#Caché

All,

Recently, a Cache 2017.2.2 system started printing “28” rather than clearing the screen when doing a “W #” in programmer mode.

Does anyone have any idea how this could happen?

Hi,

I ran the Cache ODBC Driver installer as Administrator on my Windows 7 PC this morning. It completed successfully with o indication of any issues. When I check installed programs and features via Win 7 Control Panel, I see it listed as Intersystems ODBC Driver 1.00.000.

However, when I try to configure the driver via Control Panel - Administrative Tools - Data Sources (ODBC), I cannot find it. The only driver listed under the Drivers Tab is SQL Server.

I am not sure how to proceed.

I appreciate any suggestions.

Thanks,

Bill

In our language we have scandic letters like ä (a with two dots on it).

In Angular we use login like this:

let headers = new Headers();

password = Base64.fromBase64(password);

headers.append('Authorization', 'Basic ' + Base64.encode(username + ':' + password));

Hi,

Upgrade of custom application

Dear community,

we are a company located in central Germany working with Intersystems Caché since 2003 (Jesus, that's actually a long time in IT).

As we struggle to keep pace with outside development we still operate on Caché 2013.1

We are, of course, aware that we need to upgrade Caché and therefor plan an upgrade to 2017.2.

Is their a way to (setup) automate the removal of users accounts from the system once they have logged out of cache and than recreate them once they log in, so basically the user list only contains live logged in users plus some of the default user accounts.

I'm running this code in our application, and in the terminal:

>set query="SELECT * FROM PMG_Data_Private.RemitInstance WHERE (VoucherNumber %INLIST ? SIZE ((10)))"

>set tRS = ##class(%ResultSet).%New("%DynamicQuery:SQL")

>set ok=tRS.Prepare(query)

>d $system.Status.DisplayError(ok)

ERROR #5540: SQLCODE: -76 Message: Cardinality mismatch between the SELECT-list and INTO-list
SQLTEXT: SELECT * FROM PMG_Data_Private.RemitInstance WHERE (VoucherNumber %INLIST ? SIZE ((10)))

This code snippet provides a ZEN page that downloads a stream from its database directly:

/// We assume that you have stored your data within this schema:
/// MyApp.Model.Storage: Filename,FileSize,Content,ContentType
Class zen.downloadStream Extends (%ZEN.Component.page,%CSP.StreamServer)
{
 
    /// Wrapper to get the id of the download, we assume that the id is passed to this zen page
    /// as a URI parameter, i.e.: MyApp.Downloads.cls?OID=1234
    ClassMethod GetId()
    {
        Quit $Get(%request.Data("OID",1))
    }
     
    /// Set the appropriate header for the file.
    ClassMethod OnPreHTTP() As %Boolean
    {
        Set tId = ..GetId()
     
        If ##Class(MyApp.Model.Storage).%ExistsId(tId) {
            Set tStream = ##Class(MyApp.Model.Storage).%OpenId(tId)
            // You could "guess" the content type by its file extension
            // or you can store it (before) in the database separately (like in this example).
            // Set Extension = $Piece(tStream.Filename,".",$Length(tStream.Filename,"."))
            // Set ContentType = ..FileClassify(Extension)
     
            Set %response.ContentType = tStream.ContentType
            Do %response.SetHeader("content-disposition","attachment; filename="_tStream.Filename)
            Do %response.SetHeader("Content-Length",tStream.FileSize)
        }
        Else {
            Set %response.Status="404 File Not Found"
            Quit 0
        }
        Quit $$$OK
    }
     
    ClassMethod OnPage() As %Status
    {
        Set Download = ##Class(MyApp.Model.Storage).%OpenId(..GetId())
        Do Download.Content.OutputToDevice()
        Quit $$$OK
    }
 
}

Hey folks,

I've shared a debug stack we created on the Open Exchange.

I want to post the link here, but need the link to this article for the Open Exchange. Which came first, the chicken or the egg?

Using our cool new debugging extension for Visual Studio Code I'm trying to debug a CreateProjection method of a class, but when I compile it the work apparently gets done in one of the worker jobs, so my breakpoint never triggers.

Is there a compiler flag or qualifier to force the compilation to be done in-process rather than getting handed off to a worker job?

Hello,

I have a question about creating properties with curl.

I already did create properties in Java with the following command.

<DO db.%CreateProperty("TotalSteps","%Integer","$.TotalSteps")>

It created the property TotalSteps with the type %Integer and the data path $.TotalSteps (since the header of my data source is also TotalSteps).

Now I would like to create the same property in curl with the following command
