If an ActiveX control is created in .Net and is used on a Asp .Net page does the client need to have the .Net framework installed in order for the control to work?

Yes, if the ActiveX based on .NET Framework.
you should use ATL if you want to clients access normal without .Net Framework

Glad to discuss with you and best wishes.

You may have to solve this with some Javascript, so that you can trap the user when they press the Backspace Key on the keyboard.

function fOnKeypress() {

  try {
    
	var charCode = window.event.keyCode;
	
	if (charCode == 13) {
      window.event.keyCode= 9;
	}
  }
  catch (er) {
		    //alert('fOnKeypress ' + er);
  }
}

You will need to load this in the BODY OnLoad event. I'm usign something like this:

var objForm= document.getElementById("aspnetForm");     // There should be a better way to get the name of the form instead of hard-coding it like this.
   objForm.onkeydown=fOnKeypress;

Very easy to enable or disable a button through C#. If your page has the following button:

<asp:Button ID="Button1" runat="server" Text="Click me" onclick="Button1_Click" />

Then you can enable/disable it in your code-behind file through setting its 'enabled' property:

Button1.Enabled = false;

or

Button1.Enabled = true

Hope this helps! Smile | :)

Hope you are talking about the browser back button.
You cannot disable the back button if the browser instance is opened and your URL is typed in the address bar.
However you have control over the window which you are opening from your code.
So the only way to solve your problem is to have a default startup page in which you have to do a opendialog for your homepage and pass the arguments disbaling the menu bars and titlebars.

In my form, I have Update Panels and also Update Progress Controls. I want the UpdateProgress controls should not fire and shows the text "Loading..." when the SelectedIndex is -1. Is it possible to do so? If so, how? Sleepy | :zzz:

Anybody can provide any help on this? Thanks in advance.

Following is the code I have written:

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
               <ContentTemplate>
        <asp:DropDownList ID="UserTypeList" runat="server" AppendDataBoundItems="true"
               Width="155px">
                <asp:ListItem Selected="True" Text="--Please Select--" Value="-1"></asp:ListItem>
           </asp:DropDownList>
           <asp:UpdateProgress ID="UpdateProgress1" AssociatedUpdatePanelID="UpdatePanel1" runat="server" >
           <ProgressTemplate><span class="ProgressBar" >
           Loading...</span>
           </ProgressTemplate>
           </asp:UpdateProgress>
           </ContentTemplate>
           </asp:UpdatePanel>

Success is the good fortune that comes from aspiration, desperation, perspiration and inspiration.

It seems NO, you can set 'Loading' text to 'UpdateProgress'.
it will display 'Loading' when the page is loading...

Give an id for the span say "spanProgress"
Add handlers for beginrequest and endrequest

Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(onBeginRequest);
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(onEndRequest);

function onBeginRequest()
{
//add your logic for checking SelectedIndex == -1 and then hide the span
//by setting document.getElementById("spanProgress").style.display="none";
}
function onEndRequest()
{
//enable the span here
}

It is really rude to give the requirements and expect someone to code for you.

i don't think it is rude, but i don't even want to go into discussion with someone who makes those remarks. if you have a problem and you don't know the answer it is quite common to communicate in a civil way about this. why else do you buy books with examples and does the internet exists with loads of comments and examples about things. isn't that the way you began when you first started programming. so please don't go this way and act like an adult or else don't reply on this post.

Tell me Something,

Do you really understand what that vb6 DLL does ? if you do why don't you write the Functionality in .NET

With VB6 stuff you will always have Problems when you bring them to the world of .NET
