1) dumpbin /exports filename.dll
2) Look up LoadLibrary() and GetProcAddress()

OnKeyDown()

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

hi!!

I am trying to port code from VC 6 to VC8. But while compiling i am getting erros like this:

error C2440: 'static_cast' : cannot convert from 'void (__thiscall CKPActivatorDlg::* )(WPARAM,LPARAM)' to 'LRESULT (__thiscall CWnd::* )(WPARAM,LPARAM)'<br />
None of the functions with this name in scope match the target type<br />
......

As error indicated..I changed the return type of function from void to LRESULT. Also I am returning 1. Although its working 4 me,I am not sure whether this is the correct sol'n to the problem or not!

plz help!

Thx in advance!

Try these changes in the current project.

1)Return HRESULT instead of void
2)Is CKPActivatorDlg derived from CObject derived class ??If not do so.

You get C2440 cannot convert void to LRESULT and its a error how do you run your program

31-Jul-06 2:05

That is what i done!!
I changed the return type to LRESULT; and returning value'1'

So now my project is getting compiled successfully. But I am not sure whether thid is right solution or not!

Thx!!

are you compiling that in which compiler? VC6 or VC7

Hi,

I am using MSXML4.0 with VisualC++ 6.0.

when I try to load and search nodes using selectSingleNode()from an xml having the default namespace like

<hari xmlns="....">

this function is returning NULL always

but if I put a prefix like this

<hari xmlns:pr="...">

the function "selectSingleNode() is retuning correctly.
what is it so ?

since I have an application which loads external xmls which may or maynot contains the namepace prefix how can I solve the probelm with selectSingleNode()...

thanks in advance
