I have actually lost the original source of this code. I copied it along time ago from a tutorial written from Microsoft on how to write a specialized combobox. It had both C# and VB examples. I now believe the VB was converted from the C# with out much thought and the conversion was not actually tested.

Thanks Sergey for your input. The(0) on the end of Decimal.GetBits(18446744073709551583D)(0) I was referring to the low 32 bits because I felt this was the authors intent to narrow from the wider ulong flag for the binary operation. The CInt(Me_flags) simply will not work as intended in VB. I had not considered using System.BitConverter, I'm studying this now. Thank you.

Thanks for the reference. This is part of my confusion. The flag is a ulong and can have a value like 18446744073709551583 which converts to a decimal -33, works fine in C#. But in VB if you try "i As Integer = CInt(18446744073709551583UL) you get an overflow error. So you have to use something like Decimal.GetBits(18446744073709551583D)(0) which gives you the low 32bits of the 96 bit Integer. I agree the code is horrible, just trying to understand why it is written this way.

Sergey, everyone knows how smart you are and your answers are quite helpful to me. But I felt like you were just in a bad mood. All I wanted was some insight into how the flag value was being used in those lines of code. It seemed like a "magic number" at the time.

Thanks for your solution PIEBALDconsult. This pointed me in the right direction and I understand how that section of code is used now.

Thanks Sergey, I forgot that you know it all. I'll make sure that I learn everything before I ask my next question. Maybe this is why most beginners have so much trouble asking questions. Because there's always someone like you ready to ridicule them instead of HELP them.

It was written by Microsoft, but if you have any REAL input that would be helpful.
