[RESOLVED] Excel gets locked when executing a macro

Hi Guys,

I am running a macro to extract data from a mainframe terminal emulator through a VBA macro in excel.

The macro works fine and gives me the desired output. But after I execute the script, if I navigate to see the mainframe terminal am not able to view the excel sheet until the macro gets completed.

Is there a any specific option that i can use to keep the excel sheet viewable when the macro is in execution?

Please help!

In most cases I'd try the other way around (i.e. not update the worksheet while the macro is running).
Did you use the "application.screenupdating=False"?

you can use doevents to help with this (yields to other processes), with in any loop

avoid using selection, select, activate or active anything within your code, as these all slow down the processing and increase possibility of errors ocurring

show your macro

@opus - I am not using "application.screenupdating=False"!

@westconn1 - could you please brief me more on the "doevents"?

@kaliman79912 - here is the sample code that am using:

"Private app As PASSOBJLib.System
Private session As PASSOBJLib.session
Private screen As PASSOBJLib.screen
Private Wkbook As excel.Workbook
Private Wksht As excel.Worksheet

Dim Var As String

Sub Mainframe_Connect()

Set app = New PASSOBJLib.System

Set session = app.ActiveSession

Set screen = session.screen

For i = 1 To 20

screen.SendKeys ("<Home>")
screen.SendKeys ("3.4")
screen.SendKeys ("<Enter>")
screen.SendKeys ("<PF3>")

Next

End Sub"

vb Code:

For i = 1 To 20
 
screen.SendKeys ("<Home>")
screen.SendKeys ("3.4")
screen.SendKeys ("<Enter>")
screen.SendKeys ("<PF3>")
doevents
Next

i doubt that preventing screenupdating will help you or be desirable in this case

@westconn1 - Thanks a ton! Works cool...lil slow though which is understandable...

Thanks again!

what do you have in <PF3>? You might be able to do what you want without sending keys, which has very bad performance.

<PF3> is a keystroke action which i need to perform in the mainframe screen.
(ie.,) i need to press the F3 key which is defined as PF3 in the mainframe emulator..

Thoughts?
