Hi all, 

Several years ago I asked how to run a program from my app and wait for it to finish before continuing.  It was suggested that I use an object called n_runandwait developed by Roland Smith.  That worked like a charm! Now I'm compiling 64-bit applications, and it does not work with the 64-bit version of my application. Does anyone know what to do? Here's a snippet of the code:

		n_runandwait lnv_RunAndWait
		for li_x = 1 to li_SelectedCount 
...Do Stuff...
				ls_file = "C:\Cal Labels\CalLabels.exe " + string(ll_WorkOrder)
				lnv_RunAndWait.RunAndWait(ls_file, 1)
         next

For now, I just use the RUN(file name) command. It's not a problem, but the user might end up with 10 or more instances of the other program open all at once.

Hoping Roland might see this message and maybe have a new release of n_runandwait object. I'm using PB2022 R3, MR 3397.
