Hello,

how can I cancel(close) the popup menu when I decide to do that in the WM_INITMENUPOPUP notification handler ?
I've tried to call DestroyMenu() on provided menu handle but it does not work althought it returns 1 (success).

Thank you!

How you are creating menu, can you show it?
Because,I suspect, you are using temporary handle to menu(which is supposed not to use), to destroy menu.

User is creating the menu so I think that handle is temporary. I haven't found this information that it's not for destruction - so how can I close the menu ?
I've also tried PostMessage(WM_CHAR,VK_ESCAPE,1); to owning window's handle it also failed.

I've got it. It seems that sending WM_CANCELMODE does the trick Smile | :)

Hi,

only a (untested) proposal.

Have you tried WM_MENUSELECT?
This message is (possible) send before WM_INITMENUPOPUP.

-> catch the selection before the popupmenu is created

It can be used for destruction, but its temporary, means you cannot store it ,and use from some other function.

Can you show some code?

User press context menu key or right click. I'm not storing handle for later use.

But it does not matter now as I've wrote before i've solved it by sending WM_CANCELMODE message.

Thank you all guys for your time!!!

hi,

check for CFont in MSDN.

//

CFont fntArial, fntBoldSwiss;
fntArial.CreateFont( 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, "Arial" );
fntBoldSwiss.CreateFont( rcClient.Height()/20, 0, 0, 0,
FW_BOLD, TRUE, FALSE, 0, ANSI_CHARSET,
OUT_TT_PRECIS, CLIP_DEFAULT_PRECIS,
DEFAULT_QUALITY, DEFAULT_PITCH | FF_SWISS,
NULL );

Your question doesn't really make sense. If you pass a char array to a dll that is in charge of the display of the string and if you cannot change it, then it is impossible. A char array doesn't contain any formating informations, it contains data only (so, only the letters of your string).

You can set fdwUnderline to true in CreateFont and if you use of CDC for write to screen use SelectObject

The default project charset setting in VS2005 is using UNICODE, so the MessageBox maps to MessageBoxW, which takes unicode strings as its input.
You can 1. changing your project's setting from using UNICODE to MBCS 2. enclose each of the string appeared in your source files with _T(). Or you can do both.
The _T macro will map the string to wide char string constant if the project is set to use UNICODE, and will map the string to normal ANSI string constants if the project is set to use MBCS charset.

TEXT() is working; also for _T macro #include <tchar.h> is solve the problem.

What does this mean? _T() macro is defined in tchar.h; But again finally expands to L""

If an application is using several sockets then the select() function may be used to find out which ones are active.

See here. You will get a lot of information relating to blocking and non-blocking sockets.

Somethings seem HARD to do, until we know how to do them.
