Question

我现在可以使用VisM通过vb.net执行Intersystem Cache Objectscript

            'open the connection
        AxVisM1.Connect("CN_IPTCP:127.0.0.1[1972]")
        'set namespace to livedata (for formal namespaces, use the @ symbol)
        AxVisM1.NameSpace = "LIVEDATA"

        'okay, so kunin mo na si GLOBALS...
        'set value to nothing muna
        AxVisM1.VALUE = ""

        'next, get mo yung value via this syntax
        AxVisM1.Code = "Set VALUE=$GET(" & theGlobals & ")"


        'execute
        AxVisM1.ExecFlag = 1

        'close the connection
        AxVisM1.DeleteConnection()

        'now, pass the results to.. a textbox?

        Return AxVisM1.VALUE

你可以通过传递.CODE

来执行objectscript

现在，是否有一个可以使用的对象脚本可以模仿Intersystems Cache中 GLOBAL SEARCH MASK 的功能？如下图所示

编辑我尝试了以下操作将数据传递到我的数据表，但我的数据表没有任何内容

Try
        'open the connection
        AxVisM1.Connect("CN_IPTCP:127.0.0.1[1972]")
        'set namespace to livedata (for formal namespaces, use the @ symbol)
        AxVisM1.NameSpace = "LIVEDATA"

        'okay, so kunin mo na si GLOBALS...
        AxVisM1.P1 = "^BACKTR(""INDX"",""COMPANY"",)"
        'set value to nothing muna
        AxVisM1.VALUE = ""

        ''next, get mo yung value via this syntax


        AxVisM1.Execute("set tRS=##class(%ResultSet).%New(""%Global:Get"")")
        AxVisM1.Execute("set P3=tRS.Execute(P0,P1,"""")")
        If (AxVisM1.Error <> 0) Then
            MsgBox(AxVisM1.ErrorName)
            Exit Try
        End If

        'create the datatable

        Dim tbl As New DataTable
        tbl.Columns.Add("theGlobals")
        tbl.Columns.Add("theValz")

        'start the loop
        AxVisM1.P2 = "0"
        While True
            AxVisM1.Execute("set P2=0,P3="",VALUE="" if tRS.Next() { set P2=1,P3=tRS.GetData(1),VALUE=tRS.GetData(2) } ")
            AxVisM1.ExecFlag = 1

            If (AxVisM1.Error <> 0) Then
                MsgBox(AxVisM1.ErrorName)
                Exit While
            End If
            If (AxVisM1.P2 = "0") Then
                Exit While
            End If

            ' AxVisM1.P3 - globalName
            ' AxVisM1.VALUE - data
            tbl.Rows.Add(AxVisM1.P3.ToString, AxVisM1.VALUE.ToString)


        End While
        'close the connection
        AxVisM1.DeleteConnection()


        'Return AxVisM1.VALUE
        Return tbl


    Catch ex As Exception

        'close the connection
        AxVisM1.DeleteConnection()

        MsgBox(ex.ToString)
        Return Nothing

    End Try

在这种情况下，您可以使用%Library.Global类和Get查询。在此查询中，您可以传递与第二个参数完全相同的掩码，并将获得全局名称和值作为结果。在Cache这样的代码可能看起来像：

Set Namespace = "USER"
Set mask = "^BACKTR(""DATA"",,)"
Set tRS = ##class(%ResultSet).%New("%Global:Get")
Set tSC = tRS.Execute(Namespace,Mask,"")
While tRS.Next() {
    Set gn = tRS.GetData(1)
    Set data = tRS.GetData(2)
}

在VB中就是这样的

    AxVisM1.P0 = "USER"
    AxVisM1.P1 = "^BACKTR(""DATA"",,)"

    AxVisM1.Execute("set tRS=##class(%ResultSet).%New(""%Global:Get"")")
    AxVisM1.Execute("set P3=tRS.Execute(P0,P1,"""")")
    If (AxVisM1.Error <> 0) Then
        MsgBox(AxVisM1.ErrorName)
        Exit Try
    End If

    AxVisM1.P2 = "0"
    While True
        AxVisM1.Execute("set P2=0,P3="",VALUE="" if tRS.Next() { set P2=1,P3=tRS.GetData(1),VALUE=tRS.GetData(2) } ")
        If (AxVisM1.Error <> 0) Then
            MsgBox(AxVisM1.ErrorName)
            Exit While
        End If
        If (AxVisM1.P2 = "0") Then
            Exit While
        End If

        ' AxVisM1.P3 - globalName
        ' AxVisM1.VALUE - data

    End While
