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;

How can I send an eMail (using smtp) to yahoo "free mail services"?

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!

CTreeCtrl Problem

Dhiraj kumar Saini19-Oct-08 23:09

19-Oct-08 23:09

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;
         // TODO: Add your control notification handler code here
		 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.

Zero copy on windows

Hi All,
Is there any facility/API available on windows which will give me file copying functionality where number of copy operations involved are minimal?

Usually kernel mode APIs and DMA stuff creates few number of redudent buffer copy operations. Can we avoid it?

On unix they have such functionality

I'm almost sure that there isn't any thing like that in Windows API.

The standard functions: CopyFile, CopyFileEx, MoveFile don't work as you want:

PD: If you find such functionallity please post it. Laugh | :laugh:

Hi again, I remembered a way to copy files across network:

TransmitFile Function

The TransmitFile function transmits file data over a connected socket handle. This function uses the operating system's cache manager to retrieve the file data, and provides high-performance file data transfer over sockets.

Note This function is a Microsoft-specific extension to the Windows Sockets specification.

Hope this one works...

Are you sure you want to draw directly on the dialog ? In general, it doesn't make a lot of sense. A better approach would be to create a custom control and delegate the work to it.
What are you trying to achieve exactly ?

Ok but this doesn't answer my question. Do you really need to draw on the dialog itself rather than using a custom control ? Here[^] is an article about creating custom controls. It is much cleaner than drawing directly on the dialog.
