GetCharArray - Character array from Automation server

Synopsis

MATLAB Client

str = h.GetCharArray('varname', 'workspace') str = GetCharArray(h, 'varname', 'workspace')

IDL Method Signature

HRESULT GetCharArray([in] BSTR varName, [in] BSTR Workspace,  [out, retval] BSTR *mlString)

Microsoft Visual Basic Client

GetCharArray(varname As String, workspace As String) As String

Description

str = h.GetCharArray('varname', 'workspace') gets the character array stored in varname from the specified workspace of the server attached to handle h and returns it in str. The values for workspace arebase or global.

str = GetCharArray(h, 'varname', 'workspace') is an alternate syntax.

Examples

This example uses a MATLAB client.

h = actxserver('matlab.application');
%Assign a string to variable 'str' in the base workspace of the server
h.PutCharArray('str', 'base', ...
    'He jests at scars that never felt a wound.');
%Read 'str' back in the client 
S = h.GetCharArray('str', 'base')

This example uses a Visual Basic client.

Create the Visual Basic application. Use the MsgBox command to control flow between MATLAB and the application.

Dim Matlab As Object
Dim S As String
Matlab = CreateObject("matlab.application")
MsgBox("In MATLAB, type" & vbCrLf _
    & "str='new string';")

Open the MATLAB window, then type:
```
str='new string';
```

Click Ok.

Try
    S = Matlab.GetCharArray("str", "base")
    MsgBox("str = " & S)
Catch ex As Exception
    MsgBox("You did not set 'str' in MATLAB")
End Try

The Visual Basic MsgBox displays what you typed in MATLAB.
