Hi All!!!!,

Please Help me!!!!!

I am having a problem to set enum value with out using the enum type.

For example, normally we set enum field's value as - Table.fieldName = str2enum(EnumType, "string"); (or) Table.fieldName = EnumType::Element;

But I need to set the enum value with out using that EnumType, Whether it is possible!!!!

Thanks in Advance!!!

Regards,

Deepak M

So what information do you have about the value? A string representation?

And where do you try to assign it to? In case of a field, you can get EnumType from field's properties, can't you?

Not sure if this is what you are trying to do, but since an enum is basically an Int value, the compiler will let you set Int values. As an example, the below code, though probably not recommended, works.

ABC enumABCVariable;

;

enumABCVariable = 1;

// or

enumABCVariable = global::enum2int(ABCModel::ContributionMargin);

If "without using that EnumType" means to set the value of a different enum, the above code should do the trick to get you past the compiler. Of course if a invalid value is set, you will probably get bad results at runtime...

I think that what Deepak M wanted to ask, was that in the need of using str2enum, how can we pass the first parameter without hardcoded enum type, but instead, by using some enum name or enum id (i.e. do it all in dynamic) ?

I still wonder if it's possible...

Maybe such an example might help ?

static void TestEnum(Args _args)
{
    str         label = "Ventes";   // French word for "Sales"
    EnumId      enumId = 281;       // My system Id for SalesPurch enum

    SalesPurch salesPurchIn;
    SalesPurch salesPurchOut;

    DictEnum    dictEnum = new DictEnum(enumId);
    int         numEnum;
    ;

    // Test 1: we have a variable of desired Enum type (salesPurchIn of type SalesPurch), we can use the str2enum function
    salesPurchOut = str2enum(salesPurchIn, label);
    info(int2str(salesPurchOut));

    // Test 2: we don't have any variable, but we know the EnumId
    numEnum = 0;

    while(numEnum < dictEnum.values())
    {
        if(label == dictEnum.index2Label(numEnum))
        {
            info(int2str(dictEnum.index2value(numEnum)));
            break;
        }

        numEnum++;
    }

    // Test 3: we can do it with name2label anyway...
    info(int2str(dictEnum.name2value(label)));
}
