Not able to create CAknIntegerEdwin/CAknNumericEdwin

[gpalvia]

Hi
I have used the Wizard to create a Eikon Control application
and in the container i am using the following code in the ConstructL function to create a numeric control.

void CFourFebContainer::ConstructL(const TRect& aRect)
{
CreateWindowL();
iTelEdwin= CAknIntegerEdwin::NewL(0,101,20);
iTelEdwin->SetContainerWindowL( *this );
iTelEdwin->ConstructL(0,101,20);
SetRect(aRect);
ActivateL();
}

Is this the right way to create CAknIntegerEdwin control. As i get exception in ActivateL() function.

One more thing is that whenever i try to create CAknNumericEdwin i get a linker error.

Hi

I Think you shouldn't call construct function there at all, since the NewL is propably calling it already.

anyway what is the error note shown ?

Hi yucca,
Thanx a ton. Ur suggestion worked for me. Calling NewL and
then calling ConstructL was creating the problem. I commented the ConstructL and now its working.

but why I use CAknIntegerEdwin like that
...............................
TResourceReader reader;
iCoeEnv->CreateResourceReaderLC(reader,R_AKNINTEDITOR_GAMEVIEW_EDWIN );
iIntEdWin=new(ELeave)CAknIntegerEdWin;
iIntEdWin->SetContainerWindowL(*this);
iIntEdWin->ConstructFromResourceL(reader);
CleanupStack::PopAndDestroy();

...................................
while there the errors are all " illegal use of incomplete struct/union/class 'CAknIntegerEdWin'" but Ihad include"aknnumedwin.h"
what can I do to get it rigth?

Make sure that the #include actually succeeds, preferably with <>. If you happen to use the Symbian^3 SDK, note that aknnumedwin.h might have been relocated into some sub-folder of epoc32\include, in that case put the folder in question amongst the SYSTEMINCLUDE paths.
