[RESOLVED] MSFlexGrid Row Anomalys

Anyone had any when updating a msflexgrid (which includes clearing then re-populating).

I keep having rows pop out of nowhere, and when I click on my re-populate query, they subquentially go from one less row to the correct number...

In general I'm having all sorts of bugs, prob which are attributed to my code,

Currently here is my main code that writes to the flexgrid.

VB Code:

Private Function WriteShow(pShow As String)
    Debug.Print "Writing Show"
    On Error GoTo Error
    
    If Selection = Show_Name Then
        'TreeView.SelectedItem.Next
        'TreeView.SelectedItem.Next
        'TreeView.SelectedItem.Next
        Selection = Show_Name & ".Rundown"
    End If
    
    FlexGridDone = False
    
    
    
    
    Dim Counter As Integer
    Dim Counter2 As Integer 'For Refresing of FlexGrid
    Dim Total As Integer
    'Remove All Items Cept The First Top Item!
    
    Counter2 = 2
    
    Total = MSFlexGrid1.Rows
    
    'Remove all items?
    If Total >= 1 Then
        Do Until Counter2 = MSFlexGrid1.Rows
            MSFlexGrid1.RemoveItem (Counter2)
            Counter2 = Counter2 + 1
        Loop
    End If
    
    'Act Normal
    cn.Open
    SQL = "SELECT * FROM `Rundown` WHERE `Show` = '" & Show_Name & "' ORDER BY `Pos` ASC"
    
    rs.Open SQL, cn, adOpenForwardOnly, adLockOptimistic
    Counter2 = 0
    
    'MSFlexGrid1.RemoveItem
    Counter = 1
    With rs
        Do Until rs.EOF = True
            MSFlexGrid1.AddItem ("")
            'Fill In the Col. Data.
                MSFlexGrid1.TextMatrix(Counter, 2) = !Tal
                MSFlexGrid1.TextMatrix(Counter, 3) = !Slug
                MSFlexGrid1.TextMatrix(Counter, 4) = !Format
                MSFlexGrid1.TextMatrix(Counter, 5) = !Graphics
                MSFlexGrid1.TextMatrix(Counter, 6) = !Status
                MSFlexGrid1.TextMatrix(Counter, 7) = !Tape
                MSFlexGrid1.TextMatrix(Counter, 8) = !SOT
                MSFlexGrid1.TextMatrix(Counter, 9) = !Read
                MSFlexGrid1.TextMatrix(Counter, 13) = !autonumber
                '.TextMatrix(Counter, 2) =
            'Go To New Row
            'Fill First Col With Data
            Counter = Counter + 1
            .MoveNext
        Loop
        
    End With
    
    
    Dim Total_Results As Integer
    Total_Results = Counter - 1
    rs.Close
    cn.Close
    
    
    'Fix for wierd cell bug
    MSFlexGrid1.Row = 1
    MSFlexGrid1.Col = 1
    MSFlexGrid1.CellBackColor = RGB(255, 255, 255)
    
    
    'Possibly Fix another bad FlexGrid Bug?
    If MSFlexGrid1.Rows >= Total_Results Then
        MSFlexGrid1.RemoveItem (MSFlexGrid1.Rows)
    End If
    
    If Not MSFlexGrid1.Rows = Total_Results Then
        WriteShow (Show_Name)
        MSFlexGrid1.Redraw = True
        MSFlexGrid1.Refresh
    End If
    
    'Fix another flexgrid bug we've developed!
    'Remove all rows w/o Identifer
    'Dim Counter3 As Integer
    'Counter3 = 2
    'Do Until Counter3 = MSFlexGrid1.Cols
    '    If MSFlexGrid1.TextMatrix(Counter3, 13) = "" Then
    ''        MSFlexGrid1.RemoveItem (MSFlexGrid1.Row)
     '   End If
    ' '   Counter3 = Counter3 + 1
    'Loop
    
    FlexGridDone = True
    FillGrid = True
    MSFlexGrid1.Redraw = True
    MSFlexGrid1.Refresh
    
Error:
    If Err.Number = 30002 Then
        MSFlexGrid1.Redraw = True
        MSFlexGrid1.Refresh
        FlexGridDone = True
        FillGrid = True
    End If
        MSFlexGrid1.Redraw = True
        MSFlexGrid1.Refresh
        FlexGridDone = True
        FillGrid = True
        'Debug.Print "Another FlexGrid Error " & Err.Number & " " & Err.Description
End Function

Sorry I know it's crappy. It would be more suitable to zip up the code and ship it off for help. However I'm referencing a database and it may not show just correctly. However I may let someone here on these forums to VNC in if they would like... that's a worst case senario though... HOpefully someone can find something in this block of code and help me understand why my code doesn't work... I know it must be my code and not FlexGrid!

Could this:

Total = MSFlexGrid1.Rows

'Remove all items?
If Total >= 1 Then
Do Until Counter2 = MSFlexGrid1.Rows
MSFlexGrid1.RemoveItem (Counter2)
Counter2 = Counter2 + 1
Loop
End If

be the problem?

I would use:
Total = MSFlexGrid1.Rows

'Remove all items?
For x = Total to 1 Step -1
MSFlexGrid1.RemoveItem (x)
Next x

Your Code prevents any of my rows from showing (except the required first one, which shows up blank; which is wrong), that code I'm using only shows 1/2 of them

Sorry, I thought from the commented line that you wanted to remove all of the existing rows from the grid before repopulating it. I'm sorry, I didn't read all of your code, and that just jumped out.

that's what I want to do though.

I was patching the code as you see later to remove false lines where there was no data populated back from the sql server.

This function is to remove all code, then repopulate it. I have a treeview next to the code that is called, it strings to the writeshow function the show that needs to be populated. That is why you see a SQL query inside the code.

Is it your aim to remove all the data from the grid? If so then just use MSFlexGrid1.Clear

Eureka! Why haven't I seen that before! Now the code Infitely loops and crashes.

[Removed Stupid Function]

I find thinking too much outside the box, and creating my own way to remove items when a function exists exhausing... Must stop that!

Resolved somewhat... here is the current function... I needed to remove the infite loop that causes it to restart the function...

VB Code:

Private Function WriteShow(pShow As String)
    Debug.Print "Writing Show"
    On Error GoTo Error
    
    If Selection = Show_Name Then
        Selection = Show_Name & ".Rundown"

    FlexGridDone = False
    
    
    
    
    Dim Counter As Integer
    Dim Counter2 As Integer 'For Refresing of FlexGrid
    Dim Total As Integer
   
    
    Counter2 = 2
    
    Total = MSFlexGrid1.Rows
    
    'Remove All Items Cept The First Top Item!
    MSFlexGrid1.Clear
    
    'Act Normal
    cn.Open
    SQL = "SELECT * FROM `Rundown` WHERE `Show` = '" & Show_Name & "' ORDER BY `Pos` ASC"
    
    rs.Open SQL, cn, adOpenForwardOnly, adLockOptimistic
    Counter2 = 0
    
    'MSFlexGrid1.RemoveItem

        Do Until rs.EOF = True
            MSFlexGrid1.AddItem ("")
            'Fill In the Col. Data.
                MSFlexGrid1.TextMatrix(Counter, 2) = !Tal
                MSFlexGrid1.TextMatrix(Counter, 3) = !Slug
                MSFlexGrid1.TextMatrix(Counter, 4) = !Format

                MSFlexGrid1.TextMatrix(Counter, 9) = !Read
                MSFlexGrid1.TextMatrix(Counter, 13) = !autonumber
                '.TextMatrix(Counter, 2) =
            'Go To New Row
            'Fill First Col With Data
            Counter = Counter + 1

        MSFlexGrid1.RemoveItem (MSFlexGrid1.Rows)
    End If
    
    'If Not MSFlexGrid1.Rows = Total_Results Then
    '    WriteShow (Show_Name)
    'End If
        
    FlexGridDone = True
    FillGrid = True
    MSFlexGrid1.Redraw = True

Still getting extra rows from somewhere.

A few comments about your code.

What is the "another bad FlexGrid Bug" you are trying to fix? Note that whatever it is is probably not the flexgrid's fault.

Do you realize that your code "falls through" to your Error: code?

Also do you realize the code in both parts of the If/Else in the Error: code is the same

yes... the code was poorly written at this state, because I was getting no luck with fixing the errors. Like I mentioned in my first post, I seriously doubt that the errors are the controls, and more along the lines of my poor coding. I'm still getting used to the language. I'm barely an intermediate user.

As with some more thinking and looking at the code, I lost my row 0... so the .clear statement won't work... I remember why I did that now. revising the code so I get this back... maybe completely writing that block will clear up some issues.

OK, but what is the "another bad FlexGrid Bug"?

where I remove more items that get inserted somehow... I'm trying to mask the bugs than fix them... Which I'm guessing is not a good idea?

What happens if you change this

VB Code:

Counter = 1
    With rs
        Do Until rs.EOF = True
            MSFlexGrid1.AddItem ("")
            'Fill In the Col. Data.
                MSFlexGrid1.TextMatrix(Counter, 2) = !Tal
                MSFlexGrid1.TextMatrix(Counter, 3) = !Slug
                MSFlexGrid1.TextMatrix(Counter, 4) = !Format
                MSFlexGrid1.TextMatrix(Counter, 5) = !Graphics
                MSFlexGrid1.TextMatrix(Counter, 6) = !Status
                MSFlexGrid1.TextMatrix(Counter, 7) = !Tape
                MSFlexGrid1.TextMatrix(Counter, 8) = !SOT
                MSFlexGrid1.TextMatrix(Counter, 9) = !Read
                MSFlexGrid1.TextMatrix(Counter, 13) = !autonumber
                '.TextMatrix(Counter, 2) =
            'Go To New Row
            'Fill First Col With Data
            Counter = Counter + 1
            .MoveNext
        Loop
        
    End With
    
    
    Dim Total_Results As Integer
    Total_Results = rs.RecordCount
    rs.Close
    cn.Close
    
    
    'Fix for wierd cell bug
    MSFlexGrid1.Row = 1
    MSFlexGrid1.Col = 1
    MSFlexGrid1.CellBackColor = RGB(255, 255, 255)
    
    
    'Possibly Fix another bad FlexGrid Bug?
    If MSFlexGrid1.Rows >= Total_Results + 1 Then
        MSFlexGrid1.RemoveItem (MSFlexGrid1.Rows)
    End If

to this?

VB Code:

Counter = 1
    With rs
        Do Until .EOF
            'Fill In the Col. Data.
                MSFlexGrid1.TextMatrix(Counter, 2) = !Tal
                MSFlexGrid1.TextMatrix(Counter, 3) = !Slug
                MSFlexGrid1.TextMatrix(Counter, 4) = !Format
                MSFlexGrid1.TextMatrix(Counter, 5) = !Graphics
                MSFlexGrid1.TextMatrix(Counter, 6) = !Status
                MSFlexGrid1.TextMatrix(Counter, 7) = !Tape
                MSFlexGrid1.TextMatrix(Counter, 8) = !SOT
                MSFlexGrid1.TextMatrix(Counter, 9) = !Read
                MSFlexGrid1.TextMatrix(Counter, 13) = !autonumber
            Counter = Counter + 1
            .MoveNext
        Loop
        
    End With
    
    
    Dim Total_Results As Integer
    Total_Results = rs.RecordCount
    rs.Close
    cn.Close
    
    
    'Fix for wierd cell bug
    MSFlexGrid1.Row = 1
    MSFlexGrid1.Col = 1
    MSFlexGrid1.CellBackColor = RGB(255, 255, 255)

BTW I think your problem is this line

VB Code:

MSFlexGrid1.AddItem ("")

which doesn't do anything except add blank lines at the end of the grid.

Of Course AddItem will add a blank line, but then I go back in and populate it with textmatrix... thus nulling out the effect of having a blank line. Now why would it add 2 blank lines if it hasn't reached EOF? Anyways, I think I got that part of the code working... I will need to work on some other code not related to this main issue now...

I'm going to toy with the other issue for a while longer because it is not that critical just yet... THus Marking as resolved.

No, that's not what happens. What does happen is that every time that line is executed a new blank line is written, but nothing gets written to those lines. Take a look at this example.
