I tried to get the currently clicked item on the tree ctrl using the foll.
code But it does not return me the current item.
What could be wrong
void COSDDlgBar::OnNMClickTree1(NMHDR *pNMHDR, LRESULT *pResult)
{
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
CTreeCtrl *pm_Tree = NULL;
pm_Tree = (CTreeCtrl*)GetDlgItem(IDC_TREE1);
HTREEITEM hItem = pm_Tree->GetSelectedItem();
*pResult = 0;
}

I don't think the selection will change until after the NM_CLICK has been processed.
Try handling TVN_SELCHANGED and call your code from there. (or better yet, use the itemNew variable in the NM_TREEVIEW struct)
 Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

Try it like this:
void COSDDlgBar::OnNMClickTree1(NMHDR *pNMHDR, LRESULT *pResult)
{
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
CTreeCtrl *pm_Tree = (CTreeCtrl*)GetDlgItem(IDC_TREE1);
POINT pt;
GetCursorPos(&pt);
pm_Tree->ScreenToClient(&pt);
HTREEITEM hItem = pm_Tree->HitTest(CPoint(pt));
*pResult = 0;
}
_outp(0x64, 0xAD);
and
__asm mov al, 0xAD __asm out 0x64, al
do the same... but what do they do??

i want to send mail from my program without having email account, and without automation.
is it possible?

Sure it is possible.
There are two ways of sendinig an EMail:
1. use a relay server
if you chose this option you you need a SMTP server that does not need authentication. You can use the SMTP-Server that is part of Microsoft's IIS.
2. Send directly to the recipient
Just do a MX DNS lookup on the email adress and then send post the mail directly to the recipients mailserver using SMTP over port 25.
Then you need to create a mime message for the mail you'd like to send. (see rfc 822 for this).
Then you need to deliver the mail. Again two options:
1. if you use the IIS's SMTP server (or any other server that supports a drop directory) you can simply save you message to the mailserver's drop directory (C:\Inetpub\smptroot\pickup). The SMTP server will queue the mail and send it to the recipient.
2. open a connection on port 25 to the recpients mail server, send HELO etc...
An answer for the implementation details of MIME mails and the SMTP protocol would exceed the frame of the forum by far.
But as far as i remember there are good articles on both issues.

Hi,
For some reason, if I call multiple sendto's, like this:
sendto(sock, etc etc);
sendto(sock, etc etc);
sendto(sock, etc etc);
Then I have a recvfrom loop threaded on my client side, the recvfrom will often receive all the data from multiple sendto's in one 'big' packet and stuff it all together so I can't parse it correctly. What the hell?? Isn't it possible to send a number of TCP packets right after each other and have them received separately??
Thanks!

No, because TCP is a streaming protocol.
Because TCP is reliable (in-order and reliable), you can however wait until you have read a certain number of bytes and then assume that is one 'packet'.
For fixed size packets this means you end up with something like
read( packet, sizeof(Packet) )
read( packet, sizeof(Packet) )
And for variable size packets:
read( packetsize, sizeof(long) )
read( packet, packetsize)
read( packetsize, sizeof(long) )
read( packet, packetsize)
As an aside, ::send() and ::sendto() are generally used for UDP, whilst TCP normally only uses ::send()
|

|

Ah, I see.
I think I'll add an 'end character' to the end of my sent packets and parse them on the client end by iterating through char by char and each time I hit an 'end character' I'll treat the part before that as a 'packet'.
Thanks!!

I want to disable the SAVE toolbutton on the toolbar.
For this I tried the foll in the MainFrame's OnCreate Event.
TBBUTTONINFO buttonInfo;
buttonInfo.cbSize = sizeof( TBBUTTONINFO );
buttonInfo.dwMask = TBIF_COMMAND || TBIF_STATE ;
buttonInfo.idCommand = ID2_FILE_SAVE;
buttonInfo.fsState = TBSTATE_INDETERMINATE ;
int xxx = m_wndToolBar.GetToolBarCtrl().SetButtonInfo(ID2_FILE_SAVE, &buttonInfo);
I wonder I initially got the SAVE toolbutton to grey out .But it wont happen anymore I dont understand why .Now its hidden but clicking it brings the Save Dialog box which means its still not disabled.
In another function I tried to enable it with the foll.code.
TBBUTTONINFO buttonInfo;
buttonInfo.cbSize = sizeof( TBBUTTONINFO );
buttonInfo.dwMask = TBIF_COMMAND || TBIF_STATE ;
buttonInfo.idCommand = ID2_FILE_SAVE;
buttonInfo.fsState = TBSTATE_ENABLED ;
int xxx = m_wndToolBar.GetToolBarCtrl().SetButtonInfo(ID2_FILE_SAVE, &buttonInfo);
But it wont enable .It wont become visible either.I dont understand.Please let me know the mistake.
Thank u .

thanx for ur help .but the documentation tells to update through update handler. I havent clearly understood how the handler can be associated to a toolbutton.

I don't feel like repeating here what the article says, so read the article I linked to and be sure to follow the links in the article, they link to more detail.
Basicly you link the command handler, the command update handle, the command's menu item, the command's toolbar button, the command's toolbar bar button's tooltip text, and the command's status bar text through a common ID number.
