Re: KeyBoard mapping
Actually my problem is...I made a keyboard with some bitmap and i
incuded this in to Dialog and i name it as KeyBoard.cpp.
THe keyboard has the same resemblance of system keyboard.
I included some dialogs to enter the values and performing functon as
normal dialog...Instead of using our system keyboard to all purpose..I
am using that Keyboard in applivation. Normally if i entered the number
1 in system keyboard then that normal dialog named as simpledlg.cpp
file.The simpledlg edit control accept my value.
At the same time if press number 1 in my application keyboard the
number is not get in to that simpledlg edit control.I think now u get
my problem.
FOr that my coding is ..
In Keyboard.cpp...For each button,I wrote like this..
void CKBoard::OnLButtonUp(UINT nFlags, CPoint point)
{
CView *curView;
CMDIFrameWnd *fWnd = (CMDIFrameWnd*)AfxGetApp()->m_pMainWnd;
CMDIChildWnd *fChWnd = fWnd->MDIGetActive(&bMax);
if(fChWnd->GetSafeHwnd())
curView = (CView *)fChWnd->GetActiveView();
else
curView = NULL;
switch (keyvalue)//number of keys in keyboard
{
case 51 :
if (curView)
curView->PostMessage(WM_KEYDOWN,49,0);
break;
case 52 :
if (curView)
curView->PostMessage(WM_KEYDOWN,50,0);
break;
case 53 :
if (curView)
curView->PostMessage(WM_KEYDOWN,51,0);
break;
case 54 :
if (curView)
curView->PostMessage(WM_KEYDOWN,52,0);
break;
case 55 :
if (curView)
curView->PostMessage(WM_KEYDOWN,53,0);
break;
CDialog::OnLButtonUp(nFlags, point);
}
In simpledlg.cpp class i wrote OnKeyDown function to accept this
coomand..
void CFaceDlg::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
switch(nChar)
{
case 49:
sSktNumValue += "1";
break;
case 50:
sSktNumValue += "2";
break;
case 51:
sSktNumValue += "3";
break;
..
..
..
..
}
Please find out my problem

Few days back i posted here the same problem.I want to get some answers
pls help me.
In the application one keyboard is made by using a dialog with
bitmap.Then by pressing the keys in that keyboard the application will
get data like numbers,alphabets,enter key...like that.This keyboard
have all buttons like the system keyboard.
I have to enter values to dialog edit control through this keys.So i
get sample coding..In that they coded in keyboard class
like..PostMessage(WM_KEYDOWN,49,0);
and in the corresponding dialog class where the value should entered
they coded as
void CFacePlate::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
case 49:
sSktNumValue += "1";
break;
CDialog::OnKeyDown(nChar, nRepCnt, nFlags);
}
So i debugged the program..When ever the Postmessage function in
Keyboard class is executed then the contol is going to OnKeyDown
function in Dialog class.How it si going there?
I dont know whats happening there.
I coded like this for my application..but the control is not going to
OnkeyDown function..How can i make that?
i did not follow your problem properly. From what I have grasped, You
intend to use or detect the keys pressed...is it not? Then why dont you
override and use PreTranslateMessage funtion instead? Regarding ur
controls not going to the OnKeyDown function that you have
defined...have you included its message map. It happens a lot of times
with me when i sometimes forget to include a message map.
