I need sorting code for my visual basic project. It can be bubble, insertion or selection sort code. I want to be able to sort a field in a grid by surname. I want to also be able to edit entries in the grid as well and save changes, I need amending code for a txt file.

URGENTLY NEED HELP AS MY PROJECT IS DUE NEXT FRIDAY!

Help would be greatly appreciated

I found some code on the net but I haven't tried it out yet.

Bubble Sort Code # 1

Public Sub BubbleSortFlexGrid(FGrid As MSHFlexGrid, _
Col As Long, Optional StartRow As Long = 0, _
Optional Desc As Boolean = False)

Dim SortType As Integer

Dim i As Long

Dim k As Long

Dim Val1

Dim Val2

Dim SecVal1

Dim SecVal2

Dim bSorted As Boolean

Screen.MousePointer = vbHourglass

DoEvents
DoEvents

With FGrid

.Visible = False

DoEvents
DoEvents

.Col = Col
.Row = StartRow

If IsNumeric(.Text) Then

SortType = 1

Else

SortType = 0

End If

Select Case SortType

Case 1

bSorted = False

Do While Not bSorted

bSorted = True

For i = StartRow To .Rows - 2

If Desc Then

.Col = Col

.Row = (i)

Val1 = .Text

.Row = (i + 1)

Val2 = .Text

If csng(Val1) < csng(Val2) Then

DoEvents

bSorted = False

For k = 0 To .Cols - 1

.Col = k

.Row = (i + 1)

SecVal1 = .Text

.Row = (i)

SecVal2 = .Text

.Text = SecVal1

.Row = (i + 1)

.Text = SecVal2

Next k

End If

Else

.Col = Col

.Row = (i + 1)

Val1 = .Text

.Row = (i)

Val2 = .Text

If csng(Val1) < csng(Val2) Then

DoEvents

bSorted = False

For k = 0 To .Cols - 1

.Col = k

.Row = (i)


SecVal1 = .Text

.Row = (i + 1)

SecVal2 = .Text

.Text = SecVal1

.Row = (i)

.Text = SecVal2

Next k

End If

End If

Next i

Loop

Case 0

bSorted = False

Do While Not bSorted

bSorted = True

For i = StartRow To .Rows - 2

If Desc Then

.Col = Col

.Row = (i)

Val1 = .Text

.Row = (i + 1)

Val2 = .Text

If Val1 > Val2 Then

DoEvents

bSorted = False

For k = 0 To .Cols - 1

.Col = k

.Row = (i)

SecVal1 = .Text

.Row = (i + 1)

SecVal2 = .Text

.Text = SecVal1

.Row = (i)

.Text = SecVal2

Next k

End If

Else

.Col = Col

.Row = (i + 1)

Val1 = .Text

.Row = (i)

Val2 = .Text

If Val1 < Val2 Then

DoEvents

bSorted = False

For k = 0 To .Cols - 1

.Col = k

.Row = (i + 1)

SecVal1 = .Text

.Row = (i)

SecVal2 = .Text

.Text = SecVal1

.Row = (i + 1)

.Text = SecVal2

Next k

End If

End If

Next i

Loop

End Select

DoEvents
DoEvents

.Visible = True

End With

DoEvents
DoEvents
DoEvents

Screen.MousePointer = vbDefault


End Sub

BUBBLE SORT CODE # 2


Public Function BubbleSortArray(ByVal NumericArray As Variant) _
As Variant

'RETURNS Array, or vbEmpty if there's an error
'e.g., passed array contains elements that
'can't be compared to each other, such as
'objects

'will work when elements are all numbers or single characters
'of the same case.

Dim lPass as long

vAns = NumericArray

BubbleSortArray = vbEmpty
Exit Function
End If

On Error GoTo ErrorHandler

lStart = LBound(vAns)
lCount = UBound(vAns)
lPass=0

bSorted = False

Do While Not bSorted
bSorted = True

For lCtr = lCount - 1 To lStart + lPass Step -1
If vAns(lCtr + 1) < vAns(lCtr) Then
DoEvents
bSorted = False
vTemp = vAns(lCtr)
vAns(lCtr) = vAns(lCtr + 1)
vAns(lCtr + 1) = vTemp
End If
Next lCtr
lPass = lPass + 1
Loop

BubbleSortArray = vAns
Exit Function

ErrorHandler:
BubbleSortArray = vbEmpty
Exit Function
End Function

One of the things you'll find about programming is that unless you try and write the code yourself, or you actually understand the code you're using, then the chances are the code doesn't actually do exactly what you want it to do.
