EnumHelper

Could I use the EnumHelper to do this test?

I don't think so because a System.Type is not an Enum.

Okay, Thanks. I thought I was missing something.

However, I'd rather compare the System.Type to Progress.Util.TypeHelper:GetType ("System.Decimal") .

You can try

TYPE-OF(Column:DataType, System.Decimal)

You can try

TYPE-OF(Column:DataType, System.Decimal)

Won't work.

This would check if a System.Type (whatever sticks in the DataType property is a System.Type instance) is a subtype of System.Decimal - and that will always return false.

Oooops, should be

TYPE-OF(Column:Value, System.Decimal)

Oooops, should be

>

TYPE-OF(Column:Value, System.Decimal)

At least for the Infragistics Grid that won't work: A Column does not have a value. A Cell has. But that might not be available without data.

TypeHelper:GetType () is the way to go.

You are correct. Just be careful with the casing as GetType will fail if the case is wrong.

In this case, I prefer;

IF oColumn:DataType:ToString() = "System.Decimal" THEN

You are correct. Just be careful with the casing as GetType will fail if the case is wrong.

Unfortunately that's true. It's bad that we have to pass in a quoted Type name.

If you want this changed, complain about this whenever you talk to someone from PSC. We need a typeof function as in C# (no dash here) where the attribute is validated at compile time and respects the USING statements as well.

A great way to discuss you needs to the language and tools with top Progress people (such as "Ms. GUI for .NET" Shelley Chase and "Mr. everything else" Ken Wilner).
