'功能:
' 自动调整Grid各列列宽为最合适的宽度
'参数:
' [frmCur].........................................当前工作窗体
' [gridCur]........................................当前要调整的Grid

Dim i, j As Integer
Dim dblWidth As Double

With gridCur
For i = 0 To .Cols - 1
dblWidth = 0
If .ColWidth(i) <> 0 Then
For j = 0 To .Rows - 1
If frmCur.TextWidth(.TextMatrix(j, i)) > dblWidth Then
dblWidth = frmCur.TextWidth(.TextMatrix(j, i))
End If
Next
.ColWidth(i) = dblWidth + dblIncWidth + 100
End If
Next
End With
请问，函数参数的Optional bNullRow As Boolean = True, Optional dblIncWidth As Double = 0是什么意思啊

非常乐意加啊,可是怕人家不愿意啊!
我刚接触编程，就得做个东东，所以问的可能十分基础了！呵呵
十分感谢斑竹！
