Reading Serial Data into a Word Document Using DDE
(This example is for 16 bit versions of Word Including Word 2.0 and 6.0)

1. Select "DDE Server" from the MODE menu and enter: WinWord as the Application Name and System as the DDE topic in the dialog box that appears and click the OK button.

2. Select "Input Data Record Structure" from the DEFINE menu and define the structure of the input records to the Wedge. When you get to the final Window entitled "Input Record Definition Editor", enter the string: [GRABDATA] as the "Field Postamble DDE Command" after the last data field that you have defined. This is a DDE command that will be sent to Word after each data record is received by the Wedge.

3. Set up the rest of WinWedge parameters and activate it.

Steps for setting up Word

When you create a WordBasic macro or subroutine in Word and save it in the Global macro sheet, the name of the subroutine automatically becomes a valid Word DDE command. Create a new macro by selecting "Macro" from the TOOLS menu. When the dialog box appears prompting for a macro name, enter the name: GRABDATA and then click the button labeled "Create". Enter the following code in the macro editor window:

After you are done entering the code select "Close" from the FILE menu to save the macro.

This example sets up the Wedge to issue a DDE command ([GRABDATA]) to Word after each data record is received from your serial device. This causes the GRABDATA subroutine to run which then performs a DDERequest back to the Wedge asking for the data in Field(1) in the Wedge Window. This data is returned to Word in the variable: MyData$. Once the data from the Wedge is in a variable, you can do whatever you like with it by including additional code of your own design. This example simply inserts the text in the MyData$ string variable into the open document and then inserts a paragraph marker.
