hi,,

i have this code for viewing a report from my application but when i run the program and click on the report buttin i get this error:
report not found..

the kine colored in red is the one that i get the error in:

Code:

---

Private Sub Command1_Click()


    CrystalReport1.ReportFileName = App.Path & "rent.rpt"
    CrystalReport1.DiscardSavedData = True
    CrystalReport1.RetrieveDataFiles
 

    CrystalReport1.ReportSource = 0
    CrystalReport1.SQLQuery = "select * from rent order by {serial}"
    CrystalReport1.WindowTitle = "Rent system"
    CrystalReport1.Destination = crptToWindow
    CrystalReport1.PrintFileType = crptCrystal
    CrystalReport1.WindowState = crptMaximized
    CrystalReport1.SelectionFormula = "IsNull({Document.rent})"
    CrystalReport1.Action = 1

End Sub

any help please?

App.Path does not include an ending \ (unless the app is in the root directory of a drive). Add a \ to the file name.

CrystalReport1.ReportFileName = App.Path & "\rent.rpt"

i did what you told me and i get this error :
error in formula:( the error is in red)

Code:

---

Private Sub Command1_Click()


    CrystalReport1.ReportFileName = App.Path & "\rent.rpt"
    CrystalReport1.DiscardSavedData = True
    CrystalReport1.RetrieveDataFiles
   

    CrystalReport1.ReportSource = 0
    CrystalReport1.SQLQuery = "select * from rent order by {serial}"
    CrystalReport1.WindowTitle = "Rent system"
    CrystalReport1.Destination = crptToWindow
    CrystalReport1.PrintFileType = crptCrystal
    CrystalReport1.WindowState = crptMaximized
    CrystalReport1.SelectionFormula = "IsNull({Document.rent})"
  CrystalReport1.Action = 1
End Sub

can someone help me please?

What is the code for your formula?

That would appear to be what Crystal doesn't like, but as I don't know what that code is, I can't, at the moment, offer any suggestions.

You specified Document.Rent in the formula. Document is the table name and Rent is the field name. Document is not a table in your Selection formula. Rent is however.

Should the formula be

CrystalReport1.SelectionFormula = "IsNull({Rent.rent})"

or

CrystalReport1.SelectionFormula = "IsNull({Rent.????? Some other field})"
