flexgrid - image

I like the feature of the grid control that shows a triangle in the first column of the grid when you move the cursor up and down. Is there a way to do that with the hierarchical flexgrid control?
I thougt of puting a triangle image in the first row every time you move up and down - but i dont know how to implement that.

Thanks!

Put Icon in msfg

This code will take the file and the icon and enter to the msfg

OleCreatePictureIndirect is used to create a picture object to display in the flexgrid. But
when I set the CellPicture property to
the picture object, the grid scales the 16x16 icon to 32x32 when displaying it. According to a Google
search, Microsoft acknowledges
this a bug with the flexgrid. They suggest a workaround by enlarging the 16x16 icon to a 32x32 icon.
How would I enlarge the icon to a
32x32 icon without scaling the image nor loosing the transparency information?




Private Sub Command1_Click()

Dim hImgSmall As Long
Dim strFile As String
Dim shinfo As SHFILEINFO
Dim i As Integer

strFile = "C:\myfile.txt"
' Get the small icon data from the file
hImgSmall = SHGetFileInfo(strFile, 0&, shinfo, Len(shinfo), _
SHGFI_SMALLICON Or BASIC_SHGFI_FLAGS Or SHGFI_ICON)

' Populate the grid with the small icon
For i = 1 To MSFlexGrid1.Rows - 1
MSFlexGrid1.Col = 2
MSFlexGrid1.Row = i
MSFlexGrid1.CellPictureAlignment = flexAlignCenterCenter
' Returns the 16x16 icon with all transparency information in tact
Picture1.Picture = IconToPicture(shinfo.hIcon)
Set MSFlexGrid1.CellPicture = Picture1.Picture
Next i

End Sub

Public Function IconToPicture(ByVal hIcon As Long) As IPicture
If hIcon = 0 Then Exit Function
Dim oNewPic As Picture
Dim tPicConv As PictDesc
Dim IGuid As Guid

With tPicConv
.cbSizeofStruct = Len(tPicConv)
.picType = vbPicTypeIcon
.hImage = hIcon
End With

' Fill in magic IPicture GUID {7BF80980-BF32-101A-8BBB-00AA00300CAB}
With IGuid
.Data1 = &H7BF80980
.Data2 = &HBF32
.Data3 = &H101A
.Data4(0) = &H8B
.Data4(1) = &HBB
.Data4(2) = &H0
.Data4(3) = &HAA
.Data4(4) = &H0
.Data4(5) = &H30
.Data4(6) = &HC
.Data4(7) = &HAB
End With

OleCreatePictureIndirect tPicConv, IGuid, True, oNewPic
Set IconToPicture = oNewPic
End Function

Picture in msfg

Sub AddPicToCell(flex As MSFlexGrid, row As Long, col As Long, pic As stdole.StdPicture)
flex.row = row
flex.col = col
Set flex.CellPicture = pic
End Sub

Private Sub Command1_Click()
AddPicToCell MSFlexGrid1, 0, 0, Picture1.Picture
End Sub

Another example of putting picture to msfg

' pictures that we want to enter to the MSFG are on the form (imgItems)
Private Sub Form_Load()
'------------------------
Const NUM_ROWS = 10
Dim i As Integer

flxItems.Rows = NUM_ROWS
flxItems.Cols = 2
flxItems.FixedRows = 0
flxItems.FixedCols = 0
flxItems.GridLines = flexGridNone
flxItems.SelectionMode = flexSelectionByRow
flxItems.RowHeightMin = imgItems(0).Height + _
ScaleY(2, vbPixels, vbTwips)
flxItems.ColWidth(0) = flxItems.RowHeightMin
flxItems.Width = flxItems.ColWidth(0) + flxItems.ColWidth(1) + 400
flxItems.Clear
For i = 1 To NUM_ROWS
flxItems.Row = i - 1
flxItems.Col = 0
Set flxItems.CellPicture = imgItems(CInt(Rnd * 5)).Picture
flxItems.TextMatrix(i - 1, 1) = "Item " & Format$(i - 1)
Next i
End Sub

Do you know how I can clear out the images in all the other cells?

Try
msfg.TextMatrix(Row,Col) = ""

Look at EasyGrid control.
It has everything already.
