Reads a line of text from a DDE Conversion, for example, from an Excel spreadsheet. You need to first start a conversation with the DDEhInitiate function, and use the handle returned by that function to identify the conversation. This function allows you to read a large amount of data via DDE. Keep calling the function until an empty string is returned to verify that all the data has been read.
This function is a blocking function. It will block the calling Cicode task until the operation is complete.
