First make sure that
IDC_Pin2 to IDC_Pin9 follow each other up like 1, 2, 3, 4, etc
then change the macro to ther following
ON_COMMAND_RANGE(IDC_Pin2, IDC_Pin9, ChangePin());
That should do it

that's it, but i wanted the OP to search a bit by himself, because 1) we do not do homework here, and 2) the MSDN link I gave him provide all these informations

Hi, I'm using the TrackPopupMenu() MFC function and would like (i really have to do this for my customer  ) this contextual menu to open up on a default subitem.
I mean, assuming i have in my menu an item 1 and an item 2, and item 2 is a popup having an subitem1 and a subitem2, i need the whole menu to directly open on subitem2 selected for example.
Any idea on how to solve this ?
thanks !

Do you want to show contextmenu on the item for example in the listctrl ?
|
|
|
|
|
no i just want the contextmenu to openup on the desired subitem : a menu is a set of item and subitems, items having subitems beeing called popup because when passing on them, a sub-popup menu opens up. What i need is when i display my menu with TrackPopupMenu(), directly having a perticular sub-popmenu opened

a function HiliteMenuItem() exists and its behaviour is exactly what i'm looking for BUT it only wroks for menus with a menubar, not for popup menus (contextual ones)
someone has an idea ?

What about SetMenuItemInfo to set the state?

do you mean setting the state to MFS_HILITE ?
i think it won't work as HiliteMenuItem() function must do the same.... and doesn't work for popup menus...
but i'll try

Hi All,
Can anyone please suggest me some ideas about how to control LED's using VC++?
Thanks in advance.

 Which LED ?
|
|
|
|
|
I am trying to design a software to communicate with a LED using serial port to On/Off the LED. so any help regarding this will highly be appreciated.
Regards,
Ram
|

You can't communicate with a LED using the serial port (a LED doesn't 'communicate'). You probably meant that you communicate with some kind of harware (like a microcontroler) that will switch your LED on or off.
Well, then just send some specific packet on the link that your microcontroller can recognize.
Where are you stuck exactly ? Because it is really vague...

Oooopzzzz. I just started to do some research regarding this to gather some knowledge about controlling LEDs using software. I understood by your answer that i should need some extra hardware(Microcontroller) to control LED.
Then I must go and find something about microcontroller and controlling LED first. Anyway thanx a lot for your information. Atleast i got some idea abt this.
Do you have any idea about this without microcontroller. ( that means jus with common electronic items such as breadboards, resistors, capacitors and transistors.)
Regards,
Ram

Maybe what you could do is use one of the control line of the serial port (like CTS, but you need to check which one you could use) and then connect your LED with a resistor between this line and the ground.
But, I don't think this is the most appropriate forum to discuss about that because it is not in fact a programming question...

|
|
K thank you very much for your valuable information. I think your information is more than enough for me. I think i mus go with the microcontroller.
Thanks again.
Regards,
Ram

If you can use the parallel printer port instead, see my response.

I believe that you can do it using the parallel port using 24 volts that you should make available from your code in one of the port pins.
We have here working something like that but in that case we make an alarm to sound and we have used a relay and some cables, but only the parallel port. If we are capable to make an alarm to sound, I'm sure that you'll be able to enlight a led.
Hope this helps.

You can connect LED's to some of the pins of the parallell printer port. You will need to use serial resistors, though. Else, chances are that you will break either the printer driver circuitry (in the computer), or the LEDs themself.
You can use inpout32 (search for it) to control the individual pins of the parallell port.
