Problem with alignment of in memory dialog template

[titanandrews]

Hi All,
I have an existing app which creates dialogs from an in memory
dialog template using the CreateDialogIndirect function. I have a
working function that generates the controls for the dialog using the
class id for the control instead of the Unicode class name. But I need
to change this function to use the Unicode class name instead, because
I need to be able to create custom controls. I seem to be having some
difficulty with the alignment, because I cannot create the dialog
using the class name. Posted here is my function that creates all the
controls:

Notice that the section marked "//This section works" is the part the
uses the class id. The section I am experimenting with is //Begin new.
If the control id is 0x81, which is an edit field, then I want to use
"Edit".

Does anyone know what I am doing wrong here? Your help is greatly
appreciated.

many thanks,

Barry
