Hey, Sorry for late. just i came.
This is also one way.

CDialog dlg;//This can be any window
dlg.ModifyStyle(WS_MAXIMIZEBOX,0);//To remove the max btn.
dlg.ModifyStyle(0,WS_MAXIMIZEBOX);//To add the max btn

//Like this you can add any style and remove any style

This is simple way. At runtime you can change the style of any control or any window. see about modifystyle in msdn.

Nice talking to you. Blush | :O

Your CFont object will be destroyed when it goes out of scope.
Have a CFont member variable instead.

Create the font you like in your constructor:

LOGFONT lf;
memset( &lf, 0, sizeof( LOGFONT ) );
lf.lfHeight = -20;
lf.lfWeight = FW_BOLD;
m_LargeFont.CreateFontIndirect( &lf ); // m_LargeFont is a CFont member

...and when you like to use it:

m_bFreq.SetFont( &m_LargeFont );

It's supposed to be hard, otherwise anybody could do it!

If u r trying by SDK then u need some books to refer fist .
If u use a MFC ,then
Use a class wizard to create a new project in MFC (SDI)
Then create a dialog box from resource editor ,create
a class for ur dialog box say CDlg_myname .
Create a Object of the dialogbox class and use this code in
ur CMainFrm OnShow() event .
CDlg_myname dlg1;
Dlg1.DoModel();

on the resource editor, you can drag a button from the toolbox to your dialog resource, give it an explicit ID and then double click on it to access its OnClick event handler...
there, add the code that is to be executed when the button is clicked on...

Hi,

I've done some searching to implement a windows explorer kind of interface. Will VisualStudios.Net will start you off with the splitter control, it's not exactly what I wanted. I would really like to integreate the shell features of windows explorer into my application. I've searched for hours on how to do this without having to completely reinvent the wheel, but either nobody seems to know or nobody wants to give out the information.

I've seen libs that you can pay for that do the job for you (http://www.ssware.com/articles/creating-explorer-clone-in-visualc++-mfc.htm) , but I don't see the point in paying for a library when I can write it myself.

I've searched these forums for this topic, but havent' found any info (maybe i just suck).

So is there a way to get a windows style explorer control into your application without writing it from scratch. I wish I could rip out the list view from the open file dialog and the tree view from the folder browser dialog. Either C++ or C# solutions/ideas would be welcome.

delete m_pdbf in destruction?

hi, all

when this app open the customer dbf file, it creats index as well, it didn't really has m_pdbf = new...., but it seems like need to be deleted in dbCustomer::~dbCustomer(), here is the steps:

BOOL dbCustomer::Open( const char *pszFileName, bool bReindex )
{
ASSERT( m_pdbf == NULL );
int nError = 0;
std::string strErrMsg = "";

if ( !OpenDbfNtx( &m_pdbf, pszFileName, NULL, NULL, nError, &strErrMsg ) )
throw DbfAccessException (string(pszFileName) + " not found", RC_DBF_UNABLE_TO_OPEN);

SetIndex( pszFileName, m_pdbf, bReindex );

m_pdbf->set_order( "CUSNUM02" );

return BindFieldOrdinals();
}
CB_DBF_NTX* const p = OpenDbfNtxHelper( szDbfName, szIndexName, szIndexKey );
CB_DBF_NTX* pDbf = new CB_DBF_NTX( const_cast<char*>( szDbfName ) );

the wrapper seems conplicated, it's getting infor from library files.........thanks for your time

depends on your design.

if there's an Open method, maybe there's a Close method also that will close the database and delete the object.

if you're not certain about that, put the delete in the destructor.

Order of operation precedence:

hours << day << endl;

is equal to

hours << (day << endl);

You want:

hours << day;
hours << endl;

Re: Writing Data to Files

The associativity of << is 'left to right'. So:

hours << day << endl;

is equal to

(hours << day) << endl;

Only the associativity of unary and assignment operators is 'right to left'.

You can see it here.
