MsFlexGrid to Array

Posted on 2004-04-07
Last Modified: 2008-01-09
hello experts,
this is a tough one to explain, and may prove a bit tricky, but bear with me.

I have a MsFlexGrid(msData) which I have been able to add a check box to using the following code (see below).
This allows me to multi-select without using ctrl click.

here's the problem;
1.  for each row that is selected, I need to be able to store the value of the 3rd column of the selected row in a variable array.

something like this:

Private Sub MsData_Click()
  Dim LastNames As String
  LastNames = MsData.TextMatrix(MsData.Row, 3)
end sub

the above code does NOT work, but essentially, I want to assign the value as above.

2. when the user deselects the checkbox, the value has to be removed from the array

3. I will then need to use the values in the array in the following SQL statement:
              select * from Table1 where Table1.Field1 = "  & LastNames & "
               so I will need a loop. (Is this possible and if so how do I do it.)

here's the code I used to add the checkbox (COURTESY OF: mgfranz @ ;

For i = 1 To objRec.RecordCount     'objrec is my recordset
     With MsData
          .Row = i: .Col = 0: .CellPictureAlignment = 4 ' Align the checkbox
          Set .CellPicture = picUnchecked.Picture  ' Set the default checkbox picture to the empty box
          .TextMatrix(i, 1) = i
     End With

then the following code is used by the original coder for select and deselect events:
(I have modified it slightly)

Private Sub MsData_Click()
Dim i As Integer
Dim oldx, oldy, cell2text As String, strTextCheck As String

  'this will highlight the current row
   MsData.HighLight = flexHighlightAlways
   MsData.SelectionMode = flexSelectionByRow
   MsData.Col = 0
   MsData.ColSel = MsData.cols - 1
' Check or uncheck the grid checkbox
With MsData
    oldx = .Col
    oldy = .Row
        If .Col = 0 Then
            If .CellPicture = picChecked Then
                Set .CellPicture = picUnchecked
                .Col = .Col + 1  ' I use data that is in column #1, usually an Index or ID #
                strTextCheck = .Text
                ' When you de-select a CheckBox, we need to strip out the #
                strChecked = Replace(strChecked, strTextCheck & ",", "")
                ' Don't forget to strip off the trailing , before passing the string
                Debug.Print strChecked
                Set .CellPicture = picChecked
                .Col = .Col + 1
                strTextCheck = MsData.TextMatrix(MsData.Row, 3)
                strChecked = strChecked & strTextCheck & ","
                Debug.Print strChecked
            End If
        End If
    .Col = oldx
    .Row = oldy
End With
 'For i = 0 To 2
     LastNames = MsData.TextMatrix(MsData.Row, 3)
  'Next i
 Combo1.AddItem LastNames
End Sub

Please help, crucial project!!

First of all the URL you gave cannot be viewed. It gives an error.

Why don't you just put a button under the grid and user can hit the button when all selections end. When the button clicked you can do something like that:

Private Sub cmdSelectNames_Click()
Dim i as integer
dim lastnames,strSQL as string
with MsData
for i=0 to .Rows-1
if .cellpicture=picChecked then
lastnames=lastnames & "'" & .TextMatrix(i,3) & "',"
end if
next i
end with
lastnames=left(lastnames,len(lastnames)-1) ' To remove the last comma
strSQL="select * from Table1 where Table1.Field1 in (" & lastnames & ")"
End Sub

This should work...

hi CaN,
sorry about that, here's the URL again.

a little more help please....(my vb/access is not that great..)
would your code not give the values in the variable LastName as:
name1, name2, name3, name4....
I tried this in access and it gives me a syntax error in access.

thank you...

it shouldn't give an error
LastName becomes a string as


and SQL becomes a string as

select * from Table1 where Table1.Field1 in ('name1','name2','name3','name4')

I checked again and it works in Access
