Which part of developing this application do you need help with? How are you connecting to the DB?

One such way is via ODBC. Have you created a DSN? If so, just derive a class from CRecordset. You can also have a DSN-less connection.

Hi guys,
I hope my question will be peace of cake for you. Here it is:
CmyClass cl;
<br />
How to define it, so I can create it in a function Init() and destroy it in function FreeAll()?
If I declare it in a function it will be created and destroyed within it.
If I declare it as a global variable, it will create it in the declaration (wherever this take place in the program).
Well, I can use 'CmyClass *cl', but in the code I will have to use '->' instead of '.', which ... makes me angry.
Is there another approach?

Technically (AFAIK) you can't.
You may however use
- a wrapper of the class providing access to (something similar to lazy initialization or singleton patterns)
or
- use, whenever needed, a reference as alias to the dereferenced pointer to avoid pointer syntax.

Could you give me an example?
Sorry I'm new in C++ but I'm learning very fast when I see a piece of code.

for instance, suppose your class having 2 methods DoSomething, JustDoAnotherThing:
CmyClass & myObj = *_pcl;
myObj.DoSomething();
myObj.JustDoAnotherThing()
...

wait, friend, wait: you're going to discover some interesting issues using references.

oh, I think I already did ... 
I tried (global variables):
CakRadioBox *prb = NULL;
CakRadioBox & rb;
well ... it doesn't work, it require initialization
I changed it to:
CakRadioBox *prb = NULL;
CakRadioBox & rb = *prb;
so far so good, but when in Init() I wrire:
prb = new CakRadioBox(10, 134, 44, 24);
rb = *prb
I receive exception

Have your static box the SS_BITMAP style set?

Just use the no_namespace keywork in the #import "..."
Then you must refer each function with the namespace before:
#import <c:\app\office\office\excel9.olb> no_namespace
...
Excel::_ApplicationPtr excp;

The most popular "free" mail providers over the Internet are yahoo, hotmail, google and newly "live". But unfortunately I can't send them my email messages using smtp, because I don't know the address of their smtp servers. Can any one introduce me some of them that work with smtp clients like "telnet" or something (I mean those which don't need "webmail" pages over the Internet to send eMail to them)?
Thank you masters!

I am using a CTreeCtrl control in my application.
It has a root with all other item as its child. Now what I want is that Whenver a child item is clicked its value should be printed in a edit box.
For this I am using
ON_NOTIFY(NM_CLICK, IDC_TREE_KEN_PUSH,OnSelchangedTreectrl)
event handler and the code is as follows:
void CChatDlg::OnSelchangedTreectrl(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
HTREEITEM hItem = m_ctrlKenPush.GetSelectedItem();
CString strItemText = m_ctrlKenPush.GetItemText(hItem);
if(strItemText!=_T("General"))
SetDlgItemText(IDC_EDIT,strItemText);
*pResult = 0;
}
But the problem is that when i click a child node its parent values gets printed .
Please tell whats the problem.
