Dumb question about Message boxes

Re: Dumb question about Message boxes

It seems that you are talking about Web app. Do you really want to show a
MessageBox on the web server, while user sits in front of a web browser
thousands kilometers away? How does the user know a MessageBox pops up on
the web server? In Web app, if you want to nitify user something, you should
have the web server send back a page to user, either in the same browser
window or in a new browser window.

By the way, MessageBox is in System.Windows. Forms namespace, which is not
referenced in web app by default. That is why you get error "Not declared".

Re: Dumb question about Message boxes

What I am doing is writing validation for a Web form. If data is entered
incorrectly, I want a messagebox to notify the user the data type is
incorrect...I tried putting in the Name Space for System.Window, but that
did not work either. Ugh! This used to be simple! thanks for any/all of
your help.

Re: Dumb question about Message boxes

When I put System.Windows. Forms in the Namespace I get the blue squiggly
line with the message "Namespace or type 'forms' for the Imports
'System.Windows .forms' cannot be found. What's up with that? Usually, when
you put in the Namespace, the choices pop-up after you type the . but in
this case, Windows does not come up as one of the available choices under
System! How can I put in a Namespace when it is not available or supported?

Re: Dumb question about Message boxes

If you are writing a web application (e.g. Webform), then the System.Windows
namespace is not available. This namespace is meant for WindowsForms
applications.

Adding a "using" or "Imports" statement at the top of the code file is not
the same as ading a reference. To add a reference use the project
explorer. Right-click on the "references " folder as select "Add
reference..." Then browse for "System.Windows .Forms".

When you create a "Windows Forms Application" in the new project wizard it
does this or you. On the other hand you should not be using windows forms
in a web application, which is why that reference is not made.

What you want is a scripting message box. It will appear on the client
side of the web page. I have not made one in ASP.NET, but it won't be that
different from ASP.

See the following link. It shows how to do it with both Javascript and
VBscript:

Re: Dumb question about Message boxes

Thank you! I was just informed by one of my co-workers that I would need to
do my form validation using JavaScript - unfortunately I have NO knowledge
of JavaScript, so this is good news that I can do it in VB Script! Thanks

Re: Dumb question about Message boxes

But you really shouldn't do it in VBScript, since Netscape browsers don't
support VBScript.

In a nutshell Colleen, it wasn't that different in Classic ASP. You
couldn't ask for a msgbox() in classic ASP either because message boxes are
not produced by the server, they are produced by the browser. Since
server-side code executes, well at the server, asking for a messagebox is
out of the question. All requests for messageboxes/alerts must be made at
the client level.

Re: Dumb question about Message boxes

Which is fine and dandy, if you know JavaScript, but I don't! So I am
looking for an alternative. If I have to use JavaScript, then I have to,
but do you have any suggestions for a VERY beginner? I have no idea even
where to start. Where do I write the code? In the aspx portion, or the
code behind? I haven't a clue... Thanks for any suggestions :-)

See my other post...

JavaScript IS the answer you are looking for. In today's world of web
development, JavaScript is a must know.
