The WTX file is a plain Unicode text file. To create this text file, use
the Save As feature in Notepad, and select the Unicode format. This file is
similar to the old TPL file. Its format allows you to control where the
various fields are positioned on the screen, as well as the behavior of the
input fields, for example, default value, read-only, required, etc. All of
the op-codes are found on the Microsoft Exchange SDK.
For example,
0, 0, 0, 0, DTCT_PAGE, 0x00000000, 0x00000000, 0,MCI User
12, 50, 20, 8, DTCT_LABEL, 0x00000000, 0x00000000, 0,Alias:
75, 141, 18, 12, DTCT_EDIT, 0x00000006, 0x3001001E, 30,*
-or-
Once the WTX is complete, you need to compile it with a tool included in
the SDK. This tool is called Template.exe. It takes the WTX file as input
and outputs a BLT file.
Now you can verify the location of the different fields by importing the
file into the one-off address container. Create a CSV similar to this one
and use the directory import tool to bring it into exchange.

After you verify the field positioning, etc., you are now ready to create a
binary file that will control how the various fields will be processed. The
SDK suggests using DEBUG for this task. However, Dev Studio is a better
choice, specially if you plan to make any editing changes. In most cases
you take the information entered by the user and concatenate it into a
single address line.
For example, in Microsoft Mail for PC Networks, you would take the network
name, postoffice name, and the user ID and concatenate them using '/' to
separate the various parts of the address. Within this binary file you need
to specify an offset to locate the various text characters that are
inserted when completing the address. It is easier to use locate all this
type of text fields at the beginning of the file instead of at the end, so
your offsets do not keep changing. In order to make this work you need to
put a JMP operand (00 00 00 03) as the first instruction and indicate the
offset of where the program starts.
If you run debug or Dev Studio, you will notice that the actual program
does not start until 6A (hex).
