Saving data from form.

[akki123]

Hi,

I took the reference of the following link.

http://www.developer.nokia.com/docum...Form_API4.html

ok as per this link when i fill the from in the editable mode & after that when we press back or Save button it will call the function SaveFormDataL();

Now as per the code we have:--

CEikEdwin* user =
(CEikEdwin*)Control( EMyAppControlIdTextEd );
TDes& aUser;
user->GetText(iData.iName);

it means we have the control(pointer) in the row with id - EMyAppControlIdTextEd ;
ok

now when we call
user->GetText(iData.iName);
The whole content of the row will be copied to the iData.iName.
if data is saved this function will return ETrue.

Am i wright? Please suggest if i understood any thing wrong.

when in from my Function after filling the data i put the check

if( SaveFormDataL())
{
//launch other screen.
but i am getting error at this point.
}

Please help/

Basially the Control returns a pointer to CCoeControl type instance, then you cast it to the correct control type, like in this case you cast it to CEikEdwin. So you could simply check SDK docs for the CEikEdwin to see what functions it implements and what they do.

For the error, you would need to check what it is actually and then copy the description in here. Also do mention whether its compilation time error, or run time.

Its a run time error.

after executing the form i got:->


CDesCArray* array = new (ELeave) CDesCArrayFlat( 8 );
CleanupStack::PushL( array );
array->AppendL( _L("January") );
array->AppendL( _L("February") );
array->AppendL( _L("March") );
array->AppendL( _L("April") );
array->AppendL( _L("May") );
array->AppendL( _L("June") );
CAknQueryValueTextArray* textArray = CAknQueryValueTextArray::NewLC();
textArray->SetArray( *array );
CAknQueryValueText* queryVal = CAknQueryValueText::NewLC();
queryVal->SetArrayL( textArray );
queryVal->SetCurrentValueIndex( 0 );

TMyData myData;
myData.iAnswer = _L("");
myData.iConfirmPass = _L("");
myData.iPass = _L("");
myData.iName = _L("");
myData.iQuestion = _L("");

CAknForm* dlg = new ( ELeave ) CMyForm( myData );
CleanupStack::PushL( dlg );
dlg->ConstructL( 0 ); // default menu items only
CleanupStack::Pop( dlg );
dlg->ExecuteLD( R_MY_DIALOG );
CleanupStack::PopAndDestroy(queryVal);

and after this i filled all my data & pressed save.

When i am calling
if(SaveDataL)
{
}
in the line if(savedataL) i am getting the error.

Any error/crash code visible while running this code?

I can not imagine how that example survives. These ancient casting magics are really nice, but a thing you may rather want to try is the setter-getter method pairs inherited from CEikDialog, methods like Get/SetEdwinText, like a call

GetEdwinText(iData.iName,EMyAppControlIdTextEd);

for storing the editor contents of field "EMyAppControlIdTextEd" into iData.iName.

I tried the get set method. But still getting the same error.

Ah, now I noticed "but i am getting error at this point." in the first post. You probably know the things will happen now, questions will come like "what is the error code", perhaps someone will post a link to http://www.developer.nokia.com/Commu...ded_panic_code
