I have code that changes the bkground color of the webform on page_load.
Here it is:
Dim Body As New HtmlGenericControl
Body = CType(Page.Controls(1), HtmlGenericControl)
Body.Attributes("bgcolor") =
ConfigurationSettings.AppSettings("BackgroundColor")
I'm getting this error message "System.InvalidCastException: Specified cast
is not valid." at this line:
Body = CType(Page.Controls(1), HtmlGenericControl)

Hi!
I keep getting this error, but I'm not sure why. When I turn off the trace
flag, I only get it at certain times. Even with the trace flag set to true,
I don't understand the output diagnostics. It shows a list of the controls
on the page (or is this a partial list?) and I don't see where it has found
multiple controls with IDs of '_ctl24'. Here is my list of controls. Any
help or suggestions are MUCH appreciated!
Thanks!

I have a routine that is called on Page_Init. It retrieves folder records
from a database which I display as Link Buttons in a table cell. I set the
table cell's bgcolor to a default color (say black for example). I am
dynamically creating the LinkButton controls and adding them into the table
cell and I've also hooked up an event handler for each LinkButton's Click
event. This all works fine.
Now in the Link Button's Click event...

Hi,
I encountered a strange problem while working on an application, the
problem goes like this. I am generating
a few textboxes at runtime at the server side and added to a
placeholder, a value is set for each of the textboxes.
There is a button that causes the page to be posted back and the
texboxes are re-rendered. When the textboxes are re-rendered the values
are
reset and these texboxes are again added to the placeholder. The names

which will output quite a lot of HTML to the client. The question now
is whether to use the built-in HtmlControls:
HtmlTable tab = new HtmlTable();
this.placeHolder.Controls.Add(tab);
or to manually output the HTML using this kind of syntax:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
