Hi,

How create MsgBox or any analog of that function in ASP.Net?

Thanks

Jul,

By instance,
\\\
Page.RegisterClientScriptBlock("clientScript", scriptString)
Dim str As String = "<script language " & _
"=javascript>alert('I hope this helps a little bit?');</script>"
Page.RegisterStartupScript("Startup", str)
///

I hope this helps?

Yes, it helps, but also couple questions:
1. Why I need to call RegisterClientScriptBlock?
2. Why after I press "Refresh (F5)" I get the message " The page cannot be
refreshed without resending the information..." . When I click "Retry" the
alert dialog appear again, but it has to appear only (in my case) when I
click Button on the form.

Thanks

Jul,

but it has to appear only (in my case) when I click Button on the form.

Than you have to ask that. You can place in the load event of the page.
Me.Button1.Attributes("onClick") = "alert('I hope this helps a little
bit?');"

I hope this helps?

But can I include script/code to the Private Sub Button1_Click?
or always has to be in Load Event of the page?


and what cases I need to use RegisterClientScriptBlock or
RegisterStartupScript

Jul,

Register startup is "onload"
The attribute you can use where you want, don't forget that every sent the
information is refreshed.

I hope this helps?
