Hi Pooja, the PRIM_JSON.Document SaveToFile method expects a TextWriter reference to be passed to it. This is a #PRIM_IOC.StreamWriter, which itself needs to have the Stream set to a PRIM_IOC.FileStream


Define_Com Class(#prim_ioc.FileStream) Name(#OutputStream) Fileaccess(Write) Filemode ...

There is no browse button, and manually typing/pressing save does not update the tree on the right, so you might be confused and think nothing has saved. However when you close and reopen the webpage the icon you typed be shown in the tree. You need to manually set the size too (dont forget the icon ...

Hi Dino, did you uh, add a schema property like it suggests?

An object is a JSON object, a collection of String, Number, Array properties lumped together. It is not an object until it has at least one property.

A base64 string encoded file would be a string type property in your object.

Hi marcel.heij and pkoopmanpk

Jyoung left out a vital argument in his instructions for enabling debug :)

The correct line would be
"x_run_args": " DBUG=Y DBHT=computername:debugport"

Ensure that your webserver is configured to allow interactive debugging (Web Administrator, Connect, Configure ...

SAML is indeed a complicated beast.
I was looking at what pre-packaged solutions are out there when i found this site: https://medium.com/the-new-control-plane/i-need-a-saml-stack-now-63d9691e2d43

One of the solutions i looked into was OpenSAML (for Java), but it seems that original article was ...

I think you answered your own question with the point about the user/password.

Typically an interaction with a webservice requires passing an API key, or user credentials etc, which is why you would normally do them on the server side (so that the client has no way to see them). Also, the source ...

Since the spin edit is a material design control, i believe those arrow signs are fixed size icons (to keep with the material design guidelines i guess)

When you drag a field onto a PRIM_MD.List, by default it is added as a label (not an input field). If you look at the source code you will see it has a class #PRIM_MD.ListLabel. At design time it shows the field name, but at runtime it will be populated with the value of that field in the list. If ...

SAML isnt natively supported but could be implemented via a third party object (i.e. dot net control).

Also, the latest EPC (EPC142060) ships a sample via the Package Manager which shows how to use OAuth2 verification via Google/Facebook/Microsoft. The sample itself fairly complicated RDMLX code ...

I just spoke to Taku about this; he is attempting to call LANSA.Init() and LANSA.showPage() internal functions manually, rather than using the generated HTML page that LANSA creates (he took that documentation page to indicate that its fine to do this yourself).
He was hoping that if he passed ...

Once you do sys_web.Navigate you are out of VL Web, and you are just viewing the image in the browser. On Android (Chrome) you are able to zoom and long press on the image to save it. I suspect you are using an iPhone, and that Apple in their infinite wisdom decided to disable such functionality.

I ...

Hi Paul, are you getting some sort of error when you are trying this out? If i set the style of a grid cell, i can then retrieve it again without errors.

The issue might be that you have set the VisualStyle of the entire grid, and some specific cells in the grid... If i query the VisualStyle ...

I am often told i am a chronic optimist, but I am still confident that LANSA's future is bright. There are certainly a few people leaving, but from what i heard they are doing so out of their own decisions. Sencha was a startup company with lots of unnecessary expenditures and staff - LANSA is a ...

Joe, when you compiled the file without the drop table option (as per that last pic), the rebuild table/indexes options would have failed/skipped because the tables already exist. But the OAM would have been replaced (this overwrites regardless). So you have a situation where the database table ...

Sorry if that part wasnt clear! The setting for leading zeros is one that is often overlooked - it is from back in the days of Functions and Processes; VL Web honors the setting, but it isnt all that intuitive to find.

1. The placeholder issue is fixed in the latest EPC (EPC142030). The field will need to have ASQN attribute, and the placeholder will be shown when the field value is *SQLNULL
2. Leading zero display is configured through the System setting under System Information/Display and Print controls/Show ...

Hi Sotiris

Just to add to Dominique's response, it is a good idea to make sure that the entered date is a valid one, before executing the AsDate intrinsic function - otherwise you will get a runtime error with that code

If ( #InputDate.IsDate( CCYYMMDDD ) )
#OutputDate := #InputDate.AsDate ...

Yes, you can, and probably should use Material Design even for desktop only applications. The look you will achieve is similar to (but not exactly the same as) Windows 10 applications. This is a general design direction for all applications now, not just mobile.

Of course you are not restricted to ...

There was a new feature shipped with V14 SP2 which was not given much fanfare.... Repository field validation for VL Web applications. This allows you to check a field/fields against the field and file level rules defined at the repository level. Currently this feature is available for Prim_MD ...

Hi David, indeed the MSI installer (which we have been using since V13) uses the Microsoft recommended installation folder for applications, which is either:
c:\users\{logged on user}\appdata\local\apps\{company name}\{App description} for a "Current user only install"
or
c:\Program Files (x86 ...
