check the datatypes you are using for the returned value.

Why use ODBC? Ado simplifies life so much.

You'll need to supply more details of the actual error message as the SQL string looks fine.

Have you thought about using a stored procedure and ADO command object instead.

How to get the system font

Hi,
I have developed an application where I want to display something in tree control using system font. I dont know how to get the system font and then how to display it in tree control..anyone has some idea..please do let me know.
Thanks in advance

Mmmh ...
I don't really understand what you mean by 'system font', but if you mean the current font in your control, there's several possibilities :

CWnd::GetFont will give you a handle to the font in the win. You can then use a CFont object, and assign it the font with CFont::FromHandle.

To get the font used in your tree control, add a member variable

CFont m_Font;

.
Then if you have a CTreeCtrl, put it that way in your OnInitDialog() or whatever:

m_MyTreeCtrl.SetFont(m_Font);

Or, if you do only with the IDs,

CTreeCtrl* pTree = GetDlgItem ( IDC_TREE_LABEL );
pStatic->SetFont( &m_Font );

~RaGE();

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
