Converting Attachmate X-tra to Reflection 14 within Powerbuilder 10.5 (getstring?)

Posted on 2009-05-18
Last Modified: 2013-12-20
I am trying to convert my Powerbuilder application from using OLE Attachmate Extra to Reflection 14.  I noticed that I cannot use the same script that I've used before.  I've found equivalent functions that can replace my other functions.  Unfortunately, I can't find anything to replace the GETSTRING().  IF lole_session.GetString(1,73,4) <> "FMSP" does not work.  Can anyone assist? I've attached a brief code snipet below.
I get "Error calling external object function getstring" on the getstring() calls.
lole_session = CREATE uos_oleobject
IF lole_session.ConnectToObject(lstr_fms_fname) <> 0 THEN
	fpub_got_error("COW0190059", "fpvt_access_fms", "")
	return -1
IF NOT lole_session.IsAlive() THEN
//IF NOT lole_session.Visible THEN
   // FMS session does not exist. Show message to the user that they need to login	
	fpub_got_error("COW0190053", "fpvt_access_fms", "")
	lole_session.Visible = TRUE
	Return -1
//lole_screen =  lole_session.GetActiveSession()
//lole_screen = fpub_uos_oleobject(lole_session.Screen)
//Make sure user is on a valid menu
IF lole_session.GetString(1,73,4) <> "FMSP" AND &
	lole_session.GetString(1,25,12) <> "NVi/TPX MENU" AND &
	lole_session.GetString(1,26,22) <> "DMS/VS SECURITY SYSTEM" THEN
	// Show message to the user that they need to login
   fpub_got_error("COW0190060", "fpvt_access_fms", "")
   Return -1
//Get to the main menu if not there
//IF lole_screen.GetString(1, 25, 12) <> "NVi/TPX MENU" THEN
IF lole_session.GetString(1, 25, 12) <> "NVi/TPX MENU" THEN
	lole_session.TransmitANSI( "cssf logoff")
//	lole_screen.SendKeys("<Clear>")
//	lole_screen.SendKeys("cssf logoff<Enter>")

I think getstring is trying to read data from excel. You must need to find similar function or approach in reflection. Without that it will not work because GetString is perticular OLE function not the PB function.

Thank you for the response.  I am trying to access an IBM 3270 reflection session from within a powerbuilder oleobject.  The code worked for an Attachmate Extra session.  I am trying to convert the code to access an attachment reflection 14 session.  I could not find any really good documentation on the topic of reading the screen with reflection 14.  

I believe you are right.  The getstring is not valid for the reflection session.  I am looking for an equivalent function.

You should be able to see all the functions, events and properties of Reflection OLE under PB's object browser > OLE Tab

Check if you see something similar there....

Thank you for your help.  I found the function that I was looking for GetDisplayText(Reflection) can be used in place of GetString(Extra).
.GetDisplayText(1, 1, .DisplayColumns * .DisplayRows)
