how catch combination of key??

[Mohammad Omer]

Hi,

I am working on SDI base application using vs2k5. I need to perform
some task on combination of keys (link ctrl+v). I wrote WM_KEYDOWN
message in my view for control command keys (like Delete, Insert, etc)
but unable to catch combination of keys in WM_KEYDOWN message. I tried
to use GetKeyStatus function in WM_KEYDOWN message but not gets any
positive results. Please guide me, how I can control combination of
keys in WM_KEYDOWN message, like, if I wants to perform some task on
ctrl+v for this, what I do for it??

Regards,

For the situation you mentioned you'd normally create an accelerator
entry for the key combination in the application's resource.

And be sure to call TranslateMessag e from your message loop.

entry for the key combination in the application's resource.

It will not work for me because I need to perform some actions on ctrl
+v. I tried following code in WM_KEYDOWN which work on ctrl+shift+v
but not working on ctrl+v.

if(nChar == 'V' && (0x8000 & GetKeyState(VK_ CONTROL)))
{
//do some thing
...
}

can you please guide me how i can fix this problem??

What do you mean? That's what accelerators are intended for.

>I tried following code in WM_KEYDOWN which work on ctrl+shift+v
but not working on ctrl+v.

if(nChar == 'V' && (0x8000 & GetKeyState(VK_ CONTROL)))
{
//do some thing
...
}

I can't see any apparent reason why that shouldn't work - what code do
you have for the Ctrl+Shift+V case?

Hi Dave!

This code works when I removed all combination related to Ctrl and
Shift keys from Accelerated. The following entries was in my
accelerated file.
Shift+Insert
Ctrl+C
Ctrl+X
But I am not able to understand why it was not working. I was trying
to control Ctrl+V key combination which was not in my accelerated keys
list. Accelerated key has high priority and then pass to messages??

Hi Dave!

Shift keys from Accelerated.

Can you explain in more detail what you removed?

>The following entries was in my

Shift+Insert
Ctrl+C
Ctrl+X

By "accelerate d file", do you mean the accelerator table resource for
your application - or something else?

>But I am not able to understand why it was not working. I was trying
to control Ctrl+V key combination which was not in my accelerated keys
list.

Which (and what type of) window are you trying to catch these
accelerator key combinations for?

Dave,

Can you explain in more detail what you removed?

I was making SDI base application and by that time following
information I seen, which includes Ctrl+V as well.

IDR_MAINFRAME ACCELERATORS
BEGIN
"N", ID_FILE_NEW, VIRTKEY,CONTROL
"O", ID_FILE_OPEN, VIRTKEY,CONTROL
"S", ID_FILE_SAVE, VIRTKEY,CONTROL
"P", ID_FILE_PRINT, VIRTKEY,CONTROL
"Z", ID_EDIT_UNDO, VIRTKEY,CONTROL
"X", ID_EDIT_CUT, VIRTKEY,CONTROL
"C", ID_EDIT_COPY, VIRTKEY,CONTROL
"V", ID_EDIT_PASTE, VIRTKEY,CONTROL
VK_BACK, ID_EDIT_UNDO, VIRTKEY,ALT
VK_DELETE, ID_EDIT_CUT, VIRTKEY,SHIFT
VK_INSERT, ID_EDIT_COPY, VIRTKEY,CONTROL
VK_INSERT, ID_EDIT_PASTE, VIRTKEY,SHIFT
VK_F6, ID_NEXT_PANE, VIRTKEY
VK_F6, ID_PREV_PANE, VIRTKEY,SHIFT
END

After that I was removed ID_EDIT_PASTE resource ID from accelerator
table and try to capture Ctrl+V by code but it was not working.. One
by One I removed all entries from accelerator but WM_KEYDOWN message
start working on when no entry left in accelerator table..

By "accelerate d file", do you mean the accelerator table resource for
your application - or something else?

I wrote "accelerato r file" by mistaken that is accelerator table..

OK, I just wanted to be clear that it was the resource accelerator
table you were referring to.

I don't immediately know why that should be - are you saying that you
don't receive *any* WM_KEYDOWN messages, or just the ones that had
accelerators defined?

Why do you want to do the key detection in code rather than relying on
the existing accelerator & command messages they will create?
