Passing the workspace as a parameter

Parameter to choose workspace used

Previously in VDF 11.1 I have created and compiled programs on my development machine with local data on drive C:and a workspace called "Garments". When publishing the program for network use, I have passed a parameter to the application "Netgarments" and have had a separate "Netgarments.ws" file which stated that the data path was on drive F: - the network drive. Thus when using the App on the network, users saw data on drive F:

How can I do this with the new workspace system in VDF12.x and beyond?

Changes in the cApplication class

With VDF12 the workspace logic has changed a little. Previously in VDF8.x .. VDF11.x the configuration of your workspace was partly stored in the registry and partly in the .ws file. Now with VDF12.x (and later) the registry settings are gone. The settings are now stored in a .sws file along with one (or more) .ws files.

In order to select the correct .ws file, the cApplication class now has a property called

psAutoOpenWorkspace

and its default is

config.ws

which is the name of the default .ws file. If you want to use your old .ws file, just change the value of that particular property.

An Example of a program that uses a subclass of cApplication

the program:

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

//AB-StoreStart Use dfAllEnt.pkg use DFAbout // #REPLACE CURRENT$WORKSPACE   "Training.Mapps121" //default - modified by calling param Register_Object oClientArea // // 1) use package for application workspace Use MyApplication.pkg //Workspc for multico workspace mapps121 // // 2) Set date attributes as needed Set_Date_Attribute sysdate4_State to dftrue Set_Date_Attribute Date4_State    to dftrue Set_Date_Attribute epoch_value    to 60 // // 3) Application Workspace - help type and name Object oApplication is a cMyApplication End_Object  // oApplication //etc
