The ListView Windows control has some additional features that haven’t been exposed in the OCX provided with VB. One feature can shrink or enlarge columns automatically to ensure that data in each column is visible and that no screen space is wasted. Use this function to make an API call:
Public Declare Function SendMessage Lib "user32" Alias _ "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As _ Long, ByVal wParam As Long, lParam As Any) As LongConst LVM_SETCOLUMNWIDTH = &H1000 + 30Const LVSCW_AUTOSIZE = -1Const LVSCW_AUTOSIZE_USEHEADER = -2Sub AdjustColumnWidth(LV As ListView, AccountForHeaders _ As Boolean) Dim col As Integer, lParam As Long If AccountForHeaders Then lParam = LVSCW_AUTOSIZE_USEHEADER Else lParam = LVSCW_AUTOSIZE End If ' Send the message to all the columns For col = 0 To LV.ColumnHeaders.Count - 1 SendMessage LV.hwnd, LVM_SETCOLUMNWIDTH, col, ByVal lParam NextEnd SubYou can resize all columns, taking the text in column headers into account by passing True as the second argument:
AdjustColumnWidth ListView1, TrueIf you pass False as the second argument, the text in column headers is ignored in determining the correct width.
