VC single-document shortcut Programming

Let's take a look at the keyboard virtual code before talking about shortcut key programming,

There are two types of keyboard messages:
Non-system key wm_keydown wm_keyup
System key wm_syskeydown wm_syskeyup

Virtual Value

Vk_lbutton 01 left mouse button

Vk_rbutton 02 right-click

Vk_cancel 03 control-Break Process

Vk_mbutton 04

Vk_back 08 backspace key

Vk_tab 09 Tab key

Vk_clear 0C clear key

Vk_return 0d enter

Vk_shift 10 shift key

Vk_control 11 CTRL

Vk_menu 12 Alt key

Vk_pause 13 pause key

Vk_capital 14 Caps Lock key

Vk_escape 1B ESC key

Vk_space 20 spacebar

Vk_prior 21 page up key

Vk_next 22 page down key

Vk_end 23 end key

Vk_home 24 Home Key

Vk_left 25 left arrow

Vk_up 26 up arrow key

Vk_right 27 right arrow key

Vk_down 28 down arrow key

Vk_select 29 select key

Vk_execute 2B execute key

Vk_snapshot 2C print screen key

Vk_insert 2D ins key

Vk_delete 2E DEL key

For numeric and numeric keys on non-keypad, simply add the key to single quotes.

For example, key A: 'A'

1 key: '1'

Add the virtual function pretranslatemessage to the cxxxapp class in a single-document application.

Bool chbplayerapp: pretranslatemessage (MSG * PMSG)
{
// Todo: add your specialized code here and/or call the base class
If (PMSG-> message = wm_keydown)
{
Switch (PMSG-> wparam)
{

// Shield the ESC message
Case vk_escape:
Return true;
Break;

// Block the Enter key message
Case vk_return:
Return true;
Break;

// Ctrl + c
Case 'C ':
If (: getkeystate (vk_control) <0)
{
}
Break;

// Ctrl + Shift + S
Case's ':
If (: getkeystate (vk_control) <0) & (: getkeystate (vk_shift) <0 ))
{
}
Return cwinapp: pretranslatemessage (PMSG );
}

Add a keyboard response event in the dialog box

1. Add Windows message handle in classview add WM-KEYDOWN and WM-KEYUP, add your Ural functions add pretranslatemessage

2. Add bool ** DLG: pretranslatemessage (MSG * PMSG)

{

If (PMSG-> message = wm_keydown)

{

If (PMSG-> wparam = vk_return) // directly use a virtual code instead of the corresponding key.

Setinfo (wdk_ OK); // enter the corresponding OK

}

If (PMSG-> message = wm_keydown)

{

If (PMSG-> wparam = vk_back) // you can directly use a virtual code instead of the corresponding key.

Setinfo (wdk_c); // Delete the backspace

}

Return cdialog: pretranslatemessage (PMSG );

}

3. usage of the key combination: (In this example, the CTRL + x key is returned)

Bool cmydilog: pretranslatemessage (MSG * PMSG)

{

If (PMSG-> message = wm_keydown)

{

Switch (PMSG-> wparam)

{

Case vk_escape:

Setfocus ();

Return true;

Case 'X ':

If (: getkeystate (vk_control) <0

MessageBox ("hello ");

Return true;

}

}

Return cdialog: pretranslatemessage (PMSG );

}

F10 and ALT arent picked up by wm_keydown, you need wm_syskeydown.
You need to add: Case wm_syskeydown:
If (PMSG-> wparam = vk_f10)
Trace ("F10/N ");
Break;
