    VB .NET Picturebox events... frustrating :(

    Hi Guys,

    I am trying to add some event handlers to my picturebox object which I am creating at runtime. The compiler (Visual Studio 2005) is flagging the code and telling me that the object does not have the events I am using. The code works fine for labels, just not for this picture box. Where have I gone wrong? :(

    Here is my code:

    Code:
    Dim ctrl_pb = New PictureBox
ctrl_pb.Location = New Point(5,5)

        VB .NET Panels, Controls and Mouseover Events - Advice welcome

        Dear All,

        My question refers to how best to organise my mouse events to correctly and efficiently give the effect I want.

        On my form I have a panel and that panel contains a number of controls.

        By setting up the MouseOver and MouseOut events for the panel I am able to change the panel's background while the mouse is over the panel. A very simple effect and one that is straightforward to implement.

          Brilliant!!! The .Clear() method works perfectly.

          In general though, I didn't realise the limitations of "For Eaching" through an ArrayList.

          What if I had a general ArrayList and wanted to remove some elements from it (those that match some criteria) by "For Eaching" through the list. Then by disposing those members that I do not want will I not have the same problem?

          What is the correct...

            VB .NET Strange Behaviour When Removing Form Controls

            Hi guys,

            I have a panel on a form and at runtime I create some controls on the panel. Then, also during runtime I want to clear the panel of all of its controls. The basic way to do this is with the following code:

            Code:
            For Each this_ctrl As Object In target_panel.Controls
     this_ctrl.Dispose()
Next
            What happens when I use this code is that only every second control is removed from the panel!...
