Crystal Reports 中的“无效对象格式名称”

Question

When working with Crystal Report Field Objects and attempting to set "EnableSuppress" to False or alter the position or width of a field object is generating an "Invalid Object Format Name" error. The debugger shows all my code running without error until attempting to actually load the report. At that point, it will run the first couple without problem, then it fails when messing with a field object, and none of the rest will run. The code is shown below. Everything that generates an error is a FieldObject, but not all fieldObjects generate errors. In the code below, everything in Section2 is a TextObject and everything in Section3 is a FieldObject.

If condition = True Then
'Lines marked as runs ok, only run when a line that generates an error is not present before it.  
    Report.Section2.ReportObjects("Text7").Left = 7830      'Runs ok  
    Report.Section3.ReportObjects("Field4").Left = 8085     'Runs ok  
    Report.Section2.ReportObjects("Text13").ObjectFormat.EnableSuppress = False    'Runs ok  
    Report.Section3.ReportObjects("Field28").ObjectFormat.EnableSuppress = False   'error  
    Report.Section2.ReportObjects("Text9").Left = 10830     'Runs ok  
    Report.Section3.ReportObjects("Field23").Left = 10830   'error  
    Report.Section3.ReportObjects("Field23").Width = 615    'error  
    Report.Section2.ReportObjects("Text10").Left = 11445    'Runs ok  
    Report.Section3.ReportObjects("Field25").Left = 11445   'Runs ok  
End If

Answer 1

Unless you figure out what is different about the fields that throw errors and are absolutely set on formatting in VB code, I suggest that you do your formatting from within the Crystal report. You obviously know about the conditional suppression and to change size and location of a field you can right-clicking on the field and clicking "Size and Position". There is also an option for conditional placement (formula).

Hope that helps,
