IsNumeric(value) should return false if value "can not be
successfully converted to a Double." Instead I get the
following error message: "Input string was not in a
correct format."
I use the following function in a validating class to use
when needed. (Value = H880118A gave the error (like
other 'unconvertible' strings))
Public Function Numeric(ByVal value) As Boolean

Hi,
I am having problems with using the DrawToDC of the
MSHTML.iHTMLElementRender in a VB.net application. For some reason I am
getting a "catastrophic error". I am basing the code on c# examples, and I
am not sure what exactly I am doing wrong. From the C# posts it seems that
the drawtodc has a bug and you need to redifine it, so i followed their
advice and specified an interface as below:

I have a program (posted below) that is supposed to take liters, which is
the user input, and convert it to pints and gallons. The pints and gallons
are displayed in a read only textbox. I don't understand how to fix the
problem.

I have set Option Strict On
I also have Enum AssemblyLineStatus As Integer
My question is how come there is no compilation error when I compile
following code?
If CInt(ddlStatus.SelectedItem.Value) = AssemblyLineStatus.Client Then
' do whatever
End If
Shouldn't this cause a compilation error? I know in C#, you have to

I found on error resume next doesn't work in for each... e.g.
on error resume next
for each x in y
'do stuff
next
if you have an error in for each loop, it falls in infinite loop... it
doesn't move to next element... this sad thing but, it's indication
that we must move to try catch instead of on error.

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
