thanks a lot, tobias, danke sehr, genau was ich brauche - just what I was looking for and searched a lot for. and an extra thanks for the very detailled description; mostly there is one little point, clear to anyone who uses this every day, and therefor not mentioned, but an obstacle to the newbie.
now I am looking forward to use this new knowledge in my software. regards, Dag-Jarle Johansen 2011/8/28 tobias <tobiasb...@web.de> > hi, > > > I do not check this at all: > > > > Public Sub Page_First_Init() > > Dim hPictureBox As PictureBox > > Dim I As Integer > > For i = 0 To 9 > > hPictureBox = New PictureBox(Me) As "PBX" > > hPictureBox.Tag = i > > Next > > End > > ok, you have a loop from 0 to 9 in which you create PictureBoxes by > using New, each of them gets the event name "PBX" and a tag to identify > them. > those PictureBoxes are created on Me and therefore now normal controls. > you additionally hold a reference to the just created one in hPictureBox > so you can change its attributes as you want: > hPictureBox.Visible = False > you can pick a particular box using Me.Children (i don't know, if this > is the best solution for it): > > Public Function Pick(iInd As Integer) As PictureBox > Dim cControl As Control > > For Each cControl In Me.Children > If Object.Type(cControl) = "PictureBox" And cControl.Tag = iInd Then > Return cControl > Endif > Next > Return Null > End > > the thing with this is that Tags may be set arbitrarily, so checking if > the control is also a PictureBox is a little more secure not to give > something wrong back but keep in mind that for some reason, you may have > given another PictureBox the same Tag which leads to giving back the > first one recognized in Me.Children...
