I always thought writing a simple diagnostic message in a message box would
be pretty simple. Not in .NET.
First, I wrote this amazingly complex piece of code:
MessageBox.Show ("yer mama")
It wouldn't even complile. "Gee...", I mused. "Maybe there's no reference
to that method in my project". I muzed correctly. So I added a reference
to System.Windows. Forms, which is where our beloved "MessageBox " method
resides.
Nothing. So at the top of my file, I wrote:
Imports System.Windows. Forms
Still, it wouldn't compile. Finally, I prefixed my call to MessageBox like
this:
System.Windows. Forms.MessageBo x.Show("yer mama")
It compiles now, but I never see "yer mama" anywhere on the screen. It's
inside this function:
Private Sub DropDownList1_S electedIndexCha nged(ByVal sender As
System.Object, ByVal e As System.EventArg s) Handles
DropDownList1.S electedIndexCha nged
System.Windows. Forms.MessageBo x.Show("Yer mama")
End Sub
Maybe it's just not firing this sub, but that's kinda why the diagnostic is
there. I wanna find out if it is. Does this really have to be so
complicated?
I've run into situations in the past where I've had to spell out simple
methods by fully qualifying their namespaces. Why is that? Shouldn't it be
enough that they're listed under "references " in the solution explorer? Or
even written manually at the top of the file?
Any insights you can give me would be greatly appreciated. 5 1560

If you want to tell if the event handler is being executed, a breakpoint
would probably be better. Also, you might want to think about the
Debug.Write and Debug.WriteLine methods, in the System.Diagnost ics
namespace. You don't have to add any extra references for those, and the
namespace is imported at the project level by default. Just make sure
you're targeting a Debug build.

There are a lot of namespaces, and some of them have identical class
names. If everything was automatically imported, it would clog up the IDE
and lead to a lot of ambiguity. Odds are your code would have to use the
fully-qualified name -more- that way.

As the namespace implies, the MessageBox method is for windows forms
applications.
In an ASP.NET environment your client is a web browser, therefore you should
use client side code such as javascript to display a message box on the
client.
Execute a line of code like this when you want a message box to be
displayed.
(This writes out the necessary client side javascript to your HTML page to
make the alert pop up as soon as the page is sent to their browser.)
RegisterStartup Script("startup Script", "<script
language=JavaSc ript>alert('Thi s is my message.');</script>");

Hi Steve,
I think that I would not have seen this, however I look to it from the
languages.vb group, when it was in the aspnet group, I would have seen.
I message this to point the OP hat this message is in my opinion the right
one, there are so much which are for the windowform, that he can become
confused.
And have nothing to add.
Cor
Maybe it does not like "yer mama" in the message box?
Curt, looking at your example code below, your message box is in the event
firing on a DropDownList1, which is an ASP component, so you are talking
about using MessageBox in an ASP page, right? If so, it won't work.

Hi all,
I have a VB.NET windows application that uses MDI form. When I try to delete a datagrid row from one of the MDI children forms, I use a MessageBox YesNo confirmation, which, after confirmed, minimizes the MDI form. Why is this happening and how can I prevent it?
Important thing to say is, if I use just "OK" MessageBox, it DOES NOT minimize the MDI parent.
TIA
