Well, maybe I did not make myself clear... Let me try to explain it better this time:As I see it, any "Function" , in any language, is "a program (or whatever)" that can be invoked from another program (Application) to do some work and return a result value. What I'd like to write is a "Function", could be called "Ask_Customer_ID", that would present some displays (windows) with search criteria, show a list (ListBox) of those that qualify for the entered search criteria, allow for selection, and return the selected Customer_ID. Any Access Form that needs the customer_ID (Order Entry, or Invoicing, etc) asking the user for Customer_ID could then have a "Command Button" that, when pressed, would call Function Ask_Customer_ID" to get it returned and go on with other processing...
That function (and, possibly, others...) could be "encapsulated" (???) in a .DLL to be used "where needed".
Can this be done? Any example of how to do it?But from Access2000 Help (and I guess Access2003 would be the same...) searching for "Call" (Action Execute Code):
"Microsoft Access ignores the value returned by the Function" (??? !!!) Then, maybe, passing the Customer_ID as a ByRef parameter? Hope I made myself more clear this time. TIA Shannon ODonnell escribió:
So...I'm not following this completely here... are you wanting to have a customer number (and all key fields) prompt that then writes the values to a file which could be read by your Access and other apps? And you're wanting it such that from within Access or Excel or whatever, you can execute this new app to display the prompt. And your goal is so that the single prompt provides a uniform look and feel to all the apps, writing the data to a single file on the hard drive? Is that what you're after? -----Original Message----- From: pctech-bounces+sodonnell=irish-studios.com@xxxxxxxxxxxx [mailto:pctech-bounces+sodonnell=irish-studios.com@xxxxxxxxxxxx] On Behalf Of Antonio Fernandez-Vicenti Sent: Friday, June 09, 2006 8:58 AM To: PC Technical Discussion for iSeries Users Subject: [PCTECH] VB/Delphi "kind of" Service Program_DLLCustomer is using Access/2003 for several apps. Several of them start asking for something like "Enter Customer Number", so we'd like to just implement such a Function just once and have all initial Forms for each app, when users is promted for "enter CustomerNo" either answer with a number (if he knows it) or , else, press F4 (or whatever, or a Button) to "call a Function" that will do the work: e.g. present a new Form asking for key values (LastName starting chars, FirstName starting chars, CityAreaCode, etc. Then show customers that fulfill those requirements, allow for selection of one of them , ... just to return the selected code or a "not found" value... to the original App.Such a Function would be used throughout in several different Apps. I think one (best one???) of the alternatives would be to develop a "CustomerSelect Function, receiving no-parms, returning one integer(or zero, maybe) value of selected CustomerCode. This Function could/should be writen either in VB or Delphi, then create a .DLL with that Function, to register under Windows, to be used for any VB projects that need it.I think of it as a "ServiceProgram" in RPG... but as a DLL.Anyone out there willing to share an example (either VB and/or Delphi) of such a Function?TIA Antonio Fernandez-Vicenti afvaiv@xxxxxxxxxxxxxx
