The following sentences:

Const cnCharWidth = 190 'A Chinese character is 190 twip wide
Const cnCharHeight = 240 'A Chinese character is 240 twip high

dim ctl as control

Set ctl = CreateReportControl(rpt.Name, acTextBox, acPageFooter, , , 0, 50, cnCharWidth * 10, cnCharHeight)

Can run in my notebook and PC very well. However, when I transfer them to another PC, System says I can't set properties to the control; after I changed acTextBox to acLabel, it also can work. What is the problem with these sentences?
