Issues with ListBox

[ksps1024]

Hi,

I'm having issues with the listbox control. I have created a custom page with a listbox, and am populating it with strings read from a file(>1000 lines). The problem I'm experiencing is that while the items are being inserted into the listbox, I do not see them there until the process completes. Now the interesting part is that I can see the vertical scrollbar shrink. Once the file read is complete, then it displays the items in the listbox.....

Below is excerpt for the insertion of the strings.

code:




${NSD_CreateListBox} 0 25 100% 80% " "

pop $listbox



SendMessage $listbox ${LB_INSERTSTRING} -1 "STRelete: $R0"

Any ideas how to get around this?

I'm trying to accomplish something similar to the install part where you can see the details of the installation.

Thanks in advance....
