[metosrs]

Hello,

I want to use QueryWinL, but when I try to use it, my application is close. compilation is OK. My application use the camera and when user take snap I want display the message box
I have try :
TBool value = iEikonEnv->QueryWinL(_L("text"),_L("Continue?"));
and this line too:
TBool value = CEikonEnv::QueryWinL(_L("text"),_L("Continue?"));
and this too
TBool value = CEikonEnv::Static()->QueryWinL(_L("text"),_L("Continue?"));

with CAknGlobalConfirmationQuery, initialisation failed
CAknGlobalConfirmationQuery* temp = CAknGlobalConfirmationQuery::NewLC();

could I use this function in particular class?

I have forgotten to add library!! Carbide dont say, that he cant compile the .exe and he used the old .exe ... Finally I have use this code :

//create yes or no message box
CAknGlobalConfirmationQuery* pQ = CAknGlobalConfirmationQuery::NewL();
CleanupStack::PushL(pQ);


_LIT(KQuestion, "message display?");

TRequestStatus theStat = KRequestPending;
pQ->ShowConfirmationQueryL(theStat, KQuestion, R_AVKON_SOFTKEYS_YES_NO);
User::WaitForRequest(theStat);

CleanupStack::PopAndDestroy(pQ);
//get respons of mesasge box
TBool answer = (theStat.Int() == EAknSoftkeyYes);


if(answer)
{
//key press is OK
}
