Hello , i have a database for mine magazines. All are oK. Recently i shaw an isuue that i did't shee before.
I have some buttons to navigate the first , last , next , previous records . I shaw when i press the last button , it goes to the last record and it's OK. When from this position i press the previous button , also goes to the previous . But when i am in the last record and i press the first button , to go to the first record the screen become empty and seems like freesing without displaying anything. In debug mode and in logs , there is nothing message. The code is as follows :



Sub LoadRecords

' Dim t As Long
Curs.Position =RecIndex

lblAmID2.Text = Curs.GetString2(0)
lblAmPCode2.Text = Curs.GetString2(1)
lblAmAch2.Text = Curs.GetString2(2)
lblAmMY2.Text = Curs.GetString2(3)
lblPage2.Text = Curs.GetString2(4)
lblTitle2.Text = Curs.GetString2(5)
lblCategory2.Text = Curs.GetString2(6)
lblSpeaker2.Text = Curs.GetString2(7)
lblOrigin2.Text = Curs.GetString2(8)
lblSuccLevel2.Text = Curs.GetString2(9)
lblSuccMY2.Text = Curs.GetString2(10)
lblPhotoYN2.Text = Curs.GetString2(11)
lblTefxos2.Text = Curs.GetString2(12)
lblPinPhoto2.Text = Curs.GetString2(13)
lblPdfFile2.Text = Curs.GetString2(14)
lblExofyllo2.Text = Curs.GetString2(15)


RecIndex1 = RecIndex + 1
Activity.Title= "Record/s : " & RecIndex1 & " From : " & RecNum



End Sub

Sub btnFirst_Click
RecIndex=0
Msgbox("This is the 1st record", "ATTENTION!")
Activity.RemoveAllViews
LoadRecords
End Sub


Sub btnPrev_Click

RecIndex = Max(RecIndex - 1, 0)

LoadRecords

End Sub


Sub btnNext_Click

RecIndex = Min(RecIndex + 1, Curs.RowCount - 1)

LoadRecords
End Sub


Sub btnLast_click

RecIndex = Curs.RowCount - 1
Msgbox("Thi sis the last record ", "ATTENTION!")

LoadRecords
End Sub


Any idea , what is wrong ?

you remove everything with this

Sub btnFirst_Click
RecIndex=0
Msgbox("This is the 1st record", "ATTENTION!")
Activity.RemoveAllViews   <- !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
LoadRecords
End Sub

Do you suggest to add Activity.RemoveAllViews to the next , last and previous click events ?

Sorex is telling you to get rid of the line: Activity.RemoveAllViews or comment it, not add it to any.
By the way, you should really use code tags when you display a lot of code, because you have been a member for 3 years.

right, you remove everything visible in your app that's why you end up with an empty screen.

remove it or modify it to the panel you want to clear.
