Re: Report Designer - How to access a CrossBandLine from script (error BC30451)

Hi Alex,

It looks like cross-band lines may not be available to scripts. Most objects exist within a band, but by definition, cross-band lines do not. I believe this poses a problem for Report Designer being able to reference them within a script. You’ll notice that you are also unable to apply a script directly on a cross-band line object.

You may be able to accomplish this using conditional formatting instead by applying a formatting rule to your cross-band line. Your other option would be to use multiple standard line objects instead.

I hope this helps.

Hi,

In my report, I put a OnBeforePrint script in one "Detail" band, under this "Detail" band, there are some crossbandline, one crossbandline is named as "cbvl5"

Here are code segment:

Private Sub OnBeforePrint(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintEventArgs)

Dim bPrintContainerNoAndDepot as Boolean
bPrintContainerNoAndDepot = False

[skip some codes]

if (bPrintContainerNoAndDepot = True) then
lblContainerNo.Visible = True
lblDepot.Visible = True
fldContainerNo.Visible = True
fldDepot.Visible = True

''Item size
else
lblContainerNo.Visible = false
lblDepot.Visible = false
fldContainerNo.Visible = False
fldDepot.Visible = False
cbvl5.Visible = False

[skip some codes]

while previewing this template, I got this error message:

Detail.OnBeforePrint, line 27: error BC30451: Name: "cbvl5" is not declared.

it seems that the program can not find "cbvl5". (but for other UI items like label, it is no problem to access them.)

Hi Alex,

Have you had a look at the XRCrossBandLine documentation? Would you consider posting your script? It’s difficult for me to determine the cause of the issue without seeing what you’re doing.

Report Designer - How to access a CrossBandLine from script (error BC30451)

Hi,

In report designer, I try to access a crossbandline in script. However, I always get error like:

Detail.OnBeforePrint, Line 27: error BC30451: Name "cvbl5" is not declared.

"cvbl5" is name of my crossbandline. I can access label in the script without any problem, so the question is, how can I access crossbandline in script? Thanks.

Alex
