PFC Sort vs. PFC Linkage
I have a datawindow which I used the PFC Sort service on, only to use the
column heading type sort. This worked fine.
Then I set up the same datawindow to use the PFC Linkage service, using the
filter feature. This particular datawindow was the master. Now the linkage
filtering works but the column header sort no longer works. I commented out
the linkage code and then the sort works. Are both of these services not
meant to work together?
...To PFC or Not To PFC
I'm returning to PB development after about 7 years in management and
I'm trying to figure out how PFC fits into the current PB world. I
used it with 6.5 and thought it was great (though sometimes a little
complex, especially when debigging). It seems that Sybase doesn't
push it anymore and I think I saw a post that said it hasn't changed
I'll be developing an app for commercial sale and I think PB is
perfect since I think I can get more done in a shorter period of time
with PB than with anything else. I especially like that PB's future

I am about to start a very big application and would like to know whether
to use PFC or not. Is it not a good idea if we are only using a very small
portion of the PFC functionalities?
What are the benefits of using PFC? What are the disadvantage of using it?
We already have development problem because it is too slow to bring up the
object and window list in the dubugger.
To Use or Not to Use? I dont have an answer for you there but, a solution to
your speed of the debug issue is the following. We have found that keeping
copies of the PFC, PFD, and PFE p...PFC Linkage
If I am assigning the key for the master DW in the pfc_preupdate event, how
do I utilize the DataWindow linkage service to update the detail DWs. I am
getting a Null value unless I specifically set the item in the detail
I m using this approach (with autoincremented keys)
calling these functions in the updateend event of the master datawindow
this is juss a guideline you can evolve it in your own way.. if get into
trouble.. pls ask me.

Is anyone out there developing an EAServer-based application with a
PowerBuilder/PFC front-end? In the client-server days, we could depend on a
database connection being around typically for the life of the application.
This worked great for PFC applications, as much of the PFC relies on this
connection. With the advent of EAServer and n-tier, however, we are
supposed to develop middle-tier functionality that connects to the db only
as needed and only for as long as needed. We are having a problem
integrating the PFC (with it's dependency on the db) with middle-tier
components d...pfc linkage problem
I have a window with one tablular form dw which gives the "reader's digest"
version from a large database table. I am going to set up a u_tab user
object with several freeform tabpages to reflect the "unabridged" detail
from the same database table. Right now i only have one tabpage in the user
object until i can get the "reader's digest" (dw_master) to sync with the
one tab page when i scroll to the row in the master dw. Right now i can't
get it to sync. I have 6 rows of data for testing and each time I scroll to
another row in dw_master th...PFC Linkage Service
I'm having some trouble using the Linkage service. I have used this
before on Master/Detail windows by using of_SetUseColLinks(2)
(retrieve). But when I try to filter, of_SetUseColLinks(1), I can't get
it to work. What do I have to change to use filtering? I'm also using
the CornerStone extensions if that makes a difference. Thanks in advance
for any help!
Not really sure about the CornerStone. What exactly is not working? Are the
of_setarguments() in sync as far as the column names for both dWs?

Can anyone who has experience using PowerBuilder, PFC, and PVCS give me
some insight into the best way to set up a shop where multiple developers,
working on multiple applications, are using the same copy of the PFC
Are the PFC objects versioned under a separate PVCS project database, or
under each application, or??
Do you utilize the promotion model facility available in PVCS? If so, how
do you implement it?
Thanks for any help you can give.

I ran into a problem with the PFC Linkage Service and I just want to see
if this problem can be confirmed by someone else.
I am using the PFC Linkage Service to link 5 datawindows. One is the
master. The method of link is 2 (retrieve). Because the retrieve for
all the linked datawindows are slow, the scrolling of the master
datawindow slows down to a crawl. To get around this, I thought I could
link, refresh the linked datawindows, and unlink again. This seem to
fix my problem except after I do this a few times, I get an "array out
of bound" error.

Anyone know where to find information, how to build distributed

I think you are looking into one of those support gaps. I had no luck finding
someone who know both areas when I built my first application.
The connection_begin/ _end events for the PFC application objects is where the
CREATE/DESTROY for the APP-MANAGER needs to be. This is needed to get
addressing to work - each session is in its own work-space. There are no
indications of this anywhere other than searching PB's ...PFC linkage
PFC linkage service - deleting
One more question on th elinkage service...
Now I am trying to delete a row in the master and the associated detail
rows. I call the pfc_deleterow(ll_row). I get an error message indicating
a DB constrain violation due to a foreign key between master/detail. Why?
Before I delete I set the update style to BOTTOMUP (..or is does this
function only works for updates???) so that my detail gets deleted first:

...PFC Linkage Service
I'm using the PFC linkage service fro my master and detail datawindows. I
had thought that the id of the master would automatically get set in the
detail when I call pfc_save but that is not happening. Do I need to set
the foreign key in the detail in the pre_update event or am I not setting
up the linakge service correctly?
This is the code that sets up the linkage service:
//Setup the linkage service
I am using PFC 5.0.2 and have two u_dw controls linked on the same window.
They work fine except for during the initial retrieves. The master dw
displays its rows fine, but since the current row is one I would expect the
detail dw to show the corresponding rows for row one. It does not. If I
change rows or add a row and change back to row one it works. I tried
various means of coding around it, such as sending a pfc_rowfocuschange
event, etc. The of_retrievedetails() function in n_cst_linkage looks
promising but it is protected...
Any help would be greatly appreciated.
