Does anyone know why a Page_Load would be called twice on a page when requesting an aspx page?I am using .Net 2.0 with the new .net 1.1 compilation model installed. Whenever I request a page, the Page_Load on the aspx page appears to be called twice, so does the Page_Load on and user controls added to that page.

In an .aspx page with a VB.NET codebehind I am using an IFRAME which would be created inside the repeater control. Since I want to resize the IFRAME based on the content within the page I have been using the resize function obtained from here on the IFRAME onload as shown below.
<iframe id="IframeSubsectionArea" scrolling="auto" width="100%" onload="resizeIframeToFitContent(this)" runat="server">
However it is throwing an error as the method could not be found in the form. Is there any client side script variant for the onload event?

I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

I have an aspx page with three web controls: one to control the List Users page, one to control the Edit Users page, and one to control the Add User page. I have discovered a method for accessing these elements, but it seems to be limited. Here is what I have done:
Protected Sub editUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs)
'set selected user from gridview.
[Code].....
This works in most cases. However, I am unable to access the "enabled" attribute of these web controls. Why is this, and how might I access that attribute?

I am trying to check all the checkboxes on a webform (aspx) page, which is inside a master page,depending on the ID of the checkbox. The checkboxes are created dynamically, so I only know the prefix for finding it. So, I need to find these checkboxes by iterating the controls on the page somehow. It's not working out.

I have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.
I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.

I suspect I am being very silly here but I have the following setup
Class MustInherit myBaseClass
'some stuff
End Class
Class myInheritedClassA
[code]....
Running this results in the following error
Unhandled Exception: System.InvalidOperationException:
There was an error generating the XML document. --->
System.InvalidOperationException:
[code]....
is there any way of 'Widening' the inherited class to the base class so this would work?
EDIT:regarding XmlInclude(typeof inheritedClass), currently this method could potentially return a number of types of inherited class (i.e myInheritedClassA and myInheritedClassB) is it case of simply having to add each of the inheritedTypes in this tag?

I understand that inherited classes can't be converted from base classes. But is there any way to write a conversion sub, so that the base class gets assigned to MyBase, then extra properties are added?[code]...

I'm trying to force an inherited class to use a custom attribute. I'm creating a class library where the user who wants to create an item will do so, but be forced to add an attribute (or visual studio will automatically add the default attribute) to their inherited class. Here is what I'm hoping to achieve:
BaseClass.vb:
<CustomAttribute(10)> _
Public Class BaseClass
End Class
MyClass.vb:

bare with me during this silly example. :-) Let's say I have a class like this:
Public Class Animal
Public iLegs as int32 ' Number of legs
Public bWings as Boolean ' Wings? Yes/No
End Class
And another class that inherits the "Animal" class and adds one more property:
Public Class ScaryAnimal
Inherits Animal
Public iScariness as int32 ' 0-100, how scary is it?
End Class
Now, if I have an instance of "Animal" with some values in it, and I decide I want to cast it to a ScaryAnimal for some reason, how do I do that without having to create a new instance of "ScaryAnimal" and copy each property value?Basically I'm looking for a way to do this, without having to write the lines marked with '*** below:

In my web app, I have an aspx page which contains an html table and several lines of text. I need users to be able to download this whole page as a separate file.
In the past I have used the a webclient to do this:
Dim myWebClient As New System.Net.WebClient
myWebClient.DownloadFile(strSource, strDest)
Response.AddHeader("Content-Disposition", "attachment;filename=test.doc")
Response.Write("test.doc")
but it appears this is only able to download html pages.

I have 3 vb classes and I am trying to add them to my aspx vb page. I try to do
Dim Class1 as new class1 but only one of them works, the other 2 do not work. I made a sample class and put the following in it:
Public Class test
Public Sub test (byref test as string)
test = 5
end sub
End Class
Then I went and tried to do Dim test as new test but it doesn't work, what am I doing wrong? The other class works fine and I don't know why this one wouldn't.

The program below trhows an error in the line "mTable2 = mTable.Copy". The error is: "Unable to cast object of type 'System.Data.DataTable' to type InherintanceQuestion.InheritedTable". This is because mTables is an instance of the InheritedTable class which inherits a DataTable and mTable is a DataTable. So, is there any way I can create the mTable2 to the mTable.copy to the mTable.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
