This program in asp.net 2.0 is a Spanish/English Dictionary.
It consists of two textboxes,one button and a datalist. The datalist is bound to an acces database consisting of two columns; One Spanish and one English. When a user enters a Spanish word in textbox1 and clicks the button, the meaning of the word appears in textbox2. Now sometimes a user enters a word that is not in the database. I want, in this case, to have a javascript messagebox to popup saying “Either the word is not listed or misspelled”.
I tried several javascripts to popup in code behind but that did not work. I know that a clientside should be included but I am not able to do that.
The sub below is the one I am using to fetch the words and it is working perfect as long as I enter a word that is already in access database. The words in the rows in database are separated by hyphens so I am using a “Split” fuction which is also working perfectly.

I think that I would probably include the JavaScript into the page (in the <head> section of the page) so that you can call it on the JavaScript's window onload event. Have the JavaScript function check a HiddenField on the page to determine whether or not the message should be displayed....se t the HiddenField in your C# or VB.NET server-side code.

Hello all,
I have simple function that I call from an alert box
alert(testScore);
It works fine. Unfortunately, I do not like the sound and Exclamation
point icon that appears. I'd like a nice message box like VBA message
box #64 to appear. I know hardly anything at all about VB or VBA.
But, I do know you can call a VB function from Javascript. How? Is it

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

Does anyone know how I might use the webclient class to navigate to a web
page in a vb.net app, and then if a JavaScript popup appears from the web
page I go to, read the message in it or content of it, then close it so I
can continue on.
I don't know how to reference the popup box or send a command to click the
ok button to close it.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
