Re: Socket Program Problem!!!

Maybe you should empty the socket buffer before restarting to use sendto again. How are you authenticating it (from the sender point of vue) ? Does the sender got something from the reciever (confirmation message ?) so that he is allowed to send data ? If yes, this could have been sent back if the buffer was not emptied. I experienced that a couple of months ago.

I was just looking for it, but i did not find anything, and i cannot remember myself Frown | :(

Sorry .. I stiil think this should not happen if you receive the same amount of byte that you send, so be careful to the length parameter in sendto. Sorry i cannot help more.

HMENU hMenu is not the resource ID of your menu resource, but the menu handle you get from the CMenu::hmenu member or from the ::LoadMenu() call which created your menu.

OK. I try to explain:
Any function in global space can (should) be preceeded with the scope operator :: This means it is not from the loacal namespace (e.g. class) but global. Most of the time, the compiler can figure it out itself, but it helps human readers to explicitly say that you are calling the global scope function, and not some member.
::LoadMenu() is a WIN32 function in global scope. MSDN will be of help with the details.
CMenu::m_hmenu is the member variable m_hmenu from the namespace CMenu. CMenu is the MFC class dealing with menus. Also MSDN helps here.

Hope this helps

i don´t think i understand it, but i tried this:

EnableMenuItem(::LoadMenu(IDR_MENU1), ID_EXTRAS_SERVICE, MF_GRAYED);

but it do not work? do you mean something different? can you give me an example?

thanks

You probably did the loading of the menu from resources somewhere before.
You said you are using MFC, so you will have a variable of type CMenu somewhere, which represents your IDR_MENU1, right?
Like this:

...
CMenu menuOne;
menuOne.LoadMenu(IDR_MENU1);
...

Then you would write:

BOOL e = ::EnableMenuItem( menuOne.m_hmenu, ID_EXTRAS_SERVICE, MF_GRAYED);

And then you can see in the MSDN-entry for EnableMenuItem, that the 3rd parameter in your code is not correct:

MSDN: "This parameter must be a combination of either MF_BYCOMMAND or MF_BYPOSITION and MF_ENABLED, MF_DISABLED, or MF_GRAYED"

So, you have to add either MF_BYCOMMAND or MF_BYPOSITION to it.

And adding a line

BOOL e = ::EnableMenuItem(menu, /*item and flag parameter here*/)

at the bottom does not work?
Does it compile?
Your HMENU is valid?
You corrected the flags like MSDN shows?

I don't know if this is what you want, it is a cut/paste from one of my progs but try:-

CWnd* pMain = AfxGetMainWnd();

// Get the main window's menu
CMenu* pMenu = pMain->GetMenu();
CMenu* pSubMenu = NULL;

// Now get a handle to the pop up menu, the 1st one e.g. File
pSubMenu = pMenu->GetSubMenu(0);
pSubMenu->EnableMenuItem(ID_FILE_TRANSFER, MF_GRAYED);

I have a parent dialog and some child dialogs in it. The parent dialog have bitmap background. So I want its child dialogs to be transparent? How can I do that? (Same as PropertySheet with Wizard Mode and PSH_WATERMAKE flags)

(I have only return TRUE on OnEraseBkgnd(), the child dialogs has been transparent, but static controls on child dialog are still not transparent... Cry | :((

)

Thanks for any help!

Thanks for your help. But the background of these static controls (on child dialg) is different from the background of the parent dialog because I has used a bitmap background, not a solid background.
