Hi all,

I have a dynamically add excel column based on a data types.

Below code works good if its number. but if that enum element name getting error.

case Types::Enum:
if(str2numOK(columnVal.Value))
{
    Trans.(fieldName2id(Trans.TableId,columnsFields.AxFieldName)) = any2Int(columnVal.Value);
}
else
{
    Trans.(fieldName2id(Trans.TableId,columnsFields.AxFieldName)) = enum2Value(columnVal.Value);
}

As i mentioned above code is 'Else' part getting error:

Function Global::enum2Value must be called with an enumerated text type.

How to deal with Str2Enum function give me a solution for this.

Thanks

Hi waytod365,

As error stated that, you need to convert string to enum value before passing it to enum2Value method.

Code should look like below.

//declare variable for your enum.

YourEnumName enum1;

enum2Value(str2enum(enum1, columnVal.value));

Thanks,

Girish S

Thanks for your prompt response Girish,

Actually i wanna dynamically enum in the else part. I don't wanna specific enum variable. As you mentioned above code is dynamically? Can you tell the variable name?

Thanks

So in the excel you will have multiple enum elements. It may not be same enum for all the rows.

In that case just use any2Enum method.

enum2::value(any2Enum(columnVal.Value));

Add the any2Enum(columnVal.Value) to info log and check whether its returning any value.

Also check the string thats coming from excel is a valid enum elements.

What is the value you given in the excel? I mean what is the value for columnVal.value.

Does the value exist in any of the enum elements?

Thanks,

Girish S.

If I understand it correctly, you need symbol2Enum(), not enum2Value(). Use DictField.enumId() to get the enum ID for the first argument:

SysDictField dictField = SysDictField::newField(tableId2Name(trans.TableId), columnsFields.AxFieldName); trans.(dictField.id()) = symbol2Enum(dictField.enumId(), enumValue);
