Accept User Input Through an Input Box or Form

[Tript99]

Hellow,
I'm working on a webform in VB.net and I would like the user to be able to click a button and have an input box pop up so they can input a string that will be later used in an sql statement. When I try to run my code I get errors saying:

An unhandled exception of type 'System.InvalidOperationException' occurred in Unknown Module.

Additional information: It is invalid to show a modal dialog or form when the application is not running in UserInteractive mode. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

It sounds like there is no input box for VB.net. Can anyone tell me the best way to get around this? I'm thinking I might have to create another form and make it active when the button is clicked but I'm not sure how to do that either. I am trying to grind through this stuff without any proper training so any help would be awesome.

Here is my code:

Private sub ManualSearch_Click
Dim strSearch As String
strSearch = funInputBox(strMessage)
End Sub

Function funInputBox(ByVal strMessage As String) As String
Dim message, title, defaultValue As String
Dim myValue As Object
title = "Manual Product Search" ' Set title.
funInputBox = InputBox(message, title, defaultValue)
End Function


Thanks,
Tript.

you probably created a service application instead of a windowsapplication.

Hmm.. I'm not sure what that means. I'm trying to create a web based app. What is the difference?

I'm trying to create a web based app. What is the difference?

Well, a web-based app runs on the Internet and users access it through a web browser. A VB.NET desktop application (what this forum is for) is a program that runs locally on the users machine (and InputBox is a Windows Forms class and as such can't be used in a web based app).

If you want to create pop up boxes for an ASP.NEt application then you will have to use javascript or another client side language.
