OLE Automation Example

Here’s a new example, which is using OLE Automation only (there’s no form with an OLE object on it).  This is an example of accessing data in another (ODBC) database:

% ADO (ActiveX Data Objects) Sample

PROCEDURE pAdoTest() Local(firstName)

  Let cn = $ObjCreate("ADODB.Connection")

  Let rs = $ObjCreate("ADODB.RecordSet")

  out 'Connecting to the database...'

  let v1=$objsetproperty(cn,"ConnectionString","DSN=AccessCustomers")

  let v1=$objsetproperty(cn,"CursorLocation",3)  % adUseClient

  let v1=$objrunmethod(cn,"Open")

  out 'Preparing RecordSet...'

  let v1=$objsetproperty(rs,"Source","Select * from Customers")

  let v1=$objsetproperty(rs,"ActiveConnection",cn)

  out 'Opening the recordset...'

  let v1=$objrunmethod(rs,"Open")

  out 'Returned records:'

  while $objgetproperty(rs, 'EOF') = 0

     Out $ttrim($objgetproperty(rs, 'Fields', 'FirstName'))

     Let vResult = $ObjRunMethod(rs, 'MoveNext')

  endwhile

  Let cn = $Null  

  Let rs = $Null

ENDPROCEDURE

Word Example

Example Name : ActiveX Word Sample

Control Used : Microsoft Word

Zim Program Source Code

procedure pAXWord()  

win open waxword at center for faxword

form open faxword

form display

win activate

while

  form input

  case

  when event.fieldtag = "Cancel_Button" or event.eventname="Closed"

  win close

  return

when event.fieldtag = "OK_Button" and faxword.text_word is not $null

%start up Word

let vWordApp  = $ObjCreate('Word.Application')

let vWordDocs = $ObjGetProperty (vWordApp, 'Documents')

let vWordDoc  = $objRunMethod (vWordDocs, 'Add')

%make Word visible

let vResult = $objsetproperty(vWordApp, 'Visible' ,1)

% Select Range

  let vWordRange = $objRunMethod(vWordDoc, 'Range', '0', '0')

  %give it some data

  let vresult = $objRunMethod (vWordRange, 'InsertAfter', faxword.text_word)

%destroy the object

let vresult   = $null

let vWordDocs = $null

let vWordDoc  = $null

  %close Word Application

  let vResult = $objRunMethod (vWordApp, 'Quit')

let vResult   = $null

let vWordApp  = $null

  otherwise

  form set focus faxword.text_word

  endcase
