880231 - overriding keyboard behaviour

Have you consulted with your classmate who's already asked a very similar question in this forum[^]?

He at least gave himself a little more time than you and asked a slightly more targeted question.

hi as we know, in a dialog box Tab and Shift+Tab change focus between ctrls, Tab to the next one and Shift+Tab to the previous one. when handling the keyboard event generated, we see that both generates the same event with the same wParam (0x09) and lParam (0x000d0001).
so how a dialog figures out which one is hit? apparently by using the function GetKeyState at the moment of handling the message. alright?
now, in a system with no tab key i want to use Up and Down keys in the place of them. at this moment the problem gets produced.
in the PreTranslateMessage of my application, i just change wParam from VK_DOWN into VK_TAB. the PreTranslateMessage of the base class (CWinApp) thinks Tab is hit instead of Down arrow. this is the behavior i intend and it's ok. but what can i do when the user hits Up arrow and expect the previous ctrl gets focused?
do i need to use SetKeyboardState and this is the only way to simulate hitting Shift key?
what can i do?
thx

Maybe this[^] article will help, with a couple of possible alternatives.

The other way to do it would be to replicate Windows tab-handling for VK_UP and VK_DOWN in the PreTranslateMessage method...

BOOL CtestmfcDlg::PreTranslateMessage(MSG* pMsg)
{
   if (pMsg->message == WM_KEYDOWN)
   {
      if (pMsg->wParam == VK_UP)
      {
         CWnd* prev = GetFocus()->GetNextWindow(GW_HWNDPREV);
         if (!prev) prev = GetFocus()->GetNextWindow(GW_HWNDLAST);
         if (prev) prev->SetFocus();
         return TRUE;
      }
      else if (pMsg->wParam == VK_DOWN)
      {
         CWnd* next = GetFocus()->GetNextWindow(GW_HWNDNEXT);
         if (!next) next = GetFocus()->GetNextWindow(GW_HWNDFIRST);
         if (next) next->SetFocus();
         return TRUE;
      }
   }

   return CDialog::PreTranslateMessage(pMsg);
}

this is a good method. indeed doing what the dialog itself does in handling these keys again in our code for another keys. but when there're many dialogs in the program and i'm not going to derive them from a common base and put this code in its PreTranslateMessage method makes it a bit not a straightforward method. the code i've to write is what the others also r working on. all keyboard handlings must occur in the application's PreTranslateMessage. i know that it's not a logical limitation, but this is what i can do.

ilostmyid224-May-09 1:23

24-May-09 1:23

please notice the following code i put in the application's PreTranslateMessage:

...<br />
case VK_DOWN:<br />
	pMsg->wParam=VK_TAB;<br />
	BYTE byKeybState[256];<br />
	GetKeyboardState(byKeybState);         <br />
	byKeybState[VK_SHIFT] = !(BOOL)GetKeyState(VK_SHIFT);  // or TRUE<br />
	SetKeyboardState(byKeybState);<br />
	break;<br />
...<br />

it must work. right?
but in CE it seems that GetKeyboardState and SetKeyboardState functions r not available. what can i do?

I'd use GetAsncKeyState[^] (which is in CE) and the SendInput technique documented in the other answer. The following pseudo-code shows the approach I'd use:

if (GetAsyncKeyState shows Shift is pressed)
{
   use SendInput to send { Tab key press, Tab key release };
}
else
{
   use SendInput to send { Shift key press, Tab key press, Tab key release, Shift key release };
}

How to Create and format partitions

Hi all,
I am creating an application for windows Vista, XP and 2003Server. In my application I need to create and format partitions(Extended and primary both). I do not want to use DISKPART utility. Is there any other way to do this job like by using any win32API or any function provided by Microsoft in MSDN?

Please give me some suggestions.

Thanks

Ya ofCourse, you can use DeviceIoControl codes. for creating any partition (primary or logical) IOCTL_DISK_SET_DRIVE_LAYOUT can be used. Big Grin | :-D

Thanks CMylife.

I am going to implement it now. I will consult you after trying it.

Its good that you are trying yourself. nothing you have to do. u first of all get the all partitions information by using IOCTL_DISK_GET_DRIVE_LAYOUT, then just edit the partition number, its offset, size and the last parameter , set that to true and finally run the IOCTL_DISK_SET_DRIVE_LAYOUT code from there itself. and then you are done with a new partition.

All the best.
