*****************************************************************
I have encountered a problem with the "DDERequest" procedure from
MS-Test's DDE dynamic link library. I'm using the command to communicate
with a self-developed application acting as the DDE server.
This application accepts a series of requests, most of them work together
well with the TestBasic client.
However, a few requests (although processed correctly by the server) constantly
result in a runtime error ("A request for a synchronous data transaction has
timed out"). I have executed these requests from other client applications
successfully, even a WordBasic implementation worked alright.
The code sample below shows one of the faulty DDE requests:
result$ = string$(16," ") ' data buffer
itemstr$ = "Person.numKbz.isSelAt[1]" ' asks the server, whether a specific
' line (#1) of a multi-line screen
' item ("numKbz") is selected or not
dummy% = DdeRequest(_GLOB_DDE_HANDLE, itemstr$, result$, len(result$),
CF_TEXT)
Environment:
Compaq Deskpro XL 590 PC, Windows 3.1, MS-Test v3.00a
QUESTION:
I would like to know if there are any known DDE-conversation related problems
with MS-TestBasic and even more how to get rid of them.
Thanks in advance,
Peter Schiehl
