Hello, My question is, after logging in, i've reached the main page. Then i would like a messageBox to pop out saying that "You have entered *this* page". It has to pop out as soon as I enter the page. Please help as time is not on my side. Thanks a lot. :)
What is this? A webapp in asp.net or a desktop app with Winforms?
A webapp in asp.net using vb.net.
Ok, I can move this thread to the proper forum then.
Codebank is for finished tips and tricks etc. ;)
Add some javascript to the page.
<script type="text/JavaScript">
alert('Hello, welcome to this page.');
</script>
You can also use ClientScript.RegisterStartupScript() to output javascript to the page.
Can we use these scripts in the webapplication? where do I insert this codes? I'm quite lost here. Can't we write it in vb.net format?
Thanks.
Nope, what you have to think of is that, within an Internet/Intranet application, the webserver simply serves up and posts web pages it has, when users request the pages. Those pages are then disconnected and have no more to do with the server at all - they're simply rendered within the user's browser.Quote:
Can't we write it in vb.net format?
So writing server side code to bring up an operating system messagebox isn't available, all you have is the ability of throwing up a browser alert box via the use of a client side scripting language, such as Javascript.
Well assuming you want to show this alert when the page is first displayed to the user, then you can place the above code within the HTML, like so:Quote:
Where do I insert this codes? I'm quite lost here.
Code:<html>
<head>
<script language="javascript">
function ShowMeTheMessage() {
alert('Hello world!');
}
</script>
</head>
<body onLoad="javascript: ShowMeTheMessage();">
</body>
</html>
Ok. But how do I convert these codes into the vb.net format? Like which part do I write these codes? the showmethemessage box, will i have to change it to MsgBox("Hello world")? Is it like that? Please explain and show me. Thanks.
Again you can't really use VB.Net here, you need to use a client scripting language such as VBScript or JavaScript. As JavaScript is supported on more browsers, I've opted to write the sample in that above. You'd be able to see looking at that where I've written the wording "hello world" in :p ;) it's this part (it doesn't really matter if you use single or double quotes to surround the string in Javascript):
Basically these 2 are the same thing, top in Javascript, 2nd in VBNetCode:alert('Hello world!');
and these 2 are the same:Code:function ShowMeTheMessage() {
}
Private Function ShowMeTheMessage
End Function
Code:alert('Hello world!');
Messagebox.Show("Hello world!")
Oh ok. Thanks a lot. I'll try that. Thanks again. Been a great help. :P
vb Code:
That's how you'd do it from your codebehind to dynamically generate an alert box with your message in it. You can call it from any event such as Page Load, a Button Click and so on.
ShowTheMessage("Hello World")
