Hi all,

I need to loop through a few records and if all conditions are met, run a program.  This works fine for one record.  The program I'm running requires user interaction.  Is there a way to wait for the other program to close before moving to the next record?  The other program is a C# program that prints a label.  The user has to click Print to actually print the label, in case they want to change the print template or printer.  So it could take 10 seconds, or 2 minutes.  

My loop is working fine, but it launches the label program, then moves on to the next record. And launches the label program again.  So I end up with 4 or 5 (possibly more) instances of the label program running.  I put a 10 second delay in, which gives time for the program to launch and the user to click Print.  But not much more time for anything else.

		for li_x = 1 to li_SelectedCount 
			ll_WorkOrder = this.GetItemNumber(ll_SelectedRows[li_x], "workorder")
			ls_finished = this.GetItemString(ll_SelectedRows[li_x], "certificate_done")
			if IsNull(ls_finished) then
				MessageBox("Print Label","Certificate is not started for WO# " + string(ll_WorkOrder))
			elseif ls_finished = 'F' then
				MessageBox("Print Label","Certificate not finished for WO# " + string(ll_WorkOrder))
			else
				Run(ls_file + " "  + string(ll_WorkOrder))
				//Add a pause
				StartTime = Now()
				DO
				LOOP Until SecondsAfter(StartTime,Now()) > 10
			end if
		next

 

Thanks,

~~~Tracy
